⌛ Trying commit 927ee0620ed011e284a915d358d160315217ec1f with merge d8b81c884750a4b6d7fb3ee3f8a1f646ad24c982...

Changes look good by the way!

Or they would if I knew how booleans worked 🤦‍♂️

☀️ Try build successful - checks-actions, checks-azure
Build commit: 462ec6baef52edea591eab1a070ed4e18b80d094 (462ec6baef52edea591eab1a070ed4e18b80d094)

[shepmaster]

Ok, with that try build I can do something like

% rustup-toolchain-install-master --force 462ec6baef52edea591eab1a070ed4e18b80d094 --targets aarch64-apple-darwin

% SDKROOT=$(xcrun -sdk macosx11.0 --show-sdk-path) MACOSX_DEPLOYMENT_TARGET=$(xcrun -sdk macosx11.0 --show-sdk-platform-version) cargo +462ec6baef52edea591eab1a070ed4e18b80d094 build --target=aarch64-apple-darwin

And cross-compile easily. Now we just need to wait for Mark-Simulacrum's PRs to get merged and I'll rebase and move the changes to their own regular builders.

This has happened.

I'll rebase and move the changes to their own regular builders.

As has this.

This PR is promoting the aarch64-apple-darwin target from Tier 3 to a Tier 2 development platform:

• For infrastructure approval I'd say it doesn't need consensus from the whole team, as we definitely have capacity for a standard sized builder (we don't have XL macOS builders).
• For compiler team approval, I'm nominating this PR.

@rustbot modify labels: T-compiler I-nominated

[emilyalbini]

This PR also needs to update src/doc/rustc/src/platform-support.md.

What's missing to have the rust-std artifacts available to rustup target add? (it's currently saying the toolchain doesn't contain component 'rust-std' for target 'aarch64-apple-darwin' on the nightly off 8dae8cd which is after this was merged)

As for most everything else for this project, the details have been discussed on Zulip.
