So a conservative fix for 4.2 is to just not record symbolic equivalencies at all. I wonder if there is a better way to deal with these issues than fix_equivalence_set though. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dnovillo at redhat dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29446
