Should this be right after register allocation? Any reason to
keep the pseudo instructions around after allocation?
It should probably be after prolog/epilog insertion. As for the
post RA scheduler and branch folding, I'd think it'd be OK to put
it before them. Thoughts?
Not sure. Why do you think it's necessary for it to be after PEI?
Now that I think on it, I don't think moving it before PEI would
preclude any future operations.
It should definitely be run before post-ra scheduler,IMHO.
Sure. Easy change.
