commit 4d555935ac5c77164d9af2494f470abdb542a434
Author: Duncan Sands <baldrick@free.fr>

    Tweak the way appendModuleInlineAsm works, so you aren't obliged
    to append a newline when using setModuleInlineAsm in case later
    someone calls appendModuleInlineAsm - make newline handling fully
    automatic.  In case anyone is wondering there is only one user of
    appendModuleInlineAsm: the dragonegg plugin.

    Regenerate configure.

    With the previous cleanup to configure.ac, configure is now only 393k, instead of 1.1M!

    git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94535 91177308-0d34-0410-b5e6-96231b3b80d8

Date:   Tue Jan 26 08:48:04 2010 +0000

    Remove unneeded checks from configure.ac.

    HAVE_{BI,STD,FWD}_ITERATOR and HAVE_NAMESPACES were not used in the code.
    bison and flex are no longer used.
    CAN_DLOPEN_SELF was never used either.
    AC_PROG_LIBTOOL is not needed since we don't use libtool, we only need the
    libltdl checks for dlopen.
    Add check for AR, it used to be done by AC_PROG_LIBTOOL.
    AC_TYPE_SIGNAL is deprecated, follow autoupdate's suggestion and replace with
    void.
    Remove unused m4 files.
    Configure can now be generated using autoconf 2.65 too, without any warnings!

Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Jan 26 06:53:37 2010 +0000

    eliminate the TargetLowering::UsesGlobalOffsetTable bool, which is
    subsumed by TargetLowering::getJumpTableEncoding().  Change uses of
    it to be more specific.

    Now that printPICJumpTableSetLabel is not overloaded,
    inline it into its only caller, allowing us to simplify it
    and hoist bits out of the loop.

    git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94528 91177308-0d34-0410-b5e6-96231b3b80d8

    Move getJTISymbol from MachineJumpTableInfo to MachineFunction,
    which is more convenient, and change getPICJumpTableRelocBaseExpr
    to take a MachineFunction to match.

    Next, move the X86 code that create a PICBase symbol to
    X86TargetLowering::getPICBaseSymbol from
    X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific
    library.  This eliminates a 'gross hack', and allows us to
    implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now
    calls it.

    This in turn allows us to eliminate the
    X86AsmPrinter::printPICJumpTableSetLabel method, which was the
    only overload of printPICJumpTableSetLabel.

    simplify asmprinter: only emit .set directives when entries have
    EK_LabelDifference32 kind and the target has .set support.  Simplify
    X86AsmPrinter::printPICJumpTableSetLabel to make use of recent helpers.

    rename printPICJumpTableEntry -> EmitJumpTableEntry,
    make it private and non-virtual.  It handles the non-pic
    case too, so just use it, simplifying EmitJumpTableInfo.

commit 5ed376c1534bd482cae00ca58365945a5c595d06
Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Jan 26 05:02:42 2010 +0000

    implement X86 @GOTOFF jump table entries with the new EK_Custom32
    jump table entry kind, instead of overloading
    AsmPrinter::printPICJumpTableEntry.

    This has a pretty horrible and inefficient FIXME around how @GOTOFF
    is currently smashed into the mcsymbol name, but otherwise this is
    much cleaner.

    New PBQP solver.

    * Fixed a reduction bug which occasionally led to infinite-cost (invalid)
      register allocation solutions despite the existence finite-cost solutions.
    * Significantly reduced memory usage (>50% reduction).
    * Simplified a lot of the solver code.

    Fix the the ceiling-division used in computing the MaxBECount so that it doesn't
    have trouble with an intermediate add overflowing. Also, be more conservative
    about the case where the induction variable in an SLT loop exit can step past
    the RHS of the SLT and overflow in a single step.

    Make getSignedRange more aggressive, to recover for some common cases which
    the above fixes pessimized.

    This addresses rdar://7561161.

    don't bother setting the AsmPrinter::MF ivar, now that
    AsmPrinter::SetupMachineFunction sets it.  Note that systemz
    and msp430 didn't.  Yay for reduced inconsistency! :)

    make MachineFunction keep track of its ID and make

    AsmPrinter do both.  Have the AsmPrinter::SetupMachineFunction
    method set the 'AsmPrinter::MF' variable.

commit f64ffc4e7521176024d0c53f2e3a702c6de98133
Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Jan 25 23:26:13 2010 +0000

    Rearrange handling of jump tables.  Highlights:
    1. MachineJumpTableInfo is now created lazily for a function the first time
       it actually makes a jump table instead of for every function.
    2. The encoding of jump table entries is now described by the
       MachineJumpTableInfo::JTEntryKind enum.  This enum is determined by the
       TLI::getJumpTableEncoding() hook, instead of by lots of code scattered
       throughout the compiler that "knows" that jump table entries are always
       32-bits in pic mode (for example).
    3. The size and alignment of jump table entries is now calculated based on
       their kind, instead of at machinefunction creation time.

    Future work includes using the EntryKind in more places in the compiler,
    eliminating other logic that "knows" the layout of jump tables in various
    situations.

    Change Value::getUnderlyingObject to have the MaxLookup value specified as a
    parameter with a default value, instead of just hardcoding it in the
    implementation.  The limit of MaxLookup = 6 was introduced in r69151 to fix
    a performance problem with O(n^2) behavior in instcombine, but the scalarrepl
    pass is relying on getUnderlyingObject to go all the way back to an AllocaInst.
    Making the limit part of the method signature makes it clear that by default
    the result is limited and should help avoid similar problems in the future.
    This fixes pr6126.

    linux/ppc does use alignment in bytes, not pow-2.  This fixes PR6129.
    It looks like linux/arm and linux/mips have the same setting, which

    investigate with the testcase in PR6129.

    Remove the '-disable-scheduling' flag and replace it with the 'source' option of
    the '-pre-RA-sched' flag. It actually makes more sense to do it this way. Also,
    keep track of the SDNode ordering by default. Eventually, we would like to make
    this ordering a way to break a "tie" in the scheduler. However, doing that now
    breaks the "CodeGen/X86/abi-isel.ll" test for 32-bit Linux.

    resolve a fixme: the "nonexecutable stack directive" is actually
    a .section.  Switch to it with SwitchSection.

    However, I think that this directive should be safe on any ELF target.

    Modified the register matcher function in AsmMatcher to
    be static.  Also made it possible for clients to get it
    and no other functions from ...GenAsmMatcher.inc by
    defining REGISTERS_ONLY before including GenAsmMatcher.inc.
    This sets the stage for target-specific lexers that can
    identify registers and return AsmToken::Register as
    appropriate.

    For blocks that are not loop headers, just print their loop depth and header BB.
    For loop headers, print Inner loop along with the other stuff so it doesn't take
    an extra line.  We now get stuff like this:

    LBB1_4:                                                     ## %land.end

            notb    %al
            testb   $1, %al
            jne     LBB1_8

    and:

    LBB1_6:                                                     ## %while.cond7
                                                                ## Inner Loop Header: Depth=3
                                                                ##     Inside Loop BB1_5 Depth 2
                                                                ##   Inside Loop BB1_1 Depth 1

    which still isn't great for loop headers, but is much less verbose.

    Add the ability for MCStreamer to emit comments on the same line as directives.
    Switch over the asm-verbose comment for double values to use it.  We now get:

    _x:
    	.long	343597384                                   ## double 1.231200e+02
    	.long	1079953326

    For example, note that the comment is on the same line as the .long.  Woo.

    Stop building RTTI information for *most* llvm libraries.  Notable
    missing ones are libsupport, libsystem and libvmcore.  libvmcore is
    currently blocked on bugpoint, which uses EH.  Once it stops using
    EH, we can switch it off.

    This #if 0's out 3 unit tests, because gtest requires RTTI information.
    Suggestions welcome on how to fix this.

    When inserting expressions for post-increment users which contain
    loop-variant components, adds must be inserted after the increment.
    Keep track of the increment position for this case, and insert
    these adds in the correct location.

    It turns out that this #include is needed because otherwise
    ValueMapper.cpp ends up calling an out of line
    __ZNK4llvm12PATypeHolder3getEv, which is a template and llvm-config
    determines arbitrarily to use the one in libipo.  This sucks, but
    keeping the #include is a reasonable workaround.

    Re-implement the main strength-reduction portion of LoopStrengthReduction.
    This new version is much more aggressive about doing "full" reduction in
    cases where it reduces register pressure, and also more aggressive about
    rewriting induction variables to count down (or up) to zero when doing so
    reduces register pressure.

    It currently uses fairly simplistic algorithms for finding reuse
    opportunities, but it introduces a new framework allows it to combine
    multiple strategies at once to form hybrid solutions, instead of doing
    all full-reduction or all base+index.

    When doing address-mode sinking, expand the base register first, rather
    than the scaled register. This makes it more likely that subsequent
    AddrModeMatcher queries will match the new address the same way as the
    old, instead of accidentally matching what had been the base register
    as the new scaled register, and then failing to match the scaled register.
    This fixes some problems with address-mode sinking multiple muls into a
    block, which will be a lot more common with some upcoming
    LoopStrengthReduction changes.

Date:   Tue Jan 19 21:55:32 2010 +0000

    Add a new helper function to IVUsers for returning the "canonical"
    form of an expression. This is the expression without the
    post-increment adjustment made, which is useful in determining
    which registers will be used by the expansion.

    For aligned load/store instructions, it's only required to know whether a
    function can support dynamic stack realignment. That's a much easier question
    to answer at instruction selection stage than whether the function actually
    will have dynamic alignment prologue. This allows the removal of the
    stack alignment heuristic pass, and improves code quality for cases where
    the heuristic would result in dynamic alignment code being generated when
    it was not strictly necessary.

