--- Comment #12 from Jan Hubicka <hubicka at gcc dot gnu.org> 2012-11-05 16:24:07 UTC --- Yeah + there is quite nice code size savings. I must say it took quite a while to chase out all bugs that was affecting tramp3d's performance. One thing I noticed however is that our EH tables are several times bigger than clang's that probably counts as a bug. I will open separate PR for that. At quick glance all throwing calls seems quite resonable to me. Honza
