I'm currently working on a large and old C++ application that has had many developers before me. There is a lot of "dead code" in the project, classes and functions that aren't used by anyone anymore.
What tools are available for C++ to make a analysis of large code base to detect and refactor dead code? Note: I'm not talking about test coverage tool like gcov.
How do you find dead code in your project?
You'll want to use a static analysis tool
The main gotcha I've run into is that you have to be careful that any libraries aren't used from somewhere that you don't control/have. If you delete a function from a class that gets used by referencing a library in your project you can break something that you didn't know used the code.
