$ cat t5.c
int foo1();
int foo2();
int main() {
  return foo1() + foo2();
}
mrs $ clang -cc1 -analyze -cfg-dump -fexceptions  t5.c

 [ B4 (ENTRY) ]
    Predecessors (0):
    Successors (1): B3

 [ B1 ]
      1: return [B2.1] + [B3.1];
    Predecessors (1): B2
    Successors (1): B0

 [ B2 ]
      1: foo1()
    Predecessors (1): B3
    Successors (2): B1 B0
