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

    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.

    switch to TrackingVH instead of WeakVH, since these can never
    be RAUW'd and go to null.  This also gets us some sorely lacking

    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.

Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Dec 28 23:41:32 2009 +0000

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

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

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

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

    Define the new operator<< for sets into namespace std, so that

    Substantially optimize APFloat::toString() by doing a single large divide to
    cut the significand down to the desired precision *before* entering the
    core divmod loop.  Makes the overall algorithm logarithmic in the exponent.

    There's still a lot of room for improvement here, but this gets the
    performance back down to acceptable-for-diagnostics levels, even for
    long doubles.

    Add accessors for the largest-magnitude, smallest-magnitude, and
    smallest-normalized-magnitude values in a given FP semantics.
    Provide an APFloat-to-string conversion which I am quite ready to admit could
    be much more efficient.

Date:   Thu Dec 24 01:07:17 2009 +0000

    handle equality memcmp of 8 bytes on x86-64 with two unaligned loads and a
    compare.  On other targets we end up with a call to memcmp because we don't
    want 16 individual byte loads.  We should be able to use movups as well, but
    we're failing to select the generated icmp.

    move an optimization for memcmp out of simplifylibcalls and into
    SDISel.  This optimization was causing simplifylibcalls to
    introduce type-unsafe nastiness.  This is the first step, I'll be
    expanding the memcmp optimizations shortly, covering things that
    we really really wouldn't want simplifylibcalls to do.

    Move the extern symbol declarations outside of
    DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
    linkage.

    Interestingly, GCC treats the block-scoped "extern" declarations we
    previously had as if they were extern "C" declarations (or, at least,
    were in the global namespace), so that GCC bug papered over this LLVM
    bug. Clang and EDG get the linkage correct; this new variant seems to
    work for both GCC and Clang.

    Provide dbgs(), a circular-buffering debug output stream.  By default it
    simply passes output to errs().  If -debug-buffer-size=N is set N > 0,
    dbgs() buffers its output until program termination and dumps the last N
    characters sent to it.  This is handy when debugging very large inputs.

    Add circular_raw_ostream, which buffers its output in a circular queue
    and outputs it when explicitly flushed.  The intent is to use it in
    situations such as debug output logging where a signal handler can take
    care of flushing the buffer at program termination.

    stop pattern matching 16-bit zero's of a register to MOV16r0,
    instead use the appropriate subreggy thing.  This generates identical
    code on some large apps (thanks to Evan's cross class coalescing
    stuff he did back in july).  This means that MOV16r0 can go away
    completely in the future soon.

    Add a SPR register class to the ARM target.

    Certain Thumb instructions require only SP (e.g. tSTRspi).

    Partially revert r91626.  Materializing extra functions to determine whether
    they're available_externally broke VMKit, which was relying on the fact that
    functions would only be materialized when they were first called.  We'll have
    to wait for http://llvm.org/PR5737 to really fix this.

    I also added a test for one of the F->isDeclaration() calls which wasn't
    covered by anything else in the test suite.

    Fix the Convert to scalar to not insert dead loads in the store case.  The
    load is needed when we have a small store into a large alloca (at which
    point we get a load/insert/store sequence), but when you do a full-sized
    store, this load ends up being dead.

    This dead load is bad in really large nasty testcases where the load ends
    up causing mem2reg to insert large chains of dependent phi nodes which only
    ADCE can delete.  Instead of doing this, just don't insert the dead load.

    This fixes rdar://6864035

    Add a fastpath to Load GVN to special case when we have exactly one dominating
    load to avoid even messing around with SSAUpdate at all.  In this case (which
    is very common, we can just use the input value directly).

    This speeds up GVN time on gcc.c-torture/20001226-1.c from 36.4s to 16.3s,
    which still isn't great, but substantially better and this is a simple speedup
    that applies to lots of different cases.

    Remove uber-gross hack. The define _snprintf to snprintf is invalid due to two reasons: 1. Accroding to C++ standard snprintf should be available in std namespace (and __gnu_cxx in case of GCC to). Such ifdef will change all snprintf's to _snprintf's, but won't bring snprintf to all necessary namespaces. Thus e.g. any locale-using code on mingw will yield an error (include this file + string to see the result) 2. MSVCRT's _snprintf does not comply with C99 standard. Standard one is snprintf.

    Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit
    incarnations), integrated into the MC framework.

    The disassembler is table-driven, using a custom TableGen backend to
    generate hierarchical tables optimized for fast decode.  The disassembler
    consumes MemoryObjects and produces arrays of MCInsts, adhering to the
    abstract base class MCDisassembler (llvm/MC/MCDisassembler.h).

    The disassembler is documented in detail in

    - lib/Target/X86/Disassembler/X86Disassembler.cpp (disassembler runtime)
    - utils/TableGen/DisassemblerEmitter.cpp (table emitter)

    You can test the disassembler by running llvm-mc -disassemble for i386
    or x86_64 targets.  Please let me know if you encounter any problems
    with it.

    Make some methods const.  The only interesting change here is that

    Changes from review:

    - Move DisableScheduling flag into TargetOption.h
    - Move SDNodeOrdering into its own header file. Give it a minimal interface that
      doesn't conflate construction with storage.
    - Move assigning the ordering into the SelectionDAGBuilder.

    This isn't used yet, so there should be no functional changes.

    Formalize MDNode's function-localness:
    - an MDNode is designated as function-local when created, and continues to be even if its operands are modified not to refer to function-local IR
    - function-localness is designated via lowest bit in SubclassData
    - getLocalFunction() descends MDNode tree to see if it is consistently function-local

    Add verification of MDNodes to checks that MDNodes are consistently function-local.
    Update AsmWriter to use isFunctionLocal().

