Function core::arch::x86::_mm256_maskz_permutex_epi64

pub unsafe fn _mm256_maskz_permutex_epi64<const MASK: i32>(
    k: __mmask8, 
    a: __m256i
) -> __m256i

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

This is supported on x86 and target feature avx512f,avx512vl only.

Shuffle 64-bit integers in a within 256-bit lanes using the control in imm8, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
