Add a few more possibly false-positive tests for the `improper_ctypes` lint
It caused a test regression in the `cfg_eval.rs` crate. (The bugfix in rust-lang#129346 was in a different commit; this commit was just a code simplification.)
The previous version used `['l', 'l']` as pattern, which would suggest that it matches the `ll` of `Hello world` as a whole.
…ler-errors Improve duplicate derive Copy/Clone diagnostics Improve duplicate derive Copy/Clone diagnostics. Closes rust-lang#131083
fix suggestion for diagnostic error E0027 Closes rust-lang#132008
…ler-errors More tests for non-exhaustive C-like enums in FFI Add a few more tests for the `improper_ctypes` lint as found with the [varnish-rs](https://github.com/gquintard/varnish-rs) project. This follows up on rust-lang#116831, fixed in rust-lang#116863 by ``@workingjubilee`` - I have been seeing these fail with the bindgen-generated non-exhaustive enums inside other structs. Seems the issue does not exist in the primary branch, so this PR just makes sure more cases are covered for the future.
…ler-errors remove support for extern-block const intrinsics This converts all const-callable intrinsics into the "new" form of a regular `fn` with `#[rustc_intrinsic]` attribute. That simplifies some of the logic since those functions can be marked `const fn` like regular functions, so intrinsics no longer need a special case to be considered const-callable at all. I also added a new attribute `#[rustc_const_stable_intrinsic]` to mark an intrinsic as being ready to be exposed on stable. Previously we used the `#[rustc_const_stable_indirect]` attribute for that, but that attribute had a dual role -- when used on a regular function, it is an entirely safe marker to make this function part of recursive const stability, but on an intrinsic it is a trusted marker requiring special care. It's not great for the same attribute to be sometimes fully checked and safe, and sometimes trusted and requiring special care, so I split this into two attributes. This also fixes rust-lang#122652 by accepting intrinsics as const-stable if they have a fallback body that is recursively const-stable. The library changes are best reviewed with whitespace hidden. r? `@compiler-errors`
…placement-ranges, r=petrochenkov Revert "Avoid nested replacement ranges" from rust-lang#129346. It caused a test regression in the `cfg_eval.rs` crate. (The bugfix in rust-lang#129346 was in a different commit; this commit was just a code simplification.) r? `@petrochenkov`
…triddle [rustdoc] Fix `--show-coverage` when JSON output format is used I realized while looking on the docs.rs page of the `sysinfo` crate that the coverage numbers displayed were wrong:  I realized that it was because `--show-coverage --output-format=json` was relying on the same logic as the JSON output for the doc generation whereas it should not. I fixed it by changing the API for querying `is_json` a bit. The underlying issue is that JSON output format is stripping reexports of items from private modules. r? ``@notriddle``
…r=xFrednet Clippy: Move some attribute lints to be early pass (post expansion) r? ```@xFrednet``` As a side effect it removes a duplicated warning on line 53 of the `allow_attributes` test. I discussed this with ```@xFrednet``` , and it's mainly to support the attribute rework rust-lang#131229

It's not obvious to me which PR might be the culprit here and the regression is small and contained enough that I don't think it's worth investigating. @rustbot label: +perf-regression-triaged |
