    When testing whether a given SCEV depends on a temporary symbolic
    name, test whether the SCEV itself is that temporary symbolic name,
    in addition to checking whether the symbolic name appears as a
    possibly-indirect operand.

commit 657373b3503c19e66e2dd7a396f14b8986883f81

    Check in the first big step of rewriting DAGISelEmitter to
    produce a table based matcher instead of gobs of C++ Code.

    Though it's not done yet, the shrinkage seems promising,
    the table for the X86 ISel is 75K and still has a lot of
    optimization to come (compare to the ~1.5M of .o generated
    the old way, much of which will go away).

    The code is currently disabled by default (the #if 0 in
    DAGISelEmitter.cpp).  When enabled it generates a dead
    SelectCode2 function in the DAGISel Header which will
    eventually replace SelectCode.

    There is still a lot of stuff left to do, which are
    documented with a trail of FIXMEs.

    remove the DisablePatternForFastISel predicate, which is a check
    that predated -fast-isel which attempted to speed up the dag pattern
    matchers at -O0.  Since fast-isel is around, this is basically
    obsolete and removing it shrinks the generated dag isels.

    When complicated expressions are broken down into subexpressions
    with multiplication by constants distributed through, occasionally
    those subexpressions can include both x and -x. For now, if this
    condition is discovered within LSR, just prune such cases away,
    as they won't be profitable. This fixes a "zero allocated in a
    base register" assertion failure.

    In rememberInstruction, if the value being remembered is the

    and add a doxygen comment.

    Cache the phi entry to avoid doing tons of

    Fix PR6283.

    When coalescing with a physreg, remember to add imp-def and imp-kill when
    dealing with sub-registers.

    Also fix a related bug in VirtRegRewriter where substitutePhysReg may
    reallocate the operand list on an instruction and invalidate the reg_iterator.
    This can happen when a register is mentioned twice on the same instruction.

    Teach MachineFrameInfo to track maximum alignment while stack objects are being
    created. This ensures it's updated at all time. It means targets which perform
    dynamic stack alignment would know whether it is required and whether frame
    pointer register cannot be made available register allocation.
    This is a fix for rdar://7625239. Sorry, I can't create a reasonably sized test
    case.

    Enable the inlinehint attribute in the Inliner.

    Functions explicitly marked inline will get an inlining threshold slightly
    more aggressive than the default for -O3. This means than -O3 builds are
    mostly unaffected while -Os builds will be a bit bigger and faster.

    The difference depends entirely on how many 'inline's are sprinkled on the
    source.

    In the CINT2006 suite, only these tests are significantly affected under -Os:

                   Size   Time
    471.omnetpp   +1.63% -1.85%
    473.astar     +4.01% -6.02%
    483.xalancbmk +4.60%  0.00%

    Note that 483.xalancbmk runs too quickly to give useful timing results.

    Reworked the Intel disassembler to support instructions
    whose opcodes extend into the ModR/M field using the
    Form field of the instruction rather than by special
    casing each instruction.  Commented out the special
    casing of VMCALL, which is the first instruction to use
    this special form.  While I was in the neighborhood,
    added a few comments for people modifying the Intel

    When save/restoring CR at prolog/epilog, in a large
    stack frame, the prolog/epilog code was using the same
    register for the copy of CR and the address of the save slot.  Oops.
    This is fixed here for Darwin, sort of, by reserving R2 for this case.
    A better way would be to do the store before the decrement of SP,
    which is safe on Darwin due to the red zone.

    SVR4 probably has the same problem, but I don't know how to fix it;
    there is no red zone and R2 is already used for something else.
    I'm going to leave it to someone interested in that target.

    Better still would be to rewrite the CR-saving code completely;
    spilling each CR subregister individually is horrible code.

       doing so is quite dubious at best anyway.

       merge two globals in different address spaces.

    Add a new pass on machine instructions to optimize away PHI cycles that
    reduce down to a single value.  InstCombine already does this transformation
    but DAG legalization may introduce new opportunities.  This has turned out to
    be important for ARM where 64-bit values are split up during type legalization:
    InstCombine is not able to remove the PHI cycles on the 64-bit values but
    the separate 32-bit values can be optimized.  I measured the compile time
    impact of this (running llc on 176.gcc) and it was not significant.

