To transfer a 64 bit number in edx:eax to mm0

movd mm0, edx
movd mm1, eax
psllq mm0, 32
por mm0, mm1


movd mm0, eax
movd mm1, edx
punpckldq mm0, mm1

Is this useful?

The later is preferable, shifts don't pair on P1/2/3, iirc.

I wrote the former several months ago, before I joined the forum.

The latter I just derived from PD code from Eric Goldstein's...
