Synopsis
_mm512_mask_sub_epi32(__m512i src, __mmask16 k, __m512i a, __m512i b);
Description
Subtract packed 32-bit integers in "b" from packed 32-bit integers in "a", and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
i := j*32
IF k[j]
dst[i+31:i] := a[i+31:i] - b[i+31:i]
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
