VPADDSB xmm {k}, xmm, xmm
Synopsis
 _mm_mask_adds_epi8(__m128i src, __mmask16 k, __m128i a, __m128i b);
Description
Add packed signed 8-bit integers in "a" and "b" using saturation, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
	i := j*8
	IF k[j]
		dst[i+7:i] := Saturate8( a[i+7:i] + b[i+7:i] )
	ELSE
		dst[i+7:i] := src[i+7:i]
	FI
ENDFOR
dst[MAX:128] := 0