    Add and commonize encoder support for all immediates.
    Stub out some dummy fixups to make things work.

    We can now emit fixups like this:
    	subl	$20, %esp               ## encoding: [0x83,0xec,A]
                                            ##   fixup A - offset: 2, value: 20, kind: fixup_1byte_imm

    Emitting $20 as a single-byte fixup to be later resolved
    by the assembler is ridiculous of course (vs just emitting
    the byte) but this is a failure of the matcher, which
    should be producing an imm of 20, not an MCExpr of 20.

    Rename ValueRequiresCast to ShouldOptimizeCast, to better reflect
    what it does.  Enhance it to return false to optimizing vector
    sign extensions from vector comparisions, which is the idiom used
    to get a splatted vector for a vector comparison.

    Doing this breaks vector-casts.ll, add some compensating
    transformations to handle the important case they cover without
    depending on this canonicalization.

    This fixes rdar://7434900 a serious pessimization of vector compares.

    Make it possible to create multiple JIT instances at the same time, by removing
    the global TheJIT and TheJITResolver variables.  Lazy compilation is supported
    by a global map from a stub address to the JITResolver that knows how to
    compile it.

    The previous fix of widening divides that trap was too fragile as it depends on custom
    lowering and requires that certain types exist in ValueTypes.h.  Modified widening to
    check if an op can trap and if so, the widening algorithm will apply only the op on
    the defined elements.  It is safer to do this in widening because the optimizer can't
    guarantee removing unused ops in some cases.

    Delete dead PHI machine instructions.  These can be created due to type
    legalization even when the IR-level optimizer has removed dead phis, such
    as when the high half of an i64 value is unused on a 32-bit target.
    I had to adjust a few test cases that had dead phis.
    This is a partial fix for Radar 7627077.

Author: Garrison Venn <gvenn.cfe.dev@gmail.com>
Date:   Tue Feb 9 23:22:43 2010 +0000

    Adds a JIT based exception handling example to the examples directory.
    Both zero cost example domain specific, and C++ foreign exception handling are
    shown. The example's documentation fully explains how to run the example.

    Notes:

    1)   The code uses an extremely simple type info model.
    2)   Only a single landing pad is used per unwind edge
         (one call to llvm.eh.selector)
    3)   llvm.eh.selector support for filter arguments is not given.
    4)   llvm.eh.typeid.for is not used.
    5)   Forced unwind behavior is not supported.
    6)   Very little if any error handling is given.
    7)   __attribute__((__aligned__)) is used.
    8)   The code uses parts from the llvm compiler-rt project and
         the llvm Kaleidoscope example.
    9)   The code has not been ported or tested on WINDOWS.
    10)  The code was not tested with a cmake build.
    11)  The code was tested for a debug build on 32bit X86 CentOS LINUX,
         and both a debug and release build on OS X 10.6.2 (64bit).

    things here let me know, doesn't seem to be any

    Per PR 6219, factored AsmWriterInst and AsmWriterOperand
    out of the AsmWriterEmitter.  This patch does the physical
    code movement, but leaves the implementation unchanged. I'll

    separate patch.

    in X86-32 mode.  This is still required in x86-64 mode to avoid
    forming [disp+rip] encoding.  Rewrite the SIB byte decision logic
    to be actually understandable.

    Radar 7417921

    tMOVCCi pattern only valid for low registers, as the Thumb1 mov immediate to
    register instruction only works with low registers. Allowing high registers
    for the instruction resulted in the assembler choosing the wide (32-bit)
    encoding for the mov, but LLVM though the instruction was only 16 bits wide,
    so offset calculations for constant pools became incorrect, leading to
    out of range constant pool entries.

    Fixed a bug in the PBQP allocator's findCoalesces method.

    Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with.

    Add a new pass to do llvm.objsize lowering using SCEV.
    Initial skeleton and SCEVUnknown lowering implemented,
    the rest should come relatively quickly.  Move testcase

    Move pass to right before SimplifyLibCalls - which is
    moved down a bit so we can take advantage of a few opts.

