Instruction
VANDNPD xmm {z}, xmm, xmm
Synopsis
 _mm_maskz_andnot_pd(__mmask8 k, __m128d a, __m128d b);
Description
Compute the bitwise NOT of packed double-precision (64-bit) floating-point elements in "a" and then AND with "b", 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 1
	i := j*64
	IF k[j]
		dst[i+63:i] := ((NOT a[i+63:i]) AND b[i+63:i])
	ELSE
		dst[i+63:i] := 0
	FI
ENDFOR
dst[MAX:128] := 0
