    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.

    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.

    Tweak the way appendModuleInlineAsm works, so you aren't obliged
    to append a newline when using setModuleInlineAsm in case later
    someone calls appendModuleInlineAsm - make newline handling fully

    AC_PROG_LIBTOOL is not needed since we don't use libtool, we only need the
    libltdl checks for dlopen.
    Add check for AR, it used to be done by AC_PROG_LIBTOOL.
    AC_TYPE_SIGNAL is deprecated, follow autoupdate's suggestion and replace with
    void.

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

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

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

    New PBQP solver.

    * Fixed a reduction bug which occasionally led to infinite-cost (invalid)
      register allocation solutions despite the existence finite-cost solutions.

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

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

    This addresses rdar://7561161.

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

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

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

Date:   Mon Jan 25 18:26:54 2010 +0000

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

    Previously we would just silently miscompile code that used aligned

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

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

    However, I think that this directive should be safe on any ELF target.
    If so, we should hoist it up out of the X86 and SystemZ targets.

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

    add a new DwarfPrinter::EmitEncodingByte method which handles
    pretty printing encoding comments and eliminates redundancy on
    the client side.  We now get pretty dwarf like this again:

            .byte   255                                         ## @LPStart Encoding = omit

    Filled out the skeleton of the TargetAsmLexer to behave
    exactly like an MCAsmLexer.  (The difference is that the
    TargetAsmLexer knows how to handle target-specific stuff
    like registers, whereas the MCAsmLexer is fully generic.)

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

    LBB1_4:                                                     ## %land.end
                                                                ##   in Loop: Header=BB1_1 Depth=1
            notb    %al
            testb   $1, %al
            jne     LBB1_8

    and:

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

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

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

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

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

    When re-using an existing cast for a user, it's still necessary to call

    Fix a crasher trying to fold each element in a comparison between two vectors
    if one of the vectors didn't have elements (such as undef). Fixes PR 6096.

    Fix an issue in the constant folder where fcmp (<2 x %ty>, <2 x %ty>) would
    have <2 x i1> type if constant folding was successful and i1 type if it wasn't.
    This exposed a related issue in the bitcode reader.

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

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

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

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

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

Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Jan 19 05:38:33 2010 +0000

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

    Some notes:

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

    This leads to a nice diffstat:

    Cleanup handling of .zerofill on darwin:

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

    Enable code to emit dbg.declare as DEBUG_VALUE
    comments (fast isel, X86).  This doesn't seem
    to break any functionality, but will introduce
    cases where -g affects the generated code.  I'll
    be fixing that.

    my instcombine transformations to make extension elimination more
    aggressive changed the canonical form from sext(trunc(x)) to ashr(lshr(x)),

    Canonicalize -1 - x to ~x.

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

    The most significant encoding bit of GPR:$src or GPR:$dst was over-specified in
    the various MOV (register) instructions (16-bit Thumb), including tBRIND (the
    indirect branch).  Instead of '1', it should be specified as '?', because GPR
    only specifies the register class, which includes both hi-and-lo registers.

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

    This also fixes some weirdness where two MCSymbols could be created

    to a console, when --analyze is used.

    Similarly, avoid creating an empty output file when --disable-output is used.

    Print a warning when the -o option appears with either --analyze or
    --disable-output, to indicate that the option is being ignored.

    The Neon "vtst" instruction takes a suffix that is the element size alone --
    adding an "i" to the suffix, indicating that the elements are integers, is
    accepted but not part of the standard syntax.  This helps us pass a few more
    of the Neon tests from gcc.

    Retrying r91337:

    The CIE says that the LSDA point in the FDE section is an "sdata4". That's fine,
    but we need it to actually be 4-bytes in the FDE for some platforms. Allow
    individual platforms to decide for themselves.

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

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

    Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast).
    This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.
    It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    use the new form of getNameWithPrefix, not makeNameProper.
    Among other things, this would do very weird things if the

    makeNameProper would add quotes, then the mcsymbol would
    escape the quotes.

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

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

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

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

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

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

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

    Disable folding sext(trunc(x)) -> x (and other similar cast/cast cases) when the

    Reimplement getToken and SplitString as "StringRef helper functions"

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

    Implement a feature (-vector-unaligned-mem) to allow targets to
    ignore alignment requirements for SIMD memory operands.  This
    is useful on architectures like the AMD 10h that do not trap on
    unaligned references if a status bit is twiddled at startup time.

    add one more bitfield optimization, allowing clang to generate
    good code on PR4216:

    _test_bitfield:                                             ## @test_bitfield

    	movl	$4294941946, %eax
    	andq	%rdi, %rax
    	ret

    instead of:

    _test_bitfield:
            movl    $4294941696, %ecx
            movl    %edi, %eax

Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Jan 11 04:05:13 2010 +0000

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

    clang now compiles the code in PR4216 into:

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

    instead of:

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

    which is still not great, but is progress.

