    'self' was previously never tracked, but now it can be tracked
    because it may be part of a condition. (detail)

  4. Add -Wbitwise-conditional-parentheses to warn on mixing '|' and '&' with "?:"

    Extend -Wparentheses to cover mixing bitwise-and and bitwise-or with the
    conditional operator. There's two main cases seen with this:

    unsigned bits1 = 0xf0 | cond ? 0x4 : 0x1;
    unsigned bits2 = cond1 ? 0xf0 : 0x10 | cond2 ? 0x5 : 0x2;

    // Intended order of evaluation:
    unsigned bits1 = 0xf0 | (cond ? 0x4 : 0x1);
    unsigned bits2 = (cond1 ? 0xf0 : 0x10) | (cond2 ? 0x5 : 0x2);

    // Actual order of evaluation:
    unsigned bits1 = (0xf0 | cond) ? 0x4 : 0x1;
    unsigned bits2 = cond1 ? 0xf0 : ((0x10 | cond2) ? 0x5 : 0x2);

  7. AMDGPU: Remove optnone from a test

    It's not clear why the test had this. I'm unable to break the original
    case with the original patch reverted with or without optnone.

  10. New tautological warning for bitwise-or with non-zero constant always true.

    Taking a value and the bitwise-or it with a non-zero constant will always
    result in a non-zero value. In a boolean context, this is always true.

    if (x | 0x4) {}  // always true, intended '&'

    This patch creates a new warning group -Wtautological-bitwise-compare for this
    warning. It also moves in the existing tautological bitwise comparisons into
    this group. A few other changes were needed to the CFGBuilder so that all bool
    contexts would be checked. The warnings in -Wtautological-bitwise-compare will
    be off by default due to using the CFG.

  11. [profile] Use -fPIC -shared in a test instead of -dynamiclib

    This is more portable than -dynamiclib. Also, fix the path to an input

  12. Move endian constant from Host.h to SwapByteOrder.h, prune include

    Works on this dependency chain:
      ArrayRef.h ->
      Hashing.h -> --CUT--
      Host.h ->
      StringMap.h / StringRef.h

    ArrayRef is very popular, but Host.h is rarely needed. Move the
    IsBigEndianHost constant to SwapByteOrder.h. Clients of that header are
    more likely to need it. (detail)

  14. Sema: Create a no-op implicit cast for lvalue function conversions.

    This fixes an assertion failure in the case where an implicit conversion for a
    function call involves an lvalue function conversion, and makes the AST for
    initializations involving implicit lvalue function conversions more accurate.

  17. [hip][cuda] Fix the extended lambda name mangling issue.

    - HIP/CUDA host side needs to use device kernel symbol name to match the
      device side binaries. Without a consistent naming between host- and
      device-side compilations, it's risky that wrong device binaries are
      executed. Consistent naming is usually not an issue until unnamed
      types are used, especially the lambda. In this patch, the consistent
      name mangling is addressed for the extended lambdas, i.e. the lambdas
      annotated with `__device__`.
    - In [Itanium C++ ABI][1], the mangling of the lambda is generally
      unspecified unless, in certain cases, ODR rule is required to ensure
      consisent naming cross TUs. The extended lambda is such a case as its
      name may be part of a device kernel function, e.g., the extended
      lambda is used as a template argument and etc. Thus, we need to force
      ODR for extended lambdas as they are referenced in both device- and
      host-side TUs. Furthermore, if a extended lambda is nested in other
      (extended or not) lambdas, those lambdas are required to follow ODR
      naming as well. This patch revises the current lambda mangle numbering
      to force ODR from an extended lambda to all its parent lambdas.
    - On the other side, the aforementioned ODR naming should not change
      those lambdas' original linkages, i.e., we cannot replace the original
      `internal` with `linkonce_odr`; otherwise, we may violate ODR in
      general. This patch introduces a new field `HasKnownInternalLinkage`
      in lambda data to decouple the current linkage calculation based on
      mangling number assigned.

  20. [c++20] Add rewriting from comparison operators to <=> / ==.

    This adds support for rewriting <, >, <=, and >= to a normal or reversed
    call to operator<=>, for rewriting != to a normal or reversed call to
    operator==, and for rewriting <=> and == to reversed forms of those same

    Note that this is a breaking change for various C++17 code patterns,
    including some in use in LLVM. The most common patterns (where an
    operator== becomes ambiguous with a reversed form of itself) are still
    accepted under this patch, as an extension (with a warning). I'm hopeful
    that we can get the language rules fixed before C++20 ships, and the
    extension warning is aimed primarily at providing data to inform that
    decision. (detail)

  23. [profile] Do not cache __llvm_profile_get_filename result

    When the %m filename pattern is used, the filename is unique to each
    image, so the cached value is wrong.

    It struck me that the full filename isn't something that's recomputed
    often, so perhaps it doesn't need to be cached at all. David Li pointed
    out we can go further and just hide lprofCurFilename. This may regress
    workflows that depend on using the set-filename API to change filenames
    across all loaded DSOs, but this is expected to be very rare.

    If a subregister def was moved across another subregister def and

  29. [SampleFDO] Add profile remapping support for profile on-demand loading used
    by ExtBinary format profile

    Profile on-demand loading was added for ExtBinary format profile in rL374233,
    but currently profile on-demand loading doesn't work well with profile
    remapping. The patch adds the support.

    Suppose a function in the current module has outline instance in the profile.
    The function name in the module is different from the name of the outline
    instance, but remapper knows the two names are equal. When loading profile
    on-demand, the outline instance has to be loaded with remapper's help.

    At the same time SampleProfileReaderItaniumRemapper is changed from a proxy
    of SampleProfileReader to a helper member in SampleProfileReader.
