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

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

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

    r112986 fixed a latent bug exposed by the above.

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

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

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

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

    Finish converting the rest of the NEON VLD instructions to use pseudo-
    instructions prior to regalloc.  Since it's getting a little close to
    the 2.8 branch deadline, I'll have to leave the rest of the instructions
    handled by the NEONPreAllocPass for now, but I didn't want to leave half
    of the VLD instructions converted and the other half not.

    Fix cmake build without native target selected.

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

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

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

    reapply 112894:

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

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

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

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

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

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

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

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

    - Add patterns to match the following MMX builtins:

       * __builtin_ia32_vec_init_v8qi
       * __builtin_ia32_vec_init_v4hi
       * __builtin_ia32_vec_init_v2si
       * __builtin_ia32_vec_ext_v2si

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

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

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

    now is generated as:

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

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

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

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

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

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

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

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

    We generate this:

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

    while gcc generates this:

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

    Scandalous really!

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

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

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

    Track liveness of unallocatable, unreserved registers in machine DCE.

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

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

    Unreserved, unallocatable registers can not be used for virtual registers, but

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

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

    Improve virtual frame base register allocation heuristics.

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

    More Chris-inspired JumpThreading fixes: use ConstantExpr to correctly constant-fold undef, and be more careful with its return value.
    This actually exposed an infinite recursion bug in ComputeValueKnownInPredecessors which theoretically already existed (in JumpThreading's

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

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

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

    two changes:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    after:

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

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

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

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

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

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

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

    We now produce:

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

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

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

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

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

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

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

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

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

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

    we now generate:

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

    instead of:

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

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

    into all nice vector operations:

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

    instead of icky integer operations:

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

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

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

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

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

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

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

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

Author: Chris Lattner <sabre@nondot.org>

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

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

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

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

    into:

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

    on x86-64, instead of:

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

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

    Fix the msvs 2010 build.

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

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

    optimize bitcast(trunc(bitcast(x))) where the result is a float and 'x'
    is a vector to be a vector element extraction.  This allows clang to

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

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

commit be815c0090189c08f618f74365954c1ceea40312
Author: Bill Wendling <isanbard@gmail.com>

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

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

    and:

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

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

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

      ~x + 1 = -x

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

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

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

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

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

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

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

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

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

    Now compiles into:

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

    previously it compiled into:

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

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

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

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

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

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

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

    Create the new linker type "linker_private_weak_def_auto".

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

    Introduce a new temporary MDNode concept. Temporary MDNodes are

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

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

    Fix the msvc 2010 build.

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

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

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

    Revert r111394. It was too aggressive.

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

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

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

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

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

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

commit 94977adb6c5e67c85d8810d72aab836778a979dc
Author: Jim Grosbach <grosbach@apple.com>
Date:   Wed Aug 18 17:57:37 2010 +0000

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

    Fix the rest of rdar://8318441 which happens when a raw_fd_ostream
    (e.g. errs()) fails in close() due to (e.g.) a broken pipe.  As
    previously written, the had_error() flag would get set and then
    the raw_ostream dtor would report a fatal error.  There is nothing
    the client can do about this and we have no way to report the error,
    so just eat it.

    Tweak IVUsers' concept of "interesting" to exclude add recurrences
    where the step value is an induction variable from an outer loop, to
    avoid trouble trying to re-expand such expressions. This effectively
    hides such expressions from indvars and lsr, which prevents them
    from getting into trouble.

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

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

    PHI elimination shouldn't require machineloopinfo since it's used at -O0. Move the requirement to LiveIntervalAnalysis instead. Note this does not change the number of times machineloopinfo is computed.

commit cb488dcc614eff2ed801c3799918dc5e00ae82c8
Author: Jim Grosbach <grosbach@apple.com>
Date:   Tue Aug 17 18:13:53 2010 +0000

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

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

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

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

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

    To create a copy of a SmallVector with an element removed from the

    elements and then doing an erase on the middle of the result. These
    are SmallVectors, so we shouldn't expect to hit dynamic allocation
    in the common case.

    Instead of having CollectSubexpr's categorize operands as interesting or

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

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

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

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

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

    Handle an empty dupli.

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

    Example:

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

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

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

    - Make sure MOV[AU]PS instructions are only selected when SSE1 is enabled, and duplicate the patterns to match AVX.

    Implement single block splitting.

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

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

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

    so all avx intrinsics which aren't mapped to their own built-ins but to
    shufflevector calls can be codegen'd. This is the first (baby) step, support
    building zeroed vectors.

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

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

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

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

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

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

    Consider this code snippet:

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

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

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

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

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

    Now we generate this, which looks optimal to me:

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

    Add AVX matching patterns to Packed Bit Test intrinsics.

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

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

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

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

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

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

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

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

    Implement register class inflation.

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

    reserved, not available for general allocation. This eliminates all the

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

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

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

    ARMBaseRegisterInfo::hasFP() has been broken for a while now. :-(
    This will always be false before PEI:
    (DisableFramePointerElim(MF) && MFI->adjustsStack())
    Which means it's going to make r11 available as a general purpose register even
    if -disable-fp-elim is specified. It's working on Darwin only because r7 is

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

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

    Don't try to verify LiveIntervals for physical registers.

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

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

    Without this what was happening was:

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

    Add the Optimize Compares pass (disabled by default).

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

       sub r1, 1
       cmp r1, 0
       bz  L1

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

    Move all the logic for function attributes and call attributes out of the
    AliasAnalysis base class and into BasicAliasAnalyais. This avoids confusion
    about where such logic is happening when there are other AliasAnalysis
    implementations present.

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

    - Are all live ranges continually reachable from their def?

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

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

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

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

    Use indirect calls in PowerPC JIT.

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

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

    Add support for the FLT_ROUNDS_ node now that the FPSCR is exposed.

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

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

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

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

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

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

    exactly what bugpoint expected it to do.

    There was also only one user of

    make BlockExtractorPass read BlockFile.

    This fixes bugpoint's block extraction.

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

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

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

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

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

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

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

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

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

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

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

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

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

    Patches welcome.

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

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

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

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

    This fixes MallocBench/gs for thumb2 -O0.

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

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

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

    For:

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

    We get:

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

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

    Instead of:

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

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

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

    This fixes PR7713.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    This also handles SSE-sized vectors of floating point.

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

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

    Add new RegionInfo pass.

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

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

    This fixes rdar://8213383. No test case since it's not possible to come up with a suitable small one.

    Fix a couple issues with Win64 ABI

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

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

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

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

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

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

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

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

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

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

    Beginning SplitKit - utility classes for live range splitting.

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

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

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

commit 14c9160bfe1acc03b9a4de19947bd0b33019dec6
Author: Evan Cheng <evan.cheng@apple.com>
Date:   Mon Jul 19 18:47:01 2010 +0000

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

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

    it should set the jump table encloding the EK_Inline. This prevents

    Consider this function:

      void foo() { __builtin_unreachable(); }

    It will output the following on Darwin X86:

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

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

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

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

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

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

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

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

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

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

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

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

    Lack of this attribute was preventing the assembler from emitting
    multibyte noops instructions for templates (and inlines, and other
    coalesced stuff) and was causing the assembler to mismatch .o files.