    Remove the dead TD argument to CanEvaluateZExtd, and add a
    new BitsToClear result which allows us to start promoting
    expressions that end with a lshr-by-constant.  This is
    conservatively correct and better than what we had before
    (see testcases) but still needs to be extended further.

    teach zext optimization how to deal with truncs that don't come from
    the zext dest type.  This allows us to handle test52/53 in cast.ll,
    and allows llvm-gcc to generate much better code for PR4216 in -m64
    mode:

    _test_bitfield:                                             ## @test_bitfield
    	orl	$32962, %edi

    now that the cost model has changed, we can always consider

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

    Fix http://llvm.org/PR5729: x86-64 tail calls were putting their targets into
    R11, and then asserting that the target was in R9.  Since R9 isn't reserved for
    the target anymore, and is used as an argument, this patch changes the
    assertion.

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

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

    Revert an earlier change to SIGN_EXTEND_INREG for vectors. The VTSDNode
    really does need to be a vector type, because
    TargetLowering::getOperationAction for SIGN_EXTEND_INREG uses that type,
    and it needs to be able to distinguish between vectors and scalars.

    Also, fix some more issues with legalization of vector casts.

    now handles vectors, and you can't insertelement into a vector.  It
    would be 'really nice' if GEP into a vector were not legal.

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

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

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

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

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

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

    Remove livein checks from machine code verifier.

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

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

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

    Also, give BitVector empty and swap functions.

    And, add some simple unittests for BitVector and SmallBitVector.

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

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

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

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

    Thanks to Duncan for pointing this possible problem out.

    generalize the previous transformation to handle indexing into
    arrays of structs and other arrays, so long as all the subsequent
    indexes are constants.  This triggers frequently for stuff like:

    @divisions = internal constant [29 x [2 x i32]] [[2 x i32] zeroinitializer, [2 x i32] [i32 0, i32 1], [2 x i32] [i32 0, i32 2], [2 x i32] [i32 0, i32 1], [2 x i32] zeroinitializer, [2 x i32] [i32 0, i32 1], [2 x i32] [i32 0, i32 1], [2 x i32] [i32 0, i32 2], [2 x i32] [i32 0, i32 2], [2 x i32] zeroinitializer, [2 x i32] zeroinitializer, [2 x i32] zeroinitializer, [2 x i32] [i32 0, i32 2], [2 x i32] [i32 0, i32 1], [2 x i32] zeroinitializer, [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 1], [2 x i32] [i32 1, i32 1], [2 x i32] [i32 1, i32 2], [2 x i32] [i32 1, i32 1], [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 2], [2 x i32] [i32 1, i32 2], [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 0], [2 x i32] [i32 1, i32 1], [2 x i32] [i32 1, i32 2], [2 x i32] [i32 1, i32 2]], align 32 ; <[29 x [2 x i32]]*> [#uses=50]

    	  %623 = getelementptr inbounds [29 x [2 x i32]]* @divisions, i64 0, i64 %619, i64 0 ; <i32*> [#uses=1]
    	   %684 = icmp eq i32 %683, 999

    teach instcombine to optimize idioms like A[i]&42 == 0.  This
    occurs in 403.gcc in mode_mask_array, in safe-ctype.c (which
    is copied in multiple apps) in _sch_istable, etc.

    git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92427 91177308-0d34-0410-b5e6-96231b3b80d8

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

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

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

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

    400.perlbmk has stuff like this:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    go 64-bit machines :)

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

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

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

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

    @must_be_connected_without = internal constant [8 x i8*] [i8* getelementptr inbounds ([3 x i8]* @.str64320, i64 0, i64 0), i8* getelementptr inbounds ([3 x i8]* @.str27283, i64 0, i64 0), i8* getelementptr inbounds ([4 x i8]* @.str71327, i64 0, i64 0), i8* getelementptr inbounds ([4 x i8]* @.str72328, i64 0, i64 0), i8* getelementptr inbounds ([3 x i8]* @.str18274, i64 0, i64 0), i8* getelementptr inbounds ([6 x i8]* @.str11267, i64 0, i64 0), i8* getelementptr inbounds ([3 x i8]* @.str32288, i64 0, i64 0), i8* null], align 32 ; <[8 x i8*]*> [#uses=2]

    remove the instcombine transformations that are inserting nasty

    for details.

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

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

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

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

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

    into:

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

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

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

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

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

    define i32 @test12(i32 %X) {
      %factor = mul i32 %X, -3                        ; <i32> [#uses=1]
      %Z = add i32 %factor, 6                         ; <i32> [#uses=1]
      ret i32 %Z
    }

    instead of:

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

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

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

    do not bother reuniquing mdnodes whose operands drop to null.  Doing
    so can be a huge performance issue when tearing down modules and mdnodes
    are not guaranteed to be unique anyway.  This speeds up:
    $ time ~/llvm/Release/bin/clang gcc.c -w -S -g

    from 72 to 35s, where gcc.c is from:

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

Author: Chris Lattner <sabre@nondot.org>
Date:   Tue Dec 29 02:14:09 2009 +0000

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

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

commit d11da6df1ecf393f637674081b24a631417321ed
Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Dec 28 23:41:32 2009 +0000

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

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

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

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

    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.

