Steven Bosscher <steven at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |WAITING --- Comment #21 from Steven Bosscher <steven at gcc dot gnu.org> 2012-07-30 09:11:27 UTC --- Markus, I think that r189951 should have fixed this problem (xf. http://gcc.gnu.org/viewcvs?view=revision&revision=189951), although I suspect there will still be a compile time increase from GCC 4.7 to GCC 4.8 because of the macro expansion tracking stuff. Could you please try a recent trunk GCC 4.8 and report back how compile times look for you now?
