--- Comment #2 from LIU Hao <lh_mouse at 126 dot com> ---
Intel's choice that `_mm_cmpistri()` should return `int` is just awkward. The
result has always been zero-extended to RCX; similarly for `PMOVMSK` (with AVX,
`VPMOVMSKB` produces a 32-bit result which is still zero-extended).
For Clang, casting the result to `uint32_t` is sufficient to eliminate the
zero-extension; for GCC it does not work.
