  1. [TargetLowering] SimplifyMultipleUseDemandedBits - add VECTOR_SHUFFLE support.

    If all the demanded elts are from one operand and are inline, then we can use the operand directly.

    The changes are mainly from SSE41 targets which has blendvpd but not cmpgtq, allowing the v2i64 comparison to be simplified as we only need the signbit from alternate v4i32 elements. (detail/ViewSVN)

  2. Revert "[Object/ELF.h] - Improve testing of the fields in ELFFile<ELFT>::sections()."

    This reverts commit r366796 because it was causing ubsan buildbot
    failures. (detail/ViewSVN)

  3. [llvm-ar] Fix support for archives with members larger than 4GB

    llvm-ar outputs a strange error message when handling archives with
    members larger than 4GB due to not checking file size when passing the
    value as an unsigned 32 bit integer. This overflow issue caused
    malformed archives to be created.:

    This change allows for members above 4GB and will error in a case that
    is over the formats size limit, a 10 digit decimal integer.

  5. [ARM][LowOverheadLoops] Fix branch target codegen
    While lowering test.set.loop.iterations, it wasn't checked how the
    brcond was using the result and so the wls could branch to the loop
    preheader instead of not entering it. The same was true for
    So brcond and br_cc and now lowered manually when using the hwloop
    intrinsics. During this we now check whether the result has been
    negated and whether we're using SETEQ or SETNE and 0 or 1. We can
    then figure out which basic block the WLS and LE should be targeting.

  7. [SLPVectorizer] Revert local change that got accidently got committed in rL366799

    This wasn't part of D63281 (detail/ViewSVN)

  8. Revert [RISCV] Re-enable rv32i-aliases-invalid.s test

    This reverts r366797 (git commit 53f9fec8e8b58f5a904bbfb4a1d648cde65aa860) (detail/ViewSVN)

  9. [NFC][ASAN] Add brackets around not command

    Under certain execution conditions, the `not` command binds to the command the
    output is piped to rather than the command piping the output. In this case, that
    flips the return code of the FileCheck invocation, causing a failure when
    FileCheck succeeds. (detail/ViewSVN)

  10. [NFC][InstCombine] Fixup commutative/negative tests with icmp preds in @llvm.umul.with.overflow tests (detail/ViewSVN)
    by lebedevri
  11. [InstSimplify][NFC] Tests for skipping 'div-by-0' checks before inverted @llvm.umul.with.overflow

    It would be already handled by the non-inverted case if we were hoisting
    the `not` in InstCombine, but we don't (granted, we don't sink it
    in this case either), so this is a separate case. (detail/ViewSVN)
    by lebedevri
  12. [NFC][PhaseOredering][SimplifyCFG] Add more runlines to umul.with.overflow tests

    This way it will be more obvious that the problem is both
    in cost threshold and in hardcoded benefit check,
    plus will show how the instsimplify cleans this all in the end. (detail/ViewSVN)
    by lebedevri
  13. [TargetLowering] Add SimplifyMultipleUseDemandedBits

    This patch introduces the DAG version of SimplifyMultipleUseDemandedBits, which attempts to peek through ops (mainly and/or/xor so far) that don't contribute to the demandedbits/elts of a node - which means we can do this even in cases where we have multiple uses of an op, which normally requires us to demanded all bits/elts. The intention is to remove a similar instruction - SelectionDAG::GetDemandedBits - once SimplifyMultipleUseDemandedBits has matured.

    The InstCombine version of SimplifyMultipleUseDemandedBits can constant fold which I haven't added here yet, and so far I've only wired this up to some basic binops (and/or/xor/add/sub/mul) to demonstrate its use.

    We do see a couple of regressions that need to be addressed:

        AMDGPU unsigned dot product codegen retains an AND mask (for ZERO_EXTEND) that it previously removed (but otherwise the dotproduct codegen is a lot better).

        X86/AVX2 has poor handling of vector ANY_EXTEND/ANY_EXTEND_VECTOR_INREG - it prematurely gets converted to ZERO_EXTEND_VECTOR_INREG.

    The code owners have confirmed its ok for these cases to fixed up in future patches.

  14. [RISCV] Re-enable rv32i-aliases-invalid.s test

    We were getting test failures on some builders, which pointed to @LINE
    being an undefined variable. I think that these failures should have
    been fixed by, so I'm re-enabling the
    test. (detail/ViewSVN)

  15. [Object/ELF.h] - Improve testing of the fields in ELFFile<ELFT>::sections().

    This eliminates a one error untested and
    also introduces a error for one more possible case
    which lead to crash previously.
