--- Comment #2 from Drea Pinski <pinskia at gcc dot gnu.org> --- Created attachment 65422 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=65422&action=edit Slightly reduced Added debug printfs. note the commented out ones seems to break the loop too. Note also ao, al and ap can't be marked as noipa because IPA modref needs to know they don't clobber some references it seems.
