Instruction
VCVTDQ2PD ymm {z}, xmm
Synopsis
 _mm256_maskz_cvtepi32_pd(__mmask8 k, __m128i a);
Description
Convert packed signed 32-bit integers in "a" to packed double-precision (64-bit) floating-point elements, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 3
	i := j*32
	m := j*64
	IF k[j]
		dst[m+63:m] := Convert_Int32_To_FP64(a[i+31:i])
	ELSE
		dst[m+63:m] := 0
	FI
ENDFOR
dst[MAX:256] := 0
