Instruction
VPMAXUD xmm {k}, xmm, xmm
Synopsis
_mm_mask_max_epu32(__m128i src, __mmask8 k, __m128i a, __m128i b);
Description
Compare packed unsigned 32-bit integers in "a" and "b", and store packed maximum values in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 3
i := j*32
IF k[j]
dst[i+31:i] := MAX(a[i+31:i], b[i+31:i])
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:128] := 0
