Author: Benjamin Kramer <benny.kra@googlemail.com>
Date:   Mon Dec 28 12:27:56 2009 +0000

    Add missing include (for inline PATypeHolder::get).

    git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92222 91177308-0d34-0410-b5e6-96231b3b80d8

Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Dec 28 09:24:53 2009 +0000

    Eliminate two bits of ugliness in MDNode::replaceElement:
    eliminate the temporary smallvector, and only do FindNodeOrInsertPos
    twice if the first one succeeds and we delete a node.

commit 3716bc64a3ee906a6e40e6847ac915daa01e4919
Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Dec 28 09:07:21 2009 +0000

    Rewrite the function-local validation logic for MDNodes (most of r91708).
    Among other benefits, this doesn't leak the SmallPtrSet, has the verifier
    code in the verifier pass, actually does the verification at the end,
    and is considerably simpler.

    change NamedMDNode to use a pimpl for its operand list instead
    of making it a declared part of the value.

Author: Chris Lattner <sabre@nondot.org>
Date:   Mon Dec 28 07:41:54 2009 +0000

    move ElementVH out of the MDNode class into the MDNode.cpp file.  Among
    other things, this avoids vtable and rtti data for it being splatted in
    every translation unit that uses it.

    Add an "ATTRIBUTE_UNUSED" macro (and use it). It's for variables which are
    mainly used in debugging and/or assert situations. It should make the compiler
    and the static analyzer stop nagging us about them.

    Move the two definitions of operator<< into namespace llvm, so they
    will be found by argument-dependent lookup. As with the previous
    commit, GCC is allowing ill-formed code.

Date:   Thu Dec 24 21:11:45 2009 +0000

    Define the new operator<< for sets into namespace std, so that
    argument-dependent lookup can find it. This is another case where an
    LLVM bug (not making operator<< visible) was masked by a GCC bug
    (looking in the global namespace when it shouldn't).

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

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

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

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

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

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

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

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

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

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

    covered by anything else in the test suite.

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

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

    This fixes rdar://6864035

    return partial registers. This affected the back-end lowering code some.

    Also patch up some places I missed before in the "get" functions.

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

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

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

    enhance x-(-A) -> x+A to preserve NUW/NSW.

    Use the presence of NSW/NUW to fold "icmp (x+cst), x" to a constant in
    cases where it would otherwise be undefined behavior.

    Surprisingly (to me at least), this triggers hundreds of the times in
    a few benchmarks: lencode, ldecode, and 466.h264ref seem to *really*
    like this.

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

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

    The disassembler is documented in detail in

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

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

    Changes from review:

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

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

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

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

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

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

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

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

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

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

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

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

    instead of
    cvtss2sd (%rdi), %xmm0

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

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

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

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

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

    Reuse lowered phi nodes.

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

    Teach LiveIntervalAnalysis about the phi joins with multiple uses.

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

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

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

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

    indirect global writable and then executable on ARM, but that shouldn't be
    necessary.

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

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

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

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

    This is the meat of that fix:

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

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

    Simplify this class by removing the result cache.

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

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

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

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

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

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

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

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

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

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

    Added a new "splitting" spiller.

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

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

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

Author: Chris Lattner <sabre@nondot.org>

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

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

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

    3. We have a lot less code in memdep.

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

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

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

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

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

    Dynamic stack realignment use of sp register as source/dest register

    Handle forwarding local memsets to loads.  For example, we optimize this:

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

    to 'return 257' instead of doing the load.

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

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

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

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

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

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

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

    Move PHIElimination::isLiveOut method to LiveVariables.

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

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

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

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

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

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

    becomes:

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

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

    Reprioritize tests for tail duplication to be aggressive about indirect

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

    Only print edgeSourceLabels if they are not empty

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

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

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

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

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

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

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

    add two simple test cases we now optimize (to one load in the loop each) and one we don't (corresponding to the fixme I added yesterday).

    This testcase is actually only partially redundant, and requires
    the FIXME I added yesterday to be implemented.

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

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

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