           Summary: SPECint2006 403.gcc fails with -mzarch -m31
           Product: gcc
           Version: 4.5.3
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: rtl-optimization
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: kreb...@gcc.gnu.org


The 403.gcc testcase throws an ICE when compiled with -m31 -mzarch. The seems
to be that IRA does not handle HARD_REGNO_CALL_PART_CLOBBERED properly.

Fix proposal:
