Hello rsc,

I'd like you to review the following change.

LGTM

but add a todo - we should probably
move m and g to make room for memmove's
register block.

will do. memmove can actually be implemented without saving m and g if we use lr
post frame saving. i haven't thought through yet how this would affect tracing
of assembly functions (ie. you can no longer assume lr points to the immediate
frame)
