--- Comment #6 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- Can this be re-checked now that the forward threader has been dropped post-VRP? BTW, please CC me on any compile-time hogs related to the threader, especially if it's not SPEC related, as I've yet to hunt down a copy. So far this is the only non-duplicate PR I'm CC'ed on with the threader as a suspect in compile speed.