    This fixes rdar://8018335

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

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

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

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

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

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

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

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

    used for argument passing.

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

    rotate CallInst operands

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

    this ordering is now consistent with InvokeInst

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

    Convert the last use of getPhysicalRegisterRegClass and remove it.

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

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

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

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

    RISC architectures get their memory operand folding for free.

    Remove obsolete README_SSE note.

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

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

    The same applies to andps -> pand.

    Convert uses of getPhysicalRegisterRegClass in VirtRegRewriter.cpp.

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

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

      argument, getCallFrameTypeAlignment would return 4 for doubles on ARM for
      example.
    * The getTransientStackAlignment method. It is possible for an architecture to
      have argument less aligned than what we maintain the stack pointer.

    The remaining copyRegToReg calls actually check the return value (shock!), so we

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

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

    Based on a patch by Rafael Espíndola.

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

    We support:

      FpSET_ST0
      INLINEASM

      FpSET_ST0
      FpSET_ST1
      INLINEASM

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

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

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

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

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

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

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

    Added a support for inserting new MBBs into the numbering.

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

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

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

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

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

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

    Teach the x86 floating point stackifier to handle COPY instructions.

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

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

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

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

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

commit 5a506fc3877d2d37eb79a62e9de2146e5f716a67
Author: Duncan Sands <baldrick@free.fr>
Date:   Wed Jul 7 07:48:00 2010 +0000

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

    Be more forgiving when calculating alias interference for physreg coalescing.

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

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

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

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

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

    You have several options to update your code:

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

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

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

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

    instead of:

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

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

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

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

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

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

    You have several options to update your code:

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

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

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

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

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

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

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

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

    Rematerialize as much as possible before inserting spills and reloads.

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

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

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

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

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

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

    You have several options to update your code:

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

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

    Objective-C metadata types which should be marked as "weak", but which the

    Objective-C.

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

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

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

    Currently only supported on Darwin platforms.

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

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

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

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

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

    please refer to this thread on llvm-dev:

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

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

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

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

    Begin implementation of an inline spiller.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    The change relative to the previous patch is:

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

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

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

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

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

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

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

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

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

    This fixes PR7312.

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

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

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

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

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

    In GenerateReassociations, don't bother thinking about individual
    SCEVUnknown values which are loop-variant, as LSR can't do anything
    interesting with these values in any case. This fixes very slow compile

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

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

    Part of the continuing work for rdar://7797940, making ARM code-gen unaffected
    by the presence of debug information.

    but since -relocation-model=static doesn't work on Darwin

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

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

    something a bit too convoluted.

    This second attempt fixes some crashes that only occurred Linux.

    Verify that VNI kills are pointing to existing instructions.

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

    Eliminate the other half of the BRCOND optimization, and update

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

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

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

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

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

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

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

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

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

    Gold has no notion of bitcode and native search directories, so instead it has
    an API where the plugin can instruct it to look for the libraries it is passing
    to it. This patch uses that API.

    Fix a tblgen bug.

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

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

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

    into the same node, but with different non-memory operands, we need to replace
    the memory operands after it's finished morphing.

    Some targets don't require the fencing MEMBARRIER instructions surrounding
    atomic intrinsics, either because the use locking instructions for the
    atomics, or because they perform the locking directly. Add support in the
    DAG combiner to fold away the fences.

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

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

    This does not affect codegen much because SUBREG_TO_REG is only used by X86 and
    X86 does not use the register scavenger, but it prevents verifier errors.

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

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

    instead of this:

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

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

    uses it, for use in code which doesn't want a CopyFromReg even

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

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

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

    This is not yet enabled.

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

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

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

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

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

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

    Evan, please review!

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

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

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

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

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

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

    Create a more targeted fix for not sinking instructions into a range where it
    will conflict with another live range. The place which creates this scenerio is

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

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

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

    Avoid processing early clobbers twice in RegAllocFast.

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

    Add CoalescerPair helper class.

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

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

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

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

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

    check that we no longer emit the unnecessary subreg moves.

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

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

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

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

    Avoid many "variable 'Sub' set but not used [-Wunused-but-set-variable]" warnings
    with gcc-4.6.  The warning is wrong, since Sub *is* used (perhaps gcc is confused
    because the use of Sub is constant folded away?), but since it is trivial to avoid,
    and massively reduces the amount of warning spew, just workaround the wrong warning.

    It's an error to translate this:

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

    into this:

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

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

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

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

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

      elements are legal
    - the Neon shuffle instructions do not support 64-bit elements, but we were
      not checking for that before lowering shuffles to use them
    - remove some 64-bit element vduplane patterns that are no longer needed

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

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

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

    Don't preserve all symbols in a .so and instead trust gold to know what is
    needed. The result is that now we are able to drop unnecessary symbol from
    shared libraries.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    will reMaterialize(%reg3333, bar) like this:

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

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

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

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

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

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

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

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

    Also, close the raw_ostream before checking for errors so that any

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

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

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

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

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

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

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

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

    Okay, bear with me here...

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

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

    2:  g = y;

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

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

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

    fmul %st(0), %st

    into this:

    fmul %st(0)

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

    fmul %st(1), %st

    that llvm-mc did not assemble.

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

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

    Then I'll remove NumberHack entirely.

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

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

    Recognize more BUILD_VECTORs and VECTOR_SHUFFLEs that can be implemented by
    copying VFP subregs.  This exposed a bunch of dead code in the *spill-q.ll
    tests, so I tweaked those tests to keep that code from being optimized away.

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

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

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

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

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

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

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

    This happens when spilling the registers produced by REG_SEQUENCE:

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

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

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

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

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

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

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

    Add support for partial redefs to the fast register allocator.

    A partial redef now triggers a reload if required. Also don't add
    <imp-def,dead> operands for physical superregisters.

    Kill flags are still treated as full register kills, and <imp-use,kill> operands
    are added for physical superregisters as before.

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

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

      %reg1024:6 = OP

    Unless the register is fully clobbered:

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

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

    When expanding a vector_shuffle, the element type may not be legal and may
    need to be promoted.  The BUILD_VECTOR and EXTRACT_VECTOR_ELT nodes generated

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    Calculate liveness on the fly for local registers.

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

    This makes the fast allocator independent of incoming kill flags.

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

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

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

    After REG_SEQUENCE is eliminated, we are left with:

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

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

    SystemZ really does mean "has calls" and not just "adjusts stack." Go ahead and
    replace the check with the appropriate predicate. Modify the testcase to reflect

    allocated by the calling fuction.)

    XFAIL the test I added with vg_leak, apparently it is the first and only llc
    -filetype=obj test, and -filetype=obj leaks a few objects. Added a FIXME, we

    Fix an embarrassing runtime regression for RegAllocFast.

    This loop is quadratic in the capacity for a DenseMap:

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

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

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

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

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

    updated support for the COFF .linkonce

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

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

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

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

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

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

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

    Mostly rewrite RegAllocFast.

