Synopsis
_mm512_mask_andnot_epi64(__m512i src, __mmask8 k, __m512i a, __m512i 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 writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
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:512] := 0
