VPCMPW k {k}, xmm, xmm
Synopsis
_mm_mask_cmpeq_epi16_mask(__mmask8 k1, __m128i a, __m128i b);
Description
Compare packed signed 16-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 7
i := j*16
IF k1[j]
k[j] := ( a[i+15:i] == b[i+15:i] ) ? 1 : 0
ELSE
k[j] := 0
FI
ENDFOR
k[MAX:8] := 0