    Give DwarfPrinter a protected (but not virtual) destructor.  Cppcheck
    warns about this base class not having a virtual destructor, but since
    this class has no virtual methods and neither it or the types derived
    from it has a destructor, a protected trivial destructor will do (and
    shuts cppcheck up) the trick without the cost of introducing a vtable.

    - o32 cc must pass all arguments in A0...A3 and stack regardless
    if its type (but respect the alignment).
    - Store all variable arguments back to the caller stack.

    Run codegen dce pass for all targets at all optimization levels. Previously it's
    only run for x86 with fastisel. I've found it being very effective in
    eliminating some obvious dead code as result of formal parameter lowering
    especially when tail call optimization eliminated the need for some of the loads
    from fixed frame objects. It also shrinks a number of the tests. A couple of
    tests no longer make sense and are now eliminated.

    Reintroduce the InlineHint function attribute.

    This time it's for real! I am going to hook this up in the frontends as well.

    The inliner has some experimental heuristics for dealing with the inline hint.
    When given a -respect-inlinehint option, functions marked with the inline
    keyword are given a threshold just above the default for -O3.

    We need some experiments to determine if that is the right thing to do.

    Teach SimplifyCFG about magic pointer constants.

    Weird code sometimes uses pointer constants other than null. This patch
    teaches SimplifyCFG to build switch instructions in those cases.

    Code like this:

    void f(const char *x) {
      if (!x)
        puts("null");
      else if ((uintptr_t)x == 1)
        puts("one");
      else if (x == (char*)2 || x == (char*)3)
        puts("two");
      else if ((intptr_t)x == 4)
        puts("four");
      else
        puts(x);
    }

    Now becomes a switch:

    define void @f(i8* %x) nounwind ssp {
    entry:
      %magicptr23 = ptrtoint i8* %x to i64            ; <i64> [#uses=1]
      switch i64 %magicptr23, label %if.else16 [
        i64 0, label %if.then
        i64 1, label %if.then2
        i64 2, label %if.then9
        i64 3, label %if.then9
        i64 4, label %if.then14
      ]

    Note that LLVM's own DenseMap uses magic pointers.

    Move --march, --mcpu, and --mattr from JIT/TargetSelect.cpp to lli.cpp.
    llc.cpp also defined these flags, meaning that when I linked all of LLVM's
    libraries into a single shared library, llc crashed on startup with duplicate
    flag definitions.  This patch passes them through the EngineBuilder into
    JIT::selectTarget().

    When the scheduler unfold a load folding instruction it move some of the predecessors to the unfolded load. It decides what gets moved to the load by checking whether the new load is using the predecessor as an operand. The check neglects the cases whether the predecessor is a flagged scheduling unit.

    An empty global constant (one of size 0) may have a section immediately
    following it. However, the EmitGlobalConstant method wasn't emitting a body for
    the constant. The assembler doesn't like that. Before, we were generating this:

      .zerofill __DATA, __common, __cmd, 1, 3

    This fix puts us back to that semantic.

    Do not reassociate expressions with i1 type.  SimplifyCFG converts some
    short-circuited conditions to AND/OR expressions, and those expressions
    are often converted back to a short-circuited form in code gen.  The
    original source order may have been optimized to take advantage of the
    expected values, and if we reassociate them, we change the order and
    subvert that optimization.  Radar 7497329.

    Indirect tail call has to go through a call preserved register since it's after callee register pops. X86 isel lowering is using EAX / R11 and it was somehow adding that to function live out. That prevented the real function return register from being added to the function live out list and bad things happen.
    This fixes 483.xalancbmk (with tail call opt).

