Synopsis
_mm256_maskz_andnot_epi64(__mmask8 k, __m256i a, __m256i b);
Description
Compute the bitwise NOT of packed 64-bit integers 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 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] := 0
FI
ENDFOR
dst[MAX:256] := 0
