Synopsis
_mm512_mask_conflict_epi32(__m512i src, __mmask16 k, __m512i a);
Description
Test each 32-bit element of "a" for equality with all other elements in "a" closer to the least significant bit using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set). Each element's comparison forms a zero extended bit vector in "dst".
Operation
FOR j := 0 to 15
i := j*32
IF k[j]
FOR l := 0 to j-1
m := l*32
dst[i+l] := (a[i+31:i] == a[m+31:m]) ? 1 : 0
ENDFOR
dst[i+31:i+j] := 0
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