    Fix libstdc++ build on ARM linux and part of PR5770.

    MI was not being used but it was also not being deleted, so it was kept in the garbage list. The memory itself was freed once the function code gen was done.

    Once in a while the codegen of another function would create an instruction on the same address. Adding it to the garbage group would work once, but when another pointer was added it would cause an assert as "Cache" was about to be pushed to Ts.

    For a patch that make us detect problems like this earlier, take a look at

    http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20091214/092758.html

    With that patch we assert as soon and the new instruction is added to the garbage set.

    On recent Intel u-arch's, folding loads into some unary SSE instructions can
    be non-optimal. To be precise, we should avoid folding loads if the instructions
    only update part of the destination register, and the non-updated part is not
    needed. e.g. cvtss2sd, sqrtss. Unfolding the load from these instructions breaks
    the partial register dependency and it can improve performance. e.g.

    movss (%rdi), %xmm0
    cvtss2sd %xmm0, %xmm0

    instead of
    cvtss2sd (%rdi), %xmm0

    An alternative method to break dependency is to clear the register first. e.g.
    xorps %xmm0, %xmm0
    cvtss2sd (%rdi), %xmm0

    Pass the error string directly to llvm_unreachable instead of the residual
    (0 && "error").  Rough consensus seems to be that g++ *should* be diagnosing
    this because the pointer makes it not an ICE in c++03.  Everyone agrees that
    the current standard is silly and null-pointer-ness should not be based on
    ICE-ness.  Excellent fight scene in Act II, denouement weak, two stars.

    Instruction fixes, added instructions, and AsmString changes in the
    X86 instruction tables.

    Also (while I was at it) cleaned up the X86 tables, removing tabs and
    80-line violations.

    This patch was reviewed by Chris Lattner, but please let me know if
    there are any problems.

    * X86*.td

    		differently
    	(MOV) Changed immediates to offsets, which is more correct;

    Turn off critical edge splitting for landing pads. The introduction of a
    non-landing pad basic block as the successor to a block that ends in an
    unconditional jump will cause block folding to remove the added block as a
    successor. Thus eventually removing it AND the landing pad entirely. Critical
    edge splitting is an optimization, so we can safely turn it off when dealing
    with landing pads.

    Slightly generalize transformation of memmove(a,a,n) so that it also applies
    to memcpy. (Such a memcpy is technically illegal, but in practice is safe
    and is generated by struct self-assignment in C code.)

    Introduce EVT::getHalfSizedIntegerVT() for use in ExpandUnalignedStore() in
    LegalizeDAG.cpp. Unlike the code it replaces, which simply decrements the simple
    type by one, getHalfSizedIntegerVT() searches for the smallest simple integer
    type that is at least half the size of the type it is called on. This approach
    has the advantage that it will continue working if a new value type (such as
    i24) is added to MVT.

    Also, in preparation for new value types, remove the assertions that
    non-power-of-2 8-bit-mutiple types are Extended when legalizing extload and
    truncstore operations.

    Reuse lowered phi nodes.

    Tail duplication produces lots of identical phi nodes in different basic
    blocks. Teach PHIElimination to reuse the join registers when lowering a phi
    node that is identical to an already lowered node. This saves virtual
    registers, and more importantly it avoids creating copies the the coalescer
    doesn't know how to eliminate.

    Teach LiveIntervalAnalysis about the phi joins with multiple uses.

    This patch significantly reduces code size produced by -pre-regalloc-taildup.

Author: Dale Johannesen <dalej@apple.com>

    Do better with physical reg operands (typically, from inline asm)
    in local register allocator.  If a reg-reg copy has a phys reg
    input and a virt reg output, and this is the last use of the phys
    reg, assign the phys reg to the virt reg.  If a reg-reg copy has
    a phys reg output and we need to reload its spilled input, reload
    it directly into the phys reg than passing it through another reg.

    Following 76208, there is sometimes no dependency between the def of
    a phys reg and its use; this creates a window where that phys reg
    can be used for spilling (this is true in linear scan also).  This
    is bad and needs to be fixed a better way, although 76208 works too
    well in practice to be reverted.  However, there should normally be
    no spilling within inline asm blocks.  The patch here goes a long way
    towards making this actually be true.

    Change indirect-globals to use a dedicated allocIndirectGV.  This lets us
    remove start/finishGVStub and the BufferState helper class from the

    Reapply 91184 with fixes and an addition to the testcase to cover the problem
    found last time.  Instead of trying to modify the IR while iterating over it,
    I've change it to keep a list of WeakVH references to dead instructions, and
    then delete those instructions later.  I also added some special case code to
    detect and handle the situation when both operands of a memcpy intrinsic are
    referencing the same alloca.

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

    Also, when rewriting GEP instructions, mark them as "in-bounds" since all the
    indices are known to be safe.

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

    This is the meat of that fix:

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

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

    Simplify this class by removing the result cache.

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

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

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

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

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

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

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

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

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

    Add a minor optimization: if we haven't changed the operands of an

    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).

Author: Lang Hames <lhames@gmail.com>
Date:   Wed Dec 9 05:39:12 2009 +0000

    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
    stores is not phi translating, thus it miscompiles really
    crazy testcases.  This is from inspection, I haven't seen
    this in the wild.

commit efff322bd17b640f544a1d28c580b59499a28ff8
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.

    For VC++, define the ?INT*_C macros only it they are not yet defined.

    Some compatibility updates like the Boost TR1 compatibility headers
    define them.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    becomes:

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

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

    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.

    Only print edgeSourceLabels if they are not empty

    Graphviz can layout the graphs better if a node does not contain source
    ports. Therefore only print the ports if the source ports are useful,
    that means are not labeled with the empty string "".
    This patch also simplifies graphs without any edgeSourceLabels e.g. the
    dominance trees.

