pub const fn _mm256_mask_mulhi_epi16(src: __m256i, k: __mmask16, a: __m256i, b: __m256i) -> __m256iMultiply the packed signed 16-bit integers in a and b, producing intermediate 32-bit integers, and store the high 16 bits of the intermediate integers in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
