Function core::arch::x86::_mm512_mask_cvtepi8_epi16

pub unsafe fn _mm512_mask_cvtepi8_epi16(
    src: __m512i,
    k: __mmask32,
    a: __m256i
) -> __m512i

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

Available on x86 and target feature avx512bw only.

Sign extend packed 8-bit integers in a to packed 16-bit integers, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