    Commit r90099 made LLVM simplify one of these constant expressions a little
    more. Update the syntax we're checking for and filecheckize it too.

    This will fix the selfhost buildbots but will 'break' the others (sigh) because
    they're still linked against older LLVM which is emitting less optimized IR.

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

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

    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.

    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.

    the problem only shows for msp430 and pic16 which is why it specifies

    Add instruction flags: hasExtraSrcRegAllocReq and hasExtraDefRegAllocReq. When
    set, these flags indicate the instructions source / def operands have special
    register allocation requirement that are not captured in their register classes.
    Post-allocation passes (e.g. post-alloc scheduler) should not change their
    allocations. e.g. ARM::LDRD require the two definitions to be allocated
    even / odd register pair.

    Add a new virtual EmitStartOfAsmFile method to the AsmPrinter and use this
    to emit target-specific things at the beginning of the asm output.  This
    fixes a problem for PPC, where the text sections are not being kept together
    as expected.  The base class doInitialization code calls DW->BeginModule()
    which emits a bunch of DWARF section directives.  The PPC doInitialization
    code then emits all the TEXT section directives, with the intention that they
    will be kept together. But as I understand it, the Darwin assembler treats
    the default TEXT section as a special case and moves it to the beginning of
    the file, which means that all those DWARF sections are in the middle of
    the text.  With this change, the EmitStartOfAsmFile hook is called before
    the DWARF section directives are emitted, so that all the PPC text section
    directives come out right at the beginning of the file.

    Fix integer overflow in instruction scheduling.  This can happen if we have
    basic blocks that are so long that their size overflows a short.

    Also assert that overflow does not happen in the future, as requested by Evan.

    This fixes PR4401.

    Add a way for a frontend to generate more complex dwarf location
    information.  This allows arbitrary code involving DW_OP_plus_uconst
    and DW_OP_deref.  The scheme allows for easy extention to include,
    any, or all of the DW_OP_ opcodes.  I thought about just exposing all
    of them, but, wasn't sure if people wanted the dwarf opcodes exposed
    in the api.  Is that a layering violation?

    With this scheme, the entire existing block scheme used by llvm-gcc
    can be switched over to the new scheme.  I think that would be
    cleaner, as then the compiler specific bits are not present in llvm
    proper.  Before the old code can be yanked however, similar code in
    clang would have to be removed.

    Next up, more testing.

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

    Coalescer should not delete extract_subreg, insert_subreg, and subreg_to_reg of
    physical registers. This is especially critical for the later two since they
    start the live interval of a super-register. e.g.
    %DO<def> = INSERT_SUBREG %D0<undef>, %S0<kill>, 1
    If this instruction is eliminated, the register scavenger will not be happy as
    D0 is not defined previously.
    This fixes PR5055.

    Move the dominator verification code out of special code embedded within

    Also, reorganize loop verification. Make the LoopPass infrastructure
    call verifyLoop as needed instead of having LoopInfo::verifyAnalysis
    check every loop in the function after each looop pass. Add a new
    command-line argument, -verify-loop-info, to enable the expensive
    full checking.

    Instead of testing whether an instruction dominates the loop preheader,
    test whether it properly dominates the loop header. This is equivalent
    when the loop has a preheader, and has the advantage of working when
    the loop doesn't have a preheader. Since IVUsers doesn't Require
    LoopSimplify, the loop isn't guaranteed to have a preheader.

    Move the integer type out of 'derived' and into 'primitive'. This permits us
    to explain that derived types are all composed of other types, which primitive
    types aren't. Without moving integer out of derived, this wouldn't be true.

    Perform a few trivial cleanups; 'i1' went from a link to #t_primitive to
    #t_integer (a holdover from when it was a bool type I suppose).

    Improve MachineMemOperand handling.
     - Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions.
       This eliminates MachineInstr's std::list member and allows the data to be
       created by isel and live for the remainder of codegen, avoiding a lot of
       copying and unnecessary translation. This also shrinks MemSDNode.
     - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated
       fields for MachineMemOperands.
     - Change MemSDNode to have a MachineMemOperand member instead of its own
       fields with the same information. This introduces some redundancy, but
       it's more consistent with what MachineInstr will eventually want.
     - Ignore alignment when searching for redundant loads for CSE, but remember
       the greatest alignment.

    Target-specific code which previously used MemOperandSDNodes with generic
    SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range
    so that the SelectionDAG framework knows that MachineMemOperand information
    is available.

    reimplement the regex matching strategy by building a single
    regex and matching it instead of trying to match chunks at a time.
    Matching chunks at a time broke with check lines like
      CHECK: foo {{.*}}bar
    because the .* would eat the entire rest of the line and bar would
    never match.

    Now we just escape the fixed strings for the user, so that something
    like:
      CHECK: a() {{.*}}???
    is matched as:
      CHECK: {{a\(\) .*\?\?\?}}
    transparently "under the covers".

    Generate FSQRT from calls to the sqrt function, which
    allows appropriate backends to generate a sqrt instruction.

    On x86, this isn't done at -O0 because we go through
    FastISel instead.  This is a behavior change from before
    this series of sqrt patches started.  I think this is OK
    considering that compile speed is most important at -O0, but
    could be convinced otherwise.

    pr4926: ARM requires the stack pointer to be aligned, even for leaf functions.
    For the AAPCS ABI, SP must always be 4-byte aligned, and at any "public
    interface" it must be 8-byte aligned.  For the older ARM APCS ABI, the stack
    alignment is just always 4 bytes.  For X86, we currently align SP at
    entry to a function (e.g., to 16 bytes for Darwin), but no stack alignment
    is needed at other times, such as for a leaf function.