    The change in r90189 adds a link in a directory outside the iPhone platform
    directory when building the llvmCore_Embedded project.  Fix this by putting
    the iPhone platform directory into DEST_DIR instead of DEST_ROOT.  I also
    noticed what appears to be an unintentional use of DEVELOPER_BIN instead of
    DEVELOPER_DIR, so I fixed that and changed to use DEVELOPER_DIR in some places
    that were hardcoded to "Developer".  Finally, the other changes here allowed
    some refactoring and simplification, which I have done.

    Now that we have everything nicely factored (e.g. asmprinter is not
    doing global variable classification anymore) and hookized, sink almost
    all target targets global variable emission code into AsmPrinter and out
    of each target.

    Some notes:

    1. PIC16 does completely custom and crazy stuff, so it is not changed.
    2. XCore has some custom handling for extra directives.  I'll look at it next.
    3. This switches linux/ppc to use .globl instead of .global.  If .globl is
       actually wrong, let me know and I'll fix it.
    4. This makes linux/ppc get a lot of random cases right which were obviously
       wrong before, it is probably now a bit healthier.
    5. Blackfin will probably start getting .comm and other things that it didn't
       before.  If this is undesirable, it should explicitly opt out of these
       things by clearing the relevant fields of MCAsmInfo.

    This leads to a nice diffstat:

Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Jan 19 04:39:15 2010 +0000

    hoist handling of external globals and special globals up to common code.
    This makes a similar code dead in all the other targets, I'll clean it up
    in a bit.

    This also moves handling of lcomm up before acquisition of a section,
    since lcomm never needs a section.

    Fix a crash in scalarrepl for memcpy/memmove where the source and destination
    are the same.  I had already fixed a similar problem where the source and
    destination were different bitcasts derived from the same alloca, but the
    previous fix still did not handle the case where both operands are exactly
    the same value.  Radar 7552893.

Date:   Tue Jan 19 03:06:01 2010 +0000

    fix a significant difference between llvm and gcc on ELF systems:
    GCC would put weak zero initialized mutable data in the .bss section,
    we would put it into a crasy '.gnu.linkonce.b.test,"aw",@nobits'
    section.  Fixing this will allow simplifications next up.

    introduce a section kind for common linkage.  Use this to slightly
    simplify and commonize some of the asmprinter logic for globals.

    This also avoids printing the MCSection for .zerofill, which broke

    Cleanup handling of .zerofill on darwin:

    1. TargetLoweringObjectFileMachO should decide if something
       goes in zerofill instead of having every target do it.
    2. TargetLoweringObjectFileMachO should assign said symbols to
       the right MCSection, the asmprinters should just emit to the
       right section.
    3. Since all zerofill stuff goes through mcstreamer anymore,
       MAI can have a bool "haszerofill" instead of having the textual
       directive to emit.

    Canonicalize -1 - x to ~x.

    Instcombine does this but apparently there are situations where this pattern will escape the optimizer and / or created by isel. Here is a case that's seen in JavaScriptCore:
      %t1 = sub i32 0, %a
      %t2 = add i32 %t1, -1
    The dag combiner pattern: ((c1-A)+c2) -> (c1+c2)-A
    will fold it to -1 - %a.

    only specifies the register class, which includes both hi-and-lo registers.

    Get MCSymbol out of the mangling business, and move all the logic
    to Mangler.  Now MCSymbol just decides whether to slap quotes around
    a symbol when printing it.

    This also fixes some weirdness where two MCSymbols could be created
    for the same symbol, if one needed to be mangled and got mangled to
    the other one.

    The Neon "vtst" instruction takes a suffix that is the element size alone --

    print/dumpWithDepth allows one to dump a DAG up to N levels deep.
    dump/printWithFullDepth prints the whole DAG, subject to a depth limit
    on 100 in the default case (to prevent infinite recursion).

    Have CannotYetSelect to a dumpWithFullDepth so it is clearer exactly
    what the non-matching DAG looks like.

    Change pre-regalloc tail duplication to only duplicate indirect branch blocks.
    The pre-regalloc pass caused some regressions in both compile time and
    performance of the generated code, and it did not improve performance, except
    for indirect branches.  I also moved the check for single-block loops to speed
    up the common case when running the taildup pass before reg allocation.

    Split the TargetAsmParser "ParseInstruction" interface in half:
    the new ParseInstruction method just parses and returns a list of
    target operands.  A new MatchInstruction interface is used to
    turn the operand list into an MCInst.

    This requires new/deleting all the operands, but it also gives
    targets the ability to use polymorphic operands if they want to.

    Dwarf EH prepare needs to be run after SjLj prepare. Otherwise,
    catch info can get misplaced when a selector ends up more than one block
    removed from the parent invoke(s). This could happen when a landing pad is
    shared by multiple invokes and is also a target of a normal edge from
    elsewhere.

    ARM "l" constraint for inline asm means R0-R7, also for Thumb2.

    This is consistent with llvm-gcc's arm/constraints.md.

    mode.

    Don't fold insufficiently aligned ldr/str into ldm/stm instructions.

    An unaligned ldr causes a trap, and is then emulated by the kernel with
    awesome performance. The darwin kernel does not emulate unaligned ldm/stm
    Thumb2 instructions, so don't generate them.

    This fixes the miscompilation of Multisource/Applications/JM/lencod for Thumb2.

    Generating unaligned ldr/str pairs from a 16-bit aligned memcpy is probably
    also a bad idea, but that is beyond the scope of this patch.

commit dee74d4ab14c941d0003b8d95fa5e60b582e4ba9
Author: Bill Wendling <isanbard@gmail.com>

    When the visitSub method was split into visitSub and visitFSub, this xform was
    added to the FSub version. However, the original version of this xform guarded
    against doing this for floating point (!Op0->getType()->isFPOrFPVector()).

    This is causing LLVM to perform incorrect xforms for code like:

    void func(double *rhi, double *rlo, double xh, double xl, double yh, double yl){
      double mh, ml;
      double c = 134217729.0;
      double up, u1, u2, vp, v1, v2;

      up = xh*c;
      u1 = (xh - up) + up;
      u2 = xh - u1;

      vp = yh*c;
      v1 = (yh - vp) + vp;
      v2 = yh - v1;

      mh = xh*yh;
      ml = (((u1*v1 - mh) + (u1*v2)) + (u2*v1)) + (u2*v2);
      ml += xh*yl + xl*yh;

      *rhi = mh + ml;
      *rlo = (mh - (*rhi)) + ml;
    }

    The last line was optimized away, but rl is intended to be the difference
    between the infinitely precise result of mh + ml and after it has been rounded
    to double precision.

    escape the quotes.

    change Mangler::makeNameProper to return its result in a SmallVector
    instead of returning it in an std::string.  Based on this change:

    1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
    2. Change a bunch of targets to call makeNameProper with a smallstring,
       making several of them *much* more efficient.
    3. Rewrite Mangler::makeNameProper to not build names and then prepend
       prefixes, not use temporary std::strings, and to avoid other crimes.

    It was only being used by instructions with the t_addrmode_sp addressing mode,
    and that is pattern matched in a way that guarantees SP is used. There is
    never any register allocation done from this class.

    Add a quick pass to optimize sign / zero extension instructions. For targets where the pre-extension values are available in the subreg of the result of the extension, replace the uses of the pre-extension value with the result + extract_subreg.

    For now, this pass is fairly conservative. It only perform the replacement when both the pre- and post- extension values are used in the block. It will miss cases where the post-extension values are live, but not used.

    1) Use the new SimplifyInstructionsInBlock routine instead of the copy
    in JT.

    2) When cloning blocks for PHI or xor conditions, use
    instsimplify to simplify the code as we go.  This allows us to
    squish common cases early in JT which opens up opportunities for
    subsequent iterations, and allows it to completely simplify the
    testcase.

    Add TargetInstrInfo::isCoalescableInstr. It returns true if the specified
    instruction is copy like where the source and destination registers can
    overlap. This is to be used by the coalescable to coalesce the source and
    destination registers of instructions like X86::MOVSX64rr32. Apparently
    some crazy people believe the coalescer is too simple.

    Reimplement getToken and SplitString as "StringRef helper functions"

    - getToken is modeled after StringRef::split but it can split on multiple
      separator chars and skips leading seperators.
    - SplitString is a StringRef::split variant for more than 2 elements with the
      same behaviour as getToken.

    instead of:

            movl    %edi, %eax

Date:   Mon Jan 11 04:05:13 2010 +0000

    Extend CanEvaluateZExtd to handle and/or/xor more aggressively in the
    BitsToClear case.  This allows it to promote expressions which have an
    and/or/xor after the lshr, promoting cases like test2 (from PR4216)
    and test3 (random extample extracted from a spec benchmark).

    clang now compiles the code in PR4216 into:

    _test_bitfield:                                             ## @test_bitfield
    	movl	%edi, %eax
    	orl	$194, %eax
    	movl	$4294902010, %ecx
    	andq	%rax, %rcx
    	orl	$32768, %edi
    	andq	$39936, %rdi
    	movq	%rdi, %rax
    	orq	%rcx, %rax
    	ret

    instead of:

    _test_bitfield:                                             ## @test_bitfield
    	movl	%edi, %eax
    	orl	$194, %eax
    	movl	$4294902010, %ecx
    	andq	%rax, %rcx
    	shrl	$8, %edi
    	orl	$128, %edi
    	shlq	$8, %rdi
    	andq	$39936, %rdi
    	movq	%rdi, %rax
    	orq	%rcx, %rax
    	ret

    which is still not great, but is progress.

    teach zext optimization how to deal with truncs that don't come from

    mode:

    _test_bitfield:                                             ## @test_bitfield

    two changes:
    1) don't try to optimize a sext or zext that is only used by a trunc, let
       the trunc get optimized first.  This avoids some pointless effort in
       some common cases since instcombine scans down a block in the first pass.
    2) Change the cost model for zext elimination to consider an 'and' cheaper
       than a zext.  This allows us to do it more aggressively, and for the next
       patch to simplify the code quite a bit.

