             Bug #: 52163
           Summary: [4.7 regression] 64bit powerpc libgcc is missing
                    exported symbols
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: doko@gcc.gnu.org


a 20120205 trunk build on powerpc-linux-gnu, configured with
      --enable-targets=powerpc-linux,powerpc64-linux
     --with-cpu=default32
is missing some exported symbols in the 64bit libgcc_s.so.  The 32bit libgcc
looks fine.
I don't see the missing symbols with 20120121, but 20120129.

I'll do the next test build with r183491 reverted.
