    pub unsafe fn _mm_dpwssds_epi32(src: __m128i, a: __m128i, b: __m128i) -> __m128i

🔬This is a nightly-only experimental API. (`stdsimd` #48556)
Available on (x86 or x86-64) and target feature `avx512vnni,avx512vl` only.
Expand description

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.
