[PATCH] D67678: PR17164: Change clang's default behavior from -flax-vector-conversions=all to -flax-vector-conversions=integer.

[Steven Wu via Phabricator via cfe-commits]

steven_wu added a comment.

@rsmith This also breaks macOS SDK. Can we revert this as we discuss a less aggressive option?

Here is an example in macOS SDK (from /usr/include/simd/logic.h):

  static inline SIMD_CFUNC simd_bool simd_any(simd_int2 x) {
    return (_mm_movemask_ps(simd_make_int4_undef(x)) & 0x3);
  }

This change will cause problem for people using TOT clang with macOS SDK. Maybe we can start with warning or provide a toolchain overwrite for this?
