Function core::arch::x86::_mm256_mask_expand_epi16

pub unsafe fn _mm256_mask_expand_epi16(
    src: __m256i, 
    k: __mmask16, 
    a: __m256i
) -> __m256i

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

This is supported on x86 and target feature avx512vbmi2,avx512vl only.

Load contiguous active 16-bit integers from a (those with their respective bit set in mask k), and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
