Nightly builds are archived under `https://static.rust-lang.org/dist/{date}/`. This adds a new `alt/` subdirectory containing: * `rustc-nightly-x86_64-apple-darwin.tar.gz` * `rustc-nightly-x86_64-unknown-linux-gnu.tar.gz` * `rustc-nightly-x86_64-pc-windows-msvc.tar.gz` copied from `s3://rust-lang-ci2/rustc-builds-alt/`. These are alternative builds of rustc with LLVM assertions disabled, which reduces testing coverage but improves compiler performance. This adds these resources to those that are considered “stable and public” per https://internals.rust-lang.org/t/public-stable-rust-services/6072. For the latest Nightly they take up 143 MiB. At current S3 pricing, this increases the cost of storing 10 years worth of Nightlies by 14 USD per month. This fixes rust-lang/rust#45334 and will enable Servo’s build system to stop relying on private and ephemeral resources.

Thanks for the PR! We discussed this a week or so ago and just got around to posting thoughts. I think that strategy would obviate the need for this PR, so I'm gonna hold off on this for now. |

Closing in favor of rust-lang/rust#45810. |
