Synopsis
_mm256_mask_min_epu8(__m256i src, __mmask32 k, __m256i a, __m256i b);
Description
Compare packed unsigned 8-bit integers in "a" and "b", and store packed minimum values in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 31
i := j*8
IF k[j]
dst[i+7:i] := MIN(a[i+7:i], b[i+7:i])
ELSE
dst[i+7:i] := src[i+7:i]
FI
ENDFOR
dst[MAX:256] := 0
