One other thing: this exercise has shown that in many cases we trash scratch registers in places where it really doesn't matter, and we'd be much better off rewriting them not to do so.
Agreed.
This makes push_call_clobbered_registers() something that can safely be used everywhere. But I'm holding off any of this because I want the first patch to be, if at all possible, neutral with regard to code generated. . . . Yes, that patch is an improvement.