Author: Kevin Enderby <enderby@apple.com>
Date:   Wed Feb 3 21:04:42 2010 +0000

    Added support for X86 instruction prefixes so llvm-mc can assemble them.  The
    Lock prefix, Repeat string operation prefixes and the Segment override prefixes.
    Also added versions of the move string and store string instructions without the
    repeat prefixes to X86InstrInfo.td. And finally marked the rep versions of
    move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is
    happy building the disassembler files.

    r94686 changed all ModuleProvider parameters to Modules, which made the
    1-argument ExecutionEngine::create(Module*) ambiguous with the signature that
    used to be ExecutionEngine::create(ModuleProvider*, defaulted_params).  Fixed
    by removing the 1-argument create().  Fixes PR6221.

commit 66b7149074808f51fd6365b509028ff862a05108
Author: Bob Wilson <bob.wilson@apple.com>
Date:   Wed Feb 3 17:23:56 2010 +0000

    Adjust the heuristics used to decide when SROA is likely to be profitable.
    The SRThreshold value makes perfect sense for checking if an entire aggregate
    should be promoted to a scalar integer, but it is not so good for splitting
    an aggregate into its separate elements.  A struct may contain a large embedded
    array along with some scalar fields that would benefit from being split apart
    by SROA.  Even if the total aggregate size is large, it may still be good to
    perform SROA.  Thus, the most important piece of this patch is simply moving
    the aggregate size comparison vs. SRThreshold so that it guards only the
    aggregate promotion.

    We have also been checking the number of elements to decide if an aggregate
    should be split up.  The limit of "SRThreshold/4" seemed rather arbitrary,
    and I don't think it's very useful to derive this limit from SRThreshold
    anyway.  I've collected some data showing that the current default limit of
    32 (since SRThreshold defaults to 128) is a reasonable cutoff for struct
    types.  One thing suggested by the data is that distinguishing between structs
    and arrays might be useful.  There are (obviously) a lot more large arrays
    than large structs (as measured by the number of elements and not the total
    size -- a large array inside a struct still counts as a single element given
    the way we do SROA right now).  Out of 8377 arrays where we successfully
    performed SROA while compiling a large set of benchmarks, only 16 of them had
    more than 8 elements.  And, for those 16 arrays, it's not at all clear that
    SROA was actually beneficial.  So, to offset the compile time cost of
    investigating more large structs for SROA, the patch lowers the limit on array
    elements to 8.

    This fixes Apple Radar 7563690.

    ByVal frame object size should be that of the byval argument, not the size of the type which is just a pointer. This is not known to break stuff but is wrong nevertheless.

    Hook up -filetype=obj through the MachO streamer.  Here's a demo:

    $ cat t.ll
    @g = global i32 42
    $ llc t.ll -o t.o -filetype=obj
    $ nm t.o
    00000000 D _g

    There is still a ton of work left.  Instructions are not being encoded
    yet apparently.

commit c74cb6dfb1a37f36bf306ce88282c8478c40f062
Author: Kevin Enderby <enderby@apple.com>
Date:   Tue Feb 2 19:05:57 2010 +0000

    Added another version of the X86 assembler matcher test case.
    This test case is different subset of the full auto generated test case, and a
    larger subset that is in x86_32-bit.s (that set will encode correctly).  These
    instructions can pass though llvm-mc as it were a logical cat(1) and then
    reassemble to the same instruction.  It is useful as we bring up the parser and
    matcher so we don't break things that currently work.

    Changed to Chris Lattner's suggested approach, which
    merely stubs out the blocks-based disassembly functions
    if the library wasn't built with blocks, which allows a
    constant .exports file and also properly deals with
    situations in which the compiler used to build a client
    is different from the compiler used to build the library.

    Fixed a couple of optimization with EXTRACT_VECTOR_ELT that assumes the result
    type is the same as the element type of the vector.  EXTRACT_VECTOR_ELT can

    Generalize target-independent folding rules for sizeof to handle more
    cases, and implement target-independent folding rules for alignof and
    offsetof. Also, reassociate reassociative operators when it leads to
    more folding.

    Generalize ScalarEvolution's isOffsetOf to recognize offsetof on
    arrays. Rename getAllocSizeExpr to getSizeOfExpr, and getFieldOffsetExpr
    to getOffsetOfExpr, for consistency with analagous ConstantExpr routines.

    Make the target-dependent folder promote GEP array indices to
    pointer-sized integers, to make implicit casting explicit and exposed
    to subsequent folding.

