Synopsis
_mm512_mask_mullox_epi64(__m512i src, __mmask8 k, __m512i a, __m512i b);
Description
Multiplies elements in packed 64-bit integer vectors "a" and "b" together, storing the lower 64 bits of the result 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] := a[i+63:i] * b[i+63:i]
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:512] := 0
