I suggest to fix expression weaknesses and a design mistake in this SmPL approach. I guess that you want to determine functions with a signed return type first before corresponding variable assignments will be checked further. * Would you like to collect function names for this purpose by a general analysis of more source files? (How do you think about to store them in a dedicated database?) * Which couple of function calls will be interesting for you? * Should the search approach take also recursively included files into account?
