Are there any new requirements regarding LLVM 12 plus? I think it would make sense to also update LLVM at the same time.

I'm not sure, I have not looked at it. I rebased the patches and waited for errors to pop up. Rust claims it needs LLVM 12, so that's next to try!
Another observation. I tried LLVM 14.0.5 and 12.0.1, and both require CMake 3.13.4 or later.
Seems like https://github.com/sailfishos/cmake has the right version, so I'll retry with a more up-to-date sdk.
FWIW, using https://github.com/sailfishos/llvm/pull/1 I have a working Rust compile that can compile Whisperfish. I'll start dog feeding this compiler while I finish https://github.com/sailfishos/llvm/pull/1: clang
still needs some massaging.
The Aarch compiler seems a bit broken on certain crates. Excerpt:

I might need to patch rustc
in here to just turn the outline-atomics
off, because disabling it with RUSTFLAGS as per the internet seems not to work.
This should be fixed whenever Sailfish OS gets gcc 9.3.1 or higher.
I managed to get rust aarch64 compiler to work so I will be probably making a new PR later where I will try to update to even newer rust.
Changes merged in https://github.com/sailfishos/rust/pull/18. Closing this PR.
