Graphite calls limit_scops() to ensure, that every SCoP contains a single surrounding loop, as graphite - at the moment - is not able to handle SCoPs with two outermost loops or a bb not contained in any loop.
In theory that is possible without problems, only some little bugs are in the way. So fix the bugs, remove limit_scops() and make theory reality. -- Summary: [graphite] Fix problems with SCoPs, that contain more than one loop Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization AssignedTo: grosser at gcc dot gnu dot org ReportedBy: grosser at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37705
