How about something simple like:
if (SMALL_REGISTER_SET) never_inline_functions_unless_the_user_asked_for_it();
which means that even with -O6 you would not inline functions unless they were marked inline.
Note that this is not just a workaround for a bug. The fact is, that with small-register-set, inlining functions is not likely to be all that big of a win (and is often a loss due to register allocation pressure) unless the function is _really_ small or for some special cases - and in both cases hopefully the function is marked inline already by the knowledgeable user.
