Function core::arch::x86::_mm256_maskz_permutexvar_epi64

pub unsafe fn _mm256_maskz_permutexvar_epi64(
    k: __mmask8, 
    idx: __m256i, 
    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 across lanes using the corresponding index in idx, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
