2025-05-30Rollup merge of #141004 - matthewjasper:unicode-before-expansion, r=davidtwcoMatthias Krüger-0/+12
Report text_direction_codepoint_in_literal when parsing The lint is now reported in code that gets removed/modified/duplicated by macro expansion, and spans are more accurate so we don't get ICEs from trying to split a span in the middle of a character. This removes support for lint level attributes for `text_direction_codepoint_in_literal` except at the crate level, I don't think that there's an easy way around this when the lint can be reported on code that's removed by `cfg` or that is only in the input of a macro. Fixes #140281

2025-05-30Reorder fields in `hir::ItemKind` variants.Nicholas Nethercote-21/+21
Specifically `TyAlias`, `Enum`, `Struct`, `Union`. So the fields match the textual order in the source code. The interesting part of the change is in `compiler/rustc_hir/src/hir.rs`. The rest is extremely mechanical refactoring.
2025-05-29Rollup merge of #141705 - GuillaumeGomez:eslint-tidy, r=KobzolGuillaume Gomez-0/+102
Add eslint as part of `tidy` run Rustdoc uses `eslint` to run lints on the JS files. Currently you need to run it by hand since it's not part of any `x.py` command. This PR makes it part of `test tidy`. However, to prevent having all rust developers to install `npm` and `eslint`, I made it optional: if `eslint` is not installed, then the check is simply skipped (but will tell that it is being skipped). The second commit removes the manual checks from the docker file since `eslint` is run as part of tidy. cc `@lolbinarycat,` [#t-rustdoc > eslint seems to only be run in CI](https://rust-lang.zulipchat.com/#narrow/channel/266220-t-rustdoc/topic/eslint.20seems.20to.20only.20be.20run.20in.20CI/with/520761477)

2025-05-29Rollup merge of #138285 - beetrees:repr128-stable, r=traviscross,bjorn3Jacob Pratt-102/+94
Stabilize `repr128` ## Stabilisation report The `repr128` feature ([tracking issue](https://github.com/rust-lang/rust/issues/56071)) allows the use of `#[repr(u128)]` and `#[repr(i128)]` on enums in the same way that other primitive representations such as `#[repr(u64)]` can be used. For example: ```rust #[repr(u128)] enum Foo { One = 1, Two, Big = u128::MAX, } #[repr(i128)] enum Bar { HasThing(u16) = 42, HasSomethingElse(i64) = u64::MAX as i128 + 1, HasNothing, } ``` This is the final part of adding 128-bit integers to Rust ([RFC 1504](https://rust-lang.github.io/rfcs/1504-int128.html)); all other parts of 128-bit integer support were stabilised in #49101 back in 2018. From a design perspective, `#[repr(u128)]`/`#[repr(i128)]` function like `#[repr(u64)]`/`#[repr(i64)]` but for 128-bit integers instead of 64-bit integers. The only differences are: - FFI safety: as `u128`/`i128` are not currently considered FFI safe, neither are `#[repr(u128)]`/`#[repr(i128)]` enums (I discovered this wasn't the case while drafting this stabilisation report, so I have submitted #138282 to fix this). - Debug info: while none of the major debuggers currently support 128-bit integers, as of LLVM 20 `rustc` will emit valid debuginfo for both DWARF and PDB (PDB makes use of the same natvis that is also used for all enums with fields, whereas DWARF has native support). Tests for `#[repr(u128)]`/`#[repr(i128)]` enums include: - [ui/enum-discriminant/repr128.rs](https://github.com/rust-lang/rust/blob/385970f0c1fd0c09bac426b02f38300c0b1ba9a2/tests/ui/enum-discriminant/repr128.rs): checks that 128-bit enum discriminants have the correct values. - [debuginfo/msvc-pretty-enums.rs](https://github.com/rust-lang/rust/blob/385970f0c1fd0c09bac426b02f38300c0b1ba9a2/tests/debuginfo/msvc-pretty-enums.rs): checks the PDB debuginfo is correct. - [run-make/repr128-dwarf](https://github.com/rust-lang/rust/blob/385970f0c1fd0c09bac426b02f38300c0b1ba9a2/tests/run-make/repr128-dwarf/rmake.rs): checks the DWARF debuginfo is correct. Stabilising this feature does not require any changes to the Rust Reference as [the documentation on primitive representations](https://doc.rust-lang.org/nightly/reference/type-layout.html#r-layout.repr.primitive.intro) already includes `u128` and `i128`.

2025-05-28fix: Handle included files better in IDE layerLukas Wirth-31/+97
This does not fully fix things, but it introduces a function that can be used to fix occurences. When using `to_def` functionality, the input node needs to come from the macro expanded include, not the real file that was included. This does unfortunately add more caller burden, but there is not really a way around it.
