| |
| ### Others |
| |
| * Introduce a `--rustc` flag to `clippy-driver`, which turns `clippy-driver` |
| into `rustc` and passes all the given arguments to `rustc`. This is especially |
| useful for tools that need the `rustc` version Clippy was compiled with, |
| instead of the Clippy version. E.g. `clippy-driver --rustc --version` will |
| print the output of `rustc --version`. |
| [#5178](https://github.com/rust-lang/rust-clippy/pull/5178) |

| or not annoying enough! [#5735](https://github.com/rust-lang/rust-clippy/pull/5735) |
