Synopsis
_mm256_mask_andnot_pd(__m256d src, __mmask8 k, __m256d a, __m256d 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 writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 3
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] := src[i+63:i]
FI
ENDFOR
dst[MAX:256] := 0
