PR 138515, we insert a placeholder attribute so that checks for attributes can still know about the placement of `cfg` attributes. When we suggest removing items with `cfg_attr`s (fix Issue 56328) and make them verbose. We tweak the wording of the existing "unused `extern crate`" lint. ``` warning: unused extern crate --> $DIR/removing-extern-crate.rs:9:1 | LL | extern crate removing_extern_crate as foo; | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ unused | note: the lint level is defined here --> $DIR/removing-extern-crate.rs:6:9 | LL | #![warn(rust_2018_idioms)] | ^^^^^^^^^^^^^^^^ = note: `#[warn(unused_extern_crates)]` implied by `#[warn(rust_2018_idioms)]` help: remove the unused `extern crate` | LL - #[cfg_attr(test, macro_use)] LL - extern crate removing_extern_crate as foo; LL + | ```
