Function core::arch::x86::_mm512_mask_multishift_epi64_epi8

pub unsafe fn _mm512_mask_multishift_epi64_epi8(
    src: __m512i,
    k: __mmask64,
    a: __m512i,
    b: __m512i
) -> __m512i

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

Available on (x86 or x86-64) and target feature avx512vbmi 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 writemask k (elements are copied from src when the corresponding mask bit is not set).
