What I did was to assign to %o1 like is done with ldstub, so I assume
that will work.  You are right that we had trouble with 'cas' until we
changed the typedef for slock_t from unsigned char to int, so I added
this patch to use 'unsigned char' for sparcv8.

As far as testing, I think we are going to have to wait for someone who
cares about sparcv8 because none of our current Sparc guys are testing
on that.
