How about lifting that limitation? Of course in general, that will only work when there is no recursion. I suggest to use cflow to parse the C code to generate the call graph. You'd probably have to be a bit pessimistic (e.g. f might call g at two sites, and the two sites might be at different stack depth, since on of the two calls might have more registers in use, and thus more push / pop pairs around the actual call).
