16/* Testcase to exercise the code path in bug 13961 for Fission.
17 http://gcc.gnu.org/wiki/DebugFission
18
19 Compiled from:
20
21 class foo
22 {
23 public:
24 int bar;
25 };
26
27 foo baz;
28
29 int
30 main ()
31 {
32 return 0;
33 }
34
35 And then manually edited to insert the necessary DW_AT_specification
36 entries to trigger the desired code path.
37 There's no real need to make this architecture-specific, so it has been
38 further hand-edited to support that.
