I do quite like the idea of a whole set of aarch64-cortex-<foo>.c files, for the same reason I mentioned in D120875: it means that when someone is implementing support for the next CPU, they'll look at the existing test collection and naturally add a new file alongside all the others, instead of naturally appending another stanza to this file which will eventually grow too big again.

But like the previous patch, I won't block you making this much improvement just because you haven't made even more improvement :-)
