VPTESTMW k {k}, xmm, xmm
Synopsis
_mm_mask_test_epi16_mask(__mmask8 k1, __m128i a, __m128i b);
Description
Compute the bitwise AND of packed 16-bit integers in "a" and "b", producing intermediate 16-bit values, and set the corresponding bit in result mask "k" (subject to writemask "k") if the intermediate value is non-zero.
Operation
FOR j := 0 to 7
i := j*16
IF k1[j]
k[j] := ((a[i+15:i] AND b[i+15:i]) != 0) ? 1 : 0
ELSE
k[j] := 0
FI
ENDFOR
k[MAX:8] := 0
