Code-size wise, an huge improvement to this port would be an option to use an overlayed local variable allocator, just like the 8051 one, because at the moment, the pic16 port uses a full stack based code generator, which is rather inefficient (and very few functions really need reentrancy).

But I have no time to code it, and I know it's a complex matter :(

So that's just a "nice to have" item for a todo list.
