Function core::arch::x86_64::_mm256_mask2_permutex2var_epi16

pub unsafe fn _mm256_mask2_permutex2var_epi16(
    a: __m256i, 
    idx: __m256i, 
    k: __mmask16, 
    b: __m256i
) -> __m256i

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

Available on x86-64 and target feature avx512bw,avx512vl only.

Shuffle 16-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 idx when the corresponding mask bit is not set).
