Function _mm512_mask_expand_epi16

pub fn _mm512_mask_expand_epi16(src: __m512i, k: u32, a: __m512i) -> __m512i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

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).