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

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

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

    Extended the edis "IsBranch" property to call
    instructions as well.  Added support for checking
    this to the llvm-mc tester as well.

commit 1f76d011f65a657f173de08f9d4e8d1c82682bd7

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

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

    Fix PR6875:

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

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

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

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

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

    into:

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

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

    This fixes rdar://7896024

    Add llvm::sys::RunInterruptHandlers(), which runs the registered SIGINT cleanup
    stuff.

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

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

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

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

    Remove VLD1q and VST1q for reloading and spilling Q registers. Just use VLD1q64 / VST1q64 and reference sub-registers.

    Overhauled llvm/clang docs builds. Closes PR6613.

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

    *** PRE-PATCH ISSUES ADDRESSED

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

    *** IMPROVEMENTS

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

    decoded correctly.

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

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

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

    that was causing PC-relative branch targets to be
    evaluated incorrectly.  Also added support for
    checking operand values to the llvm-mc tester.

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

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

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

    Before:

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

    After:

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

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

    This is not exposed through anything in the compiler yet.

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

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

commit 4de3e21e7ab803ac4a90f74a8730264630b91766

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

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

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

commit 56aac4fe4246be908ba4f892eae2ff5e2c578d1f
Author: Daniel Dunbar <daniel@zuster.org>

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

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

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

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

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

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

    SimplifyICmpOperands will simplify such cases to EQ or NE. This makes
    the correcntess of the code independent on SimplifyICmpOperands doing
    certain simplifications.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    This instruction would crash the pass:

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

    Now it doesn't.

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

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

    When checking whether the special handling for an addrec increment which
    doesn't dominate the header is needed, don't check whether the increment
    expression has computable loop evolution. While the operands of an

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

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

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

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

    Add a new utility function SimplifyICmpOperands. Much of this code is
    refactored out of ScalarEvolution::isImpliedCond, which will be updated
    to use this new utility routine soon.

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

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

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

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

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

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

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

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

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

Author: Chris Lattner <sabre@nondot.org>

    when inlining something like this:

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

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

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

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

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

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

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

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

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

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

Author: Jakob Stoklund Olesen <stoklund@2pi.dk>
Date:   Wed Apr 21 18:02:42 2010 +0000

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

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

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

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

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

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

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

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

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

    Now we produce:

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

    	shlb	$2, %dl
    	movzbl	%dl, %edx
    	movl	%esi, (%rdi,%rdx,4)
    	movl	%esi, 8(%rdi,%rdx,4)
    	movl	%esi, 4(%rdi,%rdx,4)
    	movl	%esi, 12(%rdi,%rdx,4)
    	incb	%r8b
    	decb	%al
    	movb	%r8b, %dl

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

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

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

    A testcase would be huge and fragile, sorry.

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

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

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

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

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

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

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

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

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

    more efficient access to operands and callee, faster callgraph-construction,
    smaller compiler binary

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

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

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

    Avoid sinking machine instructions into a loop.

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

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

    Generalize the EXPORTED_SYMBOL_FILE concept in the Makefiles to work with
    native linking export files, including running sed to prepend underscores
    on darwin, and make use of it in libLTO and libEnhancedDisassembly.

    Remove the leading underscores from library export files so that they

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

    enhance the load/store narrowing optimization to handle a

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

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

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

            movl    %eax, 36(%rdi)

    instead of:

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

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

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

Author: Johnny Chen <johnny.chen@apple.com>
Date:   Wed Apr 14 21:03:13 2010 +0000

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

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

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

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

    Teach MachineSinking to handle easy critical edges.

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

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

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

    IndVarSimplify will now recognize that i is always less than n inside

    Micro-optimization:

    If we have this situation:

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

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

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

    This testcase shows an example of this:

    float func(float x, float y) {
        double product = (double)x * y;
        if (product == 0.0)

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

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

    Rewrite the overflow checking in the get{Signed,Unsigned}Range code for
    AddRecs so that it checks for overflow in the computation that it is
    performing, rather than just checking hasNo{Signed,Unsigned}Wrap, since
    those flags are for a different computation. This fixes a bug that

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

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

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

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

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

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

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

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

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

    convert a report_fatal_error that I was able to trigger into a nice error

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

    introduce a new recoverable error handling API to LLVMContext
    and use it in one place in inline asm handling stuff.  Before
    we'd generate this for an invalid modifier letter:

    $ clang asm.c -c -o t.o
    fatal error: error in backend: Invalid operand found in inline asm: 'abc incl    ${0:Z}'
    INLINEASM <es:abc incl    ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>

    Now we generate this:

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

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

commit becedf6330883fc05fad88ba95fca8e466742397
Author: Dan Gohman <gohman@apple.com>
Date:   Wed Apr 7 22:27:08 2010 +0000

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

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

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

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

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

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

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

    No functionality change.

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

    Fix PR6696 and PR6663

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

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

    Revise debug info machinery to digest nested functions and classes.

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

    add .o file writing for inline asm in llc.  Here's a silly
    demo:

    $ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
    <inline asm>:1:2: error: unrecognized instruction
    	abc incl    %eax
    	^
    LLVM ERROR: Error parsing inline asm

    Only problem seems to be that the parser finalizes OutStreamer
    at the end of the first inline asm, which isn't what we want.
    For example:

    $ cat asm.c
    int foo(int X) {
     __asm__ ("incl    %0" : "+r" (X));
     return X;
    }
    $ clang asm.c -S -o - -emit-llvm | llc
    ...
    	subq	$8, %rsp
    	movl	%edi, (%rsp)
    	movl	%edi, %eax
    	## InlineAsm Start
    	incl    %eax
    	## InlineAsm End
    	movl	%eax, (%rsp)
    	movl	%eax, 4(%rsp)
    	addq	$8, %rsp
    	ret
    $ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
    $ otool -tv t.o
    t.o:
    (__TEXT,__text) section
    _foo:
    0000000000000000	subq	$0x08,%rsp
    0000000000000004	movl	%edi,(%rsp)
    0000000000000007	movl	%edi,%eax
    0000000000000009	incl	%eax
    $

    don't stop at inc!

    fix a really nasty bug that Evan was tracking in SCCP.  When resolving
    undefs in branches/switches, we have two cases: a branch on a literal
    undef or a branch on a symbolic value which is undef.  If we have a
    literal undef, the code was correct: forcing it to a constant is the
    right thing to do.

    If we have a branch on a symbolic value that is undef, we should force
    the symbolic value to a constant, which then makes the successor block
    live.  Forcing the condition of the branch to being a constant isn't
    safe if later paths become live and the value becomes overdefined.  This
    is the case that 'forcedconstant' is designed to handle, so just use it.

    This fixes rdar://7765019 but there is no good testcase for this, the
    one I have is too insane to be useful in the future.

    hopefully sate the clang self host build, which is apparently
    instantiating some folding set stuff that GCC isn't, requiring
    some types to not be incomplete.

