VCVTPD2PH xmm {k}, ymm
Synopsis
 _mm256_mask_cvtpd_ph(__m128h src, __mmask8 k, __m256d a);
Description
Convert packed double-precision (64-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" when the corresponding mask bit is not set). The upper 64 bits of "dst" are zeroed out.
Operation
FOR j := 0 TO 3
	IF k[j]
		dst.fp16[j] := Convert_FP64_To_FP16(a.fp64[j])
	ELSE
		dst.fp16[j] := src.fp16[j]
	FI
ENDFOR
dst[MAX:64] := 0