    Moving register scavenging to a post pass results in virtual registers in
    the instruction we're scavenging for. The scavenger needs to know to avoid
    them when analyzing register usage.

    with a 64-bit kernel, which confuses LLVM. Make LLVM double-check this by

    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.

    Extend the StartPassTimer and StopPassTimer functions so that the
    code that stops the timer doesn't have to search to find the timer
    object before it stops the timer. This avoids a lock acquisition
    and a few other things done with the timer running.

    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.

    implement and document support for filecheck variables.  This
    allows matching and remembering a string and then matching and
    verifying that the string occurs later in the file.

    Change X86/xor.ll to use this in some cases where the test was
    checking for an arbitrary register allocation decision.

    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

    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 verification of explicit operands.

    The machine code verifier did not check for explicit operands correctly. It

    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.

    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.

    %S0<def> = EXTRACT_SUBREG %Q0<kill>, 1
    to
    %S0<def> = IMPLICIT_DEF %Q0<imp-use,kill>

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

    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.

    improve memdep to eliminate bitcasts (and aliases, and noop geps)
    early for the stated reasons: this allows it to find more

    Move CoerceAvailableValueToLoadType earlier in GVN.cpp.  Hook it up
    so that nonlocal and partially redundant loads can use it as well.
    The testcase shows examples of craziness this can handle.  This triggers
    *many* times in 176.gcc.

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

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

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

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

    It's inefficient to have place the exception tables (which contain the LSDA)
    into the __DATA section. At launch time, dyld has to update most of the section
    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.

    Added the definitions for one-bit left shifts to

    The patterns will stay blank because ADD reg, reg
    is faster, but having the encoding available is
    useful for the disassembler.

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

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

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

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

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

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

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

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

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

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

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

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

    Change the marker byte for stubs from 0xcd to 0xce (another form of
    interrupt instruction, which shouldn't arise any other way).  0xcd is
    also used by JITMemoryManager to initialize the buffer to garbage,

    that is not a stub, confusing X86CompilationCallback2.  PR 4929.

commit 19f0725ebd200ab818b0431a64943eebf61c794d
Author: Bob Wilson <bob.wilson@apple.com>
Date:   Tue Sep 15 17:56:18 2009 +0000

    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.

    Pull the creation of the "RewindFunction" function out of the loop. It's only
    created once, so shouldn't be stuck in the middle of the loop. Also early exit
    if there are no uses of UnwindInst in the function.

    Change MCAsmStreamer to take an MCInstPrinter instead of a
    full AsmPrinter, and change TargetRegistry to keep track
    of registered MCInstPrinters.

    llvm-mc is still linking in the entire
    target foo to get the code emitter stuff, but this is an
    important step in the right direction.

    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.

    split MCInst printing out of the X86ATTInstPrinter
    class into its own X86ATTInstPrinter class.  The inst

Author: Dan Gohman <gohman@apple.com>
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.

    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.

    is not the same as "inbounds") from GlobalOpt into a utility routine,
    and use it in ConstantFold.cpp to check whether there are any mis-behaved
    indices.

    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

    splits that are made to preserve LoopSimplify form, but also for the

    can be used for both. Remove LoopRotation.cpp's code for manually

    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
    ignore changes in its LLVMContext argument and always return a type constructed
    from the argument to the first call.

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

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

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

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

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

Author: Dan Gohman <gohman@apple.com>
Date:   Mon Sep 7 23:47:14 2009 +0000

    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.

Author: Dan Gohman <gohman@apple.com>
Date:   Mon Sep 7 22:44:55 2009 +0000

    Don't commit stores with addresses that have indices that are not
    compile-time constant integers or that are out of bounds for their
    corresponding static array types. These can cause aliasing that
    GlobalOpt assumes won't happen.

    Don't commit addresses of aggregate values. This avoids problems with
    an aggregate store overlapping a different aggregate store, despite

Author: Dan Gohman <gohman@apple.com>
Date:   Mon Sep 7 22:40:13 2009 +0000

    Fix GlobalOpt to avoid committing a store if the address getelementptr
    is missing the inbounds flag. This is slightly conservative, but it
    avoids problems with two constants pointing to the same address but
    getting distinct entries in the Memory DenseMap.

    Now that googletest can print ConstantRange, use EXPECT_EQ when testing for
    equality. Prefer EXPECT_EQ(foo, Full) over EXPECT_TRUE(foo.isFullSet()) because
    the former will print out the contents of the constant range that failed.

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

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

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

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

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

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

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

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

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

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

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

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

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

    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).

    edge-profiling, this is more useful since the loading of the

    desired triplet is a sub-target, e.g. thumbv7 vs. arm host). Reverting the

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

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

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

    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.

    If the tied registers are already the same, there is no need to change
    them.  Move the code to make that change inside the conditional.

    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.
