resolve rustdoc incompatibility with `rust.download-rustc=true` + `rust.channel= beta/stable` Previously, we were unable to use `rust.download-rustc` with the beta or stable channel settings through `rust.channel` due to breaking rustdoc UI tests. This was because when using a precompiled nightly compiler from CI, we must use the channel of precompiled compiler and ignore `rust.channel` from the configuration. This change addresses that issue in `Builder::doc_rust_lang_org_channel` and allows rustdoc UI tests to work with the precompiled compiler even if the channel specified in config.toml is "beta" or "stable". Blocker for https://github.com/rust-lang/rust/pull/122709
This directory contains some source code for the Rust project, including:
- The bootstrapping build system
- Various submodules for tools, like cargo, tidy, etc.
For more information on how various parts of the compiler work, see the rustc dev guide.
