The proper solution is to fix the assembler, but in the meantime,
the mr and rm variants at least should be changed to movq.  They
are broken on MacOS X right now anyway.  From what you've said,
one can't do a 32-bit memory mov to/from an xmm on MacOS X.
You still won't be able to do a 32-bit memory operation but at least
systems that use the latest binutils will work properly.
