Unfortunately, my current patch foregos step four from resolve_branch, which is necessary to establish validity of the source program, and at the moment I have no convincong idea on how to implement this in the framework with bitmaps. I hope I can attend to this soon, thus re-assigning to myself. -- tobi at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |tobi at gcc dot gnu dot org |dot org | Status|NEW |ASSIGNED Last reconfirmed|2006-01-14 19:03:18 |2007-03-23 22:27:07 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18937
