1 Consider this program:
|
|
|
2
|
|
|
3 $ cat a.c
|
|
|
4 void g(int x) {}
|
|
|
5 void f(int x);
|
|
|
6 int main(int argc) {
|
|
|
7 if (argc) {
|
|
|
8 int x = 42;
|
|
|
9 f(x);
|
|
|
10 } else {
|
|
|
11 int y = 13;
|
|
|
12 f(y);
|
|
|
13 }
|
|
|
14 }
|
|
|
15
|
|
|
16 $ cat b.c
|
|
|
17 extern void g();
|
|
|
18 void f(int x) {
|
|
|
19 if (x) {
|
|
|
20 int y = x + 3;
|
|
|
21 g(y);
|
|
|
22 } else {
|
|
|
23 int w = x + 4;
|
|
|
24 g(w);
|
|
|
25 }
|
|
|
26 }
|
|
|
27
|
|
|
28 This program is interesting because there are two TUs, and each TU has nested
|
|
|
29 scopes. Make sure we get the right parent and end offsets.
