Bug #: 50689 Summary: AIX bootstrap failure from cgraphunit.c aliases change Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap AssignedTo: unassig...@gcc.gnu.org ReportedBy: d...@gcc.gnu.org Created attachment 25454 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25454 Pre-processed file that is miscompiled The patch to cgraphunit.c forcing aliases to be output when cgraph decides so causes an AIX bootstrap failure. The patch shifts the output of the aliases in the assembly file to earlier in the file, before the definition. AIX assembler is a single pass assembler and does not allow forward references.
