--- 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?
