--- Comment #9 from Jeffrey A. Law <law at gcc dot gnu.org> --- Right. It's fairly common with fold-mem-offsets to end up rewriting the address arithmetic such that we'll have an sp->gpr copy of some sort in the IL. We'd really like to be able to cprop that copy away. After Manolis's fixes to that code it seemed independently commit-able so I acked it while we iterate on the fold-mem-offsets work. It's tickled a few problems, but nothing that seems unmanageable right now.
