             Bug #: 57118
           Summary: g++.dg/debug/* tests fail on MIPS due to micromips
                    checkin, scan-assembler pattern needs update
    Classification: Unclassified
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: sje@gcc.gnu.org
                CC: clm@codesourcery.com
            Target: mips*-*-*


The micromips checkin changed the assembler output for MIPS by adding a '.set
nomicromips' psuedo-instruction to the instruction stream.  This is causing the
following tests to fail.  I think the fix is to update the scan pattern for
mips in gcc/testsuite/lib/scanasm.exp.  It looks for mips16/nomips16 but does
not check for micromips/nomicromips.

Tests that fail:
