The test passes with the build just before that range and fails with r150301, the first revision that builds after a merge from the Graphite branch. -- Summary: failing tree check in graphite-sese-to-poly.c for 164.gzip Product: gcc Version: 4.5.0 Status: UNCONFIRMED Keywords: ice-on-valid-code Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: janis at gcc dot gnu dot org GCC target triplet: powerpc-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42284 ^ permalink raw reply [flat|nested] 8+ messages in thread
