Function core::arch::x86::_mm512_maskz_permutex2var_epi8

pub unsafe fn _mm512_maskz_permutex2var_epi8(
    k: __mmask64, 
    a: __m512i, 
    idx: __m512i, 
    b: __m512i
) -> __m512i

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

This is supported on x86 and target feature avx512vbmi only.

Shuffle 8-bit integers in a and b across lanes using the corresponding selector and index in idx, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
