Function core::arch::x86::_mm_mask2_permutex2var_epi16

pub unsafe fn _mm_mask2_permutex2var_epi16(
    a: __m128i, 
    idx: __m128i, 
    k: __mmask8, 
    b: __m128i
) -> __m128i

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

This is supported on x86 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).
