Function core::arch::x86::_mm256_maskz_multishift_epi64_epi8

pub unsafe fn _mm256_maskz_multishift_epi64_epi8(
    k: __mmask32,
    a: __m256i,
    b: __m256i
) -> __m256i

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

Available on (x86 or x86-64) and target feature avx512vbmi,avx512vl only.

For each 64-bit element in b, select 8 unaligned bytes using a byte-granular shift control within the corresponding 64-bit element of a, and store the 8 assembled bytes to the corresponding 64-bit element of dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
