pub fn _mm256_mask_cvtne2ps_pbh(src: __m256bh, k: __mmask16, a: __m256, b: __m256) -> __m256bh

Convert packed single-precision (32-bit) floating-point elements in two vectors a and b to packed BF16 (16-bit) floating-point elements and store the results in single vector dst using writemask k (elements are copied from src when the corresponding mask bit is not set). Intel's documentation
