Well, presumably if you are copying values in and out of registers, it is preferable to use 64 bit registers, thereby shifting around 64 bits at a time. If that seems underwhelming, well, that might explain Solaris... -- If this was helpful, <http://svcs.affero.net/rm.php?r=cbbrowne> rate me http://www.ntlug.org/~cbbrowne/emacs.html "[In 'Doctor' mode], I spent a good ten minutes telling Emacs what I thought of it.
