--- Comment #13 from Steven Bosscher <steven at gcc dot gnu.org> 2010-12-18 19:21:05 UTC --- I'd like to wait for Honza's opinion before we just start trying random patches. But if you feel like trying some other things, perhaps you can see if backporting all changes of http://gcc.gnu.org/viewcvs?view=revision&revision=166517 helps.
