Function core::arch::x86_64::_mm_mask_madd_epi16

pub unsafe fn _mm_mask_madd_epi16(
    src: __m128i,
    k: __mmask8,
    a: __m128i,
    b: __m128i
) -> __m128i

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

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

Multiply packed signed 16-bit integers in a and b, producing intermediate signed 32-bit integers. Horizontally add adjacent pairs of intermediate 32-bit integers, and pack the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
