           Summary: [4.6 regression] -flto -flto-partition=none broken for
                    arm-linux-gnueabi
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ramana@gcc.gnu.org
            Target: arm-linux-gnueabi
             Build: x86_64-linux-gnu


While testing another patch for arm-linux-gnueabi and updating to a newer
version of trunk I see the following failures. This wasn't happening in an
earlier version of trunk that I'd been working on earlier.

I'll try bisecting next to find the version that broke but in any case here
goes.
