Instruction
VPCMPB k {k}, xmm, xmm
Synopsis
 _mm_mask_cmpeq_epi8_mask(__mmask16 k1, __m128i a, __m128i b);
Description
Compare packed signed 8-bit integers in "a" and "b" for equality, 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 15
	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:16] := 0
