    Disable the asserts that check that normalization is perfectly
    invertible. ScalarEvolution's folding routines don't always succeed
    in canonicalizing equal expressions to a single canonical form, and
    this can cause these asserts to fail, even though there's no actual
    correctness problem. This fixes PR8066.

    previous patch was a little too tricky for its own good. Don't try to

    Re-apply r112883:
    "For ARM stack frames that utilize variable sized objects and have either
    large local stack areas or require dynamic stack realignment, allocate a
    base register via which to access the local frame. This allows efficient
    access to frame indices not accessible via the FP (either due to being out
    of range or due to dynamic realignment) or the SP (due to variable sized
    object allocation). In particular, this greatly improves efficiency of access
    to spill slots in Thumb functions which contain VLAs."

    r112986 fixed a latent bug exposed by the above.

    VirtRegRewriter checks for early clobbers before it reuses an available stack
    slot.

    Teach it to also check for early clobbered aliases, and early clobber operands
    following the current operand.

    This fixes the miscompilation in PR8044 where EC registers eax and ecx were
    being used for inputs.

    Check the local frame alignment for determining whether dynamic stack
    alignment should be performed. Otherwise dynamic realignment may trigger
    when the register allocator has already used the frame pointer as a general
    purpose register. That is, we need to make sure that the list of reserved
    registers doesn't change after register allocation.

    the 2.8 branch deadline, I'll have to leave the rest of the instructions

    Fix cmake build without native target selected.

    The cmake (+ MSVC) build is broken if you don't select your native
    target.

    e.g. 'cmake -D LLVM_TARGETS_TO_BUILD="MyNonNativeTarget" .'

    This is because cmake currently sets the LLVM_NATIVE_* definitions
    regardless of whether the native target is selected (causing build
    errors).

    reapply 112894:

    Remove #uses comments from functions: they we're padded out to column 50
    and were potentially confusing for externally visible functions.

    going further, remove the "<i8**> [#uses=3]" comments entirely. They
    add a lot of noise, confuse people about what the IR is, and don't add
    any particular value.  When the types are long it makes it really really
    hard to read IR.

    If someone is interested in this sort of thing, the right way to do this
    is to implement an AsmAnnotationWriter that produces the same output, and
    add a flag to llvm-dis (only) to produce this output.

    Remove #uses comments from functions: they we're padded out to column 50
    and were potentially confusing for externally visible functions.

    going further, remove the "<i8**> [#uses=3]" comments entirely. They
    add a lot of noise, confuse people about what the IR is, and don't add
    any particular value.  When the types are long it makes it really really
    hard to read IR.

    If someone is interested in this sort of thing, the right way to do this
    is to implement an AsmAnnotationWriter that produces the same output, and
    add a flag to llvm-dis (only) to produce this output.

    Use the FindProgramByName fallback only with known absolute paths.

    For ARM stack frames that utilize variable sized objects and have either
    large local stack areas or require dynamic stack realignment, allocate a
    base register via which to access the local frame. This allows efficient
    access to frame indices not accessible via the FP (either due to being out
    of range or due to dynamic realignment) or the SP (due to variable sized
    object allocation). In particular, this greatly improves efficiency of access
    to spill slots in Thumb functions which contain VLAs.

    - Change __builtin_ia32_palignr intrinsic type to match the pattern in clang.

    - Add patterns to match the following MMX builtins:

       * __builtin_ia32_vec_init_v8qi
       * __builtin_ia32_vec_init_v4hi
       * __builtin_ia32_vec_init_v2si
       * __builtin_ia32_vec_ext_v2si

      These builtins do not correspond to a single MMX instruction. They will have
      to be lowered -- most likely in the back-end.

    Don't narrow the load and store in a load+twiddle+store sequence unless
    there are clearly no stores between the load and the store. This fixes
    this miscompile reported as PR7833.

    safe, but awkward to prove safe. Move it to X86's README.txt.

    Using target specific nodes for shuffle nodes makes the mask
    check more strict, breaking some cases not checked in the
    testsuite, but also exposes some foldings not done before,
    as this example:

      movaps  (%rdi), %xmm0
      movaps  (%rax), %xmm1
      movaps  %xmm0, %xmm2
      movss %xmm1, %xmm2
      shufps  $36, %xmm2, %xmm0

    now is generated as:

      movaps  (%rdi), %xmm0
      movaps  %xmm0, %xmm1
      movlps  (%rax), %xmm1
      shufps  $36, %xmm1, %xmm0

    Make tool_output_file's raw_ostream instance a member variable instead
    of a base class.

    This makes it possible to unregister the file from FilesToRemove when
    the file is done. Also, this eliminates the need for
    formatted_tool_output_file.

    add a gross hack to work around a problem that Argiris reported
    on llvmdev: SRoA is introducing MMX datatypes like <1 x i64>,
    which then cause random problems because the X86 backend is
    producing mmx stuff without inserting proper emms calls.

    In the short term, force off MMX datatypes.  In the long term,
    the X86 backend should not select generic vector types to MMX
    registers.  This is being worked on, but won't be done in time
    for 2.8.  rdar://8380055

    This is the second of three patches to implement support for the .loc directive
    and output the dwarf line number tables.  This takes the current loc info after
    an instruction is assembled and saves the needed info into an object that has
    vector and for each section.  These objects will be used for the final patch to
    build and emit the encoded dwarf line number tables.  Again for now this is only
    in the Mach-O streamer but at some point will move to a more generic place.

Author: Bill Wendling <isanbard@gmail.com>

    We have a chance for an optimization. Consider this code:

    int x(int t) {
      if (t & 256)
        return -26;
      return 0;
    }

    We generate this:

         tst.w   r0, #256
         mvn     r0, #25
         it      eq
         moveq   r0, #0

    while gcc generates this:

         ands    r0, r0, #256
         it      ne
         mvnne   r0, #25
         bx      lr

    Scandalous really!

    During ISel time, we can look for this particular pattern. One where we have a
    "MOVCC" that uses the flag off of a CMPZ that itself is comparing an AND
    instruction to 0. Something like this (greatly simplified):

      %r0 = ISD::AND ...
      ARMISD::CMPZ %r0, 0         @ sets [CPSR]
      %r0 = ARMISD::MOVCC 0, -26  @ reads [CPSR]

    All we have to do is convert the "ISD::AND" into an "ARM::ANDS" that sets [CPSR]
    when it's zero. The zero value will all ready be in the %r0 register and we only
    need to change it if the AND wasn't zero. Easy!

    Track liveness of unallocatable, unreserved registers in machine DCE.

    Reserved registers are unpredictable, and are treated as always live by machine
    DCE.

    Allocatable registers are never reserved, and can be used for virtual registers.

    Unreserved, unallocatable registers can not be used for virtual registers, but
    otherwise behave like a normal allocatable register. Most targets only have
    the flag register in this set.

    Add a micro-test for the transforms I added to JumpThreading.

    I have not been able to find a way to test each in isolation, for a few reasons:
    1) The ability to look-through non-i1 BinaryOperator's requires the ability to look through non-constant
       ICmps in order for it to ever trigger.
    2) The ability to do LVI-powered PHI value determination only matters in cases that ProcessBranchOnPHI
       can't handle.  Since it already handles all the cases without other instructions in the def-use chain
       between the PHI and the branch, it requires the ability to look through ICmps and/or BinaryOperators
       as well.

    Improve virtual frame base register allocation heuristics.

      1. Allocate them in the entry block of the function to enable function-wide
         re-use. The instructions to create them should be re-materializable, so
         there shouldn't be additional cost compared to creating them local
         to the basic blocks where they are used.
      2. Collect all of the frame index references for the function and sort them
         by the local offset referenced. Iterate over the sorted list to
         allocate the virtual base registers. This enables creation of base
         registers optimized for positive-offset access of frame references.
         (Note: This may be appropriate to later be a target hook to do the
         sorting in a target appropriate manner. For now it's done here for
         simplicity.)

    More Chris-inspired JumpThreading fixes: use ConstantExpr to correctly constant-fold undef, and be more careful with its return value.
    This actually exposed an infinite recursion bug in ComputeValueKnownInPredecessors which theoretically already existed (in JumpThreading's
    handling of and/or of i1's), but never manifested before.  This patch adds a tracking set to prevent this case.

    Add experimental -disable-physical-join command line option.

    Eventually, we want to disable physreg coalescing completely, and let the
    register allocator do its job using hints.

    This option makes it possible to measure the impact of disabling physreg
    coalescing.

    two changes:
    1) nuke ConstDataCoalSection, which is dead.
    2) revise my previous patch for rdar://8018335,
      which was completely wrong.  Specifically, it doesn't
      make sense to mark __TEXT,__const_coal as PURE_INSTRUCTIONS,
      because it is for readonly data.  templates (it turns out)
      go to const_coal_nt.  The real fix for rdar://8018335 was
      to give ConstTextCoalSection a section kind of ReadOnly
      instead of Text.

    When expanding NEON VST pseudo instructions, if the original super-register
    operand is killed, add it to the expanded instruction as an implicit kill
    operand instead of marking the individual subregs with kill flags.  This
    should work better in general and also handles the case for VST3 where one
    of the subregs was not referenced in the expanded instruction and so was
    not marked killed.

    It is possible to try to merge a not-constant with a constantrage, when dealing with ptrtoint ConstantExpr's.
    Unfortunately, the only testcase I have for this is huge and doesn't reduce well because the error is
    sensitive to iteration-order issues, since the problem only occurs when merging values in a particular order.

    Remove a hack that tries to understand incorrect triples from the
    Triple class constructor.  Only valid triples should now be used
    inside LLVM - front-ends are now responsable for rejecting or
    correcting invalid target triples.  The Triple::normalize method
    can be used to straighten out funky triples provided by users.
    Give this a whirl through the buildbots to see if I caught all
    places where triples enter LLVM.

    Create Thumb2sI_cpsr and T2sI_cpsr. These new classes indicate that CPSR is the
    optional modified register (instead of reg0). Along with r112461 it will make
    sure that the optional define of CPSR is marked as "def" and will thus mark the
    instructions using these classes (t2ANDS*) as setting the 's' flag.

    When adding a register, we should mark it as "def" if it can optionally define
    said (physical) register.

    rewrite DwarfEHPrepare to use SSAUpdater to promote its allocas
    instead of PromoteMemToReg.  This allows it to stop using DF and DT,
    eliminating a computation of DT and DF from clang -O3.  Clang is now
    down to 2 runs of DomFrontier.

    two changes: 1) make AliasSet hold the list of call sites with an
    assertingvh so we get a violent explosion if the pointer dangles.

    2) Fix AliasSetTracker::deleteValue to remove call sites with
       by-pointer comparisons instead of by-alias queries.  Using
       findAliasSetForCallSite can cause alias sets to get merged
       when they shouldn't, and can also miss alias sets when the
       call is readonly.

    #2 fixes PR6889, which only repros with a .c file :(

    fix some bugs (found by inspection) where LICM would not update
    LICM correctly.  When sinking an instruction, it should not add
    entries for the sunk instruction to the AST, it should remove
    the entry for the sunk instruction.  The blocks being sunk to
    are not in the loop, so their instructions shouldn't be in the
    AST (yet)!

    rework the ownership of subloop alias information: instead of
    keeping them around until the pass is destroyed, keep them
    around a) just when useful (not for outer loops) and b) destroy
    them right after we use them.  This should reduce memory use
    and fixes potential bugs where a loop is deleted and another
    loop gets allocated to the same address.

    Stop explicitly scheduling domfrontier before the loop passes,
    since none of them use it.  With this, we now only run
    domfrontier (an N^2 analysis) 3 times at clang -O3: once for
    "early" per-function cleanup, once at the start of the
    per-function pipeline to support SRoA, and once late because
    the EHPrepare class uses it.

    EHPrepare needs to stop using it, this is silly and wasteful.

    when merging two alias sets, the result set is volatile if either
    of the sets is volatile.  We were dropping the volatile bit of the
    merged in set, leading (luckily) to assertions in cases like
    PR7535.  I cannot produce a testcase that repros with opt, but this
    is obviously correct.

    I have manually decoded the imm field of an insertps one too many
    times.  This patch causes llc and llvm-mc (which both default to
    verbose-asm) to print out comments after a few common shuffle
    instructions which indicates the shuffle mask, e.g.:

    	insertps	$113, %xmm3, %xmm0     ## xmm0 = zero,xmm0[1,2],xmm3[1]
    	unpcklps	%xmm1, %xmm0    ## xmm0 = xmm0[0],xmm1[0],xmm0[1],xmm1[1]
    	pshufd	$1, %xmm1, %xmm1        ## xmm1 = xmm1[1,0,0,0]

    This is carefully factored to keep the information extraction (of the
    shuffle mask) separate from the printing logic.  I plan to move the
    extraction part out somewhere else at some point for other parts of
    the x86 backend that want to introspect on the behavior of shuffles.

    fix the buildvector->insertp[sd] logic to not always create a redundant
    insertp[sd] $0, which is a noop.  Before:

    _f32:                                   ## @f32
    	pshufd	$1, %xmm1, %xmm2
    	pshufd	$1, %xmm0, %xmm3
    	addss	%xmm2, %xmm3
    	addss	%xmm1, %xmm0
                                            ## kill: XMM0<def> XMM0<kill> XMM0<def>
    	insertps	$0, %xmm0, %xmm0
    	insertps	$16, %xmm3, %xmm0
    	ret

    after:

    _f32:                                   ## @f32
    	movdqa	%xmm0, %xmm2
    	addss	%xmm1, %xmm2

    	pshufd	$1, %xmm0, %xmm3
    	addss	%xmm1, %xmm3
    	movdqa	%xmm2, %xmm0
    	insertps	$16, %xmm3, %xmm0
    	ret

    The extra movs are due to a random (poor) scheduling decision.

    fix the BuildVector -> unpcklps logic to not do pointless shuffles
    when the top elements of a vector are undefined.  This happens all
    the time for X86-64 ABI stuff because only the low 2 elements of
    a 4 element vector are defined.  For example, on:

    _Complex float f32(_Complex float A, _Complex float B) {
      return A+B;
    }

    We used to produce (with SSE2, SSE4.1+ uses insertps):

    _f32:                                   ## @f32
    	movdqa	%xmm0, %xmm2
    	addss	%xmm1, %xmm2
    	pshufd	$16, %xmm2, %xmm2
    	pshufd	$1, %xmm1, %xmm1
    	pshufd	$1, %xmm0, %xmm0
    	addss	%xmm1, %xmm0
    	pshufd	$16, %xmm0, %xmm1
    	movdqa	%xmm2, %xmm0
    	unpcklps	%xmm1, %xmm0
    	ret

    We now produce:

    _f32:                                   ## @f32
    	movdqa	%xmm0, %xmm2
    	addss	%xmm1, %xmm2
    	pshufd	$1, %xmm1, %xmm1
    	pshufd	$1, %xmm0, %xmm3
    	addss	%xmm1, %xmm3
    	movaps	%xmm2, %xmm0
    	unpcklps	%xmm3, %xmm0

    Don't cast Win32 FILETIME structs to int64. Patch by Dimitry Andric!

    According to the Microsoft documentation here:
    http://msdn.microsoft.com/en-us/library/ms724284%28VS.85%29.aspx

    this cast used in lib/System/Win32/Path.inc:

    __int64 ft = *reinterpret_cast<__int64*>(&fi.ftLastWriteTime);

    should not be done.  The documentation says: "Do not cast a pointer to a
    FILETIME structure to either a ULARGE_INTEGER* or __int64* value because
    it can cause alignment faults on 64-bit Windows."

    Clean up the logic of vector shuffles -> vector shifts.
    Also teach this logic how to handle target specific shuffles if
    needed, this is necessary while searching recursively for zeroed
    scalar elements in vector shuffle operands.

    handle the constant case of vector insertion.  For something
    like this:

    struct S { float A, B, C, D; };

    struct S g;
    struct S bar() {
      struct S A = g;
      ++A.B;
      A.A = 42;
      return A;
    }

    we now generate:

    _bar:                                   ## @bar
    ## BB#0:                                ## %entry

    instead of:

    optimize bitcasts from large integers to vector into vector
    element insertion from the pieces that feed into the vector.
    This handles a pattern that occurs frequently due to code
    generated for the x86-64 abi.  We now compile something like
    this:

    struct S { float A, B, C, D; };
    struct S g;
    struct S bar() {
      struct S A = g;
      ++A.A;
      ++A.C;
      return A;
    }

    into all nice vector operations:

    _bar:                                   ## @bar
    ## BB#0:                                ## %entry
    	movq	_g@GOTPCREL(%rip), %rax
    	movss	LCPI1_0(%rip), %xmm1
    	movss	(%rax), %xmm0
    	addss	%xmm1, %xmm0
    	pshufd	$16, %xmm0, %xmm0
    	movss	4(%rax), %xmm2
    	movss	12(%rax), %xmm3
    	pshufd	$16, %xmm2, %xmm2
    	unpcklps	%xmm2, %xmm0
    	addss	8(%rax), %xmm1
    	pshufd	$16, %xmm1, %xmm1
    	pshufd	$16, %xmm3, %xmm2
    	unpcklps	%xmm2, %xmm1
    	ret

    instead of icky integer operations:

    _bar:                                   ## @bar
    	movq	_g@GOTPCREL(%rip), %rax
    	movss	LCPI1_0(%rip), %xmm1
    	movss	(%rax), %xmm0
    	addss	%xmm1, %xmm0
    	movd	%xmm0, %ecx
    	movl	4(%rax), %edx
    	movl	12(%rax), %esi
    	shlq	$32, %rdx
    	addq	%rcx, %rdx
    	movd	%rdx, %xmm0
    	addss	8(%rax), %xmm1

    	shlq	$32, %rsi
    	addq	%rax, %rsi

    Change ARM VFP VLDM/VSTM instructions to use addressing mode #4, just like
    all the other LDM/STM instructions.  This fixes asm printer crashes when
    compiling with -O0.  I've changed one of the NEON tests (vst3.ll) to run
    with -O0 to check this in the future.

    Prior to this change VLDM/VSTM used addressing mode #5, but not really.
    The offset field was used to hold a count of the number of registers being
    loaded or stored, and the AM5 opcode field was expanded to specify the IA
    or DB mode, instead of the standard ADD/SUB specifier.  Much of the backend
    was not aware of these special cases.  The crashes occured when rewriting
    a frameindex caused the AM5 offset field to be changed so that it did not
    have a valid submode.  I don't know exactly what changed to expose this now.
    Maybe we've never done much with -O0 and NEON.  Regardless, there's no longer
    any reason to keep a count of the VLDM/VSTM registers, so we can use
    addressing mode #4 and clean things up in a lot of places.

    Enhance the shift propagator to handle the case when you have:

    A = shl x, 42
    ...
    B = lshr ..., 38

    which can be transformed into:
    A = shl x, 4
    ...

    iff we can prove that the would-be-shifted-in bits
    are already zero.  This eliminates two shifts in the testcase
    and allows eliminate of the whole i128 chain in the real example.

    Implement a pretty general logical shift propagation
    framework, which is good at ripping through bitfield
    operations.  This generalize a bunch of the existing
    xforms that instcombine does, such as
      (x << c) >> c -> and
    to handle intermediate logical nodes.  This is useful for
    ripping up the "promote to large integer" code produced by
    SRoA.

Author: Chris Lattner <sabre@nondot.org>

    Add an instcombine to clean up a common pattern produced
    by the SRoA "promote to large integer" code, eliminating
    some type conversions like this:

       %94 = zext i16 %93 to i32                       ; <i32> [#uses=2]
       %96 = lshr i32 %94, 8                           ; <i32> [#uses=1]
       %101 = trunc i32 %96 to i8                      ; <i8> [#uses=1]

    This also unblocks other xforms from happening, now clang is able to compile:

    struct S { float A, B, C, D; };
    float foo(struct S A) { return A.A + A.B+A.C+A.D; }

    into:

    _foo:                                   ## @foo
    ## BB#0:                                ## %entry
    	pshufd	$1, %xmm0, %xmm2
    	addss	%xmm0, %xmm2
    	movdqa	%xmm1, %xmm3
    	addss	%xmm2, %xmm3
    	pshufd	$1, %xmm1, %xmm0
    	addss	%xmm3, %xmm0
    	ret

    on x86-64, instead of:

    _foo:                                   ## @foo
    ## BB#0:                                ## %entry
    	movd	%xmm0, %rax
    	shrq	$32, %rax
    	movd	%eax, %xmm2
    	addss	%xmm0, %xmm2
    	movapd	%xmm1, %xmm3
    	addss	%xmm2, %xmm3
    	movd	%xmm1, %rax
    	shrq	$32, %rax
    	movd	%eax, %xmm0
    	addss	%xmm3, %xmm0
    	ret

    This seems pretty close to optimal to me, at least without
    using horizontal adds.  This also triggers in lots of other
    code, including SPEC.

    Fix the msvs 2010 build.

    The Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.30319.01
    implements parts of C++0x based on the draft standard. An old version of
    the draft had a bug that makes std::pair<T1*, T2*>(something, 0) fail to
    compile. This is because the template<class U, class V> pair(U&& x, V&& y)
    constructor is selected, even though it later fails to implicitly convert
    U and V to frist_type and second_type.

    This has been fixed in n3090, but it seems that Microsoft is not going to
    update msvc.

    optimize bitcast(trunc(bitcast(x))) where the result is a float and 'x'

    Reapply r112091 and r111922, support for metadata linking, with a
    fix: add a flag to MapValue and friends which indicates whether
    any module-level mappings are being made. In the common case of
    inlining, no module-level mappings are needed, so MapValue doesn't
    need to examine non-function-local metadata, which can be very
    expensive in the case of a large module with really deep metadata
    (e.g. a large C++ program compiled with -g).

    This flag is a little awkward; perhaps eventually it can be moved
    into the ClonedCodeInfo class.

commit be815c0090189c08f618f74365954c1ceea40312

    There seems to be a (potential) hardware bug with the CMN instruction and
    comparison with 0. These two pieces of code should give identical results:

      rsbs r1, r1, 0
      cmp  r0, r1
      mov  r0, #0
      it   ls
      mov  r0, #1

    and:

      cmn  r0, r1
      mov  r0, #0
      it   ls
      mov  r0, #1

    However, the CMN gives the *opposite* result when r1 is 0. This is because the
    carry flag is set in the CMP case but not in the CMN case. In short, the CMP
    instruction doesn't perform a truncate of the (logical) NOT of 0 plus the value
    of r0 and the carry bit (because the "carry bit" parameter to AddWithCarry is
    defined as 1 in this case, the carry flag will always be set when r0 >= 0). The
    CMN instruction doesn't perform a NOT of 0 so there is never a "carry" when this
    AddWithCarry is performed (because the "carry bit" parameter to AddWithCarry is
    defined as 0).

    The AddWithCarry in the CMP case seems to be relying upon the identity:

      ~x + 1 = -x

    However when x is 0 and unsigned, this doesn't hold:

       x = 0
      ~x = 0xFFFF FFFF
      ~x + 1 = 0x1 0000 0000
      (-x = 0) != (0x1 0000 0000 = ~x + 1)

    Therefore, we should disable *all* versions of CMN, especially when comparing
    against zero, until we can limit when the CMN instruction is used (when we know
    that the RHS is not 0) or when we have a hardware fix for this.

    (See the ARM docs for the "AddWithCarry" pseudo-code.)

    This is related to <rdar://problem/7569620>.

    SmallVector's growth policies don't like starting from zero capacity.
    I think there are good reasons to change this, but in the interests
    of short-term stability, make SmallVector<...,0> reserve non-zero
    capacity in its constructors.  This means that SmallVector<...,0>
    uses more memory than SmallVector<...,1> and should really only be
    used (unless/until this workaround is removed) by clients that
    care about using SmallVector with an incomplete type.

    Start converting NEON load/stores to use pseudo instructions, beginning here
    with the VST4 instructions.  Until after register allocation, we want to
    represent sets of adjacent registers by a single super-register.  These
    VST4 pseudo instructions have a single QQ or QQQQ source register operand.
    They get expanded to the real VST4 instructions with 4 separate D register
    operands.  Once this conversion is complete, we'll be able to remove the
    NEONPreAllocPass and avoid some fragile and hacky code elsewhere.

    Change handling of illegal vector types to widen when possible instead of
    expanding: e.g. <2 x float> -> <4 x float> instead of -> 2 floats.  This
    affects two places in the code: handling cross block values and handling
    function return and arguments.  Since vectors are already widened by
    legalizetypes, this gives us much better code and unblocks x86-64 abi
    and SPU abi work.

    For example, this (which is a silly example of a cross-block value):
    define <4 x float> @test2(<4 x float> %A) nounwind {
     %B = shufflevector <4 x float> %A, <4 x float> undef, <2 x i32> <i32 0, i32 1>
     %C = fadd <2 x float> %B, %B
      br label %BB
    BB:
     %D = fadd <2 x float> %C, %C
     %E = shufflevector <2 x float> %D, <2 x float> undef, <4 x i32> <i32 0, i32 1, i32 undef, i32 undef>
     ret <4 x float> %E
    }

    Now compiles into:

    _test2:                                 ## @test2
    ## BB#0:
     addps %xmm0, %xmm0
     addps %xmm0, %xmm0
     ret

    previously it compiled into:

    _test2:                                 ## @test2
    ## BB#0:
     addps %xmm0, %xmm0
     pshufd $1, %xmm0, %xmm1
                                            ## kill: XMM0<def> XMM0<kill> XMM0<def>
     insertps $0, %xmm0, %xmm0
     insertps $16, %xmm1, %xmm0

    ARM/Thumb2: Fix a misselect in getARMCmp, when attempting to adjust a signed

       adjusted the style to make it clear the transform is always valid.

    In the default address space, any GEP off of null results in a trap value if you try to load it.  Thus,
    any load in the default address space that completes implies that the base value that it GEP'd from

    First bit of support for the dwarf .loc directive.  This patch updates the
    needed parsing for the .loc directive and saves the current info from that
    into the context.  The next patch will take the current loc info after an
    instruction is assembled and save that info into a vector for each section for
    use to build the line number tables.  The patch after that will encode the info
    from those vectors into the output file as the dwarf line tables.

    This is the first step towards refactoring the x86 vector shuffle code. The
    general idea here is to have a group of x86 target specific nodes which are
    going to be selected during lowering and then directly matched in isel.

    The commit includes the addition of those specific nodes and a *bunch* of
    patterns, and incrementally we're going to switch between them and what we
    have right now. Both the patterns and target specific nodes can change as
    we move forward with this work.

    Create the new linker type "linker_private_weak_def_auto".

    It's similar to "linker_private_weak", but it's known that the address of the
    object is not taken. For instance, functions that had an inline definition, but
    the compiler decided not to inline it. Note, unlike linker_private and
    linker_private_weak, linker_private_weak_def_auto may have only default
    visibility.  The symbols are removed by the linker from the final linked image
    (executable or dynamic library).

    Introduce a new temporary MDNode concept. Temporary MDNodes are
    not part of the IR, are not uniqued, and may be safely RAUW'd.
    This replaces a variety of alternate mechanisms for achieving
    the same effect.

    If the target says that an extending load is not legal, regardless of whether
    it involves specific floating-point types, legalize should expand an
    extending load to a non-extending load followed by a separate extend operation.
    For example, we currently expand SEXTLOAD to EXTLOAD+SIGN_EXTEND_INREG (and
    assert that EXTLOAD should always be supported).  Now we can expand that to
    LOAD+SIGN_EXTEND.  This is needed to allow vector SIGN_EXTEND and ZERO_EXTEND
    to be used for NEON.

    CrashRecovery/Darwin: On Darwin, raise sends a signal to the main thread instead
    of the current thread. This has the unfortunate effect that assert() and abort()
    will end up bypassing our crash recovery attempts. We work around this for
    anything in the same linkage unit by just defining our own versions of the
    assert handler and abort.

    Fix the msvc 2010 build.

    The Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.30319.01
    implements parts of C++0x based on the draft standard. An old version of
    the draft had a bug that makes std::pair<T1*, T2*>(something, 0) fail to
    compile. This is because the template<class U, class V> pair(U&& x, V&& y)
    constructor is selected, even though it later fails to implicitly convert
    U and V to frist_type and second_type.

    This has been fixed in n3090, but it seems that Microsoft is not going to
    update msvc.

    If any def of a machine-sink candidate has local uses, it's obviously not safe to sink it to a successor block. This bug has been hidden because a later check for critical-edge disable these illegal optimizations. This patch should significantly reduce the amount of time spent on checking dominator information for obviously unsafe sinking.

    Revert r111394. It was too aggressive.

    We must complete the DFS, otherwise we might miss needed phi-defs, and
    prematurely color live ranges with a non-dominating value.

    This is not a big deal since we get to color more of the CFG and the next
    mapValue call will be faster.

    Add the LiveIntervalMap class. Don't hook it up yet.

    LiveIntervalMap maps values from a parent LiveInterval to a child interval that
    is a strict subset. It will create phi-def values as needed to preserve the
    VNInfo SSA form in the child interval.

    This leads to an algorithm very similar to the one in SSAUpdaterImpl.h, but with
    enough differences that the code can't be reused:

    - We don't need to manipulate PHI instructions.
    - LiveIntervals have kills.
    - We have MachineDominatorTree.
    - We can use df_iterator.

    decomposition that it is doing is very basicaa specific and is only used
    by basicaa.

    Add hook for re-using virtual base registers for local stack slot access.
    Nothing fancy, just ask the target if any currently available base reg
    is in range for the instruction under consideration and use the first one
    that is. Placeholder ARM implementation simply returns false for now.

    Tweak IVUsers' concept of "interesting" to exclude add recurrences
    where the step value is an induction variable from an outer loop, to

    Add materialization of virtual base registers for frame indices allocated into
    the local block. Resolve references to those indices to a new base register.
    For simplification and testing purposes, a new virtual base register is
    allocated for each frame index being resolved. The result is truly horrible,
    but correct, code that's good for exercising the new code paths.

    Next up is adding thumb1 support, which should be very simple. Following that
    will be adding base register re-use and implementing a reasonable ARM
    heuristic for when a virtual base register should be generated at all.

Author: Jim Grosbach <grosbach@apple.com>
Date:   Tue Aug 17 18:13:53 2010 +0000

    Add hook to examine an instruction referencing a frame index to determine
    whether to allocate a virtual frame base register to resolve the frame
    index reference in it. Implement a simple version for ARM to aid debugging.

    In LocalStackSlotAllocation, scan the function for frame index references
    to local frame indices and ask the target whether to allocate virtual
    frame base registers for any it encounters. Purely infrastructural for
    debug output. Next step is to actually allocate base registers, then add
    intelligent re-use of them.

    Make dumpPassStructure be a PMDataManager abstraction, rather than
    a Pass abstraction, since that's the level it's actually used at.
    Rename Pass' dumpPassStructure to dumpPass.

    This eliminates an awkward use of getAsPass() to convert a PMDataManager*
    into a Pass* just to permit a dumpPassStructure call.

    Better handle alignment requirements for local objects in pre-regalloc frame
    mapping. Have the local block track its alignment requirement, and then
    apply that when the block itself is allocated. Previously, offsets could
    get adjusted in PEI to be different, relative to one another, than the
    block allocation thought they would be, which defeats the point of doing
    the allocation this way. Continuing rdar://8277890

    Specialize FoldingSetTrait<SCEV>, providing implementations of node
    comparison and hash computation which don't require constructing
    temporary ID values.

commit f2d4a7583e8e77933d242776239bcb40da797268
Author: Dan Gohman <gohman@apple.com>
Date:   Mon Aug 16 15:30:39 2010 +0000

    Add hooks to FoldingSetTrait to allow specializations to provide
    implementations of equality comparison and hash computation. This
    can be used to optimize node lookup by avoiding creating lots of
    temporary ID values just for hashing and comparison purposes.

    Teach SimplifyCFG how to simplify indirectbr instructions.
     - Eliminate redundant successors.
     - Convert an indirectbr with one successor into a direct branch.

    Also, generalize SimplifyCFG to be able to be run on a function entry block.
    It knows quite a few simplifications which are applicable to the entry
    block, and it only needs a few checks to avoid trouble with the entry block.

    Add a local stack object block allocation pass. This is still an
    experimental pass that allocates locals relative to one another before
    register allocation and then assigns them to actual stack slots as a block
    later in PEI. This will eventually allow targets with limited index offset
    range to allocate additional base registers (not just FP and SP) to
    more efficiently reference locals, as well as handle situations where
    locals cannot be referenced via SP or FP at all (dynamic stack realignment
    together with variable sized objects, for example). It's currently
    incomplete and almost certainly buggy. Work in progress.

    Disabled by default and gated via the -enable-local-stack-alloc command
    line option.

    Implement hasComputableLoopEvolution for Add, Mul, and Trunc operators,
    since they can support trivial implementations. This avoids potentially
    expensive traversals of the operands.

    numbers match. The old check could accidentally leave holes in openli.

    Also let useIntv add all ranges for the phi-def value inserted by

    enterIntvAtEnd.

    Handle an empty dupli.

    This can happen if the original interval has been broken into two disconnected
    parts. Ideally, we should be able to detect when the graph is disconnected and
    create separate intervals, but that code is not implemented yet.

    Example:

    Two basic blocks are both branching to a loop header. Our interval is defined in
    both basic blocks, and live into the loop along both edges.

    We decide to split the interval around the loop. The interval is split into an
    inside part and an outside part. The outside part now has two disconnected
    segments, one in each basic block.

    If we later decide to split the outside interval into single blocks, we get one
    interval per basic block and an empty dupli for the remainder.

    - Teach SSEDomainFix to switch between different levels of AVX instructions. Here we guess that AVX will have domain issues, so just implement them for consistency  and in the future we remove if it's unnecessary.
    - Make foldMemoryOperandImpl aware of 256-bit zero vectors folding and support the 128-bit counterparts of AVX too.
    - Make sure MOV[AU]PS instructions are only selected when SSE1 is enabled, and duplicate the patterns to match AVX.

    Implement single block splitting.

    Before spilling a live range, we split it into a separate range for each basic
    block where it is used. That way we only get one reload per basic block if the
    new smaller ranges can allocate to a register.

    This type of splitting is already present in the standard spiller.

    Add a 'normalize' method to the Triple class, which takes a mucked up
    target triple and straightens it out.  This does less than gcc's script
    config.sub, for example it turns i386-mingw32 into i386--mingw32 not
    i386-pc-mingw32, but it does a decent job of turning funky triples into
    something that the rest of the Triple class can understand.  The plan
    is to use this to canonicalize triple's when they are first provided
    by users, and have the rest of LLVM only deal with canonical triples.
    Once this is done the special case workarounds in the Triple constructor
    can be removed, making the class more regular and easier to use.  The
    comments and unittests for the Triple class are already adjusted in this
    patch appropriately for this brave new world of increased uniformity.

    Begin to support some vector operations for AVX 256-bit intructions. The long
    term goal here is to be able to match enough of vector_shuffle and build_vector
    so all avx intrinsics which aren't mapped to their own built-ins but to
    shufflevector calls can be codegen'd. This is the first (baby) step, support
    building zeroed vectors.

    The autogened decoder was confusing the ARM STRBT for ARM USAT, because the .td
    entry for ARM STRBT is actually a super-instruction for A8.6.199 STRBT A1 & A2.
    Recover by looking for ARM:USAT encoding pattern before delegating to the auto-
    gened decoder.

    Added a "usat" test case to arm-tests.txt.

    Fix <rdar://problem/8282498> even if it doesn't reproduce on trunk.
    When a register is defined by a partial load:

      %reg1234:sub_32 = MOV32mr <fi#-1>; GR64:%reg1234

    That load cannot be folded into an instruction using the full 64-bit register.
    It would become a 64-bit load.

    This is related to the recent change to have isLoadFromStackSlot return false on
    a sub-register load.

    Use ISD::ADD instead of ISD::SUB with a negated constant. This
    avoids trouble if the return type of TD->getPointerSize() is

    Also, use getCopyFromReg instead of getRegister to read a

    platform. It's apparently "bl __muldf3" on linux, for example. Since that's

    just wwant to check that the inline FP instructions are only generated
    on cpus that have them."

    Consider this code snippet:

    float t1(int argc) {
      return (argc == 1123) ? 1.234f : 2.38213f;
    }

    We would generate truly awful code on ARM (those with a weak stomach should look
    away):

    _t1:
      movw   r1, #1123
      movs   r2, #1
      movs   r3, #0
      cmp    r0, r1
      mov.w  r0, #0
      it     eq
      moveq  r0, r2
      movs   r1, #4
      cmp    r0, #0
      it     ne
      movne  r3, r1
      adr    r0, #LCPI1_0
      ldr    r0, [r0, r3]
      bx     lr

    The problem was that legalization was creating a cascade of SELECT_CC nodes, for
    for the comparison of "argc == 1123" which was fed into a SELECT node for the ?:
    statement which was itself converted to a SELECT_CC node. This is because the
    ARM back-end doesn't have custom lowering for SELECT nodes, so it used the
    default "Expand".

    I added a fairly simple "LowerSELECT" to the ARM back-end. It takes care of this
    testcase, but can obviously be expanded to include more cases.

    Now we generate this, which looks optimal to me:

    _t1:
      movw   r1, #1123
      movs   r2, #0
      cmp    r0, r1
      adr    r0, #LCPI0_0
      it     eq
      moveq  r2, #4
      ldr    r0, [r0, r2]
      bx     lr
      .align  2
    LCPI0_0:
      .long   1075344593  @ float 2.382130e+00
      .long   1067316150  @ float 1.234000e+00

    Add AVX matching patterns to Packed Bit Test intrinsics.

    Apply the same approach of SSE4.1 ptest intrinsics but
    create a new x86 node "testp" since AVX introduces
    vtest{ps}{pd} instructions which set ZF and CF depending
    on sign bit AND and ANDN of packed floating-point sources.

    This is slightly different from what the "ptest" does.
    Tests comming with the other 256 intrinsics tests.

    Add the minimal amount of smarts necessary to instcombine of shufflevectors to recognize
    patterns generated by clang for transpose of a matrix in generic vectors.  This is made
    of two parts:

    1) Propagating vector extracts of hi/lo half into their users
    2) Recognizing an insertion of even elements followed by the odd elements as an unpack.

    Testcase to come, but this shrinks the # of shuffle instructions generated on x86 from ~40 to the minimal 8.

    The live interval may be used for a spill slot as well, and that spill slot
    could be shared by split registers. We cannot shrink it, even if we know the

    Re-apply r110655 with fixes. Epilogue must restore sp from fp if the function stack frame has a var-sized object.

    Also added a test case to check for the added benefit of this patch: it's optimizing away the unnecessary restore of sp from fp for some non-leaf functions.

    Implement register class inflation.

    When splitting a live range, the new registers have fewer uses and the
    permissible register class may be less constrained. Recompute the register class
    constraint from the uses of new registers created for a split. This may let them
    be allocated from a larger set, possibly avoiding a spill.

    Fix ARM hasFP() semantics. It should return true whenever FP register is
    reserved, not available for general allocation. This eliminates all the
    extra checks for Darwin.

    This change also fixes the use of FP to access frame indices in leaf
    functions and cleaned up some confusing code in epilogue emission.

    Transpose the calculation of spill weights such that we are calculating one
    register at a time. This turns out to be slightly faster than iterating over
    instructions, but more importantly, it allows us to compute spill weights for
    new registers created after the spill weight pass has run.

    Also compute the allocation hint at the same time as the spill weight. This
    allows us to use the spill weight as a cost metric for copies, and choose the
    most profitable hint if there is more than one possibility.

    The new hints provide a very small (< 0.1%) but universal code size improvement.

    ARMBaseRegisterInfo::hasFP() has been broken for a while now. :-(
    This will always be false before PEI:
    (DisableFramePointerElim(MF) && MFI->adjustsStack())
    Which means it's going to make r11 available as a general purpose register even

    Lazily defer duplicating the live interval we are splitting until we know it is
    necessary.

    Sometimes, live range splitting doesn't shrink the current interval, but simply
    changes some instructions to use a new interval. That makes the original more
    suitable for spilling. In this case, we don't need to duplicate the original.

    Don't try to verify LiveIntervals for physical registers.

    When a physical register is in use, some alias of that register has a live
    interval with a relevant live range. That is the sad state of intervals after
    physreg coalescing of subregs, and it is good enough for correct register
    allocation.

    Fix eabi calling convention when a 64 bit value shadows r3.

    Without this what was happening was:

    * R3 is not marked as "used"
    * ARM backend thinks it has to save it to the stack because of vaarg
    * Offset computation correctly ignores it
    * Offsets are wrong

    Add the Optimize Compares pass (disabled by default).

    This pass tries to remove comparison instructions when possible. For instance,
    if you have this code:

       sub r1, 1
       cmp r1, 0
       bz  L1

    and "sub" either sets the same flag as the "cmp" instruction or could be
    converted to set the same flag, then we can eliminate the "cmp" instruction all
    together. This is a important for ARM where the ALU instructions could set the
    CPSR flag, but need a special suffix ('s') to do so.

    Move all the logic for function attributes and call attributes out of the

    about where such logic is happening when there are other AliasAnalysis
    implementations present.

    Move the logic for translating two-callsite getModRefInfo queries into
    other AliasAnalysis queries out of BasicAliasAnalysis and into the
    AliasAnalysis base class, as it is useful for other AliasAnalysis
    implementations.

    - Are all live ranges continually reachable from their def?

    For local variables in functions with a frame pointer, use FP as a base
    register for local access when it's closer to the stack slot being refererenced
    than the stack pointer. Make sure to take into account any argument frame
    SP adjustments that are in affect at the time.

    Remove double-def checking from MachineVerifier, so a register does not have to
    be killed before being redefined.

    These checks are usually disabled, and usually fail when enabled. We de facto
    allow live registers to be redefined without a kill, the corresponding
    assertions in RegScavenger were removed long ago.

    Reserve a stack slot if the function adjusts the stack but doesn't
    simplify the call frame pseudo instructions. In that situation, the
    calculations for estimating the stack size will be way off, leading to
    not having an emergency spill slot when we need one. It should be possible
    to be more precise about tracking the adjustment values, but not really
    necessary for correctness. Upcoming cleanups for PEI in general will
    render that moot.

    Use indirect calls in PowerPC JIT.

    See PR5201. There is no way to know if direct calls will be within the allowed
    range for BL. Hence emit all calls as indirect when in JIT mode.
    Without this long-running applications will fail to JIT on PowerPC with a
    relocation failure.

    - The COFF backend doesn't support MingW/Cygwin at the moment, it'll report an

    - We want to make ELF the default eventually, it's what the majority of targets use.

    "The CWriter::GetValueName() method does not check if a value as an alias
    and emits the alias name which will never be defined in the output .c
    file (so the output file fails to compile). This can happen if you have
    multiple inheritance with several destructors defined by clang (...D0Ev,
    ...D1Ev, ...D2Ev)."

    OK, that's it. This test is going away now. But don't worry, I am taking it to a
    nice farm in the country where it can play with other tests. And bunnies.

    It is not clear what is being tested, and the revision history shows a bunch of
    random changes to the expected instruction count. Clearly, we are just fudging
    it to pass whenever it fails.

    Make SCEVUnknown a CallbackVH, so that it can be notified directly
    of Value deletions and RAUWs, instead of relying on ScalarEvolution's
    Scalars map being notified, as that's complicated at best, and
    insufficient in general.

    This means SCEVUnknown needs a non-trivial destructor, so introduce
    a mechanism to allow ScalarEvolution to locate all the SCEVUnknowns.

    Add preliminary v2i32 support for SPU backend. As there are no
    such registers in SPU, this support boils down to "emulating"
    them by duplicating instructions on the general purpose registers.

    This adds the most basic operations on v2i32: passing parameters,
    addition, subtraction, multiplication and a few others.

    There was also only one user of

    make BlockExtractorPass read BlockFile.

    Support all 128-bit AVX vector intrinsics. Most part of them I already
    declared during the addition of the assembler support, the additional
    changes are:
    - Add missing intrinsics
    - Move all SSE conversion instructions in X86InstInfo64.td to the SSE.td file.
    - Duplicate some patterns to AVX mode.
    - Step into PCMPEST/PCMPIST custom inserter and add AVX versions.

    Fix the ValueMap copy constructor.  The issue is that the map keys are value
    handles with a pointer to the containing map.  When a map is copied, these
    pointers need to be corrected to point to the new map.  If not, then consider
    the case of a map M1 which maps a value V to something.  Create a copy M2 of
    M1.  At this point there are two value handles on V, one representing V as a
    key in M1, the other representing V as a key in M2.  But both value handles
    point to M1 as the containing map.  Now delete V.  The value handles remove
    themselves from their containing map (which destroys them), but only the first
    value handle is successful: the second one cannot remove itself from M1 as
    (once the first one has removed itself) there is nothing there to remove; it
    is therefore not destroyed.  This causes an assertion failure "All references
    to V were not removed?".

commit ad94e9b576e5c94f507ecdf8f6d597fe2eebba86
Author: Jim Grosbach <grosbach@apple.com>
Date:   Fri Jul 30 02:41:01 2010 +0000

    Many Thumb2 instructions can reference the full ARM register set (i.e.,
    have 4 bits per register in the operand encoding), but have undefined
    behavior when the operand value is 13 or 15 (SP and PC, respectively).
    The trivial coalescer in linear scan sometimes will merge a copy from
    SP into a subsequent instruction which uses the copy, and if that
    instruction cannot legally reference SP, we get bad code such as:
      mls r0,r9,r0,sp
    instead of:
      mov r2, sp
      mls r0, r9, r0, r2

    This patch adds a new register class for use by Thumb2 that excludes
    the problematic registers (SP and PC) and is used instead of GPR
    for those operands which cannot legally reference PC or SP. The
    trivial coalescer explicitly requires that the register class
    of the destination for the COPY instruction contain the source
    register for the COPY to be considered for coalescing. This prevents
    errant instructions like that above.

    Revert r109652, and remove the offending assert in loadRegFromStackSlot instead.

    We do sometimes load from a too small stack slot when dealing with x86 arguments
    (varargs and smaller-than-32-bit args). It looks like we know what we are doing
    in those cases, so I am going to remove the assert instead of artifically
    enlarging stack slot sizes.

    The assert in storeRegToStackSlot stays in. We don't want to write beyond the
    bounds of a stack slot.

    Centralize the logic to permanently unify two instructions and make sure
    it establishes a context and does a complaining diff.  Also make sure we
    unify the prelude and postlude of a diff after a block-diff call.

    When unifying instructions during a block diff, actually complain about
    any differences we see.  This should only happen if there are "non-structural"
    differences between the instructions, i.e. differences which wouldn't cause
    diff to return true.

    Somehow I was getting reasonable results for the test cases I was interested
    in despite not ever incrementing any path costs, so that the only nonzero costs
    arose from the all-left path in the first column.  Anyway.  Perform the diff
    starting from the beginning of the block to avoid capturing (say) loads of
    allocas.

    Vastly improves diff results on code that hasn't been mem2reg'ed.

    Add the llvm-diff tool, which performs a relatively naive structural
    diff of a function.  There's a lot of cruft in the current version, and
    it's pretty far from perfect, but it's usable.

    Currently only capable of comparing functions.  Currently ignores metadata.
    Currently ignores most attributes of functions and instructions.

    Patches welcome.

    CrashRecoveryContext: Add a simple POSIX implementation.
     - This works, but won't handle crashes on stack overflow, or signals delivered
       to a thread other than the one that crashed. The latter is particular annoying

    Fix a bug in the -regalloc=fast handling of exotic two-address instruction with
    multiple defs, like t2LDRSB_POST.

    The first def could accidentally steal the physreg that the second, tied def was
    required to be allocated to.

    Now, the tied use-def is treated more like an early clobber, and the physreg is
    reserved before allocating the other defs.

    This would never be a problem when the tied def was the only def which is the
    usual case.

    This fixes MallocBench/gs for thumb2 -O0.

    Make SCEVCallbackVH::allUsesReplacedWith update the old SCEVUnknown
    object, as it may still be referenced by SCEVs not cleaned up by the
    use list traversal.

    Also, in ScalarEvolution::forgetValue, only check for a SCEVUnknown
    object for the original value, not for any value in the use list,
    because other SCEVUnknown values aren't necessary obsolete at that
    point.

    ~40% faster vector shl <4 x i32> on SSE 4.1  Larger improvements for smaller types coming in future patches.

    For:

    define <2 x i64> @shl(<4 x i32> %r, <4 x i32> %a) nounwind readnone ssp {
    entry:
      %shl = shl <4 x i32> %r, %a                     ; <<4 x i32>> [#uses=1]
      %tmp2 = bitcast <4 x i32> %shl to <2 x i64>     ; <<2 x i64>> [#uses=1]
      ret <2 x i64> %tmp2
    }

    We get:

    _shl:                                   ## @shl
    	pslld	$23, %xmm1

    	cvttps2dq	%xmm1, %xmm1
    	pmulld	%xmm1, %xmm0
    	ret

    Instead of:

    _shl:                                   ## @shl
    	pshufd	$3, %xmm0, %xmm2

    The isLoadFromStackSlot and isStoreToStackSlot have no way of reporting
    subregister operands like this:

    %reg1040:sub_32bit<def> = MOV32rm <fi#-2>, 1, %reg0, 0, %reg0, %reg1040<imp-def>; mem:LD4[FixedStack-2](align=8)

    Make them return false when subreg operands are present. VirtRegRewriter is
    making bad assumptions otherwise.

    This fixes PR7713.

    It's better to have the arrays, which would trigger the creation of stack
    protectors, to be near the stack protectors on the stack. Accomplish this by
    tagging the stack object with a predicate that indicates that it would trigger
    this. In the prolog-epilog inserter, assign these objects to the stack after the
    stack protector but before the other objects.

