             Bug #: 50857
           Summary: [4.7 Regression] The compiler is built with exceptions
                    and RTTI enabled
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rguenth@gcc.gnu.org

We fail to pass -fno-exceptions -fno-rtti to g++ for stage2 and stage3 building
the host binaries.  That leads to increased compile-time and possibly runtime.

Ian, does Go need exceptions or RTTI?

Any idea where to best fix this?
