If it makes sense to inline the local calls (ie the cost
of the call is significant) then possibly add an inlined
(or inlinable) static function that is called locally and
by the exported one?

I'm not sure that gcc is allowed to make the assumption
that the local exported function will be called - and
thus inline it.