    Fixed linking of modules containing aliases to constant bitcasts.  Existing behaviour first tried to replace the aliases with the global that they aliased (rather than the bitcast), causing a crash on an assert because the types didn't match.  When this was fixed, it then did the same thing creating the new alias (creating an alias with a different type to its aliasee).

    Linking modules containing aliases to GEPs is still not quite right.  GEPs that are equivalent to bitcasts will be replaced by bitcasts, GEPs that are not will just break.  Aliases to GEPs that are not equivalent to bitcasts are horribly broken anyway (it might be worth adding an assert when creating the alias to prevent these being created; they just cause problems later).

    Revert an earlier change to SIGN_EXTEND_INREG for vectors. The VTSDNode
    really does need to be a vector type, because

    if the result is smaller than a byte, this shift is invalid.

    After further thought revert the patch to make fast-isel avoid
    putting relocations into the constant pool - this isn't needed
    for correctness and in the rare occasion it happens would pull
    us out of fast isel for the block.

    If fast-isel application startup time ever becomes an issue we
    can add better support for these addresses instead of bailing.

    Fix DFS number calculation for postdominators

    The DFS number calculation for postdominators was broken. In the case of
    multiple exits that form the post dominator root nodes, do not iterate over
    all exits, but start from the virtual root node. Otherwise bbs, that are not
    post dominated by any exit but by the virtual root node, will never be assigned
    a DFS number.

    now handles vectors, and you can't insertelement into a vector.  It

    Teach dag combine to fold the following transformation more aggressively:
    (OP (trunc x), (trunc y)) -> (trunc (OP x, y))

    Unfortunately this simple change causes dag combine to infinite looping. The problem is the shrink demanded ops optimization tend to canonicalize expressions in the opposite manner. That is badness. This patch disable those optimizations in dag combine but instead it is done as a late pass in sdisel.

    This also exposes some deficiencies in dag combine and x86 setcc / brcond lowering. Teach them to look pass ISD::TRUNCATE in various places.

    Partially address a README by having functionattrs consider calls to
    memcpy, memset and other intrinsics that only access their arguments
    to be readnone if the intrinsic's arguments all point to local memory.
    This improves the testcase in the README to readonly, but it could in
    theory be made readnone, however this would involve more sophisticated
    analysis that looks through the memcpy.

    Teach instcombine's sext elimination logic to be more aggressive.
    Previously, instcombine would only promote an expression tree to
    the larger type if doing so eliminated two casts.  This is because
    a need to manually do the sign extend after the promoted expression
    tree with two shifts.  Now, we keep track of whether the result of
    the computation is going to be properly sign extended already.  If
    so, we can unconditionally promote the expression, which allows us
    to zap more sext's.

    This implements rdar://6598839 (aka gcc pr38751)

    Remove livein checks from machine code verifier.

    A phi operand that is implicitly defined in a predecessor becomes an undefined
    register after phi elimination. This causes a lot of false positives when the
    verifier is checking if live-in registers are live-out from all predecessors.

    Removing the verifier checks seems like a better solution than insisting on
    IMPLICIT_DEF instructions in predecessor blocks.

    Add a SmallBitVector class, which mimics BitVector but uses only
    a single pointer (PointerIntPair) member. In "small" mode, the
    pointer field is reinterpreted as a set of bits. In "large" mode,
    the pointer points to a heap-allocated object.

    Also, give BitVector empty and swap functions.

    And, add some simple unittests for BitVector and SmallBitVector.

Author: Dan Gohman <gohman@apple.com>
Date:   Tue Jan 5 01:24:18 2010 +0000

    Change SelectCode's argument from SDValue to SDNode *, to make it more
    clear what information these functions are actually using.

    This is also a micro-optimization, as passing a SDNode * around is
    simpler than passing a { SDNode *, int } by value or reference.

    Truncate GEP indexes larger than the pointer size down to pointer size
    when doing this transform if the GEP is not inbounds.  No testcase because
    it is very difficult to trigger this: instcombine already canonicalizes
    GEP indices to pointer size, so it relies specific permutations of the
    instcombine worklist.

    Thanks to Duncan for pointing this possible problem out.

    Teach the table lookup optimization to generate range compares
    when a consequtive sequence of elements all satisfies the
    predicate.  Like the double compare case, this generates better
    code than the magic constant case and generalizes to more than
    32/64 element array lookups.

    Here are some examples where it triggers.  From 403.gcc, most
    accesses to the rtx_class array are handled, e.g.:

    @rtx_class = constant [153 x i8] c"xxxxxmmmmmmmmxxxxxxxxxxxxmxxxxxxiiixxxxxxxxxxxxxxxxxxxooxooooooxxoooooox3x2c21c2222ccc122222ccccaaaaaa<<<<<<<<<<<<<<<<<<111111111111bbooxxxxxxxxxxcc2211x", align 32 ; <[153 x i8]*> [#uses=547]
       %142 = icmp eq i8 %141, 105
    @rtx_class = constant [153 x i8] c"xxxxxmmmmmmmmxxxxxxxxxxxxmxxxxxxiiixxxxxxxxxxxxxxxxxxxooxooooooxxoooooox3x2c21c2222ccc122222ccccaaaaaa<<<<<<<<<<<<<<<<<<111111111111bbooxxxxxxxxxxcc2211x", align 32 ; <[153 x i8]*> [#uses=543]
    	   %165 = icmp eq i8 %164, 60

    Also, most of the 59-element arrays (mode_class/rid_to_yy, etc)
    optimized before are actually range compares.  This lets 32-bit
    machines optimize them.

    400.perlbmk has stuff like this:

    400.perlbmk: PL_regkind, even for 32-bit:
    @PL_regkind = constant [62 x i8] c"\00\00\02\02\02\06\06\06\06\09\09\0B\0B\0D\0E\0E\0E\11\12\12\14\14\16\16\18\18\1A\1A\1C\1C\1E\1F !!!$$&'((((,-.///88886789:;8$", align 32 ; <[62 x i8]*> [#uses=4]
    	   %811 = icmp ne i8 %810, 33

    @PL_utf8skip = constant [256 x i8] c"\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\01\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\02\03\03\03\03\03\03\03\03\03\03\03\03\03\03\03\03\04\04\04\04\04\04\04\04\05\05\05\05\06\06\07\0D", align 32 ; <[256 x i8]*> [#uses=94]
    	   %12 = icmp ult i8 %10, 2

    etc.

    Generalize the previous xform to handle cases where exactly
    two elements match or don't match with two comparisons.  For
    example, the testcase compiles into:

    define i1 @test5(i32 %X) {
      %1 = icmp eq i32 %X, 2                          ; <i1> [#uses=1]
      %2 = icmp eq i32 %X, 7                          ; <i1> [#uses=1]
      %R = or i1 %1, %2                               ; <i1> [#uses=1]
      ret i1 %R
    }

    This generalizes the previous xforms when the array is larger than
    64 elements (and this case matches) and generates better code for
    cases where it overlaps with the magic bitshift case.

    This generalizes more cases than you might expect.  For example,
    400.perlbmk has:

    @PL_utf8skip = constant [256 x i8] c"\01\01\01\...
    %15 = icmp ult i8 %7, 7

    403.gcc has:
    @rid_to_yy = internal constant [114 x i16] [i16 259, i16 260, ...
    %18 = icmp eq i16 %16, 295

    and xalancbmk has a bunch of examples, such as
    _ZN11xercesc_2_5L15gCombiningCharsE and _ZN11xercesc_2_5L10gBaseCharsE.

    enhance the compare/load/index optimization to work on *any* load
    from a global with 32/64 elements or less (depending on whether
    i64 is native on the target), generating a bitshift idiom to
    determine the result.  For example, on test4 we produce:

    define i1 @test4(i32 %X) {
      %1 = lshr i32 933, %X                           ; <i32> [#uses=1]
      %2 = and i32 %1, 1                              ; <i32> [#uses=1]
      %R = icmp ne i32 %2, 0                          ; <i1> [#uses=1]
      ret i1 %R
    }

    This triggers in a number of interesting cases, for example, here's an
    fp case:
    @A.3255 = internal constant [4 x double] [double 4.100000e+00, double -3.900000e+00, double -1.000000e+00, double 1.000000e+00], align 32 ; <[4 x double]*> [#uses=7]
    ...
    	   %7 = fcmp olt double %3, 0.000000e+00

    In this case we make the slen2_tab global dead, which is nice:
    @slen2_tab = internal constant [16 x i32] [i32 0, i32 1, i32 2, i32 3, i32 0, i32 1, i32 2, i32 3, i32 1, i32 2, i32 3, i32 1, i32 2, i32 3, i32 2, i32 3], align 32 ; <[16 x i32]*> [#uses=1]
    ...
    	   %204 = icmp eq i32 %46, 0

