Local registers don't increase the amount of available memory they just make a different use of it. When these functions are nested or even used recursively we'll need a considerable amount of additional memory without any benefit. We might use a flag to indicate that it's a nested call and spare the stack saving then. Is it worth the hassle? I doubt it.
