I am writing a C project. Now I just doubt one function in the whole project may be take the most of computational complexity. If I can make sure about this, I can further improve this function with a more clear target.
Or, is there any tools for this usage?? I mean to find the most “expensive” function in the whole program or project??
Any advices? Thanks!
The gprof profiler comes with the GCC compiler suite. Theres a manual for it here.
