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