Function core_arch::x86::_mm_movemask_pi8

pub unsafe fn _mm_movemask_pi8(a: __m64) -> i32

🔬 This is a nightly-only experimental API. (stdsimd)

This is supported on x86 and target feature sse,mmx only.

Takes the most significant bit from each 8-bit element in a 64-bit integer vector to create a 16-bit mask value. Zero-extends the value to 32-bit integer and writes it to the destination.
