             Bug #: 56858
           Summary: alpha looks for NOTE_INSN_EH_REGION notes that cannot
                    exist
    Classification: Unclassified
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: steven@gcc.gnu.org


Via alpha.c:alpha_handle_trap_shadows(), the alpha_reorg pass
looks for NOTE_INSN_EH_REGION_BEG and NOTE_INSN_EH_REGION_END
notes. But those notes are created much later, and can never
exist in the machine-dependent reorg pass.