    Perl has a bunch of these, also on the 'Perl_regkind' array:
    @Perl_yygindex = internal constant [51 x i16] [i16 0, i16 0, i16 0, i16 0, i16 374, i16 351, i16 0, i16 -12, i16 0, i16 946, i16 413, i16 -83, i16 0, i16 0, i16 0, i16 -311, i16 -13, i16 4007, i16 2893, i16 0, i16 0, i16 0, i16 0, i16 0, i16 372, i16 -8, i16 0, i16 0, i16 246, i16 -131, i16 43, i16 86, i16 208, i16 -45, i16 -169, i16 987, i16 0, i16 0, i16 0, i16 0, i16 308, i16 0, i16 -271, i16 0, i16 0, i16 0, i16 0, i16 0, i16 0, i16 0, i16 0], align 32 ; <[51 x i16]*> [#uses=1]
    ...
      %1364 = icmp eq i16 %1361, 0

    186.crafty really likes this on 64-bit machines, because it triggers on a bunch of globals like this:
    @white_outpost = internal constant [64 x i8] c"\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\02\02\00\00\00\00\00\04\05\05\04\00\00\00\00\03\06\06\03\00\00\00\00\00\01\01\00\00\00\00\00\00\00\00\00\00\00", align 32 ; <[64 x i8]*> [#uses=2]

    However the big winner is 403.gcc, which triggers hundreds of times, eliminating all the accesses to the 57-element arrays 'mode_class', mode_unit_size, mode_bitsize, regclass_map, etc.

    go 64-bit machines :)

    Teach instcombine to fold compares of loads from constant
    arrays with variable indices into a comparison of the index
    with a constant.  The most common occurrence of this that
    I see by far is stuff like:

    if ("foobar"[i] == '\0') ...

    which we compile into: if (i == 6), saving a load and
    materialization of the global address.  This also exposes
    loop trip count information to later passes in many cases.

    This triggers hundreds of times in xalancbmk, which is where I first
    noticed it, but it also triggers in many other apps.  Here are a few
    interesting ones from various apps:

    This improves but doesn't complete fix 483.xalancbmk because llvm-gcc
    does this xform in GCC's "fold" routine as well.  Clang++ will do
    better I guess.

    Teach codegen to lower llvm.powi to an efficient (but not optimal)
    multiply sequence when the power is a constant integer.  Before, our
    codegen for std::pow(.., int) always turned into a libcall, which was
    really inefficient.

    This should also make many gfortran programs happier I'd imagine.

    When factoring multiply expressions across adds, factor both
    positive and negative forms of constants together.  This
    allows us to compile:

    int foo(int x, int y) {
        return (x-y) + (x-y) + (x-y);
    }

    into:

    _foo:                                                       ## @foo
    	subl	%esi, %edi
    	leal	(%rdi,%rdi,2), %eax
    	ret

    instead of (where the 3 and -3 were not factored):

    _foo:
            imull   $-3, 8(%esp), %ecx
            imull   $3, 4(%esp), %eax
            addl    %ecx, %eax
            ret

    this started out as:
        movl    12(%ebp), %ecx
        imull   $3, 8(%ebp), %eax
        subl    %ecx, %eax
        subl    %ecx, %eax
        subl    %ecx, %eax
        ret

    This comes from PR5359.

    reuse negates where possible instead of always creating them from scratch.
    This allows us to optimize test12 into:

    define i32 @test12(i32 %X) {
      %factor = mul i32 %X, -3                        ; <i32> [#uses=1]

      ret i32 %Z
    }

    instead of:

    define i32 @test12(i32 %X) {
      %Y = sub i32 6, %X                              ; <i32> [#uses=1]

    Optimize MDNode to coallocate the operand list immediately
    after the MDNode in memory.  This eliminates the operands
    pointer and saves a new[] per node.

    Note that the code in DIDerivedType::replaceAllUsesWith is wrong
    and quite scary.  A MDNode should not be RAUW'd with something
    else: this changes all uses of the mdnode, which may not be debug
    info related!  Debug info should use something non-mdnode for
    declarations.

    When doing v1->RAUW(v2), don't do anything to metadata.  We don't know
    why one was replaced with the other.  Even in the specific case of
    debug information, it doesn't make sense to transfer the location over,
    this will just result in jumbled loc info.

    add a layer of accessors around the Value::SubClassData member, and use
    a convention (shadowing the setter with private forwarding function) to
    prevent subclasses from accidentally using it.

    This exposed some bogosity in ConstantExprs, which was propaging the
    opcode of the constant expr into the NUW/NSW/Exact field in the
    getWithOperands/getWithOperandReplaced methods.

    This is a major cleanup of the instruction metadata interfaces that
    I asked Devang to do back on Sep 27.  Instead of going through the
    MetadataContext class with methods like getMD() and getMDs(), just
    ask the instruction directly for its metadata with getMetadata()
    and getAllMetadata().

    This includes a variety of other fixes and improvements: previously
    all Value*'s were bloated because the HasMetadata bit was thrown into
    value, adding a 9th bit to a byte.  Now this is properly sunk down to
    the Instruction class (the only place where it makes sense) and it
    will be folded away somewhere soon.

    This also fixes some confusion in getMDs and its clients about
    whether the returned list is indexed by the MDID or densely packed.
    This is now returned sorted and densely packed and the comments make
    this clear.

    This introduces a number of fixme's which I'll follow up on.

Date:   Fri Dec 11 23:47:40 2009 +0000

    Revise scalar replacement to be more flexible about handle bitcasts and GEPs.
    While scanning through the uses of an alloca, keep track of the current offset
    relative to the start of the alloca, and check memory references to see if
    the offset & size correspond to a component within the alloca.  This has the
    nice benefit of unifying much of the code from isSafeUseOfAllocation,
    isSafeElementUse, and isSafeUseOfBitCastedAllocation.  The code to rewrite
    the uses of a promoted alloca, after it is determined to be safe, is
    reorganized in the same way.

    Don't try to move a MBB into the fall-through position if it's a landing pad or
    branches only to a landing pad. Without this check, the compiler would go into
    an infinite loop because the branch to a landing pad is an "abnormal" edge which
    wasn't being taken into account.

    This is the meat of that fix:

      if (!PrevBB.canFallThrough() && !MBB->BranchesToLandingPad(MBB)) {

    The other stuff is simplification of the "branches to a landing pad" code.

    Simplify this class by removing the result cache.

    This change removes the DefaultConstructible
    and CopyAssignable constraints on the template
    parameter T (the first one).

    The second template parameter (R) is defaulted to be
    identical to the first and controls the result type.
    By specifying it to be (const T&) additionally the
    CopyConstructible constraint on T can be removed.

    This allows to use StringSwitch e.g. for llvm::Constant
    instances.

    Regarding the other review feedback regarding performance
    because of taking pointers, this class should be completely
    optimizable like before, since all methods are inline and
    the pointer dereferencing and result value caching should be
    possible behind the scenes by the "as-if" rule.

    A machine basic block may end in an unconditional branch, however it may have
    more than one successor. Normally, these extra successors are dead. However,
    some of them may branch to exception handling landing pads. If we remove those
    successors, then the landing pads could go away if all predecessors to it are
    removed. Before, it was checking if the direct successor was the landing
    pad. But it could be the result of jumping through multiple basic blocks to get
    to it. If we were to only check for the existence of an EH_LABEL in the basic
    block and not remove successors if it's in there, then it could stop actually
    dead basic blocks from being removed.

    Also attempt trivial coalescing for live intervals that end in a copy.

    The coalescer is supposed to clean these up, but when setting up parameters
    for a function call, there may be copies to physregs. If the defining
    instruction has been LICM'ed far away, the coalescer won't touch it.

    The register allocation hint does not always work - when the register
    allocator is backtracking, it clears the hints.

    This patch is more conservative than r90502, and does not break
    483.xalancbmk/i686. It still breaks the PowerPC bootstrap, so it is disabled
    by default, and can be enabled with the -trivial-coalesce-ends option.

    fix hte last remaining known (by me) phi translation bug.  When we reanalyze
    clobbers to forward pieces of large stores to small loads, we need to consider
    the properly phi translated pointer in the store block.

    Add a minor optimization: if we haven't changed the operands of an
    add, there is no need to scan the world to find the same add again.
    This invalidates the previous testcase, which wasn't wonderful anyway,
    because it needed a run of instcombine to permute the use-lists in
    just the right way to before GVN was run (so it was really fragile).
    Not a big loss.

    Added a new "splitting" spiller.

    When a call is placed to spill an interval this spiller will first try to
    break the interval up into its component values. Single value intervals and
    intervals which have already been split (or are the result of previous splits)
    are spilled by the default spiller.

    Splitting intervals as described above may improve the performance of generated
    code in some circumstances. This work is experimental however, and it still
    miscompiles many benchmarks. It's not recommended for general use yet.

    the code in GVN that tries to forward large loads to small

Author: Chris Lattner <sabre@nondot.org>
Date:   Wed Dec 9 01:59:31 2009 +0000

    Switch GVN and memdep to use PHITransAddr, which correctly handles
    phi translation of complex expressions like &A[i+1].  This has the
    following benefits:

    1. The phi translation logic is all contained in its own class with
       a strong interface and verification that it is self consistent.

    2. The logic is more correct than before.  Previously, if intermediate
       expressions got PHI translated, we'd miss the update and scan for
       the wrong pointers in predecessor blocks.  @phi_trans2 is a testcase
       for this.

    3. We have a lot less code in memdep.

    We can handle phi translation across blocks of things like @phi_trans3,
    which is pretty insane :).

    This patch should fix the miscompiles of 255.vortex, and I tested it
    with a bootstrap of llvm-gcc, llvm-test and dejagnu of course.

    Introduce the "@llvm.dbg.value" debug intrinsic.

    The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value.

    An example:
      call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2)
    Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0.

