It was added in ddee45e when SIGPIPE was controlled with an attribute on `fn main()` which meant it could also be combined with `#[rustc_main]`: #[unix_sigpipe = "sig_dfl"] #[rustc_main] fn rustc_main() { It stopped being needed cde0cde when `#[unix_sigpipe = "..."]` was replaced by `-Zon-broken-pipe=...`. And it will not be needed when `-Zon-broken-pipe=...` is replaced by an Externally Implementable Item. Let's remove this test.

rustc book: fix grammar It was added in ddee45e ([here](https://github.com/rust-lang/rust/pull/97802/changes#diff-85dc642a7bdad363a9e37d2491230280fcd977391ba7a242bda2da9ddb55f654) to be specific) when SIGPIPE was controlled with an attribute on `fn main()` which meant it could also be combined with `#[rustc_main]`: #[unix_sigpipe = "sig_dfl"] #[rustc_main] fn rustc_main() { The test stopped being needed in cde0cde when `#[unix_sigpipe = "..."]` was replaced by `-Zon-broken-pipe=...`.

Move issue-12660 to 'ui/cross-crate/ with a descriptive name fixes rust-lang#98342 r? @GuillaumeGomez Renders intra-doc links in the note text of the `#[deprecated]` attribute. It is quite natural to suggest some other function to use there. So e.g. ```rust #[deprecated(since = "0.0.0", note = "use [`std::mem::size_of`] instead")] ``` renders as <img width="431" height="74" alt="Screenshot from 2026-01-06 12-08-21" src="https://github.com/user-attachments/assets/8f608f08-13ee-4bbf-a631-6008058a51e2" />
