Synopsis
_mm512_mask_recip_pd(__m512d src, __mmask8 k, __m512d a);
Description
Computes the reciprocal of packed double-precision (64-bit) floating-point elements in "a", 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] := (1.0 / a[i+63:i])
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:512] := 0