Author: Anton Korobeynikov <asl@math.spbu.ru>
Date:   Sun Dec 6 22:39:50 2009 +0000

    Dynamic stack realignment use of sp register as source/dest register
    in "bic sp, sp, #15" leads to unpredicatble behaviour in Thumb2 mode.
    Emit the following code instead:
    mov r4, sp
    bic r4, r4, #15
    mov sp, r4

    short x(short *A) {
      memset(A, 1, sizeof(*A)*100);
      return A[42];
    }

    to 'return 257' instead of doing the load.

    Also attempt trivial coalescing for live intervals that end in a copy.

    The coalescer is supposed to clean these up, but when setting up parameters
    for a function call, there may be copies to physregs. If the defining
    instruction has been LICM'ed far away, the coalescer won't touch it.

    The register allocation hint does not always work - when the register
    allocator is backtracking, it clears the hints.

    This patch takes care of a few more cases that r90163 missed.

    Fix ExpandShiftWithUnknownAmountBit, which was completely bogus.
    Pointed out by Javier Martinez (who also provided a patch).  Since
    this logic is not used on (for example) x86, I guess nobody noticed.
    Tested by generating SHL, SRL, SRA on various choices of i64 for all
    possible shift amounts, and comparing with gcc.  Since I did this on
    x86-32, I had to force the use of ExpandShiftWithUnknownAmountBit.
    What I'm saying here is that I don't have a testcase I can add to the
    repository.

    Recognize canonical forms of vector shuffles where the same vector is used for
    both source operands.  In the canonical form, the 2nd operand is changed to an
    undef and the shuffle mask is adjusted to only reference elements from the 1st
    operand.  Radar 7434842.

    This initial code is meant to convert TargetData to use an AbstractTypesUser so
    that it doesn't have dangling pointers when abstract types are resolved. This
    modifies it somewhat to address comments: making the "StructLayoutMap" an
    anonymous structure, calling "removeAbstractTypeUser" when appropriate, and
    adding asserts where helpful.

    Fix PR5391: support early clobber physical register def tied with a use (ewwww)
    - A valno should be set HasRedefByEC if there is an early clobber def in the middle of its live ranges. It should not be set if the def of the valno is defined by an early clobber.
    - If a physical register def is tied to an use and it's an early clobber, it just means the HasRedefByEC is set since it's still one continuous live range.
    - Add a couple of missing checks for HasRedefByEC in the coalescer. In general, it should not coalesce a vr with a physical register if the physical register has a early clobber def somewhere. This is overly conservative but that's the price for using such a nasty inline asm "feature".

    Move PHIElimination::isLiveOut method to LiveVariables.

    We want LiveVariables clients to use methods rather than accessing the
    getVarInfo data structure directly. That way it will be possible to change the

    Use CFG connectedness as a secondary sort key when deciding the order of copy coalescing.

    This means that well connected blocks are copy coalesced before the less connected blocks. Connected blocks are more difficult to
    coalesce because intervals are more complicated, so handling them first gives a greater chance of success.

    New virtual registers created for spill intervals should inherit allocation hints from the original register.

    This helps us avoid silly copies when rematting values that are copied to a physical register:

    leaq	_.str44(%rip), %rcx
    movq	%rcx, %rsi
    call	_strcmp

    becomes:

    leaq	_.str44(%rip), %rsi
    call	_strcmp

    The coalescer will not touch the movq because that would tie down the physical register.

    Reprioritize tests for tail duplication to be aggressive about indirect

    Remove isProfitableToDuplicateIndirectBranch target hook.  It is profitable
    for all the processors where I have tried it, and even when it might not help
    performance, the cost is quite low.  The opportunities for duplicating
    indirect branches are limited by other factors so code size does not change
    much due to tail duplicating indirect branches aggressively.

    This patch also simplifies graphs without any edgeSourceLabels e.g. the
    dominance trees.

    more. Update the syntax we're checking for and filecheckize it too.

    Fix a really nasty caching bug I introduced in memdep.  An entry
    was being added to the Result vector, but not being put in the
    cache.  This means that if the cache was reused wholesale for a
    later query that it would be missing this entry and we'd do an
    incorrect load elimination.

    Unfortunately, it's not really possible to write a useful
    testcase for this, but this unbreaks 255.vortex.

    enable code to handle un-phi-translatable cases more aggressively:
    if we don't have an address expression available in a predecessor,
    then model this as the value being clobbered at the end of the pred
    block instead of being modeled as a complete phi translation failure.
    This is important for PRE of loads because we want to see that the
    load is available in all but this predecessor, and complete phi
    translation failure results in not getting any information about
    predecessors.

    This doesn't do anything until I renable code insertion since PRE
    now sees that it is available in all but one predecessors, but can't
    insert the addressing in the predecessor that is missing it to
    eliminate the redundancy.

    void test(int N, double* G) {
      long j;
      G[1] = 1;
        for (j = 1; j < N - 1; j++)
            G[j+1] = G[j] + G[j+1];
    }

    to only do one load every iteration of the loop.

Date:   Fri Nov 27 16:37:41 2009 +0000

    fix PR5436 by making the 'simple' case of SRoA not promote out of range
    array indexes.  The "complex" case of SRoA still handles them, and correctly.

    This fixes a weirdness where we'd correctly avoid transforming A[0][42] if
    the 42 was too large, but we'd only do it if it was one gep, not two separate
    ones.

    While this test is testing a problem in the generic part of codegen,
    the problem only shows for msp430 and pic16 which is why it specifies
    them using -march.  But it is wrong to put such tests in CodeGen/Generic,
    since not everyone builds these targets.  Put a copy of the test in each
    of the target test directories.

    @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.

Author: Chris Lattner <sabre@nondot.org>
Date:   Thu Nov 26 16:26:43 2009 +0000

    Teach basicaa that x|c == x+c when the c bits of x are clear.  This
    allows us to compile the example in readme.txt into:

    LBB1_1:                                                     ## %bb
    	movl	4(%rdx,%rax), %ecx
    	movl	%ecx, %esi
    	imull	(%rdx,%rax), %esi
    	imull	%esi, %ecx
    	movl	%esi, 8(%rdx,%rax)
    	imull	%ecx, %esi
    	movl	%ecx, 12(%rdx,%rax)
    	movl	%esi, 16(%rdx,%rax)
    	imull	%ecx, %esi
    	movl	%esi, 20(%rdx,%rax)
    	addq	$16, %rax
    	cmpq	$4000, %rax
    	jne	LBB1_1

    instead of:

    LBB1_1:
    	movl	(%rdx,%rax), %ecx
    	imull	4(%rdx,%rax), %ecx
    	movl	%ecx, 8(%rdx,%rax)
    	imull	4(%rdx,%rax), %ecx
    	movl	%ecx, 12(%rdx,%rax)
    	imull	8(%rdx,%rax), %ecx
    	movl	%ecx, 16(%rdx,%rax)
    	imull	12(%rdx,%rax), %ecx
    	movl	%ecx, 20(%rdx,%rax)
    	addq	$16, %rax
    	cmpq	$4000, %rax
    	jne	LBB1_1

    GCC (4.2) doesn't seem to be able to eliminate the loads in this
    testcase either, it generates:

    L2:
    	movl	(%rdx), %eax
    	imull	4(%rdx), %eax
    	movl	%eax, 8(%rdx)
    	imull	4(%rdx), %eax
    	movl	%eax, 12(%rdx)
    	imull	8(%rdx), %eax
    	movl	%eax, 16(%rdx)
    	imull	12(%rdx), %eax
    	movl	%eax, 20(%rdx)
    	addl	$4, %ecx
    	addq	$16, %rdx
    	cmpl	$1002, %ecx
    	jne	L2

Author: Chris Lattner <sabre@nondot.org>
Date:   Thu Nov 26 02:17:34 2009 +0000

    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.

    Generalize DecomposeGEPExpression to exactly handle what Value::getUnderlyingObject does (when TD is around).  This allows us to avoid calling DecomposeGEPExpression unless the ultimate alias check we care about passes, speedup up BasicAA a bit.

Author: Chris Lattner <sabre@nondot.org>
Date:   Thu Nov 26 02:13:03 2009 +0000

    Implement a new DecomposeGEPExpression method, which decomposes a GEP into a list of scaled offsets.  Use this to eliminate some previous ad-hoc code which was subtly broken (it assumed all Constant*'s were non-zero, but strange constant express could be zero).

    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).

    * Move stub allocation inside the JITEmitter, instead of exposing a
    way for each TargetJITInfo subclass to allocate its own stubs. This
    means stubs aren't as exactly-sized anymore, but it lets us get rid of
    TargetJITInfo::emitFunctionStubAtAddr(), which lets ARM and PPC
    support the eager JIT, fixing http://llvm.org/PR4816.

    * Rename the JITEmitter's stub creation functions to describe the kind
    of stub they create. So far, all of them create lazy-compilation
    stubs, but they sometimes get used when far-call stubs are needed.
    Fixing http://llvm.org/PR5201 will involve fixing this.

    I forgot to update the prototype for LLVMBuildIntCast when correcting
    the body to not pass the name for the isSigned parameter.  However it
    seems that changing prototypes is a big-no-no, so here I revert the
    previous change and pass "true" for isSigned, meaning this always does
    a signed cast, which was the previous behaviour assuming the name was
    not NULL!  Some other C function needs to be introduced for the general
    case of signed or unsigned casts.  This hopefully unbreaks the ocaml
    binding.

    FileCheck, PR5239: Try to find the intended match on failures, but looking for a
    good nearby fuzzy match. Frequently the input is nearly correct, and just
    showing the user the a nearby sensible match is enough to diagnose the problem.
     - The "fuzzyness" is pretty simple and arbitrary, but worked on my three test
       cases. If you encounter problems, or places you think FileCheck should have
       guessed but didn't, please add test cases to PR5239.

