rust-embedded.github.io Outdated answer of the question "(When) will Rust support the Xtensa architecture?"

The LLVM dashboard is an invalid link. I can't find the successor of this "dashboard", but https://discourse.llvm.org/search?q=xtensa%20order%3Alatest can be checked.

The original LLVM does support the xtensa for now:

Thanks! Could you submit a PR updating that?

No, thanks. I am not good at writing documentation.

Note: The ESP fork of the Rust toolchain has just updated to version 1.85, upgrading to LLVM ESP fork version 19 (https://github.com/esp-rs/esp-hal/issues/3146). Currently the official LLVM doesn't really support the Xtensa target, but there's some ongoing pull request(s): https://github.com/espressif/llvm-project/issues/4 (I'm not sure if this will resolve the esp-hal Wifi speed issue with the Xtensa target: https://github.com/esp-rs/esp-hal/issues/1605)
