pub fn _mm512_mask_cvtneps_pbh(src: __m256bh, k: __mmask16, a: __m512) -> __m256bh

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