Synopsis
_mm512_mask_mul_pd(__m512d src, __mmask8 k, __m512d a, __m512d b);
Description
Multiply packed double-precision (64-bit) floating-point elements in "a" and "b", and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set). RM.
Operation
FOR j := 0 to 7
i := j*64
IF k[j]
dst[i+63:i] := a[i+63:i] * b[i+63:i]
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:512] := 0
