Synopsis
_mm512_test_epi32_mask(__m512i a, __m512i b);
Description
Compute the bitwise AND of packed 32-bit integers in "a" and "b", producing intermediate 32-bit values, and set the corresponding bit in result mask "k" if the intermediate value is non-zero.
Operation
FOR j := 0 to 15
i := j*32
k[j] := ((a[i+31:i] AND b[i+31:i]) != 0) ? 1 : 0
ENDFOR
k[MAX:16] := 0