    After discussing this with Dan, I decided to go with the approach of adding
    a new "TransientStackAlignment" field to TargetFrameInfo.  This value
    specifies the stack alignment that must be maintained even in between calls.
    It defaults to 1 except for ARM, where it is 4.  (Some other targets may
    also want to set this if they have similar stack requirements. It's not
    currently required for PPC because it sets targetHandlesStackFrameRounding
    and handles the alignment in target-specific code.) The existing StackAlignment
    value specifies the alignment upon entry to a function, which is how we've

    Start of revamping the register scavenging in PEI. ARM Thumb1 is the driving
    interest for this, as it currently reserves a register rather than using
    the scavenger for matierializing constants as needed.

    Instead of scavenging registers on the fly while eliminating frame indices,
    new virtual registers are created, and then a scavenged collectively in a
    post-pass over the function. This isolates the bits that need to interact
    with the scavenger, and sets the stage for more intelligent use, and reuse,
    of scavenged registers.

    For the time being, this is disabled by default. Once the bugs are worked out,
    the current scavenging calls in replaceFrameIndices() will be removed and
    the post-pass scavenging will be the default. Until then,
    -enable-frame-index-scavenging enables the new code. Currently, only the
    Thumb1 back end is set up to use it.

    Fix a hypothetical problem for targets with StackGrowsUp and a non-zero
    LocalAreaOffset.  (We don't have any of those right now.)
    PEI::calculateFrameObjectOffsets includes the absolute value of the
    LocalAreaOffset in the cumulative offset value used to calculate the
    stack frame size.  It then adds the raw value of the LocalAreaOffset
    to the stack size.  For a StackGrowsDown target, that raw value is negative
    and has the effect of cancelling out the absolute value that was added
    earlier, but that obviously won't work for a StackGrowsUp target.  Change
    to subtract the absolute value of the LocalAreaOffset.

    Fix PR5024 with a big hammer: disable the double-def assertion in the scavenger.

    LiveVariables add implicit kills to correctly track partial register kills. This works well enough and is fairly accurate. But coalescer can make it impossible to maintain these markers. e.g.

            BL <ga:sss1>, %R0<kill,undef>, %S0<kill>, %R0<imp-def>, %R1<imp-def,dead>, %R2<imp-def,dead>, %R3<imp-def,dead>, %R12<imp-def,dead>, %LR<imp-def,dead>, %D0<imp-def>, ...
    ...
    	%reg1031<def> = FLDS <cp#1>, 0, 14, %reg0, Mem:LD4[ConstantPool]
    ...
       	%S0<def> = FCPYS %reg1031<kill>, 14, %reg0, %D0<imp-use,kill>

    When reg1031 and S0 are coalesced, the copy (FCPYS) will be eliminated the the implicit-kill of D0 is lost. In this case it's possible to move the marker to the FLDS. But in many cases, this is not possible. Suppose

    	%reg1031<def> = FOO <cp#1>, %D0<imp-def>
    ...
       	%S0<def> = FCPYS %reg1031<kill>, 14, %reg0, %D0<imp-use,kill>

    When FCPYS goes away, the definition of S0 is the "FOO" instruction. However, transferring the D0 implicit-kill to FOO doesn't work since it is the def of D0 itself. We need to fix this in another time by introducing a "kill" pseudo instruction to track liveness.

    Disabling the assertion is not ideal, but machine verifier is doing that job now. It's important to know double-def is not a miscomputation since it means a register should be free but it's not tracked as free. It's a performance issue instead.

    Rename several variables from EVT to more descriptive names, now that EVT
    is also the name of their type, as declarations like "EVT EVT" look
    really odd.

    Fix verification of explicit operands.

    The machine code verifier did not check for explicit operands correctly. It
    used MachineInstr::getNumExplicitOperands, but that method may cheat and use
    the declared count in the TargetInstrDesc.

    Now we check the explicit operands one at a time in visitMachineOperand.

    Remove BlackfinRegisterInfo::getFrameIndexOffset since it is the same as the
    default implementation.  Update comment on the default version, which made it

    this method.

    Fix bug in kill flag updating for post-register-allocation scheduling. When the kill flag of a superreg needs to be cleared because there are one or more subregs live, we instead add implicit-defs of those subregs and leave the kill flag on the superreg. This allows us to end the live-range of the superreg without ending the live-ranges of the subregs.

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

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

    Add a TrackingVH value handle.

    This is designed for tracking a value even when it might move (like WeakVH), but it is an error to delete the referenced value (unlike WeakVH0. TrackingVH is templated like AssertingVH on the tracked Value subclass, it is an error to RAUW a tracked value to an incompatible type.

    For implementation reasons the latter error is only diagnosed on accesses to a mis-RAUWed TrackingVH, because we don't want a virtual interface in a templated class.

    The former error is also only diagnosed on access, so that clients are allowed to delete a tracked value, as long as they don't use it. This makes it easier for the client to reason about destruction.

    Minor bug fix. LowerSubregs should translate
    %S0<def> = EXTRACT_SUBREG %Q0<kill>, 1
    to
    %S0<def> = IMPLICIT_DEF %Q0<imp-use,kill>

    Implicit_def does not *read* any register so the operand should be marked "implicit". The missing "implicit" marker on the operand is wrong, but it doesn't actually break anything.

    Fix PR5023: The instruction form of DominatorTree::dominates did not
    take into consideration that the result of an invoke is only valid in
    the normal dest, not the unwind dest.  This caused 'PHINode::hasConstantValue'
    to return true in an invalid situation, causing mem2reg to delete a phi that
    was actually needed.  This caused a crash building 483.xalancbmk.

