I'm trying to remove functions that are not used from a C++ project. Over time it's become bloated and I'm looking to remove functions that aren't used at all.
I have all the projects in a solution file in Visual Studio, but I use cmake so I can generate project files for another IDE if necessary (which is why this isn't tagged with visual-studio).
Does something like this exist? Where it'll analyze the source and tell me which functions are not called. I saw PC-Lint mentioned in a few questions here, but that doesn't seem to do this.
What I really want to do is call "Find all references" on each function and remove the functions not called, but doing this manually would take much too long.

Every C program has a primary (main) function that must be named main. If your code adheres to the Unicode programming model, you can use the wide-character version of main, wmain. The main function serves as the starting point for program execution.
A function consist of two parts: Declaration: the function's name, return type, and parameters (if any) Definition: the body of the function (code to be executed)
The _start Function. For most C and C++ programs, the true entry point is not main , it's the _start function. This function initializes the program runtime and invokes the program's main function. The use of _start is merely a general convention.
Use __declspec(deprecated) in front of the function declaration you want to get rid of. That will throw up compile warnings if that function is actually used at compile time.
