Synopsis
_mm512_mask_abs_pd(__m512d src, __mmask8 k, __m512d v2);
Description
Finds the absolute value of each packed double-precision (64-bit) floating-point element in "v2", storing 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 7
i := j*64
IF k[j]
dst[i+63:i] := ABS(v2[i+63:i])
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:512] := 0
