Function core::arch::x86::_mm256_mask_expand_epi8

pub unsafe fn _mm256_mask_expand_epi8(
    src: __m256i,
    k: __mmask32,
    a: __m256i
) -> __m256i

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

Available on (x86 or x86-64) and target feature avx512vbmi2,avx512vl 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).