    For example, previously FileCheck would report this:
    --
    t.cpp:21:55: error: expected string not found in input
    // CHECK: define void @_Z2f25f2_s1([[i64_i64_ty]] %a0)
                                                          ^
    <stdin>:19:30: note: scanning from here
    define void @_Z2f15f1_s1(%1) nounwind {
                                 ^
    <stdin>:19:30: note: with variable "i64_i64_ty" equal to "%0"
    --

    and now it also reports this:
    --
    <stdin>:27:1: note: possible intended match here
    define void @_Z2f25f2_s1(%0) nounwind {
    ^
    --

    which makes it clear that the CHECK just has an extra ' %a0' in it, without
    having to check the input.

    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.

Date:   Fri Nov 20 19:37:38 2009 +0000

    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.

    Move the handling of CommaSeparated options into ProvideOption.

    Makes '--comma-separated val1,val2' mean the same thing as
    '--comma-separated=val1,val2' (that is, 'val1' and 'val2' are not lumped
    together as 'val1,val2'). Also declutters the main loop a bit.

    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...

    which was an expensive checks failure due to a bug in the checking.  This
    patch in essence reverts the original fix for PR3393, and refixes it by a
    tweak to the way expensive checking is done.

    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.

    Add support for spreading register allocation.

    Add a -linearscan-skip-count argument (default to 0) that tells the
    allocator to remember the last N registers it allocated and skip them
    when looking for a register candidate.  This tends to spread out
    register usage and free up post-allocation scheduling at the cost of
    slightly more register pressure.  The primary benefit is the ability
    to backschedule reloads.

    This is turned off by default.

    Workaround PR5482, because all the gcc versions that I had were miscompiling StringRef:
    4.2.4, 4.3.4, 4.4.2.
    The workaround is to use a local min/max implementation that takes an integer
    param, and not a reference to integer param (like std::min does).

    Added a new Spiller implementation which wraps LiveIntervals::addIntervalsForSpills.
    All spiller calls in RegAllocLinearScan now go through the new Spiller interface.
    The "-new-spill-framework" command line option has been removed. To use the trivial in-place spiller you should now pass "-spiller=trivial -rewriter=trivial".
    (Note the trivial spiller/rewriter are only meant to serve as examples of the new in-place modification work. Enabling them will yield terrible, though hopefully functional, code).

    Don't require LiveVariables for PHIElimination. Enable critical edge splitting
    when LiveVariables is available.

    The -split-phi-edges is now gone, and so is the hack to disable it when using
    the local register allocator. The PHIElimination pass no longer has
    LiveVariables as a prerequisite - that is what broke the local allocator.
    Instead we do critical edge splitting when possible - that is when
    LiveVariables is available.

    Add a target hook to allow changing the tail duplication limit based on the
    contents of the block to be duplicated.  Use this for ARM Cortex A8/9 to
    be more aggressive tail duplicating indirect branches, since it makes it
    much more likely that they will be predicted in the branch target buffer.
    Testcase coming soon.

    The llvm-gcc front-end and the pass manager use two separate TargetData objects.
    This is probably not confined to *just* these two things.

    Anyway, the llvm-gcc front-end may look up the structure layout information for
    an abstract type. That information will be stored into a table with the FE's
    TD. Instruction combine can come along and also ask for information on that
    abstract type, but for a separate TD (the one associated with the pass manager).

    After the type is refined, the old structure layout information in the pass
    manager's TD file is out of date. If a new type is allocated in the same space
    as the old-unrefined type, then the structure type information in the pass
    manager's TD file will be wrong, but won't know it.

    Fix this by making the TD's structure type information an abstract type user.

    Remove a special case for tail merging that seems to be both broken and
    unnecessary.  It is broken because the "isIdenticalTo" check should be
    negated.  If that is fixed, this code causes the CodeGen/X86/tail-opts.ll
    test to fail, in the dont_merge_oddly function.  And, I confirmed that the
    regression is real -- the generated code is worse.  As far as I can tell,
    that tail-opts.ll test is checking for what this code is supposed to handle
    and we're doing the right thing anyway.

commit e233d8a0c6e61da9468080079d7b840a9ee05a72
Author: Jeffrey Yasskin <jyasskin@google.com>
Date:   Mon Nov 16 22:41:33 2009 +0000

    Make X86-64 in the Large model always emit 64-bit calls.
    The large code model is documented at
    http://www.x86-64.org/documentation/abi.pdf and says that calls should
    assume their target doesn't live within the 32-bit pc-relative offset
    that fits in the call instruction.

    To do this, we turn off the global-address->target-global-address
    conversion in X86TargetLowering::LowerCall(). The first attempt at
    this broke the lazy JIT because it can separate the movabs(imm->reg)
    from the actual call instruction. The lazy JIT receives the address of
    the movabs as a relocation and needs to record the return address from
    the call; and then when that call happens, it needs to patch the
    movabs with the newly-compiled target. We could thread the call
    instruction into the relocation and record the movabs<->call mapping
    explicitly, but that seems to require at least as much new
    complication in the code generator as this change.

    To fix this, we make lazy functions _always_ go through a call
    stub. You'd think we'd only have to force lazy calls through a stub on
    difficult platforms, but that turns out to break indirect calls
    through a function pointer. The right fix for that is to distinguish
    between calls and address-of operations on uncompiled functions, but
    that's complex enough to leave for someone else to do.

    Another attempt at this defined a new CALL64i pseudo-instruction,
    which expanded to a 2-instruction sequence in the assembly output and
    was special-cased in the X86CodeEmitter's emitInstruction()
    function. That broke indirect calls in the same way as above.

    This patch also removes a hack forcing Darwin to the small code model.
    Without far-call-stubs, the small code model requires things of the
    JITMemoryManager that the DefaultJITMemoryManager can't provide.

    Thanks to echristo for lots of testing!

    Make sure that if anyone passes a name by accident for the isSigned
    parameter of CreateIntCast then they get an error from the compiler
    (or from the linker with a non-gcc compiler).  Another possibility
    is to flip the order of the DestTy and isSigned parameters, since you
    should then get a compiler warning if you try to use a char* for a
    Type*.

    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).

    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:

    - 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.

       the tail size is smaller than the generic threshold.

       non-fallthrough blocks.

    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.

Date:   Tue Nov 10 22:14:04 2009 +0000

    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.

    Add a monstrous hack to improve X86ISelDAGToDAG compile time.
     - 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.

      br i1 %F, label %X, label %Y

    to a fully threaded:

    add a new SimplifyInstruction API, which is like ConstantFoldInstruction,
    except that the result may not be a constant.  Switch jump threading to
    use it so that it gets things like (X & 0) -> 0, which occur when phi preds
    are deleted and the remaining phi pred was a zero.

    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!

    The jump table was being generated before the end label for exception handling

    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

    `Lset501eh' is now something huge instead of the real value.

    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.

    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.

    legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451.

    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

    - Teach Thumb2InstrInfo::isIdentical() to check two t2LDRpci_pic are identical.
      Since pc relative constantpool entries are always different, this requires it
      it check if the values can actually the same.

    My previous patch (r84124) for setting the encoding bits 4 and 7 of DPSoRegFrm
    was wrong and too aggressive in the sense that DPSoRegFrm includes both constant
    shifts (with Inst{4} = 0) and register controlled shifts (with Inst{4} = 1 and
    Inst{7} = 0).  The 'rr' fragment of the multiclass definitions actually means
    register/register with no shift, see A8-11.

    Re-commit r86077 now that r86290 fixes the 179.art and 175.vpr ARM regressions.

    Here is the original commit message:

    This commit updates malloc optimizations to operate on malloc calls that have constant int size arguments.

    Update CreateMalloc so that its callers specify the size to allocate:
    MallocInst-autoupgrade users use non-TargetData-computed allocation sizes.
    Optimization uses use TargetData to compute the allocation size.

    Now that malloc calls can have constant sizes, update isArrayMallocHelper() to use TargetData to determine the size of the malloced type and the size of malloced arrays.
    Extend getMallocType() to support malloc calls that have non-bitcast uses.

    Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses.  The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly.

    Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses.  The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use.

    Update OptimizeOnceStoredGlobal() to not care about the malloc calls' bitcast use.

    Update all globalopt malloc tests to not rely on autoupgraded-MallocInsts, but instead use explicit malloc calls with correct allocation sizes.

    - Add pseudo instructions tLDRpci_pic and t2LDRpci_pic which does a pc-relative
      load of a GV from constantpool and then add pc. It allows the code sequence to
      be rematerializable so it would be hoisted by machine licm.
    - Add a late pass to break these pseudo instructions into a number of real
      instructions. Also move the code in Thumb2 IT pass that breaks up t2MOVi32imm
      to this pass. This is done before post regalloc scheduling to allow the
      scheduler to proper schedule these instructions. It also allow them to be
      if-converted and shrunk by later passes.

    Extend jump threading to support much more general threading
    predicates.  This allows us to jump thread things like:

    _ZN12StringSwitchI5ColorE4CaseILj7EEERS1_RAT__KcRKS0_.exit119:
      %tmp1.i24166 = phi i8 [ 1, %bb5.i117 ], [ %tmp1.i24165, %_Z....exit ], [ %tmp1.i24165, %bb4.i114 ]
      %toBoolnot.i87 = icmp eq i8 %tmp1.i24166, 0     ; <i1> [#uses=1]
      %tmp4.i90 = icmp eq i32 %tmp2.i, 6              ; <i1> [#uses=1]
      %or.cond173 = and i1 %toBoolnot.i87, %tmp4.i90  ; <i1> [#uses=1]
      br i1 %or.cond173, label %bb4.i96, label %_ZN12...

