Synopsis
_mm256_maskz_or_epi64(__mmask8 k, __m256i a, __m256i b);
Description
Compute the bitwise OR of packed 64-bit integers in "a" and "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] := a[i+63:i] OR b[i+63:i]
ELSE
dst[i+63:i] := 0
FI
ENDFOR
dst[MAX:256] := 0
