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 | ||

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. | |
