Function core::arch::x86_64::_mm_maskz_permutex2var_epi8

pub unsafe fn _mm_maskz_permutex2var_epi8(
    k: __mmask16, 
    a: __m128i, 
    idx: __m128i, 
    b: __m128i
) -> __m128i

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

This is supported on x86-64 and target feature avx512vbmi,avx512vl 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).