    Where it is "obvious" that when coming from %bb5.i117 that the 'and' is always
    false.  This triggers a surprisingly high number of times in the testsuite,
    and gets us closer to generating good code for doug's strswitch testcase.

    This also make a bunch of other code in jump threading redundant, I'll rip
    out in the next patch.  This survived an enable-checking llvm-gcc bootstrap.

    Add an assertion to catch indirectbr in SplitBlockPredecessors. This
    makes several optimization passes abort in cases where they're currently
    silently miscompiling code.

    Remove the indirectbr assertion from SplitEdge. Indirectbr is only
    a problem for critical edges, and SplitEdge defers to SplitCriticalEdge
    to handle those, and SplitCriticalEdge has its own assertion for
    indirectbr.

    Update CreateMalloc so that its callers specify the size to allocate:
    MallocInst-autoupgrade users use non-TargetData-computed allocation sizes.
    Optimization uses use TargetData to compute the allocation size.

    Now that malloc calls can have constant sizes, update isArrayMallocHelper() to use TargetData to determine the size of the malloced type and the size of malloced arrays.
    Extend getMallocType() to support malloc calls that have non-bitcast uses.

    Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses.  The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly.

    Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses.  The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use.

    Update OptimizeOnceStoredGlobal() to not care about the malloc calls' bitcast use.

    Update all globalopt malloc tests to not rely on autoupgraded-MallocInsts, but instead use explicit malloc calls with correct allocation sizes.

    Implement some new transforms for optimizing
    subtracts of two pointer to ints into the same vector.  This happens
    for C++ iterator idioms for example, stringmap takes a const char*
    that points to the start and end of a string.  Once inlined, we want

    The 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.

    LLVMCConfigurationEmitter.cpp when built with an llvm-gcc that has ipsccp

    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

    Use the libanalysis 'ConstantFoldLoadFromConstPtr' function
    instead of reinventing SCCP-specific logic.  This gives us
    new powers.

    switch the main 'ValueState' map from being an std::map to being
    a DenseMap.  Doing this required being aware of subtle iterator
    invalidation issues, but it provides a big speedup.  In a
    release-asserts build, this sped up optimizing 403.gcc from
    1.34s -> 0.79s (IPSCCP) and 1.11s -> 0.44s (SCCP).

    This commit also conflates in a bunch of general cleanups, sorry.

    fix two strange things in the default passmgr:

    1. we'd run simplifycfg at the very start, even though
    the per function passes have already cleaned this up.

    2. In the main per-function pipeline that is interlaced with inlining
       etc, we would do instcombine, jump threading, simplifycfg *before*
       doing SROA.  SROA is much more likely to expose opportunities for
       these passes than they are for SROA, so move SRoA up earlier.

    also add some comments.

    We currently only run ipsccp at LTO time, which is silly.  It subsumes
    ipconstprop and doesn't take much time.  Just run it in its place.

    This adds a testcase for it, which I plan to expand to cover other
    "integration" cases, where we expect the optimizer to be able to
    eliminate various things.  Due to phase order issues we've regressed
    in a number of areas and integration tests are the only way I see to
    prevent this.

    change llvm::MergeBlockIntoPredecessor to not merge two blocks BB1->BB2
    when BB2 has its address taken.  Since it ends up doing BB2->rauw(BB1),
    this can cause the address of the entry block to be taken.  Since it is
    generally undesirable to nuke blocks whose address is taken, even when
    we can, just unconditionally stop this xform.

    would be a good adjustment.

    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.

    When cross-building, the CFLAGS and CXXFLAGS are for the target, and don't
    apply to the build tools. If we want to allow build tool flags input, we
    should have separate inputs (BUILD_CFLAGS and BUILD_CXXFLAGS, perhaps).

    This fixes functions like

    void f (int a1, int a2, int a3, int a4, int a5,...)

    In ARMTargetLowering::LowerFormalArguments if the function has 4 or
    more regular arguments we used to set VarArgsFrameIndex using an
    offset of 0, which is only correct if the function has exactly 4
    regular arguments.

    When the function is doing dynamic stack realignment, the spill slot will be

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

    When there is a 2-instruction spill sequence, record
    the second (store) instruction in SpillSlotToUsesMap
    consistently.  I don't think this matters functionally,
    but it's cleaner and Evan wants it this way.

    spill sequences correctly (PPC Altivec).  We need to

    ElementSize * ArraySize
    ArraySize << log2(ElementSize)

    Refactor isArrayMallocHelper and delete isSafeToGetMallocArraySize, so that there is only 1 copy of the malloc array determining logic.

    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.

Author: Chris Lattner <sabre@nondot.org>
Date:   Wed Oct 28 03:39:23 2009 +0000

    full asmparser support for blockaddress.  We can now do:
    $ llvm-as foo.ll -d -disable-output

    which reads and prints the .ll file.  BC encoding is the
    next project.  Testcase will go in once that works.

    Update SystemZ to use PSW following the way x86 uses EFLAGS. Besides
    eliminating a use of MVT::Flag, this is needed for an upcoming CodeGen
    change.

    This unfortunately requires SystemZ to switch to the list-burr
    scheduler, in order to handle the physreg defs properly, however
    that's what LLVM has available at this time.

Author: Bob Wilson <bob.wilson@apple.com>

    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.

    - Revert some changes from 85044, 85045, and 85047 that broke x86_64 tests and
      bootstrapping. It's not safe to leave identity subreg_to_reg and insert_subreg
      around.
    - Relax register scavenging to allow use of partially "not-live" registers. It's
      common for targets to operate on registers where the top bits are undef. e.g.
      s0 =
      d0 = insert_subreg d0<undef>, s0, 1
      ...
         = d0
      When the insert_subreg is eliminated by the coalescer, the scavenger used to
      complain. The previous fix was to keep to insert_subreg around. But that's
      brittle and it's overly conservative when we want to use the scavenger to
      allocate registers. It's actually legal and desirable for other instructions
      to use the "undef" part of d0. e.g.
      s0 =
      d0 = insert_subreg d0<undef>, s0, 1
      ...
      s1 =
         = s1
         = d0
      We probably need add a "partial-undef" marker on machine operand so the
      machine verifier would not complain.

commit 8e39cf73d44aea2c233909dff6504362a6ccce8e
Author: Chris Lattner <sabre@nondot.org>
Date:   Sun Oct 25 06:15:37 2009 +0000

    Teach FoldBitCast to be able to handle bitcasts from (e.g.) i128 -> <4 x float>.

    This allows us to simplify this:
    union vec2d {
        double e[2];
        double v __attribute__((vector_size(16)));
    };
    typedef union vec2d vec2d;

    static vec2d a={{1,2}}, b={{3,4}};

    vec2d foo () {
        return (vec2d){ .v = a.v + b.v * (vec2d){{5,5}}.v };
    }

    down to:

    define %0 @foo() nounwind ssp {
    entry:
      %mrv5 = insertvalue %0 undef, double 1.600000e+01, 0 ; <%0> [#uses=1]
      %mrv6 = insertvalue %0 %mrv5, double 2.200000e+01, 1 ; <%0> [#uses=1]
      ret %0 %mrv6
    }

    instead of:

    define %0 @foo() nounwind ssp {
    entry:
      %mrv5 = insertvalue %0 undef, double extractelement (<2 x double> fadd (<2 x double> fmul (<2 x double> bitcast (<1 x i128> <i128 85174437667405312423031577302488055808> to <2 x double>), <2 x double> <double 3.000000e+00, double 4.000000e+00>), <2 x double> <double 1.000000e+00, double 2.000000e+00>), i32 0), 0 ; <%0> [#uses=1]
      %mrv6 = insertvalue %0 %mrv5, double extractelement (<2 x double> fadd (<2 x double> fmul (<2 x double> bitcast (<1 x i128> <i128 85174437667405312423031577302488055808> to <2 x double>), <2 x double> <double 3.000000e+00, double 4.000000e+00>), <2 x double> <double 1.000000e+00, double 2.000000e+00>), i32 1), 1 ; <%0> [#uses=1]
      ret %0 %mrv6

    Restrict Thumb1 register allocation to low registers, even for instructions that
    can access the hi regs. Our prologue and epilogue code doesn't know how to
    properly handle save/restore of the hi regs, so things go badly when we alloc
    them.

    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.

Date:   Thu Oct 22 06:25:11 2009 +0000

    Move some constant folding logic for loads out of instcombine into
    Analysis/ConstantFolding.cpp.  This doesn't change the behavior of
    instcombine but makes other clients of ConstantFoldInstruction
    able to handle loads.  This was partially extracted from Eli's patch
    in PR3152.

    Revert the main portion of r31856. It was causing BranchFolding
    to break up CFG diamonds by banishing one of the blocks to the end of
    the function, which is bad for code density and branch size.

    This does pessimize MultiSource/Benchmarks/Ptrdist/yacr2, the
    benchmark cited as the reason for the change, however I've examined
    the code and it looks more like a case of gaming a particular
    branch than of being generally applicable.

    Most changes are cleanup, but there is 1 correctness fix:
    I fixed InstCombine so that the icmp is removed only if the malloc call is removed (which requires explicit removal because the Worklist won't DCE any calls since they can have side-effects).

    Incorporate various suggestions Chris gave during metadata review.

