Well, it is really some form of IPA driven register allocation. Whether
you want to call it -fipa-ra or not is another question - but if we had
such option then enabling it with that option would be fine.
Also users may have no idea what call vs callee clobbers are, but
IPA RA may be a term that is more widely known (or at least google
can come up with something for you).
So - I like -fipa-ra more.
Similarly. At the heart of the matter is we're utilizing information
about the callee's behaviour to improve the code we generate in the
caller. That's clearly in IPA's domain IMHO.
