Function core::arch::x86::_mm512_mask_expand_epi8

pub unsafe fn _mm512_mask_expand_epi8(
    src: __m512i,
    k: __mmask64,
    a: __m512i
) -> __m512i

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on (x86 or x86-64) and target feature avx512vbmi2 and x86 only.

Load contiguous active 8-bit integers from a (those with their respective bit set in mask k), and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