    Temporary hack to let codegen assert or generate poor code in case
    we are using AVX and no AVX version of the desired intruction is present,
    this is better for incremental dev (without fallbacks it's easier to spot
    what's missing). Not sure this is the best hack thought (we can also disable
    all HasSSE* predicates by dinamically marking them 'false' if AVX is present)

    re-commit r109220, the compile error has already been fixed

    Simplifying use_iterators by dereferencing
    is not a good idea. The codebase does not depend
    in this any more, and it may introduce hidden
    runtime cost. If you get compile errors, please
    dereference your iterator before passing to cast<>
    (and friends).

    Also: please consider caching the result of
    operator* and reusing that instead of dereferencing
    many times.

    Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock:
    don't visit all blocks in the function, and don't iterate over the split blocks'
    predecessor lists for each block visited.

    Also, remove the special-case test for the entry block. Splitting the entry
    block isn't common enough to make this worthwhile.

    This fixes a major compile-time bottleneck which is exposed now that
    LoopSimplify isn't being redundantly run both before and after
    DominanceFrontier.

    Clone and restore the module being reduced in
    ReduceMiscompilingFunctions::TestFuncs. This makes the test functional
    (i.e., no side effects).

    Before we would end up using dead functions if a pass decided to remove them
    (inline for example) and we would also keep broken functions and conclude that
    that a single function was enough to reproduce the bug.

    Add an ILP scheduler. This is a register pressure aware scheduler that's
    appropriate for targets without detailed instruction iterineries.
    The scheduler schedules for increased instruction level parallelism in
    low register pressure situation; it schedules to reduce register pressure
    when the register pressure becomes high.

    On x86_64, this is a win for all tests in CFP2000. It also sped up 256.bzip2
    by 16%.

    - Allow target to specify when is register pressure "too high". In most cases,
      it's too late to start backing off aggressive latency scheduling when most
      of the registers are in use so the threshold should be a bit tighter.
    - Correctly handle live out's and extract_subreg etc.
    - Enable register pressure aware scheduling by default for hybrid scheduler.
      For ARM, this is almost always a win on # of instructions. It's runtime
      neutral for most of the tests. But for some kernels with high register
      pressure it can be a huge win. e.g. 464.h264ref reduced number of spills by
      54 and sped up by 20%.

    Simplifying use_iterators by dereferencing
    is not a good idea. The codebase does not depend
    in this any more, and it may introduce hidden
    runtime cost. If you get compile errors, please
    dereference your iterator before passing to cast<>
    (and friends).

    Also: please consider caching the result of
    operator* and reusing that instead of dereferencing
    many times.

    give StringMap a new ctor which allows you to initialize it
    with an existing allocator.  The interesting use case of this
    is that it allows "StringMap<whatever, BumpPtrAllocator&>" for
    when you want to allocate out of a preexisting bump pointer
    allocator owned by someone else.

    The only supported calling convention for X86-64 uses
    SSE, so we can't return floating point values if this
    is disabled.  Detect this error for clang.

    With SSE1 only, f64 is a problem; it can be done, but
    neither llvm-gcc nor clang has ever generated correct
    code for it.  Since nobody noticed this I think it's
    OK to treat it as an error for now.

    This also handles SSE-sized vectors of floating point.

    instead of migrating it to the MC instruction encoder, just
    rip out the implementation of X86InstrInfo::GetInstSizeInBytes.
    The code being ripped out just implemented a copy and hacked up
    version of the (old) instruction encoder, and is buggy and
    terrible in other ways.  Since "GetInstSizeInBytes" is really
    only there to support the JIT's "NeedsExactSize" hook (which
    noone is using), just rip out the code.  I will rip out the
    NeedsExactSize hook next.

    This resolves rdar://7617809 - switch X86InstrInfo::GetInstSizeInBytes to use X86MCCodeEmitter

    Add new RegionInfo pass.

    The RegionInfo pass detects single entry single exit regions in a function,
    where a region is defined as any subgraph that is connected to the remaining
    graph at only two spots.
    Furthermore an hierarchical region tree is built.
    Use it by calling "opt -regions analyze" or "opt -view-regions".

    Fix constant island pass's handling of tBR_JTr. The offset of the instruction does not have to be 4-byte aligned. Rather, it's the offset + 2 that must be aligned since the instruction expands into:
            mov     pc, r1
            .align  2
    LJTI0_0_0:
            .long    LBB0_14

    Fix a couple issues with Win64 ABI

    1) all registers were spilled as xmm, regardless of actual size
    2) win64 abi doesn't do the varargs-size-in-%al thing

    Still to look into:

    xmm6-15 are marked as clobbered by call instructions on win64 even though they aren't.

    Disallow null as a named metadata operand.
    Make MDNode::destroy private.
    Fix the one thing that used MDNode::destroy, outside of MDNode itself.

    One should never delete or destroy an MDNode explicitly. MDNodes
    implicitly go away when there are no references to them (implementation
    details aside).

    Add support for remapping metadata kind IDs when reading in a
    bitcode file, so that two bitcode files where the same metadata kind
    name happens to have been assigned a different ID can still be
    linked together.

    Eliminate the restriction that metadata kind IDs can't be 0.

    Change MD_dbg from 1 to 0, because we can now, and because it's
    less mysterious that way.

    there is now no reason to link in TARGETS_TO_BUILD since we list
    arm explicitly.  X86 and ARM are the only two targets that support
    disassembly, so our explicit list is enough.  These other targets
    weren't getting pulled in anyway though, since there were no
    references to their symbols.

    start straightening out libedis's dependencies and make it fit
    better in the llvm world.  Among other things, this changes:

    1. The guts of libedis are now moved into lib/MC/MCDisassembler
    2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
       so edis and mc don't have to be built in series.
    3. lib/MC/MCDisassembler no longer depends on the C api, the C
       API depends on it.
    4. Various code cleanup changes.

    There is still a lot to be done to make edis fit with the llvm
    design, but this is an incremental step in the right direction.

    Beginning SplitKit - utility classes for live range splitting.

    This is a work in progress. So far we have some basic loop analysis to help
    determine where it is useful to split a live range around a loop.

    The actual loop splitting code from Splitter.cpp is also going to move in here.

    Change the implemented interfaces list on PassInfo from a std::vector to a manually implemented

Author: Evan Cheng <evan.cheng@apple.com>
Date:   Mon Jul 19 18:47:01 2010 +0000

    Teach computeRegisterProperties() to compute "representative" register class for legal value types. A "representative" register class is the largest legal super-reg register class for a value type. e.g. On i386, GR32 is the rep register class for i8 / i16 / i32; on x86_64 it would be GR64.

    This property will be used by the register pressure tracking instruction scheduler.

    Iterating over sets of pointers in a heuristic was a bad idea. Switching
    any command line paramater changed the register allocation produced by
    PBQP.

    Consider this function:

      void foo() { __builtin_unreachable(); }

    It will output the following on Darwin X86:

    _func1:
    Leh_func_begin0:
            pushq %rbp
    Ltmp0:
            movq %rsp, %rbp
    Ltmp1:
    Leh_func_end0:

    This prolog adds a new Call Frame Information (CFI) row to the FDE with an
    address that is not within the address range of the code it describes -- part is
    equal to the end of the function -- and therefore results in an invalid EH
    frame. If we emit a nop in this situation, then the CFI row is now within the
    address range.

    Revert r108369, sorting llvm.dbg.declare information by source position,
    since it doesn't work for front-ends which don't emit column information
    (which includes llvm-gcc in its present configuration), and doesn't
    work for clang for K&R style variables where the variables are declared
    in a different order from the parameter list.

    Instead, make a separate pass through the instructions to collect the
    llvm.dbg.declare instructions in order. This ensures that the debug
    information for variables is emitted in this order.

    Allow x87 FP registers to be alive globally in a function.

    FP_REG_KILL instructions are still inserted, but can be disabled by passing
    -live-x87 to llc. The X87FPRegKillInserterPass is going to be removed shortly.

    CFG edges are partioned into bundles where the x87 stack must be allocated
    identically. Code is insertad at the end of each basic block that shuffles the
    live FP registers to match the outgoing bundles expectations.

    This fix is in preparation for some upcoming register allocator improvements
    that may extend the live range of registers beyond a basic block, similar to
    LICM. It also provides a nice runtime speedup if you are building with
    -mfpmath=387.

    Handle code gen for the unreachable instruction if it's the only instruction in
    the function. We'll just turn it into a "trap" instruction instead.

    The problem with not handling this is that it might generate a prologue without
    the equivalent epilogue to go with it:

    $ cat t.ll
    define void @foo() {
    entry:
      unreachable
    }
    $ llc -o - t.ll -relocation-model=pic -disable-fp-elim -unwind-tables
            .section        __TEXT,__text,regular,pure_instructions
            .globl  _foo
            .align  4, 0x90
    _foo:                                   ## @foo
    Leh_func_begin0:
    ## BB#0:                                ## %entry
            pushq   %rbp
    Ltmp0:
            movq    %rsp, %rbp
    Ltmp1:
    Leh_func_end0:
    ...

    The unwind tables then have bad data in them causing all sorts of problems.

    fix the definitions of ConstTextCoalSection/ConstDataCoalSection
    to keep "Text" in sync with the "pure instructions" section attribute.
    Lack of this attribute was preventing the assembler from emitting
    multibyte noops instructions for templates (and inlines, and other
    coalesced stuff) and was causing the assembler to mismatch .o files.

    This fixes rdar://8018335

    Don't merge uses when they are targetting fixup sites with
    different widths. In a use with a narrower fixup, formulae
    may be wider than the fixup, in which case the high bits
    aren't necessarily meaningful, so it isn't safe to reuse
    them for uses with wider fixups.

    This fixes PR7618, though the testcase is too large for a
    reasonable regression test, since it heavily dependes on
    hitting LSR's heuristics in a certain way.

    Per Chris' suggestion, get rid of the select canonicalization and just add
    the corresponding or-icmp-and pattern.  This has the added benefit of doing
    the matching earlier, and thus being less susceptible to being confused by

    Correctly set rpath on Mac OS X for executable tools.  Note that I am not certain this is the best fix; the code immediately above looks confused, as it first checks to see if we are NOT on Darwin and then checks the Darwin version number.  This fix allows c-index-test (in Clang) to run outside of running the regression test suite.  I would appreciate if someone reviewed this.

    Fix PR7647, handling the case when 'To' ends up being
    mutated by recursive simplification.  This also enhances
    ReplaceAndSimplifyAllUses to actually do a real RAUW
    at the end of it, which updates any value handles
    pointing to "From" to start pointing to "To".  This
    seems useful for debug info and random other VH users.

    Use TargetOpcode::COPY instead of X86-native register copy instructions when
    lowering atomics. This will allow those copies to still be coalesced after
    TII::isMoveInstr is removed.

    Remove some broken code to check the DISABLE_EDIS flag (edis is now in the
    DIRS list, so it does no good to filter it from PARALLEL_DIRS), and replace
    it with a check to disable building the shared library version of edis when
    the flag is set.  Disabling it entirely does not work because MC uses it now.

    Extend SimplifyCFG's common-destination folding heuristic to allow a single
    "bonus" instruction to be speculatively executed.  Add a heuristic to
    ensure we're not tripping up out-of-order execution by checking that this bonus
    instruction only uses values that were already guaranteed to be available.

    This allows us to eliminate the short circuit in (x&1)&&(x&2).

    Fix for PR7193 was overly conservative. The only case where sibcall callee
    address cannot be allocated a register is in 32-bit mode where the first

    used for argument passing.

    Add an assertion to make PR7542 fail consistently.

    LiveInterval::overlapsFrom dereferences end() if it is called on an empty
    interval.

    It would be reasonable to just return false - an empty interval doesn't overlap
    anything, but I want to know who is doing it first.

    Handle the case of a tail recursion in which the tail call is followed
    by a return that returns a constant, while elsewhere in the function
    another return instruction returns a different constant.  This is a
    special case of accumulator recursion, so just generalize the existing
    logic a bit.

    rotate CallInst operands

    with this commit the callee moves to the end of
    the operand array (from the start) and the call
    arguments now start at index 0 (formerly 1)

    this ordering is now consistent with InvokeInst

    this commit only flips the switch,
    functionally it is equivalent to
    r101465

    Convert the last use of getPhysicalRegisterRegClass and remove it.

    AggressiveAntiDepBreaker should not be using getPhysicalRegisterRegClass. An
    instruction might be using a register that can only be replaced with one from
    a subclass of getPhysicalRegisterRegClass.

    With this patch we use getMinimalPhysRegClass. This is correct, but
    conservative. We should check the uses of the register and select the
    largest register class that can be used in all of them.

    Don't use getPhysicalRegisterRegClass in PBQP. The existing checks that the
    physical register can be allocated in the class of the virtual are sufficient.

    I think that the test for virtual registers is more strict than it needs to be,
    it should be possible to coalesce two virtual registers the class of one
    is a subclass of the other.

    RISC architectures get their memory operand folding for free.

    The only folding these load/store architectures can do is converting COPY into a
    load or store, and the target independent part of foldMemoryOperand already

    Remove obsolete README_SSE note.

    We are generating movaps for all XMM register copies, including scalar
    floating point values. This is known to be at least as good as movss and movsd
    for all known architectures up to and including Nehalem because it avoids a
    partial register stall.

    The SSEDomainFix pass will switch movaps to movdqa when appropriate (i.e., when
    operands come from the integer unit). We don't now that switching movaps to
    movapd has any benefit.

    The same applies to andps -> pand.

    Convert uses of getPhysicalRegisterRegClass in VirtRegRewriter.cpp.

    The first one was used just to call isSafeToMoveRegClassDefs. In
    general, using a more specific reg class is better, in practice only
    x86 implements that method and the results are always the same.

    The second one is in FindFreeRegister and is used to check if a register
    is in a register class, a much more direct call to contains is better as
    it should cover more cases and is faster.

    Fix va_arg for doubles. With this patch VAARG nodes always contain the
    correct alignment information, which simplifies ExpandRes_VAARG a bit.

    The patch introduces a new alignment information to TargetLoweringInfo. This is
    needed since the two natural candidates cannot be used:

    * The 's' in target data: If this is set to the minimal alignment of any
      argument, getCallFrameTypeAlignment would return 4 for doubles on ARM for
      example.
    * The getTransientStackAlignment method. It is possible for an architecture to
      have argument less aligned than what we maintain the stack pointer.

    The accumulator tail recursion transform claims to work for any associative
    operation, but the way it's implemented requires the operation to also be
    commutative.  So add a check for commutativity (and tweak the corresponding
    comments).  This makes no difference in practice since every associative
    LLVM instruction is also commutative!  Here's an example to show the need
    for commutativity: the accum_recursion.ll testcase calculates the factorial
    function.  Before the transformation the result of a call is
      ((((1*1)*2)*3)...)*x
    while afterwards it is
      (((1*x)*(x-1))...*2)*1
    which clearly requires both associativity and commutativity of * to be equal
    to the original.

    Don't emit st(0)/st(1) copies as FpMOV instructions. Use FpSET_ST? instead.

    Based on a patch by Rafael Espíndola.

    Attempt to make the FpSET_ST1 hack more robust, but we are still relying on
    FpSET_ST0 preceeding it. This is only for supporting really weird x87 inline
    asm.

    We support:

      FpSET_ST0
      INLINEASM

      FpSET_ST0
      FpSET_ST1
      INLINEASM

    with and without kills on the arguments. We don't support:

    An x86 function returns a floating point value in st(0), and we must make sure
    it is popped, even if it is ununsed. A CopyFromReg node is too weak to represent
    the required sideeffect, so insert an FpGET_ST0 instruction directly instead.

    This will matter when CopyFromReg gets lowered to a generic COPY instruction.

    Start the support for AVX instructions with 256-bit %ymm registers. A couple of
    notes:
    - The instructions are being added with dummy placeholder patterns using some 256
      specifiers, this is not meant to work now, but since there are some multiclasses
      generic enough to accept them,  when we go for codegen, the stuff will be already
      there.
    - Add VEX encoding bits to support YMM
    - Add MOVUPS and MOVAPS in the first round
    - Use "Y" as suffix for those Instructions: MOVUPSYrr, ...
    - All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX
      file.

    Change TII::foldMemoryOperand API to require the machine instruction to be
    inserted in a MBB, and return an already inserted MI.

    This target API change is necessary to allow foldMemoryOperand to call
    storeToStackSlot and loadFromStackSlot when folding a COPY to a stack slot
    reference in a target independent way.

    The foldMemoryOperandImpl hook is going to change in the same way, but I'll wait
    until COPY folding is actually implemented. Most targets only fold copies and
    won't need to specialize this hook at all.

    Added a support for inserting new MBBs into the numbering.

    Unlike insertMachineInstrInMaps this does not guarantee live intervals will
    remain correct. The caller will need to manually update intervals to account
    for the changes made to the CFG.

    have the mc lowering process handle a few tail call forms, lowering them to
    jumps where possible and turning the TAILCALL marker in the instruction
    asm string into a proper comment.

    This eliminates a FIXME and is on the path to finishing:
    rdar://7639610 - eliminate encoding and asm info for TAILJMPd TAILJMPr TAILJMPn, etc.

    However, I can't eliminate the encodings for these instructions because the JIT
    still exists and has its own copy of the encoder, sigh.

    Reenable DAG combining for vector shuffles.  It looks like it was temporarily

    Change LEA to have 5 operands for its memory operand, just
    like all other instructions, even though a segment is not
    allowed.  This resolves a bunch of gross hacks in the
    encoder and makes LEA more consistent with the rest of the
    instruction set.

    No functionality change.

    Teach the x86 floating point stackifier to handle COPY instructions.

    This pass runs before COPY instructions are passed to copyPhysReg, so we simply
    translate COPY to the proper pseudo instruction. Note that copyPhysReg does not
    handle floating point stack copies.

    Once COPY is used everywhere, this can be cleaned up a bit, and most of the
    pseudo instructions can be removed.

    Optimize some vfp comparisons to integer ones. This patch implements the simplest case when the following conditions are met:
    1. The arguments are f32.
    2. The arguments are loads and they have no uses other than the comparison.
    3. The comparison code is EQ or NE.

    e.g.
            vldr.32 s0, [r1]
            vldr.32 s1, [r0]
            vcmpe.f32       s1, s0

    When processing frame index virtual registers, consider all available registers
    (if there are any) and use the one which remains available for the longest
    rather than just using the first one. This should help enable better re-use
    of the loaded frame index values. rdar://7318760

    Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts"
    builds to "Release".  The default build is unchanged (optimization on,
    assertions on), however it is now called Release+Asserts.  The intent
    is that future LLVM releases released via llvm.org will be Release builds
    in the new sense, i.e. will have assertions disabled (currently they have
    assertions enabled, for a more than 20% slowdown).  This will bring them
    in line with MacOS releases, which ship with assertions disabled.  It also
    means that "Release" now means the same things in make and cmake builds:
    cmake already disables assertions for "Release" builds AFAICS.

    Be more forgiving when calculating alias interference for physreg coalescing.

    It is OK for an alias live range to overlap if there is a copy to or from the
    physical register. CoalescerPair can work out if the copy is coalescable
    independently of the alias.

    This means that we can join with the actual destination interval instead of
    using the getOrigDstReg() hack. It is no longer necessary to merge clobber
    ranges into subregisters.

    second round of low-level interface squeeze-out:
    making all of CallInst's low-level operand accessors
    private

    If you get compile errors I strongly urge you to
    update your code.

    I tried to write the necessary clues into the
    header where the compiler may point to, but no
    guarantees. It works for my GCC.

    You have several options to update your code:

    - you can use the v2.8 ArgOperand accessors
    - you can go via a temporary CallSite
    - you can upcast to, say, User and call its
      low-level accessors if your code is definitely
      operand-order agnostic.

    If you run into serious problems, please
    comment in below thread (and back out this
    revision only if absolutely necessary):

    Fix a major regression on COFF targets introduced by r103267: 'discardable' section means that it is used only during the program load and can be discarded afterwards.
    This way *only* debug sections can be discarded, but not the opposite. Seems like the copy-and-pasto from ELF code, since there it contains the reverse flag ('alloc').

    Just rip v2f32 support completely out of the X86 backend.  In
    the example in the testcase, we now generate:

    _test1:                                 ## @test1
    	movss	4(%esp), %xmm0
    	addss	8(%esp), %xmm0
    	movl	12(%esp), %eax
    	movss	%xmm0, (%eax)
    	ret

    instead of:

    _test1:                                                     ## @test1
    	subl	$20, %esp
    	movl	24(%esp), %eax
    	movq	%mm0, (%esp)
    	movq	%mm0, 8(%esp)
    	movss	(%esp), %xmm0
    	addss	12(%esp), %xmm0
    	movss	%xmm0, (%eax)
    	addl	$20, %esp
    	ret

    v2f32 support did not work reliably because most of the X86
    backend didn't know it was legal.  It was apparently only added
    to support returning source-level v2f32 values in MMX registers
    in x86-32 mode.  If ABI compatibility is important on this
    GCC-extended-vector type for some reason, then the frontend
    should generate IR that returns v2i32 instead of v2f32.  However,
    we generally don't try very hard to be abi compatible on gcc
    extended vectors.

    Add a new target independent COPY instruction and code to lower it.

    The COPY instruction is intended to replace the target specific copy
    instructions for virtual registers as well as the EXTRACT_SUBREG and
    INSERT_SUBREG instructions in MachineFunctions. It won't we used in a selection
    DAG.

    COPY is lowered to native register copies by LowerSubregs.

    Custom inserters (e.g., conditional moves in Thumb1 can introduce
    new basic blocks, and if used as a function argument, that can cause call frame
    setup / destroy pairs to be split across a basic block boundary. That prevents
    us from doing a simple assertion to check that the pairs match and alloc/
    dealloc the same amount of space. Modify the assertion to only check the
    amount allocated when there are matching pairs in the same basic block.

    - Two-address pass should not assume unfolding is always successful.
    - X86 unfolding should check if the instructions being unfolded has memoperands.
      If there is no memoperands, then it must assume conservative alignment. If this
      would introduce an expensive sse unaligned load / store, then unfoldMemoryOperand
      etc. should not unfold the instruction.

    Propagate the AlignStack bit in InlineAsm's to the
    PrologEpilog code, and use it to determine whether
    the asm forces stack alignment or not.  gcc consistently
    does not do this for GCC-style asms; Apple gcc inconsistently
    sometimes does it for asm blocks.  There is no
    convenient place to put a bit in either the SDNode or
    the MachineInstr form, so I've added an extra operand
    to each; unlovely, but it does allow for expansion for
    more bits, should we need it.  PR 5125.  Some
    existing testcases are affected.
    The operand lists of the SDNode and MachineInstr forms
    are indexed with awesome mnemonics, like "2"; I may
    fix this someday, but not now.  I'm not making it any
    worse.  If anyone is inspired I think you can find all
    the right places from this patch.

    Reword the definition of the noalias attribute. The intention is for
    the noalias argument on function attributes be usable to model the
    C99 restrict keyword on arguments, and to allow AliasAnalysis to
    consider a noalias-attributed argument to be an "identified object".

    To support this, refactor a new "based on" concept out of the current
    pointer aliasing "associated" concept. This "based on" concept is very
    similar to (though it is not identical with) the "based on" concept
    in C99.

    Also, reword the definition of NoAlias to more closely describe the
    concept that the optimizer uses.

    Rematerialize as much as possible before inserting spills and reloads.

    This allows us to recognize the common case where all uses could be
    rematerialized, and no stack slot allocation is necessary.

    If some values could be fully rematerialized, remove them from the live range
    before allocating a stack slot for the rest.

    [test commit, just to tickle the selfhost buildbots; I'll back out in a few minutes]

    second round of low-level interface squeeze-out:
    making all of CallInst's low-level operand accessors
    private

    If you get compile errors I strongly urge you to
    update your code.

    I tried to write the necessary clues into the
    header where the compiler may point to, but no
    guarantees. It works for my GCC.

    You have several options to update your code:

    - you can use the v2.8 ArgOperand accessors
    - you can go via a temporary CallSite
    - you can upcast to, say, User and call its
      low-level accessors if your code is definitely
      operand-order agnostic.

    If you run into serious problems, please
    comment in below thread (and back out this
    revision only if absolutely necessary):

commit 70d8fcc0e3aa3e0664de362b22198fd61b2fe11a
Author: Bill Wendling <isanbard@gmail.com>
Date:   Thu Jul 1 21:55:59 2010 +0000

    Implement the "linker_private_weak" linkage type. This will be used for
    Objective-C metadata types which should be marked as "weak", but which the
    linker will remove upon final linkage. However, this linkage isn't specific to
    Objective-C.

    For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:

          .globl l_objc_msgSend_fixup_alloc
          .weak_definition l_objc_msgSend_fixup_alloc
          .section __DATA, __objc_msgrefs, coalesced
          .align 3
    l_objc_msgSend_fixup_alloc:
           .quad   _objc_msgSend_fixup
           .quad   L_OBJC_METH_VAR_NAME_1

    This is different from the "linker_private" linkage type, because it can't have
    the metadata defined with ".weak_definition".

    Currently only supported on Darwin platforms.

    evil hack to coerce external users (projects)
    to update their code to high-level interfaces

    If you get compile errors in your project
    please update your code according to the
    comments.

    This is a re-commit of r107396 which causes
    compile errors for the indicated usage patterns
    instead of link errors (which are less easy to
    fix because of missing source location).

    If you get compile errors please perform
    following functionally equivalent transformations:
      - getOperand(0)  --->  getCalledValue()
      - setOperand(0, V)  --->  setCalledFunction(V)

    This will make your code more future-proof
    and avoid potentially hard-to-debug bugs.

    please refer to this thread on llvm-dev:

    In ScalarEvolution::forgetValue, eliminate any SCEVUnknown
    entries associated with the value being erased in the
    folding set map.  These entries used to be harmless, because
    a SCEVUnknown doesn't store any information about its Value*,
    so having a new Value allocated at the old Value's address
    wasn't a problem. But now that ScalarEvolution is storing more
    information about values, this is no longer safe.

    Remember to track spill slot uses in VirtRegMap when inserting loads and stores.
    LocalRewriter::runOnMachineFunction uses this information to mark dead spill
    slots.

    This means that InlineSpiller now also works for functions that spill.

    Rather than giving SmallPtrSetImpl a member field SmallArray which is magically
    replaced by a bigger array in SmallPtrSet (by overridding it), instead just use a
    pointer to the start of the storage, and have SmallPtrSet pass in the value to use.
    This has the disadvantage that SmallPtrSet becomes bigger by one pointer.  It has
    the advantage that it no longer uses tricky C++ rules, and is clearly correct while
    I'm not sure the previous version was.  This was inspired by g++-4.6 pointing out
    that SmallPtrSetImpl was writing off the end of SmallArray, which it was.  Since
    SmallArray is replaced with a bigger array in SmallPtrSet, the write was still to
    valid memory.  But it was writing off the end of the declared array type - sounds
    kind of dubious to me, like it sounded dubious to g++-4.6.  Maybe g++-4.6 is wrong
    and this construct is perfectly valid and correctly compiled by all compilers, but
    I think it is better to avoid the whole can of worms by avoiding this construct.

    Begin implementation of an inline spiller.

    InlineSpiller inserts loads and spills immediately instead of deferring to
    VirtRegMap. This is possible now because SlotIndexes allows instructions to be
    inserted and renumbered.

    This is work in progress, and is mostly a copy of TrivialSpiller so far. It
    works very well for functions that don't require spilling.

    Introducing the "linker_weak" linkage type. This will be used for Objective-C
    metadata types which should be marked as "weak", but which the linker will
    remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
    defined like this:

           .globl l_objc_msgSend_fixup_alloc
           .weak_definition l_objc_msgSend_fixup_alloc
           .section __DATA, __objc_msgrefs, coalesced
           .align 3
    l_objc_msgSend_fixup_alloc:
            .quad   _objc_msgSend_fixup
            .quad   L_OBJC_METH_VAR_NAME_1

    This is different from the "linker_private" linkage type, because it can't have
    the metadata defined with ".weak_definition".

    Fix a buffer overflow noticed by gcc-4.6: zero is written into
    SmallArray[SmallSize] in the SmallPtrSetIteratorImpl, and this is
    one off the end of the array.  For those who care, right now gcc
    warns about writing off the end because it is confused about the
    declaration of SmallArray as having length 1 in the parent class
    SmallPtrSetIteratorImpl.  However if you tweak code to unconfuse
    it, then it still warns about writing off the end of the array,
    because of this buffer overflow.  In short, even with this fix
    gcc-4.6 will warn about writing off the end of the array, but now
    that is only because it is confused.

    give PATypeHolder an explicit copy ctor which initializes the type pointer,
    and make PATypeHolder work with null pointers.

    The implicitly generated one didn't work on numerous levels, but was still
    accepted, allowing all sorts of bugs with default constructed pa type holders.

    Previously, they "sort of" worked if they were default constructed and then
    destructed.  Now they really work, and you can even default construct one,
    then assign to it, amazing.

    Fix the handling of partial redefines in the fast register allocator.

    A partial redefine needs to be treated like a tied operand, and the register
    must be reloaded while processing use operands.

    This fixes a bug where partially redefined registers were processed as normal
    defs with a reload added. The reload could clobber another use operand if it was
    a kill that allowed register reuse.

    in terms of Op<> and ArgOffset. This works for
    values of {0, 1} for ArgOffset.
    Please note that ArgOffset will become 0 soon and
    will go away eventually.

    Reapply my if-conversion cleanup from svn r106939 with fixes.
    There are 2 changes relative to the previous version of the patch:

    1) For the "simple" if-conversion case, there's no need to worry about
    RemoveExtraEdges not handling an unanalyzable branch.  Predicated terminators
    are ignored in this context, so RemoveExtraEdges does the right thing.
    This might break someday if we ever treat indirect branches (BRIND) as
    predicable, but for now, I just removed this part of the patch, because
    in the case where we do not add an unconditional branch, we rely on keeping
    the fall-through edge to CvtBBI (which is empty after this transformation).

    The change relative to the previous patch is:

    @@ -1036,10 +1036,6 @@
         IterIfcvt = false;

    -  // RemoveExtraEdges won't work if the block has an unanalyzable branch,

    -  BBI.BB->removeSuccessor(CvtBBI->BB);
       RemoveExtraEdges(BBI);

       // Update block info. BB can be iteratively if-converted.

    2) My patch exposed a bug in the code for merging the tail of a "diamond",
    which had previously never been exercised.  The code was simply checking that
    the tail had a single predecessor, but there was a case in
    MultiSource/Benchmarks/VersaBench/dbms where that single predecessor was
    neither edge of the diamond.  I added the following change to check for
    that:

    With these fixes, I was able to run all the SingleSource and MultiSource
    tests successfully.

    Clean up some problems with extra CFG edges being introduced during
    if-conversion.  The RemoveExtraEdges function doesn't work for blocks that
    end with unanalyzable branches, so in those cases, the "extra" edges must
    be explicitly removed.  The CopyAndPredicateBlock and MergeBlocks methods
    can also avoid copying successor edges due to branches that have already
    been removed.  The latter case is especially helpful when MergeBlocks is
    called for handling "diamond" if-conversions, where otherwise you can end
    up with some weird intermediate states in the CFG.  Unfortunately I've
    been unable to find cases where this cleanup actually makes a significant
    difference in the code.  There is one test where we manage to remove an
    empty block at the end of a function.  Radar 6911268.

    When creating X86 MUL8 and DIV8 instructions, make sure we don't produce
    CopyFromReg nodes for aliasing registers (AX and AL). This confuses the fast
    register allocator.

    Instead of CopyFromReg(AL), use ExtractSubReg(CopyFromReg(AX), sub_8bit).

    This fixes PR7312.

    Thumb2ITBlockPass: Fix a possible dereference of an invalid iterator. This was
    introduced in r106343, but only showed up recently (with a particular compiler &
    linker combination) because of the particular check, and because we have no
    builtin checking for dereferencing the end of an array, which is truly
    unfortunate.

    Don't track kills in VNInfo. Use interval ends instead.

    The VNInfo.kills vector was almost unused except for all the code keeping it
    updated. The few places using it were easily rewritten to check for interval
    ends instead.

    The two new methods LiveInterval::killedAt and killedInRange are replacements.

    This brings us down to 3 independent data structures tracking kills.

    SCEVUnknown values which are loop-variant, as LSR can't do anything

    for an "i" constraint should get lowered; PR 6309.  While

    IT instructions are considered to be scheduling hazards, but are scheduled
    with the following instructions. This is done via trickery by considering the
    instruction preceding the IT to be the hazard. Care must be taken to ensure
    it's the first non-debug instruction, or the presence of debug info will
    affect codegen.

    Part of the continuing work for rdar://7797940, making ARM code-gen unaffected

    but since -relocation-model=static doesn't work on Darwin
    x86-64, it was not testing what it was supposed to be testing

    Replace a big gob of old coalescer logic with the new CoalescerPair class.

    CoalescerPair can determine if a copy can be coalesced, and which register gets

    something a bit too convoluted.

    This second attempt fixes some crashes that only occurred Linux.

    Verify that VNI kills are pointing to existing instructions.

    In this case it is essential that the kill is real because the spiller will
    decide to omit a spill if it thinks there is a later kill.

Author: Dan Gohman <gohman@apple.com>
Date:   Thu Jun 24 15:04:11 2010 +0000

    Eliminate the first have of the optimization which eliminates BRCOND
    when the condition is constant. This optimization shouldn't be
    necessary, because codegen shouldn't be able to find dead control
    paths that the IR-level optimizer can't find. And it's undesirable,
    because it encourages bugpoint to leave "br i1 false" branches
    in its output. And it wasn't updating the CFG.

    I updated all the tests I could, but some tests are too reduced
    and I wasn't able to meaningfully preserve them.

    Replace a big gob of old coalescer logic with the new CoalescerPair class.

    CoalescerPair can determine if a copy can be coalesced, and which register gets
    merged away. The old logic in SimpleRegisterCoalescing had evolved into
    something a bit too convoluted.

    We are missing opportunites to use ldm. Take code like this:

    void t(int *cp0, int *cp1, int *dp, int fmd) {
      int c0, c1, d0, d1, d2, d3;
      c0 = (*cp0++ & 0xffff) | ((*cp1++ << 16) & 0xffff0000);
      c1 = (*cp0++ & 0xffff) | ((*cp1++ << 16) & 0xffff0000);
      /* ... */
    }

    It code gens into something pretty bad. But with this change (analogous to the
    X86 back-end), it will use ldm and generate few instructions.

    Add an extra-library-path option to the plugin. This is used to support
    having a library both as bitcode and native code. We want to use the
    bitcode first, but if codegen produces new undefined references we have to use
    the native code to satisfy those references.

    Gold has no notion of bitcode and native search directories, so instead it has

    Fix a tblgen bug.

    Given the pattern below as an example:
    list<dag> Pattern = [(set RC:$dst, (v4f32 (shufp:src3 RC:$src1,
                                (mem_frag addr:$src2))))];

    The right reference resolving should lead to:
    list<dag> Pattern = [(set VR128:$dst, (v4f32 (shufp:src3 VR128:$src1,
                                (mem_frag addr:$src2))))];
    But was yielding:
    list<dag> Pattern = [(set VR128:$dst, (v4f32 (shufp VR128:$src1,
                                (mem_frag addr:$src2))))];

    Fix this by passing the right name when creating a new DagInit node.

    Some targets don't require the fencing MEMBARRIER instructions surrounding

    atomics, or because they perform the locking directly. Add support in the
    DAG combiner to fold away the fences.

    If a metadata operand is seeded in value map and the metadata should also be seeded in value map. This is not limited to function local metadata.

    Failure to seed metdata in such cases causes troubles when in a cloned module, metadata from a new module refers to values in old module. Usually this results in mysterious bugpoint crashes. For example,

    This does not affect codegen much because SUBREG_TO_REG is only used by X86 and

commit 866711e285cf5a9c8078c15615ee338d99c92d66
Author: Dan Gohman <gohman@apple.com>
Date:   Mon Jun 21 22:17:20 2010 +0000

    Teach two-address lowering how to unfold a load to open up commuting
    opportunities. For example, this lets it emit this:

       movq (%rax), %rcx
       addq %rdx, %rcx

    instead of this:

       movq %rdx, %rcx
       addq (%rax), %rcx

    in the case where %rdx has subsequent uses. It's the same number
    of instructions, and usually the same encoding size on x86, but
    it appears faster, and in general, it may allow better scheduling
    for the load.

    Split the code for materializing a value out of

    uses it, for use in code which doesn't want a CopyFromReg even
    when FuncMap.ValueMap already has an entry for it.

    Include the use kind along with the expression in the key of the
    use sharing map. The reconcileNewOffset logic already forces a
    separate use if the kinds differ, so incorporating the kind in the
    key means we can track more sharing opportunities.

    More sharing means fewer total uses to track, which means smaller
    problem sizes, which means the conservative throttles don't kick
    in as often.

    Allow ARM if-converter to be run after post allocation scheduling.
    - This fixed a number of bugs in if-converter, tail merging, and post-allocation
      scheduler. If-converter now runs branch folding / tail merging first to
      maximize if-conversion opportunities.
    - Also changed the t2IT instruction slightly. It now defines the ITSTATE
      register which is read by instructions in the IT block.
    - Added Thumb2 specific hazard recognizer to ensure the scheduler doesn't
      change the instruction ordering in the IT block (since IT mask has been
      finalized). It also ensures no other instructions can be scheduled between
      instructions in the IT block.

    This is not yet enabled.

    Enable tail calls on ARM by default, with some
    basic tests.

    This has been well tested on Darwin but not elsewhere.
    It should work provided the linker correctly resolves
      B.W  <label in other function>
    which it has not seen before, at least from llvm-based
    compilers.  I'm leaving the arm-tail-calls switch in
    until I see if there's any problems because of that;
    it might need to be disabled for some environments.

commit e7fe0d559ecf031a8b426d23ec1f967931d63b3a
Author: Bob Wilson <bob.wilson@apple.com>
Date:   Fri Jun 18 17:07:23 2010 +0000

    Fix PR7372: Conditional branches (at least on ARM) are treated as predicated,
    so when IfConverter::CopyAndPredicateBlock checks to see if it should ignore
    an instruction because it is a branch, it should not check if the branch is
    predicated.

    This case (when IgnoreBr is true) is only relevant from IfConvertTriangle,
    where new branches are inserted after the block has been copied and predicated.
    If the original branch is not removed, we end up with multiple conditional
    branches (possibly conflicting) at the end of the block.  Aside from any
    immediate errors resulting from that, this confuses the AnalyzeBranch functions
    so that the branches are not analyzable.  That in turn causes the IfConverter to
    think that the "Simple" pattern can be applied, and things go downhill fast
    because the "Simple" pattern does _not_ apply if the block can fall through.

    This is pretty fragile.  If there are other degenerate cases where AnalyzeBranch
    fails, but where the block may still fall through, the IfConverter should not
    perform its "Simple" if-conversion.  But, I don't know how to do that with the
    current AnalyzeBranch interface, so for now, the best thing seems to be to
    avoid creating branches that AnalyzeBranch cannot handle.

    Evan, please review!

    Add entries for Expanding atomic intrinsics to libcalls. Just a placeholder
    for the moment. The implementation of the libcall will follow.

    Currently, the llvm-gcc knows when the intrinsics can be correctly handled by
    the back end and only generates them in those cases, issuing libcalls directly
    otherwise. That's too much coupling. The intrinsics should always be
    generated and the back end decide how to handle them, be it with a libcall,
    inline code, or whatever. This patch is a step in that direction.

    Allow a register to be redefined multiple times in a basic block.

    LiveVariableAnalysis was a bit picky about a register only being redefined once,
    but that really isn't necessary.

    Here is an example of chained INSERT_SUBREGs that we can handle now:

    68      %reg1040<def> = INSERT_SUBREG %reg1040, %reg1028<kill>, 14
                    register: %reg1040 +[70,134:0)
    76      %reg1040<def> = INSERT_SUBREG %reg1040, %reg1029<kill>, 13
                    register: %reg1040 replace range with [70,78:1) RESULT: %reg1040,0.000000e+00 = [70,78:1)[78,134:0)  0@78-(134) 1@70-(78)
    84      %reg1040<def> = INSERT_SUBREG %reg1040, %reg1030<kill>, 12
                    register: %reg1040 replace range with [78,86:2) RESULT: %reg1040,0.000000e+00 = [70,78:1)[78,86:2)[86,134:0)  0@86-(134) 1@70-(78) 2@78-(86)
    92      %reg1040<def> = INSERT_SUBREG %reg1040, %reg1031<kill>, 11
                    register: %reg1040 replace range with [86,94:3) RESULT: %reg1040,0.000000e+00 = [70,78:1)[78,86:2)[86,94:3)[94,134:0)  0@94-(134) 1@70-(78) 2@78-(86) 3@86-(94)

    Create a more targeted fix for not sinking instructions into a range where it
    will conflict with another live range. The place which creates this scenerio is
    the code in X86 that lowers a select instruction by splitting the MBBs. This
    eliminates the need to check from the bottom up in an MBB for live pregs.

    Fix an exotic bug that only showed up in an internal test case.

    SimpleRegisterCoalescing::JoinIntervals() uses CoalescerPair to determine if a
    copy is coalescable, and in very rare cases it can return true where LHS is not
    live - the coalescable copy can come from an alias of the physreg in LHS.

    case in a symmetrical way to the case when the destination is smaller.

    Avoid processing early clobbers twice in RegAllocFast.

    Early clobbers defining a virtual register were first alocated to a physreg and

    Add CoalescerPair helper class.

    Given a copy instruction, CoalescerPair can determine which registers to
    coalesce in order to eliminate the copy. It deals with all the subreg fun to
    determine a tuple (DstReg, SrcReg, SubIdx) such that:

    - SrcReg is a virtual register that will disappear after coalescing.
    - DstReg is a virtual or physical register whose live range will be extended.
    - SubIdx is 0 when DstReg is a physical register.
    - SrcReg can be joined with DstReg:SubIdx.

    CoalescerPair::isCoalescable() determines if another copy instruction is
    compatible with the same tuple. This fixes some NEON miscompilations where
    shuffles are getting coalesced as if they were copies.

    The CoalescerPair class will replace a lot of the spaghetti logic in JoinCopy
    later.

    Generalize the pre-coalescing of extract_subregs feeding reg_sequences,
    replacing the overly conservative checks that I had introduced recently to
    deal with correctness issues.  This makes a pretty noticable difference

    check that we no longer emit the unnecessary subreg moves.

    symbols as declarations in the X86 backend.  This would manifest
    on darwin x86-32 as errors like this with -fvisibility=hidden:

    Add instruction encoding for the Neon VMOV immediate instruction.  This changes
    the machine instruction representation of the immediate value to be encoded
    into an integer with similar fields as the actual VMOV instruction.  This makes
    things easier for the disassembler, since it can just stuff the bits into the
    immediate operand, but harder for the asm printer since it has to decode the
    value to be printed.  Testcase for the encoding will follow later when MC has
    more support for ARM.

    Define ContextualFoldingSet, which stores a context parameter to pass down to
    the Profile method.  Currently this only works with the default FoldingSetTraits
    implementation.

    The point of this is to allow nodes to not store context values which are only
    used during profiling.  A better solution would thread this value through the
    folding algorithms, but then those would need to be (1) templated and
    (2) non-opaque.

    Avoid many "variable 'Sub' set but not used [-Wunused-but-set-variable]" warnings

    and massively reduces the amount of warning spew, just workaround the wrong warning.

    It's an error to translate this:

       %reg1025 = <sext> %reg1024
        ...
       %reg1026 = SUBREG_TO_REG 0, %reg1024, 4

    into this:

       %reg1025 = <sext> %reg1024
        ...
       %reg1027 = EXTRACT_SUBREG %reg1025, 4
       %reg1026 = SUBREG_TO_REG 0, %reg1027, 4

    The problem here is that SUBREG_TO_REG is there to assert that an implicit zext
    occurs. It doesn't insert a zext instruction. If we allow the EXTRACT_SUBREG
    here, it will give us the value after the <sext>, not the original value of
    %reg1024 before <sext>.

    Thumb2 IT blocks are fairly expensive. When there are multiple selects using
    the same condition, it's important to make sure they are scheduled together
    to avoid forming multiple IT blocks. I'm adding a pre-regalloc pass that forms
    IT blocks early (by re-scheduling instructions and split basic blocks) to
    attempt to fix this. This is not turned on by default since I am not sure this
    is the right fix.

    Another issue is llvm selects are modeled as two-address conditional moves.
    This can be very bad when the copies before the conditional moves are not
    coalesced away. Teach IT formation pass to move the copies above the IT block
    (when legal) to avoid breaking the IT block.

    Incremental improvement to the handling of the x86 "Jump if rCX Zero"
    instruction.  Added the 64-bit version "jrcxz" so it is recognized and also
    added the checks for incorrect uses of "jcxz" in 64-bit mode and "jrcxz" in
    32-bit mode.  Still to do is to correctly handle the encoding of the
    instruction adding the Address-size override prefix byte, 0x67, when the width
    of the count register is not the same as the mode the machine is running in.
    Which for example means the encoding of "jecxz" depends if you are assembling
    as a 32-bit target or a 64-bit target.

    Further changes for Neon vector shuffles:
    - change isShuffleMaskLegal to show that all shuffles with 32-bit and 64-bit
      elements are legal
    - the Neon shuffle instructions do not support 64-bit elements, but we were
      not checking for that before lowering shuffles to use them
    - remove some 64-bit element vduplane patterns that are no longer needed

    LSR needs to remember inserted instructions even in postinc mode, because
    there could be multiple subexpressions within a single expansion which
    require insert point adjustment. This fixes PR7306.

    Fixed a bug during widening where we would avoid legalizing a node.  When we
    replace an OpA with a widened OpB, it is possible to get new uses of OpA due to CSE
    when recursively updating nodes.  Since OpA has been processed, the new uses are
    not examined again.  The patch checks if this occurred and it it did, updates the
    new uses of OpA to use OpB.

    For NEON vectors with 32- or 64-bit elements, select BUILD_VECTORs and
    VECTOR_SHUFFLEs to REG_SEQUENCE instructions.  The standard ISD::BUILD_VECTOR
    node corresponds closely to REG_SEQUENCE but I couldn't use it here because
    its operands do not get legalized.  That is pretty awful, but I guess it
    makes sense for other targets.  Instead, I have added an ARM-specific version
    of BUILD_VECTOR that will have its operands properly legalized.
    This fixes the rest of Radar 7872877.

    Add some missing checks in TwoAddressInstructionPass::CoalesceExtSubRegs.
    Check that all the instructions are in the same basic block, that the
    EXTRACT_SUBREGs write to the same subregs that are being extracted, and that
    the source and destination registers are in the same regclass.  Some of
    these constraints can be relaxed with a bit more work.  Jakob suggested
    that the loop that checks for subregs when NewSubIdx != 0 should use the
    "nodbg" iterator, so I made that change here, too.

    Machine sink could potentially sink instructions into a block where the physical
    registers it defines then interfere with an existing preg live range.

    For instance, if we had something like these machine instructions:

    BB#0
      ... = imul ... EFLAGS<imp-def,dead>
      test ..., EFLAGS<imp-def>
      jcc BB#2 EFLAGS<imp-use>

    BB#1
      ... ; fallthrough to BB#2

    BB#2
      ... ; No code that defines EFLAGS
      jcc ... EFLAGS<imp-use>

    Machine sink will come along, see that imul implicitly defines EFLAGS, but
    because it's "dead", it assumes that it can move imul into BB#2. But when it
    does, imul's "dead" imp-def of EFLAGS is raised from the dead (a zombie) and
    messes up the condition code for the jump (and pretty much anything else which
    relies upon it being correct).

    The solution is to know which pregs are live going into a basic block. However,
    that information isn't calculated at this point. Nor does the LiveVariables pass
    take into account non-allocatable physical registers. In lieu of this, we do a
    *very* conservative pass through the basic block to determine if a preg is live
    coming out of it.

    Implement expansion in type legalization for add/sub with overflow.  The
    expansion is the same as that used by LegalizeDAG.

    The resulting code sucks in terms of performance/codesize on x86-32 for a
    64-bit operation; I haven't looked into whether different expansions might be
    better in general.

    Use readsWritesVirtualRegister instead of counting uses and defs when inserting
    spills and reloads.

    This means that a partial define of a register causes a reload so the other
    parts of the register are preserved.

    The reload can be prevented by adding an <imp-def> operand for the full
    register. This is already done by the coalescer and live interval analysis where
    relevant.

    Add full register <imp-def> operands when the coalescer is creating partial

    These operands tell the spiller that the other parts of the partially defined
    register are don't-care, and a reload is not necessary.

    Slightly change the meaning of the reMaterialize target hook when the original
    instruction defines subregisters.

    Any existing subreg indices on the original instruction are preserved or
    composed with the new subreg index.

    Also substitute multiple operands mentioning the original register by using the
    new MachineInstr::substituteRegister() function. This is necessary because there
    will soon be <imp-def> operands added to non read-modify-write partial
    definitions. This instruction:

      %reg1234:foo = FLAP %reg1234<imp-def>

    will reMaterialize(%reg3333, bar) like this:

      %reg3333:bar-foo = FLAP %reg333:bar<imp-def>

    Finally, replace the TargetRegisterInfo pointer argument with a reference to
    indicate that it cannot be NULL.

    Don't try to custom-lower 64-bit add-with-overflow and friends on x86-32; the
    x86 backend currently doesn't know how to handle them.

    This doesn't really fix anything because LegalizeTypes doesn't know how to
    handle them either.  We do get a better error message, though.

    Merge the SystemZ subreg_even32 SubRegIndex into subreg_32bit. The SubRegIndices
    were overspecified when inheriting sub-subregisters, for instance:

    R0Q:subreg_even32 = R0Q:subreg_32bit = R0Q:subreg_even:subreg_32bit.

    This meant that composeSubRegIndices(subreg_even, subreg_32bit) was ambiguous.

    Add support to tablegen for auto-generating arm_neon.h from a tablegen description
    of the intrinsics.  The goal is to auto-generate both support for GCC-style (vector)

    This is work in progress, but will be completed soon.

    When handling raw_ostream errors manually, use clear_error() so that
    raw_ostream doesn't try to do its own error handling.

    Replace the SubRegSet tablegen class with a less error-prone mechanism.

    A Register with subregisters must also provide SubRegIndices for adressing the
    subregisters. TableGen automatically inherits indices for sub-subregisters to
    minimize typing.

    CompositeIndices may be specified for the weirder cases such as the XMM sub_sd
    index that returns the same register, and ARM NEON Q registers where both D
    subregs have ssub_0 and ssub_1 sub-subregs.

    It is now required that all subregisters are named by an index, and a future
    patch will also require inherited subregisters to be named. This is necessary to

    Replace the SubRegSet tablegen class with a less error-prone mechanism.

    A Register with subregisters must also provide SubRegIndices for adressing the
    subregisters. TableGen automatically inherits indices for sub-subregisters to
    minimize typing.

    CompositeIndices may be specified for the weirder cases such as the XMM sub_sd
    index that returns the same register, and ARM NEON Q registers where both D
    subregs have ssub_0 and ssub_1 sub-subregs.

    It is now required that all subregisters are named by an index, and a future
    patch will also require inherited subregisters to be named. This is necessary to
    allow composite subregister indices to be reduced to a single index.

    Okay, bear with me here...

    If you have a setjmp/longjmp situation, it's possible for stack slot coloring to
    reuse a stack slot before it's really dead. For instance, if we have something
    like this:

    1:  y = g;
        x = sigsetjmp(env, 0);
        switch (x) {
        case 1:
          /* ... */
          goto run;
        case 0:
      run:
          do_run(); /* marked as "no return" */
          break;
        case 3:
          if (...) {
            /* ... */
            goto run;
          }
          /* ... */
          break;
        }

    2:  g = y;

    "y" may be put onto the stack, so the expression "g = y" is relying upon the
    fact that the stack slot containing "y" isn't modified between (1) and (2). But
    it can be, because of the "no return" calls in there. A longjmp might come back
    with 3, modify the stack slot, and then go to case 0. And it's perfectly
    acceptable to reuse the stack slot there because there's no CFG flow from case 3
    to (2).

    The fix is to disable certain optimizations in these situations. Ideally, we'd
    disable them for all "returns twice" functions. But we don't support that
    attribute. Check for "setjmp" and "sigsetjmp" instead.

Date:   Tue May 25 20:52:34 2010 +0000

    Changed the encoding of X86 floating point stack operations where both operands
    are st(0).  These can be encoded using an opcode for storing in st(0) or using
    an opcode for storing in st(i), where i can also be 0.  To allow testing with
    the darwin assembler and get a matching binary the opcode for storing in st(0)
    is now used.  To do this the same logical trick is use from the darwin assembler
    in converting things like this:

    fmul %st(0), %st

    into this:

    fmul %st(0)

    by looking for the second operand being X86::ST0 for specific floating point
    mnemonics then removing the second X86::ST0 operand.  This also has the add
    benefit to allow things like:

    fmul %st(1), %st

    that llvm-mc did not assemble.

    Ignore NumberHack and give each SubRegIndex instance a unique enum value instead.

    This passes lit tests, but I'll give it a go through the buildbots to smoke out
    any remaining places that depend on the old SubRegIndex numbering.

    Then I'll remove NumberHack entirely.

    Replace the tablegen RegisterClass field SubRegClassList with an alist-like data
    structure that represents a mapping without any dependencies on SubRegIndex
    numbering.

    This brings us closer to being able to remove the explicit SubRegIndex
    numbering, and it is now possible to specify any mapping without inventing
    *_INVALID register classes.

    - Change MachineInstr::findRegisterDefOperandIdx so it can also look for defs
    that are aliases of the specified register.
    - Rename modifiesRegister to definesRegister since it's looking a def of the
    specific register or one of its super-registers. It's not looking for def of a
    sub-register or alias that could change the specified register.
    - Added modifiesRegister to look for defs of aliases.

    added an assertion to MCObjectWriter::WriteBytes to catch misuse of the ZeroFillSize parameter

    If the size of the string is greater than the zero fill size, the function will attempt to write a very large string of zeros to the object file (~4GB on 32 bit platforms). This assertion will catch the scenario and crash the program before the write occurs.

    now that fp reg kill insertion stuff happens as a separate
    pass after isel instead of being interlaced with it, we can
    trust that all the code for a function has been isel'd before
    it is run.

    The practical impact of this is that we can scan for machine
    instr phis instead of doing a fuzzy match on the LLVM BB for
    phi nodes.  Doing the fuzzy match required knowing when isel
    would produce an fp reg stack phi which was gross.  It was
    also wrong in cases where select got lowered to a branch
    tree because cmovs aren't available (PR6828).

    Just do the scan on machine phis which is simpler, faster
    and more correct.  This fixes PR6828.

    Teach VirtRegRewriter to handle spilling in instructions that have multiple
    definitions of the virtual register.

    This happens when spilling the registers produced by REG_SEQUENCE:

    %reg1047:5<def>, %reg1047:6<def>, %reg1047:7<def> = VLD3d8 %reg1033, 0, pred:14, pred:%reg0

    The rewriter would spill the register multiple times, dead store elimination
    tried to keep up, but ended up cutting the branch it was sitting on.

    If the first definition of a virtual register is a partial redef, add an

    When canonicalizing icmp operand order to put the loop invariant
    operand on the left, the interesting operand is on the right. This
    fixes a bug where LSR was failing to recognize ICmpZero uses,
    which led it to be unable to reverse the induction variable in the
    attached testcase.

    Delete test/CodeGen/X86/stack-color-with-reg-2.ll, because its test
    is extremely fragile and hard to meaningfully update.

    The PPC MFCR instruction implicitly uses all 8 of the CR
    registers.  Currently it is not so marked, which leads to
    VCMPEQ instructions that feed into it getting deleted.
    If it is so marked, local RA complains about this sequence:
     vreg = MCRF  CR0
     MFCR  <kill of whatever preg got assigned to vreg>
    All current uses of this instruction are only interested in
    one of the 8 CR registers, so redefine MFCR to be a normal
    unary instruction with a CR input (which is emitted only as
    a comment).  That avoids all problems.  7739628.

    Add a hybrid bottom up scheduler that reduce register usage while avoiding
    pipeline stall. It's useful for targets like ARM cortex-a8. NEON has a lot
    of long latency instructions so a strict register pressure reduction
    scheduler does not work well.
    Early experiments show this speeds up some NEON loops by over 30%.

    Add MachineInstr::readsVirtualRegister() in preparation for proper handling of
    partial redefines.

    We are going to treat a partial redefine of a virtual register as a
    read-modify-write:

      %reg1024:6 = OP

    Unless the register is fully clobbered:

      %reg1024:6 = OP, %reg1024<imp-def>

    MachineInstr::readsVirtualRegister() knows the difference. The first case is a
    read, the second isn't.

    When expanding a vector_shuffle, the element type may not be legal and may

    Intrinsics which do a vector compare (results are all zero or all ones) are modeled as icmp / fcmp + sext. This is turned into a vsetcc by dag combine (yes, not a good long term solution). The targets can then isel the vsetcc to the appropriate instruction.

    The trouble arises when the result of a vector cmp + sext is then and'ed with all ones. Instcombine will turn it into a vector cmp + zext, dag combiner will miss turning it into a vsetcc and hell breaks loose after that.

    Teach dag combine to turn a vector cpm + zest into a vsetcc + and 1. This fixes rdar://7923010.

    make mcinstlower remove all but the first operand to CALL64pcrel32.
    The register use operands (e.g. the first argument is passed in a
    register) is currently being modeled as a normal register use,
    instead of correctly being an implicit use.  This causes the operand
    to get propagated onto the mcinst, which was causing the encoder to
    emit a rex prefix byte, which generates an invalid call.

    ARMBaseRegisterInfo::estimateRSStackSizeLimit() could return prematurely with a
    too large limit.

    The function would return immediately when finding an addrmode 3/5 instruction.
    It needs to keep scanning in case there is an addrmode 6 instruction which drops
    the limit to 0.

    A test case is very difficult to produce because it will only fail when the
    scavenger is used.

    MC/Mach-O: Fix some differences in symbol flag handling.
     - Don't clear weak reference flag, 'as' was only "trying" to do this, it wasn't
       actually succeeding.
     - Clear the "lazy bound" bit when we mark something external. This corresponds
       roughly to the lazy clearing of the bit that 'as' implements in
       symbol_table_lookup.
     - The exact meaning of these flags appears pretty loose, since 'as' isn't very
       consistent. For now we just try to match 'as', we will clean this up one day
       hopefully.

    llvm-mc: Support reassignment of variables in one special case, when the

    Avoid allocating the same physreg to multiple virtregs in one instruction.

    While that approach works wonders for register pressure, it tends to break
    everything.

    This should unbreak the arm-linux builder and fix a number of miscompilations.

    Extract spill cost calculation to a new method, and use definePhysReg() to clear
    out aliases when allocating. Clean up allocVirtReg().

    Use calcSpillCost() to allow more aggressive hinting. Now the hint is always
    taken unless blocked by a reserved register. This leads to more coalescing,
    lower register pressure, and less spilling.

    Fix uint64->{float, double} conversion to do rounding correctly in 32-bit.

    The implementation in LegalizeIntegerTypes to handle this as
    sint64->float + appropriate power of 2 is subject to double rounding,
    considered incorrect by numerics people.  Use this implementation only
    when it is safe.  This leads to using library calls in some cases
    that produced inline code before, but it's correct now.
    (EVTToAPFloatSemantics belongs somewhere else, any suggestions?)

    Add a correctly rounding (though not particularly fast) conversion
    that uses X87 80-bit computations for x86-32.

Author: Jakob Stoklund Olesen <stoklund@2pi.dk>
Date:   Sat May 15 06:09:08 2010 +0000

    Calculate liveness on the fly for local registers.

    When working top-down in a basic block, substituting physregs for virtregs, the use-def chains are kept up to date. That means we can recognize a virtreg kill by the use-def chain becoming empty.

    This makes the fast allocator independent of incoming kill flags.

commit 92b52c62a57eff0277f64f2f593825ee8a4dc05c
Author: Evan Cheng <evan.cheng@apple.com>
Date:   Fri May 14 23:21:14 2010 +0000

    Teach two-address pass to do some coalescing while eliminating REG_SEQUENCE
    instructions.

    e.g.
    %reg1026<def> = VLDMQ %reg1025<kill>, 260, pred:14, pred:%reg0
    %reg1027<def> = EXTRACT_SUBREG %reg1026, 6
    %reg1028<def> = EXTRACT_SUBREG %reg1026<kill>, 5
    ...
    %reg1029<def> = REG_SEQUENCE %reg1028<kill>, 5, %reg1027<kill>, 6, %reg1028, 7, %reg1027, 8, %reg1028, 9, %reg1027, 10, %reg1030<kill>, 11, %reg1032<kill>, 12

    After REG_SEQUENCE is eliminated, we are left with:

    %reg1026<def> = VLDMQ %reg1025<kill>, 260, pred:14, pred:%reg0
    %reg1029:6<def> = EXTRACT_SUBREG %reg1026, 6
    %reg1029:5<def> = EXTRACT_SUBREG %reg1026<kill>, 5

    The regular coalescer will not be able to coalesce reg1026 and reg1029 because it doesn't
    know how to combine sub-register indices 5 and 6. Now 2-address pass will consult the
    target whether sub-registers 5 and 6 of reg1026 can be combined to into a larger
    sub-register (or combined to be reg1026 itself as is the case here). If it is possible,
    it will be able to replace references of reg1026 with reg1029 + the larger sub-register
    index.

    SystemZ really does mean "has calls" and not just "adjusts stack." Go ahead and

    Fix an embarrassing runtime regression for RegAllocFast.

    This loop is quadratic in the capacity for a DenseMap:

      while(!map.empty())
        map.erase(map.begin());

    Instead we now do a normal begin() - end() iteration followed by map.clear().
    That also has the nice sideeffect of shrinking the map capacity on demand.

    Replace the core comparison login in merge functions. We can now merge
    vector<>::push_back() in:

      int foo(vector<int> &a, vector<unsigned> &b) {
        a.push_back(10);
        b.push_back(11);
      }

    to two calls to the same push_back function, or fold away the two copies of
    push_back() in:

      struct T { int; };
      struct S { char; };
      vector<T*> t;
      vector<S*> s;
      void f(T *x) { t.push_back(x); }
      void g(S *x) { s.push_back(x); }

    but leave f() and g() separate, since they refer to two different global
    variables.

    updated support for the COFF .linkonce

    Now, the .linkonce directive is emitted as part of MCSectionCOFF::PrintSwitchToSection instead of AsmPrinter::EmitLinkage since it is an attribute of the section the symbol was placed into not the symbol itself.

commit de7c1ddcc6e8ad3dee6a6585535bbc312ff456e8
Author: Evan Cheng <evan.cheng@apple.com>
Date:   Wed May 12 01:42:50 2010 +0000

    vst instructions are modeled as this:
    v1024 = REG_SEQUENCE ...
    v1025 = EXTRACT_SUBREG v1024, 5
    v1026 = EXTRACR_SUBREG v1024, 6
          = VSTxx <addr>, v1025, v1026

    The REG_SEQUENCE ensures the sources that feed into the VST instruction
    are getting the right register allocation so they form a large super-
    register. The extract_subreg will be coalesced away all would just work:
    v1024 = REG_SEQUENCE ...
          = VSTxx <addr>, v1024:5, v1024:6

    The problem is if the coalescer isn't run, the extract_subreg instructions
    would stick around and there is no assurance v1025 and v1026 will get the
    right registers.

    As a short term workaround, teach the NEON pre-allocation pass to transfer
    the sub-register indices over. An alternative would be do it 2addr pass
    when reg_sequence's are eliminated. But that *seems* wrong and require
    updating liveness information.

    Another alternative is to do this in the scheduler when the instructions are
    created. But that would mean somehow the scheduler this has to be done for
    correctness reason. That's yucky as well. So for now, we are leaving this
    in the target specific pass.

    Mostly rewrite RegAllocFast.

    Sorry for the big change. The path leading up to this patch had some TableGen
    changes that I didn't want to commit before I knew they were useful. They
    weren't, and this version does not need them.

    The fast register allocator now does no liveness calculations. Instead it relies
    on kill flags provided by isel. (Currently those kill flags are also ignored due
    to isel bugs). The allocation algorithm is supposed to work with any subset of
    valid kill flags. More kill flags simply means fewer spills inserted.

    Registers are allocated from a working set that contains no aliases. That means
    most allocations can be done directly without expensive alias checks. When the
    working set runs out of registers we do the full alias check to find new free
    registers.

    The getDefaultSubtargetFeatures method of SubtargetFeature did actually return a
    string of features for that target. However LTO was using that string to pass
    into the "create target machine" stuff. That stuff needed the feature string to
    be in a particular form. In particular, it needed the CPU specified first and
    then the attributes. If there isn't a CPU specified, it required it to be blank
    -- e.g., ",+altivec". Yuck.

    Modify the getDefaultSubtargetFeatures method to be a non-static member
    function. For all attributes for a specific subtarget, it will add them in like
    normal. It will also take a CPU string so that it can satisfy this horrible
    syntax.

    Fix PR6875:

    This includes a patch by Roman Divacky to fix the initial crash.

    Move the actual addition of passes from *PassManager::add to
    *PassManager::addImpl.  That way, when adding printer passes we won't
    recurse infinitely.

    Finally, check to make sure that we are actually adding a FunctionPass
    to a FunctionPassManager before doing a print before or after it.
    Immutable passes are strange in this way because they aren't
    FunctionPasses yet they can be and are added to the FunctionPassManager.

    make simplifycfg insert an llvm.trap before the 'unreachable' it introduces
    when it detects undefined behavior.  llvm.trap generally codegens into some
    thing really small (e.g. a 2 byte ud2 instruction on x86) and debugging this
    sort of thing is "nontrivial".  For example, we now compile:

    void foo() { *(int*)0 = 42; }

    into:

    _foo:
    	pushl	%ebp
    	movl	%esp, %ebp
    	ud2

    Some may even claim that this is a security hole, though that seems dubious
    to me.  This addresses rdar://7958343 - Optimizing away null dereference

    Teach instcombine to transform a bitcast/(zext|trunc)/bitcast sequence
    with a vector input and output into a shuffle vector.  This sort of
    sequence happens when the input code stores with one type and reloads
    with another type and then SROA promotes to i96 integers, which make
    everyone sad.

commit 9c11c476d0857bcd7fd687a6ec5bf0d957740d67
Author: Dan Gohman <gohman@apple.com>
Date:   Fri May 7 23:36:59 2010 +0000

    When pruning candidate formulae out of an LSRUse, update the
    LSRUse's Regs set after all pruning is done, rather than trying
    to do it on the fly, which can produce an incomplete result.

    This fixes a case where heuristic pruning was stripping all
    formulae from a use, which led the solver to enter an infinite
    loop.

    Also, add a few asserts to diagnose this kind of situation.

    Overhauled llvm/clang docs builds. Closes PR6613.

    NOTE: 2nd part changeset for cfe trunk to follow.

    *** PRE-PATCH ISSUES ADDRESSED

    - clang api docs fail build from objdir
    - clang/llvm api docs collide in install PREFIX/
    - clang/llvm main docs collide in install
    - clang/llvm main docs have full of hard coded destination
      assumptions and make use of absolute root in static html files;
      namely CommandGuide tools hard codes a website destination
      for cross references and some html cross references assume
      website root paths

    *** IMPROVEMENTS

    - bumped Doxygen from 1.4.x -> 1.6.3
    - splits llvm/clang docs into 'main' and 'api' (doxygen) build trees
    - provide consistent, reliable doc builds for both main+api docs
    - support buid vs. install vs. website intentions
    - support objdir builds
    - document targets with 'make help'
    - correct clean and uninstall operations
    - use recursive dir delete only where absolutely necessary
    - added call function fn.RMRF which safeguards against botched 'rm -rf';
      if any target (or any variable is evaluated) which attempts
      to remove any dirs which match a hard-coded 'safelist', a verbose
      error will be printed and make will error-stop.

    Fix handling of unreachable blocks in the SSAUpdater.  The previous code only
    handled cases where a block had zero predecessors, but failed to detect other
    cases like loops with no entries.  The SSAUpdater is already doing a forward
    traversal through the blocks, so it is not hard to identify the blocks that
    were never reached on that traversal.  This fixes the crash for ppc on the
    stepanov_vector test.

    Fixes a coalescer bug that caused llc to crash on 2009-11-30-LiveVariablesBug.ll
    with the fix in 103157.

    %reg1039:1<def> = VMOVS %S1<kill>, pred:14, pred:%reg0
    is not coalescable since none of the super-registers of S1 are in reg1039's
    register class: DPR_VFP2. But it is still a legal copy instruction so it should
    not assert.

    Implement rdar://7415680 - Twine integer support lacks greatness

    Microoptimize Twine's with unsigned and int to not pin their value to
    the stack.  This saves stack space in common cases and allows mem2reg
    in the caller.  A simple example is:

    void foo(const Twine &);
    void bar(int x) {
      foo("xyz: " + Twine(x));
    }

    Before:

    __Z3bari:
    	subq	$40, %rsp
    	movl	%edi, 36(%rsp)
    	leaq	L_.str3(%rip), %rax
    	leaq	36(%rsp), %rcx
    	leaq	8(%rsp), %rdi
    	movq	%rax, 8(%rsp)
    	movq	%rcx, 16(%rsp)
    	movb	$3, 24(%rsp)
    	movb	$7, 25(%rsp)
    	callq	__Z3fooRKN4llvm5TwineE
    	addq	$40, %rsp
    	ret

    After:

    __Z3bari:
    	subq	$24, %rsp
    	leaq	L_.str3(%rip), %rax
    	movq	%rax, (%rsp)
    	movslq	%edi, %rax
    	movq	%rax, 8(%rsp)
    	movb	$3, 16(%rsp)
    	movb	$7, 17(%rsp)
    	leaq	(%rsp), %rdi
    	callq	__Z3fooRKN4llvm5TwineE
    	addq	$24, %rsp
    	ret

    It saves 16 bytes of stack and one instruction in this case.

    This is not exposed through anything in the compiler yet.

    Teach PHI elimination to remove REG_SEQUENCE instructions and update references of the source operands with references of the destination with subreg indices. e.g.
    %reg1029<def>, %reg1030<def> = VLD1q16 %reg1024<kill>, ...
    %reg1031<def> = REG_SEQUENCE %reg1029<kill>, 5, %reg1030<kill>, 6
    =>
    %reg1031:5<def>, %reg1031:6<def> = VLD1q16 %reg1024<kill>, ...

    PHI elimination now does more than phi elimination. It is really a de-SSA pass.

    MC/X86: Chris pointed that 'as' isn't consistent in accepting the long form of
    instructions which have no direct register usage.

    Darwin 'as' accepts:
      add $0, (%rax)
    but rejects
      mov $0, (%rax)
    for example.

    Given that, only accept suffix matches which match exactly one form. We still
    need to emit nice diagnostics for failures...

commit 56aac4fe4246be908ba4f892eae2ff5e2c578d1f
Author: Daniel Dunbar <daniel@zuster.org>
Date:   Tue May 4 16:12:42 2010 +0000

    MC/X86: Add "support" for matching ATT style mnemonic prefixes.
     - The idea is that when a match fails, we just try to match each of +'b', +'w',
       +'l'. If exactly one matches, we assume this is a mnemonic prefix and accept
       it. If all match, we assume it is width generic, and take the 'l' form.

     - This would be a horrible hack, if it weren't so simple. Therefore it is an
       elegant solution! Chris gets the credit for this particular elegant
       solution. :)

     - Next step to making this more robust is to have the X86 matcher generate the
       mnemonic prefix information. Ideally we would also compute up-front exactly
       which mnemonic to attempt to match, but this may require more custom code in
       the matcher than is really worth it.

    Fix a problem exposed by my previous commit and noticed by a release-asserts
    buildbot: the debugging and non-debugging versions of getFunction were not
    functionally equivalent: the non-debugging version wrongly assumed that if a
    metadata operand was not metadata, then it had a non-null containing function.
    This is not true, since the operand might be a global value, constant etc.

    Fix a variant of PR6112 found by thinking about it: when doing
    RAUW of a global variable with a local variable in function F,
    if function local metadata M in function G was using the global
    then M would become function-local to both F and G, which is not
    allowed.  See the testcase for an example.  Fixed by detecting
    this situation and zapping the metadata operand when it occurs.

    Fixed the encoding of the x86 push instructions.  Using a 32-bit immediate value
    caused the a pushl instruction to be incorrectly encoding using only two bytes
    of immediate, causing the following 2 instruction bytes to be part of the 32-bit
    immediate value.  Also fixed the one byte form of push to be used when the
    immediate would fit in a signed extended byte.  Lastly changed the names to not
    include the 32 of PUSH32 since they actually push the size of the stack pointer.

    rather than UINT64_MAX, even for integers wider than 64 bits.

    Fix a bug which prevented tail merging of return instructions in
    beneficial cases. See the changes in test/CodeGen/X86/tail-opts.ll and
    test/CodeGen/ARM/ifcvt2.ll for details.

    The fix is to change HashEndOfMBB to hash at most one instruction,
    instead of trying to apply heuristics about when it will be profitable to
    consider more than one instruction. The regular tail-merging heuristics
    are already prepared to handle the same cases, and they're more precise.

    Also, make test/CodeGen/ARM/ifcvt5.ll and
    test/CodeGen/Thumb2/thumb2-branch.ll slightly more complex so that they
    continue to test what they're intended to test.

    And, this eliminates the problem in
    test/CodeGen/Thumb2/2009-10-15-ITBlockBranch.ll, the testcase from
    PR5204. Update it accordingly.

    Implement rdar://6295824 and PR6724 with two tiny changes
    that can have a big effect :).  The first is to enable the
    iterative SCC passmanager juice that kicks in when the
    scc passmgr detects that a function pass has devirtualized
    a call.  In this case, it will rerun all the passes it
    manages on the SCC, up to the iteration count limit (4). This
    is useful because a function pass may devirualize a call, and
    we want the inliner to inline it, or pruneeh to infer stuff
    about it, etc.

    The second patch is to add *all* call sites to the
    DevirtualizedCalls list the inliner uses.  This list is
    about to get renamed, but the jist of this is that the
    inliner now reconsiders *all* inlined call sites as candidates
    for further inlining.  The intuition is this that in cases
    like this:

    f() { g(1); }     g(int x) { h(x); }

    We analyze this bottom up, and may decide that it isn't
    profitable to inline H into G.  Next step, we decide that it is
    profitable to inline G into F, and do so, which means that F
    now calls H.  Even though the call from G -> H may not have been
    profitable to inline, the call from F -> H may be (in this case
    because a constant allows folding etc).

    In my spot checks, this doesn't have a big impact on code.  For
    example, the LLC output for 252.eon grew from 0.02% (from
    317252 to 317308) and 176.gcc actually shrunk by .3% (from 1525612
    to 1520964 bytes).  252.eon never iterated in the SCC Passmgr,
    176.gcc iterated at most 1 time.

Author: Chris Lattner <sabre@nondot.org>
Date:   Sat May 1 01:05:10 2010 +0000

    The inliner has traditionally not considered call sites
    that appear due to inlining a callee as candidates for
    futher inlining, but a recent patch made it do this if
    those call sites were indirect and became direct.

    Unfortunately, in bizarre cases (see testcase) doing this
    can cause us to infinitely inline mutually recursive
    functions into callers not in the cycle.  Fix this by
    keeping track of the inline history from which callsite
    inline candidates got inlined from.

    This shouldn't affect any "real world" code, but is required
    for a follow on patch that is coming up next.

    Add a pseudo instruction REG_SEQUENCE that takes a list of registers and
    sub-register indices and outputs a single super register which is formed from
    a consecutive sequence of registers.

    This is used as register allocation / coalescing aid and it is useful to
    represent instructions that output register pairs / quads. For example,
    v1024, v1025 = vload <address>
    where v1024 and v1025 forms a register pair.

    This really should be modelled as
    v1024<3>, v1025<4> = vload <address>
    but it would violate SSA property before register allocation is done.

    Currently we use insert_subreg to form the super register:
    v1026 = implicit_def
    v1027 - insert_subreg v1026, v1024, 3
    v1028 = insert_subreg v1027, v1025, 4
    ...
          = use v1024
          = use v1028

    But this adds pseudo live interval overlap between v1024 and v1025.

    We can now modeled it as
    v1024, v1025 = vload <address>
    v1026 = REG_SEQUENCE v1024, 3, v1025, 4
    ...
          = use v1024
          = use v1026

    After coalescing, it will be
    v1026<3>, v1025<4> = vload <address>
    ...
          = use v1026<3>
          = use v1026

Date:   Sat May 1 00:25:44 2010 +0000

    Reorgnaize more switch code lowering to clean up some tricky
    code, and to eliminate the need for the SelectionDAGBuilder
    state to be live during CodeGenAndEmitDAG calls.

    Call SDB->clear() before CodeGenAndEmitDAG calls instead of
    before it, and move the CurDAG->clear() out of SelectionDAGBuilder,
    which doesn't own the DAG, and into CodeGenAndEmitDAG.

    Dan recently disabled recursive inlining within a function, but we
    were still inlining self-recursive functions into other functions.

    Inlining a recursive function into itself has the potential to
    reduce recursion depth by a factor of 2, inlining a recursive
    function into something else reduces recursion depth by exactly
    1.  Since inlining a recursive function into something else is a
    weird form of loop peeling, turn this off.

    The deleted testcase was added by Dale in r62107, since then
    we're leaning towards not inlining recursive stuff ever.  In any
    case, if we like inlining recursive stuff, it should be done
    within the recursive function itself to get the algorithm
    recursion depth win.

    EXTRACT_VECTOR_ELT of an INSERT_VECTOR_ELT may have the same index, but the

    The local register allocator has to spill dirty callee saved registers before a
    call that might throw. The landing pad assumes that all registers are in stack
    slots.

    We used to spill those dirty CSRs after the call, and the stack slots would be
    wrong when arriving at the landing pad.

    Reject really weird coalescer case when trying to merge identical subregisters
    of different register classes. e.g.

      %reg1048:3<def> = EXTRACT_SUBREG %RAX<kill>, 3

    Where %reg1048 is a GR32 register. This is not impossible to handle, but it is
    pretty hard and very rare.

    This should unbreak the dragonegg builder.

Date:   Wed Apr 28 19:58:07 2010 +0000

    Rework global alignment computation again.  Now we do round up
    alignment of globals to the preferred alignment, but only when
    there is no section specified on the global (by far the common
    case).

    Recompute kill flags from live intervals after coalescing instead of trying to
    update them. Computing kill flags is notoriously difficult, and the coalescer
    would get it wrong sometimes, and it would completely skip physical registers.

    Now we simply remove kill flags based on the live intervals after coalescing.
    This is a few percent slower, but now we get correct kill flags for physical
    registers after coalescing.

    Teach X86FloatingPoint that a register can be killed multiple times by the same
    instruction.

    This instruction would crash the pass:

      INLINEASM <es:foo $0 $1>, 9, %FP0<kill>, 9, %FP0<kill>, 14, %EFLAGS<earlyclobber,def,dead>

    Now it doesn't.

    Rather than having a ton of patterns for double shift instructions, e.g. SHLD16rrCL, just perform custom dag combine to form x86 specific dag so they match to the same pattern. This also makes sure later dag combine do not cause isel to miss them (e.g. promoting i16 to i32).

    on darwin empty functions need to codegen into something of non-zero length,
    otherwise labels get incorrectly merged.  We handled this by emitting a
    ".byte 0", but this isn't correct on thumb/arm targets where the text segment
    needs to be a multiple of 2/4 bytes.  Handle this by emitting a noop.  This
    is more gross than it should be because arm/ppc are not fully mc'ized yet.

    When checking whether the special handling for an addrec increment which
    doesn't dominate the header is needed, don't check whether the increment
    expression has computable loop evolution. While the operands of an
    addrec are required to be loop-invariant, they're not required to
    dominate any part of the loop. This fixes PR6914.

Author: Dan Gohman <gohman@apple.com>
Date:   Sun Apr 25 00:12:20 2010 +0000

    Fix an autoconf bug: The second argument to AC_LANG_PROGRAM is code that
    gets placed inside a main function, and should not itself be a main
    function. This is silently hidden in GCC-hosted builds because the
    inner main looks like a nested function declaration, which GCC supports.
    In builds with compilers which do not support nested functions (by default),
    this was causing an error, which caused these autoconf checks to fail,
    leaving their options disabled.

    This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu
    llvm-gcc selfhost builds, among other things.

    This also includes a regenerated configure, as the diff is small and telling.

    ScalarEvolution support for <= and >= loops.

    Also, generalize ScalarEvolutions's min and max recognition to handle
    some new forms of min and max that this change makes more common.

    The inliner was choosing to not consider call sites
    that appear in the SCC as a result of inlining as candidates
    for inlining.  Change this so that it *does* consider call
    sites that change from being indirect to being direct as a
    result of inlining.  This allows it to completely
    "devirtualize" the testcase.

    Add an initial description of a new concept: trap values, and change
    the definition of the nsw and nuw flags to make use of it.

    nsw was introduced to help optimizers answer yes to the following:

      // Can we change i from i32 to i64 to eliminate the cast inside the loop?
      for (int i = 0; i < n; ++i) A[i] *= 0.1;

      // Can we assume that this loop will eventually terminate?
      for (int i = 0; i <= n; ++i) A[i] *= 0.1;

    In its current form, it isn't truly sufficient for either.

    In the first case, if the increment overflows, it'll still have some
    valid i32 value; sign-extending it will produce a value which is 33
    homogeneous sign bits trailed by 31 independent undef bits. If i is
    promoted to i64, it won't have those same values when it reaches that
    point. (The compiler could recover here by reasoning about how i is
    used by the load, but that's a lot more complicated and isn't always
    possible.)

    In the second case, there is no value for i which will be greater than
    n, so having the increment return undef on overflow doesn't help.

    Trap values are a formalization of some existing concepts that we have
    about LLVM IR, and give the optimizers a better basis for answering yes
    to both questions above.

    when inlining something like this:

    define void @f3(void (i8*)* %__f) ssp {
    entry:
      call void %__f(i8* undef)
      unreachable
    }

    define void @f4(i8* %this) ssp align 2 {
    entry:
      call void @f3(void (i8*)* @f2) ssp
      ret void
    }

    The inliner is turning the indirect call to %__f into a direct
    call to F2.  Make the call graph more precise when this happens.

    The inliner doesn't revisit call sites introduced by inlining,
    so there isn't an easy way to test for this, but a more precise
    callgraph is a good thing.

    add a DEBUG call so that -debug lists when CGSCCPM iterates.

    Fix RefreshCallGraph to use CGN->replaceCallEdge instead of hand
    rolling its own loop.  replaceCallEdge properly maintains the
    reference counts of the nodes, fixing a crash exposed by the
    iterative callgraph stuff.

    Move PHINodesToUpdate out of SelectionDAGBuilder and into
    FunctionLoweringInfo, as it isn't SelectionDAG-specific. This isn't
    completely natural, as PHI node state is not per-function but rather
    per-basic-block, however there's currently no other convenient
    per-basic-block state to group it with.

    Run LiveVariables instead of computing liveness locally in -regalloc=fast.

    This actually makes everything slower, but the plan is to have isel add <kill>
    flags the way it is already adding <dead> flags. Then LiveVariables can be
    removed again.

    When ignoring the time spent in LiveVariables, -regalloc=fast is now twice as
    fast as -regalloc=local.

Date:   Wed Apr 21 18:02:42 2010 +0000

    Add fast register allocator, enabled with -regalloc=fast.

    So far this is just a clone of -regalloc=local that has been lobotomized to run
    25% faster. It drops the least-recently-used calculations, and is just plain
    stupid when it runs out of registers.

    The plan is to make this go even faster for -O0 by taking advantage of the short
    live intervals in unoptimized code. It should not be necessary to calculate
    liveness when most virtual registers are killed 2-3 instructions after they are
    born.

    Implement (but don't enable) PR6724 and rdar://6295824.  In short,
    we have RefreshCallGraph detect when a function pass devirtualizes
    a call, and have CGSCCPassMgr iterate (up to a count) when this
    happens.  This allows (in the example) GVN to devirtualize the
    call in foo, then the inliner to inline it away.

    This is not currently enabled because I haven't done any analysis
    on the (potentially substantial) code size or performance impact of
    doing this, and guess what, it exposes callgraph updating bugs in
    various passes.  This is progress though, and you can play with it
    by passing -max-cg-scc-iterations=5 to opt.

    Revert r101471. For tight recursive functions which have multiple
    recursive callsites, inlining can reduce the number of calls by
    exponential factors, as it does in
    MultiSource/Benchmarks/Olden/treeadd. More involved heuristics
    will be needed.

    teach the x86 address matching stuff to handle
    (shl (or x,c), 3) the same as (shl (add x, c), 3)
    when x doesn't have any bits from c set.

    This finishes off PR1135.  Before we compiled the block to:
    to:

    LBB0_3:                                 ## %bb
    	cmpb	$4, %dl
    	sete	%dl
    	addb	%dl, %cl
    	movb	%cl, %dl
    	shlb	$2, %dl
    	addb	%r8b, %dl
    	shlb	$2, %dl
    	movzbl	%dl, %edx
    	movl	%esi, (%rdi,%rdx,4)
    	leaq	2(%rdx), %r9
    	movl	%esi, (%rdi,%r9,4)
    	leaq	1(%rdx), %r9
    	movl	%esi, (%rdi,%r9,4)
    	addq	$3, %rdx
    	movl	%esi, (%rdi,%rdx,4)
    	incb	%r8b
    	decb	%al
    	movb	%r8b, %dl
    	jne	LBB0_1

    Now we produce:

    LBB0_3:                                 ## %bb
    	cmpb	$4, %dl
    	sete	%dl

    	movzbl	%dl, %edx
    	movl	%esi, (%rdi,%rdx,4)
    	movl	%esi, 8(%rdi,%rdx,4)
    	movl	%esi, 4(%rdi,%rdx,4)
    	movl	%esi, 12(%rdi,%rdx,4)
    	incb	%r8b
    	decb	%al
    	movb	%r8b, %dl

    Because of the EMMS problem, right now we have to support
    user-defined operations that use MMX register types, but
    the compiler shouldn't generate them on its own.  This adds
    a Synthesizable abstraction to represent this, and changes
    the vector widening computation so it won't produce MMX types.
    (The motivation is to remove noise from the ABI compatibility
    part of the gcc test suite, which has some breakage right now.)

    When MachineLICM is hoisting a physical register after regalloc, make sure the
    register is not killed in the loop.

    This fixes 188.ammp on ARM where the post-ra scheduler would grab a register
    that looked available but wasn't.

    A testcase would be huge and fragile, sorry.

    Bill's change in r95336 broke empty aggregates embedded
    in other types.  fix this by only bumping zero-byte globals
    up to a single byte if the *entire global* is zero size,
    fixing PR6340.

    This also fixes empty arrays etc to be handled correctly,
    and only does this on subsection-via-symbols targets (aka
    darwin) which is the only place where this matters.

    Fix tests for Neon load/store intrinsics to match the i8* types expected by
    the intrinsics.  The reason for those i8* types is that the intrinsics are
    overloaded on the vector type and we don't have a way to declare an intrinsic
    where one argument is an overloaded vector type and another argument is a
    pointer to the vector element type.  The bitcasts added here will match what
    the frontend will typically generate when these intrinsics are used.

    Use const qualifiers with TargetLowering. This eliminates several
    const_casts, and it reinforces the design of the Target classes being
    immutable.

    SelectionDAGISel::IsLegalToFold is now a static member function, because
    PIC16 uses it in an unconventional way. There is more room for API
    cleanup here.

    And PIC16's AsmPrinter no longer uses TargetLowering.

    reenable r101565, removing a problematic assertion.
    CGSCC can delete nodes in regions of the callgraph that
    have already been visited.  If new CG nodes are allocated
    to the same pointer, we shouldn't abort, just handle it
    correctly by assigning a new number.  This should restore
    stability by removing invalidated pointers that *will* be
    reused from the densemap in the iterator.

    Re-commit my previous SSAUpdater changes.  The previous version naively tried
    to determine where to place PHIs by iteratively comparing reaching definitions
    at each block.  That was just plain wrong.  This version now computes the
    dominator tree within the subset of the CFG where PHIs may need to be placed,
    and then places the PHIs in the iterated dominance frontier of each definition.
    The rest of the patch is mostly the same, with a few more performance
    improvements added in.

    Multiclass LdStCop was using pre-UAL syntax LDC<c>L for the L fragment.  Changed
    to the UAL syntax of LDCL<c>, instead.

    Add a test case for this change which also tests the removal of assert() from
    printAddrMode2OffsetOperand().

    rotate CallInst operands, i.e. move callee to the back

    the motivation for this patch are laid out in my mail to llvm-commits:
    more efficient access to operands and callee, faster callgraph-construction,
    smaller compiler binary

    The JIT calls TidyLandingPads to tidy up the landing pads. However, because the
    JIT doesn't use the MC back-end asm printer to emit labels that it uses, the
    section for the MCSymbol is never set. And thus the MCSymbol for the EH label
    isn't marked as "defined". Because of that, TidyLandingPads removes the needed
    landing pads from the JIT output. This breaks EH for every JIT program.

    This is a work-around for this limitation. We pass in the label locations
    map. If the label has a non-zero value, then it was "emitted" by the JIT and
    TidyLandingPads shouldn't remove that label.

    A nicer solution would be to mark the MCSymbol as "used" by the JIT and not rely
    upon the section being set to determine if it's defined or not.

    Adding support for dag combiner to promote operations for profit. This requires target specific queries. For example, x86 should promote i16 to i32 when it does not impact load folding.

    Avoid sinking machine instructions into a loop.

    MachineLoopInfo is already available when MachineSinking runs, so the check is
    free.

    There is no test case because it would require a critical edge into a loop, and
    CodeGenPrepare splits those. This check is just to be extra careful.

    ARM SelectDYN_ALLOC should emit a copy from SP rather than referencing SP directly. In cases where there are two dyn_alloc in the same BB it would have caused the old SP value to be reused and badness ensues. rdar://7493908

    teach codegen to turn trunc(zextload) into load when possible.
    This doesn't occur much at all, it only seems to formed in the case

    Implement rdar://7860110 (also in target/readme.txt) narrowing
    a load/or/and/store sequence into a narrower store when it is
    safe.  Daniel tells me that clang will start producing this sort
    of thing with bitfields, and this does  trigger a few dozen times
    on 176.gcc produced by llvm-gcc even now.

    This compiles code like CodeGen/X86/2009-05-28-DAGCombineCrash.ll
    into:

            movl    %eax, 36(%rdi)

    instead of:

            movl    $4294967295, %eax       ## imm = 0xFFFFFFFF
            andq    32(%rdi), %rax
            shlq    $32, %rcx
            addq    %rax, %rcx
            movq    %rcx, 32(%rdi)

    and each of the testcases into a single store.  Each of them used
    to compile into craziness like this:

    _test4:
    	movl	$65535, %eax            ## imm = 0xFFFF
    	andl	(%rdi), %eax
    	shll	$16, %esi

    Fixed another assert exposed by fuzzing.  The utility function getRegisterEnum()
    was asserting because the (RegClass, RegNum) combination doesn't make sense from
    an encoding point of view.

    Since getRegisterEnum() is used all over the place, to change the code to check
    for encoding error after each call would not only bloat the code, but also make
    it less readable.  An Err flag is added to the ARMBasicMCBuilder where a client
    can set a non-zero value to indicate some kind of error condition while building
    up the MCInst.  ARMBasicMCBuilder::BuildIt() checks this flag and returns false
    if a non-zero value is detected.

    Fixed a nasty layering violation in the edis source
    code.  It used to #include the enhanced disassembly
    information for the targets it supported straight
    out of lib/Target/{X86,ARM,...} but now it uses a
    new interface provided by MCDisassembler, and (so
    far) implemented by X86 and ARM.

    Also removed hacky #define-controlled initialization
    of targets in edis.  If clients only want edis to
    initialize a limited set of targets, they can set
    --enable-targets on the configure command line.

    Teach MachineSinking to handle easy critical edges.

    Sometimes it is desirable to sink instructions along a critical edge:

    x = ...
    if (a && b) ...
    else use(x);

    The 'a && b' condition creates a critical edge to the else block, but we still
    want to sink the computation of x into the block. The else block is dominated by
    the parent block, so we are not pushing instructions into new code paths.

    Micro-optimization:

    If we have this situation:

        jCC  L1
        jmp  L2
    L1:
      ...
    L2:
      ...

    We can get a small performance boost by emitting this instead:

        jnCC L2
    L1:
      ...
    L2:
      ...

    This testcase shows an example of this:

    Suppress LinearFunctionTestReplace when the computed backedge-taken
    expression is a UDiv and it doesn't appear that the UDiv came from
    the user's source.

    ScalarEvolution has recently figured out how to compute a tripcount
    expression for the inner loop in
    SingleSource/Benchmarks/Shootout/sieve.c, using a udiv. Emitting a
    udiv instruction dramatically slows down the enclosing loop.

    Second try at integrating the edis tester.  This
    time I use the LIBS variable, which is not subject
    to a %.a -> -l% transformation, to link llvm-mc
    against libEnhancedDisassembly.

    llvm-mc -edis works the same as llvm-mc
    -disassemble, but outputs tokens and operands.

commit 27d3ecbfe2dc3048fe5fb8abf9d4cdd95b5cefd6
Author: Johnny Chen <johnny.chen@apple.com>
Date:   Mon Apr 12 18:46:53 2010 +0000

    Fixed a crasher in arm disassembler within ARMInstPrinter.cpp after calling
    ARM_AM::getSoImmVal(V) with a legitimate so_imm value: #245 rotate right by 2.
    Introduce ARM_AM::getSOImmValOneOrNoRotate(unsigned Arg) which is called from
    ARMInstPrinter.cpp's printSOImm() function, replacing ARM_AM::getSOImmVal(V).

    performing, rather than just checking hasNo{Signed,Unsigned}Wrap, since
    those flags are for a different computation. This fixes a bug that

    Teach IndVarSimplify how to eliminate comparisons involving induction
    variables. For example, with code like this:

      for (i=0;i<n;++i)
        if (i<n)
          x[i] = 0;

    IndVarSimplify will now recognize that i is always less than n inside
    the loop, and eliminate the if.

    configure: Fix default value for optimize_option, I messed up the test condition
    in r86005 and unintentionally changed the default from -O3 to -O2.

     - It's odd the things automated perf testing turns up! :)

     - Also, the configure diff is messed up slightly. It looks like someone either
       didn't regenerate configure correctly (or I didn't), or autoconf has some
       funnyness in it. Eric, any ideas?

    This has been at -O2 for so long, that I am slightly nervous that this change
    will uncover miscompiles of LLVM on other systems. If that is the case, I think
    we should just set the default universally at -O3, and let developers/vendors
    use -O3 if they want it and have tested it.

    If all the bit positions are not specified; do not decode the instructions.
    We are bound to fail!  For proper disassembly, the well-known encoding bits
    of the instruction must be fully specified.

    This also removes pseudo instructions from considerations of disassembly,
    which is a better design and less fragile than the name matchings.

Date:   Fri Apr 9 00:11:15 2010 +0000

    Bugfixes for edis.  Code to initialize instruction
    state was being executed too lazily, and the LLVM
    assembly syntax for the disassembler was not being
    written into the proper disassembler state variable.

    convert a report_fatal_error that I was able to trigger into a nice error
    so the user at least knows what inline asm is a problem.  For example:

    pr8788-1.c:14:10: note: generated from here
        asm ("\n" : "+r" (stack->regs)

    INLINEASM <es:abc incl    ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>

    Now we generate this:

    $ clang asm.c -c -o t.o
    error: invalid operand in inline asm: 'incl    ${0:Z}'
    asm.c:3:12: note: generated from here
      __asm__ ("incl    %Z0" : "+r" (X));
               ^
    1 error generated.

    This is much better but still admittedly not great ("why" is the operand
    invalid??), codegen should try harder with its diagnostics :)

Author: Dan Gohman <gohman@apple.com>
Date:   Wed Apr 7 22:27:08 2010 +0000

    Generalize IVUsers to track arbitrary expressions rather than expressions
    explicitly split into stride-and-offset pairs. Also, add the
    ability to track multiple post-increment loops on the same expression.

    This refines the concept of "normalizing" SCEV expressions used for
    to post-increment uses, and introduces a dedicated utility routine for
    normalizing and denormalizing expressions.

    This fixes the expansion of expressions which are post-increment users
    of more than one loop at a time. More broadly, this takes LSR another
    step closer to being able to reason about more than one loop at a time.

Author: Sean Callanan <scallanan@apple.com>
Date:   Wed Apr 7 21:42:19 2010 +0000

    Fixed a bug where the disassembler would allow an immediate
    argument that had to be between 0 and 7 to have any value,
    firing an assert later in the AsmPrinter.  Now, the
    disassembler rejects instructions with out-of-range values
    for that immediate.

    VHADD differs from VHSUB at least on A9 - the former reads both operands in the second cycle, while the latter reads second operand in first cycle. Introduce new itin classes to catch this behavior. Whether this is true for A8 as well is WIP.

Author: Chris Lattner <sabre@nondot.org>
Date:   Wed Apr 7 05:20:54 2010 +0000

    Three changes:
    1. Introduce some enums and accessors in the InlineAsm class
       that eliminate a ton of magic numbers when handling inline
       asm SDNode.
    2. Add a new MDNodeSDNode selection dag node type that holds
       a MDNode (shocking!)
    3. Add a new argument to ISD::INLINEASM nodes that hold !srcloc
       metadata, propagating it to the instruction emitter, which
       drops it.

    No functionality change.

    We would return the error without inserting the new instruction
    into the program, so it wouldn't get deallocated, and an abort

    Fix PR6696 and PR6663

    When a frame pointer is not otherwise required, and dynamic stack alignment
    is necessary solely due to the spilling of a register with larger alignment
    requirements than the default stack alignment, the frame pointer can be both
    used as a general purpose register and a frame pointer. That goes poorly, for
    obvious reasons. This patch brings back a bit of old logic for identifying
    the use of such registers and conservatively reserves the frame pointer
    during register allocation in such cases.

    For now, implement for X86 only since it's 32-bit linux which is hitting this,
    and we want a targeted fix for 2.7. As a follow-on, this will be expanded
    to handle other targets, as theoretically the problem could arise elsewhere
    as well.

    Revise debug info machinery to digest nested functions and classes.

    A certain GDB testsuite case (local.cc) has a function nested inside a
    class nested inside another function.  GCC presents the innermost
    function to llvm-convert first.  Heretofore, the debug info mistakenly
    placed the inner function at module scope.  This patch walks the GCC
    context links and instantiates the outer class and function so the
    debug info is properly nested.  Radar 7426545.

    add .o file writing for inline asm in llc.  Here's a silly

    <inline asm>:1:2: error: unrecognized instruction

    LLVM ERROR: Error parsing inline asm

    Only problem seems to be that the parser finalizes OutStreamer
    at the end of the first inline asm, which isn't what we want.
    For example:

    $ cat asm.c
    int foo(int X) {
     __asm__ ("incl    %0" : "+r" (X));
     return X;
    }
    $ clang asm.c -S -o - -emit-llvm | llc

    	movl	%edi, (%rsp)
    	movl	%edi, %eax
    	## InlineAsm Start
    	incl    %eax
    	## InlineAsm End
    	movl	%eax, (%rsp)
    	movl	%eax, 4(%rsp)
    	addq	$8, %rsp
    	ret
    $ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o

    fix a really nasty bug that Evan was tracking in SCCP.  When resolving
    undefs in branches/switches, we have two cases: a branch on a literal
    undef or a branch on a symbolic value which is undef.  If we have a
    literal undef, the code was correct: forcing it to a constant is the
    right thing to do.

    If we have a branch on a symbolic value that is undef, we should force
    the symbolic value to a constant, which then makes the successor block
    live.  Forcing the condition of the branch to being a constant isn't
    safe if later paths become live and the value becomes overdefined.  This
    is the case that 'forcedconstant' is designed to handle, so just use it.

    This fixes rdar://7765019 but there is no good testcase for this, the
    one I have is too insane to be useful in the future.

    Introduce MaybeOwningPtr, a smart pointer that may (or may not) have
    ownership over the pointer it contains. Useful when we want to
    communicate ownership while still having several clients holding on to
    the same pointer *without* introducing reference counting.

    hopefully sate the clang self host build, which is apparently
    instantiating some folding set stuff that GCC isn't, requiring
    some types to not be incomplete.

    I don't know if clang is right or wrong, but unbreaking the
    bot is goodness.  Here's the broken build:

    The disassembler impl. of MCDisassembler::getInstruction() was using the pattern
      uint32_t insn;
      MemoryObject.readBytes(Address, 4, (uint8_t*)&insn, NULL)

    to read 4 bytes of memory contents into a 32-bit uint variable.  This leaves the
    interpretation of byte order up to the host machine and causes PPC test cases of
    arm-tests, neon-tests, and thumb-tests to fail.  Fixed to use a byte array for
    reading the memory contents and shift the bytes into place for the 32-bit uint
    variable in the ARM case and 16-bit halfword in the Thumb case.

    Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field.

    When a target instruction wants to set target-specific flags, it should simply
    set bits in the TSFlags bit vector defined in the Instruction TableGen class.

    This works well because TableGen resolves member references late:

    class I : Instruction {
      AddrMode AM = AddrModeNone;
      let TSFlags{3-0} = AM.Value;
    }

    let AM = AddrMode4 in
    def ADD : I;

    TSFlags gets the expected bits from AddrMode4 in this example.

    Momentous day: remove the "O" member from AsmPrinter.  Now all
    "asm printering" happens through MCStreamer.  This also
    Streamerizes PIC16 debug info, which escaped my attention.

    now that all operand printing happens to specified streams, we can
    print function level inline asm with EmitInlineAsm instead of writing
    it directly to "O".

    add integer overflow check for the fp induction variable

    have rejects because they would be miscompiled in the

    The remaining issue with this is that we don't check that
    the branch causes us to exit the loop if it fails, so we
    don't actually know if we remain in bounds.

    Add special case bitcode support for DebugLoc.  This avoids
    having the bitcode writer materialize mdnodes for all the
    debug location tuples when writing out the bc file and
    stores the information in a more compact form.  For example,
    the -O0 -g bc file for combine.c in 176.gcc shrinks from
    739392 to 512096 bytes.

    This concludes my planned short-term debug info work.

    Ok, third time's the charm.  No changes from last time except the CMake
    source addition.  Apparently the buildbots were wrong about failures.

    ---

    Add some switches helpful for debugging:

    -print-before=<Pass Name>

    Dump IR before running pass <Pass Name>.

    -print-before-all

    Dump IR before running each pass.

    -print-after-all

    Dump IR after running each pass.

    These are helpful when tracking down a miscompilation.  It is easy to
    get IR dumps and do diffs on them, etc.

    To make this work well, add a new getPrinterPass API to Pass so that
    each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass
    suitable for dumping out the kind of object the Pass works on.

    Second try of initial ARM/Thumb disassembler check-in.  It consists of a tablgen
    backend (ARMDecoderEmitter) which emits the decoder functions for ARM and Thumb,
    and the disassembler core which invokes the decoder function and builds up the
    MCInst based on the decoded Opcode.

    Switch the code generator (except the JIT) onto the new DebugLoc
    representation.  This eliminates the 'DILocation' MDNodes for
    file/line/col tuples from -O0 -g codegen.

    This remove the old DebugLoc class, making it a typedef for DebugLoc,
    I'll rename NewDebugLoc next.

    I didn't update the JIT to use the new apis, so it will continue to
    work, but be as slow as before.  Someone should eventually do this
    or, better yet, rip out the JIT debug info stuff and build the JIT

    Let's try this again.  Re-apply 100143 including an apparent missing
    <string> include.  For some reason the buildbot choked on this while my
    builds did not.  It's probably due to a difference in system headers.

    ---

    Add some switches helpful for debugging:

    -print-before=<Pass Name>

    Dump IR before running pass <Pass Name>.

    -print-before-all

    Dump IR before running each pass.

    -print-after-all

    Dump IR after running each pass.

    These are helpful when tracking down a miscompilation.  It is easy to
    get IR dumps and do diffs on them, etc.

    To make this work well, add a new getPrinterPass API to Pass so that
    each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass
    suitable for dumping out the kind of object the Pass works on.

    Various improvements to MemoryBuffer::getFile:

    - Use a RAII object to close the FD.
    - Use sys::StrError instead of thread-unsafe strerror calls.
    - Recover gracefully if read returns zero. This works around an issue on
      DragonFlyBSD where /dev/null has an st_size of 136 but we can't read 136 bytes
      from it.

    Introduce ImmutableCallSite, useful for contexts where no mutation
    is necessary. Inherits from new templated baseclass CallSiteBase<>
    which is highly customizable. Base CallSite on it too, in a configuration
    that allows full mutation.
    Adapt some call sites in analyses to employ ImmutableCallSite.

    switch IRBuilder to use NewDebugLoc for locations instead
    of raw mdnodes.  This allows frontends to specify debug
    locations without ever creating an MDNode for the DILocation.

    This requires a corresponding clang/llvm-gcc change which
    I'll try to commit as simultaneously as possible.

    Fix sdisel memcpy, memset, memmove lowering:
    1. Makes it possible to lower with floating point loads and stores.
    2. Avoid unaligned loads / stores unless it's fast.
    3. Fix some memcpy lowering logic bug related to when to optimize a
       load from constant string into a constant.
    4. Adjust x86 memcpy lowering threshold to make it more sane.
    5. Fix x86 target hook so it uses vector and floating point memory
       ops more effectively.

    Switch the representation of the location in instruction from
    being a TrackingVH<MDNode> to a NewDebugLoc, shrinking
    sizeof(Instruction) a lot, and providing clients the ability
    to deal with locations in terms of NewDebugLoc instead of
    having to deal with Metadata.  This is still fully compatible
    with all clients that *do* use MDNodes for everything of
    course.

    No functionality change.

    Add a new "NewDebugLoc" class which will eventually replace DebugLoc,
    and will replace the 'DbgInfo' member in Instruction.

    The benefit of NewDebugLoc is that it is compact (8 bytes vs 12/24
    bytes for the DbgInfo member in Instruction on a 32/64 bit system),
    it means that we will end up not having to allocate MDNodes to
    represent the "DILocations" in common cases of -O0 -g, and it is
    much more efficient to get things out of than the MDNode.

    Fix a nasty dangling-pointer heisenbug that could
    generate wrong code pretty much anywhere AFAICT.
    A case that hits the bug reproducibly is impossible,
    but the situation was like this:
    Addr = ...
    Store -> Addr
    Addr2 = GEP , 0, 0
    Store -> Addr2
    Handling the first store, the code changed replaced Addr
    with a sunkaddr and deleted Addr, but not its table
    entry.  Code in OptimizedBlock replaced Addr2 with a
    bitcast; if that happened to reuse the memory of Addr,
    the old table entry was erroneously found when handling
    the second store.

    Fix a major source of compile-time slowness at -O0 -g by optimizing
    the storage of !dbg metadata kinds in the instruction themselves.
    The on-the-side hash table works great for metadata that not-all
    instructions get, or for metadata that only exists when optimizing.
    But when compile-time is everything, it isn't great.

    I'm not super thrilled with the fact that this plops a TrackingVH in
    Instruction, because it grows it by 3 words.  I'm investigating
    alternatives, but this should be a step in the right direction in any
    case.

    Introduce another Reset() method in BumpPtrAllocator that calls a destructor
    on all objects it has allocated, if they are all of the same size and alignment.
    Use this to destruct all VNInfos allocated in LiveIntervalAnalysis (PR6653).

    valnos is not reliable for this purpose, as seen in r99400
    (which still leaked, and sometimes caused double frees).

    A more general (and simpler!) implementation of r99671. It performs a similar
    transform. I.e., if a clean-up eh.selector call dominates the invoke of an
    _Unwind_Resume_or_Rethrow, then we convert the eh.selector into a
    catch-all. This patch, however, uses the DominatorTree information, and doesn't
    go through the whole rigmarole of starting at the eh.exception call, finding the
    corresponding URoR and eh.selector calls, and trying to trace through any number
    of instruction types to get to them.

    From Kalle Raiskila:

    "the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions:
    -in vararg handling, registers are marked to be live, to not confuse the register scavenger
    -function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the register scavenger emergency spill slot, which is not used as there is no stack."

commit 2b652a2062baa59803db3cd720ea6645f5b48385
Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Mar 29 02:02:45 2010 +0000

    Switch pattern sorting predicate from stable sort -> sort, it
    doesn't need to be stable because the patterns are fully ordered.

    Add a first level sort predicate that orders patterns in this
    order:  1) scalar integer operations 2) scalar floating point
    3) vector int 4) vector float.  This is a trivial sort on their
    top level pattern type so it is nice and transitive.  The
    benefit of doing this is that simple integer operations are
    much more common than insane vector things and isel was trying
    to match the big complex vector patterns before the simple
    ones because the complexity of the vector operations was much
    higher.  Since they can't both match, it is best (for compile
    time) to try the simple integer ones first.

    This cuts down the # failed match attempts on real code by
    quite a bit, for example, this reduces backtracks on crafty
    (as a random example) from 228285 -> 188369.

    Check in a (disabled) failed attempt to improve the ordering of
    patterns within the generated matcher.  This works great except
    that the sort fails because the relation defined isn't
    transitive.  I have a much simpler solution coming next, but want
    to archive the code.

    Fix use-of-uninitialized value when RWX memory can't be allocated (PR6701).

    SELinux doesn't allow 'execmem', returning MAP_FAILED and 'Permission denied'
    for mmap or RWX memory. In this case AllocateRWX was returning a MemoryBlock
    with uninitialized fields, which sometimes caused crashes.

    This patch initializes MemoryBlock fields to 0, so that the RWX-failure check
    works.
    It doesn't fix the SELinux 'execmem' issues though (the JIT will not work when
    SELinux is in enforcing mode).

    and those derived from them.  These are obnoxious because
    they were written as: PatLeaf<(bitconvert).  Not having an

    count matching up with what was required (in this case,
    bitconvert always requires an operand!)

    teach tblgen to allow patterns like (add (i32 (bitconvert (i32 GPR))), 4),
    transforming it into (add (i32 GPR), 4).  This allows us to write type
    generic multi patterns and have tblgen automatically drop the bitconvert
    in the case when the types align.  This allows us to fold an extra load
    in the changed testcase.

    fix a long standing fixme, which required fixing a bunch of other
    issues to get here.  We now trim the result type list of the
    CompleteMatch or MorphNodeTo operation to be the same size as the
    thing we're matching.  this means that if you match (add GPR, GPR)
    with an instruction that produces a normal result and a flag that
    we now trim the result in tblgen instead of having to do it
    dynamically.  This exposed a bunch of inconsistencies in result
    counting that happened to be getting lucky since the days of the
    old isel.

    If we mark clean-ups as clean-ups, then it could break when inlining through an
    'invoke' instruction. You will get a situation like this:

    bb:
      %ehptr = eh.exception()
      %sel = eh.selector(%ehptr, @per, 0);

    ...

    bb2:
      invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad

    lpad:
      ...

    The unwinder will see the %sel call as a clean-up and, if it doesn't have a
    catch further up the call stack, it will skip running it. But there *is* another
    catch up the stack -- the catch for the %lpad. However, we can't see that. This
    is fixed in code-gen, where we detect this situation, and convert the "clean-up"
    selector call into a "catch-all" selector call. This gives us the correct
    semantics.

    Feel free to LOL at the -before numbers, if you like.

    I am a little surprised we make more than 2 relaxation passes. It's pretty
    trivial for us to do relaxation out-of-order if that would give a speedup.

    Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain crossings.

    On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a register
    in a different domain than where it was defined. Some instructions have
    equvivalents for different domains, like por/orps/orpd.

    The SSEDomainFix pass tries to minimize the number of domain crossings by
    changing between equvivalent opcodes where possible.

    This is a work in progress, in particular the pass doesn't do anything yet. SSE
    instructions are tagged with their execution domain in TableGen using the last
    two bits of TSFlags. Note that not all instructions are tagged correctly. Life
    just isn't that simple.

    The SSE execution domain issue is very similar to the ARM NEON/VFP pipeline
    issue handled by NEONMoveFixPass. This pass may become target independent to
    handle both.

    Fixed spurious warning problem noticed by Daniel Dunbar.  The configure script
    now configures prerequisite projects individually but also ignores them in the
    big project switch statement to avoid the incorrect warning.

    Change tblgen to emit FOOISD opcode names as two
    bytes instead of one byte.  This is important because
    we're running up to too many opcodes to fit in a byte
    and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE
    making the numbering sparse.  This just bites the
    bullet and bloats out the table.  In practice, this
    increases the size of the x86 isel table from 74.5K
    to 76K.  I think we'll cope :)

    This fixes rdar://7791648

    Fix evil TableGen bug in template parameters with defaults.

    If a TableGen class has an initializer expression containing an X.Y subexpression,
    AND X depends on template parameters,
    AND those template parameters have defaults,
    AND some parameters with defaults are beyond position 1,
    THEN parts of the initializer expression are evaluated prematurely with the default values when the first explicit template parameter is substituted, before the remaining explicit template parameters have been substituted.

    eliminate a bunch more parallels now that scheduling
    handles dead implicit results more aggressively.  More
    to come, I think this is now just a data entry problem.

    git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99486 91177308-0d34-0410-b5e6-96231b3b80d8

    Make the NDEBUG assertion stronger and more clear what is
    happening.

    Enhance scheduling to set the DEAD flag on implicit defs
    more aggressively.  Before, we'd set an implicit def operand
    to dead if it were present in the SDNode corresponding to
    the machineinstr but had no use.  Now we do it in this case
    AND if the implicit def does not exist in the SDNode at all.

    This exposes a couple of problems: one is the FIXME, which
    causes a live intervals crash on CodeGen/X86/sibcall.ll.
    The second is that it makes machinecse and licm more
    aggressive (which is a good thing) but also exposes a case
    where licm hoists a set0 and then it doesn't get resunk.

    Talking to codegen folks about both these issues, but I need
    this patch in in the meantime.

    Change how dbg_value sdnodes are converted into machine instructions. Their placement should be determined by the relative order of incoming llvm instructions. The scheduler will now use the SDNode ordering information to determine where to insert them. A dbg_value instruction is inserted after the instruction with the last highest source order and before the instruction with the next highest source order. It will optimize the placement by inserting right after the instruction that produces the value if they have consecutive order numbers.

    Here is a theoretical example that illustrates why the placement is important.

    tmp1 =
    store tmp1 -> x
    ...
    tmp2 = add ...
    ...
    call
    ...
    store tmp2 -> x

    Now mem2reg comes along:

    tmp1 =
    dbg_value (tmp1 -> x)
    ...
    tmp2 = add ...
    ...
    call
    ...
    dbg_value (tmp2 -> x)

    When the debugger examine the value of x after the add instruction but before the call, it should have the value of tmp1.

    Furthermore, for dbg_value's that reference constants, they should not be emitted at the beginning of the block (since they do not have "producers").

    This patch also cleans up how SDISel manages DbgValue nodes. It allow a SDNode to be referenced by multiple SDDbgValue nodes. When a SDNode is deleted, it uses the information to find the SDDbgValues and invalidate them. They are not deleted until the corresponding SelectionDAG is destroyed.

    Disable folding loads into tail call in 32-bit PIC mode. It can introduce illegal code like this:

            addl    $12, %esp
            popl    %esi
            popl    %edi
            popl    %ebx
            popl    %ebp
            jmpl    *__Block_deallocator-L1$pb(%esi)  # TAILCALL

    The problem is the global base register is assigned GR32 register class. TCRETURNmi needs the registers making up the address mode to have the GR32_TC register class.

    The *proper* fix is for X86DAGToDAGISel::getGlobalBaseReg() to return a copy from the global base register of the machine function rather than returning the register itself. But that has the potential of causing it to be coalesced to a more restrictive register class: GR32_TC. It can introduce additional copies and spills. For something as important the PIC base, it's not worth it especially since this is not an issue on 64-bit.

    Fix memory leak in liveintervals: the destructor for VNInfos must be called,
    otherwise the SmallVector it contains doesn't free its memory.
    In most cases LiveIntervalAnalysis could get away by not calling the destructor,
    because VNInfos are bumpptr-allocated, and smallvectors usually don't grow.
    However when the SmallVector does grow it always leaks.

    This is the valgrind shown leak from the original testcase:

    Switch SDTUnaryArithWithFlags to being modeled as a two-result
    ISD node.  The only change in the generated isel code are comments
    like:

    <                 // Src: (X86dec_flag:i16 GR16:i16:$src)
    ---
    >                 // Src: (X86dec_flag:i16:i32 GR16:i16:$src)

    because now it knows that X86dec_flag returns both an i16 (for the result)
    and an i32 (for EFLAGS) in this case.  Wewt.

    Fix VLDMQ and VSTMQ instructions to use the correct encoding and address modes.
    These instructions are only needed for codegen, so I've removed all the
    explicit encoding bits for now; they should be set in the same way as the for
    VLDMD and VSTMD whenever we add encodings for VFP.  The use of addrmode5
    requires that the instructions be custom-selected so that the number of
    registers can be set in the AM5Opc value.

    of runs without leak checking.  We add -vg to the triple for non-checked runs,

    tablegen leaks like a sieve.  This includes some valgrindArgs refactoring.

    Re-commit r98683 ("remove redundant writeback flag from ARM address mode 6")
    with changes to add a separate optional register update argument.  Change all
    the NEON instructions with address register writeback to use it.

    Fix a very bad typo.  Since the register number was off by one, the ARM
    load/store optimizer would incorrectly think that registers D26 and D28
    were consecutive and would generate a VLDM instruction to load them.
    The assembler was not convinced.

    Clear the SCEVExpander's insertion point after making deletions,
    so that the SCEVExpander doesn't retain a dangling pointer as its
    insert position. The dangling pointer in this case wasn't ever used
    to insert new instructions, but it was causing trouble with
    SCEVExpander's code for automatically advancing its insert position
    past debug intrinsics.

    This fixes use-after-free errors that valgrind noticed in
    test/Transforms/IndVarSimplify/2007-06-06-DeleteDanglesPtr.ll and
    test/Transforms/IndVarSimplify/exit_value_tests.ll.

    If call result is in ST0 and it is not being passed to the caller's

    Fixed the encoding problems of the crc32 instructions. All had the Operand size
    override prefix and only the r/m16 forms should have had that.  Also for variant
    one, the AT&T syntax, added suffixes to all forms.  Also added the missing
    64-bit form for 'CRC32 r64, r/m8'.  Plus added test cases for all forms and
    tweaked one test case to add the needed suffixes.

    Stop trying to merge identical jump tables.  This had been inadvertently
    disabled for several months (since svn r88806) and no one noticed.  My fix
    for pr6543 yesterday reenabled it, but broke the ARM port's code for using
    TBB/TBH.  Rather than adding a target hook to disable merging for Thumb2 only,
    I'm just taking this out.  It is not common to have identical jump tables,
    the code we used to merge them was O(N^2), and it only helps code size, not
    performance.

    MC/Mach-O/x86_64: Add relocation support.
     - This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information.
     - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily).
     - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :)

    Set numThreads to 1 by default when Python is older than 2.5.2.

    Python 2.4 always hits this bug: http://bugs.python.org/issue1731717
    when running check-lit on multi-core systems.
    Setting numThreads to 1 makes it slower, but at least the results reported are
    correct.

    Recommit r80858 again (which has been backed out in r80871).

    This time I did a self-hosted bootstrap on Linux x86-64,
    with no problems. Let's see how darwin 64-bit self-hosting
    goes. At the first sign of failure I'll back this out.

    Maybe the valgrind bots give me a hint of what may be wrong
    (it at all).

    Finally change the instruction looking map to be a densemap from
    record* -> instrinfo instead of std::string -> instrinfo.

    This speeds up tblgen on cellcpu from 7.28 -> 5.98s with a debug
    build (20%).

    Bugpoint's default memory limit (100MB) was too low for valgrind, so
    this patch raises the default to 800MB when valgrind's active.  800
    was chosen semi-arbitrarily.

    Now that tblgen can handle matching implicit defs of instructions
    to input patterns, we can fix X86ISD::CMP and X86ISD::BT as taking
    two inputs (which have to be the same type) and *returning an i32*.
    This is how the SDNodes get made in the graph, but we weren't able
    to model it this way due to deficiencies in the pattern language.

    Now we can change things like this:

     def UCOM_FpIr80: FpI_<(outs), (ins RFP80:$lhs, RFP80:$rhs), CompareFP,
    -                  [(X86cmp RFP80:$lhs, RFP80:$rhs),
    -                   (implicit EFLAGS)]>; // CC = ST(0) cmp ST(i)
    +                  [(set EFLAGS, (X86cmp RFP80:$lhs, RFP80:$rhs))]>;

    and fix terrible crimes like this:

    -def : Pat<(parallel (X86cmp GR8:$src1, 0), (implicit EFLAGS)),
    +def : Pat<(X86cmp GR8:$src1, 0),
               (TEST8rr GR8:$src1, GR8:$src1)>;

    This relies on matching the result of TEST8rr (which is EFLAGS, which is
    an implicit def) to the result of X86cmp, an i32.

    infer results of a pattern from implicit defs.  This allows you to do something
    like this:

     def : Pat<(add ...),
               (FOOINST)>;

    When fooinst only has a single implicit def (e.g. to R1).  This will be handled
    as if written as (set R1, (FOOINST ...))

    Work around a valgrind oddity where it doesn't pass the full path of a
    script to the #! command by using bash instead of /bin/sh.  Bash
    searches $PATH for its script argument, but dash, which /bin/sh
    resolves to on some systems, does not.
    https://bugs.kde.org/show_bug.cgi?id=231257 tracks the valgrind

    Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() to
    always create a new jump table.  The intention was to avoid merging jump
    tables in SelectionDAGBuilder, and to wait for the branch folding pass to
    merge tables.  Unfortunately, the same getJumpTableIndex() method is also
    used to merge tables in branch folding, so as a result of this change
    branch tables are never merged.  Worse, the branch folding code is expecting
    getJumpTableIndex to always return the index of an existing table, but with
    this change, it never does so.  In at least some cases, e.g., pr6543, this
    creates references to non-existent tables.

    I've fixed the problem by adding a new createJumpTableIndex function, which
    will always create a new table, and I've changed getJumpTableIndex to only
    look at existing tables.

    Add the ability to "intern" FoldingSetNodeID data into a
    BumpPtrAllocator-allocated region to allow it to be stored in a more
    compact form and to avoid the need for a non-trivial destructor call.

    Use this new mechanism in ScalarEvolution instead of
    FastFoldingSetNode to avoid leaking memory in the case where a
    FoldingSetNodeID uses heap storage, and to reduce overall memory
    usage.

    Avoid a problem in libc_freeres() seen on a linux-i686 buildbot when running
    under valgrind:

    ==19577== Invalid free() / delete / delete[]
    ==19577==    at 0x4C9C866: free (vg_replace_malloc.c:325)
    ==19577==    by 0x5121104: ??? (in /lib/libc-2.10.2.so)
    ==19577==    by 0x4C97412: _vgnU_freeres (vg_preloaded.c:62)
    ==19577==    by 0x5041486: __run_exit_handlers (exit.c:93)
    ==19577==    by 0x50414FE: exit (exit.c:100)
    ==19577==    by 0x5028B5C: (below main) (libc-start.c:254)
    ==19577==  Address 0xffffffff is not stack'd, malloc'd or (recently) free'd
    ==19577==

    Apparently this happens under certain versions of glibc, so valgrind provides
    the --run-libc-freeres=no option to avoid calling freeres().  This may increase
    the number of "still reachable" blocks valgrind reports, but we don't care
    about those, while this error breaks the buildbots.

    There are upstream bugs about this at
    http://sourceware.org/bugzilla/show_bug.cgi?id=10610 and
    http://bugs.kde.org/show_bug.cgi?id=167483, but they don't look likely to be

    matches that of Firstcond[0] and E means otherwise.  The Firstcond[0] is also
    tagged in the Mask to facilitate Asm printing.  The disassembler also depends
    on this arrangement.  This is similar to what's described in A2.5.2 ITSTATE.

    Change SCEVNAryExpr's operand array from a SmallVector to a plain
    pointer and length, and allocate the arrays in ScalarEvolution's
    BumpPtrAllocator, so that they get released when their owning
    SCEV gets released. SCEVs are immutable, so they don't need to worry
    about operand array resizing. This fixes a memory leak reported
    in PR6637.

    Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm
    instructions to help disassembly.

    We also changed the output of the addressing modes to omit the '+' from the
    assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

    And modified test cases to not expect '+' in +reg or #+num.  For example,

    ; CHECK:       ldr.w	r9, [r7, #28]

    Fix EmitSectionOffset incorrect argument. DwarfDebug is emitting debug info so isEH is always false. This was hiding until now from compilers because of default arguments. This was hiding from dwarf debug info users because for most of the platform isAbsoluteEHSectionOffsets() is same as isAbsoluteDebugSectionOffsets(). But Chris found it while updating dwarf printer to use MC*.

    Fix a false-positive memory leak in code using RemoveFileOnSignal().  Because
    libstdc++'s std::string class points to the interior of an allocation, valgrind
    reports strings still alive at program termination as possible leaks.  I didn't
    use a ManagedStatic for this because System can't depend on Support.

    This is for the disassembly work.

    There are cases where this is not possible, for example, A8.6.53 LDM Encoding T1.

commit 5fe73e8bcefe45fb8a4fbaf37504538e3c212acc
Author: Johnny Chen <johnny.chen@apple.com>
Date:   Tue Mar 16 16:36:54 2010 +0000

    Initial ARM/Thumb disassembler check-in.  It consists of a tablgen backend
    (RISCDisassemblerEmitter) which emits the decoder functions for ARM and Thumb,
    and the disassembler core which invokes the decoder function and builds up the
    MCInst based on the decoded Opcode.

    Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm
    instructions to help disassembly.

    We also changed the output of the addressing modes to omit the '+' from the
    assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

    And modified test cases to not expect '+' in +reg or #+num.  For example,

    ; CHECK:       ldr.w	r9, [r7, #28]

    Stop using the old pre-UAL syntax for LDM/STM instruction suffixes.
    This does not move entirely to UAL syntax, since the default "increment after"
    suffix is empty but we still use "IA" for that.

    Fix the third (and last known) case of code update problems due
    to LLVM IR changes with addr label weirdness.  In the testcase, we
    generate references to the two bb's when codegen'ing the first
    function:

    _test1:                                 ## @test1
    	leaq	Ltmp0(%rip), %rax
    ..
    	leaq	Ltmp1(%rip), %rax

    Then continue to codegen the second function where the blocks
    get merged.  We're now smart enough to emit both labels, producing
    this code:

    _test_fun:                              ## @test_fun
    ## BB#0:                                ## %entry
    Ltmp1:                                  ## Block address taken
    Ltmp0:
    ## BB#1:                                ## %ret
    	movl	$-1, %eax
    	ret

    Rejoice.

    MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.
     - Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
     - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

    Place the LSDA into the TEXT section for x86 Darwin. If the global it's pointing
    to is local to the translation unit, we need to place fill the value of that
    symbol into the non-lazy pointer.

    This should conclude all Darwin changes for placing the LSDA into the TEXT
    section. There is some cleanup to do. I.e., there's no longer a special need for
    target-specific code here. But that can come later.

    fix a memory leak yjasskin pointed out: MCSymbol is bump pointer
    allocated and thus not freed.  This is cool except that it contains
    and std::string so the string data didn't get freed.  In any case
    there is no reason to redundantly store the string data in the
    MCSymbol anyway, just make the MCSymbol ref the string data in the
    MCContext StringMap.

commit d1bcd4082aea88582d15a0e2771bb7d19a7dd5cf
Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Mar 15 06:00:16 2010 +0000

    Completely rewrite tblgen's type inference mechanism,
    changing the primary datastructure from being a
    "std::vector<unsigned char>" to being a new TypeSet class
    that actually has (gasp) invariants!

    This changes more things than I remember, but one major
    innovation here is that it enforces that named input
    values agree in type with their output values.

    This also eliminates code that transparently assumes (in
    some cases) that SDNodeXForm input/output types are the
    same, because this is wrong in many case.

    This also eliminates a bug which caused a lot of ambiguous
    patterns to go undetected, where a register class would
    sometimes pick the first possible type, causing an
    ambiguous pattern to get arbitrary results.

    With all the recent target changes, this causes no
    functionality change!

    change EH related stuff (other than EH_LABEL) to use MCSymbol
    instead of label ID's.  This cleans up and regularizes a bunch
    of code and makes way for future progress.

    Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
    is largely copy and paste from DwarfException/MachineModuleInfo
    and other places.  This is very sad and disturbing. :(

    One major change here is that TidyLandingPads moved from being
    called in DwarfException::BeginFunction to being called in
    DwarfException::EndFunction.  There should not be any
    functionality change from doing this, but I'm not an EH expert.

    rearrange MCContext ownership.  Before LLVMTargetMachine created it
    and passing off ownership to AsmPrinter.  Now MachineModuleInfo
    creates it and owns it by value.  This allows us to use MCSymbols
    more consistently throughout the rest of the code generator, and
    simplifies a bit of code.  This also allows MachineFunction to
    keep an MCContext reference handy, and cleans up the TargetRegistry
    interfaces for AsmPrinters.

    Change ARM ld/st multiple instructions to have variant instructions for
    writebacks to the address register.  This gets rid of the hack that the
    first register on the list was the magic writeback register operand.  There
    was an implicit constraint that if that operand was not reg0 it had to match
    the base register operand.  The post-RA scheduler's antidependency breaker
    did not understand that constraint and sometimes changed one without the
    other.  This also fixes Radar 7495976 and should help the verifier work
    better for ARM code.

    There are now new ld/st instructions explicit writeback operands and explicit
    constraints that tie those registers together.

    MC/Mach-O: Implement initial support for relaxation.
     - The implementation is currently very brain dead and inefficient, but I have a
       clear plan on how to fix it.

     - The good news is, it works and correctly assembles 403.gcc (when built with
       Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
       the resulting binary is exactly equivalent to that when built with the system
       assembler. So it probably works! :)

    The same situation that effected ARM effects PPC with regards to placing the
    LSDA into the TEXT section. We need to generate non-lazy pointers to it on
    Mach-O. However, the object the NLP points to may be local to the translation
    unit. If so, then the NLP needs to have the value of that object specified
    instead of "0", which the linker interprets as "external".

    The check for coalescing a virtual register to a physical register, e.g.
    cl = EXTRACT_SUBREG reg1024, 1, is overly conservative. It should check
    for overlaps of vr's live interval with the super registers of the
    physical register (ECX in this case) and let JoinIntervals() handle checking
    the coalescing feasibility against the physical register (cl in this case).

    When outputing a non-lazy pointer for a stub, we may need to fill in the value
    for the NLP because the object it's pointing to may be internal to the file.

    This seems counter-intuitive, but bear with me. When we place the LSDA into the
    TEXT section, the type info pointers need to be indirect and pc-rel. We
    accomplish this by using NLPs. However, sometimes the types are local to the
    file. GCC gets around this by not using a NLP in this case, but a "regular"
    indirection like this:

    GCC_except_tbl:
      .long Lfoo-.

    __ZTIA:  @ This is local
      ...

    Lfoo:
      .long __ZTIA

    LLVM prefers NLPs on Darwin. In fact, it's more optimal for load performance to
    use them.

    Add a couple more heuristics to neuter machine cse some more.

    1. Be careful with cse "cheap" expressions. e.g. constant materialization. Only cse them when the common expression is local or in a direct predecessor. We don't want cse of cheap instruction causing other expressions to be spilled.
    2. Watch out for the case where the expression doesn't itself uses a virtual register. e.g. lea of frame object. If the common expression itself is used by copies (common for passing addresses to function calls), don't perform the cse. Since these expressions do not use a register, it creates a live range but doesn't close any, we want to be very careful with increasing register pressure.

    Note these are heuristics so machine cse doesn't make register allocator unhappy. Once we have proper live range splitting and re-materialization support in place, these should be evaluated again.

    Now machine cse is almost always a win on llvm nightly tests on x86 and x86_64.

    Try to keep the cached inliner costs around for a bit longer for big functions.

    The Caller cost info would be reset everytime a callee was inlined. If the
    caller has lots of calls and there is some mutual recursion going on, the
    caller cost info could be calculated many times.

    This patch reduces inliner runtime from 240s to 0.5s for a function with 20000
    small function calls.

    This is a more conservative version of r98089 that doesn't break the clang
    test CodeGenCXX/temp-order.cpp. That test relies on rather extreme inlining
    for constant folding.

    The ARM EH experiment worked!

    Place the LSDA into the TEXT section for ARM platforms. This involves making the
    encoding indirect, pcrel, and sdata4 instead of an absolute pointer. The
    references to the type infos are then non-lazy pointers. Revision 98019 changed
    the encoding of non-lazy pointers to add the symbol to the non-lazy pointer
    definition if it's a local symbol (otherwise, it's external and set to '0' so
    that the loader can adjust it to the real value). This paved the way for this
    change to work on ARM.

commit 1cbf3995c22e3d85143eda6e5ec99bcd367f5361
Author: Jakob Stoklund Olesen <stoklund@2pi.dk>
Date:   Tue Mar 9 00:59:48 2010 +0000

    Disable physical register coalescing when the number of live ranges for the
    physreg becomes ridiculously high.

    std::upper_bound may be log(N), but for sufficiently large live intervals, it
    becomes log(N)*cachemiss = a long long time.

    This patch improves coalescer time by 4500x for a function with 20000
    function calls. The generated code is different, but not significantly worse -
    the allocator hints are almost as good as physreg coalescing anyway.

    simplify EmitSectionOffset to always use .set if it is

    fix a bunch of partially ambiguous patterns on ARM.  As an
    example, this:

    (set DPR:$dst, (fsub (fneg (fmul DPR:$a, DPR:$b)), DPR:$dstin))

    is ambiguous because DPR contains both f64 and v2f32.  tblgen
    currently accidentally picks f64 because it's first in the
    regclass.

    teach tblgen to be more aggressive when factoring CheckType nodes.
    Now it will factor things like this:

    CheckType i32
      ...
    CheckOpcode ISD::AND
      CheckType i64
      ...

    into:

    SwitchType:
      i32: ...
      i64:
        CheckOpcode ISD::AND

    Better handling of dead super registers in LiveVariables. We used to do this:

       CALL ... %RAX<imp-def>
       ... [not using %RAX]
       %EAX = ..., %RAX<imp-use, kill>
       RET %EAX<imp-use,kill>

    Now we do this:

       CALL ... %RAX<imp-def, dead>
       ... [not using %RAX]
       %EAX = ...
       RET %EAX<imp-use,kill>

    By not artificially keeping %RAX alive, we lower register pressure a bit.

    The correct number of instructions for 2008-08-05-SpillerBug.ll is obviously
    55, anybody can see that. Sheesh.

    Reworking the stack layout that the MicroBlaze backend generates.

    The MicroBlaze backend was generating stack layouts that did not
    conform correctly to the ABI. This update generates stack layouts
    which are closer to what GCC does.

    Variable arguments support was added as well but the stack layout
    for varargs has not been finalized.

    parts of the cmp|cmp and cmp&cmp folding logic wasn't prepared for vectors
    (unrelated to the bug but noticed while in the code) and the code was
    *definitely* not safe to use by the (cast icmp)|(cast icmp) handling logic
    that I added in r95855.  Fix all this up by changing the various routines
    to more consistently use IRBuilder and not pass in the I which had the wrong
    type.

    Fix PR6497, a bug where we'd fold a load into an addc
    node which has a flag.  That flag in turn was used by an
    already-selected adde which turned into an ADC32ri8 which
    used a selected load which was chained to the load we
    folded.  This flag use caused us to form a cycle.  Fix
    this by not ignoring chains in IsLegalToFold even in
    cases where the isel thinks it can.

    Micro-optimization:

    This code:

    float floatingPointComparison(float x, float y) {
        double product = (double)x * y;
        if (product == 0.0)
            return product;
        return product - 1.0;
    }

    produces this:

    _floatingPointComparison:
    0000000000000000        cvtss2sd        %xmm1,%xmm1
    0000000000000004        cvtss2sd        %xmm0,%xmm0
    0000000000000008        mulsd           %xmm1,%xmm0
    000000000000000c        pxor            %xmm1,%xmm1
    0000000000000010        ucomisd         %xmm1,%xmm0
    0000000000000014        jne             0x00000004
    0000000000000016        jp              0x00000002
    0000000000000018        jmp             0x00000008
    000000000000001a        addsd           0x00000006(%rip),%xmm0
    0000000000000022        cvtsd2ss        %xmm0,%xmm0
    0000000000000026        ret

    The "jne/jp/jmp" sequence can be reduced to this instead:

    _floatingPointComparison:
    0000000000000000        cvtss2sd        %xmm1,%xmm1
    0000000000000004        cvtss2sd        %xmm0,%xmm0
    0000000000000008        mulsd           %xmm1,%xmm0
    000000000000000c        pxor            %xmm1,%xmm1
    0000000000000010        ucomisd         %xmm1,%xmm0
    0000000000000014        jp              0x00000002
    0000000000000016        je              0x00000008
    0000000000000018        addsd           0x00000006(%rip),%xmm0
    0000000000000020        cvtsd2ss        %xmm0,%xmm0
    0000000000000024        ret

    for a savings of 2 bytes.

    This xform can happen when we recognize that jne and jp jump to the same "true"
    MBB, the unconditional jump would jump to the "false" MBB, and the "true" branch
    is the fall-through MBB.

    just count references to it from JIT output to decide when to destroy it.  This

    to is destroyed.  External function stubs and GVIndirectSyms aren't destroyed
    until the JIT itself is.

    Added 32-bit Thumb instructions for Preload Data (PLD, PLDW) and Preload
    Instruction (PLI) for disassembly only.

    According to A8.6.120 PLI (immediate, literal), for example, different
    instructions are generated for "pli [pc, #0]" and "pli [pc, #-0"].  The
    disassembler solves it by mapping -0 (negative zero) to -1, -1 to -2, ..., etc.

    it is skipped.  A test with no unignored directives is resolved as Unsupported.

    The test suite is responsible for defining conditions;  conditions are unary
    functions over strings.  I've defined two conditions in the LLVM test suite,
    TARGET (with values like those in TARGETS_TO_BUILD) and BINDING (with values
    like those in llvm_bindings).  So for example you can write:
      IF(BINDING(ocaml)): RUN: %blah %s -o -
    and the RUN line will only execute if LLVM was configured with the ocaml
    bindings.

    Make the 'icmp pred trunc(ext(X)), CST --> icmp pred X, ext(trunc(CST))'
    transformation much more careful. Truncating binary '01' to '1' sounds like it's
    safe until you realize that it switched from positive to negative under a signed
    interpretation, and that depends on the icmp predicate.

    Also a few miscellaneous cleanups.

    now that  complexpatterns are all emitted at the end of the match

    change the new isel matcher to emit ComplexPattern matches
    as the very last thing before node emission.  This should
    dramatically reduce the number of times we do 'MatchAddress'
    on X86, speeding up compile time.  This also improves comments

    80506 bytes for x86.

This implements a special DenseMapInfo trait for DenseMap<MachineInstr*> that compare the value of the MachineInstr rather than the pointer value. Since the hashing and equality test functions ignore defs it's useful for doing CSE kind optimization.

    speed up scope node processing: if the first element of a scope
    entry we're about to process is obviously going to fail, don't
    bother pushing a scope only to have it immediately be popped.
    This avoids a lot of scope stack traffic in common cases.

    Unfortunately, this requires duplicating some of the predicate
    dispatch.  To avoid duplicating the actual logic I pulled each
    predicate out to its own static function which gets used in
    both places.

    factor the 'in the default address space' check out to a single

    factor the 'sign extended from 8 bit' patterns better so
    that they are not destination type specific.  This allows
    tblgen to factor them and the type check is redundant with
    what the isel does anyway.

Author: Evan Cheng <evan.cheng@apple.com>
Date:   Wed Mar 3 01:44:33 2010 +0000

    - Change MachineInstr::isIdenticalTo to take a new option that determines whether it should skip checking defs or at least virtual register defs. This subsumes part of the TargetInstrInfo::isIdentical functionality.
    - Eliminate TargetInstrInfo::isIdentical and replace it with produceSameValue. In the default case, produceSameValue just checks whether two machine instructions are identical (except for virtual register defs). But targets may override it to check for unusual cases (e.g. ARM pic loads from constant pools).

    This test case:

    long test(long x) { return (x & 123124) | 3; }

    Currently compiles to:

    _test:
            orl     $3, %edi
            movq    %rdi, %rax
            andq    $123127, %rax
            ret

    This is because instruction and DAG combiners canonicalize

      (or (and x, C), D) -> (and (or, D), (C | D))

    However, this is only profitable if (C & D) != 0. It gets in the way of the
    3-addressification because the input bits are known to be zero.

commit e15b5610729840a5a78cfcb623cb2ab530d06a40
Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Mar 2 22:20:06 2010 +0000

    Fix some issues in WalkChainUsers dealing with
    CopyToReg/CopyFromReg/INLINEASM.  These are annoying because
    they have the same opcode before an after isel.  Fix this by
    setting their NodeID to -1 to indicate that they are selected,
    just like what automatically happens when selecting things that
    end up being machine nodes.

    With that done, give IsLegalToFold a new flag that causes it to
    ignore chains.  This lets the HandleMergeInputChains routine be
    the one place that validates chains after a match is successful,
    enabling the new hotness in chain processing.  This smarter
    chain processing eliminates the need for "PreprocessRMW" in the
    X86 and MSP430 backends and enables MSP to start matching it's
    multiple mem operand instructions more aggressively.

    I currently #if out the dead code in the X86 backend and MSP
    backend, I'll remove it for real in a follow-on patch.

    The testcase changes are:
      test/CodeGen/X86/sse3.ll: we generate better code
      test/CodeGen/X86/store_op_load_fold2.ll: PreprocessRMW was
          miscompiling this before, we now generate correct code
          Convert it to filecheck while I'm at it.
      test/CodeGen/MSP430/Inst16mm.ll: Add a testcase for mem/mem
          folding to make anton happy. :)

    Fix the xfail I added a couple of patches back.  The issue
    was that we weren't properly handling the case when interior
    nodes of a matched pattern become dead after updating chain
    and flag uses.  Now we handle this explicitly in
    UpdateChainsAndFlags.

commit 645d1cecf03833d5fdcd62a62286d3193d6dda20
Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Mar 2 02:22:10 2010 +0000

    Rewrite chain handling validation and input TokenFactor handling
    stuff now that we don't care about emulating the old broken
    behavior of the old isel.  This eliminates the
    'CheckChainCompatible' check (along with IsChainCompatible) which
    did an incorrect and inefficient scan *up* the chain nodes which
    happened as the pattern was being formed and does the validation
    at the end in HandleMergeInputChains when it forms a structural
    pattern.  This scans "down" the graph, which means that it is
    quickly bounded by nodes already selected.  This also handles
    token factors that get "trapped" in the dag.

    Removing the CheckChainCompatible nodes also shrinks the
    generated tables by about 6K for X86 (down to 83K).

    There are two pieces remaining before I can nuke PreprocessRMW:
    1. I xfailed a test because we're now producing worse code in a
       case that has nothing to do with the change: it turns out that
       our use of MorphNodeTo will leave dead nodes in the graph
       which (depending on how the graph is walked) end up causing
       bogus uses of chains and blocking matches.  This is really
       bad for other reasons, so I'll fix this in a follow-up patch.

    2. CheckFoldableChainNode needs to be improved to handle the TF.

    We force this by using the record ID order as a fallback.

    The testsuite diff is due to alpha patterns being ordered
    slightly differently, the change is a semantic noop afaict:

    Remove the optimize for code size limitation on r67917. Optimize 64-bit imul by constants into leas + shl regardless if optimizing for code size. The size saving from using imulq isn't worth it. Also, the lea and shl instructions may expose further optimization.

    Emit type checks late instead of early, this encourages
    structural matching code to be factored and shared this
    shrinks the X86 isel table from 86537 to 83890 bytes.

Date:   Mon Mar 1 07:27:07 2010 +0000

    Emit a redundant check for immediates at root context, e.g. (imm 0).
    This allows formation of OpcodeSwitch for top level patterns, in
    particular on X86.  This saves about 1K of data space in the x86
    table and makes the dispatch much more efficient.

Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Mar 1 07:17:40 2010 +0000

    eliminate the CheckMultiOpcodeMatcher code and have each
    ComplexPattern at the root be generated multiple times, once
    for each opcode they are part of.  This encourages factoring
    because the opcode checks get treated just like everything
    else in the matcher.

Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Mar 1 06:59:22 2010 +0000

    add a new OPC_SwitchOpcode which is semantically equivalent
    to a scope where every child starts with a CheckOpcode, but
    executes more efficiently.  Enhance DAGISelMatcherOpt to
    form it.

    This also fixes a bug in CheckOpcode: apparently the SDNodeInfo
    objects are not pointer comparable, we have to compare the
    enum name.

    pull MarkFlagResult out from between an EmitNode/CompleteMatch
    pair.  This encourages MorphNodeTo formation, this gets us 200
    more MorphNodeTo's on X86 and shrinks the table a bit.

Date:   Mon Mar 1 02:15:34 2010 +0000

    Emit redundant opcode checks for andimm and orimm tests at root
    so that we get grouping at the top level.

    Add an optimization to reorder type check & record nodes
    after opcode checks.  We prefer to expose tree shape
    matching which improves grouping and will enhance the next
    optimization.

    inline the node transforms and node predicates into the generated

    Teach APFloat how to create both QNaNs and SNaNs and with arbitrary-width
    payloads.  APFloat's internal folding routines always make QNaNs now,
    instead of sometimes making QNaNs and sometimes SNaNs depending on the
    type.

    Generalize my hack to use SDNodeInfo to find out when a
    node is always guaranteed to have a particular type
    instead of hacking in ISD::STORE explicitly.  This allows
    us to use implied types for a broad range of nodes, even
    target specific ones.

    Implement XMM subregs.

    Extracting the low element of a vector is now done with EXTRACT_SUBREG,
    and the zero-extension performed by load movss is now modeled with
    SUBREG_TO_REG, and so on.

    Register-to-register movss and movsd are no longer considered copies;
    they are two-address instructions which insert a scalar into a vector.

    Don't unconditionally suppress hoisting of instructions with implicit

    remove a bogus pattern, which had the same pattern as STDU
    but codegen'd differently.  This really wanted to use some
    sort of subreg to get the low 4 bytes of the G8RC register

    it, so I'm just zapping the bogosity.

    Teach the grouper some simple tricks about looking contradictory
    predicates.  For example if we have:

    Scope:
      CheckType i32
        ABC
      CheckType f32
        DEF
      CheckType i32
        GHI

    Then we know that we can transform this into:
    Scope:
      CheckType i32
        Scope
          ABC
          GHI
      CheckType f32
        DEF

    This reorders the check for the 'GHI' predicate above
    the check for the 'DEF' predidate.  However it is safe to do this
    in this situation because we know that a node cannot have both an
    i32 and f32 type.

    We're now doing more factoring that the old isel did.

    as deeply into the pattern as we can get away with.  In pratice, this
    means "all the way to to the emitter code, but not across

    we get.

    Use the right floating point load/store instructions in PPCInstrInfo::foldMemoryOperandImpl().

    The PowerPC floating point registers can represent both f32 and f64 via the
    two register classes F4RC and F8RC. F8RC is considered a subclass of F4RC to
    allow cross-class coalescing. This coalescing only affects whether registers
    are spilled as f32 or f64.

    Spill slots must be accessed with load/store instructions corresponding to the
    class of the spilled register. PPCInstrInfo::foldMemoryOperandImpl was looking
    at the instruction opcode which is wrong.

    X86 has similar floating point register classes, but doesn't try to fold
    memory operands, so there is no problem there.

    finish off the factoring optimization along the lines of the
    current design.  This generates a matcher that successfully
    runs, but it turns out that the factoring we're doing violates
    the ordering of patterns, so we end up matching (e.g.) movups
    where we want movaps.  This won't due, but I'll address this in
    a follow on patch.  It's nice to not be on by default yet! :)

    Catch a corner case where adding the padding to the "TType base offset" field
    will eliminate the need for padding in the "Call site table length". E.g., if
    we have this:

        GCC_except_table1:
        Lexception1:
            .byte   0xff  ## @LPStart Encoding = omit
            .byte   0x9b  ## @TType Encoding = indirect pcrel sdata4
            .byte   0x7f  ## @TType base offset

        GCC_except_table1:
        Lexception1:
            .byte   0xff  ## @LPStart Encoding = omit
            .byte   0x9b  ## @TType Encoding = indirect pcrel sdata4
            .byte   0xff  ## @TType base offset
            .space  1,0   ## Padding
            .byte   0x03  ## Call site Encoding = udata4
            .byte   0x89  ## Call site table length

    and not with padding on the "Call site table length" entry.

    Make the side-numbering of instructions used by metadata (which is needed to
    keep track of instructions that return void) per-function. This fixes PR5278.

    Implement the first half of redundancy factoring: efficiently
    splitting all the patterns under scope nodes into equality sets
    based on their first node.  The second step is to rewrite the

    I want to redesign the Scope node.

    Large stack frame patch for the CellSPU: handle stack frames that exceed 8176
    (511*16) bytes register displacement (D-form).

    NOTE: This is a potential headache, given the SPU's local core limitations,
    allowing the software developer to commit stack overrun suicide unknowingly.
    Also, large SPU stack frames will cause code size explosion. But, one presumes
    that the software developer knows what they're doing...

    LLVM puts padding bytes in the __gcc_except_tab section after the
    GCC_except_table label but before the Lexception, which the FDE references.
    This causes problems as the FDE does not point to the start of an LSDA chunk.

    Use an unnormalized uleb128 for the call-site table length that includes the
    padding.

    Create a stack frame on ARM when

    - Function uses all scratch registers AND
    - Function does not use any callee saved registers AND
    - Stack size is too big to address with immediate offsets.

    In this case a register must be scavenged to calculate the address of a stack
    object, and the scavenger needs a spare register or emergency spill slot.

    When forming SSE min and max nodes for UGE and ULE comparisons, it's
    necessary to swap the operands to handle NaN and negative zero properly.

    Also, reintroduce logic for checking for NaN conditions when forming
    SSE min and max instructions, fixed to take into consideration NaNs and
    negative zeros. This allows forming min and max instructions in more
    cases.

    Change the scheduler from adding nodes in allnodes order
    to adding them in a determinstic order (bottom up from
    the root) based on the structure of the graph itself.

    This updates tests for some random changes, interesting
    bits: CodeGen/Blackfin/promote-logic.ll no longer crashes.
    I have no idea why, but that's good right?

    CodeGen/X86/2009-07-16-LoadFoldingBug.ll also fails, but
    now compiles to have one fewer constant pool entry, making
    the expected load that was being folded disappear.  Since it
    is an unreduced mass of gnast, I just removed it.

    The new isel was not properly handling patterns that covered
    internal nodes with flag results.  Record these with a new
    OPC_MarkFlagResults opcode and use this to update the interior
    nodes' flag results properly.  This fixes CodeGen/X86/i256-add.ll
    with the new isel.

Author: Bob Wilson <bob.wilson@apple.com>

    Add an argument to PHITranslateValue to specify the DominatorTree.  If this
    argument is non-null, pass it along to PHITranslateSubExpr so that it can
    prefer using existing values that dominate the PredBB, instead of just
    blindly picking the first equivalent value that it finds on a uselist.
    Also when the DominatorTree is specified, have PHITranslateValue filter
    out any result that does not dominate the PredBB.  This is basically just
    refactoring the check that used to be in GetAvailablePHITranslatedSubExpr
    and also in GVN.

    Despite my initial expectations, this change does not affect the results
    of GVN for any testcases that I could find, but it should help compile time.
    Before this change, if PHITranslateSubExpr picked a value that does not
    dominate, PHITranslateWithInsertion would then insert a new value, which GVN
    would later determine to be redundant and would replace.  By picking a good
    value to begin with, we save GVN the extra work of inserting and then
    replacing a new value.

    This is the second patch to allow x86 code to be aligned with optimal nops.
    With the compiler changed to use EmitCodeAlignment() it does change the
    functionality.  But X86 assembly code assembled with llvm-mc does not change
    its output.  For that we will eventually change the assembler frontend to
    detect a '.align x, 0x90' when used in a section that 'hasInstructions' and use
    EmitCodeAlignment, but will wait until we have better target hooks.

    http://www.xilinx.com/tools/microblaze.htm
    http://en.wikipedia.org/wiki/MicroBlaze

    The current LLVM MicroBlaze backend generates assembly which can be
    compiled using the an appropriate binutils assembler.

    and when the compiler is changed to use EmitCodeAlignment() it should also not
    change the resulting output.  Once the compiler change is made and everything
    looks good the next patch with the table of optimal X86 nops will be added to
    WriteNopData() changing the output.  There are many FIXMEs in this patch which
    will be removed when we have better target hooks (coming soon I hear).

    Remove the code which constant-folded ptrtoint(inttoptr(x)+c) to
    getelementptr. Despite only doing so in the case where x is a known
    array object and c can be converted to an index within range, this
    could still be invalid if c is actually the address of an object
    allocated outside of LLVM. Also, SCEVExpander, the original motivation
    for this code, has since been improved to avoid inttoptr+ptroint in
    more cases.

Author: Daniel Dunbar <daniel@zuster.org>
Date:   Tue Feb 23 10:00:49 2010 +0000

    Initial configure support for using Clang as the LLVM capable compiler.

    Comes in two parts:
     1. Use --with-clang=path/to/clang/compiler to select an installed clang, or
        --with-built-clang to have the makefiles use the clang which will be built
        as the LLVM capable compiler. If neither is given, --with-built-clang will
        be used if the Clang sources are checked out into the standard location
        (tools/clang).

     2. Use --with-llvmcc={llvm-gcc,clang,none} to specify which LLVM capable
        compiler to use. If not given, then llvm-gcc will be used if available,
        otherwise Clang.

    Makefile support still to come.

    Eric, Doug, Chris, seem reasonable?

    Implement order-preserving option forwarding.

    Needed to correctly handle things like 'llvmc -framework Foo foo.o -framework
    Bar bar.o' - before this commit all '-framework' options would've been grouped
    together in the beginning.

    Due to our dependence on CommandLine this turned out to be a giant hack; we will
    migrate away from CommandLine eventually.

    Change ComplexPattern handling to push the node being matched as

    allows CheckSame to work correctly when matching replicated

    due to a sched bug.

    The test difference is just due to the multiplication operands
    being commuted (and thus requiring a more elaborate match). In

    Mark the return address stack slot as mutable when moving the return address
    during a tail call. A parameter might overwrite this stack slot during the tail
    call.

    The sequence during a tail call is:
    1.) load return address to temp reg
    2.) move parameters (might involve storing to return address stack slot)
    3.) store return address to new location from temp reg

    If the stack location is marked immutable CodeGen can colocate load (1) with the
    store (3).

    This fixes bug 6225.

    Remove the logic for reasoning about NaNs from the code that forms
    SSE min and max instructions. The real thing this code needs to be
    concerned about is negative zero.

    Update the sse-minmax.ll test accordingly, and add tests for
    -enable-unsafe-fp-math mode as well.

Author: Dan Gohman <gohman@apple.com>
Date:   Mon Feb 22 03:59:54 2010 +0000

    When emitting an instruction which depends on both a post-incremented
    induction variable value and a loop-variant value, don't force the
    insert position to be at the post-increment position, because it may
    not be dominated by the loop-variant value. This fixes a
    use-before-def problem noticed on PPC.

    fix most of the failures in the x86 suite by handling multiple
    result nodes correctly.  Note that this includes a horrible hack
    in DAGISelHeader which cannot be fixed reasonably without
    eliminating (parallel) from input patterns.  That, in turn,
    can't be done until we support writing multiple result patterns
    for the X86and_flag and related multiple-result nodes.

    It turned out that we failed to emit proper symbol stubs on non-x86/darwin for ages (we emitted a reference to a stub, but no stub was emitted). The code inside x86-32/macho target objfile lowering should actually be the generic one - move it there.

    This (I really, really hope) should fix EH issues on ppc/darwin
    and arm/darwin.

    Lots of improvements to the new dagisel emitter.  This gets it to
    the point where it is to the 95% feature complete mark, it just
    needs result updating to be done (then testing, optimization
    etc).

    More specificallly, this adds support for chain and flag handling
    on the result nodes, support for sdnodexforms, support for variadic
    nodes, memrefs, pinned physreg inputs, and probably lots of other
    stuff.

    In the old DAGISelEmitter, this deletes the dead code related to
    OperatorMap, cleans up a variety of dead stuff handling "implicit
    remapping" from things like globaladdr -> targetglobaladdr (which
    is no longer used because globaladdr always needs to be legalized),
    and some minor formatting fixes.

    rename SelectScalarSSELoad -> SelectScalarSSELoadXXX and rewrite
    it to follow the mode needed by the new isel.  Instead of returning
    the input and output chains, it just returns the (currently only one,
    which is a silly limitation) node that has input and output chains.

    Since we want the old thing to still work, add a new
    SelectScalarSSELoad to emulate the old interface.  The XXX suffix
    and the wrapper will eventually go away.

    Revert commits 96556 and 96640, because commit 96556 breaks the
    dragonegg self-host build.  I reverted 96640 in order to revert
    96556 (96640 goes on top of 96556), but it also looks like with
    both of them applied the breakage happens even earlier.  The
    symptom of the 96556 miscompile is the following crash:

      llvm[3]: Compiling AlphaISelLowering.cpp for Release build
      cc1plus: /home/duncan/tmp/tmp/llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:4982: void llvm::SelectionDAG::ReplaceAllUsesWith(llvm::SDNode*, llvm::SDNode*, llvm::SelectionDAG::DAGUpdateListener*): Assertion `(!From->hasAnyUseOfValue(i) || From->getValueType(i) == To->getValueType(i)) && "Cannot use this version of ReplaceAllUsesWith!"' failed.
      Stack dump:

      g++: Internal error: Aborted (program cc1plus)

    This occurs when building LLVM using LLVM built by LLVM (via
    dragonegg).  Probably LLVM has miscompiled itself, though it
    may have miscompiled GCC and/or dragonegg itself: at this point
    of the self-host build, all of GCC, LLVM and dragonegg were built
    using LLVM.  Unfortunately this kind of thing is extremely hard
    to debug, and while I did rummage around a bit I didn't find any
    smoking guns, aka obviously miscompiled code.

    Found by bisection.

    Radar 7636153. In the presence of large call frames, it's not sufficient
    for ARM to just check if a function has a FP to determine if it's safe
    to simplify the stack adjustment pseudo ops prior to eliminating frame
    indices. Allow targets to override the default behavior and does so for ARM
    and Thumb2.

    Always normalize spill weights, also for intervals created by spilling.

    Moderate the weight given to very small intervals.

    The spill weight given to new intervals created when spilling was not
    normalized in the same way as the original spill weights calculated by
    CalcSpillWeights. That meant that restored registers would tend to hang around
    because they had a much higher spill weight that unspilled registers.

    This improves the runtime of a few tests by up to 10%, and there are no
    significant regressions.

Author: Jeffrey Yasskin <jyasskin@google.com>

    Add a shared library for LLVM, named libLLVM2.7svn.(so|dylib), and add an
    --enable-shared configure flag to have the tools linked shared. (2.7svn is just
    $(LLVMVersion) so it'll change to "2.7" in the release.)  Always link the
    example programs shared to test that the shared library keeps working.

    On my mac laptop, Debug libLLVM2.7svn.dylib is 39MB, and opt (for example) is
    16M static vs 440K shared.

    Two things are less than ideal here:
    1) The library doesn't include any version information. Since we expect to break
    the ABI with every release, this shouldn't be much of a problem. If we do
    release a compatible 2.7.1, we may be able to hack its library to work with
    binaries compiled against 2.7.0, or we can just ask them to recompile. I'm
    hoping to get a real packaging expert to look at this for the 2.8 release.
    2) llvm-config doesn't yet have an option to print link options for the shared
    library. I'll add this as a subsequent patch.

    More cleanup for NEON:
    * Use "S" abbreviation for scalar single FP registers in class and pattern
    names, instead of keeping the "D" (for "double") abbreviation and tacking on
    an "s" elsewhere in the name.
    * Move the scalar single FP register classes and patterns to be more
    consistent with other definitions in the file.
    * Rename "VNEGf32d" definition to "VNEGfd" for consistency.
    * Deleted the N2VDIntsPat pattern; N2VSPat is good enough.

    Initial implementation of PIC16 Cloner pass.

    This pass is supposed to be run on the linked .bc module.
    It traveses the module call graph twice. Once starting from the main function
    and marking each reached function as "ML". Again, starting from the ISR
    and cloning any reachable function that was marked as "ML". After cloning
    the function, it remaps all the call sites in IL functions to call the
    cloned functions.

    Currently only marking is being done.

    fix rdar://7653908, a crash on a case where we would fold a load
    into a roundss intrinsic, producing a cyclic dag.  The root cause
    of this is badness handling ComplexPattern nodes in the old dagisel
    that I noticed through inspection.  Eliminate a copy of the of the
    code that handled ComplexPatterns by making EmitChildMatchCode call
    into EmitMatchCode.

    Look for SSE and instructions of this form: (and x, (build_vector c1,c2,c3,c4)).
    If there exists a use of a build_vector that's the bitwise complement of the mask,
    then transform the node to
    (and (xor x, (build_vector -1,-1,-1,-1)), (build_vector ~c1,~c2,~c3,~c4)).

    Since this transformation is only useful when 1) the given build_vector will
    become a load from constpool, and 2) (and (xor x -1), y) matches to a single
    instruction, I decided this is appropriate as a x86 specific transformation.

    First step in eliminating the CarryDefIsUnused and CarryDefIsUsed predicates.
    They won't work with the new ISel mechanism, as Requires predicates are no
    longer allowed to reference the node being selected. Moving the predicate to
    the patterns instead solves the problem.

    This patch handles ARM mode. Thumb2 will follow.

    convert the new matcher to check intermediate nodes for a single

    sharing.

    change dag isel emitter to only call 'IsProfitableToFold' on nodes
    with chains.  On interior nodes that lead up to them, we just directly
    check that there is a single use.  This generates slightly more
    efficient code.

    llvm-gcc but has been replaced with pad argument which don't need any
    special backend support.

    Split the main for-each-use loop again, this time for GenerateTruncates,
    as it also peeks at which registers are being used by other uses. This
    makes LSR less sensitive to use-list order.

    It turns out that we emitted completely wrong common EH frame since the early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong.

    Split SelectionDAGISel::IsLegalAndProfitableToFold to
    IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

    This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

    Check in the first big step of rewriting DAGISelEmitter to
    produce a table based matcher instead of gobs of C++ Code.

    Though it's not done yet, the shrinkage seems promising,
    the table for the X86 ISel is 75K and still has a lot of
    optimization to come (compare to the ~1.5M of .o generated
    the old way, much of which will go away).

    The code is currently disabled by default (the #if 0 in
    DAGISelEmitter.cpp).  When enabled it generates a dead
    SelectCode2 function in the DAGISel Header which will
    eventually replace SelectCode.

    There is still a lot of stuff left to do, which are
    documented with a trail of FIXMEs.

    When complicated expressions are broken down into subexpressions
    with multiplication by constants distributed through, occasionally
    those subexpressions can include both x and -x. For now, if this
    condition is discovered within LSR, just prune such cases away,
    as they won't be profitable. This fixes a "zero allocated in a
    base register" assertion failure.

    Fix PR6283.

    When coalescing with a physreg, remember to add imp-def and imp-kill when
    dealing with sub-registers.

    Also fix a related bug in VirtRegRewriter where substitutePhysReg may
    reallocate the operand list on an instruction and invalidate the reg_iterator.
    This can happen when a register is mentioned twice on the same instruction.

    Teach MachineFrameInfo to track maximum alignment while stack objects are being

    dynamic stack alignment would know whether it is required and whether frame

    Enable the inlinehint attribute in the Inliner.

    Functions explicitly marked inline will get an inlining threshold slightly
    more aggressive than the default for -O3. This means than -O3 builds are
    mostly unaffected while -Os builds will be a bit bigger and faster.

    The difference depends entirely on how many 'inline's are sprinkled on the
    source.

    In the CINT2006 suite, only these tests are significantly affected under -Os:

                   Size   Time
    471.omnetpp   +1.63% -1.85%
    473.astar     +4.01% -6.02%
    483.xalancbmk +4.60%  0.00%

    Note that 483.xalancbmk runs too quickly to give useful timing results.

    Reworked the Intel disassembler to support instructions
    whose opcodes extend into the ModR/M field using the
    Form field of the instruction rather than by special
    casing each instruction.  Commented out the special
    casing of VMCALL, which is the first instruction to use
    this special form.  While I was in the neighborhood,
    added a few comments for people modifying the Intel
    disassembler.

    implement infrastructure to support fixups for rip-rel
    addressing.  This isn't complete because I need an MCContext
    to generate new MCExprs.

    When save/restoring CR at prolog/epilog, in a large
    stack frame, the prolog/epilog code was using the same
    register for the copy of CR and the address of the save slot.  Oops.
    This is fixed here for Darwin, sort of, by reserving R2 for this case.
    A better way would be to do the store before the decrement of SP,
    which is safe on Darwin due to the red zone.

    SVR4 probably has the same problem, but I don't know how to fix it;
    there is no red zone and R2 is already used for something else.
    I'm going to leave it to someone interested in that target.

    Better still would be to rewrite the CR-saving code completely;
    spilling each CR subregister individually is horrible code.

    Add a new pass on machine instructions to optimize away PHI cycles that
    reduce down to a single value.  InstCombine already does this transformation
    but DAG legalization may introduce new opportunities.  This has turned out to
    be important for ARM where 64-bit values are split up during type legalization:
    InstCombine is not able to remove the PHI cycles on the 64-bit values but
    the separate 32-bit values can be optimized.  I measured the compile time
    impact of this (running llc on 176.gcc) and it was not significant.

    Add and commonize encoder support for all immediates.
    Stub out some dummy fixups to make things work.

    We can now emit fixups like this:
    	subl	$20, %esp               ## encoding: [0x83,0xec,A]
                                            ##   fixup A - offset: 2, value: 20, kind: fixup_1byte_imm

    Emitting $20 as a single-byte fixup to be later resolved
    by the assembler is ridiculous of course (vs just emitting
    the byte) but this is a failure of the matcher, which
    should be producing an imm of 20, not an MCExpr of 20.

    Rename ValueRequiresCast to ShouldOptimizeCast, to better reflect
    what it does.  Enhance it to return false to optimizing vector
    sign extensions from vector comparisions, which is the idiom used
    to get a splatted vector for a vector comparison.

    Doing this breaks vector-casts.ll, add some compensating
    transformations to handle the important case they cover without
    depending on this canonicalization.

    This fixes rdar://7434900 a serious pessimization of vector compares.

    The previous fix of widening divides that trap was too fragile as it depends on custom
    lowering and requires that certain types exist in ValueTypes.h.  Modified widening to
    check if an op can trap and if so, the widening algorithm will apply only the op on
    the defined elements.  It is safer to do this in widening because the optimizer can't
    guarantee removing unused ops in some cases.

Author: Garrison Venn <gvenn.cfe.dev@gmail.com>
Date:   Tue Feb 9 23:22:43 2010 +0000

    Adds a JIT based exception handling example to the examples directory.
    Both zero cost example domain specific, and C++ foreign exception handling are
    shown. The example's documentation fully explains how to run the example.

    Notes:

    1)   The code uses an extremely simple type info model.
    2)   Only a single landing pad is used per unwind edge
         (one call to llvm.eh.selector)
    3)   llvm.eh.selector support for filter arguments is not given.
    4)   llvm.eh.typeid.for is not used.
    5)   Forced unwind behavior is not supported.
    6)   Very little if any error handling is given.
    7)   __attribute__((__aligned__)) is used.
    8)   The code uses parts from the llvm compiler-rt project and
         the llvm Kaleidoscope example.
    9)   The code has not been ported or tested on WINDOWS.
    10)  The code was not tested with a cmake build.
    11)  The code was tested for a debug build on 32bit X86 CentOS LINUX,
         and both a debug and release build on OS X 10.6.2 (64bit).

    Per PR 6219, factored AsmWriterInst and AsmWriterOperand
    out of the AsmWriterEmitter.  This patch does the physical

    Radar 7417921

    tMOVCCi pattern only valid for low registers, as the Thumb1 mov immediate to
    register instruction only works with low registers. Allowing high registers
    for the instruction resulted in the assembler choosing the wide (32-bit)
    encoding for the mov, but LLVM though the instruction was only 16 bits wide,
    so offset calculations for constant pools became incorrect, leading to
    out of range constant pool entries.

commit 73aae2a863dc7bdc27506b9d9f8c037cb35bc810
Author: Lang Hames <lhames@gmail.com>
Date:   Tue Feb 9 00:50:27 2010 +0000

    Fixed a bug in the PBQP allocator's findCoalesces method.

    Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with.

    Give DwarfPrinter a protected (but not virtual) destructor.  Cppcheck
    warns about this base class not having a virtual destructor, but since
    this class has no virtual methods and neither it or the types derived
    from it has a destructor, a protected trivial destructor will do (and
    shuts cppcheck up) the trick without the cost of introducing a vtable.

    if its type (but respect the alignment).
    - Store all variable arguments back to the caller stack.

    Run codegen dce pass for all targets at all optimization levels. Previously it's
    only run for x86 with fastisel. I've found it being very effective in
    eliminating some obvious dead code as result of formal parameter lowering
    especially when tail call optimization eliminated the need for some of the loads
    from fixed frame objects. It also shrinks a number of the tests. A couple of
    tests no longer make sense and are now eliminated.

    Reintroduce the InlineHint function attribute.

    This time it's for real! I am going to hook this up in the frontends as well.

    The inliner has some experimental heuristics for dealing with the inline hint.
    When given a -respect-inlinehint option, functions marked with the inline
    keyword are given a threshold just above the default for -O3.

    We need some experiments to determine if that is the right thing to do.

    Teach SimplifyCFG about magic pointer constants.

    Weird code sometimes uses pointer constants other than null. This patch
    teaches SimplifyCFG to build switch instructions in those cases.

    Code like this:

    void f(const char *x) {
      if (!x)
        puts("null");
      else if ((uintptr_t)x == 1)
        puts("one");
      else if (x == (char*)2 || x == (char*)3)
        puts("two");
      else if ((intptr_t)x == 4)
        puts("four");
      else
        puts(x);
    }

    Now becomes a switch:

    define void @f(i8* %x) nounwind ssp {
    entry:
      %magicptr23 = ptrtoint i8* %x to i64            ; <i64> [#uses=1]
      switch i64 %magicptr23, label %if.else16 [
        i64 0, label %if.then
        i64 1, label %if.then2
        i64 2, label %if.then9
        i64 3, label %if.then9
        i64 4, label %if.then14
      ]

    Note that LLVM's own DenseMap uses magic pointers.

    When the scheduler unfold a load folding instruction it move some of the predecessors to the unfolded load. It decides what gets moved to the load by checking whether the new load is using the predecessor as an operand. The check neglects the cases whether the predecessor is a flagged scheduling unit.

    An empty global constant (one of size 0) may have a section immediately
    following it. However, the EmitGlobalConstant method wasn't emitting a body for
    the constant. The assembler doesn't like that. Before, we were generating this:

      .zerofill __DATA, __common, __cmd, 1, 3

    This fix puts us back to that semantic.

    Do not reassociate expressions with i1 type.  SimplifyCFG converts some
    short-circuited conditions to AND/OR expressions, and those expressions
    are often converted back to a short-circuited form in code gen.  The
    original source order may have been optimized to take advantage of the
    expected values, and if we reassociate them, we change the order and
    subvert that optimization.  Radar 7497329.

    Indirect tail call has to go through a call preserved register since it's after callee register pops. X86 isel lowering is using EAX / R11 and it was somehow adding that to function live out. That prevented the real function return register from being added to the function live out list and bad things happen.
    This fixes 483.xalancbmk (with tail call opt).

    Added support for X86 instruction prefixes so llvm-mc can assemble them.  The
    Lock prefix, Repeat string operation prefixes and the Segment override prefixes.
    Also added versions of the move string and store string instructions without the
    repeat prefixes to X86InstrInfo.td. And finally marked the rep versions of
    move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is
    happy building the disassembler files.

commit 66b7149074808f51fd6365b509028ff862a05108
Author: Bob Wilson <bob.wilson@apple.com>
Date:   Wed Feb 3 17:23:56 2010 +0000

    Adjust the heuristics used to decide when SROA is likely to be profitable.
    The SRThreshold value makes perfect sense for checking if an entire aggregate
    should be promoted to a scalar integer, but it is not so good for splitting
    an aggregate into its separate elements.  A struct may contain a large embedded
    array along with some scalar fields that would benefit from being split apart
    by SROA.  Even if the total aggregate size is large, it may still be good to
    perform SROA.  Thus, the most important piece of this patch is simply moving
    the aggregate size comparison vs. SRThreshold so that it guards only the
    aggregate promotion.

    We have also been checking the number of elements to decide if an aggregate
    should be split up.  The limit of "SRThreshold/4" seemed rather arbitrary,
    and I don't think it's very useful to derive this limit from SRThreshold
    anyway.  I've collected some data showing that the current default limit of
    32 (since SRThreshold defaults to 128) is a reasonable cutoff for struct
    types.  One thing suggested by the data is that distinguishing between structs
    and arrays might be useful.  There are (obviously) a lot more large arrays
    than large structs (as measured by the number of elements and not the total
    size -- a large array inside a struct still counts as a single element given
    the way we do SROA right now).  Out of 8377 arrays where we successfully
    performed SROA while compiling a large set of benchmarks, only 16 of them had
    more than 8 elements.  And, for those 16 arrays, it's not at all clear that
    SROA was actually beneficial.  So, to offset the compile time cost of
    investigating more large structs for SROA, the patch lowers the limit on array
    elements to 8.

    This fixes Apple Radar 7563690.

    make any use of the "O" stream in asmprinter print to
    stderr if in filetype=obj mode.  This is a hack, and will
    live until dwarf emission and other random stuff that is
    not yet going through MCStreamer is upgraded.  It only
    impacts filetype=obj mode.

    eliminate all forms of addPassesToEmitMachineCode except
    the one used by the JIT.  Remove all forms of
    addPassesToEmitFileFinish except the one used by the static
    code generator.  Inline the remaining version of
    addPassesToEmitFileFinish into its only caller.

    Added another version of the X86 assembler matcher test case.
    This test case is different subset of the full auto generated test case, and a
    larger subset that is in x86_32-bit.s (that set will encode correctly).  These
    instructions can pass though llvm-mc as it were a logical cat(1) and then
    reassemble to the same instruction.  It is useful as we bring up the parser and
    matcher so we don't break things that currently work.

    int bar(int a, int b, int c) {
      return foo(a, b, c);

    Changed to Chris Lattner's suggested approach, which
    merely stubs out the blocks-based disassembly functions
    if the library wasn't built with blocks, which allows a
    constant .exports file and also properly deals with
    situations in which the compiler used to build a client
    is different from the compiler used to build the library.

    where it is unavailable, and then if it is safe, the code is changed to move
    the load.  Radar 7571861.

    Generalize target-independent folding rules for sizeof to handle more
    cases, and implement target-independent folding rules for alignof and
    offsetof. Also, reassociate reassociative operators when it leads to
    more folding.

    Generalize ScalarEvolution's isOffsetOf to recognize offsetof on
    arrays. Rename getAllocSizeExpr to getSizeOfExpr, and getFieldOffsetExpr
    to getOffsetOfExpr, for consistency with analagous ConstantExpr routines.

    Make the target-dependent folder promote GEP array indices to
    pointer-sized integers, to make implicit casting explicit and exposed
    to subsequent folding.

    And add a bunch of testcases for this new functionality, and a bunch
    of related existing functionality.

    fix rdar://7590304, an infinite loop in instcombine.  In the invoke
    case, instcombine can't zap the invoke for fear of changing the CFG.
    However, we have to do something to prevent the next iteration of
    instcombine from inserting another store -> undef before the invoke
    thereby getting into infinite iteration between dead store elim and
    store insertion.

    Just zap the callee to null, which will prevent the next iteration
    from doing anything.

    it and no need to specify the calling convention.

    Keep iterating over all uses when meeting a phi node in AllUsesOfValueWillTrapIfNull().

    This bug was exposed by my inliner cost changes in r94615, and caused failures
    of lencod on most architectures when building with LTO.

    This patch fixes lencod and 464.h264ref on x86-64 (and likely others).

    MC/X86: Add a nice X86 assembler matcher test case from Kevin Enderby.
     - This test case is auto generated, and has been verified to round-trip
       correctly through llvm-mc by checking the assembled .o file before and after
       piping through llvm-mc. It will be extended over time as the matcher grows
       support for more instructions.

    Preserve load alignment in instcombine transformations.  I've been unable to
    create a testcase where this matters.  The select+load transformation only
    occurs when isSafeToLoadUnconditionally is true, and in those situations,
    instcombine also changes the underlying objects to be aligned.  This seems
    like a good idea regardless, and I've verified that it doesn't pessimize
    the subsequent realignment.

    Having RHSKnownZero and RHSKnownOne be alternative names for KnownZero and KnownOne
    (via APInt &RHSKnownZero = KnownZero, etc) seems dangerous and confusing to me: it
    is easy not to notice this, and then wonder why KnownZero/RHSKnownZero changed
    underneath you when you modified RHSKnownZero/KnownZero etc.  So get rid of this.
    No intended functionality change (tested with "make check" + llvm-gcc bootstrap).

    Assign the ordering of SDNodes in a much less intrusive fashion. After the
    "visit*" method is called, take the newly created nodes, walk them in a DFS
    fashion, and if they don't have an ordering set, then give it one.

commit a64c74890ef37c607b3f1742abb5b1af65342afa
Author: Dan Gohman <gohman@apple.com>
Date:   Thu Jan 28 18:08:26 2010 +0000

    Remove the folding rule
      getelementptr (i8* inttoptr (i64 1 to i8*), i32 -1)
      to
      inttoptr (i64 0 to i8*)
    from the VMCore constant folder. It didn't handle sign-extension properly
    in the case where the source integer is smaller than a pointer size. And,
    it relied on an assumption about sizeof(i8).

    The Analysis constant folder still folds these kinds of things; it has
    access to TargetData, so it can do them right.

    Add a testcase which tests that the VMCore constant folder doesn't
    miscompile this, and that the Analysis folder does fold it.

    Remove SCEVAllocSizeExpr and SCEVFieldOffsetExpr, and in their place
    use plain SCEVUnknowns with ConstantExpr::getSizeOf and
    ConstantExpr::getOffsetOf constants. This eliminates a bunch of
    special-case code.

    Also add code for pattern-matching these expressions, for clients that
    want to recognize them.

    Move ScalarEvolution's logic for expanding array and vector sizeof
    expressions into an element count times the element size, to expose
    the multiplication to subsequent folding, into the regular constant
    folder.

    "GVMaterializer". Code that used to need a ModuleProvider to materialize
    Functions can now materialize the Functions directly. Functions no longer use a
    magic linkage to record that they're materializable; they simply ask the
    GVMaterializer.

    Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
    the functions that refer to it. Instead, because Module now exposes the same
    functionality ModuleProvider used to, we store a Module* in any
    LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
    other languages still use the ModuleProvider concept.  It would probably be
    worth some time to update them to follow the C++ more closely, but I don't
    intend to do it.

    Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.

    even when -tailcallopt is not specified and it does not require changing ABI.
    First case is the most trivial one. Perform tail call optimization when both
    the caller and callee do not return values and when the callee does not take
    any input arguments.

    Eliminate target hook IsEligibleForTailCallOptimization.

    Target independent isel should always pass along the "tail call" property. Change
    target hook LowerCall's parameter "isTailCall" into a refernce. If the target
    decides it's impossible to honor the tail call request, it should set isTailCall
    to false to make target independent isel happy.

    Fix inline cost predictions with SCIENCE.

    After running a batch of measurements, it is clear that the inliner metrics
    need some adjustments:

    Own argument bonus:       20 -> 5
    Outgoing argument penalty: 0 -> 5
    Alloca bonus:             10 -> 5
    Constant instr bonus:      7 -> 5
    Dead successor bonus:     40 -> 5*(avg instrs/block)

    The new cost metrics are generaly 25 points higher than before, so we may need
    to move thresholds.

    With this change, InlineConstants::CallPenalty becomes a political correction:

    if (!isa<IntrinsicInst>(II) && !callIsSmall(CS.getCalledFunction()))
      NumInsts += InlineConstants::CallPenalty + CS.arg_size();

    The code size is accurately modelled by CS.arg_size(). CallPenalty is added
    because calls tend to take a long time, so it may not be worth it to inline a
    function with lots of calls.

    All of the political corrections are in the InlineConstants namespace:
    IndirectCallBonus, CallPenalty, LastCallToStaticBonus, ColdccPenalty,
    NoreturnPenalty.

    Revert test polarity to match comment and desired outcome. Remove undeserved bonus.

    A GEP with all constant indices is already considered free by
    analyzeBasicBlock(), so don't give it an extra bonus in
    CountCodeReductionForAlloca().

    This patch should remove a small positive bias toward inlining functions with
    variable-index GEPs, and remove a smaller negative bias from functions with
    all-constant index GEPs.

    Remove dead code.

    Functions containing indirectbr are marked NeverInline by analyzeBasicBlock(),
    so there is no point in giving indirectbr special treatment in
    CountCodeReductionForConstant. It is never called.

    No functional change intended.

    Eliminate SetDirective, and replace it with HasSetDirective.
    Default HasSetDirective to true, since most targets have it.

    The targets that claim to not have it probably do, or it is
    spelled differently. These include Blackfin, Mips, Alpha, and
    PIC16.  All of these except pic16 are normal ELF targets, so
    they almost certainly have it.

    Check in the first big step of rewriting DAGISelEmitter to
    produce a table based matcher instead of gobs of C++ Code.

    Though it's not done yet, the shrinkage seems promising,
    the table for the X86 ISel is 75K and still has a lot of
    optimization to come (compare to the ~1.5M of .o generated
    the old way, much of which will go away).

    The code is currently disabled by default (the #if 0 in
    DAGISelEmitter.cpp).  When enabled it generates a dead
    SelectCode2 function in the DAGISel Header which will
    eventually replace SelectCode.

    There is still a lot of stuff left to do, which are
    documented with a trail of FIXMEs.

    remove the DisablePatternForFastISel predicate, which is a check
    that predated -fast-isel which attempted to speed up the dag pattern
    matchers at -O0.  Since fast-isel is around, this is basically
    obsolete and removing it shrinks the generated dag isels.

    When complicated expressions are broken down into subexpressions
    with multiplication by constants distributed through, occasionally
    those subexpressions can include both x and -x. For now, if this
    condition is discovered within LSR, just prune such cases away,
    as they won't be profitable. This fixes a "zero allocated in a
    base register" assertion failure.

    In rememberInstruction, if the value being remembered is the

    Fix PR6283.

    When coalescing with a physreg, remember to add imp-def and imp-kill when
    dealing with sub-registers.

    Also fix a related bug in VirtRegRewriter where substitutePhysReg may
    reallocate the operand list on an instruction and invalidate the reg_iterator.
    This can happen when a register is mentioned twice on the same instruction.

    Teach MachineFrameInfo to track maximum alignment while stack objects are being
    created. This ensures it's updated at all time. It means targets which perform
    dynamic stack alignment would know whether it is required and whether frame
    pointer register cannot be made available register allocation.
    This is a fix for rdar://7625239. Sorry, I can't create a reasonably sized test
    case.

    Enable the inlinehint attribute in the Inliner.

    Functions explicitly marked inline will get an inlining threshold slightly
    more aggressive than the default for -O3. This means than -O3 builds are
    mostly unaffected while -Os builds will be a bit bigger and faster.

    The difference depends entirely on how many 'inline's are sprinkled on the
    source.

    In the CINT2006 suite, only these tests are significantly affected under -Os:

                   Size   Time
    471.omnetpp   +1.63% -1.85%
    473.astar     +4.01% -6.02%
    483.xalancbmk +4.60%  0.00%

    Note that 483.xalancbmk runs too quickly to give useful timing results.

    Reworked the Intel disassembler to support instructions
    whose opcodes extend into the ModR/M field using the
    Form field of the instruction rather than by special
    casing each instruction.  Commented out the special
    casing of VMCALL, which is the first instruction to use
    this special form.  While I was in the neighborhood,
    added a few comments for people modifying the Intel
    disassembler.

    When save/restoring CR at prolog/epilog, in a large
    stack frame, the prolog/epilog code was using the same
    register for the copy of CR and the address of the save slot.  Oops.
    This is fixed here for Darwin, sort of, by reserving R2 for this case.
    A better way would be to do the store before the decrement of SP,
    which is safe on Darwin due to the red zone.

    SVR4 probably has the same problem, but I don't know how to fix it;
    there is no red zone and R2 is already used for something else.
    I'm going to leave it to someone interested in that target.

    Better still would be to rewrite the CR-saving code completely;
    spilling each CR subregister individually is horrible code.

    Rewrite handling of DBG_VALUE; previous algorithm
    didn't handle
    X =
    Y<dead> = use X
    DBG_VALUE(X)
    I was hoping to avoid this approach as it's slower,
    but I don't think it can be done.

    1. modernize the constantmerge pass, using densemap/smallvector.
    2. don't bother trying to merge globals in non-default sections,
       doing so is quite dubious at best anyway.
    3. fix a bug reported by Arnaud de Grandmaison where we'd try to
       merge two globals in different address spaces.

    Add a new pass on machine instructions to optimize away PHI cycles that
    reduce down to a single value.  InstCombine already does this transformation
    but DAG legalization may introduce new opportunities.  This has turned out to
    be important for ARM where 64-bit values are split up during type legalization:
    InstCombine is not able to remove the PHI cycles on the 64-bit values but
    the separate 32-bit values can be optimized.  I measured the compile time
    impact of this (running llc on 176.gcc) and it was not significant.

    Add and commonize encoder support for all immediates.
    Stub out some dummy fixups to make things work.

    We can now emit fixups like this:
    	subl	$20, %esp               ## encoding: [0x83,0xec,A]
                                            ##   fixup A - offset: 2, value: 20, kind: fixup_1byte_imm

    Emitting $20 as a single-byte fixup to be later resolved
    by the assembler is ridiculous of course (vs just emitting
    the byte) but this is a failure of the matcher, which
    should be producing an imm of 20, not an MCExpr of 20.

    Rename ValueRequiresCast to ShouldOptimizeCast, to better reflect
    what it does.  Enhance it to return false to optimizing vector
    sign extensions from vector comparisions, which is the idiom used
    to get a splatted vector for a vector comparison.

    Doing this breaks vector-casts.ll, add some compensating
    transformations to handle the important case they cover without
    depending on this canonicalization.

    This fixes rdar://7434900 a serious pessimization of vector compares.

    The previous fix of widening divides that trap was too fragile as it depends on custom
    lowering and requires that certain types exist in ValueTypes.h.  Modified widening to
    check if an op can trap and if so, the widening algorithm will apply only the op on
    the defined elements.  It is safer to do this in widening because the optimizer can't
    guarantee removing unused ops in some cases.

commit 1ca197830a1a1906a5657c9e9c52977510106e39
Author: Bob Wilson <bob.wilson@apple.com>
Date:   Wed Feb 10 22:58:57 2010 +0000

    Delete dead PHI machine instructions.  These can be created due to type
    legalization even when the IR-level optimizer has removed dead phis, such
    as when the high half of an i64 value is unused on a 32-bit target.
    I had to adjust a few test cases that had dead phis.
    This is a partial fix for Radar 7627077.

    print on the same line as the instruction again:

Date:   Tue Feb 9 23:22:43 2010 +0000

    Adds a JIT based exception handling example to the examples directory.
    Both zero cost example domain specific, and C++ foreign exception handling are
    shown. The example's documentation fully explains how to run the example.

    Notes:

    1)   The code uses an extremely simple type info model.
    2)   Only a single landing pad is used per unwind edge
         (one call to llvm.eh.selector)
    3)   llvm.eh.selector support for filter arguments is not given.
    4)   llvm.eh.typeid.for is not used.
    5)   Forced unwind behavior is not supported.
    6)   Very little if any error handling is given.
    7)   __attribute__((__aligned__)) is used.
    8)   The code uses parts from the llvm compiler-rt project and
         the llvm Kaleidoscope example.
    9)   The code has not been ported or tested on WINDOWS.
    10)  The code was not tested with a cmake build.
    11)  The code was tested for a debug build on 32bit X86 CentOS LINUX,
         and both a debug and release build on OS X 10.6.2 (64bit).

    Radar 7417921

    tMOVCCi pattern only valid for low registers, as the Thumb1 mov immediate to
    register instruction only works with low registers. Allowing high registers
    for the instruction resulted in the assembler choosing the wide (32-bit)
    encoding for the mov, but LLVM though the instruction was only 16 bits wide,
    so offset calculations for constant pools became incorrect, leading to
    out of range constant pool entries.

Author: Lang Hames <lhames@gmail.com>
Date:   Tue Feb 9 00:50:27 2010 +0000

    Fixed a bug in the PBQP allocator's findCoalesces method.

    Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with.

    GetBlockAddressSymbol.  Do so.

    When CodeGen'ing unoptimized code, there may be unfolded constant expressions
    in global initializers. Instead of aborting, attempt to fold them on the
    spot. If folding succeeds, emit the folded expression instead.

    Give DwarfPrinter a protected (but not virtual) destructor.  Cppcheck
    warns about this base class not having a virtual destructor, but since
    this class has no virtual methods and neither it or the types derived
    from it has a destructor, a protected trivial destructor will do (and
    shuts cppcheck up) the trick without the cost of introducing a vtable.

    Run codegen dce pass for all targets at all optimization levels. Previously it's
    only run for x86 with fastisel. I've found it being very effective in
    eliminating some obvious dead code as result of formal parameter lowering
    especially when tail call optimization eliminated the need for some of the loads
    from fixed frame objects. It also shrinks a number of the tests. A couple of
    tests no longer make sense and are now eliminated.

    This time it's for real! I am going to hook this up in the frontends as well.

    The inliner has some experimental heuristics for dealing with the inline hint.
    When given a -respect-inlinehint option, functions marked with the inline
    keyword are given a threshold just above the default for -O3.

    We need some experiments to determine if that is the right thing to do.

    Teach SimplifyCFG about magic pointer constants.

    Weird code sometimes uses pointer constants other than null. This patch
    teaches SimplifyCFG to build switch instructions in those cases.

    Code like this:

    void f(const char *x) {
      if (!x)
        puts("null");
      else if ((uintptr_t)x == 1)
        puts("one");
      else if (x == (char*)2 || x == (char*)3)
        puts("two");
      else if ((intptr_t)x == 4)
        puts("four");
      else
        puts(x);
    }

    Now becomes a switch:

    define void @f(i8* %x) nounwind ssp {
    entry:
      %magicptr23 = ptrtoint i8* %x to i64            ; <i64> [#uses=1]
      switch i64 %magicptr23, label %if.else16 [
        i64 0, label %if.then
        i64 1, label %if.then2
        i64 2, label %if.then9
        i64 3, label %if.then9
        i64 4, label %if.then14
      ]

    Note that LLVM's own DenseMap uses magic pointers.

    When the scheduler unfold a load folding instruction it move some of the predecessors to the unfolded load. It decides what gets moved to the load by checking whether the new load is using the predecessor as an operand. The check neglects the cases whether the predecessor is a flagged scheduling unit.

    An empty global constant (one of size 0) may have a section immediately

    Do not reassociate expressions with i1 type.  SimplifyCFG converts some
    short-circuited conditions to AND/OR expressions, and those expressions
    are often converted back to a short-circuited form in code gen.  The
    original source order may have been optimized to take advantage of the
    expected values, and if we reassociate them, we change the order and
    subvert that optimization.  Radar 7497329.

    Indirect tail call has to go through a call preserved register since it's after callee register pops. X86 isel lowering is using EAX / R11 and it was somehow adding that to function live out. That prevented the real function return register from being added to the function live out list and bad things happen.
    This fixes 483.xalancbmk (with tail call opt).

commit 66b7149074808f51fd6365b509028ff862a05108
Author: Bob Wilson <bob.wilson@apple.com>
Date:   Wed Feb 3 17:23:56 2010 +0000

    Adjust the heuristics used to decide when SROA is likely to be profitable.
    The SRThreshold value makes perfect sense for checking if an entire aggregate
    should be promoted to a scalar integer, but it is not so good for splitting
    an aggregate into its separate elements.  A struct may contain a large embedded
    array along with some scalar fields that would benefit from being split apart
    by SROA.  Even if the total aggregate size is large, it may still be good to
    perform SROA.  Thus, the most important piece of this patch is simply moving
    the aggregate size comparison vs. SRThreshold so that it guards only the
    aggregate promotion.

    We have also been checking the number of elements to decide if an aggregate
    should be split up.  The limit of "SRThreshold/4" seemed rather arbitrary,
    and I don't think it's very useful to derive this limit from SRThreshold
    anyway.  I've collected some data showing that the current default limit of
    32 (since SRThreshold defaults to 128) is a reasonable cutoff for struct
    types.  One thing suggested by the data is that distinguishing between structs
    and arrays might be useful.  There are (obviously) a lot more large arrays
    than large structs (as measured by the number of elements and not the total
    size -- a large array inside a struct still counts as a single element given
    the way we do SROA right now).  Out of 8377 arrays where we successfully
    performed SROA while compiling a large set of benchmarks, only 16 of them had
    more than 8 elements.  And, for those 16 arrays, it's not at all clear that
    SROA was actually beneficial.  So, to offset the compile time cost of
    investigating more large structs for SROA, the patch lowers the limit on array
    elements to 8.

    This fixes Apple Radar 7563690.

    Added another version of the X86 assembler matcher test case.
    This test case is different subset of the full auto generated test case, and a
    larger subset that is in x86_32-bit.s (that set will encode correctly).  These
    instructions can pass though llvm-mc as it were a logical cat(1) and then
    reassemble to the same instruction.  It is useful as we bring up the parser and
    matcher so we don't break things that currently work.

    where callee's arguments are already in the caller's own caller's stack and
    they line up perfectly. e.g.

    extern int foo(int a, int b, int c);

    int bar(int a, int b, int c) {
      return foo(a, b, c);
    }

    Changed to Chris Lattner's suggested approach, which
    merely stubs out the blocks-based disassembly functions
    if the library wasn't built with blocks, which allows a
    constant .exports file and also properly deals with
    situations in which the compiler used to build a client
    is different from the compiler used to build the library.

    Generalize target-independent folding rules for sizeof to handle more
    cases, and implement target-independent folding rules for alignof and
    offsetof. Also, reassociate reassociative operators when it leads to
    more folding.

    Generalize ScalarEvolution's isOffsetOf to recognize offsetof on
    arrays. Rename getAllocSizeExpr to getSizeOfExpr, and getFieldOffsetExpr
    to getOffsetOfExpr, for consistency with analagous ConstantExpr routines.

    Make the target-dependent folder promote GEP array indices to
    pointer-sized integers, to make implicit casting explicit and exposed
    to subsequent folding.

    And add a bunch of testcases for this new functionality, and a bunch
    of related existing functionality.

    fix rdar://7590304, an infinite loop in instcombine.  In the invoke
    case, instcombine can't zap the invoke for fear of changing the CFG.
    However, we have to do something to prevent the next iteration of
    instcombine from inserting another store -> undef before the invoke
    thereby getting into infinite iteration between dead store elim and
    store insertion.

    Just zap the callee to null, which will prevent the next iteration
    from doing anything.

    Added the enhanced disassembly library's implementation and

    details of operand parsing, but the basic functionality is
    there and usable.

       piping through llvm-mc. It will be extended over time as the matcher grows
       support for more instructions.

    Preserve load alignment in instcombine transformations.  I've been unable to
    create a testcase where this matters.  The select+load transformation only
    occurs when isSafeToLoadUnconditionally is true, and in those situations,
    instcombine also changes the underlying objects to be aligned.  This seems
    like a good idea regardless, and I've verified that it doesn't pessimize
    the subsequent realignment.

    Having RHSKnownZero and RHSKnownOne be alternative names for KnownZero and KnownOne
    (via APInt &RHSKnownZero = KnownZero, etc) seems dangerous and confusing to me: it
    is easy not to notice this, and then wonder why KnownZero/RHSKnownZero changed
    underneath you when you modified RHSKnownZero/KnownZero etc.  So get rid of this.
    No intended functionality change (tested with "make check" + llvm-gcc bootstrap).

Author: Dan Gohman <gohman@apple.com>
Date:   Thu Jan 28 18:08:26 2010 +0000

    Remove the folding rule
      getelementptr (i8* inttoptr (i64 1 to i8*), i32 -1)
      to
      inttoptr (i64 0 to i8*)
    from the VMCore constant folder. It didn't handle sign-extension properly
    in the case where the source integer is smaller than a pointer size. And,
    it relied on an assumption about sizeof(i8).

    The Analysis constant folder still folds these kinds of things; it has
    access to TargetData, so it can do them right.

    Add a testcase which tests that the VMCore constant folder doesn't
    miscompile this, and that the Analysis folder does fold it.

    Remove SCEVAllocSizeExpr and SCEVFieldOffsetExpr, and in their place
    use plain SCEVUnknowns with ConstantExpr::getSizeOf and
    ConstantExpr::getOffsetOf constants. This eliminates a bunch of
    special-case code.

    Also add code for pattern-matching these expressions, for clients that
    want to recognize them.

    Move ScalarEvolution's logic for expanding array and vector sizeof
    expressions into an element count times the element size, to expose
    the multiplication to subsequent folding, into the regular constant
    folder.

commit 752ff1fb26fc819498de04d342d496f146100f2a
Author: Jeffrey Yasskin <jyasskin@google.com>
Date:   Wed Jan 27 20:34:15 2010 +0000

    Kill ModuleProvider and ghost linkage by inverting the relationship between
    Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
    GlobalValues now, and doesn't provide modules, it's renamed to
    "GVMaterializer". Code that used to need a ModuleProvider to materialize
    Functions can now materialize the Functions directly. Functions no longer use a
    magic linkage to record that they're materializable; they simply ask the
    GVMaterializer.

    Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
    the functions that refer to it. Instead, because Module now exposes the same
    functionality ModuleProvider used to, we store a Module* in any
    LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
    other languages still use the ModuleProvider concept.  It would probably be
    worth some time to update them to follow the C++ more closely, but I don't
    intend to do it.

    Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.

    Eliminate target hook IsEligibleForTailCallOptimization.

    Target independent isel should always pass along the "tail call" property. Change
    target hook LowerCall's parameter "isTailCall" into a refernce. If the target
    decides it's impossible to honor the tail call request, it should set isTailCall
    to false to make target independent isel happy.

    use EmitLinkage for functions as well as globals.  One output
    change is that we now use ".linkonce discard" for global variables
    instead of ".linkonce samesize".  These should be the same, just less
    strict.  If anyone is interested in mcizing MCSection for COFF targets,
    this should be easy to fix.

commit fcd69992ced3281fc9d0630806d30be2feaab5a2
Author: Jakob Stoklund Olesen <stoklund@2pi.dk>
Date:   Tue Jan 26 23:21:56 2010 +0000

    Fix inline cost predictions with SCIENCE.

    After running a batch of measurements, it is clear that the inliner metrics
    need some adjustments:

    Own argument bonus:       20 -> 5
    Outgoing argument penalty: 0 -> 5
    Alloca bonus:             10 -> 5
    Constant instr bonus:      7 -> 5
    Dead successor bonus:     40 -> 5*(avg instrs/block)

    The new cost metrics are generaly 25 points higher than before, so we may need
    to move thresholds.

    With this change, InlineConstants::CallPenalty becomes a political correction:

    if (!isa<IntrinsicInst>(II) && !callIsSmall(CS.getCalledFunction()))
      NumInsts += InlineConstants::CallPenalty + CS.arg_size();

    The code size is accurately modelled by CS.arg_size(). CallPenalty is added
    because calls tend to take a long time, so it may not be worth it to inline a
    function with lots of calls.

    All of the political corrections are in the InlineConstants namespace:
    IndirectCallBonus, CallPenalty, LastCallToStaticBonus, ColdccPenalty,
    NoreturnPenalty.

    A GEP with all constant indices is already considered free by
    analyzeBasicBlock(), so don't give it an extra bonus in

    This patch should remove a small positive bias toward inlining functions with
    variable-index GEPs, and remove a smaller negative bias from functions with
    all-constant index GEPs.

    The targets that claim to not have it probably do, or it is

    Tweak the way appendModuleInlineAsm works, so you aren't obliged
    to append a newline when using setModuleInlineAsm in case later
    someone calls appendModuleInlineAsm - make newline handling fully
    automatic.  In case anyone is wondering there is only one user of
    appendModuleInlineAsm: the dragonegg plugin.

    Remove unneeded checks from configure.ac.

    HAVE_{BI,STD,FWD}_ITERATOR and HAVE_NAMESPACES were not used in the code.
    bison and flex are no longer used.
    CAN_DLOPEN_SELF was never used either.
    AC_PROG_LIBTOOL is not needed since we don't use libtool, we only need the
    libltdl checks for dlopen.
    Add check for AR, it used to be done by AC_PROG_LIBTOOL.
    AC_TYPE_SIGNAL is deprecated, follow autoupdate's suggestion and replace with
    void.
    Remove unused m4 files.
    Configure can now be generated using autoconf 2.65 too, without any warnings!

    Move getJTISymbol from MachineJumpTableInfo to MachineFunction,
    which is more convenient, and change getPICJumpTableRelocBaseExpr
    to take a MachineFunction to match.

    Next, move the X86 code that create a PICBase symbol to
    X86TargetLowering::getPICBaseSymbol from
    X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific
    library.  This eliminates a 'gross hack', and allows us to
    implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now
    calls it.

    This in turn allows us to eliminate the
    X86AsmPrinter::printPICJumpTableSetLabel method, which was the
    only overload of printPICJumpTableSetLabel.

    jump table entry kind, instead of overloading

    Fix the the ceiling-division used in computing the MaxBECount so that it doesn't
    have trouble with an intermediate add overflowing. Also, be more conservative
    about the case where the induction variable in an SLT loop exit can step past
    the RHS of the SLT and overflow in a single step.

    Make getSignedRange more aggressive, to recover for some common cases which

commit f64ffc4e7521176024d0c53f2e3a702c6de98133
Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Jan 25 23:26:13 2010 +0000

    Rearrange handling of jump tables.  Highlights:
    1. MachineJumpTableInfo is now created lazily for a function the first time
       it actually makes a jump table instead of for every function.
    2. The encoding of jump table entries is now described by the
       MachineJumpTableInfo::JTEntryKind enum.  This enum is determined by the
       TLI::getJumpTableEncoding() hook, instead of by lots of code scattered
       throughout the compiler that "knows" that jump table entries are always
       32-bits in pic mode (for example).
    3. The size and alignment of jump table entries is now calculated based on
       their kind, instead of at machinefunction creation time.

    Future work includes using the EntryKind in more places in the compiler,
    eliminating other logic that "knows" the layout of jump tables in various
    situations.

    Change Value::getUnderlyingObject to have the MaxLookup value specified as a
    parameter with a default value, instead of just hardcoding it in the
    implementation.  The limit of MaxLookup = 6 was introduced in r69151 to fix
    a performance problem with O(n^2) behavior in instcombine, but the scalarrepl
    pass is relying on getUnderlyingObject to go all the way back to an AllocaInst.
    Making the limit part of the method signature makes it clear that by default
    the result is limited and should help avoid similar problems in the future.
    This fixes pr6126.

    linux/ppc does use alignment in bytes, not pow-2.  This fixes PR6129.
    It looks like linux/arm and linux/mips have the same setting, which
    are probably wrong.  Someone who cares about ARM and MIPS should
    investigate with the testcase in PR6129.

    Remove the '-disable-scheduling' flag and replace it with the 'source' option of
    the '-pre-RA-sched' flag. It actually makes more sense to do it this way. Also,
    keep track of the SDNode ordering by default. Eventually, we would like to make
    this ordering a way to break a "tie" in the scheduler. However, doing that now
    breaks the "CodeGen/X86/abi-isel.ll" test for 32-bit Linux.

    Modified the register matcher function in AsmMatcher to
    be static.  Also made it possible for clients to get it
    and no other functions from ...GenAsmMatcher.inc by
    defining REGISTERS_ONLY before including GenAsmMatcher.inc.
    This sets the stage for target-specific lexers that can
    identify registers and return AsmToken::Register as
    appropriate.

Date:   Fri Jan 22 21:11:06 2010 +0000

    For blocks that are not loop headers, just print their loop depth and header BB.
    For loop headers, print Inner loop along with the other stuff so it doesn't take
    an extra line.  We now get stuff like this:

    LBB1_4:                                                     ## %land.end
                                                                ##   in Loop: Header=BB1_1 Depth=1
            notb    %al
            testb   $1, %al
            jne     LBB1_8

    and:

    LBB1_6:                                                     ## %while.cond7
                                                                ## Inner Loop Header: Depth=3
                                                                ##     Inside Loop BB1_5 Depth 2
                                                                ##   Inside Loop BB1_1 Depth 1

    which still isn't great for loop headers, but is much less verbose.

    Fix TimeValue::now() on Unix.

    TimeValue()::now().toEpochTime() is supposed to be the same as time(),

    didn't add PosixZeroTime!
    Add a unittest to check this works.

    Add the ability for MCStreamer to emit comments on the same line as directives.
    Switch over the asm-verbose comment for double values to use it.  We now get:

    _x:
    	.long	343597384                                   ## double 1.231200e+02
    	.long	1079953326

    For example, note that the comment is on the same line as the .long.  Woo.

    Stop building RTTI information for *most* llvm libraries.  Notable
    missing ones are libsupport, libsystem and libvmcore.  libvmcore is
    currently blocked on bugpoint, which uses EH.  Once it stops using
    EH, we can switch it off.

    This #if 0's out 3 unit tests, because gtest requires RTTI information.
    Suggestions welcome on how to fix this.

    It turns out that this #include is needed because otherwise
    ValueMapper.cpp ends up calling an out of line
    __ZNK4llvm12PATypeHolder3getEv, which is a template and llvm-config
    determines arbitrarily to use the one in libipo.  This sucks, but
    keeping the #include is a reasonable workaround.

    Re-implement the main strength-reduction portion of LoopStrengthReduction.
    This new version is much more aggressive about doing "full" reduction in
    cases where it reduces register pressure, and also more aggressive about
    rewriting induction variables to count down (or up) to zero when doing so
    reduces register pressure.

    It currently uses fairly simplistic algorithms for finding reuse
    opportunities, but it introduces a new framework allows it to combine
    multiple strategies at once to form hybrid solutions, instead of doing
    all full-reduction or all base+index.

    eliminate the GVStubs and HiddenGVStubs maps, and use
    MachineModuleInfoMachO instead.  This eliminates two sources
    of nondeterministic output in the ppc backend, but function
    stubs are still bad.

    When doing address-mode sinking, expand the base register first, rather
    than the scaled register. This makes it more likely that subsequent
    AddrModeMatcher queries will match the new address the same way as the
    old, instead of accidentally matching what had been the base register
    as the new scaled register, and then failing to match the scaled register.
    This fixes some problems with address-mode sinking multiple muls into a
    block, which will be a lot more common with some upcoming
    LoopStrengthReduction changes.

    give MCAsmInfo a 'has little endian' bit.  This is unfortunate, but
    I really want clients of the streamer to be able to say "emit this
    64-bit integer" and have it get broken down right by the streamer.

    I may change this in the future, we'll see how it works out.

    For aligned load/store instructions, it's only required to know whether a
    function can support dynamic stack realignment. That's a much easier question
    to answer at instruction selection stage than whether the function actually
    will have dynamic alignment prologue. This allows the removal of the
    stack alignment heuristic pass, and improves code quality for cases where
    the heuristic would result in dynamic alignment code being generated when
    it was not strictly necessary.

    The change in r90189 adds a link in a directory outside the iPhone platform
    directory when building the llvmCore_Embedded project.  Fix this by putting
    the iPhone platform directory into DEST_DIR instead of DEST_ROOT.  I also
    noticed what appears to be an unintentional use of DEVELOPER_BIN instead of
    DEVELOPER_DIR, so I fixed that and changed to use DEVELOPER_DIR in some places
    that were hardcoded to "Developer".  Finally, the other changes here allowed
    some refactoring and simplification, which I have done.

commit 42a203b73bbc908258a8c2cee070559c300f3bfe
Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Jan 19 05:38:33 2010 +0000

    Now that we have everything nicely factored (e.g. asmprinter is not
    doing global variable classification anymore) and hookized, sink almost
    all target targets global variable emission code into AsmPrinter and out
    of each target.

    Some notes:

    1. PIC16 does completely custom and crazy stuff, so it is not changed.
    2. XCore has some custom handling for extra directives.  I'll look at it next.
    3. This switches linux/ppc to use .globl instead of .global.  If .globl is
       actually wrong, let me know and I'll fix it.
    4. This makes linux/ppc get a lot of random cases right which were obviously
       wrong before, it is probably now a bit healthier.
    5. Blackfin will probably start getting .comm and other things that it didn't
       before.  If this is undesirable, it should explicitly opt out of these
       things by clearing the relevant fields of MCAsmInfo.

    This leads to a nice diffstat:

    more cleanups.  Emit the .local directive even on cygwin/mingw.
    I'm not sure that this is correct, but it causes no test failures,
    and just emitting a .comm without protecting its linkage somehow
    is surely not right.

Date:   Tue Jan 19 04:39:15 2010 +0000

    hoist handling of external globals and special globals up to common code.
    This makes a similar code dead in all the other targets, I'll clean it up
    in a bit.

    This also moves handling of lcomm up before acquisition of a section,
    since lcomm never needs a section.

Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Jan 19 03:06:01 2010 +0000

    fix a significant difference between llvm and gcc on ELF systems:
    GCC would put weak zero initialized mutable data in the .bss section,
    we would put it into a crasy '.gnu.linkonce.b.test,"aw",@nobits'
    section.  Fixing this will allow simplifications next up.

    introduce a section kind for common linkage.  Use this to slightly
    simplify and commonize some of the asmprinter logic for globals.

    This also avoids printing the MCSection for .zerofill, which broke
    the llvm-gcc build.

    Cleanup handling of .zerofill on darwin:

    1. TargetLoweringObjectFileMachO should decide if something
       goes in zerofill instead of having every target do it.
    2. TargetLoweringObjectFileMachO should assign said symbols to
       the right MCSection, the asmprinters should just emit to the
       right section.
    3. Since all zerofill stuff goes through mcstreamer anymore,
       MAI can have a bool "haszerofill" instead of having the textual
       directive to emit.

    Canonicalize -1 - x to ~x.

    Instcombine does this but apparently there are situations where this pattern will escape the optimizer and / or created by isel. Here is a case that's seen in JavaScriptCore:
      %t1 = sub i32 0, %a
      %t2 = add i32 %t1, -1
    The dag combiner pattern: ((c1-A)+c2) -> (c1+c2)-A
    will fold it to -1 - %a.

    The most significant encoding bit of GPR:$src or GPR:$dst was over-specified in
    the various MOV (register) instructions (16-bit Thumb), including tBRIND (the
    indirect branch).  Instead of '1', it should be specified as '?', because GPR
    only specifies the register class, which includes both hi-and-lo registers.

    Get MCSymbol out of the mangling business, and move all the logic
    to Mangler.  Now MCSymbol just decides whether to slap quotes around
    a symbol when printing it.

    This also fixes some weirdness where two MCSymbols could be created
    for the same symbol, if one needed to be mangled and got mangled to
    the other one.

    bugpoint doesn't need the mangler at all.  DisambiguateGlobalSymbols
    dates to a time when two different LLVM values could have the same
    name but different types.  Simplify it to just assign names to unnamed

    print/dumpWithDepth allows one to dump a DAG up to N levels deep.
    dump/printWithFullDepth prints the whole DAG, subject to a depth limit
    on 100 in the default case (to prevent infinite recursion).

    Have CannotYetSelect to a dumpWithFullDepth so it is clearer exactly
    what the non-matching DAG looks like.

    Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast).
    This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.
    It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument.

    Hook up llc's -filetype=obj to use MCStreamer if an MCCodeEmitter is available.
    Remove most of old Mach-O Writer support, it has been replaced by MCMachOStreamer

    Further refactoring to completely remove MachOWriter and drive the object file
    writer with the AsmPrinter MCInst/MCSection logic is forthcoming.

    Change pre-regalloc tail duplication to only duplicate indirect branch blocks.
    The pre-regalloc pass caused some regressions in both compile time and
    performance of the generated code, and it did not improve performance, except
    for indirect branches.  I also moved the check for single-block loops to speed
    up the common case when running the taildup pass before reg allocation.

    Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast).
    This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.

    Split the TargetAsmParser "ParseInstruction" interface in half:
    the new ParseInstruction method just parses and returns a list of
    target operands.  A new MatchInstruction interface is used to
    turn the operand list into an MCInst.

    This requires new/deleting all the operands, but it also gives
    targets the ability to use polymorphic operands if they want to.

    Don't fold insufficiently aligned ldr/str into ldm/stm instructions.

    An unaligned ldr causes a trap, and is then emulated by the kernel with
    awesome performance. The darwin kernel does not emulate unaligned ldm/stm
    Thumb2 instructions, so don't generate them.

    This fixes the miscompilation of Multisource/Applications/JM/lencod for Thumb2.

    Generating unaligned ldr/str pairs from a 16-bit aligned memcpy is probably
    also a bad idea, but that is beyond the scope of this patch.

    When the visitSub method was split into visitSub and visitFSub, this xform was
    added to the FSub version. However, the original version of this xform guarded
    against doing this for floating point (!Op0->getType()->isFPOrFPVector()).

    This is causing LLVM to perform incorrect xforms for code like:

    void func(double *rhi, double *rlo, double xh, double xl, double yh, double yl){
      double mh, ml;
      double c = 134217729.0;
      double up, u1, u2, vp, v1, v2;

      up = xh*c;
      u1 = (xh - up) + up;
      u2 = xh - u1;

      vp = yh*c;
      v1 = (yh - vp) + vp;
      v2 = yh - v1;

      mh = xh*yh;
      ml = (((u1*v1 - mh) + (u1*v2)) + (u2*v1)) + (u2*v2);
      ml += xh*yl + xl*yh;

      *rhi = mh + ml;
      *rlo = (mh - (*rhi)) + ml;
    }

    The last line was optimized away, but rl is intended to be the difference
    between the infinitely precise result of mh + ml and after it has been rounded
    to double precision.

    an empty name (e.g. strip was run).

    use the new form of getNameWithPrefix, not makeNameProper.
    Among other things, this would do very weird things if the
    basic block name had (e.g.) a space in it on darwin:
    makeNameProper would add quotes, then the mcsymbol would
    escape the quotes.

    add new isSingleStringRef()/getSingleStringRef() methods to twine,
    and use them to avoid a copy of a string in getNameWithPrefix in
    the common case.  It seems like Value::setName and other places
    should use this as well?

    change Mangler::makeNameProper to return its result in a SmallVector
    instead of returning it in an std::string.  Based on this change:

    1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
    2. Change a bunch of targets to call makeNameProper with a smallstring,
       making several of them *much* more efficient.
    3. Rewrite Mangler::makeNameProper to not build names and then prepend
       prefixes, not use temporary std::strings, and to avoid other crimes.

    Add a quick pass to optimize sign / zero extension instructions. For targets where the pre-extension values are available in the subreg of the result of the extension, replace the uses of the pre-extension value with the result + extract_subreg.

    For now, this pass is fairly conservative. It only perform the replacement when both the pre- and post- extension values are used in the block. It will miss cases where the post-extension values are live, but not used.

    1) Use the new SimplifyInstructionsInBlock routine instead of the copy
    in JT.

    2) When cloning blocks for PHI or xor conditions, use
    instsimplify to simplify the code as we go.  This allows us to
    squish common cases early in JT which opens up opportunities for
    subsequent iterations, and allows it to completely simplify the
    testcase.

    Disable folding sext(trunc(x)) -> x (and other similar cast/cast cases) when the
    trunc has multiple uses.  Codegen is not able to coalesce the subreg case
    correctly and so this leads to higher register pressure and spilling (see PR5997).

    Reimplement getToken and SplitString as "StringRef helper functions"

    - getToken is modeled after StringRef::split but it can split on multiple
      separator chars and skips leading seperators.
    - SplitString is a StringRef::split variant for more than 2 elements with the
      same behaviour as getToken.

Date:   Mon Jan 11 04:05:13 2010 +0000

    Extend CanEvaluateZExtd to handle and/or/xor more aggressively in the
    BitsToClear case.  This allows it to promote expressions which have an
    and/or/xor after the lshr, promoting cases like test2 (from PR4216)
    and test3 (random extample extracted from a spec benchmark).

    clang now compiles the code in PR4216 into:

    _test_bitfield:                                             ## @test_bitfield
    	movl	%edi, %eax

    	movl	$4294902010, %ecx
    	andq	%rax, %rcx
    	orl	$32768, %edi
    	andq	$39936, %rdi
    	movq	%rdi, %rax
    	orq	%rcx, %rax
    	ret

    instead of:

    _test_bitfield:                                             ## @test_bitfield
    	movl	%edi, %eax
    	orl	$194, %eax
    	movl	$4294902010, %ecx
    	andq	%rax, %rcx
    	shrl	$8, %edi
    	orl	$128, %edi
    	shlq	$8, %rdi
    	andq	$39936, %rdi
    	movq	%rdi, %rax
    	orq	%rcx, %rax
    	ret

    which is still not great, but is progress.

Author: Chris Lattner <sabre@nondot.org>
Date:   Sun Jan 10 20:25:54 2010 +0000

    teach zext optimization how to deal with truncs that don't come from
    the zext dest type.  This allows us to handle test52/53 in cast.ll,
    and allows llvm-gcc to generate much better code for PR4216 in -m64
    mode:

    _test_bitfield:                                             ## @test_bitfield
    	orl	$32962, %edi
    	movl	%edi, %eax
    	andl	$-25350, %eax
    	ret

    This also fixes a bug handling vector extends, ensuring that the
    mask produced is a vector constant, not an integer constant.

    now that the cost model has changed, we can always consider
    elimination of a sign extend to be a win, which simplifies
    the client of CanEvaluateSExtd, and allows us to eliminate
    more casts (examples taken from real code).

    two changes:
    1) don't try to optimize a sext or zext that is only used by a trunc, let
       the trunc get optimized first.  This avoids some pointless effort in
       some common cases since instcombine scans down a block in the first pass.
    2) Change the cost model for zext elimination to consider an 'and' cheaper
       than a zext.  This allows us to do it more aggressively, and for the next
       patch to simplify the code quite a bit.

    Fixed linking of modules containing aliases to constant bitcasts.  Existing behaviour first tried to replace the aliases with the global that they aliased (rather than the bitcast), causing a crash on an assert because the types didn't match.  When this was fixed, it then did the same thing creating the new alias (creating an alias with a different type to its aliasee).

    Linking modules containing aliases to GEPs is still not quite right.  GEPs that are equivalent to bitcasts will be replaced by bitcasts, GEPs that are not will just break.  Aliases to GEPs that are not equivalent to bitcasts are horribly broken anyway (it might be worth adding an assert when creating the alias to prevent these being created; they just cause problems later).

    Fix a critical bug in 64-bit atomic operation lowering for 32-bit. The results of the cmpxchg8b instructions are being thrown away when it branches back to the top of the checking loop. This means the loop always compares against the old value and this can result in a dead lock.

    After further thought revert the patch to make fast-isel avoid
    putting relocations into the constant pool - this isn't needed
    for correctness and in the rare occasion it happens would pull
    us out of fast isel for the block.

    If fast-isel application startup time ever becomes an issue we
    can add better support for these addresses instead of bailing.

    Fix DFS number calculation for postdominators

    The DFS number calculation for postdominators was broken. In the case of
    multiple exits that form the post dominator root nodes, do not iterate over
    all exits, but start from the virtual root node. Otherwise bbs, that are not
    post dominated by any exit but by the virtual root node, will never be assigned
    a DFS number.

    fix a globalopt crash on 'bullet' (handling evaluation of a store
    to an element of a vector in a static ctor) which occurs with an
    unrelated patch I'm testing.  Annoyingly, EvaluateStoreInto basically
    does exactly the same stuff as InsertElement constant folding, but it
    now handles vectors, and you can't insertelement into a vector.  It
    would be 'really nice' if GEP into a vector were not legal.

    Teach dag combine to fold the following transformation more aggressively:
    (OP (trunc x), (trunc y)) -> (trunc (OP x, y))

    Unfortunately this simple change causes dag combine to infinite looping. The problem is the shrink demanded ops optimization tend to canonicalize expressions in the opposite manner. That is badness. This patch disable those optimizations in dag combine but instead it is done as a late pass in sdisel.

    This also exposes some deficiencies in dag combine and x86 setcc / brcond lowering. Teach them to look pass ISD::TRUNCATE in various places.

    Partially address a README by having functionattrs consider calls to
    memcpy, memset and other intrinsics that only access their arguments
    to be readnone if the intrinsic's arguments all point to local memory.
    This improves the testcase in the README to readonly, but it could in
    theory be made readnone, however this would involve more sophisticated
    analysis that looks through the memcpy.

    Teach instcombine's sext elimination logic to be more aggressive.
    Previously, instcombine would only promote an expression tree to
    the larger type if doing so eliminated two casts.  This is because
    a need to manually do the sign extend after the promoted expression
    tree with two shifts.  Now, we keep track of whether the result of
    the computation is going to be properly sign extended already.  If
    so, we can unconditionally promote the expression, which allows us
    to zap more sext's.

    This implements rdar://6598839 (aka gcc pr38751)

    Don't specify CR sub-registers as implicit defs of BL instructions.

    It is enough to give the super registers CR0, CR1, ..., and specifying the
    sub-registers as well causes confusion in the liveness computations.

    Remove livein checks from machine code verifier.

    A phi operand that is implicitly defined in a predecessor becomes an undefined
    register after phi elimination. This causes a lot of false positives when the
    verifier is checking if live-in registers are live-out from all predecessors.

    Removing the verifier checks seems like a better solution than insisting on
    IMPLICIT_DEF instructions in predecessor blocks.

    Add a SmallBitVector class, which mimics BitVector but uses only
    a single pointer (PointerIntPair) member. In "small" mode, the
    pointer field is reinterpreted as a set of bits. In "large" mode,
    the pointer points to a heap-allocated object.

    Also, give BitVector empty and swap functions.

    And, add some simple unittests for BitVector and SmallBitVector.

Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Jan 5 06:29:13 2010 +0000

    inline the 'AddRHS' transformation, simplifying things significantly.
    Eliminate the 'AddMaskingAnd' transformation, it is redundant with this
    more general code right below it:
      // A+B --> A|B iff A and B have no bits set in common.

Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Jan 5 06:24:06 2010 +0000

    remove massive over-genality manifested as a big template
    that got instantiated.  There is no reason for instcombine
    to try this hard for simple associative optimizations.  Next
    up, eliminate the template completely.

commit 39d140d93435c1d47305d0b1c3b8db7b222b6222
Author: Dan Gohman <gohman@apple.com>
Date:   Tue Jan 5 01:24:18 2010 +0000

    Change SelectCode's argument from SDValue to SDNode *, to make it more
    clear what information these functions are actually using.

    This is also a micro-optimization, as passing a SDNode * around is
    simpler than passing a { SDNode *, int } by value or reference.

    Remove dead debug info intrinsics.
     Intrinsic::dbg_stoppoint
     Intrinsic::dbg_region_start
     Intrinsic::dbg_region_end
     Intrinsic::dbg_func_start
    AutoUpgrade simply ignores these intrinsics now.

    Truncate GEP indexes larger than the pointer size down to pointer size
    when doing this transform if the GEP is not inbounds.  No testcase because
    it is very difficult to trigger this: instcombine already canonicalizes
    GEP indices to pointer size, so it relies specific permutations of the
    instcombine worklist.

    Thanks to Duncan for pointing this possible problem out.

    generalize the previous transformation to handle indexing into
    arrays of structs and other arrays, so long as all the subsequent
    indexes are constants.  This triggers frequently for stuff like:

    @divisions = internal constant [29 x [2 x i32]] [[2 x i32] zeroinitializer, [2 x i32] [i32 0, i32 1], [2 x i32] [i32 0, i32 2], [2 x i32] [i32 0, i32 1], [2 x i32] zeroinitializer, [2 x i32] [i32 0, i32 1], [2 x i32] [i32 0, i32 1], [2 x i32] [i32 0, i32 2], [2 x i32] [i32 0, i32 2], [2 x i32] zeroinitializer, [2 x i32] zeroinitializer, [2 x i32] zeroinitializer, [2 x i32] [i32 0, i32 2], [2 x i32] [i32 0, i32 1], [2 x i32] zeroinitializer, [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 1], [2 x i32] [i32 1, i32 1], [2 x i32] [i32 1, i32 2], [2 x i32] [i32 1, i32 1], [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 2], [2 x i32] [i32 1, i32 2], [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 1], [2 x i32] [i32 1, i32 2], [2 x i32] [i32 1, i32 2]], align 32 ; <[29 x [2 x i32]]*> [#uses=50]

    	  %623 = getelementptr inbounds [29 x [2 x i32]]* @divisions, i64 0, i64 %619, i64 0 ; <i32*> [#uses=1]
    	   %684 = icmp eq i32 %683, 999

    also for the "my_defs" table in 'gs', etc.

    teach instcombine to optimize idioms like A[i]&42 == 0.  This
    occurs in 403.gcc in mode_mask_array, in safe-ctype.c (which
    is copied in multiple apps) in _sch_istable, etc.

    git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92427 91177308-0d34-0410-b5e6-96231b3b80d8

commit f0fc16e3f995888e1452b115a14a23cc49025ac4
Author: Chris Lattner <sabre@nondot.org>

    Teach the table lookup optimization to generate range compares
    when a consequtive sequence of elements all satisfies the
    predicate.  Like the double compare case, this generates better
    code than the magic constant case and generalizes to more than
    32/64 element array lookups.

    Here are some examples where it triggers.  From 403.gcc, most
    accesses to the rtx_class array are handled, e.g.:

    @rtx_class = constant [153 x i8] c"xxxxxmmmmmmmmxxxxxxxxxxxxmxxxxxxiiixxxxxxxxxxxxxxxxxxxooxooooooxxoooooox3x2c21c2222ccc122222ccccaaaaaa<<<<<<<<<<<<<<<<<<111111111111bbooxxxxxxxxxxcc2211x", align 32 ; <[153 x i8]*> [#uses=547]
       %142 = icmp eq i8 %141, 105
    @rtx_class = constant [153 x i8] c"xxxxxmmmmmmmmxxxxxxxxxxxxmxxxxxxiiixxxxxxxxxxxxxxxxxxxooxooooooxxoooooox3x2c21c2222ccc122222ccccaaaaaa<<<<<<<<<<<<<<<<<<111111111111bbooxxxxxxxxxxcc2211x", align 32 ; <[153 x i8]*> [#uses=543]
    	   %165 = icmp eq i8 %164, 60

    Also, most of the 59-element arrays (mode_class/rid_to_yy, etc)
    optimized before are actually range compares.  This lets 32-bit
    machines optimize them.

    400.perlbmk has stuff like this:

    400.perlbmk: PL_regkind, even for 32-bit:
    @PL_regkind = constant [62 x i8] c"\00\00\02\02\02\06\06\06\06\09\09\0B\0B\0D\0E\0E\0E\11\12\12\14\14\16\16\18\18\1A\1A\1C\1C\1E\1F !!!$$&'((((,-.///88886789:;8$", align 32 ; <[62 x i8]*> [#uses=4]
    	   %811 = icmp ne i8 %810, 33

    @PL_utf8skip = constant [256 x i8] c"\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\03\03\03\03\03\03\03\03\03\03\03\03\03\03\03\03\04\04\04\04\04\04\04\04\05\05\05\05\06\06\07\0D", align 32 ; <[256 x i8]*> [#uses=94]
    	   %12 = icmp ult i8 %10, 2

    Generalize the previous xform to handle cases where exactly
    two elements match or don't match with two comparisons.  For
    example, the testcase compiles into:

    define i1 @test5(i32 %X) {
      %1 = icmp eq i32 %X, 2                          ; <i1> [#uses=1]
      %2 = icmp eq i32 %X, 7                          ; <i1> [#uses=1]
      %R = or i1 %1, %2                               ; <i1> [#uses=1]
      ret i1 %R
    }

    This generalizes the previous xforms when the array is larger than
    64 elements (and this case matches) and generates better code for
    cases where it overlaps with the magic bitshift case.

    This generalizes more cases than you might expect.  For example,
    400.perlbmk has:

    @PL_utf8skip = constant [256 x i8] c"\01\01\01\...
    %15 = icmp ult i8 %7, 7

    403.gcc has:
    @rid_to_yy = internal constant [114 x i16] [i16 259, i16 260, ...
    %18 = icmp eq i16 %16, 295

    and xalancbmk has a bunch of examples, such as
    _ZN11xercesc_2_5L15gCombiningCharsE and _ZN11xercesc_2_5L10gBaseCharsE.

    enhance the compare/load/index optimization to work on *any* load
    from a global with 32/64 elements or less (depending on whether
    i64 is native on the target), generating a bitshift idiom to
    determine the result.  For example, on test4 we produce:

    define i1 @test4(i32 %X) {
      %1 = lshr i32 933, %X                           ; <i32> [#uses=1]
      %2 = and i32 %1, 1                              ; <i32> [#uses=1]
      %R = icmp ne i32 %2, 0                          ; <i1> [#uses=1]
      ret i1 %R
    }

    This triggers in a number of interesting cases, for example, here's an
    fp case:
    @A.3255 = internal constant [4 x double] [double 4.100000e+00, double -3.900000e+00, double -1.000000e+00, double 1.000000e+00], align 32 ; <[4 x double]*> [#uses=7]
    ...
    	   %7 = fcmp olt double %3, 0.000000e+00

    In this case we make the slen2_tab global dead, which is nice:
    @slen2_tab = internal constant [16 x i32] [i32 0, i32 1, i32 2, i32 3, i32 0, i32 1, i32 2, i32 3, i32 1, i32 2, i32 3, i32 1, i32 2, i32 3, i32 2, i32 3], align 32 ; <[16 x i32]*> [#uses=1]
    ...
    	   %204 = icmp eq i32 %46, 0

    Perl has a bunch of these, also on the 'Perl_regkind' array:
    @Perl_yygindex = internal constant [51 x i16] [i16 0, i16 0, i16 0, i16 0, i16 374, i16 351, i16 0, i16 -12, i16 0, i16 946, i16 413, i16 -83, i16 0, i16 0, i16 0, i16 -311, i16 -13, i16 4007, i16 2893, i16 0, i16 0, i16 0, i16 0, i16 0, i16 372, i16 -8, i16 0, i16 0, i16 246, i16 -131, i16 43, i16 86, i16 208, i16 -45, i16 -169, i16 987, i16 0, i16 0, i16 0, i16 0, i16 308, i16 0, i16 -271, i16 0, i16 0, i16 0, i16 0, i16 0, i16 0, i16 0, i16 0], align 32 ; <[51 x i16]*> [#uses=1]
    ...
      %1364 = icmp eq i16 %1361, 0

    186.crafty really likes this on 64-bit machines, because it triggers on a bunch of globals like this:
    @white_outpost = internal constant [64 x i8] c"\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\02\02\00\00\00\00\00\04\05\05\04\00\00\00\00\03\06\06\03\00\00\00\00\00\01\01\00\00\00\00\00\00\00\00\00\00\00", align 32 ; <[64 x i8]*> [#uses=2]

    However the big winner is 403.gcc, which triggers hundreds of times, eliminating all the accesses to the 57-element arrays 'mode_class', mode_unit_size, mode_bitsize, regclass_map, etc.

    go 64-bit machines :)

    Teach instcombine to fold compares of loads from constant
    arrays with variable indices into a comparison of the index
    with a constant.  The most common occurrence of this that
    I see by far is stuff like:

    if ("foobar"[i] == '\0') ...

    which we compile into: if (i == 6), saving a load and
    materialization of the global address.  This also exposes
    loop trip count information to later passes in many cases.

    This triggers hundreds of times in xalancbmk, which is where I first
    noticed it, but it also triggers in many other apps.  Here are a few
    interesting ones from various apps:

    @must_be_connected_without = internal constant [8 x i8*] [i8* getelementptr inbounds ([3 x i8]* @.str64320, i64 0, i64 0), i8* getelementptr inbounds ([3 x i8]* @.str27283, i64 0, i64 0), i8* getelementptr inbounds ([4 x i8]* @.str71327, i64 0, i64 0), i8* getelementptr inbounds ([4 x i8]* @.str72328, i64 0, i64 0), i8* getelementptr inbounds ([3 x i8]* @.str18274, i64 0, i64 0), i8* getelementptr inbounds ([6 x i8]* @.str11267, i64 0, i64 0), i8* getelementptr inbounds ([3 x i8]* @.str32288, i64 0, i64 0), i8* null], align 32 ; <[8 x i8*]*> [#uses=2]
      %scevgep.i = getelementptr [8 x i8*]* @must_be_connected_without, i64 0, i64 %indvar.i ; <i8**> [#uses=1]
      %17 = load ...

    remove the instcombine transformations that are inserting nasty
    pointer to int casts that confuse later optimizations.  See PR3351
    for details.

    This improves but doesn't complete fix 483.xalancbmk because llvm-gcc
    does this xform in GCC's "fold" routine as well.  Clang++ will do
    better I guess.

    so that instcombine can stop doing this for pointers.  This is part of PR3351,
    which is a case where instcombine doing this for pointers (inserting ptrtoint)
    is pessimizing code.

    Teach codegen to lower llvm.powi to an efficient (but not optimal)
    multiply sequence when the power is a constant integer.  Before, our
    codegen for std::pow(.., int) always turned into a libcall, which was
    really inefficient.

    This should also make many gfortran programs happier I'd imagine.

    When factoring multiply expressions across adds, factor both
    positive and negative forms of constants together.  This
    allows us to compile:

    int foo(int x, int y) {
        return (x-y) + (x-y) + (x-y);
    }

    into:

    _foo:                                                       ## @foo
    	subl	%esi, %edi
    	leal	(%rdi,%rdi,2), %eax
    	ret

    instead of (where the 3 and -3 were not factored):

    _foo:
            imull   $-3, 8(%esp), %ecx
            imull   $3, 4(%esp), %eax
            addl    %ecx, %eax
            ret

    this started out as:
        movl    12(%ebp), %ecx
        imull   $3, 8(%ebp), %eax
        subl    %ecx, %eax
        subl    %ecx, %eax
        subl    %ecx, %eax
        ret

    This comes from PR5359.

    reuse negates where possible instead of always creating them from scratch.
    This allows us to optimize test12 into:

    }

    instead of:

    Optimize MDNode to coallocate the operand list immediately
    after the MDNode in memory.  This eliminates the operands
    pointer and saves a new[] per node.

    Note that the code in DIDerivedType::replaceAllUsesWith is wrong
    and quite scary.  A MDNode should not be RAUW'd with something
    else: this changes all uses of the mdnode, which may not be debug
    info related!  Debug info should use something non-mdnode for
    declarations.

    add a layer of accessors around the Value::SubClassData member, and use
    a convention (shadowing the setter with private forwarding function) to
    prevent subclasses from accidentally using it.

    This exposed some bogosity in ConstantExprs, which was propaging the

    getWithOperands/getWithOperandReplaced methods.

Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Dec 28 23:41:32 2009 +0000

    This is a major cleanup of the instruction metadata interfaces that
    I asked Devang to do back on Sep 27.  Instead of going through the
    MetadataContext class with methods like getMD() and getMDs(), just
    ask the instruction directly for its metadata with getMetadata()
    and getAllMetadata().

    This includes a variety of other fixes and improvements: previously
    all Value*'s were bloated because the HasMetadata bit was thrown into
    value, adding a 9th bit to a byte.  Now this is properly sunk down to
    the Instruction class (the only place where it makes sense) and it
    will be folded away somewhere soon.

    This also fixes some confusion in getMDs and its clients about
    whether the returned list is indexed by the MDID or densely packed.
    This is now returned sorted and densely packed and the comments make
    this clear.

    This introduces a number of fixme's which I'll follow up on.

    Revise scalar replacement to be more flexible about handle bitcasts and GEPs.
    While scanning through the uses of an alloca, keep track of the current offset
    relative to the start of the alloca, and check memory references to see if
    the offset & size correspond to a component within the alloca.  This has the
    nice benefit of unifying much of the code from isSafeUseOfAllocation,
    isSafeElementUse, and isSafeUseOfBitCastedAllocation.  The code to rewrite
    the uses of a promoted alloca, after it is determined to be safe, is
    reorganized in the same way.

    Also, when rewriting GEP instructions, mark them as "in-bounds" since all the
    indices are known to be safe.

    Don't try to move a MBB into the fall-through position if it's a landing pad or
    branches only to a landing pad. Without this check, the compiler would go into
    an infinite loop because the branch to a landing pad is an "abnormal" edge which
    wasn't being taken into account.

    This is the meat of that fix:

      if (!PrevBB.canFallThrough() && !MBB->BranchesToLandingPad(MBB)) {

    The other stuff is simplification of the "branches to a landing pad" code.

    Simplify this class by removing the result cache.

    This change removes the DefaultConstructible
    and CopyAssignable constraints on the template
    parameter T (the first one).

    The second template parameter (R) is defaulted to be
    identical to the first and controls the result type.
    By specifying it to be (const T&) additionally the
    CopyConstructible constraint on T can be removed.

    This allows to use StringSwitch e.g. for llvm::Constant
    instances.

    Regarding the other review feedback regarding performance
    because of taking pointers, this class should be completely
    optimizable like before, since all methods are inline and
    the pointer dereferencing and result value caching should be
    possible behind the scenes by the "as-if" rule.

    A machine basic block may end in an unconditional branch, however it may have
    more than one successor. Normally, these extra successors are dead. However,
    some of them may branch to exception handling landing pads. If we remove those
    successors, then the landing pads could go away if all predecessors to it are
    removed. Before, it was checking if the direct successor was the landing
    pad. But it could be the result of jumping through multiple basic blocks to get
    to it. If we were to only check for the existence of an EH_LABEL in the basic
    block and not remove successors if it's in there, then it could stop actually
    dead basic blocks from being removed.

    Also attempt trivial coalescing for live intervals that end in a copy.

    The coalescer is supposed to clean these up, but when setting up parameters
    for a function call, there may be copies to physregs. If the defining
    instruction has been LICM'ed far away, the coalescer won't touch it.

    The register allocation hint does not always work - when the register
    allocator is backtracking, it clears the hints.

    This patch is more conservative than r90502, and does not break
    483.xalancbmk/i686. It still breaks the PowerPC bootstrap, so it is disabled
    by default, and can be enabled with the -trivial-coalesce-ends option.

    Comparing std::string with NULL is a bad idea, so just check whether its empty.

    This code was crashing always with oprofile enabled, since it tried to create a StringRef
    out of NULL, which run strlen on NULL.

    Fix PR5744, a case where we were getting the pointer size instead of the
    value size.  This only manifested when memdep inprecisely returns clobber,
    which is do to a caching issue in the PR5744 testcase.  We can 'efficiently
    emulate' this by using '-no-aa'

    Add a minor optimization: if we haven't changed the operands of an
    add, there is no need to scan the world to find the same add again.
    This invalidates the previous testcase, which wasn't wonderful anyway,
    because it needed a run of instcombine to permute the use-lists in
    just the right way to before GVN was run (so it was really fragile).
    Not a big loss.

    Added a new "splitting" spiller.

    When a call is placed to spill an interval this spiller will first try to
    break the interval up into its component values. Single value intervals and
    intervals which have already been split (or are the result of previous splits)
    are spilled by the default spiller.

    Splitting intervals as described above may improve the performance of generated
    code in some circumstances. This work is experimental however, and it still
    miscompiles many benchmarks. It's not recommended for general use yet.

    Switch GVN and memdep to use PHITransAddr, which correctly handles
    phi translation of complex expressions like &A[i+1].  This has the
    following benefits:

    1. The phi translation logic is all contained in its own class with
       a strong interface and verification that it is self consistent.

    2. The logic is more correct than before.  Previously, if intermediate
       expressions got PHI translated, we'd miss the update and scan for
       the wrong pointers in predecessor blocks.  @phi_trans2 is a testcase
       for this.

    3. We have a lot less code in memdep.

    We can handle phi translation across blocks of things like @phi_trans3,
    which is pretty insane :).

    This patch should fix the miscompiles of 255.vortex, and I tested it
    with a bootstrap of llvm-gcc, llvm-test and dejagnu of course.

    Put a threshold on the number of users PointerMayBeCaptured
    examines; fall back to a conservative answer if there are
    more. This works around some several compile time problems
    resulting from BasicAliasAnalysis calling PointerMayBeCaptured.

    The value has been chosen arbitrarily.

    This fixes rdar://7438917 and may partially address PR5708.

    Introduce the "@llvm.dbg.value" debug intrinsic.

    The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value.

    An example:
      call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2)
    Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0.

    Also attempt trivial coalescing for live intervals that end in a copy.

    The coalescer is supposed to clean these up, but when setting up parameters
    for a function call, there may be copies to physregs. If the defining
    instruction has been LICM'ed far away, the coalescer won't touch it.

    The register allocation hint does not always work - when the register
    allocator is backtracking, it clears the hints.

    This patch takes care of a few more cases that r90163 missed.

    Fix ExpandShiftWithUnknownAmountBit, which was completely bogus.
    Pointed out by Javier Martinez (who also provided a patch).  Since
    this logic is not used on (for example) x86, I guess nobody noticed.
    Tested by generating SHL, SRL, SRA on various choices of i64 for all
    possible shift amounts, and comparing with gcc.  Since I did this on
    x86-32, I had to force the use of ExpandShiftWithUnknownAmountBit.
    What I'm saying here is that I don't have a testcase I can add to the
    repository.

    This initial code is meant to convert TargetData to use an AbstractTypesUser so
    that it doesn't have dangling pointers when abstract types are resolved. This
    modifies it somewhat to address comments: making the "StructLayoutMap" an
    anonymous structure, calling "removeAbstractTypeUser" when appropriate, and
    adding asserts where helpful.

    Fix PR5391: support early clobber physical register def tied with a use (ewwww)
    - A valno should be set HasRedefByEC if there is an early clobber def in the middle of its live ranges. It should not be set if the def of the valno is defined by an early clobber.
    - If a physical register def is tied to an use and it's an early clobber, it just means the HasRedefByEC is set since it's still one continuous live range.
    - Add a couple of missing checks for HasRedefByEC in the coalescer. In general, it should not coalesce a vr with a physical register if the physical register has a early clobber def somewhere. This is overly conservative but that's the price for using such a nasty inline asm "feature".

    Use CFG connectedness as a secondary sort key when deciding the order of copy coalescing.

    This means that well connected blocks are copy coalesced before the less connected blocks. Connected blocks are more difficult to
    coalesce because intervals are more complicated, so handling them first gives a greater chance of success.

    New virtual registers created for spill intervals should inherit allocation hints from the original register.

    This helps us avoid silly copies when rematting values that are copied to a physical register:

    leaq	_.str44(%rip), %rcx
    movq	%rcx, %rsi
    call	_strcmp

    becomes:

    leaq	_.str44(%rip), %rsi
    call	_strcmp

    The coalescer will not touch the movq because that would tie down the physical register.

    branches even when optimizing for code size.  Unless we find evidence to the
    contrary in the future, the special treatment for indirect branches does not
    have a significant effect on code size, and performance still matters with -Os.

    Remove isProfitableToDuplicateIndirectBranch target hook.  It is profitable
    for all the processors where I have tried it, and even when it might not help
    performance, the cost is quite low.  The opportunities for duplicating
    indirect branches are limited by other factors so code size does not change
    much due to tail duplicating indirect branches aggressively.

    Only print edgeSourceLabels if they are not empty

    Graphviz can layout the graphs better if a node does not contain source
    ports. Therefore only print the ports if the source ports are useful,
    that means are not labeled with the empty string "".
    This patch also simplifies graphs without any edgeSourceLabels e.g. the
    dominance trees.

    Commit r90099 made LLVM simplify one of these constant expressions a little
    more. Update the syntax we're checking for and filecheckize it too.

    This will fix the selfhost buildbots but will 'break' the others (sigh) because
    they're still linked against older LLVM which is emitting less optimized IR.

    Fix a really nasty caching bug I introduced in memdep.  An entry
    was being added to the Result vector, but not being put in the
    cache.  This means that if the cache was reused wholesale for a
    later query that it would be missing this entry and we'd do an
    incorrect load elimination.

    Unfortunately, it's not really possible to write a useful
    testcase for this, but this unbreaks 255.vortex.

    Enhance InsertPHITranslatedPointer to be able to return a list of newly
    inserted instructions.  No functionality change until someone starts using it.

    implement a FIXME: limit the depth that DecomposeGEPExpression goes the same
    way that getUnderlyingObject does it.

    This fixes the 'DecomposeGEPExpression and getUnderlyingObject disagree!'
    assertion on sqlite3.

    enable code to handle un-phi-translatable cases more aggressively:
    if we don't have an address expression available in a predecessor,
    then model this as the value being clobbered at the end of the pred
    block instead of being modeled as a complete phi translation failure.
    This is important for PRE of loads because we want to see that the
    load is available in all but this predecessor, and complete phi
    translation failure results in not getting any information about
    predecessors.

    This doesn't do anything until I renable code insertion since PRE
    now sees that it is available in all but one predecessors, but can't
    insert the addressing in the predecessor that is missing it to
    eliminate the redundancy.

    add support for recursive phi translation and phi
    translation of add with immediate.  This allows us
    to optimize this function:

    void test(int N, double* G) {
      long j;
      G[1] = 1;
        for (j = 1; j < N - 1; j++)
            G[j+1] = G[j] + G[j+1];
    }

    to only do one load every iteration of the loop.

    fix PR5436 by making the 'simple' case of SRoA not promote out of range
    array indexes.  The "complex" case of SRoA still handles them, and correctly.

    This fixes a weirdness where we'd correctly avoid transforming A[0][42] if
    the 42 was too large, but we'd only do it if it was one gep, not two separate
    ones.

    While this test is testing a problem in the generic part of codegen,
    the problem only shows for msp430 and pic16 which is why it specifies
    them using -march.  But it is wrong to put such tests in CodeGen/Generic,
    since not everyone builds these targets.  Put a copy of the test in each
    of the target test directories.

    Fix PR5471 by removing an instcombine xform.  Some pieces of the code
    generates store to undef and some generates store to null as the idiom
    for undefined behavior.  Since simplifycfg zaps both, don't remove the
    undefined behavior in instcombine.

    @test9 is a testcase for r89958.  Before 89958, we misanalyzed the
    first expression as P+4+4*i which we considered to possibly alias
    P+4*j.  Now we correctly analyze the former one as P+1+4*i.

    @test10 is a sanity test that verfies that we know that P+4+4*i != P+4*i.

