That's not part of the llvm project.

It is simply a false impression that code in the middle of being upstreamed is "unused" or "unnecessary". Since it not all of it is upstreamed, changing interfaces and support code in llvm-project directly is going to cause problems that can become hard to track and resolve while the upstreaming is ongoing.

It very much is unused and unnecessary as there are no pieces of that code in the repository.

In general, I'd raise exception with "there are plenty of compilation warnings in LLVM today" as it's just not true - at least not with clang as I run a full build with Werror and fix any that slip in. Happy to have anything you're seeing fixed, but warnings with errors turned on are even on bots. Do you have a bot that shows a warning that's erroring out? This is the only warning that shows up in my full build with clang.

What solution? What compiler is causing issues? If it's a supported compiler I'm happy to help figure it out, but this has been going on for a bit and it's a pair of one line fixes.