    Improve GVN to be able to forward substitute a small load
    from a piece of a large store when both are in the same block.

    This allows clang to compile the testcase in PR4216 to this code:

    _test_bitfield:
    	movl	4(%esp), %eax
    	movl	%eax, %ecx
    	andl	$-65536, %ecx
    	orl	$32962, %eax
    	andl	$40186, %eax
    	orl	%ecx, %eax
    	ret

    This is not ideal, but is a whole lot better than the code produced
    by llvm-gcc:

    _test_bitfield:
    	movw	$-32574, %ax
    	orw	4(%esp), %ax
    	andw	$-25350, %ax
    	movw	%ax, 4(%esp)
    	movw	7(%esp), %cx
    	shlw	$8, %cx
    	movzbl	6(%esp), %edx
    	orw	%cx, %dx
    	movzwl	%dx, %ecx
    	shll	$16, %ecx
    	movzwl	%ax, %eax
    	orl	%ecx, %eax
    	ret

    and dramatically better than that produced by gcc 4.2:

    _test_bitfield:
    	pushl	%ebx
    	call	L3
    "L00000000001$pb":
    L3:
    	popl	%ebx
    	movl	8(%esp), %eax
    	leal	0(,%eax,4), %edx

    Don't allow formatted_ostream to be unbuffered, even if its underlying buffer
    is.
     - The problem is that formatted_ostream forces its underlying buffer to be
       unbuffered, so if some client happens to wrap a formatted_ostream around
       something, but still use the underlying stream, then we can end up writing on
       a fully unbuffered output (which was never intended to be unbuffered).

     - This makes clang (and presumably llvm-gcc) -emit-llvm -S a mere 10x faster.

commit 738b4f2a7d37600af45fc6a5515d5a5be175d19e

    Implement the JIT side of the GDB JIT debugging interface.  To enable this
    feature, either build the JIT in debug mode to enable it by default or pass
    -jit-emit-debug to lli.

    Right now, the only debug information that this communicates to GDB is call
    frame information, since it's already being generated to support exceptions in
    the JIT.  Eventually, when DWARF generation isn't tied so tightly to AsmPrinter,
    it will be easy to push that information to GDB through this interface.

    Here's a step-by-step breakdown of how the feature works:

    - The JIT generates the machine code and DWARF call frame info
      (.eh_frame/.debug_frame) for a function into memory.
    - The JIT copies that info into an in-memory ELF file with a symbol for the
      function.
    - The JIT creates a code entry pointing to the ELF buffer and adds it to a
      linked list hanging off of a global descriptor at a special symbol that GDB
      knows about.
    - The JIT calls a function marked noinline that GDB knows about and has put an
      internal breakpoint in.
    - GDB catches the breakpoint and reads the global descriptor to look for new
      code.
    - When sees there is new code, it reads the ELF from the inferior's memory and
      adds it to itself as an object file.
    - The JIT continues, and the next time we stop the program, we are able to
      produce a proper backtrace.

    Consider running the following program through the JIT:

    #include <stdio.h>
    void baz(short z) {
      long w = z + 1;
      printf("%d, %x\n", w, *((int*)NULL));  // SEGFAULT here
    }
    void bar(short y) {
      int z = y + 1;
      baz(z);
    }
    void foo(char x) {
      short y = x + 1;
      bar(y);
    }
    int main(int argc, char** argv) {
      char x = 1;
      foo(x);
    }

    Here is a backtrace before this patch:
    Program received signal SIGSEGV, Segmentation fault.

    Several changes together in a murky mess:
    1. Change some "\n" -> '\n'.
    2. eliminte some std::string's by using raw_ostream::indent.
    3. move a bunch of code out of the main arg parser routine into
       a new static HandlePrefixedOrGroupedOption function.
    4. Greatly simplify the implementation of getOptionPred, and make
       it avoid splitting prefix options at = when that doesn't match
       a non-prefix option.

    Here's fun! It turns out that these filter functions can be internal. If they're
    internal, they shouldn't use the indirect pointer stuff. In the case of

    its contents.

    When computing live intervals for earlyclobber operands,
    we pushed the beginning of the interval back 1, so the
    interval would overlap with inputs that die.  We were
    also pushing the end of the interval back 1, though,
    which means the earlyclobber didn't overlap with other
    output operands.  Don't do this.  PR 4964.

    It's inefficient to have place the exception tables (which contain the LSDA)

    Make a new X8632_MachoTargetObjectFile TLOF implementation whose
    getSymbolForDwarfGlobalReference is smart enough to know that it
    needs to register the stub it references with MachineModuleInfoMachO,
    so that it gets emitted at the end of the file.

    Move stub emission from X86ATTAsmPrinter::doFinalization to the
    new X86ATTAsmPrinter::EmitEndOfAsmFile asmprinter hook.  The important
    thing here is that EmitEndOfAsmFile is called *after* the ehframes are
    emitted, so we get all the stubs.

    This allows us to remove a gross hack from the asmprinter where it would
    "just know" that it needed to output stubs for personality functions.
    Now this is all driven from a consistent interface.

    The testcase change is just reordering the expected output now that the
    stubs come out after the ehframe instead of before.

    This also unblocks other changes that Bill wants to make.

    Update malloc call creation code (AllocType is now the element type of the malloc, not the resulting type).

    In getMallocArraySize(), fix bug in the case that array size is the product of 2 constants.

    Extend isArrayMalloc() and getMallocArraySize() to handle case where malloc is used as char array.

    Ensure that ArraySize in LowerAllocations::runOnBasicBlock() is correct type.

    Extend Instruction::isSafeToSpeculativelyExecute() to handle malloc calls.

    Add verification for malloc calls.

