Any tool to log the execution path of a program?

Question

Is there any tool to log the execution path of functions that a program goes through? I know gdb can show the backtrace at a particular point. But I want to see the whole story of a program. For instance:

int main(){
    a();
    b();
}
void a(){
    c();
}

The tool gives out something like:

a-----
  c------
b------

Answer 1

gcc itself can do it.
