             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: unassig...@gcc.gnu.org

        ReportedBy: hjl.to...@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.
