[PATCH] D154691: [RISCV] Implement prefetch locality by NTLH

[Alex Bradbury via Phabricator via llvm-commits]

asb added a comment.

I just mentioned this in https://github.com/riscv-non-isa/riscv-c-api-doc/pull/46, but given the NTL instructions are all just hints, perhaps we should be unconditionally emitting them even if zihintntl isn't known to be present (though printing it as `add x0, x0, x?` in .s form in that case). Not a blocker for landing this patch, but thought I'd mention.
