I have a rather lengthy legacy code function. Is there any way to check if it is using any global variables or disable access to any?

I would check for data symbols in the generated object file:
nm -po file.o | grep ' D 'The compiler generates a couple of symbols and you probably want to check for a couple of other kind of symbols, e.g.Band lowercase versions.
