Function core::arch::x86::_mm_maskz_multishift_epi64_epi8

pub unsafe fn _mm_maskz_multishift_epi64_epi8(
    k: __mmask16, 
    a: __m128i, 
    b: __m128i
) -> __m128i

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

This is supported on x86 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).
