Copy stage0 `rustc` binaries to `stage0-sysroot` This is basically a revival of https://github.com/rust-lang/rust/pull/101711 and https://github.com/rust-lang/rust/pull/107956, with an added check that the full sysroot will only be created if the original rustc comes from `stage0/bin`. What is/should be tested: - [x] `rustup toolchain link stage0` (new libstd is used correctly) - [x] `python3 x.py fmt dist --stage 0` - [x] Custom rustc/cargo in `config.toml` (in this case this logic is ignored) - [x] Perfbot (try perf run has succeeded) - [x] Real use case (https://github.com/rust-lang/backtrace-rs/pull/542) (Hopefully) fixes: https://github.com/rust-lang/rust/issues/101691 This is not the "end all, be all" solution to this problem, but as long as it resolves the basic use-case, and doesn't break perfbot, I say ship it. This code will probably be nuked anyway Soon™ because of the stage redesign.
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.
