Bug #: 52781 Summary: duplicate pass names, rtl dce Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: minor Priority: P3 Component: rtl-optimization AssignedTo: unassig...@gcc.gnu.org ReportedBy: m...@gcc.gnu.org The usual convention is to have the stuff after the number in dump file names be unique. Here: -rw-r--r-- 2 mrs users 108734 Mar 29 15:42 t-a.i.178r.dce -rw-r--r-- 1 mrs users 101613 Mar 29 15:42 t-a.i.205r.dce it isn't. There is already a dce1 and a dce2, in the tree passes, so, having the rtl passes either be dce3 and dce4, or dce1 and dce2 would seem to be better.
