--- Comment #12 from Alan Modra <amodra at gmail dot com> --- Created attachment 37857 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37857&action=edit workaround patch Given the problems identified with notes (and of course the notes are what drives reg_equiv_init passed on to reload), one simple fix is to run delete_trivially_dead_insns early in ira. I've left the later call in, but that might be better moved into the optimize && rebuild_p block.