    Fix a bug in sdisel switch lowering code. When it updates the phi nodes in switch successor blocks, it can introduce multiple phi operands of the same value from different blocks (and may not be on the predecessor list).

    This can be seen on CodeGen/Generic/2006-09-06-SwitchLowering.ll. But it's not known to cause any real regression (but I have added an assertion for it now).

    Add a new pass for doing late hoisting of floating-point and vector
    constants out of loops. These aren't covered by the regular LICM
    pass, because in LLVM IR constants don't require separate
    instructions. They're not always covered by the MachineLICM pass
    either, because it doesn't know how to unfold folded constant-pool
    loads. This is somewhat experimental at this point, and off by
    default.

    Do not try and sink a load whose chain result has more than one use, when

    Don't sink gep operators through phi nodes if the result would require
    more than one phi, since that leads to higher register pressure on
    entry to the phi. This is especially problematic when the phi is in

    Big change #1 for personality function references:
    Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
    fields from MAI: they aren't part of the asm syntax, they are
    related to the structure of the object file.

    To replace their functionality, add a new
    TLOF::getSymbolForDwarfGlobalReference method which asks targets
    to decide how to reference a global from EH in a pc-relative way.

    The default implementation just returns the symbol.  The default
    darwin implementation references the symbol through an indirect
    $non_lazy_ptr stub.  The bizarro x86-64 darwin specialization
    handles the weird "foo@GOTPCREL+4" hack.

    DwarfException.cpp now uses this to emit the reference to the
    symbol in the right way, and this also eliminates another
    horrible hack from DwarfException.cpp:

    -    if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))
    -      O << "-" << MAI->getPCSymbol();

    Added a variety of floating-point and SSE instructions.
    All of these do not have patterns (they're for the

    Many of the floating-point instructions will probably
    be rolled into definitions that have patterns, and may
    eventually be superseded by mdefs.  So I put them
    together and left a comment.

    Eliminate AsmPrinter::EmitExternalGlobal, inlining its (now)
    one implementation into its one caller.  This eliminates a totally
    awesome and gratuitous hack where we casted a Function* to
    GlobalVariable*.

    eliminate the PPC backend's implementation of EmitExternalGlobal
    and use PersonalityPrefix/Suffix to achieve the same effect (like
    the x86 backend).

    This changes the code generated for ppc static mode, but guess what,
    we were generating this before:

    	.byte	0x9B                                        ; Personality (indirect pcrel sdata4)
    	.long	___gxx_personality_v0-.                     ; Personality

    which is not correct! (it is not an 'indirect' reference).

    Change the marker byte for stubs from 0xcd to 0xce (another form of
    interrupt instruction, which shouldn't arise any other way).  0xcd is
    also used by JITMemoryManager to initialize the buffer to garbage,
    which means it could appear following a noreturn call even when
    that is not a stub, confusing X86CompilationCallback2.  PR 4929.

    Handle AddrMode4 for Thumb2 in rewriteT2FrameIndex.  This occurs for
    VLDM/VSTM instructions, and without this check, the code assumes that an
    offset is allowed, as it would be with VLDR/VSTR.  The asm printer,
    however, silently drops the offset, producing incorrect code.  Since the
    address register in this case is either the stack or frame pointer, the
    spill location ends up conflicting with some other stack slot or with
    outgoing arguments on the stack.

commit 72444efbd46645993821a5167411656371e995b1
Author: Dan Gohman <gohman@apple.com>
Date:   Tue Sep 15 15:58:07 2009 +0000

    When a constant's type is refined, update the constant in place
    instead of cloning and RAUWing it.

     - Make AbstractTypeUser a friend of Value so that it can offer
       its subclasses a way to update a Value's type in place. This
       is better than a universally visible setType method on Value,
       and it's sufficient for the immediate need.

     - Eliminate the constant "convert" functions. This eliminates a
       lot of logic duplication, and fixes a complicated bug where a
       constant can't actually be cloned during the type refinement
       process because some of the types that its folder needs are
       half-destroyed, being in the middle of refinement themselves.

     - Move the getValType functions from being static overloaded
       functions in Constants.cpp to be members of class template
       specializations in ConstantsContext.h. This means that the
       code ends up getting instantiated twice, however it also
       makes it possible to eliminate all "convert" functions, so
       it's not a big net code size increase. And if desired, the
       duplicate instantiations could be eliminated with some
       reorganization.

    Another try at early partial coalescing. Identity phi source copies (their sources are defined by phi join def) are coalesced. And the phi join copy is backward copy propagated into the other copies.

    Forbid arrays of function-type and structures with function-typed fields.

    While I'm there, change code that does:
      SomeTy == Type::getFooType(Context)
    into:
      SomeTy->getTypeID() == FooTyID
    to decrease the amount of useless type creation which may involve locking, etc.

    Don't pull a load through a callseq_start if the load's chain
    has multiple uses, as one of the other uses may be on a path

    Substantially speed up combiner-aa in the following ways:

    1. Switch from an std::set to a SmallPtrSet for visited chain nodes.
    2. Do not force the recursive flattening of token factor nodes, regardless of
       use count.
    3. Immediately process newly created TokenFactor nodes.

    Also, improve combiner-aa by teaching it that loads to non-overlapping offsets
    of relatively aligned objects cannot alias.

    These changes result in a >5x speedup for combiner-aa on most testcases.

    Add early coalescing to liveintervals. This is work in progress and is known to miscompute some tests. Read it at your own rish, I have aged 10 year while writing this.

    The gist of this is if source of some of the copies that feed into a phi join is defined by the phi join, we'd like to eliminate them. However, if any of the non-identity source overlaps the live interval of the phi join then the coalescer won't be able to coalesce them. The early coalescer's job is to eliminate the identity copies by partially-coalescing the two live intervals.

