Synopsis
_mm256_mask_cmpgt_epu32_mask(__mmask8 k1, __m256i a, __m256i b);
Description
Compare packed unsigned 32-bit integers in "a" and "b" for greater-than, 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 7
i := j*32
IF k1[j]
k[j] := ( a[i+31:i] > b[i+31:i] ) ? 1 : 0
ELSE
k[j] := 0
FI
ENDFOR
k[MAX:8] := 0
