C++ function call routes resolver

Question

Hi!

I'm looking for a tool that will tell/resolve for every function all the call paths (call it "routes") to it.

For example:

void deeper(int *pNumber)
{
 *pNumber++;
}
void gateA(int *pNumber)
{
 deeper(pNumber);
}
void gateB(int *pNumber)
{
 gateA(pNumber);
}

void main()
{
 int x = 123;
 gateA(&x);
 gateB(&x);
}

See? I need a tool that will tell me all the routes to deeper(), and more if possible.

By saying "more" I mean that it will tell me if the pointer is the same as been provided to the calling function.

This will greatly save me time. Thanks!

Answer 1

Doxygen will do that for you. It'll draw you nice inheritance trees and show you everyone who is calling (and called by) your functions.

Answer 2

I think cppDepend has that functionality (along with other code analysis features)

Answer 3

you can look at the clang analyzer.

The Clang Static Analyzer is source code analysis tool that find bugs in C/C++ and Objective-C programs.

I didn't tried it but looking at the screenshots of code review, it might be usefull