    I don't know if clang is right or wrong, but unbreaking the
    bot is goodness.  Here's the broken build:

    The disassembler impl. of MCDisassembler::getInstruction() was using the pattern
      uint32_t insn;
      MemoryObject.readBytes(Address, 4, (uint8_t*)&insn, NULL)

    to read 4 bytes of memory contents into a 32-bit uint variable.  This leaves the
    interpretation of byte order up to the host machine and causes PPC test cases of
    arm-tests, neon-tests, and thumb-tests to fail.  Fixed to use a byte array for
    reading the memory contents and shift the bytes into place for the 32-bit uint
    variable in the ARM case and 16-bit halfword in the Thumb case.

    Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field.

    When a target instruction wants to set target-specific flags, it should simply
    set bits in the TSFlags bit vector defined in the Instruction TableGen class.

    This works well because TableGen resolves member references late:

    class I : Instruction {
      AddrMode AM = AddrModeNone;
      let TSFlags{3-0} = AM.Value;
    }

    let AM = AddrMode4 in
    def ADD : I;

    TSFlags gets the expected bits from AddrMode4 in this example.

    Momentous day: remove the "O" member from AsmPrinter.  Now all
    "asm printering" happens through MCStreamer.  This also
    Streamerizes PIC16 debug info, which escaped my attention.

    This removes a leak from LLVMTargetMachine of the 'legacy'
    output stream.

    add integer overflow check for the fp induction variable
    checker.  Amusingly, we already had tests that we should
    have rejects because they would be miscompiled in the
    testsuite.

    The remaining issue with this is that we don't check that
    the branch causes us to exit the loop if it fails, so we
    don't actually know if we remain in bounds.

    Add special case bitcode support for DebugLoc.  This avoids
    having the bitcode writer materialize mdnodes for all the
    debug location tuples when writing out the bc file and
    stores the information in a more compact form.  For example,
    the -O0 -g bc file for combine.c in 176.gcc shrinks from
    739392 to 512096 bytes.

    This concludes my planned short-term debug info work.

    Add some switches helpful for debugging:

    -print-before=<Pass Name>

    Dump IR before running pass <Pass Name>.

    -print-before-all

    Dump IR before running each pass.

    -print-after-all

    Dump IR after running each pass.

    These are helpful when tracking down a miscompilation.  It is easy to
    get IR dumps and do diffs on them, etc.

    To make this work well, add a new getPrinterPass API to Pass so that
    each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass
    suitable for dumping out the kind of object the Pass works on.

    Switch the code generator (except the JIT) onto the new DebugLoc

    file/line/col tuples from -O0 -g codegen.

    This remove the old DebugLoc class, making it a typedef for DebugLoc,
    I'll rename NewDebugLoc next.

    I didn't update the JIT to use the new apis, so it will continue to
    work, but be as slow as before.  Someone should eventually do this
    or, better yet, rip out the JIT debug info stuff and build the JIT
    on top of MC.

    These are helpful when tracking down a miscompilation.  It is easy to
    get IR dumps and do diffs on them, etc.

    To make this work well, add a new getPrinterPass API to Pass so that
    each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass
    suitable for dumping out the kind of object the Pass works on.

    Dump IR before running pass <Pass Name>.

    -print-before-all

    Dump IR before running each pass.

    Dump IR after running each pass.

    These are helpful when tracking down a miscompilation.  It is easy to

    This requires a corresponding clang/llvm-gcc change which
    I'll try to commit as simultaneously as possible.

    Fix sdisel memcpy, memset, memmove lowering:
    1. Makes it possible to lower with floating point loads and stores.
    2. Avoid unaligned loads / stores unless it's fast.
    3. Fix some memcpy lowering logic bug related to when to optimize a
       load from constant string into a constant.
    4. Adjust x86 memcpy lowering threshold to make it more sane.
    5. Fix x86 target hook so it uses vector and floating point memory
       ops more effectively.

    Switch the representation of the location in instruction from
    being a TrackingVH<MDNode> to a NewDebugLoc, shrinking
    sizeof(Instruction) a lot, and providing clients the ability
    to deal with locations in terms of NewDebugLoc instead of
    having to deal with Metadata.  This is still fully compatible
    with all clients that *do* use MDNodes for everything of
    course.

    No functionality change.

    Add a new "NewDebugLoc" class which will eventually replace DebugLoc,
    and will replace the 'DbgInfo' member in Instruction.

    The benefit of NewDebugLoc is that it is compact (8 bytes vs 12/24
    bytes for the DbgInfo member in Instruction on a 32/64 bit system),
    it means that we will end up not having to allocate MDNodes to
    represent the "DILocations" in common cases of -O0 -g, and it is
    much more efficient to get things out of than the MDNode.

    Fix a nasty dangling-pointer heisenbug that could
    generate wrong code pretty much anywhere AFAICT.
    A case that hits the bug reproducibly is impossible,
    but the situation was like this:
    Addr = ...
    Store -> Addr
    Addr2 = GEP , 0, 0
    Store -> Addr2
    Handling the first store, the code changed replaced Addr
    with a sunkaddr and deleted Addr, but not its table
    entry.  Code in OptimizedBlock replaced Addr2 with a
    bitcast; if that happened to reuse the memory of Addr,
    the old table entry was erroneously found when handling
    the second store.

    they are faster than the old apis, particularly when

    Fix a major source of compile-time slowness at -O0 -g by optimizing
    the storage of !dbg metadata kinds in the instruction themselves.
    The on-the-side hash table works great for metadata that not-all
    instructions get, or for metadata that only exists when optimizing.
    But when compile-time is everything, it isn't great.

    I'm not super thrilled with the fact that this plops a TrackingVH in
    Instruction, because it grows it by 3 words.  I'm investigating
    alternatives, but this should be a step in the right direction in any
    case.

Author: Edwin Török <edwintorok@gmail.com>
Date:   Tue Mar 30 10:08:26 2010 +0000

    Introduce another Reset() method in BumpPtrAllocator that calls a destructor
    on all objects it has allocated, if they are all of the same size and alignment.
    Use this to destruct all VNInfos allocated in LiveIntervalAnalysis (PR6653).

    valnos is not reliable for this purpose, as seen in r99400
    (which still leaked, and sometimes caused double frees).

    A more general (and simpler!) implementation of r99671. It performs a similar
    transform. I.e., if a clean-up eh.selector call dominates the invoke of an
    _Unwind_Resume_or_Rethrow, then we convert the eh.selector into a
    catch-all. This patch, however, uses the DominatorTree information, and doesn't
    go through the whole rigmarole of starting at the eh.exception call, finding the
    corresponding URoR and eh.selector calls, and trying to trace through any number
    of instruction types to get to them.

    "the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions:
    -in vararg handling, registers are marked to be live, to not confuse the register scavenger
    -function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the register scavenger emergency spill slot, which is not used as there is no stack."

Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Mar 29 02:02:45 2010 +0000

    Switch pattern sorting predicate from stable sort -> sort, it
    doesn't need to be stable because the patterns are fully ordered.

    Add a first level sort predicate that orders patterns in this
    order:  1) scalar integer operations 2) scalar floating point
    3) vector int 4) vector float.  This is a trivial sort on their
    top level pattern type so it is nice and transitive.  The
    benefit of doing this is that simple integer operations are
    much more common than insane vector things and isel was trying
    to match the big complex vector patterns before the simple
    ones because the complexity of the vector operations was much
    higher.  Since they can't both match, it is best (for compile
    time) to try the simple integer ones first.

