@bors try=dist-aarch64-apple

I hope this will let me then try this commit in Miri's CI (i.e., install it via rustup-toolchain-install-master).

Unknown command "try". Run @bors help to see available commands.

r=me if this unbricks miri's CI

EDIT: ok nvm I saw #152768 (comment), I agree with revert-to-baseline.

CC @ZuseZ4

Revert "Enable autodiff in ci for all major os" Reverts rust-lang#152768 which fixes rust-lang#153077.

ZuseZ4 · 2026-02-25T12:45:04Z

If that's not in the queue yet, can you please only revert the macos commit? I extra had that one split out.

RalfJung · 2026-02-25T12:46:48Z

#153084 already started the build so we'd have to abort the rollup. It wasn't clear whether CI was expected to pass with just that one commit reverted and I didn't want to risk this PR bouncing.

RalfJung · 2026-02-25T12:49:01Z

Oh wait that's just a try build there. Okay then I can update the PR. I hope you're sure that that'll land. :)

`rustc-llvm-proxy` used to work on musl targets by accident because `LD_LIBRARY_PATH` let it `dlopen` our shared LLVM library. After switching to `rpath`, that no longer works: our shared LLVM library is not visible to `rustc-llvm-proxy`, and musl Rust toolchains ship `libLLVM` statically, so there is no shared library for `rustc-llvm-proxy` to load. This caused CI failures such as: unable to read dir /home/runner/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-unknown-linux-musl/lib: No such file or directory (os error 2) thread 'test_link_ir_files' (4) panicked at /rustc/cf7da0b7277cad05b79f91b60c290aa08a17a6f0/library/core/src/panicking.rs:225:5: [...] unable to read dir /home/runner/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib: No such file or directory (os error 2) unable to read dir /root/.cargo/lib: No such file or directory (os error 2) thread 'test_link_ir_files' (4) panicked at /home/runner/work/bpf-linker/bpf-linker/bpf-linker/target/x86_64-unknown-linux-musl/debug/build/aya-rustc-llvm-proxy-5f163ea45ef44b54/out/llvm_gen.rs:14919:10: LLVMParseIRInContext2: DlSym { source: "Symbol not found: LLVMParseIRInContext2" } The behavior on darwin targets is not reliable. Stable Rust toolchains for macOS link `libLLVM` statically. Nightly tried to switch to dynamic linking[0][1], but those attempts were reverted twice[2][3]. Prevent any related issues by excluding `default` and `rust-llvm-*` features on darwin and musl targets.
