           Summary: [4.7 regression] bootstrap comparison failures on
                    m68k-linux
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mikpe@it.uu.se


The last 4.7 snapshot I was able to build on m68k-linux was 4.7-20110326. 
Since then, every single weekly snapshot has failed with bootstrap comparison
failures.  Some weeks other archs have also seen bootstrap comparison failures
but recently they aren't, however m68k-linux still does:

I will attempt to bisect this, but with the multiple generic bootstrap
comparison failures 4.7 has experienced recently, it's going to take some time.
