Function surge_halfrate::imports::_mm512_mask_permutex2var_epi64

pub unsafe fn _mm512_mask_permutex2var_epi64(
    a: __m512i, 
    k: u8, 
    idx: __m512i, 
    b: __m512i
) -> __m512i

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

This is supported with target feature avx512f only.

Shuffle 64-bit integers in a and b across lanes using the corresponding selector and index in idx, and store the results in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
