           Summary: FAIL: g++.dg/debug/dwarf2/cdtor-1.C
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
        AssignedTo: unassig...@gcc.gnu.org

Since revision 174497 the we have the following failure on *-apple-darwin*

FAIL: g++.dg/debug/dwarf2/cdtor-1.C scan-assembler-times
[^\\n\\r]*DW_AT_MIPS_linkage_name: 2

Revision 174466 is OK (see
http://gcc.gnu.org/ml/gcc-testresults/2011-05/msg03636.html ). AFAICT the test
has never passed on darwin since its introduction at revision 174474. Grepping
the assembler for DW_AT_MIPS_linkage_name I get

[macbook] f90/bug% grep DW_AT_MIPS_linkage_name cdtor-1.s
    .ascii "_ZN1KC1Ev\0"    # DW_AT_MIPS_linkage_name
    .ascii "_ZN1KD1Ev\0"    # DW_AT_MIPS_linkage_name
    .byte    0x87,0x40    # uleb128 0x2007; (DW_AT_MIPS_linkage_name)

The following patch fixes the test on darwin
