Function no_std_compat::arch::x86_64::_mm_mask_madd_epi16

pub unsafe fn _mm_mask_madd_epi16(
    src: __m128i,
    k: u8,
    a: __m128i,
    b: __m128i,
) -> __m128i

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

Available on x86-64 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).
