--- Comment #2 from ktkachov at gcc dot gnu.org ---
In the Arm architecture this is FEAT_LRCPC2. LLVM does have an MC (essentially
assembler-level) feature string for it called "rcpc-immo", so if we wanted to
support this I guess we'd want to be compatible.
That said, it may be cleaner to just remove support for thunderx3t110 if we
think it's the right time.
Unfortunately we do still have some cases where our features aren't
fine-grained enough and are tied to architecture levels that some CPUs don't
claim to support:
