24cb93723b Merge LLVM upstream SVN r97877. 
This brings in the new ISel emitter, which should improve build times,
and code size.

Squashed commit of the following:

commit 8b8baa7196d3ee855a618977101333cca26db4dc
Author: Anton Korobeynikov <asl@math.spbu.ru>
Date:   Sat Mar 6 11:41:12 2010 +0000

    Do not use '&' prefix for globals when register base field is non-zero, otherwise msp430-as will silently miscompile the code (TI's assembler report an error though).

    This fixes PR6349

    Migrate _chk call lowering from SimplifyLibCalls to InstCombine. Stub
    out the remainder of the calls that we should lower in some way and
    move the tests to the new correct directory. Fix up tests that are now
    optimized more than they were before by -instcombine.

    Thumb1 epilogue code generation needs to take into account that callee-saved
    registers may be restored via a pop instruction, not just a tRestore.

    Modified:
       llvm/trunk/lib/Transforms/InstCombine/InstCombineCalls.cpp
       llvm/trunk/test/Transforms/InstCombine/objsize.ll

    It appears to be causing swb and nightly test failures.

    Don't emit global symbols into the (__TEXT,__ustring) section on Darwin. This
    is a workaround for <rdar://problem/7672401/> (which I filed).

    This let's us build Wine on Darwin, and it gets the Qt build there a little bit
    further (so Doug says).

Author: Jakob Stoklund Olesen <stoklund@2pi.dk>

    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.

    Fix PR6503.  This turned into a much more interesting and nasty bug.  Various
    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.

    Fix PR6360.  It's easy for a stub's address to escape to user code, so we can't
    just count references to it from JIT output to decide when to destroy it.  This
    patch waits to destroy the JIT's memory of a stub until the Function it refers

    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.

    Teach lit to honor conditional directives.  The syntax is:
      IF(condition(value)):
    If the value satisfies the condition, the line is processed by lit;  otherwise
    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.

    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

    introduce a new SwitchTypeMatcher node (which is analogous to
    SwitchOpcodeMatcher) and have DAGISelMatcherOpt form it.  This
    speeds up selection, particularly for X86 which has lots of
    variants of instructions with only type differences.

    - 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.

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.

    Fix PR2590 by making PatternSortingPredicate actually be
    ordered correctly.  Previously it would get in trouble when
    two patterns were too similar and give them nondet ordering.
    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:

    < 	lda $0,-100($16)
    ---
    > 	subq $16,100,$0

    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 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.

    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.

    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.

    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.

    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

    Improve the vim code for highlighting trailing whitespace and lines
    longer than 80 columns. This replaces the heavy-handed "textwidth"
    mechanism, and makes the trailing-whitespace highlighting lazy so
    that it isn't constantly jumping on the user during typing.

commit d21af378e4c987c368684e57fb90ec61660f95b8
Author: Jakob Stoklund Olesen <stoklund@2pi.dk>
Date:   Fri Feb 26 21:09:24 2010 +0000

    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! :)

    Add another (and hopefully the last) exception case, where once we recalculate
    the alignment requirement, if it no longer makes the TType base offset overflow
    into extra bytes, then we need to pad to those bytes ourselves.

    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
            .byte   0x03  ## Call site Encoding = udata4
            .byte   0x89  ## Call site table length

    with padding of 1. We want to emit the padding like this:

        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.

    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

    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.

    This fixes PR6370

    The new isel was not properly handling patterns that covered

    OPC_MarkFlagResults opcode and use this to update the interior

    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.

    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.

Date:   Tue Feb 23 16:27:59 2010 +0000

    Modified examples Makefile to only build the ExceptionDemo example for
    x86 and x86_64 on UNIX systems. Only OS X 10.6.2 (x86_64) and 32bit CentOS 5.2
    with gcc 4.1.2 were tested. ARM UNIX build triggered failure motivating this
    modification, as it seems that the ARM ABI does not support _Unwind_GetIP(...),
    _Unwind_SetGR(...), and _Unwind_SetIP(...). From doing a quick browse of:
    http://infocenter.arm.com/help/topic/com.arm.doc.ihi0038a/IHI0038A_ehabi.pdf,
    it seems as if all other exception related apis are supported. Looks like
    the port can be done to ARM. Thanks to Xerxes Rånby <xerxes@zafena.se> for
    pointing out this error.

commit e3a42e30c5cbb5c69a8a61c4ea995a644d730da1
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.

    Instcombine constant folding can normalize gep with negative index to index with large offset. When instcombine objsize checking transformation sees these geps where the offset seemingly point out of bound, it should just return "i don't know" rather than asserting.

    Change ComplexPattern handling to push the node being matched as

    allows CheckSame to work correctly when matching replicated

    failures, we're down to 13 failures, two of which are
    due to a sched bug.

    Canonicalize ConstantInts to the right operand of commutative

    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.

    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

    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.

Date:   Thu Feb 18 02:36:02 2010 +0000

    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.

Date:   Tue Feb 16 21:09:44 2010 +0000

    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.

    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

    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.

    Teach MachineFrameInfo to track maximum alignment while stack objects are being

    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.

    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.

    movhps	(%ecx,%eax,2), %xmm2

    movq     (%eax, %edx, 2), %xmm2
    movq     (%eax, %ebx, 2), %xmm3

    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.

    Make it possible to create multiple JIT instances at the same time, by removing

    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.

    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.

    MC/AsmMatcher: Add support for creating tied operands when constructing MCInsts.

    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.

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.

    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.

    rejigger the world so that EmitInstruction prints the \n at
    the end of the instruction instead of expecting the caller to
    do it.  This currently causes the asm-verbose instruction
    comments to be on the next line.

    sink handling of target-independent machine instrs (other
    than DEBUG_VALUE :(  ) into the target indep AsmPrinter.cpp
    file.   This allows elimination of the
    NO_ASM_WRITER_BOILERPLATE hack among other things.

    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

    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.

    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.

    Add an option to GVN to remove all partially redundant loads.  This is currently
    disabled by default.  This divides the existing load PRE code into 2 phases:
    first it checks that it is safe to move the load to each of the predecessors
    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.

    of objc message send was getting marked arm_apcscc, but the prototype

    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.

    MC/X86 AsmParser: Handle absolute memory operands correctly. We were doing
    something totally broken and parsing them as immediates, but the .td file also
    had the wrong match class so things sortof worked. Except, that is, that we
    would parse
      movl $0, %eax
    as
      movl 0, %eax
    Feel free to guess how well that worked.

    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

    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.

    Assign the ordering of SDNodes in a much less intrusive fashion. After the

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.

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.

    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.

    @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.

    instead of:

    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.

    Split tail duplication into a separate pass.  This is needed to avoid
    running tail duplication when doing branch folding for if-conversion, and
    we also want to be able to run tail duplication earlier to fix some
    reg alloc problems.  Move the CanFallThrough function from BranchFolding
    to MachineBasicBlock so that it can be shared by TailDuplication.

    Based on the testcase for pr3120, running on my MacPro with Xeon processors,
    it is definitely profitable to tail duplicate indirect branches for x86.
    This is likely to be true to various degrees for all modern x86 processors.

    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).

    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.

    Massive refactoring of NEON instructions. Separate opcode from data size specifier suffix, move \t up stream to instruction format, and fix more 80 column violations.
    This fixes the NEON asm printing so the "predicate" field is printed between the opcode and the data type suffix.

    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

    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.

    Add getFrameIndexReference() to TargetRegisterInfo, which allows targets to
    tell debug info which base register to use to reference a frame index on a
    per-index basis. This is useful, for example, in the presence of dynamic
    stack realignment when local variables are indexed via the stack pointer and
    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.

    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...

    Comparisons of identified objects with null in the default address
    space are not captures. And, comparisons of two pointers within the
    same identified object are not captures.

Author: Jim Grosbach <grosbach@apple.com>
Date:   Thu Nov 19 23:10:28 2009 +0000

    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.

    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

    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.

    4.2.4, 4.3.4, 4.4.2.

    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).

    Add TOOLALIAS makefile variable; this defines an alternate name for a program
    which the makefiles will create by symlinking the actual tool to.
     - For use by clang, where we want to make 'clang++' and alias for clang (which
       enables C++ support in the driver)

     - Not sure this is the best approach, alternative suggestions welcome!

    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

    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.

    We should also disable edge splitting under -O0, but that has to wait a bit.

    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.

    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*.

    Fix bug in -split-phi-edges.

    When splitting an edge after a machine basic block with fall-through, we
    forgot to insert a jump instruction. Fix this by calling updateTerminator() on
    the fall-through block when relevant.

    Also be more precise in PHIElimination::isLiveIn.

    The BasicBlock associated with a MachineBasicBlock does not necessarily
    correspond to the code in the MBB.

    Don't insert a new IR BasicBlock when splitting critical edges. We are not
    supposed to modify the IR during codegen, and we should be able to do just
    fine with a NULL BB.

    branch would be required.

Author: David Greene <greened@obbligato.org>
Date:   Thu Nov 12 20:55:29 2009 +0000

    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).

    Add a bool flag to StackObjects telling whether they reference spill

    Remove default argument values.  It's too easy to pass a wrong argument
    value when multiple arguments have default values.  Make everything
    explicit to trap bugs early.

    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.

    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.

    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.

     - Force NDEBUG on in any Release build. This drops the compile time to ~100s
       from ~600s, in Release mode.

     - This may just be a temporary workaround, I don't know the true nature of the
       gcc-4.2 compile time performance problem.

    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!

    takes decimated instructions and applies identities to them.  This
    is pretty minimal at this point, but I plan to pull some instcombine
    logic out into these and similar routines.

    The jump table was being generated before the end label for exception handling
    was generated. This caused code like this:

    ## The asm code for the function
            .section        __TEXT,__const
            .align  2

    Leh_func_end11:   ## <---now in the wrong section!

    The `Leh_func_end11' would then end up in the wrong section, causing the
    resulting EH frame information to be wrong:

    __ZL11CheckRightsjPKcbRbRP6NSData.eh:
        .set    Lset500eh,Leh_frame_end11-Leh_frame_begin11
        .long   Lset500eh  ; Length of Frame Information Entry
    Leh_frame_begin11:
        .long   Leh_frame_begin11-Leh_frame_common
        .long   Leh_func_begin11-.
        .set    Lset501eh,Leh_func_end11-Leh_func_begin11
        .long   Lset501eh                                   ; FDE address range
    `Lset501eh' is now something huge instead of the real value.

    The X86 back-end generates the jump table after the EH information is
    emitted. Do the same here.

    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.

    Add a 'zkill' script, which is more-or-less a fancy (although not necessarily
    very robust) version of killall. Because I like making shiny new wheels out of
    spare parts.

    For use by buildbots when people insist on making cc1 infinite loop. :)

    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.

    make instcombine only rewrite a chain of computation
    (eliminating some extends) if the new type of the
    computation is legal or if both the source and dest
    are illegal.  This prevents instcombine from changing big
    chains of computation into i64 on 32-bit targets for
    example.

    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.

    - Add TargetInstrInfo::isIdentical(). It's similar to MachineInstr::isIdentical
      except it doesn't care if the definitions' virtual registers differ. This is
      used by machine LICM and other MI passes to perform CSE.
    - 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.

    Also verify the condition that the PHI join source register is only used in
    the PHI join. Otherwise the coalescing is invalid.

    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.

    Give the JITResolver a direct pointer to its JITEmitter, and use that instead
    of going through the global TheJIT variable.  This makes it easier to use

    - 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.

commit e67ebab906b981bb9534cd7c68fda75cb5ff57c9
Author: Victor Hernandez <vhernandez@apple.com>

    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.

    Implement some new transforms for optimizing
    subtracts of two pointer to ints into the same vector.  This happens

    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.

    fix an IPSCCP bug I introduced when I changed IPSCCP to start working on
    functions that don't have local linkage.  Basically, we need to be more
    careful about propagating argument information to functions whose results
    we aren't tracking.  This fixes a miscompilation of
    LLVMCConfigurationEmitter.cpp when built with an llvm-gcc that has ipsccp
    enabled.

    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
    }

    CMake: Report an error if there is an unknown .cpp file in a source
    directory.

    This is useful in case someone who works with the config&make build
    system forgot to add a file to its CMakeLists.txt. Instead of
    obtaining undefined references at link time, cmake will complain at
    configure time on the first build after a svn update.

    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.

    Do not infer the target type for COPY_TO_REGCLASS from dest regclass, this won't work if it can contain several types. Require explicit result type for the node for now. This fixes PR5364.

    PS: It seems that blackfin usage of copy_to_regclass is completely bogus!

Author: Chris Lattner <sabre@nondot.org>
Date:   Sun Nov 1 20:41:59 2009 +0000

    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.

    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),

    generally undesirable to nuke blocks whose address is taken, even when
    we can, just unconditionally stop this xform.

    Revert 85678/85680.  The decision is to stay with the current form of
    indirectbr, thus we don't need "blockaddr(@func, null)".  Eliminate it
    for simplicity.

    blockaddress with a new blockaddress(@func, null) instead of a

    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).

    Optimize around the fact that pred_iterator is slow: instead of sorting
    PHI operands by the predecessor order, sort them by the order used by the
    first PHI in the block. This is still suffucient to expose duplicates.

    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

    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

    heuristic to place it nearest the stack pointer in that case, rather than
    nearest the frame pointer.

    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

    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.

    This problem was usually hidden because indvars transforms such induction
    variables into negations of canonical induction variables.

commit 9919ed02cbeac5498b21825ae4924b140784be08
Author: Evan Cheng <evan.cheng@apple.com>

    - 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.

    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]

    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.

    This address: PR 5277 (Program::Wait is unsafe to call from multiple threads).

    Note: If waitpid() turns out to be non-portable, we can add more autoconf magic, or look into
    another solution.

    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.

    instcombine but makes other clients of ConstantFoldInstruction

    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

    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).

    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

    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.

    Re-apply r84295, with fixes to how the loop "top" and "bottom" blocks are
    tracked. Instead of trying to manually keep track of these locations
    while doing complex modifications, just recompute them when they're needed.
    This fixes a bug in which the TopMBB and BotMBB were not correctly updated,
    leading to invalid transformations.

    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.

    only try to fold constantexpr operands when the worklist is first populated,
    don't bother every time going around the main worklist.  This speeds up a
    release-asserts opt -std-compile-opts on 403.gcc by about 4% (1.5s).  It
    seems to speed up the most expensive instances of instcombine by ~10%.

    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.

    Take advantage of TargetData when available; we know that the atomic intrinsics

    Make CodePlacementOpt align loops, rather than loop headers. The
    header is just the entry block to the loop, and it needn't be at
    the top of the loop in the code layout.

    Remove the code that suppressed loop alignment for outer loops,
    so that outer loops are aligned.

    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.

    More Neon clean-up: avoid the need for custom-lowering vld/st-lane intrinsics

    More bits of the ARM target assembler for llvm-mc to parse immediates.
    Also fixed a couple of coding style things that crept in.  And added more
    to the temporary hacked up ARMAsmParser::MatchInstruction() method for testing.

    Introduce new convenience methods for sign extending or
    truncating an SDValue (depending on whether the target
    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.

    Copy metadata when value is RAUW'd. It is debatable whether this is the right approach for custom metadata data in general. However, right now the only custom data user, "dbg", expects this behavior while FE is constructing llvm IR with debug info.

    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.

    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.

    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.

    LICM shouldn't sink/delete debug information. Fix this and add a testcase.
    For now the metadata of sinked/hoisted instructions is still wrong, but that'll
    be fixed when instructions will have debug metadata directly attached.

    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).

    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).

    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.

    tried the specific case in SPASS.

    bugfix. The target may use virtual registers that aren't tracked for re-use but are allocated by the scavenger. The re-use algorithm needs to watch for that.

    In instcombine's debug output, avoid printing ADD for instructions that are
    already on the worklist, and print Visited when an instruction is about to be
    visited.  Net, on one input, this reduced the output size by at least 9x.

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.

    strength reduce a ton of type equality tests to check the typeid (Through
    the new predicates I added) instead of going through a context and doing a

    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
    allocations. e.g. ARM::LDRD require the two definitions to be allocated
    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.

    For Darwin, emit all the text section directives together before the dwarf
    section directives.  This causes the assembler to put the text sections at

    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.

    Make ARM and Thumb2 32-bit immediate materialization into a single 32-bit pseudo
    instruction. This makes it re-materializable.

    Thumb2 will split it back out into two instructions so IT pass will generate the
    right mask. Also, this expose opportunies to optimize the movw to a 16-bit move.

    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.

    Fix SCEVExpander's canonical addrec expansion code to work on loops that
    aren't in canonical loop-simplify form, since it doesn't itself depend
    on LoopSimplify. This means handling loops without preheaders and loops
    with multiple backedges.

    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).

    Fix MachineSink to be able to sink instructions that use physical registers
    which have no defs anywhere in the function. In particular, this fixes sinking
    of instructions that reference RIP on x86-64, which is currently being modeled
    as a register.

    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.

    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 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.

    Give MachineMemOperand an operator<<, factoring out code from
    two different places for printing MachineMemOperands.

    Drop the virtual from Value::dump and instead give Value a
    protected virtual hook that can be overridden by subclasses
    to implement custom printing. This lets printing be more
    consistent, and simplifies printing of PseudoSourceValue
    values.

    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.

    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.

    Clean up spill weight computation. Also some changes to give loop induction
    variable increment / decrement slighter high priority.

    This has major impact on some micro-benchmarks. On MultiSource/Applications
    and spec tests, it's a minor win. It also reduce 256.bzip instruction count
    by 8%, 55 on 164.gzip on i386 / Darwin.

    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

    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);
    }

    Move CoerceAvailableValueToLoadType earlier in GVN.cpp.  Hook it up

    enhance GVN to forward substitute a stored value to a load
    (and load -> load) when the base pointers must alias but when
    they are different types.  This occurs very very frequently in
    176.gcc and other code that uses bitfields a lot.

    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
    output operands.  Don't do this.  PR 4964.

    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

    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.

    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.

    The patterns will stay blank because ADD reg, reg

    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
    disassembler).

    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,
    which means it could appear following a noreturn call even when
    that is not a stub, confusing X86CompilationCallback2.  PR 4929.

    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.

    Don't pull a load through a callseq_start if the load's chain
    has multiple uses, as one of the other uses may be on a path
    to a different node above the callseq_start, because that
    leads to a cyclic graph. This problem is exposed when
    -combiner-global-alias-analysis is used. This fixes PR4880.

    Added the first bits of the ARM target assembler to llvm-mc.  For now it only
    parses the .word directive as 4 bytes and ARMAsmParser::ParseInstruction will
    give an error is called.  Broke out the test of the .word directive into two
    different test cases, one for x86 and one for arm.

    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.

    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,
    this means that it can only lower one MachineInstr to one MCInst.  To
    make this fly, we need to pull out handling of MO_GOT_ABSOLUTE_ADDRESS
    (which generates an implicit label) out of X86MCInstLower.

    split MachineInstr -> MCInst lowering into its own class (not
    being embedded into X86ATTAsmPrinter).  This still depends heavily
    on X86ATTAsmPrinter, but this is a step in the right direction.

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.

    change FnStubs from being a StringMap<std::string> to being a much
    more efficient SmallPtrSet<MCSymbol*>.  This eliminates string
    craziness and fixes CodeGen/X86/darwin-quote.ll with the new asmprinter.

    Codegen is producing stubs in a nondeterminstic order, but it was doing
    this before anyway.

    reimplement X86ATTAsmPrinter::GetGlobalAddressSymbol in terms of
    Mangler::getNameWithPrefix.  In addition to avoiding some over

    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.

    and use it in ConstantFold.cpp to check whether there are any mis-behaved
    indices.

    Revert part of my r81424 patch. I removed what looked like superfluous padding
    from the exception tables. However, Duncan explained why it's a can of worms to
    do it the GCC way. I went back to doing it the LLVM way and added Duncan's
    explanation so that I don't do this again in the future.

    Don't hardcode the TType format size. In fact, rework the code so that it's more
    like what GCC outputs. The mysterious code to insert padding wasn't in GCC at
    all. I modified the TType base offset code to calculate the offset like GCC
    does, though.

    TypeInfoSize should be the size of the TType format encoding (at least that's
    what GCC thinks it should be).

    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.

    Fixed missing newline in debugEntry().
    Cleaned up assert messages. (assert(0 && Message) is still shown, but the message is printed before.)
    When verifiying loaded profiles the ProfileVerifier got confused when block was a setjmp target, this is checked now.
    When verifiying loaded profiles the ProfileVerifier got confused when block eventually reaching an exit(), this is checked now.

    change selectiondag to add the sign extended versions of immediate operands
    to instructions instead of zero extended ones.  This makes the asmprinter
    print signed values more consistently.  This apparently only really affects
    the X86 backend.

    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.

    Simplify from my last change. Assert1 is a macro that makes its caller return,
    so "Assert1(isa<>); cast<>" is a valid idiom.

    Actually check the PHI node's odd-numbered operands for BasicBlock-ness, like
    the comment said.

    Verify types. Invalid types can be constructed when assertions are off.

    Make the verifier more robust by avoiding unprotected cast<> calls. Notably,
    Assert1(isa<>); cast<> is not safe as Assert1 does not terminate the program.

    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

    Now that googletest can print ConstantRange, use EXPECT_EQ when testing for

    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.

    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

    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.

    Change PHINode::hasConstantValue to have a DominatorTree argument
    instead of a bool argument, and to do the dominator check itself.

    different formatting from the old asmprinter, but it should be
    semantically the same.  We used to get:

    	popl	%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).

    Added opaque 32-, 48-, and 80-bit memory operand types to the X86

    Fix PR4845: r77946 completely broke x86_64 Darwin (or any situation where the
    desired triplet is a sub-target, e.g. thumbv7 vs. arm host). Reverting the
    patch isn't quite right either since the previous behavior does not allow the
    triplet to be overridden with -march.

    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.

    Fix pr4843: When an instruction has multiple destination registers that are
    tied to different source registers, the TwoAddressInstructionPass needs to
    be smarter.  Change it to check before replacing a source register whether
    that source register is tied to a different destination register, and if so,
    defer handling it until a subsequent iteration.

    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.