    Teach basicaa that x|c == x+c when the c bits of x are clear.  This
    allows us to compile the example in readme.txt into:

    LBB1_1:                                                     ## %bb

    	addq	$16, %rax
    	cmpq	$4000, %rax
    	jne	LBB1_1

    instead of:

    LBB1_1:
    	movl	(%rdx,%rax), %ecx
    	imull	4(%rdx,%rax), %ecx
    	movl	%ecx, 8(%rdx,%rax)

    	addq	$16, %rax
    	cmpq	$4000, %rax
    	jne	LBB1_1

    GCC (4.2) doesn't seem to be able to eliminate the loads in this
    testcase either, it generates:

    L2:

    	imull	4(%rdx), %eax

    Change the other half of aliasGEP (which handles GEP differencing) to use DecomposeGEPExpression.  This dramatically simplifies and shrinks the code by eliminating the horrible CheckGEPInstructions method, fixes a miscompilation (@test3) and makes the code more aggressive.  In particular, we now handle the @test4 case, which is reduced from the SmallPtrSet constructor.  Missing this caused us to emit a variable length memset instead of a fixed size one.

    Based on the testcase for pr3120, running on my MacPro with Xeon processors,
    it is definitely profitable to tail duplicate indirect branches for x86.

    Refactor target hook for tail duplication as requested by Chris.
    Make tail duplication of indirect branches much more aggressive (for targets
    that indicate that it is profitable), based on further experience with
    this transformation.  I compiled 3 large applications with and without
    this more aggressive tail duplication and measured minimal changes in code
    size.  ("size" on Darwin seems to round the text size up to the nearest
    page boundary, so I can only say that any code size increase was less than
    one 4k page.) Radar 7421267.

    Do not store R31 into the caller's link area on PPC.
    This violates the ABI (that area is "reserved"), and
    while it is safe if all code is generated with current
    compilers, there is some very old code around that uses
    that slot for something else, and breaks if it is stored
    into.  Adjust testcases looking for current behavior.
    I've verified that the stack frame size is right in all
    testcases, whether it changed or not.  7311323.

    Materialize global addresses via movt/movw pair, this is always better
    than doing the same via constpool:
    1. Load from constpool costs 3 cycles on A9, movt/movw pair - just 2.
    2. Load from constpool might stall up to 300 cycles due to cache miss.
    3. Movt/movw does not use load/store unit.
    4. Less constpool entries => better compiler performance.

    This is only enabled on ELF systems, since darwin does not have needed
    relocations (yet).

    * Move stub allocation inside the JITEmitter, instead of exposing a
    way for each TargetJITInfo subclass to allocate its own stubs. This
    means stubs aren't as exactly-sized anymore, but it lets us get rid of
    TargetJITInfo::emitFunctionStubAtAddr(), which lets ARM and PPC
    support the eager JIT, fixing http://llvm.org/PR4816.

    * Rename the JITEmitter's stub creation functions to describe the kind
    of stub they create. So far, all of them create lazy-compilation
    stubs, but they sometimes get used when far-call stubs are needed.
    Fixing http://llvm.org/PR5201 will involve fixing this.

    I forgot to update the prototype for LLVMBuildIntCast when correcting
    the body to not pass the name for the isSigned parameter.  However it
    seems that changing prototypes is a big-no-no, so here I revert the
    previous change and pass "true" for isSigned, meaning this always does
    a signed cast, which was the previous behaviour assuming the name was
    not NULL!  Some other C function needs to be introduced for the general
    case of signed or unsigned casts.  This hopefully unbreaks the ocaml
    binding.

    FileCheck, PR5239: Try to find the intended match on failures, but looking for a
    good nearby fuzzy match. Frequently the input is nearly correct, and just
    showing the user the a nearby sensible match is enough to diagnose the problem.
     - The "fuzzyness" is pretty simple and arbitrary, but worked on my three test
       cases. If you encounter problems, or places you think FileCheck should have
       guessed but didn't, please add test cases to PR5239.

    For example, previously FileCheck would report this:
    --
    t.cpp:21:55: error: expected string not found in input
    // CHECK: define void @_Z2f25f2_s1([[i64_i64_ty]] %a0)
                                                          ^
    <stdin>:19:30: note: scanning from here
    define void @_Z2f15f1_s1(%1) nounwind {
                                 ^
    <stdin>:19:30: note: with variable "i64_i64_ty" equal to "%0"
    --

    and now it also reports this:
    --
    <stdin>:27:1: note: possible intended match here
    define void @_Z2f25f2_s1(%0) nounwind {
    ^
    --

    which makes it clear that the CHECK just has an extra ' %a0' in it, without
    having to check the input.

    stack-based arguments via the frame pointer.

    Fix pr5470. Tablegen handles template arguments by temporarily setting their
    values, resolving references to them, and then removing the definitions.
    If a template argument is set to an undefined value, we need to resolve
    references to that argument to an explicit undefined value.  The current code
    leaves the reference to the template argument as it is, which causes an
    assertion failure later when the definition of the template argument is
    removed.

    Be more clever about calculating live variables through new basic blocks.

    When splitting a critical edge, the registers live through the edge are:

    - Used in a PHI instruction, or
    - Live out from the predecessor, and
    - Live in to the successor.

    This allows the coalescer to eliminate even more phi joins.

    it may be used in contexts where preheader insertion may have failed due
    to an indirectbr.

    Make LoopSimplify's LoopSimplify::SeparateNestedLoop properly fail in

    The verify() call of CPEIsInRange() isn't right for the assertion check of
    constant pool ranges, as CPEIsInRange() makes conservative assumptions about
    the potential alignment changes from branch adjustments. The verification,
    on the other hand, runs after those branch adjustments are made, so the
    effects on alignment are known and already taken into account. The sanity
    check in verify should check the range directly instead.

    Revert the rule that considers comparisons between two pointers in the
    same object to be a non-capture; Duncan pointed out a way that such
    a comparison could be a capture.

    Make the rule that considers a comparison against null more specific,
    and only consider noalias return values compared against null. This
    still supports test/Transforms/GVN/nonescaping-malloc.ll, and is not
    susceptible to the problem Duncan pointed out with noalias arguments.

    Fix PR5563, an expensive checks failure when running on
    tests/Transforms/InstCombine/shufflemask-undef.ll.  If
    anyone cares, the use of 2*e here (and the equivalent
    all over the place in instcombine) seems wrong, though
    harmless: it should really be twice the length of the
    input vector.  I think shufflevector used to require
    that the mask have the same length as the input, but I
    don't think that's true any more.  I don't care enough
    about vectors to do anything about this...

    When placing constant islands and adjusting for alignment padding, inline
    assembly can confuse things utterly, as it's assumed that instructions in
    inline assembly are 4 bytes wide. For Thumb mode, that's often not true,
    so the calculations for when alignment padding will be present get thrown off,
    ultimately leading to out of range constant pool entry references. Making
    more conservative assumptions that padding may be necessary when inline asm
    is present avoids this situation.

    Place new basic blocks immediately after their predecessor when splitting
    critical edges in PHIElimination.

    This has a huge impact on regalloc performance, and we recover almost all of
    the 10% compile time regression that edge splitting introduced.

    Enable hoisting of loads from constant memory by default. In cases where
    they are lowered to instruction sequences more complex than a simple
    load, such that CodeGen cannot rematerialize them, a reload from a
    spill slot is likely to be cheaper than the complex sequence.

    Add support for spreading register allocation.

    Add a -linearscan-skip-count argument (default to 0) that tells the
    allocator to remember the last N registers it allocated and skip them
    when looking for a register candidate.  This tends to spread out
    register usage and free up post-allocation scheduling at the cost of
    slightly more register pressure.  The primary benefit is the ability
    to backschedule reloads.

    This is turned off by default.

    Workaround PR5482, because all the gcc versions that I had were miscompiling StringRef:
    4.2.4, 4.3.4, 4.4.2.
    The workaround is to use a local min/max implementation that takes an integer
    param, and not a reference to integer param (like std::min does).

    Added a new Spiller implementation which wraps LiveIntervals::addIntervalsForSpills.
    All spiller calls in RegAllocLinearScan now go through the new Spiller interface.
    The "-new-spill-framework" command line option has been removed. To use the trivial in-place spiller you should now pass "-spiller=trivial -rewriter=trivial".
    (Note the trivial spiller/rewriter are only meant to serve as examples of the new in-place modification work. Enabling them will yield terrible, though hopefully functional, code).

    Don't require LiveVariables for PHIElimination. Enable critical edge splitting
    when LiveVariables is available.

    The -split-phi-edges is now gone, and so is the hack to disable it when using
    the local register allocator. The PHIElimination pass no longer has
    LiveVariables as a prerequisite - that is what broke the local allocator.
    Instead we do critical edge splitting when possible - that is when
    LiveVariables is available.

    Add a target hook to allow changing the tail duplication limit based on the
    contents of the block to be duplicated.  Use this for ARM Cortex A8/9 to
    be more aggressive tail duplicating indirect branches, since it makes it
    much more likely that they will be predicted in the branch target buffer.
    Testcase coming soon.

    The llvm-gcc front-end and the pass manager use two separate TargetData objects.
    This is probably not confined to *just* these two things.

    Anyway, the llvm-gcc front-end may look up the structure layout information for
    an abstract type. That information will be stored into a table with the FE's
    TD. Instruction combine can come along and also ask for information on that
    abstract type, but for a separate TD (the one associated with the pass manager).

    After the type is refined, the old structure layout information in the pass
    manager's TD file is out of date. If a new type is allocated in the same space
    as the old-unrefined type, then the structure type information in the pass
    manager's TD file will be wrong, but won't know it.

    Fix this by making the TD's structure type information an abstract type user.

    Remove a special case for tail merging that seems to be both broken and
    unnecessary.  It is broken because the "isIdenticalTo" check should be
    negated.  If that is fixed, this code causes the CodeGen/X86/tail-opts.ll
    test to fail, in the dont_merge_oddly function.  And, I confirmed that the
    regression is real -- the generated code is worse.  As far as I can tell,
    that tail-opts.ll test is checking for what this code is supposed to handle
    and we're doing the right thing anyway.

    1.  Allow SCCIterator to work with GraphT types that are constant.
    2.  Allow SCCIterator to work with inverse graphs.
    3.  Fix an incorrect comment in GraphTraits.h (the type in the comment
    was given as GraphType* when it is actually const GraphType &).

Author: Jeffrey Yasskin <jyasskin@google.com>
Date:   Mon Nov 16 22:41:33 2009 +0000

    Make X86-64 in the Large model always emit 64-bit calls.
    The large code model is documented at
    http://www.x86-64.org/documentation/abi.pdf and says that calls should
    assume their target doesn't live within the 32-bit pc-relative offset
    that fits in the call instruction.

    To do this, we turn off the global-address->target-global-address
    conversion in X86TargetLowering::LowerCall(). The first attempt at
    this broke the lazy JIT because it can separate the movabs(imm->reg)
    from the actual call instruction. The lazy JIT receives the address of
    the movabs as a relocation and needs to record the return address from
    the call; and then when that call happens, it needs to patch the
    movabs with the newly-compiled target. We could thread the call
    instruction into the relocation and record the movabs<->call mapping
    explicitly, but that seems to require at least as much new
    complication in the code generator as this change.

    To fix this, we make lazy functions _always_ go through a call
    stub. You'd think we'd only have to force lazy calls through a stub on
    difficult platforms, but that turns out to break indirect calls
    through a function pointer. The right fix for that is to distinguish
    between calls and address-of operations on uncompiled functions, but
    that's complex enough to leave for someone else to do.

    Another attempt at this defined a new CALL64i pseudo-instruction,
    which expanded to a 2-instruction sequence in the assembly output and
    was special-cased in the X86CodeEmitter's emitInstruction()
    function. That broke indirect calls in the same way as above.

    This patch also removes a hack forcing Darwin to the small code model.
    Without far-call-stubs, the small code model requires things of the
    JITMemoryManager that the DefaultJITMemoryManager can't provide.

    Thanks to echristo for lots of testing!

    Make sure that if anyone passes a name by accident for the isSigned
    parameter of CreateIntCast then they get an error from the compiler
    (or from the linker with a non-gcc compiler).  Another possibility
    is to flip the order of the DestTy and isSigned parameters, since you
    should then get a compiler warning if you try to use a char* for a
    Type*.

    When optimizing for size, don't tail-merge unless it's likely to be a
    code-size win, and not when it's only likely to be code-size neutral,
    such as when only a single instruction would be eliminated and a new
    branch would be required.

    This fixes rdar://7392894.

    Add hasLoadFromStackSlot and hasStoreToStackSlot to return whether a
    machine instruction loads or stores from/to a stack slot.  Unlike
    isLoadFromStackSlot and isStoreFromStackSlot, the instruction may be
    something other than a pure load/store (e.g. it may be an arithmetic
    operation with a memory operand).  This helps AsmPrinter determine when
    to print a spill/reload comment.

    This is only a hint since we may not be able to figure this out in all
    cases.  As such, it should not be relied upon for correctness.

    Implement for X86.  Return false by default for other architectures.

    If there's more than one function operand to a call instruction, be conservative
    and don't assume that the call doesn't throw. It would be nice if there were a
    way to determine which is the callee and which is a parameter. In practice, the
    architecture we care about normally only have one operand for a call instruction
    (x86 and arm).

commit 83cd6cbb1c6ad22198d156c6d43b1158eeca4ee8

    implement a nice little efficiency hack in the inliner.  Since we're now
    running IPSCCP early, and we run functionattrs interlaced with the inliner,
    we often (particularly for small or noop functions) completely propagate
    all of the information about a call to its call site in IPSSCP (making a call
    dead) and functionattrs is smart enough to realize that the function is
    readonly (because it is interlaced with inliner).

    To improve compile time and make the inliner threshold more accurate, realize
    that we don't have to inline dead readonly function calls.  Instead, just
    delete the call.  This happens all the time for C++ codes, here are some
    counters from opt/llvm-ld counting the number of times calls were deleted vs
    inlined on various apps:

    Tramp3d opt:
      5033 inline                - Number of call sites deleted, not inlined
     24596 inline                - Number of functions inlined
    llvm-ld:
      667 inline           - Number of functions deleted because all callers found
      699 inline           - Number of functions inlined

    483.xalancbmk opt:
      8096 inline                - Number of call sites deleted, not inlined
     62528 inline                - Number of functions inlined
    llvm-ld:
       217 inline           - Number of allocas merged together
      2158 inline           - Number of functions inlined

    471.omnetpp:
      331 inline                - Number of call sites deleted, not inlined
     8981 inline                - Number of functions inlined
    llvm-ld:
      171 inline           - Number of functions deleted because all callers found
      629 inline           - Number of functions inlined

    Deleting a call is much faster than inlining it, and is insensitive to the
    size of the callee. :)

    - Teach LSR to avoid changing cmp iv stride if it will create an immediate that
      cannot be folded into target cmp instruction.
    - Avoid a phase ordering issue where early cmp optimization would prevent the
      later count-to-zero optimization.
    - Add missing checks which could cause LSR to reuse stride that does not have
      users.
    - Fix a bug in count-to-zero optimization code which failed to find the pre-inc
      iv's phi node.
    - Remove, tighten, loosen some incorrect checks disable valid transformations.
    - Quite a bit of code clean up.

    instead of typedefs for std::pair. This simplifies the type of

    Add support for tail duplication to BranchFolding, and extend
    tail merging support to handle more cases.
     - Recognize several cases where tail merging is beneficial even when
       the tail size is smaller than the generic threshold.
     - Make use of MachineInstrDesc::isBarrier to help detect
       non-fallthrough blocks.
     - Check for and avoid disrupting fall-through edges in more cases.

commit 409558d2c4f941068e3d00eed5e0242ddeb90fba
Author: Jakob Stoklund Olesen <stoklund@2pi.dk>
Date:   Wed Nov 11 19:31:31 2009 +0000

    Fix liveness calculation when splitting critical edges during PHI elimination.

    - Edges are split before any phis are eliminated, so the code is SSA.

    - Create a proper IR BasicBlock for the split edges.

    - LiveVariables::addNewBlock now has same syntax as
      MachineDominatorTree::addNewBlock. Algorithm calculates predecessor live-out
      set rather than successor live-in set.

    This feature still causes some miscompilations.

    Don't trivially delete unused calls to llvm.invariant.start.  This allows
    llvm.invariant.start to be used without necessarily being paired with a call
    to llvm.invariant.end.  If you run the entire optimization pipeline then such
    calls are in fact deleted (adce does it), but that's actually a good thing since
    we probably do want them to be zapped late in the game.  There should really be
    an integration test that checks that the llvm.invariant.start call lasts long
    enough that all passes that do interesting things with it get to do their stuff
    before it is deleted.  But since no passes do anything interesting with it yet
    this will have to wait for later.

    The TBB and TBH instructions for Thumb2 are really handy for jump tables, but
    can only branch forward. To best take advantage of them, we'd like to adjust
    the basic blocks around a bit when reasonable. This patch puts basics in place
    to do that, with a super-simple algorithm for backwards jump table targets that
    creates a new branch after the jump table which branches backwards. Real
    heuristics for reordering blocks or other modifications rather than inserting
    branches will follow.

    Modify how the prologue encoded the "move" information for the FDE. GCC
    generates a sequence similar to this:

    __Z4funci:
    LFB2:
            mflr r0
    LCFI0:
            stmw r30,-8(r1)
    LCFI1:
            stw r0,8(r1)
    LCFI2:
            stwu r1,-80(r1)
    LCFI3:
            mr r30,r1
    LCFI4:

    where LCFI3 and LCFI4 are used by the FDE to indicate what the FP, LR, and other
    things are. We generated something more like this:

    Leh_func_begin1:
            mflr r0
            stw r31, 20(r1)
            stw r0, 8(r1)
    Llabel1:
            stwu r1, -80(r1)
    Llabel2:
            mr r31, r1

    Note that we are missing the "mr" instruction. This patch makes it more like the
    GCC output.

    make jump threading recursively simplify expressions instead of doing it
    just one level deep.  On the testcase we go from getting this:

    F1:                                               ; preds = %T2
      %F = and i1 true, %cond                         ; <i1> [#uses=1]
      br i1 %F, label %X, label %Y

    to a fully threaded:

    F1:                                               ; preds = %T2
      br label %Y

    instructions on doug's strswitch testcase.

    Fix DenseMap iterator constness.

    This patch forbids implicit conversion of DenseMap::const_iterator to
    DenseMap::iterator which was possible because DenseMapIterator inherited
    (publicly) from DenseMapConstIterator. Conversion the other way around is now
    allowed as one may expect.

    The template DenseMapConstIterator is removed and the template parameter
    IsConst which specifies whether the iterator is constant is added to
    DenseMapIterator.

    Actually IsConst parameter is not necessary since the constness can be
    determined from KeyT but this is not relevant to the fix and can be addressed
    later.

    Patch by Victor Zverovich!

    Generalize LCSSA to handle loops with exits with predecessors outside
    the loop. This is needed because with indirectbr it may not be possible
    for LoopSimplify to guarantee that all loop exit predecessors are
    inside the loop. This fixes PR5437.

    LCCSA no longer actually requires LoopSimplify form, but for now it
    must still have the dependency because the PassManager doesn't know
    how to schedule LoopSimplify otherwise.

    Revert my previous patch to ABCD and fix things the right way.  There are two problems addressed
    here:

    1) We need to avoid processing sigma nodes as phi nodes for constraint generation.
    2) We need to generate constraints for comparisons against constants properly.

    This includes our first working ABCD test!

    Fix an issue where the ordering of blocks within a function could lead to different constraint
    graphs being produced.  The cause was that we were incorrectly marking sigma instructions as
    processed after handling the sigma-specific constraints for them, potentially neglecting to
    process them as normal instructions as well.

    Unfortunately, the testcase that inspired this still doesn't work because of a bug in the solver,
    which is next on the list to debug.

    Teach an instcombine to not pull trunc instructions through PHI nodes
    when both the source and dest are illegal types, since it would cause
    the phi to grow (for example, we shouldn't transform test14b's phi to
    a phi on i320).  This fixes an infinite loop on i686 bootstrap with
    phi slicing turned on, so turn it back on.

    add the ability for TargetData to return information about legal integer
    datatypes on a given CPU.  This is intended to allow instcombine and other
    transformations to avoid converting big sequences of operations to an
    inconvenient width, and will help clean up after SRoA.  See also "Adding
    legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451.

    Make the need-stub variables accurate and consistent.  In the case of
    MachineRelocations, "stub" always refers to a far-call stub or a
    load-a-faraway-global stub, so this patch adds "Far" to the term. (Other stubs
    are used for lazy compilation and dlsym address replacement.) The variable was
    also inconsistent between the positive and negative sense, and the positive
    sense ("NeedStub") was more demanding than is accurate (since a nearby-enough
    function can be called directly even if the platform often requires a stub).
    Since the negative sense causes double-negatives, I switched to
    "MayNeedFarStub" globally.

      except it doesn't care if the definitions' virtual registers differ. This is

    - Teach Thumb2InstrInfo::isIdentical() to check two t2LDRpci_pic are identical.
      Since pc relative constantpool entries are always different, this requires it
      it check if the values can actually the same.

    My previous patch (r84124) for setting the encoding bits 4 and 7 of DPSoRegFrm
    was wrong and too aggressive in the sense that DPSoRegFrm includes both constant
    shifts (with Inst{4} = 0) and register controlled shifts (with Inst{4} = 1 and
    Inst{7} = 0).  The 'rr' fragment of the multiclass definitions actually means
    register/register with no shift, see A8-11.

    Re-commit r86077 now that r86290 fixes the 179.art and 175.vpr ARM regressions.

    Here is the original commit message:

    This commit updates malloc optimizations to operate on malloc calls that have constant int size arguments.

    Update CreateMalloc so that its callers specify the size to allocate:
    MallocInst-autoupgrade users use non-TargetData-computed allocation sizes.
    Optimization uses use TargetData to compute the allocation size.

    Now that malloc calls can have constant sizes, update isArrayMallocHelper() to use TargetData to determine the size of the malloced type and the size of malloced arrays.
    Extend getMallocType() to support malloc calls that have non-bitcast uses.

    Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses.  The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly.

    Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses.  The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use.

    Update OptimizeOnceStoredGlobal() to not care about the malloc calls' bitcast use.

    Update all globalopt malloc tests to not rely on autoupgraded-MallocInsts, but instead use explicit malloc calls with correct allocation sizes.

    - Add pseudo instructions tLDRpci_pic and t2LDRpci_pic which does a pc-relative
      load of a GV from constantpool and then add pc. It allows the code sequence to
      be rematerializable so it would be hoisted by machine licm.
    - Add a late pass to break these pseudo instructions into a number of real
      instructions. Also move the code in Thumb2 IT pass that breaks up t2MOVi32imm
      to this pass. This is done before post regalloc scheduling to allow the
      scheduler to proper schedule these instructions. It also allow them to be
      if-converted and shrunk by later passes.

    Print VMOV (immediate) operands as hexadecimal values.  Apple's assembler
    will not accept negative values for these.  LLVM's default operand printing
    sign extends values, so that valid unsigned values appear as negative
    immediates.  Print all VMOV immediate operands as hex values to resolve this.

    Extend jump threading to support much more general threading
    predicates.  This allows us to jump thread things like:

    _ZN12StringSwitchI5ColorE4CaseILj7EEERS1_RAT__KcRKS0_.exit119:
      %tmp1.i24166 = phi i8 [ 1, %bb5.i117 ], [ %tmp1.i24165, %_Z....exit ], [ %tmp1.i24165, %bb4.i114 ]
      %toBoolnot.i87 = icmp eq i8 %tmp1.i24166, 0     ; <i1> [#uses=1]
      %tmp4.i90 = icmp eq i32 %tmp2.i, 6              ; <i1> [#uses=1]
      %or.cond173 = and i1 %toBoolnot.i87, %tmp4.i90  ; <i1> [#uses=1]
      br i1 %or.cond173, label %bb4.i96, label %_ZN12...

    Where it is "obvious" that when coming from %bb5.i117 that the 'and' is always
    false.  This triggers a surprisingly high number of times in the testsuite,
    and gets us closer to generating good code for doug's strswitch testcase.

    This also make a bunch of other code in jump threading redundant, I'll rip
    out in the next patch.  This survived an enable-checking llvm-gcc bootstrap.

    Add an assertion to catch indirectbr in SplitBlockPredecessors. This
    makes several optimization passes abort in cases where they're currently
    silently miscompiling code.

    Remove the indirectbr assertion from SplitEdge. Indirectbr is only
    a problem for critical edges, and SplitEdge defers to SplitCriticalEdge
    to handle those, and SplitCriticalEdge has its own assertion for
    indirectbr.

    Update CreateMalloc so that its callers specify the size to allocate:
    MallocInst-autoupgrade users use non-TargetData-computed allocation sizes.
    Optimization uses use TargetData to compute the allocation size.

    Now that malloc calls can have constant sizes, update isArrayMallocHelper() to use TargetData to determine the size of the malloced type and the size of malloced arrays.
    Extend getMallocType() to support malloc calls that have non-bitcast uses.

    Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses.  The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly.

    Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses.  The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use.

    Update OptimizeOnceStoredGlobal() to not care about the malloc calls' bitcast use.

    Update all globalopt malloc tests to not rely on autoupgraded-MallocInsts, but instead use explicit malloc calls with correct allocation sizes.

    to EmitGEPOffset.

    Implement some new transforms for optimizing
    subtracts of two pointer to ints into the same vector.  This happens
    for C++ iterator idioms for example, stringmap takes a const char*
    that points to the start and end of a string.  Once inlined, we want
    the pointer difference to turn back into a length.

    The Indexes Patch.

    This introduces a new pass, SlotIndexes, which is responsible for numbering
    instructions for register allocation (and other clients). SlotIndexes numbering
    is designed to match the existing scheme, so this patch should not cause any
    changes in the generated code.

    For consistency, and to avoid naming confusion, LiveIndex has been renamed
    SlotIndex.

    The processImplicitDefs method of the LiveIntervals analysis has been moved
    into its own pass so that it can be run prior to SlotIndexes. This was
    necessary to match the existing numbering scheme.

    Fix branch folding bug for indirect branches: for a block containing only
    an unconditional branch (possibly from tail merging), this code is
    trying to redirect all of its predecessors to go directly to the branch
    target, but that isn't feasible for indirect branches.  The other
    predecessors (that don't end with indirect branches) could theoretically
    still be handled, but that is not easily done right now.

    The AnalyzeBranch interface doesn't currently let us distinguish jump table
    branches from indirect branches, and this code is currently handling
    jump tables.  To avoid punting on address-taken blocks, we would have to give
    up handling jump tables.  That seems like a bad tradeoff.

    Run the functionattrs pass after the inliner, and not before.
    This makes both logical sense (see below) and increases the
    number of functions marked readnone/readonly by about 1-2%
    in practice.  The number of functions marked nocapture goes
    up by about 5-10%.  The reason it makes sense is shown by
    the following example: if you run -functionattrs -inline on
    it, then no attributes are assigned.  But if you instead run
    -inline -functionattrs then @f is marked readnone because the
    simplifications produced by the inliner eliminate the store.

    @x = external global i32

    define void @w(i1 %b) {
            br i1 %b, label %write, label %return
    write:
            store i32 1, i32 *@x
            br label %return
    return:
            ret void
    }

    define void @f() {
            call void @w(i1 0)
            ret void
    }

    Initilize the machine LICM CSE map upon the first time an instruction is hoisted to
    the loop preheader. Add instructions which are already in the preheader block that
    may be common expressions of those that are hoisted out. These does get a few more
    instructions CSE'ed.

    improve IPSCCP to be able to propagate the result of "!mayBeOverridden"
    function to calls of that function, regardless of whether it has local
    linkage or has its address taken.  Not escaping should only affect
    whether we make an aggressive assumption about the arguments to a
    function, not whether we can track the result of it.

    switch the main 'ValueState' map from being an std::map to being
    a DenseMap.  Doing this required being aware of subtle iterator
    invalidation issues, but it provides a big speedup.  In a
    release-asserts build, this sped up optimizing 403.gcc from
    1.34s -> 0.79s (IPSCCP) and 1.11s -> 0.44s (SCCP).

    This commit also conflates in a bunch of general cleanups, sorry.

    fix two strange things in the default passmgr:

    1. we'd run simplifycfg at the very start, even though
    the per function passes have already cleaned this up.

    2. In the main per-function pipeline that is interlaced with inlining
       etc, we would do instcombine, jump threading, simplifycfg *before*
       doing SROA.  SROA is much more likely to expose opportunities for
       these passes than they are for SROA, so move SRoA up earlier.

    also add some comments.

    when merging two loads, make sure to take the min of their alignment,
    not the max.  This didn't matter until the previous patch because
    instcombine would refuse to sink loads with differenting alignments.

    fix a bug noticed by inspection: when instcombine sinks loads through
    phis, it didn't preserve the alignment of the load.  This is a missed
    optimization of the alignment is high and a miscompilation when the
    alignment is low.

    We currently only run ipsccp at LTO time, which is silly.  It subsumes
    ipconstprop and doesn't take much time.  Just run it in its place.

    This adds a testcase for it, which I plan to expand to cover other
    "integration" cases, where we expect the optimizer to be able to
    eliminate various things.  Due to phase order issues we've regressed
    in a number of areas and integration tests are the only way I see to
    prevent this.

    change llvm::MergeBlockIntoPredecessor to not merge two blocks BB1->BB2
    when BB2 has its address taken.  Since it ends up doing BB2->rauw(BB1),
    this can cause the address of the entry block to be taken.  Since it is
    generally undesirable to nuke blocks whose address is taken, even when
    we can, just unconditionally stop this xform.

    Make blockaddress(@func, null) be valid, and make 'deleting a basic
    block with a blockaddress still referring to it' replace the invalid
    blockaddress with a new blockaddress(@func, null) instead of a
    inttoptr(1).

    This changes the bitcode encoding format, and still needs codegen
    support (this should produce a non-zero value, referring to the entry
    block of the function would also be quite reasonable).

    Updates to the ARM target assembler for llvm-mc per review comments from
    Daniel Dunbar.
    - Reordered the fields in the ARMOperand Mem struct to make the struct smaller.
    Making bool's into 1 bit fields and put the MCExpr* fields adjacent to each
    other.
    - Fixed a number of places in ARMAsmParser.cpp so they have doxygen comments.
    - Change the name of ARMAsmParser::ParseRegister() to MaybeParseRegister and
    added the bool ParseWriteBack parameter.
    - Changed ARMAsmParser::ParseMemory() to call MaybeParseRegister().
    - Added ARMAsmParser::ParseMemoryOffsetReg to factor out parsing the offset of a
    memory operand.  And use it for both parsing both preindexed and post indexing
    addressing forms in ARMAsmParser::ParseMemory.
    - Changed the first argument to ParseShift() to a reference.
    - Changed ParseShift() to check for Rrx first and return to reduce nesting.

    Fix MachineLICM to use the correct virtual register class when
    unfolding loads for hoisting.  getOpcodeAfterMemoryUnfold returns the
    opcode of the original operation without the load, not the load
    itself, MachineLICM needs to know the operand index in order to get
    the correct register class. Extend getOpcodeAfterMemoryUnfold to
    return this information.

    In ARMTargetLowering::LowerFormalArguments if the function has 4 or
    more regular arguments we used to set VarArgsFrameIndex using an
    offset of 0, which is only correct if the function has exactly 4
    regular arguments.

    When the function is doing dynamic stack realignment, the spill slot will be
    indexed via the stack pointer, even if a frame pointer is present. Update the
    heuristic to place it nearest the stack pointer in that case, rather than
    nearest the frame pointer.

    add bitcode reader support for blockaddress.  We can now fully
    round trip blockaddress through .ll and .bc files, so add a testcase.

    There are still a bunch of places in the optimizer and other places
    that need to be updated to work with these constructs, but at least
    the basics are in now.

    Previously, all operands to Constant were themselves constant.
    In the new world order, BlockAddress can have a BasicBlock operand.
    This doesn't permute much, because if you have a ConstantExpr (or
    anything more specific than Constant) we still know the operand has
    to be a Constant.

    Update SystemZ to use PSW following the way x86 uses EFLAGS. Besides
    eliminating a use of MVT::Flag, this is needed for an upcoming CodeGen
    change.

    This unfortunately requires SystemZ to switch to the list-burr
    scheduler, in order to handle the physreg defs properly, however
    that's what LLVM has available at this time.

    Record CodeGen optimization level in the BranchFolding pass so that we can
    use it to control tail merging when there is a tradeoff between performance
    and code size.  When there is only 1 instruction in the common tail, we have
    been merging.  That can be good for code size but is a definite loss for
    performance.  Now we will avoid tail merging in that case when the
    optimization level is "Aggressive", i.e., "-O3".  Radar 7338114.

    Since the IfConversion pass invokes BranchFolding, it too needs to know
    the optimization level.  Note that I removed the RegisterPass instantiation
    for IfConversion because it required a default constructor.  If someone
    wants to keep that for some reason, we can add a default constructor with
    a hard-wired optimization level.

    Fix a pretty serious misfeature of the inliner: if it inlines a function
    with multiple return values it inserts a PHI to merge them all together.
    However, if the return values are all the same, it ends up with a pointless
    PHI and this pointless PHI happens to really block SRoA from happening in
    at least a silly C++ example written by Doug, but probably others.  This
    fixes rdar://7339069.

    Automatically do the equivalent of freeMachineCodeForFunction(F) when F is
    being destroyed. This allows users to run global optimizations like globaldce
    even after some functions have been jitted.

    This patch also removes the Function* parameter to
    JITEventListener::NotifyFreeingMachineCode() since it can cause that to be
    called when the Function is partially destroyed. This change will be even more
    helpful later when I think we'll want to allow machine code to actually outlive
    its Function.

    Check in the experimental GEP splitter pass. This pass splits complex
    GEPs (more than one non-zero index) into simple GEPs (at most one
    non-zero index).  In some simple experiments using this it's not
    uncommon to see 3% overall code size wins, because it exposes
    redundancies that can be eliminated, however it's tricky to use
    because instcombine aggressively undoes the work that this pass does.

    When checking whether a def of an aliased register is dead, ask the
    machineinstr whether the aliased register is dead, rather than the original
    register is dead. This allows it to get the correct answer when examining
    an instruction like this:
      CALLpcrel32 <ga:foo>, %AL<imp-def>, %EAX<imp-def,dead>
    where EAX is dead but a subregister of it is still live. This fixes PR5294.

    Make LSR's OptimizeShadowIV ignore induction variables with negative
    strides for now, because it doesn't handle them correctly. This fixes a
    miscompile of SingleSource/Benchmarks/Misc-C++/ray.

    variables into negations of canonical induction variables.

    - Revert some changes from 85044, 85045, and 85047 that broke x86_64 tests and
      bootstrapping. It's not safe to leave identity subreg_to_reg and insert_subreg
      around.
    - Relax register scavenging to allow use of partially "not-live" registers. It's
      common for targets to operate on registers where the top bits are undef. e.g.
      s0 =
      d0 = insert_subreg d0<undef>, s0, 1
      ...
         = d0
      When the insert_subreg is eliminated by the coalescer, the scavenger used to
      complain. The previous fix was to keep to insert_subreg around. But that's
      brittle and it's overly conservative when we want to use the scavenger to
      allocate registers. It's actually legal and desirable for other instructions
      to use the "undef" part of d0. e.g.
      s0 =
      d0 = insert_subreg d0<undef>, s0, 1
      ...
      s1 =
         = s1
         = d0
      We probably need add a "partial-undef" marker on machine operand so the
      machine verifier would not complain.

commit 8e39cf73d44aea2c233909dff6504362a6ccce8e
Author: Chris Lattner <sabre@nondot.org>
Date:   Sun Oct 25 06:15:37 2009 +0000

    Teach FoldBitCast to be able to handle bitcasts from (e.g.) i128 -> <4 x float>.

    This allows us to simplify this:
    union vec2d {
        double e[2];
        double v __attribute__((vector_size(16)));
    };
    typedef union vec2d vec2d;

    static vec2d a={{1,2}}, b={{3,4}};

    vec2d foo () {
        return (vec2d){ .v = a.v + b.v * (vec2d){{5,5}}.v };
    }

    down to:

    define %0 @foo() nounwind ssp {
    entry:
      %mrv5 = insertvalue %0 undef, double 1.600000e+01, 0 ; <%0> [#uses=1]
      %mrv6 = insertvalue %0 %mrv5, double 2.200000e+01, 1 ; <%0> [#uses=1]
      ret %0 %mrv6
    }

    instead of:

    define %0 @foo() nounwind ssp {
    entry:
      %mrv5 = insertvalue %0 undef, double extractelement (<2 x double> fadd (<2 x double> fmul (<2 x double> bitcast (<1 x i128> <i128 85174437667405312423031577302488055808> to <2 x double>), <2 x double> <double 3.000000e+00, double 4.000000e+00>), <2 x double> <double 1.000000e+00, double 2.000000e+00>), i32 0), 0 ; <%0> [#uses=1]
      %mrv6 = insertvalue %0 %mrv5, double extractelement (<2 x double> fadd (<2 x double> fmul (<2 x double> bitcast (<1 x i128> <i128 85174437667405312423031577302488055808> to <2 x double>), <2 x double> <double 3.000000e+00, double 4.000000e+00>), <2 x double> <double 1.000000e+00, double 2.000000e+00>), i32 1), 1 ; <%0> [#uses=1]

    Restrict Thumb1 register allocation to low registers, even for instructions that
    can access the hi regs. Our prologue and epilogue code doesn't know how to
    properly handle save/restore of the hi regs, so things go badly when we alloc

    Fix http://llvm.org/PR4822: allow module deletion after a function has been
    compiled.

    When functions are compiled, they accumulate references in the JITResolver's
    stub maps. This patch removes those references when the functions are
    destroyed.  It's illegal to destroy a Function when any thread may still try to
    call its machine code.

    This patch also updates r83987 to use ValueMap instead of explicit CallbackVHs
    and fixes a couple "do stuff inside assert()" bugs from r84522.

    teach libanalysis to fold int and fp loads from almost arbitrary
    non-type-safe constant initializers.  This sort of thing happens
    quite a bit for 4-byte loads out of string constants, unions,
    bitfields, and an interesting endianness check from sqlite, which
    is something like this:

    const int sqlite3one = 1;
    # define SQLITE_BIGENDIAN    (*(char *)(&sqlite3one)==0)
    # define SQLITE_LITTLEENDIAN (*(char *)(&sqlite3one)==1)
    # define SQLITE_UTF16NATIVE (SQLITE_BIGENDIAN?SQLITE_UTF16BE:SQLITE_UTF16LE)

    all of these macros now constant fold away.

    This implements PR3152 and is based on a patch started by Eli, but heavily
    modified and extended.

    Use 'waitpid' instead of 'wait'.  Basing Program::Wait() on 'wait()' prevents it being correct within a multithreaded context.

    Note: If waitpid() turns out to be non-portable, we can add more autoconf magic, or look into

    Add a ValueMap<ValueOrSubclass*, T> type.  ValueMap<Value*, T> is safe to use
    even when keys get RAUWed and deleted during its lifetime. By default the keys
    act like WeakVHs, but users can pass a third template parameter to configure
    how updates work and whether to do anything beyond updating the map on each
    action.

    It's also possible to automatically acquire a lock around ValueMap updates
    triggered by RAUWs and deletes, to support the ExecutionEngine.

    Revert the main portion of r31856. It was causing BranchFolding
    to break up CFG diamonds by banishing one of the blocks to the end of
    the function, which is bad for code density and branch size.

    This does pessimize MultiSource/Benchmarks/Ptrdist/yacr2, the
    benchmark cited as the reason for the change, however I've examined
    the code and it looks more like a case of gaming a particular
    branch than of being generally applicable.

    Make changes to rev 84292 as requested by Chris Lattner.

    Most changes are cleanup, but there is 1 correctness fix:
    I fixed InstCombine so that the icmp is removed only if the malloc call is removed (which requires explicit removal because the Worklist won't DCE any calls since they can have side-effects).

    Add a pass to overlay pic16 data sections for function frame and automatic
    variables. This pass can be invoked by llvm-ld or opt to traverse over the call graph
    to detect what function frames and their automatic variables can be overlaid.
    Currently this builds an archive , but needs to be changed to a loadable module.

    make GVN work better when TD is not around:

    "In the existing code, if the load and the value to replace it with are
    of different types *and* target data is available, it tries to use the
    target data to coerce the replacement value to the type of the load.
    Otherwise, it skips all effort to handle the type mismatch and just
    feeds the wrongly-typed replacement value to replaceAllUsesWith, which
    triggers an assertion.

    The patch replaces it with an outer if checking for type mismatch, and
    an inner if-else that checks whether target data is available and, if
    not, returns false rather than trying to replace the load."

    Restore LoopUnswitch's block-oriented threshold. LoopUnswitch now checks both
    the estimated code size and the number of blocks when deciding whether to
    do a non-trivial unswitch. This protects it from some very undesirable
    worst-case behavior on large numbers of loop-unswitchable conditions, such
    as in the testcase in PR5259.

    Move the Function*->allocated blocks map from the JITMemoryManager to the
    JITEmitter.

    I'm gradually making Functions auto-remove themselves from the JIT when they're
    destroyed. In this case, the Function needs to be removed from the JITEmitter,
    but the map recording which Functions need to be removed lived behind the
    JITMemoryManager interface, which made things difficult.

    This patch replaces the deallocateMemForFunction(Function*) method with a pair
    of methods deallocateFunctionBody(void *) and deallocateExceptionTable(void *)
    corresponding to the two startFoo/endFoo pairs.

    Make TranslateX86CC return COND_INVALID instead of aborting when it
    encounters an OEQ or UNE comparison, and update its callers to check
    for this return status and recover. This fixes a problem resulting from
    the LowerOperation hooks being called from LegalizeVectorOps, because
    LegalizeVectorOps only lowers vectors, so OEQ and UNE comparisons may
    still be at large. This fixes PR5092.

    Fix PR4313: IPSCCP was not setting the lattice value for the invoke instruction
    when the invoke had multiple return values: it set the lattice value only on the
    extractvalue.
    This caused the invoke's lattice value to remain the default (undefined), and
    later propagated to extractvalue's operand, which incorrectly introduces
    undefined behavior.

    remove strings from instructions who are never asmprinted.
    All of these "subreg32" modifier instructions are handled
    explicitly by the MCInst lowering phase.  If they got to
    the asmprinter, they would explode.  They should eventually
    be replace with correct use of subregs.

    Clean up the JITResolver stub/callsite<->function maps.

    The JITResolver maps Functions to their canonical stubs and all callsites for
    lazily-compiled functions to their target Functions. To make Function
    destruction work, I'm going to need to remove all callsites on destruction, so
    this patch also adds the reverse mapping for that.

    There was an incorrect assumption in here that the only stub for a function
    would be the one caused by needing to lazily compile it, while x86-64 far calls
    and dlsym-stubs could also cause such stubs, but I didn't look for a test case
    that the assumption broke.

    This also adds DenseMapInfo<AssertingVH> so I can use DenseMaps instead of
    std::maps.

    -Revert parts of 84326 and 84411. Distinquishing between fixed and non-fixed
    stack slots and giving them different PseudoSourceValue's did not fix the
    problem of post-alloc scheduling miscompiling llvm itself.
    - Apply Dan's conservative workaround by assuming any non fixed stack slots can
    alias other memory locations. This means a load from spill slot #1 cannot
    move above a store of spill slot #2.
    - Enable post-alloc scheduling for x86 at optimization leverl Default and above.

    Support GoogleTest's "typed tests"
    (http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide#Typed_Tests)
    in lit.py.  These tests have names like "ValueMapTest/0.Iteration", which broke
    when lit.py os.path.join()ed them onto the path and then assumed it could
    os.path.split() them back off.  This patch shifts path components from the
    testPath to the testName until the testPath exists.

    Enhance CodePlacementOpt's unconditional intra-loop branch elimination logic
    to be more general and understand more varieties of loops.

    Teach CodePlacementOpt to reorganize the basic blocks of a loop so that
    they are contiguous. This also includes a fair amount of logic for preserving
    fall-through edges while doing so. This fixes a BranchFolding-ism where blocks
    which can't be made to use a fall-through edge and don't conveniently fit
    anywhere nearby get tossed out to the end of the function.

    Revert svn r80498 and replace it with a different solution.  The only problem
    I can see with the original code was that I forgot that this runs after
    type legalization and hence the result type will always be i32. (Custom
    legalization of EXTRACT_VECTOR_ELT is only enabled for vector types with
    8- and 16-bit elements.)

    Regarding the FIXME comment: any information about sign and zero-extension
    should be captured by separate extension operations.  The DAG combiner should
    handle those to produce either VGETLANEu or VGETLANEs, and that seems to be
    working now.  If there are cases that we're missing, let me know.

    Fix a potential performance problem in placing ARM constant pools.
    In the case where there are no good places to put constants and we fall back
    upon inserting unconditional branches to make new blocks, allow all constant
    pool references in range of those blocks to put constants there, even if that
    means resetting the "high water marks" for those references.  This will still
    terminate because you can't keep splitting blocks forever, and in the bad
    cases where we have to split blocks, it is important to avoid splitting more
    than necessary.

    Fix bug where array malloc with unexpected computation of the size argument resulted in MallocHelper
    identifying the malloc as a non-array malloc.  This broke GlobalOpt's optimization of stores of mallocs
    to global variables.

    The fix is to classify malloc's into 3 categories:
    1. non-array mallocs
    2. array mallocs whose array size can be determined
    3. mallocs that cannot be determined to be of type 1 or 2 and cannot be optimized

    getMallocArraySize() returns NULL for category 3, and all users of this function must avoid their
    malloc optimization if this function returns NULL.

    Eventually, currently unexpected codegen for computing the malloc's size argument will be supported in
    isArrayMalloc() and getMallocArraySize(), extending malloc optimizations to those examples.

    Fix another problem with ARM constant pools.  Radar 7303551.
    When ARMConstantIslandPass cannot find any good locations (i.e., "water") to
    place constants, it falls back to inserting unconditional branches to make a
    place to put them.  My recent change exposed a problem in this area.  We may
    sometimes append to the same block more than one unconditional branch.  The
    symptoms of this are that the generated assembly has a branch to an undefined
    label and running llc with -debug will cause a seg fault.

    This happens more easily since my change to prevent CPEs from moving from
    lower to higher addresses as the algorithm iterates, but it could have
    happened before.  The end of the block may be in range for various constant
    pool references, but the insertion point for new CPEs is not right at the end
    of the block -- it is at the end of the CPEs that have already been placed
    at the end of the block.  The insertion point could be out of range.  When
    that happens, the fallback code will always append another unconditional
    branch if the end of the block is in range.

    The fix is to only append an unconditional branch if the block does not
    already end with one.  I also removed a check to see if the constant pool load
    instruction is at the end of the block, since that is redundant with
    checking if the end of the block is in-range.

    There is more to be done here, but I think this fixes the immediate problem.

    don't bother calling ConstantFoldInstruction unless there is a use of the
    instruction (which disqualifies stores, unreachable, etc) and at least the
    first operand is a constant.  This filters out a lot of obvious cases that
    can't be folded.  Also, switch the IRBuilder to a TargetFolder, which tries
    harder.

    I don't see any point in having both eh.selector.i32 and eh.selector.i64,
    so get rid of eh.selector.i64 and rename eh.selector.i32 to eh.selector.
    Likewise for eh.typeid.for.  This aligns us with gcc, which always uses a
    32 bit value for the selector on all platforms.  My understanding is that
    the register allocator used to assert if the selector intrinsic size didn't
    match the pointer size, and this was the reason for introducing the two
    variants.  However my testing shows that this is no longer the case (I
    fixed some bugs in selector lowering yesterday, and some more today in the
    fastisel path; these might have caused the original problems).

    Another BasicAA fix. If a value does not alias a GEP's base pointer, then it
    cannot alias the GEP. GEP pointer alias rule states this clearly:
    A pointer value formed from a getelementptr instruction is associated with the
    addresses associated with the first operand of the getelementptr.

    type is bigger or smaller than the value's type); or zero
    extending or truncating it.  Use it in a few places (this
    seems to be a popular operation, but I only modified cases
    of it in SelectionDAGBuild).  In particular, the eh_selector
    lowering was doing this wrong due to a repeated rather than
    inverted test, fixed with this change.

    Memory dependence analysis was incorrectly stopping to scan for stores to a pointer at bitcast uses of a malloc call.
    It should continue scanning until the malloc call, and this patch fixes that.

    Delete a comment that makes no sense to me.  The statement that moving a CPE
    before its reference is only supported on ARM has not been true for a while.
    In fact, until recently, that was only supported for Thumb.  Besides that,
    CPEs are always a multiple of 4 bytes in size, so inserting a CPE should have
    no effect on Thumb alignment.

commit e5001730bd4aa9b23daa7861ea3ef08c35e77777
Author: Bob Wilson <bob.wilson@apple.com>
Date:   Mon Oct 12 21:23:15 2009 +0000

    Last week, ARMConstantIslandPass was failing to converge for the
    MultiSource/Benchmarks/MiBench/automotive-susan test.  The failure has
    since been masked by an unrelated change (just randomly), so I don't have
    a testcase for this now.  Radar 7291928.

    The situation where this happened is that a constant pool entry (CPE) was
    placed at a lower address than the load that referenced it.  There were in
    fact 2 CPEs placed at adjacent addresses and referenced by 2 loads that were
    close together in the code.  The distance from the loads to the CPEs was
    right at the limit of what they could handle, so that only one of the CPEs
    could be placed within range.  On every iteration, the first CPE was found
    to be out of range, causing a new CPE to be inserted.  The second CPE had
    been in range but the newly inserted entry pushed it too far away.  Thus the
    second CPE was also replaced by a new entry, which in turn pushed the first
    CPE out of range.  Etc.

