Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Attachment #29369|0 |1 is obsolete| | --- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> 2013-02-06 15:54:43 UTC --- Created attachment 29371 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29371 final patch This is what I am considering seriously. It adds the dumping (but we don't have info on the BB index of removed loops - bah), and also moves loop removal to fix_loop_structure again. It doesn't fix IRAs (pre-existing) ugliness. The previous patch passed bootstrap, I'm giving this one full testing (it co-incidentially fixes the bug as well).
