VEXPANDPD xmm {k}, m128
Synopsis
_mm_mask_expandloadu_pd(__m128d src, __mmask8 k, void const* mem_addr);
Description
Load contiguous active double-precision (64-bit) floating-point elements from unaligned memory at "mem_addr" (those with their respective bit set in mask "k"), and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
m := 0
FOR j := 0 to 1
i := j*64
IF k[j]
dst[i+63:i] := MEM[mem_addr+m+63:mem_addr+m]
m := m + 64
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:128] := 0
