| Consider this program: |
| |
| $ cat a.c |
| void g(int x) {} |
| void f(int x); |
| int main(int argc) { |
| if (argc) { |
| int x = 42; |
| f(x); |
| } else { |
| int y = 13; |
| f(y); |
| } |
| } |
| |
| $ cat b.c |
| extern void g(); |
| void f(int x) { |
| if (x) { |
| int y = x + 3; |
| g(y); |
| } else { |
| int w = x + 4; |
| g(w); |
| } |
| } |
| |
| This program is interesting because there are two TUs, and each TU has nested |
| scopes. Make sure we get the right parent and end offsets. |
