Instruction
VMOVAPD ymm {z}, m256
Synopsis
 _mm256_maskz_load_pd(__mmask8 k, void const* mem_addr);
Description
Load packed double-precision (64-bit) floating-point elements from memory into "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set). "mem_addr" must be aligned on a 32-byte boundary or a general-protection exception may be generated.
Operation
FOR j := 0 to 3
	i := j*64
	IF k[j]
		dst[i+63:i] := MEM[mem_addr+i+63:mem_addr+i]
	ELSE
		dst[i+63:i] := 0
	FI
ENDFOR
dst[MAX:256] := 0
