--- Comment #45 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-02-03 13:19:29 UTC --- Created attachment 23235 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23235 gcc46-pr23200-1.patch So, if we want to make this work just with -ftree-ter, we could do something like the attached patch. At least currently we don't emit column info for code in any kind of supported debug info format, so we could do it this way.