    This cuts down the # failed match attempts on real code by
    quite a bit, for example, this reduces backtracks on crafty
    (as a random example) from 228285 -> 188369.

    Check in a (disabled) failed attempt to improve the ordering of
    patterns within the generated matcher.  This works great except
    that the sort fails because the relation defined isn't

    Add NVTBLFrm to represent A8.6.406 VTBL, VTBX Vector Table Lookup Instructions.
    These instructions use byte index in a control vector (M:Vm) to lookup byte
    values in a table and generate a new vector (D:Vd).  The table is specified via
    a list of vectors, which can be:

    {Dn}
    {Dn D<n+1>}
    {Dn D<n+1> D<n+2>}
    {Dn D<n+1> D<n+2> D<n+3>}

    Fix use-of-uninitialized value when RWX memory can't be allocated (PR6701).

    SELinux doesn't allow 'execmem', returning MAP_FAILED and 'Permission denied'
    for mmap or RWX memory. In this case AllocateRWX was returning a MemoryBlock
    with uninitialized fields, which sometimes caused crashes.

    This patch initializes MemoryBlock fields to 0, so that the RWX-failure check
    works.
    It doesn't fix the SELinux 'execmem' issues though (the JIT will not work when
    SELinux is in enforcing mode).

    finally remove the immAllOnesV_bc/immAllZerosV_bc patterns
    and those derived from them.  These are obnoxious because
    they were written as: PatLeaf<(bitconvert).  Not having an

    count matching up with what was required (in this case,
    bitconvert always requires an operand!)

    teach tblgen to allow patterns like (add (i32 (bitconvert (i32 GPR))), 4),
    transforming it into (add (i32 GPR), 4).  This allows us to write type
    generic multi patterns and have tblgen automatically drop the bitconvert
    in the case when the types align.  This allows us to fold an extra load
    in the changed testcase.

    CompleteMatch or MorphNodeTo operation to be the same size as the
    thing we're matching.  this means that if you match (add GPR, GPR)
    with an instruction that produces a normal result and a flag that
    we now trim the result in tblgen instead of having to do it
    dynamically.  This exposed a bunch of inconsistencies in result
    counting that happened to be getting lucky since the days of the
    old isel.

    If we mark clean-ups as clean-ups, then it could break when inlining through an
    'invoke' instruction. You will get a situation like this:

    bb:
      %ehptr = eh.exception()
      %sel = eh.selector(%ehptr, @per, 0);

    ...

    bb2:
      invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad

    lpad:
      ...

    The unwinder will see the %sel call as a clean-up and, if it doesn't have a
    catch further up the call stack, it will skip running it. But there *is* another
    catch up the stack -- the catch for the %lpad. However, we can't see that. This
    is fixed in code-gen, where we detect this situation, and convert the "clean-up"
    selector call into a "catch-all" selector call. This gives us the correct
    semantics.

    Add N2RegVShLFrm and N2RegVShRFrm formats so that the disassembler can easily
    dispatch to the appropriate routines to handle the different interpretations of
    the shift amount encoded in the imm6 field.  The Vd, Vm fields are interpreted
    the same between the two, though.

    See, for example, A8.6.367 VQSHL, VQSHLU (immediate) for N2RegVShLFrm format and
    A8.6.368 VQSHRN, VQSHRUN for N2RegVShRFrm format.

    Feel free to LOL at the -before numbers, if you like.

    I am a little surprised we make more than 2 relaxation passes. It's pretty
    trivial for us to do relaxation out-of-order if that would give a speedup.

    Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain crossings.

    On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a register
    in a different domain than where it was defined. Some instructions have
    equvivalents for different domains, like por/orps/orpd.

    The SSEDomainFix pass tries to minimize the number of domain crossings by
    changing between equvivalent opcodes where possible.

    This is a work in progress, in particular the pass doesn't do anything yet. SSE
    instructions are tagged with their execution domain in TableGen using the last
    two bits of TSFlags. Note that not all instructions are tagged correctly. Life
    just isn't that simple.

    The SSE execution domain issue is very similar to the ARM NEON/VFP pipeline
    issue handled by NEONMoveFixPass. This pass may become target independent to
    handle both.

    Change tblgen to emit FOOISD opcode names as two
    bytes instead of one byte.  This is important because
    we're running up to too many opcodes to fit in a byte
    and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE
    making the numbering sparse.  This just bites the
    bullet and bloats out the table.  In practice, this
    increases the size of the x86 isel table from 74.5K
    to 76K.  I think we'll cope :)

    This fixes rdar://7791648

    Fix evil TableGen bug in template parameters with defaults.

    If a TableGen class has an initializer expression containing an X.Y subexpression,
    AND X depends on template parameters,
    AND those template parameters have defaults,
    AND some parameters with defaults are beyond position 1,
    THEN parts of the initializer expression are evaluated prematurely with the default values when the first explicit template parameter is substituted, before the remaining explicit template parameters have been substituted.

    eliminate a bunch more parallels now that scheduling
    handles dead implicit results more aggressively.  More
    to come, I think this is now just a data entry problem.

    git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99486 91177308-0d34-0410-b5e6-96231b3b80d8

    Make the NDEBUG assertion stronger and more clear what is
    happening.

    Enhance scheduling to set the DEAD flag on implicit defs
    more aggressively.  Before, we'd set an implicit def operand
    to dead if it were present in the SDNode corresponding to
    the machineinstr but had no use.  Now we do it in this case
    AND if the implicit def does not exist in the SDNode at all.

    This exposes a couple of problems: one is the FIXME, which
    causes a live intervals crash on CodeGen/X86/sibcall.ll.
    The second is that it makes machinecse and licm more
    aggressive (which is a good thing) but also exposes a case
    where licm hoists a set0 and then it doesn't get resunk.

    Talking to codegen folks about both these issues, but I need
    this patch in in the meantime.

    Change how dbg_value sdnodes are converted into machine instructions. Their placement should be determined by the relative order of incoming llvm instructions. The scheduler will now use the SDNode ordering information to determine where to insert them. A dbg_value instruction is inserted after the instruction with the last highest source order and before the instruction with the next highest source order. It will optimize the placement by inserting right after the instruction that produces the value if they have consecutive order numbers.

    Here is a theoretical example that illustrates why the placement is important.

    tmp1 =
    store tmp1 -> x
    ...
    tmp2 = add ...
    ...
    call
    ...
    store tmp2 -> x

    Now mem2reg comes along:

    tmp1 =
    dbg_value (tmp1 -> x)
    ...
    tmp2 = add ...
    ...
    call
    ...
    dbg_value (tmp2 -> x)

    When the debugger examine the value of x after the add instruction but before the call, it should have the value of tmp1.

    Furthermore, for dbg_value's that reference constants, they should not be emitted at the beginning of the block (since they do not have "producers").

