🔬This is a nightly-only experimental API. (`stdarch_x86_avx512` #111137)
Available on (x86 or x86-64) and target feature `avx512vnni` and x86-64 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, and store the packed 32-bit results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
