[PATCH] D63863: [ARM] Make coprocessor number restrictions consistent.

[Simon Tatham via Phabricator via llvm-commits]

simon_tatham added a comment.

So it sounds as if the most immediate problem is that there now _isn't_ an architecture you can specify on clang's command line that permits the union of all the instructions you plan to use?

Would some kind of architectural extension be a reasonable solution? `-march=armv8+oldcoprocessors`, or some such? That way `-march=armv8` continues to diagnose things that actually are illegal in the architecture you asked for.
