Changes
  1. [test][AArch64] Relax the opcode tests for FP min/max instructions. (detail/ViewSVN)
    by dyung
  2. Add option to disable variant narrowing conversion changes.

    The paper P0608R3 - "A sane variant converting constructor" disallows
    narrowing conversions in variant. It was meant to address this
    surprising problem:

      std::variant<std::string, bool> v = "abc";
      assert(v.index() == 1); // constructs a bool.

    However, it also disables every potentially narrowing conversion. For
    example:

      variant<unsigned> v = 0; // ill-formed
      variant<string, double> v2 = 42; // ill-formed (int -> double narrows)

    These latter changes break code. A lot of code. Within Google it broke
    on the order of a hundred thousand target with thousands of root causes
    responsible for the breakages.

    Of the breakages related to the narrowing restrictions, none of them
    exposed outstanding bugs. However, the breakages caused by boolean
    conversions (~13 root causes), all but one of them were bugs.

    For this reasons, I am adding a flag to disable the narrowing conversion
    changes but not the boolean conversions one.

    One purpose of this flag is to allow users to opt-out of breaking changes
    in variant until the offending code can be cleaned up. For non-trivial
    variant usages the amount of cleanup may be significant.

    This flag is also required to support automated tooling, such as
    clang-tidy, that can automatically fix code broken by this change.
    In order for clang-tidy to know the correct alternative to construct,
    it must know what alternative was being constructed previously, which
    means running it over the old version of std::variant.

    Because this change breaks so much code, I will be implementing the
    aforementioned clang-tidy check in the very near future.

    Additionally I'm plan present this new information to the committee so they can
    re-consider if this is a breaking change we want to make.

    I think libc++ should very seriously consider pulling this change
    before the 9.0 release branch is cut. But that's a separate discussion
    that I will start on the lists.

    For now this is the minimal first step. (detail/ViewSVN)

  3. [InstCombine] Disable fold from D64285 for non-integer types (detail/ViewSVN)
    by xbolva00
  4. Factor out resolveFrameOffsetReference (NFC).

    Split AArch64FrameLowering::resolveFrameIndexReference in two parts
    * Finding frame offset for the index.
    * Finding base register and offset to that register.

    The second part will be used to implement a virtual frame pointer in
    armv8.5 MTE stack instrumentation lowering.

  5. [builtins] Fix assembly in arm sync-ops.h

    This assembly is part of a macro that was reformatted in D60351.
    The missing space between push and { results in:

        Error: bad instruction `push{r4, r5,r6,lr}' (detail/ViewSVN)
    by nikic
  6. Revert driver: Don't warn about assembler flags being unused when not assembling

    This reverts r365703 (git commit 101c1afdfd1c88f05da94c6fd317b489bb704f40)
    and r365714.

    This broke some autoconf-style assembler flags checks in the Linux
    build:

  7. [clangd] Fix off-by-one in CodeComplete and assertion in Dex (detail/ViewSVN)
    by sammccall
  8. Reland [clang] DirectoryWatcher

    This reverts commit f561227d133224d2d6a5a016abe4be051fa75501.

    - DirectoryWatcher
    - Fix the build for platforms that don't have DW implementated.
    - Fix the threading dependencies (thanks to compnerd). (detail/ViewSVN)