    And add a bunch of testcases for this new functionality, and a bunch
    of related existing functionality.

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

    fix rdar://7590304, an infinite loop in instcombine.  In the invoke
    case, instcombine can't zap the invoke for fear of changing the CFG.
    However, we have to do something to prevent the next iteration of
    instcombine from inserting another store -> undef before the invoke
    thereby getting into infinite iteration between dead store elim and
    store insertion.

    Just zap the callee to null, which will prevent the next iteration
    from doing anything.

    FileCheck: When looking for "possible matches", only compare against the prefix
    line. Turns out edit_distance can be slow if the string we are scanning for
    happens to be quite large.

    Keep iterating over all uses when meeting a phi node in AllUsesOfValueWillTrapIfNull().

    This bug was exposed by my inliner cost changes in r94615, and caused failures
    of lencod on most architectures when building with LTO.

    This patch fixes lencod and 464.h264ref on x86-64 (and likely others).

    MC/X86: Add a nice X86 assembler matcher test case from Kevin Enderby.
     - This test case is auto generated, and has been verified to round-trip
       correctly through llvm-mc by checking the assembled .o file before and after
       piping through llvm-mc. It will be extended over time as the matcher grows
       support for more instructions.

    Modified encoding bits specification for VFP instructions.  In particular, the D
    bit (Inst{22}) and the M bit (Inst{5}) should be left unspecified.  For binary

    Preserve load alignment in instcombine transformations.  I've been unable to
    create a testcase where this matters.  The select+load transformation only
    occurs when isSafeToLoadUnconditionally is true, and in those situations,
    instcombine also changes the underlying objects to be aligned.  This seems
    like a good idea regardless, and I've verified that it doesn't pessimize
    the subsequent realignment.

    Having RHSKnownZero and RHSKnownOne be alternative names for KnownZero and KnownOne
    (via APInt &RHSKnownZero = KnownZero, etc) seems dangerous and confusing to me: it
    is easy not to notice this, and then wonder why KnownZero/RHSKnownZero changed
    underneath you when you modified RHSKnownZero/KnownZero etc.  So get rid of this.
    No intended functionality change (tested with "make check" + llvm-gcc bootstrap).

    fashion, and if they don't have an ordering set, then give it one.

commit a64c74890ef37c607b3f1742abb5b1af65342afa
Author: Dan Gohman <gohman@apple.com>
Date:   Thu Jan 28 18:08:26 2010 +0000

    Remove the folding rule
      getelementptr (i8* inttoptr (i64 1 to i8*), i32 -1)
      to
      inttoptr (i64 0 to i8*)
    from the VMCore constant folder. It didn't handle sign-extension properly
    in the case where the source integer is smaller than a pointer size. And,
    it relied on an assumption about sizeof(i8).

    The Analysis constant folder still folds these kinds of things; it has
    access to TargetData, so it can do them right.

    Add a testcase which tests that the VMCore constant folder doesn't
    miscompile this, and that the Analysis folder does fold it.

    Remove SCEVAllocSizeExpr and SCEVFieldOffsetExpr, and in their place
    use plain SCEVUnknowns with ConstantExpr::getSizeOf and
    ConstantExpr::getOffsetOf constants. This eliminates a bunch of
    special-case code.

    Also add code for pattern-matching these expressions, for clients that
    want to recognize them.

    Move ScalarEvolution's logic for expanding array and vector sizeof
    expressions into an element count times the element size, to expose
    the multiplication to subsequent folding, into the regular constant
    folder.

Date:   Wed Jan 27 20:34:15 2010 +0000

    Kill ModuleProvider and ghost linkage by inverting the relationship between
    Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
    GlobalValues now, and doesn't provide modules, it's renamed to
    "GVMaterializer". Code that used to need a ModuleProvider to materialize
    Functions can now materialize the Functions directly. Functions no longer use a
    magic linkage to record that they're materializable; they simply ask the
    GVMaterializer.

    Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
    the functions that refer to it. Instead, because Module now exposes the same
    functionality ModuleProvider used to, we store a Module* in any
    LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
    other languages still use the ModuleProvider concept.  It would probably be
    worth some time to update them to follow the C++ more closely, but I don't
    intend to do it.

    Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.

    Perform trivial tail call optimization for callees with "C" ABI. These are done
    even when -tailcallopt is not specified and it does not require changing ABI.
    First case is the most trivial one. Perform tail call optimization when both
    the caller and callee do not return values and when the callee does not take
    any input arguments.

    Eliminate target hook IsEligibleForTailCallOptimization.

    Target independent isel should always pass along the "tail call" property. Change
    target hook LowerCall's parameter "isTailCall" into a refernce. If the target
    decides it's impossible to honor the tail call request, it should set isTailCall
    to false to make target independent isel happy.

    Fix inline cost predictions with SCIENCE.

    After running a batch of measurements, it is clear that the inliner metrics
    need some adjustments:

    Own argument bonus:       20 -> 5
    Outgoing argument penalty: 0 -> 5
    Alloca bonus:             10 -> 5
    Constant instr bonus:      7 -> 5
    Dead successor bonus:     40 -> 5*(avg instrs/block)

    The new cost metrics are generaly 25 points higher than before, so we may need
    to move thresholds.

    With this change, InlineConstants::CallPenalty becomes a political correction:

    if (!isa<IntrinsicInst>(II) && !callIsSmall(CS.getCalledFunction()))
      NumInsts += InlineConstants::CallPenalty + CS.arg_size();

    The code size is accurately modelled by CS.arg_size(). CallPenalty is added
    because calls tend to take a long time, so it may not be worth it to inline a
    function with lots of calls.

    All of the political corrections are in the InlineConstants namespace:
    IndirectCallBonus, CallPenalty, LastCallToStaticBonus, ColdccPenalty,
    NoreturnPenalty.

    CountCodeReductionForAlloca().

    This patch should remove a small positive bias toward inlining functions with
    variable-index GEPs, and remove a smaller negative bias from functions with
    all-constant index GEPs.

Date:   Tue Jan 26 21:31:30 2010 +0000

    Remove dead code.

    Functions containing indirectbr are marked NeverInline by analyzeBasicBlock(),
    so there is no point in giving indirectbr special treatment in
    CountCodeReductionForConstant. It is never called.

    No functional change intended.

    Eliminate SetDirective, and replace it with HasSetDirective.
    Default HasSetDirective to true, since most targets have it.

    The targets that claim to not have it probably do, or it is
    spelled differently. These include Blackfin, Mips, Alpha, and
    PIC16.  All of these except pic16 are normal ELF targets, so
    they almost certainly have it.

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

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

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

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

    Next up, more testing.

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

    Move the dominator verification code out of special code embedded within
    the PassManager code into a regular verifyAnalysis method.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    Add a TrackingVH value handle.

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

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

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

    to
    %S0<def> = IMPLICIT_DEF %Q0<imp-use,kill>

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

    Recognize SSE min and max opportunities in even more cases.
    And fix a bug with the behavior of min/max instructions formed from
    fcmp uge comparisons.

    Also, use FiniteOnlyFPMath() for this code instead of UnsafeFPMath,
    as it is more specific.

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

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

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

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

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

    and dramatically better than that produced by gcc 4.2:

    _test_bitfield:
    	pushl	%ebx
    	call	L3
    "L00000000001$pb":
    L3:
    	popl	%ebx
    	movl	8(%esp), %eax
    	leal	0(,%eax,4), %edx
    	sarb	$7, %dl
    	movl	%eax, %ecx
    	andl	$7168, %ecx
    	andl	$-7201, %ebx
    	movzbl	%dl, %edx
    	andl	$1, %edx
    	sall	$5, %edx
    	orl	%ecx, %ebx
    	orl	%edx, %ebx
    	andl	$24, %eax
    	andl	$-58336, %ebx
    	orl	%eax, %ebx
    	orl	$32962, %ebx
    	movl	%ebx, %eax

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

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

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

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

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

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

    Consider running the following program through the JIT:

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

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

    don't use count + insert, just do insert + failure.  Also, instead of deleting from
    the middle of a vector, swap the last element in and pop_back.  Also saves 330 bytes :)

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

    Here's fun! It turns out that these filter functions can be internal. If they're
    internal, they shouldn't use the indirect pointer stuff. In the case of
    throw_rethrow_test, it was marked as 'internal' and calculated its own offset to
    its contents.

