I guess we should simply not run IPA passes at -O0 (like we do not support enabling random scalar passes at -O0, though in the end I'd like to support that for poor-mans unit-testing). I suppose the IPA fixup pass needs to be run by the pass manager dependent on a property which IPA passes can re-set. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hubicka at gcc dot gnu dot | |org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Keywords| |ice-checking Last reconfirmed|0000-00-00 00:00:00 |2010-04-09 08:46:13 date| | Target Milestone|4.5.0 |4.5.1 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43695 ^ permalink raw reply [flat|nested] 7+ messages in thread