    This patch also cleans up how SDISel manages DbgValue nodes. It allow a SDNode to be referenced by multiple SDDbgValue nodes. When a SDNode is deleted, it uses the information to find the SDDbgValues and invalidate them. They are not deleted until the corresponding SelectionDAG is destroyed.

    Disable folding loads into tail call in 32-bit PIC mode. It can introduce illegal code like this:

            addl    $12, %esp
            popl    %esi
            popl    %edi
            popl    %ebx
            popl    %ebp
            jmpl    *__Block_deallocator-L1$pb(%esi)  # TAILCALL

    The problem is the global base register is assigned GR32 register class. TCRETURNmi needs the registers making up the address mode to have the GR32_TC register class.

    The *proper* fix is for X86DAGToDAGISel::getGlobalBaseReg() to return a copy from the global base register of the machine function rather than returning the register itself. But that has the potential of causing it to be coalesced to a more restrictive register class: GR32_TC. It can introduce additional copies and spills. For something as important the PIC base, it's not worth it especially since this is not an issue on 64-bit.

    Fix memory leak in liveintervals: the destructor for VNInfos must be called,
    otherwise the SmallVector it contains doesn't free its memory.
    In most cases LiveIntervalAnalysis could get away by not calling the destructor,
    because VNInfos are bumpptr-allocated, and smallvectors usually don't grow.
    However when the SmallVector does grow it always leaks.

    This is the valgrind shown leak from the original testcase:

    for all the back-and-forths have a look at
    CallSite.h's log.

Date:   Wed Mar 24 00:47:47 2010 +0000

    Switch SDTUnaryArithWithFlags to being modeled as a two-result
    ISD node.  The only change in the generated isel code are comments
    like:

    <                 // Src: (X86dec_flag:i16 GR16:i16:$src)
    ---
    >                 // Src: (X86dec_flag:i16:i32 GR16:i16:$src)

    because now it knows that X86dec_flag returns both an i16 (for the result)
    and an i32 (for EFLAGS) in this case.  Wewt.

    Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain crossings.

    This is work in progress. So far, SSE execution domain tables are added to
    X86InstrInfo, and a skeleton pass is enabled with -sse-domain-fix.

    Fix VLDMQ and VSTMQ instructions to use the correct encoding and address modes.
    These instructions are only needed for codegen, so I've removed all the
    explicit encoding bits for now; they should be set in the same way as the for
    VLDMD and VSTMD whenever we add encodings for VFP.  The use of addrmode5
    requires that the instructions be custom-selected so that the number of
    registers can be set in the AM5Opc value.

    Fix a very bad typo.  Since the register number was off by one, the ARM
    load/store optimizer would incorrectly think that registers D26 and D28
    were consecutive and would generate a VLDM instruction to load them.
    The assembler was not convinced.

    Clear the SCEVExpander's insertion point after making deletions,
    so that the SCEVExpander doesn't retain a dangling pointer as its
    insert position. The dangling pointer in this case wasn't ever used
    to insert new instructions, but it was causing trouble with
    SCEVExpander's code for automatically advancing its insert position
    past debug intrinsics.

    This fixes use-after-free errors that valgrind noticed in
    test/Transforms/IndVarSimplify/2007-06-06-DeleteDanglesPtr.ll and
    test/Transforms/IndVarSimplify/exit_value_tests.ll.

    Fixed the encoding problems of the crc32 instructions. All had the Operand size
    override prefix and only the r/m16 forms should have had that.  Also for variant
    one, the AT&T syntax, added suffixes to all forms.  Also added the missing
    64-bit form for 'CRC32 r64, r/m8'.  Plus added test cases for all forms and
    tweaked one test case to add the needed suffixes.

    Stop trying to merge identical jump tables.  This had been inadvertently
    disabled for several months (since svn r88806) and no one noticed.  My fix
    for pr6543 yesterday reenabled it, but broke the ARM port's code for using
    TBB/TBH.  Rather than adding a target hook to disable merging for Thumb2 only,
    I'm just taking this out.  It is not common to have identical jump tables,
    the code we used to merge them was O(N^2), and it only helps code size, not
    performance.

    MC/Mach-O/x86_64: Add relocation support.
     - This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information.
     - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily).
     - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :)

    Set numThreads to 1 by default when Python is older than 2.5.2.

    Python 2.4 always hits this bug: http://bugs.python.org/issue1731717
    when running check-lit on multi-core systems.
    Setting numThreads to 1 makes it slower, but at least the results reported are
    correct.

    Recommit r80858 again (which has been backed out in r80871).

    This time I did a self-hosted bootstrap on Linux x86-64,
    with no problems. Let's see how darwin 64-bit self-hosting
    goes. At the first sign of failure I'll back this out.

    Maybe the valgrind bots give me a hint of what may be wrong
    (it at all).

    Bugpoint's default memory limit (100MB) was too low for valgrind, so
    this patch raises the default to 800MB when valgrind's active.  800
    was chosen semi-arbitrarily.

    Now that tblgen can handle matching implicit defs of instructions
    to input patterns, we can fix X86ISD::CMP and X86ISD::BT as taking
    two inputs (which have to be the same type) and *returning an i32*.
    This is how the SDNodes get made in the graph, but we weren't able
    to model it this way due to deficiencies in the pattern language.

    Now we can change things like this:

     def UCOM_FpIr80: FpI_<(outs), (ins RFP80:$lhs, RFP80:$rhs), CompareFP,
    -                  [(X86cmp RFP80:$lhs, RFP80:$rhs),
    -                   (implicit EFLAGS)]>; // CC = ST(0) cmp ST(i)
    +                  [(set EFLAGS, (X86cmp RFP80:$lhs, RFP80:$rhs))]>;

    and fix terrible crimes like this:

    -def : Pat<(parallel (X86cmp GR8:$src1, 0), (implicit EFLAGS)),
    +def : Pat<(X86cmp GR8:$src1, 0),
               (TEST8rr GR8:$src1, GR8:$src1)>;

    This relies on matching the result of TEST8rr (which is EFLAGS, which is
    an implicit def) to the result of X86cmp, an i32.

    infer results of a pattern from implicit defs.  This allows you to do something
    like this:

     def : Pat<(add ...),
               (FOOINST)>;

    When fooinst only has a single implicit def (e.g. to R1).  This will be handled
    as if written as (set R1, (FOOINST ...))

    Work around a valgrind oddity where it doesn't pass the full path of a
    script to the #! command by using bash instead of /bin/sh.  Bash
    searches $PATH for its script argument, but dash, which /bin/sh
    resolves to on some systems, does not.
    https://bugs.kde.org/show_bug.cgi?id=231257 tracks the valgrind
    problem.

    Make this test more lenient; with SmallVector now using actually
    aligned storage, the capacity may be more than what is explicitly
    requested.

    Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() to
    always create a new jump table.  The intention was to avoid merging jump
    tables in SelectionDAGBuilder, and to wait for the branch folding pass to
    merge tables.  Unfortunately, the same getJumpTableIndex() method is also
    used to merge tables in branch folding, so as a result of this change
    branch tables are never merged.  Worse, the branch folding code is expecting
    getJumpTableIndex to always return the index of an existing table, but with
    this change, it never does so.  In at least some cases, e.g., pr6543, this
    creates references to non-existent tables.

