Remove support for compiler plugins.

2023-11-03T21:50:46+00:00

They've been deprecated for four years. This commit includes the following changes. - It eliminates the `rustc_plugin_impl` crate. - It changes the language used for lints in `compiler/rustc_driver_impl/src/lib.rs` and `compiler/rustc_lint/src/context.rs`. External lints are now called "loaded" lints, rather than "plugins" to avoid confusion with the old plugins. This only has a tiny effect on the output of `-W help`. - E0457 and E0498 are no longer used. - E0463 is narrowed, now only relating to unfound crates, not plugins. - The `plugin` feature was moved from "active" to "removed". - It removes the entire plugins chapter from the unstable book. - It removes quite a few tests, mostly all of those in `tests/ui-fulldeps/plugin/`. Closes #29597.

Clean up `rustc_*/Cargo.toml`.

- Sort dependencies and features sections. - Add `tidy` markers to the sorted sections so they stay sorted. - Remove empty `[lib`] sections. - Remove "See more keys..." comments. Excluded files: - rustc_codegen_{cranelift,gcc}, because they're external. - rustc_lexer, because it has external use. - stable_mir, because it has external use.

Add `rustc_fluent_macro` to decouple fluent from `rustc_macros`

2023-04-18T18:56:22+00:00

Fluent, with all the icu4x it brings in, takes quite some time to compile. `fluent_messages!` is only needed in further downstream rustc crates, but is blocking more upstream crates like `rustc_index`. By splitting it out, we allow `rustc_macros` to be compiled earlier, which speeds up `x check compiler` by about 5 seconds (and even more after the needless dependency on `serde_json` is removed from `rustc_data_structures`).

expand: Pass `ast::Crate` by reference to AST transforming passes

Also some more attributes are passed by reference.

Simplify message paths

2023-03-11T21:51:57+00:00

This makes it easier to open the messages file while developing on features. The commit was the result of automatted changes: for p in compiler/rustc_*; do mv $p/locales/en-US.ftl $p/messages.ftl; rmdir $p/locales; done for p in compiler/rustc_*; do sed -i "s#\.\./locales/en-US.ftl#../messages.ftl#" $p/src/lib.rs; done

errors: generate typed identifiers in each crate

2023-02-22T09:15:53+00:00

Instead of loading the Fluent resources for every crate in `rustc_error_messages`, each crate generates typed identifiers for its own diagnostics and creates a static which are pulled together in the `rustc_driver` crate and provided to the diagnostic emitter. Signed-off-by: David Wood
