Release aarch64 artifacts for LLVM14 (LLVM-173)

[kevin-june]

The LLVM13 release contains artifacts for:

• aarch64-apple-darwin
• aarch64-unknown-linux-gnu

We would like to use similar artifacts in LLVM 14, but these don't seem to be present.

Is it possible to add these to the release?

Hi @kevin-june,
The artifacts for aarch64 have been built for LLVM13 release manually by the esp-rs team. For LLVM14 the archives have also been built manually and uploaded to https://github.com/esp-rs/rust-build/releases/tag/llvm-project-14.0-minified instead, to avoid confusion.

We have recently merged support for building aarch64-unknown-linux-gnu releases in CI, and CI builds for aarch64-apple-darwin are in development. So the next llvm-project release should have archives for aarch64 built. For now, please try to use the archives provided in the rust-build repo.

@kevin-june @igrr FYI. The artifacts in esp-rs are stripped version of the release which include libraries and headers only used by Rust.

Thanks for the info!

Will the future release include standard library headers? We had been using these to satisfy Bindgen.

Are you talking about special stripped (minified) releases for Rust?
What standard library do you mean, stdc++?

@kevin-june We made a pre-release with ARM64 artifacts https://github.com/espressif/llvm-project/releases/tag/esp-15.0.0-20220922

Thanks!

We primarily use C headers.