    Storing a set of PATypeHolders is a bad idea because their sort order will
    change as types are refined. Remove abstract types from CheckedTypes when they
    we're informed that they have been refined. The only way types get refined in
    the verifier is when later function passes start optimizing. Fixes PR4970.

    devirtualize AsmPrinter::printBasicBlockLabel since it is never overridden.
    Move GetMBBSymbol up to AsmPrinter and make printBasicBlockLabel use it so that

    X86MCInstLower::Lower should only not emit anything to OutStreamer,
    this means that it can only lower one MachineInstr to one MCInst.  To
    make this fly, we need to pull out handling of MO_GOT_ABSOLUTE_ADDRESS
    (which generates an implicit label) out of X86MCInstLower.

    Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't
    working. To support this, add an is_displayed() function to raw_ostream,
    and generalize Process::StandardOutIsDisplayed and friends in order to
    support it.

    Also, call RemoveFileOnSignal before creating a file instead of after, so
    that the file isn't left behind if the program is interrupted between when
    the file is created and RemoveFileOnSignal is called.

    While here, add a -S to llvm-extract and port it to IRReader so that it
    supports assembly input.

    not all timers it contained were destroyed.

    It's not legal to fold a load from a narrower stack slot into a wider instruction. If done, the instruction does a 64-bit load and that's not
    safe. This can happen we a subreg_to_reg 0 has been coalesced. One
    exception is when the instruction that folds the load is a move, then we
    can simply turn it into a 32-bit load from the stack slot.

    Teach lib/VMCore/ConstantFold.cpp how to set the inbounds keyword and
    how to fold notionally-out-of-bounds array getelementptr indices instead
    of just doing these in lib/Analysis/ConstantFolding.cpp, because it can
    be done in a fairly general way without TargetData, and because not all
    constants are visited by lib/Analysis/ConstantFolding.cpp. This enables
    more constant folding.

    Also, set the "inbounds" flag when the getelementptr indices are
    one-past-the-end.

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

    Added the ParseInstruction() hook for target specific assembler directives so
    that things like .word can be parsed as target specific.  Moved parsing .word
    out of AsmParser.cpp into X86AsmParser.cpp as it is 2 bytes on X86 and 4 bytes
    for other targets that support the .word directive.

    Don't hardcode the TType format size. In fact, rework the code so that it's more

    does, though.

    Believe it or not, this is a simplification. :-)

    Basically, this patch is working towards removing the hard-coded values that are
    output for the CIE. In particular, the CIE augmentation and the CIE augmentation
    size. Both of these should be calculated. In the process, I was able to make a
    bunch of code simpler.

    The encodings for the personality, LSDA, and FDE in the CIE are still not
    correct. They should be generated either from target-specific callbacks (blech!)
    or grokked from first-principles.

    remove DebugLoc from MCInst and eliminate "Comment printing" from
    the MCInst path of the asmprinter.  Instead, pull comment printing
    out of the autogenerated asmprinter into each target that uses the
    autogenerated asmprinter.  This causes code duplication into each
    target, but in a way that will be easier to clean up later when more
    asmprinter stuff is commonized into the base AsmPrinter class.

    This also fixes an xcore strangeness where it inserted two tabs
    before every instruction.

Author: Chris Lattner <sabre@nondot.org>
Date:   Wed Sep 9 20:34:59 2009 +0000

    hoist the call to processDebugLoc out of the generated
    asm printer into the "printInstruction" routine.  This
    fixes a problem where the experimental asmprinter would
    drop debug labels in some cases, and fixes issues on ppc/xcore
    where pseudo instructions like "mr" didn't get debug locs properly.

    It is annoying that this moves the call from one place into each
    target, but a future set of more invasive refactorings will fix
    that problem.

    Fix SplitCriticalEdge to properly update LCSSA form when splitting a
    loop exit edge -- new PHIs may be needed not only for the additional
    splits that are made to preserve LoopSimplify form, but also for the
    original split. Factor out the code that inserts new PHIs so that it
    can be used for both. Remove LoopRotation.cpp's code for manually
    updating LCSSA form, as it is now redundant. This fixes PR4934.

    change selectiondag to add the sign extended versions of immediate operands

    Re-apply r80926, with fixes: keep the domtree informed of new blocks
    that get created during loop unswitching, and fix SplitBlockPredecessors'
    LCSSA updating code to create new PHIs instead of trying to just move
    existing ones.

    Also, optimize Loop::verifyLoop, since it gets called a lot. Use
    searches on a sorted list of blocks instead of calling the "contains"
    function, as is done in other places in the Loop class, since "contains"
    does a linear search. Also, don't call verifyLoop from LoopSimplify or
    LCSSA, as the PassManager is already calling verifyLoop as part of
    LoopInfo's verifyAnalysis.

    instcombine transforms vector loads that are only used by
    extractelement operations into a bitcast of the pointer,
    then a gep, then a scalar load.  Disable this when the vector
    only has one element, because it leads to infinite loops in
    instcombine (PR4908).

    This transformation seems like a really bad idea to me, as it
    will likely disable CSE of vector load/stores etc and can be
    better done in the code generator when profitable.  This
    goes all the way back to the first days of packed types,
    r25299 specifically.

    I'll let those people who care about the performance of vector
    code decide what to do with this.

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

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

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

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

    Stabilize the order of live intervals in the priority_queue used by the
    linear scan reg alloc.  This fixes a problem I ran into where extracting
    a function from a larger file caused the generated code to change (masking
    the problem I was trying to debug) because the allocator behaved differently.

