Synopsis
_mm512_mask_cmpeq_epu32_mask(__mmask16 k1, __m512i a, __m512i b);
Description
Compare packed unsigned 32-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*32
IF k1[j]
k[j] := ( a[i+31:i] == b[i+31:i] ) ? 1 : 0
ELSE
k[j] := 0
FI
ENDFOR
k[MAX:16] := 0
