Instruction
VDIVPD xmm {k}, xmm, xmm
Synopsis
_mm_mask_div_pd(__m128d src, __mmask8 k, __m128d a, __m128d b);
Description
Divide packed double-precision (64-bit) floating-point elements in "a" by packed elements in "b", 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 1
i := 64*j
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:128] := 0
