#[target_feature(enable = "avx512fp16", enable = "avx512vl")]
pub fn _mm256_mask_cvtxps_ph(src: __m128h, k: __mmask8, a: __m256) -> __m128h

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