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

    The flag "--dot-cfg-only" is at the moment equivalent to the flag "--dot-cfg".
    It prints the content of all bbs, instead of printing empty bbs to make the
    CFG more readable.  Fix this.  Patch by Tobias Grosser.

    It's inefficient to have place the exception tables (which contain the LSDA)
    into the __DATA section. At launch time, dyld has to update most of the section
    to fix up the type info pointers. It's better to place it into the __TEXT
    section and use pc-rel indirect pointer encodings. Similar to the personality
    routine.

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

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

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

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

    This also unblocks other changes that Bill wants to make.

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

    Do not try and sink a load whose chain result has more than one use, when
    trying to create RMW opportunities in the x86 backend.  This can cause a
    cycle to appear in the graph, since the other uses may eventually feed into
    the TokenFactor we are sinking the load below.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    Substantially speed up combiner-aa in the following ways:

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

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

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

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

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

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

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

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

Date:   Fri Sep 11 20:46:33 2009 +0000

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

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

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

    switch HiddenGVStubs to be a DenseMap instead of a string map, mirroring FnStubs and GVStubs.

    Fix a bug I introduced in FnStubs generation, switch GVStubs to be a

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

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

    reimplement X86ATTAsmPrinter::GetGlobalAddressSymbol in terms of
    Mangler::getNameWithPrefix.  In addition to avoiding some over
    quoting, this also is more efficient because it uses smallvector
    instead of std::string thrashing.

    add a new Mangler::getNameWithPrefix API which returns the
    (uniqued if unnamed) global variable name with the prefix that
    it is supposed to get.  It doesn't do "mangling" in the sense of
    adding quotes and hacking on bad characters.

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

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

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

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

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

    Remove the "#if 0" that Noone loved. It wasn't really necessary, because the
    code within it was the same inside and out. There's still a problem of the
    TypeInfoSize should be the size of the TType format encoding (at least that's
    what GCC thinks it should be).

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

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

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

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

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

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

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

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

    Make TypeBuilder's result depend on the LLVMContext it's passed.
    TypeBuilder was using a local static variable to cache its result. This made it

    from the argument to the first call.

    Use MemoryBuffer::getBufferIdentifier() in the AsmPrinter instead

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

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

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

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

    I'll let those people who care about the performance of vector

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

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

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

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

    Fix a thinko: When lowering fneg with xor, bitcast the operands
    from floating-point to integer first, and bitcast the result
    back to floating-point. Previously, this test was passing by
    falling back to SelectionDAG lowering. The resulting code isn't
    as nice, but it's correct and CodeGen now stays on the fast path.

    Don't commit stores with addresses that have indices that are not

    Fix GlobalOpt to avoid committing a store if the address getelementptr

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

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

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

Date:   Fri Sep 4 12:08:11 2009 +0000

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

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

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

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

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

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

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

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

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

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

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

    Implement support for X86II::MO_GOT_ABSOLUTE_ADDRESS.  We get very
    different formatting from the old asmprinter, but it should be
    semantically the same.  We used to get:

    	popl	%eax
    	addl	$_GLOBAL_OFFSET_TABLE_ + [.-.Lllvm$6.$piclabel], %eax
    ...

    Now we get:

    	popl	%eax
    .Lpicbaseref6:
    	addl	$(_GLOBAL_OFFSET_TABLE_ + (.Lpicbaseref6 - .Lllvm$6.$piclabel)), %eax
    ...

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

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

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

    Preparation for Optimal Edge Profiling:
    Optimal edge profiling is only possible when blocks with no predecessors get an

    function-exiting blocks.
    This patch makes the necessary changes before actually enabling optimal edge profiling.

    Change CallGraphNode to maintain it's Function as an AssertingVH
    for sanity.  This didn't turn up any bugs.

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

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

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

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

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

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

    These fix compile-time problems in some pathlogical cases.
