VPEXPANDQ xmm {k}, m64
Synopsis
_mm_mask_expandloadu_epi64(__m128i src, __mmask8 k, void const* mem_addr);
Description
Load contiguous active 64-bit integers 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

dst[MAX:128] := 0
