This is a breaking change! Malformed should_panic attributes have had the following warning since 2016:
warning: argument must be of the form: `expected = "error message"` --> src/main.rs:5:1 | 5 | #[should_panic(expected = "foo", bar)] | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: errors in this attribute were erroneously allowed and will become a hard error in a future release This PR makes this an error.
As discussed in #142838 (comment), we can make breaking changes as long as we do a crater run. So this PR needs a crater run.

This issue is currently NOT solved by this PR.
We can do this in a future PR or now, but we should decide whether this should be a warning or error:

🎉 Stabilize `build.build-dir`. This config sets the directory where intermediate build artifacts are stored. These artifacts are produced by Cargo and rustc during the build process. End users usually won't need to interact with them, and the layout inside `build-dir` is an implementation detail that may change without notice. ([config doc](https://doc.rust-lang.org/stable/cargo/reference/config.html#buildbuild-dir)) ([build cache doc](https://doc.rust-lang.org/stable/cargo/reference/build-cache.html)) [#​15833](rust-lang/cargo#15833) [#​15840](rust-lang/cargo#15840) - The `--target` flag and the `build.target` configuration can now take literal `"host-tuple"` string, which will internally be substituted by the host machine's target triple. [#​15838](rust-lang/cargo#15838) [#​16003](rust-lang/cargo#16003) [#​16032](rust-lang/cargo#16032) <a id="1.91.0-Rustdoc"></a> ## Rustdoc - [In search results, rank doc aliases lower than non-alias items with the same name](rust-lang/rust#145100) - [Raw pointers now work in type-based search like references](rust-lang/rust#145731). This means you can now search for things like `*const u8 ->`, and additionally functions that take or return raw pointers will now display their signature properly in search results. <a id="1.91.0-Compatibility-Notes"></a> ## Compatibility Notes - [Always require coroutine captures to be drop-live](rust-lang/rust#144156) - [Apple: Always pass SDK root when linking with `cc`, and pass it via `SDKROOT` env var](rust-lang/rust#131477). This should fix linking issues with `rustc` running inside Xcode. Libraries in `/usr/local/lib` may no longer be linked automatically, if you develop or use a crate that relies on this, you should explicitly set `cargo::rustc-link-search=/usr/local/lib` in a `build.rs` script. - [Relaxed bounds in associated type bound position like in `TraitRef<AssocTy: ?Sized>` are now correctly forbidden](rust-lang/rust#135331) - [Add unstable `#[sanitize(xyz = "on|off")]` built-in attribute that shadows procedural macros with the same name](rust-lang/rust#142681) - [Fix the drop checker being more permissive for bindings declared with let-else](rust-lang/rust#143028) - [Be more strict when parsing attributes, erroring on many invalid attributes](rust-lang/rust#144689) - [Error on invalid `#[should_panic]` attributes](rust-lang/rust#143808) - [Error on invalid `#[link]` attributes](rust-lang/rust#143193) - [Mark all deprecation lints in name resolution as deny-by-default and also report in dependencies](rust-lang/rust#143929) - The lint `semicolon_in_expressions_from_macros`, for `macro_rules!` macros in expression position that expand to end in a semicolon (`;`), is now deny-by-default. It was already warn-by-default, and a future compatibility warning (FCW) that warned even in dependencies. This lint will become a hard error in the future. - [Trait impl modifiers (e.g., `unsafe`, `!`, `default`) in inherent impls are no longer syntactically valid](rust-lang/rust#144386) - [Start reporting future breakage for `ill_formed_attribute_input` in dependencies](rust-lang/rust#144544) - [Restrict the scope of temporaries created by the macros `pin!`, `format_args!`, `write!`, and `writeln!` in `if let` scrutinees in Rust Edition 2024.](rust-lang/rust#145342) This applies [Rust Edition 2024's `if let` temporary scope rules](https://doc.rust-lang.org/edition-guide/rust-2024/temporary-if-let-scope.html) to these temporaries, which previously could live past the `if` expression regardless of Edition. - [Invalid numeric literal suffixes in tuple indexing, tuple struct indexing, and struct field name positions are now correctly rejected](rust-lang/rust#145463) - [Closures marked with the keyword `static` are now syntactically invalid](rust-lang/rust#145604) - [Shebangs inside `--cfg` and `--check-cfg` arguments are no longer allowed](rust-lang/rust#146211) - [Add future incompatibility lint for temporary lifetime shortening in Rust 1.92](rust-lang/rust#147056) Cargo compatibility notes: - `cargo publish` no longer keeps `.crate` tarballs as final build artifacts when `build.build-dir` is set. These tarballs were previously included due to an oversight and are now treated as intermediate artifacts. To get `.crate` tarballs as final artifacts, use `cargo package`. In a future version, this change will apply regardless of `build.build-dir`. [#​15910](rust-lang/cargo#15910) - Adjust Cargo messages to match rustc diagnostic style. This changes some of the terminal colors used by Cargo messages. [#​15928](rust-lang/cargo#15928) - Tools and projects relying on the [internal details of Cargo's `build-dir`](https://doc.rust-lang.org/cargo/reference/build-cache.html) may not work for users changing their `build-dir` layout. For those doing so, we'd recommend proactively testing these cases particularly as we are considering changing the default location of the `build-dir` in the future ([cargo#16147](rust-lang/cargo#16147)). If you can't migrate off of Cargo's internal details, we'd like to learn more about your use case as we prepare to change the layout of the `build-dir` ([cargo#15010](rust-lang/cargo#15010)). <a id="1.91.0-Internal-Changes"></a> ## Internal Changes These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools. - [Update to LLVM 21](rust-lang/rust#143684) </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.
