[PATCH] D89288: [RISCV] Enable the use of the old sptbr name

[Sam Elliott via Phabricator via llvm-commits]

lenary added a comment.

I think supporting the old CSR names is a small, simple thing that we can do which removes a barrier to people moving to using LLVM rather than GCC. Better this than death by a thousand cuts when people try to move their software over. Yes, people *should* just update their software (and dependencies). The question is will they?

Yes, I do think at some point we need a more principled approach to CSR naming support, but in the short term, doing so in an ad-hoc manner is fine. I think some kind of warning is a good idea, but LLVM's architecture may not be well set up for that, in all honesty.