    I've fixed the problem by adding a new createJumpTableIndex function, which
    will always create a new table, and I've changed getJumpTableIndex to only
    look at existing tables.

    Add the ability to "intern" FoldingSetNodeID data into a
    BumpPtrAllocator-allocated region to allow it to be stored in a more
    compact form and to avoid the need for a non-trivial destructor call.

    Use this new mechanism in ScalarEvolution instead of
    FastFoldingSetNode to avoid leaking memory in the case where a
    FoldingSetNodeID uses heap storage, and to reduce overall memory
    usage.

    Avoid a problem in libc_freeres() seen on a linux-i686 buildbot when running
    under valgrind:

    ==19577== Invalid free() / delete / delete[]
    ==19577==    at 0x4C9C866: free (vg_replace_malloc.c:325)
    ==19577==    by 0x5121104: ??? (in /lib/libc-2.10.2.so)
    ==19577==    by 0x4C97412: _vgnU_freeres (vg_preloaded.c:62)
    ==19577==    by 0x5041486: __run_exit_handlers (exit.c:93)
    ==19577==    by 0x50414FE: exit (exit.c:100)
    ==19577==    by 0x5028B5C: (below main) (libc-start.c:254)
    ==19577==  Address 0xffffffff is not stack'd, malloc'd or (recently) free'd
    ==19577==

    Apparently this happens under certain versions of glibc, so valgrind provides
    the --run-libc-freeres=no option to avoid calling freeres().  This may increase
    the number of "still reachable" blocks valgrind reports, but we don't care
    about those, while this error breaks the buildbots.

    There are upstream bugs about this at
    http://sourceware.org/bugzilla/show_bug.cgi?id=10610 and
    http://bugs.kde.org/show_bug.cgi?id=167483, but they don't look likely to be

    matches that of Firstcond[0] and E means otherwise.  The Firstcond[0] is also

    on this arrangement.  This is similar to what's described in A2.5.2 ITSTATE.

    Change SCEVNAryExpr's operand array from a SmallVector to a plain
    pointer and length, and allocate the arrays in ScalarEvolution's
    BumpPtrAllocator, so that they get released when their owning
    SCEV gets released. SCEVs are immutable, so they don't need to worry
    about operand array resizing. This fixes a memory leak reported
    in PR6637.

commit 78500c2059e8425a27fdfc8992e8d7f10b7dd140
Author: Johnny Chen <johnny.chen@apple.com>
Date:   Wed Mar 17 17:52:21 2010 +0000

    Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm
    instructions to help disassembly.

    We also changed the output of the addressing modes to omit the '+' from the
    assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

    And modified test cases to not expect '+' in +reg or #+num.  For example,

    ; CHECK:       ldr.w	r9, [r7, #28]

    Fix EmitSectionOffset incorrect argument. DwarfDebug is emitting debug info so isEH is always false. This was hiding until now from compilers because of default arguments. This was hiding from dwarf debug info users because for most of the platform isAbsoluteEHSectionOffsets() is same as isAbsoluteDebugSectionOffsets(). But Chris found it while updating dwarf printer to use MC*.

    Fix a false-positive memory leak in code using RemoveFileOnSignal().  Because
    libstdc++'s std::string class points to the interior of an allocation, valgrind
    reports strings still alive at program termination as possible leaks.  I didn't
    use a ManagedStatic for this because System can't depend on Support.

    Disambiguate the *_UPD  and * variants by specifying the writeback flag as 1.
    This is for the disassembly work.

    There are cases where this is not possible, for example, A8.6.53 LDM Encoding T1.
    In such case, we'll use an adhoc approach to deduce the Opcode programmatically.

commit 5fe73e8bcefe45fb8a4fbaf37504538e3c212acc
Author: Johnny Chen <johnny.chen@apple.com>
Date:   Tue Mar 16 16:36:54 2010 +0000

    Initial ARM/Thumb disassembler check-in.  It consists of a tablgen backend
    (RISCDisassemblerEmitter) which emits the decoder functions for ARM and Thumb,
    and the disassembler core which invokes the decoder function and builds up the
    MCInst based on the decoded Opcode.

    Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm
    instructions to help disassembly.

    We also changed the output of the addressing modes to omit the '+' from the
    assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

    And modified test cases to not expect '+' in +reg or #+num.  For example,

    ; CHECK:       ldr.w	r9, [r7, #28]

    Stop using the old pre-UAL syntax for LDM/STM instruction suffixes.
    This does not move entirely to UAL syntax, since the default "increment after"
    suffix is empty but we still use "IA" for that.

    I have added some doxygen to OptionalOperandTraits,

    Fix the third (and last known) case of code update problems due
    to LLVM IR changes with addr label weirdness.  In the testcase, we
    generate references to the two bb's when codegen'ing the first
    function:

    _test1:                                 ## @test1
    	leaq	Ltmp0(%rip), %rax
    ..
    	leaq	Ltmp1(%rip), %rax

    Then continue to codegen the second function where the blocks
    get merged.  We're now smart enough to emit both labels, producing
    this code:

    _test_fun:                              ## @test_fun
    ## BB#0:                                ## %entry
    Ltmp1:                                  ## Block address taken
    Ltmp0:
    ## BB#1:                                ## %ret
    	movl	$-1, %eax
    	ret

    Rejoice.

    MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.
     - Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
     - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

    Place the LSDA into the TEXT section for x86 Darwin. If the global it's pointing
    to is local to the translation unit, we need to place fill the value of that
    symbol into the non-lazy pointer.

    This should conclude all Darwin changes for placing the LSDA into the TEXT
    section. There is some cleanup to do. I.e., there's no longer a special need for
    target-specific code here. But that can come later.

    fix a memory leak yjasskin pointed out: MCSymbol is bump pointer
    allocated and thus not freed.  This is cool except that it contains
    and std::string so the string data didn't get freed.  In any case
    there is no reason to redundantly store the string data in the
    MCSymbol anyway, just make the MCSymbol ref the string data in the
    MCContext StringMap.

commit d1bcd4082aea88582d15a0e2771bb7d19a7dd5cf
Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Mar 15 06:00:16 2010 +0000

    Completely rewrite tblgen's type inference mechanism,
    changing the primary datastructure from being a
    "std::vector<unsigned char>" to being a new TypeSet class
    that actually has (gasp) invariants!

    This changes more things than I remember, but one major
    innovation here is that it enforces that named input
    values agree in type with their output values.

    This also eliminates code that transparently assumes (in
    some cases) that SDNodeXForm input/output types are the
    same, because this is wrong in many case.

    This also eliminates a bug which caused a lot of ambiguous
    patterns to go undetected, where a register class would
    sometimes pick the first possible type, causing an
    ambiguous pattern to get arbitrary results.

    With all the recent target changes, this causes no
    functionality change!

    change EH related stuff (other than EH_LABEL) to use MCSymbol
    instead of label ID's.  This cleans up and regularizes a bunch
    of code and makes way for future progress.

    Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
    is largely copy and paste from DwarfException/MachineModuleInfo
    and other places.  This is very sad and disturbing. :(

    One major change here is that TidyLandingPads moved from being
    called in DwarfException::BeginFunction to being called in
    DwarfException::EndFunction.  There should not be any
    functionality change from doing this, but I'm not an EH expert.

    rearrange MCContext ownership.  Before LLVMTargetMachine created it
    and passing off ownership to AsmPrinter.  Now MachineModuleInfo
    creates it and owns it by value.  This allows us to use MCSymbols
    more consistently throughout the rest of the code generator, and
    simplifies a bit of code.  This also allows MachineFunction to
    keep an MCContext reference handy, and cleans up the TargetRegistry
    interfaces for AsmPrinters.

    Change ARM ld/st multiple instructions to have variant instructions for
    writebacks to the address register.  This gets rid of the hack that the
    first register on the list was the magic writeback register operand.  There
    was an implicit constraint that if that operand was not reg0 it had to match
    the base register operand.  The post-RA scheduler's antidependency breaker
    did not understand that constraint and sometimes changed one without the
    other.  This also fixes Radar 7495976 and should help the verifier work
    better for ARM code.

    There are now new ld/st instructions explicit writeback operands and explicit
    constraints that tie those registers together.

    MC/Mach-O: Implement initial support for relaxation.
     - The implementation is currently very brain dead and inefficient, but I have a
       clear plan on how to fix it.

     - The good news is, it works and correctly assembles 403.gcc (when built with
       Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
       the resulting binary is exactly equivalent to that when built with the system
       assembler. So it probably works! :)

    The same situation that effected ARM effects PPC with regards to placing the
    LSDA into the TEXT section. We need to generate non-lazy pointers to it on
    Mach-O. However, the object the NLP points to may be local to the translation
    unit. If so, then the NLP needs to have the value of that object specified
    instead of "0", which the linker interprets as "external".

    The check for coalescing a virtual register to a physical register, e.g.
    cl = EXTRACT_SUBREG reg1024, 1, is overly conservative. It should check
    for overlaps of vr's live interval with the super registers of the
    physical register (ECX in this case) and let JoinIntervals() handle checking
    the coalescing feasibility against the physical register (cl in this case).

    Make clang bootstrap happier on OSX 10.5 by reducing the number of headers
    included when using global symbols to ask the linker for the addresses of
    various functions.  One of the symbols was actually getting declared by a
    header included in DynamicLibrary.cpp, which conflicted with the "extern void*"
    declaration in SearchForAddressOfSpecialSymbol().

    When outputing a non-lazy pointer for a stub, we may need to fill in the value
    for the NLP because the object it's pointing to may be internal to the file.

    This seems counter-intuitive, but bear with me. When we place the LSDA into the
    TEXT section, the type info pointers need to be indirect and pc-rel. We
    accomplish this by using NLPs. However, sometimes the types are local to the
    file. GCC gets around this by not using a NLP in this case, but a "regular"
    indirection like this:

    GCC_except_tbl:
      .long Lfoo-.

    __ZTIA:  @ This is local
      ...

    Lfoo:
      .long __ZTIA

    LLVM prefers NLPs on Darwin. In fact, it's more optimal for load performance to
    use them.

    Add a couple more heuristics to neuter machine cse some more.

    1. Be careful with cse "cheap" expressions. e.g. constant materialization. Only cse them when the common expression is local or in a direct predecessor. We don't want cse of cheap instruction causing other expressions to be spilled.
    2. Watch out for the case where the expression doesn't itself uses a virtual register. e.g. lea of frame object. If the common expression itself is used by copies (common for passing addresses to function calls), don't perform the cse. Since these expressions do not use a register, it creates a live range but doesn't close any, we want to be very careful with increasing register pressure.

    Note these are heuristics so machine cse doesn't make register allocator unhappy. Once we have proper live range splitting and re-materialization support in place, these should be evaluated again.

    Now machine cse is almost always a win on llvm nightly tests on x86 and x86_64.

    Try to keep the cached inliner costs around for a bit longer for big functions.

    The Caller cost info would be reset everytime a callee was inlined. If the
    caller has lots of calls and there is some mutual recursion going on, the
    caller cost info could be calculated many times.

    This patch reduces inliner runtime from 240s to 0.5s for a function with 20000
    small function calls.

    This is a more conservative version of r98089 that doesn't break the clang

    Try to keep the cached inliner costs around for a bit longer for big functions.

    The Caller cost info would be reset everytime a callee was inlined. If the
    caller has lots of calls and there is some mutual recursion going on, the
    caller cost info could be calculated many times.

    This patch reduces inliner runtime from 240s to 0.5s for a function with 20000
    small function calls.

    Change the Value argument to eliminateFrameIndex to a type-tagged value. This
    is preparatory to having PEI's scavenged frame index value reuse logic
    properly distinguish types of frame values (e.g., whether the value is
    stack-pointer relative or frame-pointer relative).

    No functionality change.

    The ARM EH experiment worked!

    Place the LSDA into the TEXT section for ARM platforms. This involves making the
    encoding indirect, pcrel, and sdata4 instead of an absolute pointer. The
    references to the type infos are then non-lazy pointers. Revision 98019 changed
    the encoding of non-lazy pointers to add the symbol to the non-lazy pointer
    definition if it's a local symbol (otherwise, it's external and set to '0' so
    that the loader can adjust it to the real value). This paved the way for this
    change to work on ARM.

    Disable physical register coalescing when the number of live ranges for the
    physreg becomes ridiculously high.

    std::upper_bound may be log(N), but for sufficiently large live intervals, it
    becomes log(N)*cachemiss = a long long time.

    This patch improves coalescer time by 4500x for a function with 20000
    function calls. The generated code is different, but not significantly worse -
    the allocator hints are almost as good as physreg coalescing anyway.

    simplify EmitSectionOffset to always use .set if it is
    available, the only thing this affects is that we produce
    .set in one case we didn't before, which shouldn't harm
    anything.  Make EmitSectionOffset call EmitDifference
    instead of duplicating it.

    because the instruction being duplicated had more operands that expected.

    fix a bunch of partially ambiguous patterns on ARM.  As an
    example, this:

    (set DPR:$dst, (fsub (fneg (fmul DPR:$a, DPR:$b)), DPR:$dstin))

    is ambiguous because DPR contains both f64 and v2f32.  tblgen
    currently accidentally picks f64 because it's first in the
    regclass.

    Add a missing interface to be able to call findNearestCommonDominator
    for a PostDominanceTree. The function itself is already implemented in
    DominatorTreeBase. The interface however was only added to the
    DominatorTree class, but not the PostDominatorClass.

    teach tblgen to be more aggressive when factoring CheckType nodes.
    Now it will factor things like this:

    CheckType i32
      ...
    CheckOpcode ISD::AND
      CheckType i64
      ...

    into:

    SwitchType:
      i32: ...
      i64:
        CheckOpcode ISD::AND
        ...

    This shrinks hte table by a few bytes, nothing spectacular.
