…ebank overhaul unused doc comments lint This PR contains a number of improvements to the `unused_doc_comments` lint. - Extends the span to cover the entire comment when using sugared doc comments. - Triggers the lint for all unused doc comments on a node, instead of just the first one. - Triggers the lint on macro expansions, and provides a help note explaining that doc comments must be expanded by the macro. - Adds a label pointing at the node that cannot be documented. Furthermore, this PR fixes any instances in rustc where a macro expansion was erroneously documented.

allow specifying attributes for tool lints Needed for clippy to fix `unused_doc_comments` warnings that will be exposed by rust-lang#57882 (and thus unblock it).

move lint documentation into macro invocations This PR moves lint documentation inside `declare_clippy_lint!` macro invocations, to avoid triggering the `unused_doc_comments` lint once it's modified in rust-lang/rust#57882. This PR is necessary to unblock that work, since the large number of warnings generated in `clippy_lints` causes Travis to hit the log length limit. This PR also updates the documentation and website generation script. It would be nice to get a clippy update in the Rust repo once this is merged. cc @phansch

@euclio The Clippy submodule should now contain the changes to make this pass. |
Report all unused attributes on a given doc comment instead of just the first one, and extend the span of sugared doc comments to encompass the whole comment.
Report the diagnostic on macro expansions, and add a label indicating why the comment is unused.

Clarify unused_doc_comments note on macro invocations The previous error message used to say: <pre> /// doc ^^^^^^^ rustdoc does not generate documentation for <b>macros</b> </pre> Obviously we do generate documentation for macros, such as https://docs.rs/bitflags/1.2.1/bitflags/macro.bitflags.html. It's only macro invocations that don't get their own docs. This PR updates the message to say "rustdoc does not generate documentation for <b>macro invocations</b>". I observe that prior to rust-lang#69084 this used to say "rustdoc does not generate documentation for **macro expansions**", as implemented originally in rust-lang#57882. I don't have a preference between those but I made the commit before looking up the history. r? @Manishearth attn: @yaahc @euclio
