--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-01-08 15:16:52 UTC --- But then, won't the exact same issues potentially happen in very large functions where ira_conflicts_p isn't also true, because the conflict table would be too big? I'd say zero MB conflict table is reasonable parameter value, it says don't use the conflict table. If table larger than the param would be needed, no table is created at all.
