If a compare operation, but no branch exists, the cbranch handler is not used. If no compare operation exists, we can't generate compare / setcc sequences. cstore patterns are recognized by genopinit, but cause a compiler crash their presence influences code generation. -- Summary: impossible to both expand store flag operations and use a cbranch handler Product: gcc Version: 4.3.0 Status: UNCONFIRMED Keywords: ice-on-valid-code, missed-optimization Severity: normal Priority: P3 Component: middle-end AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: amylaar at gcc dot gnu dot org OtherBugsDependingO 29842,29845 nThis: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29846
