             Bug #: 55145
           Summary: [4.8 Regression] [x32] -maddress-mode=long miscompiles
                    glibc
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hjl.tools@gmail.com

After fixing PR 55142, GCC 4.8 revision 193001 miscompiles
glibc trunk for x32 with -maddress-mode=long.  Most glibc
tests failed with "Segmentation fault".  It is independent
of LRA and may have something to do with recent subreg
changes.