    This changes the results for two X86 regression checks.  stack-color-with-reg
    is improved, with one less instruction, but pr3495 is worse, with one more
    copy.  As far as I can tell, these tests were just getting lucky or unlucky,
    so I've changed the expected results.

    Include optional subclass flags, such as inbounds, nsw, etc., in the
    Constant uniquing tables. This allows distinct ConstantExpr objects
    with the same operation and different flags.

    Even though a ConstantExpr "a + b" is either always overflowing or
    never overflowing (due to being a ConstantExpr), it's still necessary
    to be able to represent it both with and without overflow flags at
    the same time within the IR, because the safety of the flag may
    depend on the context of the use. If the constant really does overflow,
    it wouldn't ever be safe to use with the flag set, however the use
    may be in code that is never actually executed.

    This also makes it possible to merge all the flags tests into a single test.

    Replace ocamlc tests with ocamlopt tests since they're less noisy.

    There's a bug with ocamlc that uses "char*" instead of "const char*" for
    global string variables. This causes g++ to be very noisy when linking
    ocamlc programs. That's why the ocaml test used to cat to /dev/null.
    ocamlopt doesn't have this problem, so we can get rid of the >/dev/null,
    which may obscure some problems.

    Remove the API for creating ConstantExprs with the nsw, nuw, inbounds,
    and exact flags. Because ConstantExprs are uniqued, creating an
    expression with this flag causes all expressions with the same operands
    to have the same flag, which may not be safe. Add, sub, mul, and sdiv
    ConstantExprs are usually folded anyway, so the main interesting flag
    here is inbounds, and the constant folder already knows how to set the
    inbounds flag automatically in most cases, so there isn't an urgent need
    for the API support.

    This can be reconsidered in the future, but for now just removing these
    API bits eliminates a source of potential trouble with little downside.

    Make ImmutableMap/ImmutableSet quicker by only canonicalizing the tree after an
    Add or Remove operation complete, and not while building the intermediate tree.
    This trades a little bit more memory usage for less accesses to the FoldingSet.  On a benchmark for the clang static analyzer, this shaves off another 13% of execution time when using field/array sensitivity.

    Overhaul the TwoAddressInstructionPass to simplify the logic, especially
    for the complicated case where one register is tied to multiple destinations.
    This avoids the extra scan of instruction operands that was introduced by
    my recent change.  I also pulled some code out into a separate
    TryInstructionTransform method, added more comments, and renamed some
    variables.

    Besides all those changes, this takes care of a FIXME in the code regarding
    an assumption about there being a single tied use of a register when
    converting to a 3-address form.  I'm not aware of cases where that assumption
    is violated, but the code now only attempts to transform an instruction,
    either by commuting its operands or by converting to a 3-address form,
    for the simple case where there is a single pair of tied operands.

    Fixed a few problems with vector shifts
      - when transforming a vector shift of a non-immediate scalar shift amount, zero
        extend the i32 shift amount to i64 since the vector shift reads 64 bits
      - when transforming i16 vectors to use a vector shift, zero extend i16 shift amount
      - improve the code quality in some cases when transforming vectors to use a vector shift

    Add a -disable-16bit flag and associated support for experimenting with
    disabling the use of 16-bit operations on x86. This doesn't yet work for
    inline asms with 16-bit constraints, vectors with 16-bit elements,
    trampoline code, and perhaps other obscurities, but it's enough to try
    some experiments.

    Removed the non-target independent AsmToken::Register enum constant
    from MCAsmLexer.h in preparation of supporting other targets.  Changed the
    X86AsmParser code to reflect this by removing AsmLexer::LexPercent and looking
    for AsmToken::Percent when parsing in places that used AsmToken::Register.
    Then changed X86ATTAsmParser::ParseRegister to parse out registers as an
    AsmToken::Percent followed by an AsmToken::Identifier.

    In C++, code is not allowed to call main.  In C it is, this
    simplifylibcalls optimization is thus valid for C++ but not C.
    It's not important enough to worry about for C++ apps, so just
    remove it.

    Set the 'cached digest' flag after computing the digest for an
    ImutAVLTree.  This was accidentally left out, and essentially caused
    digest caching to be ignored in ImmutableMap and ImmutableSet (this
    bug was detected from shark traces that showed ComputeDigest was in
    the hot path in the clang static analyzer).

    This reduces the running time of the clang static analyzer on an
    example benchmark by ~32% for both RegionStore (field-sensitivty) and
    BasicStore (without field-sensitivity).

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

    Preparation for Optimal Edge Profiling:
    Optimal edge profiling is only possible when blocks with no predecessors get an
    virtual edge (BB,0) that counts the execution frequencies of this
    function-exiting blocks.
    This patch makes the necessary changes before actually enabling optimal edge profiling.

    for sanity.  This didn't turn up any bugs.

    Change CallGraphNode to maintain its "callsite" information in the
    call edges list as a WeakVH instead of as an instruction*.  This fixes
    a broad class of dangling pointer bugs, and makes CallGraph have a number
    of useful invariants again.  This fixes the class of problem indicated
    by PR4029 and PR3601.

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

    Clean up LSDA name generation and use for SJLJ exception handling. This
    makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
    and making it a GV available for reference would be even better, but is
    beyond the scope of what I'm looking to solve at this point.

    Objective C++ code could generate function names that broke the previous
    scheme. This fixes that.

    Extend the ValuesAtScope cache to cover all expressions, not just
    SCEVUnknowns, as the non-SCEVUnknown cases in the getSCEVAtScope code
    can also end up repeatedly climing through the same expression trees,
    which can be unusably slow when the trees are very tall.

    Also, add a quick check for SCEV pointer equality to the main
    SCEV comparison routine, as the full comparison code can be expensive
    in the case of large expression trees.

    These fix compile-time problems in some pathlogical cases.
