Synopsis
_mm256_mask_cmpneq_epi8_mask(__mmask32 k1, __m256i a, __m256i b);
Description
Compare packed signed 8-bit integers in "a" and "b" for not-equal, and store the results in mask vector "k" using zeromask "k1" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 31
i := j*8
IF k1[j]
k[j] := ( a[i+7:i] != b[i+7:i] ) ? 1 : 0
ELSE
k[j] := 0
FI
ENDFOR
k[MAX:32] := 0
