   [LoopReroll] Fix reroll root legality checking.
   
   The code checked that the first root was an appropriate distance from
   the base value, but skipped checking the other roots. This could lead to
   rerolling a loop that can't be legally rerolled (at least, not without
   rewriting the loop in a non-trivial way).

   DebugInfo: Split DWARF + gmlt + no-split-dwarf-inlining shouldn't emit anything to the .dwo file
   
   This configuration (due to r349207) was intended not to emit any DWO CU,
   but a degenerate CU was still being emitted - containing a header and a
   DW_TAG_compile_unit with no attributes.
   
   Under that situation, emit nothing to the .dwo file. (since this is a
   dynamic property of the input the .dwo file is still emitted, just with
   nothing in it (so a valid, but empty, ELF file) - if some other CU
   didn't satisfy this criteria, its DWO CU would still go there, etc)

    Be conservative about unordered accesses for the moment
    
    Background: As described in https://reviews.llvm.org/D57601, I'm working towards separating volatile and atomic in the MMO uses for atomic instructions.
    
    In https://reviews.llvm.org/D57593, I fixed a bug where isUnordered was returning the wrong result, but didn't account for the fact I was getting slightly ahead of myself. While both uses of isUnordered are correct (as far as I can tell), we don't have tests to demonstrate this and being aggressive gets in the way of having the removal of volatile truly be non-functional. Once D57601 lands, I will return to these call sites, revert this patch, and add the appropriate tests to show the expected behaviour.

    Comments

    [tblgen] Add a timer covering the time spent reading the Instruction defs
    
    This patch adds a -time-regions option to tablegen that can enable timers
    (currently only one) that assess the performance of tablegen itself. This
    can be useful for identifying scaling problems with tablegen backends.
    
    This particular timer has allowed me to ignore time that is not attributed
    the GISel combiner pass. It's useful by itself but it is particularly
    useful in combination with https://reviews.llvm.org/D52954 which causes
    this period of time to be annotated within Xcode Instruments which in turn
    allows profile samples and recorded allocations attributed to reading
    instructions to be filtered out.

    [LegalizeTypes] Expand FNEG to bitwise op for IEEE FP types
    
    Summary:
    Except for custom floating point types x86_fp80 and ppc_fp128,
    expand Y = FNEG(X) to Y = X ^ sign mask to avoid library call.
     Using bitwise operation can improve code size and performance.

    [X86] Correct the memory operand for the FLD emitted in FP_TO_INTHelper for 32-bit SSE targets.
    
    We were using DstTy, but that represents the integer type we are converting to which is i64 in this
    case. The FLD is part of an intermediate step to get from the SSE registers to the x87 registers.
    If the floating point type is f32, the memory operand should reflect a 4 byte access not an 8 byte
    access. The store we used to get from SSE to the stack is using the corect size.
    
    While there, consistenly use TheVT in place of Op.getOperand(0).getValueType() throughout the function.

    [llvm-cxxfilt] Split and demangle stdin input
    
    Summary:
    Originally, llvm-cxxfilt would treat a line as a single mangled item to be demangled.
    If a mangled name appears in the middle of that string, that name would not be demangled.
    
    GNU c++filt  splits and demangles every word  in a  string that is piped to it via stdin.
    Prior to this patch llvm-cxxfilt would never split strings  piped to it.
    This patch replicates the GNU behavior and splits strings that are piped to it via stdin.
    
    This fixes PR39990

    Refactor setAlreadyUnrolled() and setAlreadyVectorized().
    
    Loop::setAlreadyUnrolled() and
    LoopVectorizeHints::setLoopAlreadyUnrolled() both add loop metadata that
    stops the same loop from being transformed multiple times. This patch
    merges both implementations.
    
    In doing so we fix 3 potential issues:
    
     * setLoopAlreadyUnrolled() kept the llvm.loop.vectorize/interleave.*
       metadata even though it will not be used anymore. This already caused
       problems such as http://llvm.org/PR40546. Change the behavior to the
       one of setAlreadyUnrolled which deletes this loop metadata.
    
     * setAlreadyUnrolled() used to create a new LoopID by calling
       MDNode::get with nullptr as the first operand, then replacing it by
       the returned references using replaceOperandWith. It is possible
       that MDNode::get would instead return an existing node (due to
       de-duplication) that then gets modified. To avoid, use a fresh
       TempMDNode that does not get uniqued with anything else before
       replacing it with replaceOperandWith.
    
