--- Comment #17 from Jeffrey A. Law <law at redhat dot com> --- So would it work (and I realize this is a horrid hack) to have a way for the backend to set the pic-pseudo as live at the key points during IRA? It'll be overly conservative, but it may still be better than going back to a fixed PIC register. If we had the conservative live information during IRA, presumably it would flow through to LRA and avoid this problem?