    Judging from some comments in the code, the initial implementation of this
    pass did not support CPEs placed _before_ their references.  In the case
    where the CPE is placed at a higher address, the key to making the algorithm
    terminate is that new CPEs are only inserted at the end of a group of adjacent
    CPEs.  This is implemented by removing a basic block from the "WaterList"
    once it has been used, and then adding the newly inserted CPE block to the
    list so that the next insertion will come after it.  This avoids the ping-pong
    effect where CPEs are repeatedly moved to the beginning of a group of
    adjacent CPEs.  This does not work when going backwards, however, because the
    entries at the end of an adjacent group of CPEs are closer than the CPEs
    earlier in the group.

    To make this pass terminate, we need to maintain a property that changes can
    only happen in some sort of monotonic fashion.  The fix used here is to require
    that the CPE for a particular constant pool load can only move to lower
    addresses.  This is a very simple change to the code and should not cause
    any significant degradation in the results.

    allow this testcase to pass with recent changes.  The test hasn't been
    producing any stores at all for a long time, but ".store." was in some
    IR instruction names until recently.  This removal caused the test to
    start failing.  Just make it reject any stores.

    populate instcombine's initial worklist more carefully, causing
    it to visit instructions from the start of the function to the
    end of the function in the first path.  This greatly speeds up
    some pathological cases (e.g. PR5150).

    Try #3, this time with some unneeded debug info stuff removed
    which was causing dead pointers to be added to the worklist.

Author: Chris Lattner <sabre@nondot.org>
Date:   Sun Oct 11 23:02:46 2009 +0000

    remove some harmful code that would turn an insertelement on an undef
    into a shuffle even if it was used by another insertelement.  If the
    visitation order of instcombine was wrong, this would turn a chain of
    insertelements into a chain of shufflevectors, which was quite painful.

    Since CollectShuffleElements handles these cases, the code can just
    be nuked.

    generalize a transformation even more: we don't care whether the
    input the the mul is a zext from bool, just that it is all zeros
    other than the low bit.  This fixes some phase ordering issues
    that would cause us to miss some xforms in mul.ll when the worklist
    is visited differently.

    implement a transformation in jump threading that is currently
    done by condprop, but do it in a much more general form.  The
    basic idea is that we can do a limited form of tail duplication
    in the case when we have a branch on a phi.  Moving the branch
    up in to the predecessor block makes instruction selection
    much easier and encourages chained jump threadings.

    switch GVN to use SSAUpdater.  Besides removing a lot of complexity
    from GVN, this also speeds it up, inserts fewer PHI nodes (see the
    testcase) and allows it to remove more loads (due to fewer PHI nodes
    standing in the way).

Date:   Sat Oct 10 09:05:58 2009 +0000

    Change jump threading to use the new SSAUpdater class instead of
    DemoteRegToStack.  This makes it more efficient (because it isn't
    creating a ton of load/stores that are eventually removed by a later
    mem2reg), and more slightly more effective (because those load/stores
    don't get in the way of threading).

    add some WeakVH::operator='s.  Without these, assigning
    a Value* to a WeakVH was constructing a temporary WeakVH

    Create a new InstrEmitter class for translating SelectionDAG nodes

    ScheduleDAGSDNodesEmit.cpp into a new class. This decouples MachineInstr
    emitting from scheduling.

    Factor out LiveIntervalAnalysis' code to determine whether an instruction
    is trivially rematerializable and integrate it into
    TargetInstrInfo::isTriviallyReMaterializable. This way, all places that
    need to know whether an instruction is rematerializable will get the
    same answer.

    This enables the useful parts of the aggressive-remat option by
    default -- using AliasAnalysis to determine whether a memory location
    is invariant, and removes the questionable parts -- rematting operations
    with virtual register inputs that may not be live everywhere.

    Added another bit of the ARM target assembler to llvm-mc to parse register
    lists.  Changed ARMAsmParser::MatchRegisterName to return -1 instead of 0 on
    errors so 0-15 values could be returned as register numbers.  Also added the
    rest of the arm register names to the currently hacked up version to allow more
    testing.  Some changes to ARMAsmParser::ParseOperand to give different errors
    for things not yet supported and some additions to the hacked
    ARMAsmParser::MatchInstruction to allow more testing for now.

    When considering whether to inline Callee into Caller,
    and that will make Caller too big to inline, see if it
    might be better to inline Caller into its callers instead.
    This situation is described in PR 2973, although I haven't
    tried the specific case in SPASS.

commit b67fb2b7be5c577e88578d240998a7ed3bf210db
Author: Jim Grosbach <grosbach@apple.com>
Date:   Wed Oct 7 17:12:56 2009 +0000

    Add register-reuse to frame-index register scavenging. When a target uses
    a virtual register to eliminate a frame index, it can return that register
    and the constant stored there to PEI to track. When scavenging to allocate
    for those registers, PEI then tracks the last-used register and value, and
    if it is still available and matches the value for the next index, reuses
    the existing value rather and removes the re-materialization instructions.
    Fancier tracking and adjustment of scavenger allocations to keep more
    values live for longer is possible, but not yet implemented and would likely
    be better done via a different, less special-purpose, approach to the
    problem.

    eliminateFrameIndex() is modified so the target implementations can return
    the registers they wish to be tracked for reuse.

    ARM Thumb1 implements and utilizes the new mechanism. All other targets are
    simply modified to adjust for the changed eliminateFrameIndex() prototype.

    Instead of printing unnecessary basic block labels as labels in
    verbose-asm mode, print comments instead. This eliminates a non-comment
    difference between verbose-asm mode and non-verbose-asm mode.

    Also, factor out the relevant code out of all the targets and into
    target-independent code.

    Add instruction flags: hasExtraSrcRegAllocReq and hasExtraDefRegAllocReq. When
    set, these flags indicate the instructions source / def operands have special
    register allocation requirement that are not captured in their register classes.
    Post-allocation passes (e.g. post-alloc scheduler) should not change their

    even / odd register pair.

    Add a new virtual EmitStartOfAsmFile method to the AsmPrinter and use this
    to emit target-specific things at the beginning of the asm output.  This
    fixes a problem for PPC, where the text sections are not being kept together
    as expected.  The base class doInitialization code calls DW->BeginModule()
    which emits a bunch of DWARF section directives.  The PPC doInitialization
    code then emits all the TEXT section directives, with the intention that they
    will be kept together. But as I understand it, the Darwin assembler treats
    the default TEXT section as a special case and moves it to the beginning of
    the file, which means that all those DWARF sections are in the middle of
    the text.  With this change, the EmitStartOfAsmFile hook is called before
    the DWARF section directives are emitted, so that all the PPC text section
    directives come out right at the beginning of the file.

    Add a way for a frontend to generate more complex dwarf location
    information.  This allows arbitrary code involving DW_OP_plus_uconst
    and DW_OP_deref.  The scheme allows for easy extention to include,
    any, or all of the DW_OP_ opcodes.  I thought about just exposing all
    of them, but, wasn't sure if people wanted the dwarf opcodes exposed
    in the api.  Is that a layering violation?

    With this scheme, the entire existing block scheme used by llvm-gcc
    can be switched over to the new scheme.  I think that would be
    cleaner, as then the compiler specific bits are not present in llvm
    proper.  Before the old code can be yanked however, similar code in
    clang would have to be removed.

    Next up, more testing.

    Simplify the tracking of virtual frame index registers. Ranges cannot overlap,
    so a simple "current register" will suffice. Also add some additional
    sanity-checking assertions to make sure things are as we expect.

    Moving register scavenging to a post pass results in virtual registers in
    the instruction we're scavenging for. The scavenger needs to know to avoid
    them when analyzing register usage.

    Coalescer should not delete extract_subreg, insert_subreg, and subreg_to_reg of
    physical registers. This is especially critical for the later two since they
    start the live interval of a super-register. e.g.
    %DO<def> = INSERT_SUBREG %D0<undef>, %S0<kill>, 1
    If this instruction is eliminated, the register scavenger will not be happy as
    D0 is not defined previously.
    This fixes PR5055.

    Move the dominator verification code out of special code embedded within
    the PassManager code into a regular verifyAnalysis method.

    Also, reorganize loop verification. Make the LoopPass infrastructure
    call verifyLoop as needed instead of having LoopInfo::verifyAnalysis
    check every loop in the function after each looop pass. Add a new
    command-line argument, -verify-loop-info, to enable the expensive
    full checking.

    Extend the StartPassTimer and StopPassTimer functions so that the
    code that stops the timer doesn't have to search to find the timer
    object before it stops the timer. This avoids a lock acquisition
    and a few other things done with the timer running.

    When a loop is deleted, immediately release all of the active

    trying to call verifyAnalysis on them, and frees up some memory
    sooner rather than later.

    Instead of testing whether an instruction dominates the loop preheader,
    test whether it properly dominates the loop header. This is equivalent
    when the loop has a preheader, and has the advantage of working when
    the loop doesn't have a preheader. Since IVUsers doesn't Require
    LoopSimplify, the loop isn't guaranteed to have a preheader.

    Move the integer type out of 'derived' and into 'primitive'. This permits us
    to explain that derived types are all composed of other types, which primitive
    types aren't. Without moving integer out of derived, this wouldn't be true.

    Perform a few trivial cleanups; 'i1' went from a link to #t_primitive to
    #t_integer (a holdover from when it was a bool type I suppose).

    Improve MachineMemOperand handling.
     - Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions.
       This eliminates MachineInstr's std::list member and allows the data to be
       created by isel and live for the remainder of codegen, avoiding a lot of
       copying and unnecessary translation. This also shrinks MemSDNode.
     - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated
       fields for MachineMemOperands.
     - Change MemSDNode to have a MachineMemOperand member instead of its own
       fields with the same information. This introduces some redundancy, but
       it's more consistent with what MachineInstr will eventually want.
     - Ignore alignment when searching for redundant loads for CSE, but remember
       the greatest alignment.

    Target-specific code which previously used MemOperandSDNodes with generic
    SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range
    so that the SelectionDAG framework knows that MachineMemOperand information
    is available.

    Rename getTargetNode to getMachineNode, for consistency with the
    naming scheme used in SelectionDAG, where there are multiple kinds
    of "target" nodes, but "machine" nodes are nodes which represent
    a MachineInstr.

    reimplement the regex matching strategy by building a single
    regex and matching it instead of trying to match chunks at a time.
    Matching chunks at a time broke with check lines like
      CHECK: foo {{.*}}bar
    because the .* would eat the entire rest of the line and bar would
    never match.

    Now we just escape the fixed strings for the user, so that something
    like:
      CHECK: a() {{.*}}???
    is matched as:
      CHECK: {{a\(\) .*\?\?\?}}
    transparently "under the covers".

    Generate FSQRT from calls to the sqrt function, which
    allows appropriate backends to generate a sqrt instruction.

    On x86, this isn't done at -O0 because we go through
    FastISel instead.  This is a behavior change from before
    this series of sqrt patches started.  I think this is OK
    considering that compile speed is most important at -O0, but
    could be convinced otherwise.

    pr4926: ARM requires the stack pointer to be aligned, even for leaf functions.
    For the AAPCS ABI, SP must always be 4-byte aligned, and at any "public
    interface" it must be 8-byte aligned.  For the older ARM APCS ABI, the stack
    alignment is just always 4 bytes.  For X86, we currently align SP at
    entry to a function (e.g., to 16 bytes for Darwin), but no stack alignment
    is needed at other times, such as for a leaf function.

    After discussing this with Dan, I decided to go with the approach of adding
    a new "TransientStackAlignment" field to TargetFrameInfo.  This value
    specifies the stack alignment that must be maintained even in between calls.
    It defaults to 1 except for ARM, where it is 4.  (Some other targets may
    also want to set this if they have similar stack requirements. It's not
    currently required for PPC because it sets targetHandlesStackFrameRounding
    and handles the alignment in target-specific code.) The existing StackAlignment
    value specifies the alignment upon entry to a function, which is how we've
    been using it anyway.

    Start of revamping the register scavenging in PEI. ARM Thumb1 is the driving
    interest for this, as it currently reserves a register rather than using
    the scavenger for matierializing constants as needed.

    Instead of scavenging registers on the fly while eliminating frame indices,
    new virtual registers are created, and then a scavenged collectively in a
    post-pass over the function. This isolates the bits that need to interact
    with the scavenger, and sets the stage for more intelligent use, and reuse,
    of scavenged registers.

    For the time being, this is disabled by default. Once the bugs are worked out,
    the current scavenging calls in replaceFrameIndices() will be removed and
    the post-pass scavenging will be the default. Until then,
    -enable-frame-index-scavenging enables the new code. Currently, only the
    Thumb1 back end is set up to use it.

    Fix a hypothetical problem for targets with StackGrowsUp and a non-zero
    LocalAreaOffset.  (We don't have any of those right now.)
    PEI::calculateFrameObjectOffsets includes the absolute value of the
    LocalAreaOffset in the cumulative offset value used to calculate the
    stack frame size.  It then adds the raw value of the LocalAreaOffset
    to the stack size.  For a StackGrowsDown target, that raw value is negative
    and has the effect of cancelling out the absolute value that was added
    earlier, but that obviously won't work for a StackGrowsUp target.  Change
    to subtract the absolute value of the LocalAreaOffset.

    Fix PR5024 with a big hammer: disable the double-def assertion in the scavenger.

    LiveVariables add implicit kills to correctly track partial register kills. This works well enough and is fairly accurate. But coalescer can make it impossible to maintain these markers. e.g.

            BL <ga:sss1>, %R0<kill,undef>, %S0<kill>, %R0<imp-def>, %R1<imp-def,dead>, %R2<imp-def,dead>, %R3<imp-def,dead>, %R12<imp-def,dead>, %LR<imp-def,dead>, %D0<imp-def>, ...
    ...
    	%reg1031<def> = FLDS <cp#1>, 0, 14, %reg0, Mem:LD4[ConstantPool]
    ...
       	%S0<def> = FCPYS %reg1031<kill>, 14, %reg0, %D0<imp-use,kill>

    When reg1031 and S0 are coalesced, the copy (FCPYS) will be eliminated the the implicit-kill of D0 is lost. In this case it's possible to move the marker to the FLDS. But in many cases, this is not possible. Suppose

    	%reg1031<def> = FOO <cp#1>, %D0<imp-def>
    ...
       	%S0<def> = FCPYS %reg1031<kill>, 14, %reg0, %D0<imp-use,kill>

    When FCPYS goes away, the definition of S0 is the "FOO" instruction. However, transferring the D0 implicit-kill to FOO doesn't work since it is the def of D0 itself. We need to fix this in another time by introducing a "kill" pseudo instruction to track liveness.

    Disabling the assertion is not ideal, but machine verifier is doing that job now. It's important to know double-def is not a miscomputation since it means a register should be free but it's not tracked as free. It's a performance issue instead.

    Fix verification of explicit operands.

    The machine code verifier did not check for explicit operands correctly. It
    used MachineInstr::getNumExplicitOperands, but that method may cheat and use
    the declared count in the TargetInstrDesc.

    Fix bug in kill flag updating for post-register-allocation scheduling. When the kill flag of a superreg needs to be cleared because there are one or more subregs live, we instead add implicit-defs of those subregs and leave the kill flag on the superreg. This allows us to end the live-range of the superreg without ending the live-ranges of the subregs.

    Drop the virtual from Value::dump and instead give Value a

    Add a TrackingVH value handle.

    This is designed for tracking a value even when it might move (like WeakVH), but it is an error to delete the referenced value (unlike WeakVH0. TrackingVH is templated like AssertingVH on the tracked Value subclass, it is an error to RAUW a tracked value to an incompatible type.

    For implementation reasons the latter error is only diagnosed on accesses to a mis-RAUWed TrackingVH, because we don't want a virtual interface in a templated class.

    The former error is also only diagnosed on access, so that clients are allowed to delete a tracked value, as long as they don't use it. This makes it easier for the client to reason about destruction.

    %S0<def> = EXTRACT_SUBREG %Q0<kill>, 1
    to
    %S0<def> = IMPLICIT_DEF %Q0<imp-use,kill>

    Implicit_def does not *read* any register so the operand should be marked "implicit". The missing "implicit" marker on the operand is wrong, but it doesn't actually break anything.

    Improve GVN to be able to forward substitute a small load
    from a piece of a large store when both are in the same block.

    This allows clang to compile the testcase in PR4216 to this code:

    _test_bitfield:
    	movl	4(%esp), %eax
    	movl	%eax, %ecx
    	andl	$-65536, %ecx
    	orl	$32962, %eax
    	andl	$40186, %eax
    	orl	%ecx, %eax
    	ret

    This is not ideal, but is a whole lot better than the code produced
    by llvm-gcc:

    _test_bitfield:
    	movw	$-32574, %ax
    	orw	4(%esp), %ax
    	andw	$-25350, %ax
    	movw	%ax, 4(%esp)
    	movw	7(%esp), %cx
    	shlw	$8, %cx
    	movzbl	6(%esp), %edx
    	orw	%cx, %dx
    	movzwl	%dx, %ecx
    	shll	$16, %ecx
    	movzwl	%ax, %eax
    	orl	%ecx, %eax
    	ret

    and dramatically better than that produced by gcc 4.2:

    _test_bitfield:
    	pushl	%ebx
    	call	L3
    "L00000000001$pb":
    L3:
    	popl	%ebx
    	movl	8(%esp), %eax
    	leal	0(,%eax,4), %edx
    	sarb	$7, %dl
    	movl	%eax, %ecx
    	andl	$7168, %ecx
    	andl	$-7201, %ebx
    	movzbl	%dl, %edx
    	andl	$1, %edx
    	sall	$5, %edx
    	orl	%ecx, %ebx
    	orl	%edx, %ebx
    	andl	$24, %eax
    	andl	$-58336, %ebx
    	orl	%eax, %ebx
    	orl	$32962, %ebx
    	movl	%ebx, %eax

    Don't allow formatted_ostream to be unbuffered, even if its underlying buffer
    is.
     - The problem is that formatted_ostream forces its underlying buffer to be
       unbuffered, so if some client happens to wrap a formatted_ostream around
       something, but still use the underlying stream, then we can end up writing on
       a fully unbuffered output (which was never intended to be unbuffered).

     - This makes clang (and presumably llvm-gcc) -emit-llvm -S a mere 10x faster.

    Implement the JIT side of the GDB JIT debugging interface.  To enable this
    feature, either build the JIT in debug mode to enable it by default or pass
    -jit-emit-debug to lli.

    Right now, the only debug information that this communicates to GDB is call
    frame information, since it's already being generated to support exceptions in
    the JIT.  Eventually, when DWARF generation isn't tied so tightly to AsmPrinter,
    it will be easy to push that information to GDB through this interface.

    Here's a step-by-step breakdown of how the feature works:

    - The JIT generates the machine code and DWARF call frame info
      (.eh_frame/.debug_frame) for a function into memory.
    - The JIT copies that info into an in-memory ELF file with a symbol for the
      function.
    - The JIT creates a code entry pointing to the ELF buffer and adds it to a
      linked list hanging off of a global descriptor at a special symbol that GDB
      knows about.
    - The JIT calls a function marked noinline that GDB knows about and has put an
      internal breakpoint in.
    - GDB catches the breakpoint and reads the global descriptor to look for new
      code.
    - When sees there is new code, it reads the ELF from the inferior's memory and
      adds it to itself as an object file.
    - The JIT continues, and the next time we stop the program, we are able to
      produce a proper backtrace.

    Consider running the following program through the JIT:

    #include <stdio.h>
    void baz(short z) {
      long w = z + 1;
      printf("%d, %x\n", w, *((int*)NULL));  // SEGFAULT here
    }
    void bar(short y) {
      int z = y + 1;
      baz(z);
    }
    void foo(char x) {
      short y = x + 1;
      bar(y);
    }
    int main(int argc, char** argv) {
      char x = 1;
      foo(x);
    }

    Here is a backtrace before this patch:
    Program received signal SIGSEGV, Segmentation fault.

    Several changes together in a murky mess:
    1. Change some "\n" -> '\n'.
    2. eliminte some std::string's by using raw_ostream::indent.
    3. move a bunch of code out of the main arg parser routine into
       a new static HandlePrefixedOrGroupedOption function.
    4. Greatly simplify the implementation of getOptionPred, and make
       it avoid splitting prefix options at = when that doesn't match
       a non-prefix option.

    Here's fun! It turns out that these filter functions can be internal. If they're
    internal, they shouldn't use the indirect pointer stuff. In the case of
    throw_rethrow_test, it was marked as 'internal' and calculated its own offset to
    its contents.

    When computing live intervals for earlyclobber operands,
    we pushed the beginning of the interval back 1, so the
    interval would overlap with inputs that die.  We were
    also pushing the end of the interval back 1, though,
    which means the earlyclobber didn't overlap with other

    this is run after the 'standard function passes', SRoA was
    recently run.  This saves a domfrontier construction. Thanks

    It's inefficient to have place the exception tables (which contain the LSDA)
    into the __DATA section. At launch time, dyld has to update most of the section
    to fix up the type info pointers. It's better to place it into the __TEXT
    section and use pc-rel indirect pointer encodings. Similar to the personality
    routine.

    Make a new X8632_MachoTargetObjectFile TLOF implementation whose
    getSymbolForDwarfGlobalReference is smart enough to know that it
    needs to register the stub it references with MachineModuleInfoMachO,
    so that it gets emitted at the end of the file.

    Move stub emission from X86ATTAsmPrinter::doFinalization to the
    new X86ATTAsmPrinter::EmitEndOfAsmFile asmprinter hook.  The important
    thing here is that EmitEndOfAsmFile is called *after* the ehframes are
    emitted, so we get all the stubs.

    This allows us to remove a gross hack from the asmprinter where it would
    "just know" that it needed to output stubs for personality functions.
    Now this is all driven from a consistent interface.

    The testcase change is just reordering the expected output now that the
    stubs come out after the ehframe instead of before.

    This also unblocks other changes that Bill wants to make.

    Ensure that ArraySize in LowerAllocations::runOnBasicBlock() is correct type.

    This can be seen on CodeGen/Generic/2006-09-06-SwitchLowering.ll. But it's not known to cause any real regression (but I have added an assertion for it now).

    Add a new pass for doing late hoisting of floating-point and vector
    constants out of loops. These aren't covered by the regular LICM
    pass, because in LLVM IR constants don't require separate
    instructions. They're not always covered by the MachineLICM pass
    either, because it doesn't know how to unfold folded constant-pool
    loads. This is somewhat experimental at this point, and off by
    default.

    Do not try and sink a load whose chain result has more than one use, when
    trying to create RMW opportunities in the x86 backend.  This can cause a
    cycle to appear in the graph, since the other uses may eventually feed into
    the TokenFactor we are sinking the load below.

    Don't sink gep operators through phi nodes if the result would require
    more than one phi, since that leads to higher register pressure on
    entry to the phi. This is especially problematic when the phi is in
    a loop header, as it increases register pressure throughout the loop.

    Big change #1 for personality function references:
    Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
    fields from MAI: they aren't part of the asm syntax, they are
    related to the structure of the object file.

    To replace their functionality, add a new
    TLOF::getSymbolForDwarfGlobalReference method which asks targets
    to decide how to reference a global from EH in a pc-relative way.

    The default implementation just returns the symbol.  The default
    darwin implementation references the symbol through an indirect
    $non_lazy_ptr stub.  The bizarro x86-64 darwin specialization
    handles the weird "foo@GOTPCREL+4" hack.

    DwarfException.cpp now uses this to emit the reference to the
    symbol in the right way, and this also eliminates another
    horrible hack from DwarfException.cpp:

    -    if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))
    -      O << "-" << MAI->getPCSymbol();

    Added a variety of floating-point and SSE instructions.
    All of these do not have patterns (they're for the

    Many of the floating-point instructions will probably
    be rolled into definitions that have patterns, and may
    eventually be superseded by mdefs.  So I put them
    together and left a comment.

    eliminate the PPC backend's implementation of EmitExternalGlobal
    and use PersonalityPrefix/Suffix to achieve the same effect (like
    the x86 backend).

    This changes the code generated for ppc static mode, but guess what,
    we were generating this before:

    	.byte	0x9B                                        ; Personality (indirect pcrel sdata4)
    	.long	___gxx_personality_v0-.                     ; Personality

    which is not correct! (it is not an 'indirect' reference).

    Change the marker byte for stubs from 0xcd to 0xce (another form of
    interrupt instruction, which shouldn't arise any other way).  0xcd is
    also used by JITMemoryManager to initialize the buffer to garbage,

    Handle AddrMode4 for Thumb2 in rewriteT2FrameIndex.  This occurs for
    VLDM/VSTM instructions, and without this check, the code assumes that an
    offset is allowed, as it would be with VLDR/VSTR.  The asm printer,
    however, silently drops the offset, producing incorrect code.  Since the
    address register in this case is either the stack or frame pointer, the
    spill location ends up conflicting with some other stack slot or with
    outgoing arguments on the stack.

commit 72444efbd46645993821a5167411656371e995b1
Author: Dan Gohman <gohman@apple.com>
Date:   Tue Sep 15 15:58:07 2009 +0000

    When a constant's type is refined, update the constant in place
    instead of cloning and RAUWing it.

     - Make AbstractTypeUser a friend of Value so that it can offer
       its subclasses a way to update a Value's type in place. This
       is better than a universally visible setType method on Value,
       and it's sufficient for the immediate need.

     - Eliminate the constant "convert" functions. This eliminates a
       lot of logic duplication, and fixes a complicated bug where a
       constant can't actually be cloned during the type refinement
       process because some of the types that its folder needs are
       half-destroyed, being in the middle of refinement themselves.

     - Move the getValType functions from being static overloaded
       functions in Constants.cpp to be members of class template
       specializations in ConstantsContext.h. This means that the
       code ends up getting instantiated twice, however it also
       makes it possible to eliminate all "convert" functions, so
       it's not a big net code size increase. And if desired, the
       duplicate instantiations could be eliminated with some
       reorganization.

    Substantially speed up combiner-aa in the following ways:

    1. Switch from an std::set to a SmallPtrSet for visited chain nodes.
    2. Do not force the recursive flattening of token factor nodes, regardless of
       use count.
    3. Immediately process newly created TokenFactor nodes.

    Also, improve combiner-aa by teaching it that loads to non-overlapping offsets
    of relatively aligned objects cannot alias.

    These changes result in a >5x speedup for combiner-aa on most testcases.

    Add early coalescing to liveintervals. This is work in progress and is known to miscompute some tests. Read it at your own rish, I have aged 10 year while writing this.

    The gist of this is if source of some of the copies that feed into a phi join is defined by the phi join, we'd like to eliminate them. However, if any of the non-identity source overlaps the live interval of the phi join then the coalescer won't be able to coalesce them. The early coalescer's job is to eliminate the identity copies by partially-coalescing the two live intervals.

    Change MCAsmStreamer to take an MCInstPrinter instead of a
    full AsmPrinter, and change TargetRegistry to keep track
    of registered MCInstPrinters.

    llvm-mc is still linking in the entire

    important step in the right direction.

    Storing a set of PATypeHolders is a bad idea because their sort order will
    change as types are refined. Remove abstract types from CheckedTypes when they
    we're informed that they have been refined. The only way types get refined in
    the verifier is when later function passes start optimizing. Fixes PR4970.

    X86MCInstLower::Lower should only not emit anything to OutStreamer,

Author: Dan Gohman <gohman@apple.com>
Date:   Fri Sep 11 20:46:33 2009 +0000

    Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't
    working. To support this, add an is_displayed() function to raw_ostream,
    and generalize Process::StandardOutIsDisplayed and friends in order to
    support it.

    Also, call RemoveFileOnSignal before creating a file instead of after, so
    that the file isn't left behind if the program is interrupted between when
    the file is created and RemoveFileOnSignal is called.

    While here, add a -S to llvm-extract and port it to IRReader so that it
    supports assembly input.

    add a new Mangler::getNameWithPrefix API which returns the
    (uniqued if unnamed) global variable name with the prefix that
    it is supposed to get.  It doesn't do "mangling" in the sense of
    adding quotes and hacking on bad characters.

    It's not legal to fold a load from a narrower stack slot into a wider instruction. If done, the instruction does a 64-bit load and that's not
    safe. This can happen we a subreg_to_reg 0 has been coalesced. One
    exception is when the instruction that folds the load is a move, then we
    can simply turn it into a 32-bit load from the stack slot.

    Teach lib/VMCore/ConstantFold.cpp how to set the inbounds keyword and
    how to fold notionally-out-of-bounds array getelementptr indices instead
    of just doing these in lib/Analysis/ConstantFolding.cpp, because it can
    be done in a fairly general way without TargetData, and because not all
    constants are visited by lib/Analysis/ConstantFolding.cpp. This enables
    more constant folding.

    Also, set the "inbounds" flag when the getelementptr indices are
    one-past-the-end.

    within the notional bounds of the static type of the getelementptr (which
    is not the same as "inbounds") from GlobalOpt into a utility routine,
    and use it in ConstantFold.cpp to check whether there are any mis-behaved
    indices.

    Don't hardcode the TType format size. In fact, rework the code so that it's more

    does, though.

    Believe it or not, this is a simplification. :-)

    Basically, this patch is working towards removing the hard-coded values that are
    output for the CIE. In particular, the CIE augmentation and the CIE augmentation
    size. Both of these should be calculated. In the process, I was able to make a
    bunch of code simpler.

    The encodings for the personality, LSDA, and FDE in the CIE are still not
    correct. They should be generated either from target-specific callbacks (blech!)
    or grokked from first-principles.

    remove DebugLoc from MCInst and eliminate "Comment printing" from
    the MCInst path of the asmprinter.  Instead, pull comment printing
    out of the autogenerated asmprinter into each target that uses the
    autogenerated asmprinter.  This causes code duplication into each
    target, but in a way that will be easier to clean up later when more
    asmprinter stuff is commonized into the base AsmPrinter class.

    This also fixes an xcore strangeness where it inserted two tabs
    before every instruction.

    hoist the call to processDebugLoc out of the generated
    asm printer into the "printInstruction" routine.  This
    fixes a problem where the experimental asmprinter would
    drop debug labels in some cases, and fixes issues on ppc/xcore
    where pseudo instructions like "mr" didn't get debug locs properly.

    It is annoying that this moves the call from one place into each
    target, but a future set of more invasive refactorings will fix
    that problem.

    Fix SplitCriticalEdge to properly update LCSSA form when splitting a

    splits that are made to preserve LoopSimplify form, but also for the
    original split. Factor out the code that inserts new PHIs so that it
    can be used for both. Remove LoopRotation.cpp's code for manually
    updating LCSSA form, as it is now redundant. This fixes PR4934.

    Make TypeBuilder's result depend on the LLVMContext it's passed.
    TypeBuilder was using a local static variable to cache its result. This made it
    ignore changes in its LLVMContext argument and always return a type constructed
    from the argument to the first call.

    Re-apply r80926, with fixes: keep the domtree informed of new blocks
    that get created during loop unswitching, and fix SplitBlockPredecessors'
    LCSSA updating code to create new PHIs instead of trying to just move
    existing ones.

    Also, optimize Loop::verifyLoop, since it gets called a lot. Use
    searches on a sorted list of blocks instead of calling the "contains"
    function, as is done in other places in the Loop class, since "contains"
    does a linear search. Also, don't call verifyLoop from LoopSimplify or
    LCSSA, as the PassManager is already calling verifyLoop as part of
    LoopInfo's verifyAnalysis.

    instcombine transforms vector loads that are only used by
    extractelement operations into a bitcast of the pointer,
    then a gep, then a scalar load.  Disable this when the vector
    only has one element, because it leads to infinite loops in
    instcombine (PR4908).

    This transformation seems like a really bad idea to me, as it
    will likely disable CSE of vector load/stores etc and can be
    better done in the code generator when profitable.  This
    goes all the way back to the first days of packed types,
    r25299 specifically.

    I'll let those people who care about the performance of vector
    code decide what to do with this.

Date:   Mon Sep 7 23:47:14 2009 +0000

    Fix a thinko: When lowering fneg with xor, bitcast the operands
    from floating-point to integer first, and bitcast the result
    back to floating-point. Previously, this test was passing by
    falling back to SelectionDAG lowering. The resulting code isn't
    as nice, but it's correct and CodeGen now stays on the fast path.

    Don't commit stores with addresses that have indices that are not
    compile-time constant integers or that are out of bounds for their
    corresponding static array types. These can cause aliasing that
    GlobalOpt assumes won't happen.

    Fix GlobalOpt to avoid committing a store if the address getelementptr
    is missing the inbounds flag. This is slightly conservative, but it
    avoids problems with two constants pointing to the same address but
    getting distinct entries in the Memory DenseMap.

    Now that googletest can print ConstantRange, use EXPECT_EQ when testing for
    equality. Prefer EXPECT_EQ(foo, Full) over EXPECT_TRUE(foo.isFullSet()) because
    the former will print out the contents of the constant range that failed.

    Stabilize the order of live intervals in the priority_queue used by the
    linear scan reg alloc.  This fixes a problem I ran into where extracting
    a function from a larger file caused the generated code to change (masking
    the problem I was trying to debug) because the allocator behaved differently.

    This changes the results for two X86 regression checks.  stack-color-with-reg
    is improved, with one less instruction, but pr3495 is worse, with one more
    copy.  As far as I can tell, these tests were just getting lucky or unlucky,
    so I've changed the expected results.

Date:   Fri Sep 4 12:08:11 2009 +0000

    Include optional subclass flags, such as inbounds, nsw, etc., in the
    Constant uniquing tables. This allows distinct ConstantExpr objects
    with the same operation and different flags.

    Even though a ConstantExpr "a + b" is either always overflowing or
    never overflowing (due to being a ConstantExpr), it's still necessary
    to be able to represent it both with and without overflow flags at
    the same time within the IR, because the safety of the flag may
    depend on the context of the use. If the constant really does overflow,
    it wouldn't ever be safe to use with the flag set, however the use
    may be in code that is never actually executed.

    This also makes it possible to merge all the flags tests into a single test.

    Replace ocamlc tests with ocamlopt tests since they're less noisy.

    There's a bug with ocamlc that uses "char*" instead of "const char*" for
    global string variables. This causes g++ to be very noisy when linking
    ocamlc programs. That's why the ocaml test used to cat to /dev/null.
    ocamlopt doesn't have this problem, so we can get rid of the >/dev/null,
    which may obscure some problems.

    Remove the API for creating ConstantExprs with the nsw, nuw, inbounds,
    and exact flags. Because ConstantExprs are uniqued, creating an
    expression with this flag causes all expressions with the same operands
    to have the same flag, which may not be safe. Add, sub, mul, and sdiv
    ConstantExprs are usually folded anyway, so the main interesting flag
    here is inbounds, and the constant folder already knows how to set the
    inbounds flag automatically in most cases, so there isn't an urgent need
    for the API support.

    This can be reconsidered in the future, but for now just removing these
    API bits eliminates a source of potential trouble with little downside.

    Make ImmutableMap/ImmutableSet quicker by only canonicalizing the tree after an
    Add or Remove operation complete, and not while building the intermediate tree.
    This trades a little bit more memory usage for less accesses to the FoldingSet.  On a benchmark for the clang static analyzer, this shaves off another 13% of execution time when using field/array sensitivity.

    Overhaul the TwoAddressInstructionPass to simplify the logic, especially
    for the complicated case where one register is tied to multiple destinations.
    This avoids the extra scan of instruction operands that was introduced by
    my recent change.  I also pulled some code out into a separate
    TryInstructionTransform method, added more comments, and renamed some
    variables.

    Besides all those changes, this takes care of a FIXME in the code regarding
    an assumption about there being a single tied use of a register when
    converting to a 3-address form.  I'm not aware of cases where that assumption
    is violated, but the code now only attempts to transform an instruction,
    either by commuting its operands or by converting to a 3-address form,
    for the simple case where there is a single pair of tied operands.

    Fixed a few problems with vector shifts
      - when transforming a vector shift of a non-immediate scalar shift amount, zero
        extend the i32 shift amount to i64 since the vector shift reads 64 bits
      - when transforming i16 vectors to use a vector shift, zero extend i16 shift amount
      - improve the code quality in some cases when transforming vectors to use a vector shift

    Implement support for X86II::MO_GOT_ABSOLUTE_ADDRESS.  We get very
    different formatting from the old asmprinter, but it should be
    semantically the same.  We used to get:

    	popl	%eax
    	addl	$_GLOBAL_OFFSET_TABLE_ + [.-.Lllvm$6.$piclabel], %eax
    ...

    Now we get:

    	popl	%eax
    .Lpicbaseref6:
    	addl	$(_GLOBAL_OFFSET_TABLE_ + (.Lpicbaseref6 - .Lllvm$6.$piclabel)), %eax
    ...

    In C++, code is not allowed to call main.  In C it is, this
    simplifylibcalls optimization is thus valid for C++ but not C.
    It's not important enough to worry about for C++ apps, so just
    remove it.

    Set the 'cached digest' flag after computing the digest for an
    ImutAVLTree.  This was accidentally left out, and essentially caused
    digest caching to be ignored in ImmutableMap and ImmutableSet (this
    bug was detected from shark traces that showed ComputeDigest was in
    the hot path in the clang static analyzer).

    This reduces the running time of the clang static analyzer on an
    example benchmark by ~32% for both RegionStore (field-sensitivty) and
    BasicStore (without field-sensitivity).

    edge-profiling, this is more useful since the loading of the

    desired triplet is a sub-target, e.g. thumbv7 vs. arm host). Reverting the

    Preparation for Optimal Edge Profiling:
    Optimal edge profiling is only possible when blocks with no predecessors get an
    virtual edge (BB,0) that counts the execution frequencies of this
    function-exiting blocks.
    This patch makes the necessary changes before actually enabling optimal edge profiling.

    Change CallGraphNode to maintain it's Function as an AssertingVH
    for sanity.  This didn't turn up any bugs.

    Change CallGraphNode to maintain its "callsite" information in the
    call edges list as a WeakVH instead of as an instruction*.  This fixes
    a broad class of dangling pointer bugs, and makes CallGraph have a number
    of useful invariants again.  This fixes the class of problem indicated
    by PR4029 and PR3601.

    Clean up LSDA name generation and use for SJLJ exception handling. This
    makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
    and making it a GV available for reference would be even better, but is
    beyond the scope of what I'm looking to solve at this point.

    Objective C++ code could generate function names that broke the previous
    scheme. This fixes that.

    Extend the ValuesAtScope cache to cover all expressions, not just
    SCEVUnknowns, as the non-SCEVUnknown cases in the getSCEVAtScope code
    can also end up repeatedly climing through the same expression trees,
    which can be unusably slow when the trees are very tall.

    Also, add a quick check for SCEV pointer equality to the main
    SCEV comparison routine, as the full comparison code can be expensive
    in the case of large expression trees.

    These fix compile-time problems in some pathlogical cases.

    Free the constants that have no uses in ~LLVMContext.
    This fixes leaks from LLVMContext in multithreaded apps.
    Since constants are only deleted if they have no uses, it is safe to not delete
    a Module on shutdown, as many single-threaded tools do.
    Multithreaded apps should however delete the Module before destroying the
    Context to ensure that there are no leaks (assuming they use a different context
    for each thread).

commit 298ea10f4da28d9be51f8be5af59f88ea86ce7ec
Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Aug 31 07:23:46 2009 +0000

    Step #1 to giving Callgraph some sane invariants.  The problems with callgraph
    stem from the fact that we have two types of passes that need to update it:

    1. callgraphscc and module passes that are explicitly aware of it
    2. Functionpasses (and loop passes etc) that are interlaced with CGSCC passes
       by the CGSCC Passmgr.

    In the case of #1, we can reasonably expect the passes to update the call
    graph just like any analysis.  However, functionpasses are not and generally
    should not be CG aware.  This has caused us no end of problems, so this takes
    a new approach.  Logically, the CGSCC Pass manager can rescan every function
    after it runs a function pass over it to see if the functionpass made any
    updates to the IR that affect the callgraph.  This allows it to catch new calls
    introduced by the functionpass.

    In practice, doing this would be slow.  This implementation keeps track of
    whether or not the current scc is dirtied by a function pass, and, if so,
    delays updating the callgraph until it is actually needed again.  This was
    we avoid extraneous rescans, but we still have good invariants when the
    callgraph is needed.

    Step #2 of the "give Callgraph some sane invariants" is to change CallGraphNode
    to use a CallBackVH for the callsite entry of the CallGraphNode.  This way
    we can immediately remove entries from the callgraph when a FunctionPass is
    active instead of having dangling pointers.  The current pass tries to tolerate
    these dangling pointers, but it is just an evil hack.

    This is related to PR3601/4835/4029.  This also reverts r80541, a hack working
    around the sad lack of invariants.

    simplify some code by making the SCCNodes set contain Function*'s
    instead of CallGraphNode*'s.  This also papers over a callgraph
    problem where a pass (in this case, MemCpyOpt) introduces a new
    function into the module (llvm.memset.i64) but doesn't add it to
    the call graph (nor should it, since it is a function pass).

    While it might be a good idea for MemCpyOpt to not synthesize
    functions in a runOnFunction(), there is no need for FunctionAttrs
    to be boneheaded, so fix it there.  This fixes an assertion building
    176.gcc.

    Fix PR4834, a tricky case where the inliner would resolve an
    indirect function pointer, inline it, then go to delete the body.
    The problem is that the callgraph had other references to the function,
    though the inliner had no way to know it, so we got a dangling pointer
    and an invalid iterator out of the deal.

    The fix to this is pretty simple: stop the inliner from deleting the
    function by knowing that there are references to it.  Do this by making
    CallGraphNodes contain a refcount.  This requires moving deletion of
    available_externally functions to the module-level cleanup sweep where
    it belongs.

    PR4747

    Shared landing pads run into trouble with SJLJ, as the dispatch table is
    mapped to call sites, and merging the pads will throw that off. There needs
    to be a one-to-one mapping of landing pad exception table entries to invoke
    call points.

    Detecting the shared pad during lowering of SJLJ info insn't sufficient, as
    the dispatch function may still need separate destinations to properly
    handle phi-nodes.

    Fix some nasty callgraph dangling pointer problems in
    argpromotion and structretpromote.  Basically, when replacing
    a function, they used the 'changeFunction' api which changes
    the entry in the function map (and steals/reuses the callgraph
    node).

    This has some interesting effects: first, the problem is that it doesn't
    update the "callee" edges in any callees of the function in the call graph.
    Second, this covers for a major problem in all the CGSCC pass stuff, which
    is that it is completely broken when functions are deleted if they *don't*
    reuse a CGN.  (there is a cute little fixme about this though :).

    This patch changes the protocol that CGSCC passes must obey: now the CGSCC
    pass manager copies the SCC and preincrements its iterator to avoid passes
    invalidating it.  This allows CGSCC passes to mutate the current SCC.  However
    multiple passes may be run on that SCC, so if passes do this, they are now
    required to *update* the SCC to be current when they return.

    Other less interesting parts of this patch are that it makes passes update
    the CG more directly, eliminates changeFunction, and requires clients of
    replaceCallSite to specify the new callee CGN if they are changing it.

    Fix PR4748:  don't fold gep(bitcast(x)) into bitcast(gep) when x
    is itself a bitcast.  Since we have gep(bitcast(bitcast(y))) in this
    case, just wait for the two bitcasts to get zapped.  This prevents
    instcombine from confusing some aliasing stuff, and allows it to
    directly eliminate the load in the testcase.

Date:   Sun Aug 30 07:44:24 2009 +0000

    give instcombine a custom IRBuilder that adds new instructions to the
    workslist and is set to insert new instructions before the current one.
    Convert a bunch of stuff that used to call InsertNewInstBefore over to
    use it, greatly simplifying code and making it more natural.

    There is still a lot more to go, but this is a good start.

    inline the trivial AddToWorkList/RemoveFromWorkList methods
    into their callers.  simplify ReplaceInstUsesWith.  Make
    EraseInstFromFunction only add operands to the worklist if
    there aren't too many of them (this was a scalability win
    for crazy programs that was only infrequently enforced).
    Switch more code to using EraseInstFromFunction instead of
    duplicating it inline.  Change some fcmp/icmp optimizations
    to modify fcmp/icmp in place instead of creating a new one
    and deleting the old one just to change the predicate.

    PR4795: Remove EEVT::isFP, isInt and isVec types used by TableGen's type
    inferencing.  As far as I can tell, these are equivalent to the existing
    MVT::fAny, iAny and vAny types, and having both of them makes it harder
    to reason about and modify the type inferencing code.

    The specific problem in PR4795 occurs when updating a vAny type to be fAny
    or iAny, or vice versa.  Both iAny and fAny include vector types -- they
    intersect with the set of types represented by vAny.  When merging them,
    choose fAny/iAny to represent the intersection.  This is not perfect, since
    fAny/iAny also include scalar types, but it is good enough for TableGen's
    type inferencing.

    make check twice), since execution counts will differ.

    llvm-mc/X86: Implement single instruction encoding interface for MC.
     - Note, this is a gigantic hack, with the sole purpose of unblocking further
       work on the assembler (its also possible to test the mathcer more completely
       now).

     - Despite being a hack, its actually good enough to work over all of 403.gcc
       (although some encodings are probably incorrect). This is a testament to the
       beauty of X86's MachineInstr, no doubt! ;)

Author: Chris Lattner <sabre@nondot.org>
Date:   Thu Aug 27 06:29:33 2009 +0000

    Implement a new optimization in the inliner: if inlining multiple
    calls into a function and if the calls bring in arrays, try to merge
    them together to reduce stack size.  For example, in the testcase
    we'd previously end up with 4 allocas, now we end up with 2 allocas.

    As described in the comments, this is not really the ideal solution
    to this problem, but it is surprisingly effective.  For example, on
    176.gcc, we end up eliminating 67 arrays at "gccas" time and another
    24 at "llvm-ld" time.

    One piece of concern that I didn't look into: at -O0 -g with
    forced inlining this will almost certainly result in worse debug
    info.  I think this is acceptable though given that this is a case
    of "debugging optimized code", and we don't want debug info to
    prevent the optimizer from doing things anyway.

Author: Dan Gohman <gohman@apple.com>
Date:   Thu Aug 27 00:14:12 2009 +0000

    Expand i8 selects into control flow instead of 16-bit conditional
    moves. This avoids the need to promote the operands (or implicitly
    extend them, a partial register update condition), and can reduce
    i8 register pressure. This substantially speeds up code such as
    write_hex in lib/Support/raw_ostream.cpp.

    subclass-coalesce.ll is too trivial and no longer tests what it was
    originally intended to test.

    Create a ScalarEvolution-based AliasAnalysis implementation.

    This is a simple AliasAnalysis implementation which works by making
    ScalarEvolution queries. ScalarEvolution has a more complete understanding
    of arithmetic than BasicAA's collection of ad-hoc checks, so it handles
    some cases that BasicAA misses, for example p[i] and p[i+1] within the
    same iteration of a loop.

    This is currently experimental. It may be that the main use for this pass
    will be to help find cases where BasicAA can be profitably extended, or
    to help in the development of the overall AliasAnalysis infrastructure,
    however it's also possible that it could grow up to become a directly
    useful pass.

    llvm-mc/Mach-O: Add support for relocations.
     - I haven't really tried to find the "right" way to store the fixups or apply

Author: Dan Gohman <gohman@apple.com>
Date:   Tue Aug 25 22:11:20 2009 +0000

    Rename Instruction::isIdenticalTo to Instruction::isIdenticalToWhenDefined,
    and introduce a new Instruction::isIdenticalTo which tests for full
    identity, including the SubclassOptionalData flags. Also, fix the
    Instruction::clone implementations to preserve the SubclassOptionalData
    flags. Finally, teach several optimizations how to handle
    SubclassOptionalData correctly, given these changes.

    This fixes the counterintuitive behavior of isIdenticalTo not comparing
    the full value, and clone not returning an identical clone, as well as
    some subtle bugs that could be caused by these.

    Thanks to Nick Lewycky for reporting this, and for an initial patch!

    Add a target asm info hook to specify that particular bits of data in the FDE
    should be forced to 32-bits (.long) even on 64-bit architectures. Darwin wants
    these bits to be 64-bits (.quad). However, other platforms may disagree.

    This is just the info right now and is part of a work-in-progress which needs
    this. We'll add the actual *use* of this soon.

    Special-case static allocas in IndVarSimplify's loop invariant
    sinking code, since they are special. If the loop preheader happens
    to be the entry block of a function, don't sink static allocas
    out of it. This fixes PR4775.

    Allocate the basic types inside the LLVMContextImpl instance,
    rather than separately with new. Move the members above the
    TypeMap members to avoid destruction order issues. This fixes
    a leak of these objects, and eliminates an extra level of
    indirection in Type::getInt32Ty and friends.

    Make LLVM command-line tools overwrite their output files without -f.
    This is conventional command-line tool behavior. -f now just means
    "enable binary output on terminals".

    Add a -f option to llvm-extract and llvm-link, for consistency.

    Remove F_Force from raw_fd_ostream and enable overwriting and
    truncating by default. Introduce an F_Excl flag to permit users to
    enable a failure when the file already exists. This flag is
    currently unused.

    Update Makefiles and documentation accordingly.

    Resubmit an earlier patch of mine:
    reduce the size of relevant "ghostly" sentinels
    by a pointer.

    This attempt now makes the compactification dependent
    on the configure variable LLVM_COMPACT_SENTINELS
    and should not cause any bootstrap failures for
    llvm-gcc any more.

    Please note that this is not yet the final version,
    and (as settled with Chris) I shall take out the
    autofoo/cmake portions in the next days.

    This will also lose the assertability on sentinel
    dereferencing and operator++, but that seems
    an acceptable price to pay for the simplified
    build logic.
