Function creusot_contracts::std::arch::x86_64::_mm512_dpwssds_epi32

pub unsafe fn _mm512_dpwssds_epi32(
    src: __m512i,
    a: __m512i,
    b: __m512i,
) -> __m512i

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

Available on x86-64 only.

Multiply groups of 2 adjacent pairs of signed 16-bit integers in a with corresponding 16-bit integers in b, producing 2 intermediate signed 32-bit results. Sum these 2 results with the corresponding 32-bit integer in src using signed saturation, and store the packed 32-bit results in dst.
