rustc: Move `features` from `Session` to `GlobalCtxt` Removes one more piece of mutable state. Follow up to #114622. The rule I used for passing feature in function signatures: - if a crate already depends on `rustc_middle`, then `Session` is replaced with `TyCtxt` - otherwise session and features are passed as a pair `sess: &Session, features: &Features` The code in `rustc_lint` is ultimately used for implementing a trait from `rustc_expand`, so it also doesn't use tcx despite the dependency on `rustc_middle`.
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.
