This PR stabilizes the following target features: - div32 - lam-bh - lamcas - ld-seq-sa - scq

…_parsing` lints

…s from implementing `ConstParamTy`

Linux v7.1 will have our new MSRVs: Rust 1.85.0 and `bindgen` 0.71.1. Signed-off-by: Miguel Ojeda <ojeda@kernel.org>

Create a new `SharedContext::emit_dyn_lint_with_sess` method to simplify code when `Session` is not needed Remove crate name from `UnexpectedCfgCargoMacroHelp`

…d, r=JonathanBrouwer,petrochenkov Remove `AttributeLintKind` Part of rust-lang#153099. The `AttributeLintKind` type is finally gone! \o/ Diff is this big because I moved a file and a lot of `Diagnostic` types. :') r? @JonathanBrouwer

…features, r=Amanieu Partially stabilize LoongArch target features This PR stabilizes the following target features: - div32 - lam-bh - lamcas - ld-seq-sa - scq Docs PR: rust-lang/reference#2217 r? @Amanieu

…trochenkov Allow trailing `self` in more contexts Reference PR: - rust-lang/reference#2237 As a follow-up PR to rust-lang#152996, after this PR: 1. Trailing `self` can appear in paths 2. [E0429](https://doc.rust-lang.org/stable/error_codes/E0429.html#error-code-e0429) will be no longer emitted, `use ...::self [as target];` will be equivalent to `use ...::{self [as target]};` r? petrochenkov

…RalfJung,ShoyuVanilla Rip out rustc_layout_scalar_valid_range_* attribute support And either removes tests for it or replaces the uses with pattern types. primarily fixes rust-lang#135996 fixes rust-lang#147761 fixes rust-lang#133652

…rochenkov Change `ItemKind::Trait` to a field variant. This changes `ItemKind::Trait` from an octuple(!!) to an enum variant with fields. Their names were chosen to match up with existing usage and minimize renaming. I'm leaning towards renaming `ident` to `name` as well; let me know if that's desired.

…t-ice, r=TaKO8Ki Fix ICE: Scalar layout for non-primitive non-enum type unsafe binder `UnsafeBinder` uses the inner layout, but the debug layout check still looked at the outer type. Check the inner type first so this does not ICE. Tracking issue: rust-lang#130516 Closes: rust-lang#154426

…t-const-params, r=BoxyUwU Disallow non_exhaustive structs and enums with non_exhaustive variants from implementing `ConstParamTy` tracking issue rust-lang#154042 r? BoxyUwU