    - i < getNumElements()  instead of getNumElements() > i
    - Make setParent() private
    - Fix use of resizeOperands
    - Reset HasMetadata bit after removing all metadata attached to an instruction
    - Efficient use of iterators

    in the PHI's Basic Block. This uses a conservative approach, because we don't

    Add a pass to overlay pic16 data sections for function frame and automatic
    variables. This pass can be invoked by llvm-ld or opt to traverse over the call graph
    to detect what function frames and their automatic variables can be overlaid.
    Currently this builds an archive , but needs to be changed to a loadable module.

    make GVN work better when TD is not around:

    "In the existing code, if the load and the value to replace it with are
    of different types *and* target data is available, it tries to use the
    target data to coerce the replacement value to the type of the load.
    Otherwise, it skips all effort to handle the type mismatch and just
    feeds the wrongly-typed replacement value to replaceAllUsesWith, which
    triggers an assertion.

    The patch replaces it with an outer if checking for type mismatch, and
    an inner if-else that checks whether target data is available and, if
    not, returns false rather than trying to replace the load."

    Restore LoopUnswitch's block-oriented threshold. LoopUnswitch now checks both
    the estimated code size and the number of blocks when deciding whether to
    do a non-trivial unswitch. This protects it from some very undesirable
    worst-case behavior on large numbers of loop-unswitchable conditions, such
    as in the testcase in PR5259.

    Move the Function*->allocated blocks map from the JITMemoryManager to the
    JITEmitter.

    I'm gradually making Functions auto-remove themselves from the JIT when they're
    destroyed. In this case, the Function needs to be removed from the JITEmitter,
    but the map recording which Functions need to be removed lived behind the
    JITMemoryManager interface, which made things difficult.

    This patch replaces the deallocateMemForFunction(Function*) method with a pair
    of methods deallocateFunctionBody(void *) and deallocateExceptionTable(void *)
    corresponding to the two startFoo/endFoo pairs.

    Make TranslateX86CC return COND_INVALID instead of aborting when it
    encounters an OEQ or UNE comparison, and update its callers to check
    for this return status and recover. This fixes a problem resulting from
    the LowerOperation hooks being called from LegalizeVectorOps, because
    LegalizeVectorOps only lowers vectors, so OEQ and UNE comparisons may
    still be at large. This fixes PR5092.

    Fix PR4313: IPSCCP was not setting the lattice value for the invoke instruction
    when the invoke had multiple return values: it set the lattice value only on the
    extractvalue.
    This caused the invoke's lattice value to remain the default (undefined), and
    later propagated to extractvalue's operand, which incorrectly introduces
    undefined behavior.

    remove strings from instructions who are never asmprinted.
    All of these "subreg32" modifier instructions are handled
    explicitly by the MCInst lowering phase.  If they got to
    the asmprinter, they would explode.  They should eventually
    be replace with correct use of subregs.

    Clean up the JITResolver stub/callsite<->function maps.

    The JITResolver maps Functions to their canonical stubs and all callsites for
    lazily-compiled functions to their target Functions. To make Function
    destruction work, I'm going to need to remove all callsites on destruction, so
    this patch also adds the reverse mapping for that.

    There was an incorrect assumption in here that the only stub for a function
    would be the one caused by needing to lazily compile it, while x86-64 far calls
    and dlsym-stubs could also cause such stubs, but I didn't look for a test case
    that the assumption broke.

    This also adds DenseMapInfo<AssertingVH> so I can use DenseMaps instead of
    std::maps.

    -Revert parts of 84326 and 84411. Distinquishing between fixed and non-fixed
    stack slots and giving them different PseudoSourceValue's did not fix the
    problem of post-alloc scheduling miscompiling llvm itself.
    - Apply Dan's conservative workaround by assuming any non fixed stack slots can
    alias other memory locations. This means a load from spill slot #1 cannot
    move above a store of spill slot #2.
    - Enable post-alloc scheduling for x86 at optimization leverl Default and above.

    Support GoogleTest's "typed tests"
    (http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide#Typed_Tests)
    in lit.py.  These tests have names like "ValueMapTest/0.Iteration", which broke
    when lit.py os.path.join()ed them onto the path and then assumed it could
    os.path.split() them back off.  This patch shifts path components from the
    testPath to the testName until the testPath exists.

    Enhance CodePlacementOpt's unconditional intra-loop branch elimination logic
    to be more general and understand more varieties of loops.

    Teach CodePlacementOpt to reorganize the basic blocks of a loop so that
    they are contiguous. This also includes a fair amount of logic for preserving
    fall-through edges while doing so. This fixes a BranchFolding-ism where blocks
    which can't be made to use a fall-through edge and don't conveniently fit
    anywhere nearby get tossed out to the end of the function.

    Revert svn r80498 and replace it with a different solution.  The only problem
    I can see with the original code was that I forgot that this runs after
    type legalization and hence the result type will always be i32. (Custom
    legalization of EXTRACT_VECTOR_ELT is only enabled for vector types with
    8- and 16-bit elements.)

    Regarding the FIXME comment: any information about sign and zero-extension
    should be captured by separate extension operations.  The DAG combiner should
    handle those to produce either VGETLANEu or VGETLANEs, and that seems to be
    working now.  If there are cases that we're missing, let me know.

    Fix a potential performance problem in placing ARM constant pools.
    In the case where there are no good places to put constants and we fall back
    upon inserting unconditional branches to make new blocks, allow all constant
    pool references in range of those blocks to put constants there, even if that
    means resetting the "high water marks" for those references.  This will still
    terminate because you can't keep splitting blocks forever, and in the bad
    cases where we have to split blocks, it is important to avoid splitting more
    than necessary.

    More bits of the ARM target assembler for llvm-mc, code added to parse labels
    as expressions, code for parsing a few arm specific directives (still needs
    the MCStreamer calls for these).  Some clean up of the operand parsing code
    and adding some comments.

    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.

    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.

    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.

    Delete a comment that makes no sense to me.  The statement that moving a CPE
    before its reference is only supported on ARM has not been true for a while.
    In fact, until recently, that was only supported for Thumb.  Besides that,
    CPEs are always a multiple of 4 bytes in size, so inserting a CPE should have
    no effect on Thumb alignment.

commit e5001730bd4aa9b23daa7861ea3ef08c35e77777
Author: Bob Wilson <bob.wilson@apple.com>

    Last week, ARMConstantIslandPass was failing to converge for the
    MultiSource/Benchmarks/MiBench/automotive-susan test.  The failure has
    since been masked by an unrelated change (just randomly), so I don't have
    a testcase for this now.  Radar 7291928.

    The situation where this happened is that a constant pool entry (CPE) was
    placed at a lower address than the load that referenced it.  There were in
    fact 2 CPEs placed at adjacent addresses and referenced by 2 loads that were
    close together in the code.  The distance from the loads to the CPEs was
    right at the limit of what they could handle, so that only one of the CPEs
    could be placed within range.  On every iteration, the first CPE was found
    to be out of range, causing a new CPE to be inserted.  The second CPE had
    been in range but the newly inserted entry pushed it too far away.  Thus the
    second CPE was also replaced by a new entry, which in turn pushed the first
    CPE out of range.  Etc.

    Judging from some comments in the code, the initial implementation of this
    pass did not support CPEs placed _before_ their references.  In the case
    where the CPE is placed at a higher address, the key to making the algorithm
    terminate is that new CPEs are only inserted at the end of a group of adjacent
    CPEs.  This is implemented by removing a basic block from the "WaterList"
    once it has been used, and then adding the newly inserted CPE block to the
    list so that the next insertion will come after it.  This avoids the ping-pong
    effect where CPEs are repeatedly moved to the beginning of a group of
    adjacent CPEs.  This does not work when going backwards, however, because the
    entries at the end of an adjacent group of CPEs are closer than the CPEs
    earlier in the group.

    To make this pass terminate, we need to maintain a property that changes can
    only happen in some sort of monotonic fashion.  The fix used here is to require
    that the CPE for a particular constant pool load can only move to lower
    addresses.  This is a very simple change to the code and should not cause
    any significant degradation in the results.

    allow this testcase to pass with recent changes.  The test hasn't been
    producing any stores at all for a long time, but ".store." was in some
    IR instruction names until recently.  This removal caused the test to
    start failing.  Just make it reject any stores.

commit 89f19d1b3a3da269ee5267eab8dad7c07def855b
Author: Chris Lattner <sabre@nondot.org>
Date:   Sun Oct 11 23:02:46 2009 +0000

    remove some harmful code that would turn an insertelement on an undef
    into a shuffle even if it was used by another insertelement.  If the
    visitation order of instcombine was wrong, this would turn a chain of
    insertelements into a chain of shufflevectors, which was quite painful.

    Since CollectShuffleElements handles these cases, the code can just
    be nuked.

    generalize a transformation even more: we don't care whether the
    input the the mul is a zext from bool, just that it is all zeros
    other than the low bit.  This fixes some phase ordering issues
    that would cause us to miss some xforms in mul.ll when the worklist
    is visited differently.

    populate instcombine's initial worklist more carefully, causing
    it to visit instructions from the start of the function to the

    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.

Author: Chris Lattner <sabre@nondot.org>
Date:   Sat Oct 10 23:50:30 2009 +0000

    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).

    Mark the LDR instruction with isReMaterializable, as it is rematerializable

Author: Dan Gohman <gohman@apple.com>
Date:   Fri Oct 9 23:27:56 2009 +0000

    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.

    Fix the x86 test-shrink optimization so that it doesn't shrink comparisons
    when one of the bits being tested would end up being the sign bit in the
    narrower type, and a signed comparison is being performed, since this would
    change the result of the signed comparison. This fixes PR5132.

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.

    MingW build fixes