     * LoopVectorizeHints::matchesHintMetadataName() only compares the
       suffix of the attribute to set the new value for. That is, when
       called with "enable", would erase attributes such as
       "llvm.loop.unroll.enable", "llvm.loop.vectorize.enable" and
       "llvm.loop.distribute.enable" instead of the one to replace.
       Fortunately, function was only called with "isvectorized".

    [InstCombine] Fix matchRotate bug when one operand is a ConstantExpr shift
    
    This bug seems to be harmless in release builds, but will cause an error in UBSAN
    builds or an assertion failure in debug builds.
    
    When it gets to this opcode comparison, it assumes both of the operands are BinaryOperators,
    but the prior m_LogicalShift will also match a ConstantExpr. The cast<BinaryOperator> will
    assert in a debug build, or reading an invalid value for BinaryOp from memory with
    ((BinaryOperator*)constantExpr)->getOpcode() will cause an error in a UBSAN build.
    
    The test I added will fail without this change in debug/UBSAN builds, but not in release.

    [SelectionDAGBuilder] Add restrictions to EmitFuncArgumentDbgValue
    
    Summary:
    This patch fixes PR40587.
    
    When a dbg.value instrinsic is emitted to the DAG
    by using EmitFuncArgumentDbgValue the resulting
    DBG_VALUE is hoisted to the beginning of the entry
    block. I think the idea is to be able to locate
    a formal argument already from the start of the
    function.
    However, EmitFuncArgumentDbgValue only checked that
    the value that was used to describe a variable was
    originating from a function parameter, not that the
    variable itself actually was an argument to the
    function. So when for example assigning a local
    variable "local" the value from an argument "a",
    the assocated DBG_VALUE instruction would be hoisted
    to the beginning of the function, even if the scope
    for "local" started somewhere else (or if "local"
    was mapped to other values earlier in the function).
    
    This patch adds some logic to EmitFuncArgumentDbgValue
    to check that the variable being described actually
    is an argument to the function. And that the dbg.value
    being lowered already is in the entry block. Otherwise
    we bail out, and the dbg.value will be handled as an
    ordinary dbg.value (not as a "FuncArgumentDbgValue").
    
    A tricky situation is when both the variable and
    the value is related to function arguments, but not
    neccessarily the same argument. We make sure that we
    do not describe the same argument more than once as
    a "FuncArgumentDbgValue". This solution works as long
    as opt has injected a "first" dbg.value that corresponds
    to the formal argument at the function entry.

    [DebugInfo] Fix /usr/lib/debug llvm-symbolizer lookup with relative paths
    
    Summary:
    rL189250 added a realpath call, and rL352916 because realpath breaks assumptions with some build systems. However, the /usr/lib/debug case has been clarified, falling back to /usr/lib/debug is currently broken if the obj passed in is a relative path. Adding a call to use absolute paths when falling back to /usr/lib/debug fixes that while still not making any realpath assumptions.
    
    This also adds a --fallback-debug-path command line flag for testing (since we probably can't write to /usr/lib/debug from buildbot environments), but was also verified manually:
    
    ```
    $ rm -f path/to/dwarfdump-test.elf-x86-64
    $ strace llvm-symbolizer --obj=relative/path/to/dwarfdump-test.elf-x86-64.debuglink 0x40113f |& grep dwarfdump
    ```
    
    Lookups went to relative/path/to/dwarfdump-test.elf-x86-64, relative/path/to/.debug/dwarfdump-test.elf-x86-64, and then finally /usr/lib/debug/absolute/path/to/dwarfdump-test.elf-x86-64.

    [MCA][Scheduler] Track resources that were found busy when issuing an instruction.
    
    This is a follow up of r353706. When the scheduler fails to issue a ready
    instruction to the underlying pipelines, it now updates a mask of 'busy resource
    units'. That information will be used in future to obtain the set of
    "problematic" resources in the case of bottlenecks caused by resource pressure.
    No functional change intended.

    Add some common recipes for downstream users developing on top of the
    existing git mirrors. These instructions show how to migrate local
    branches to the monorepo.

    [MCA] Return a mask of busy resources from method ResourceManager::checkAvailability(). NFCI
    
    In case of bottlenecks caused by pipeline pressure, we want to be able to
    correctly report the set of problematic pipelines. This is a first step towards
    adding support for bottleneck hints in llvm-mca (see PR37494). No functional
    change intended.

    [AMDGPU] Fix DPP sequence in atomic optimizer.
    
    This commit fixes the DPP sequence in the atomic optimizer (which was
    previously missing the row_shr:3 step), and works around a read_register
    exec bug by using a ballot instead.
