tree-wide: parallel: Fully removed all `Lrc`, replaced with `Arc` tree-wide: parallel: Fully removed all `Lrc`, replaced with `Arc` This is continuation of https://github.com/rust-lang/rust/pull/132282 . I'm pretty sure I did everything right. In particular, I searched all occurrences of `Lrc` in submodules and made sure that they don't need replacement. There are other possibilities, through. We can define `enum Lrc { Rc(Rc), Arc(Arc) }`. Or we can make `Lrc` a union and on every clone we can read from special thread-local variable. Or we can add a generic parameter to `Lrc` and, yes, this parameter will be everywhere across all codebase. So, if you think we should take some alternative approach, then don't merge this PR. But if it is decided to stick with `Arc`, then, please, merge. cc "Parallel Rustc Front-end" ( https://github.com/rust-lang/rust/issues/113349 ) r? SparrowLii `@rustbot` label WG-compiler-parallel

Rename rustc_contract to contract

2025-02-03T21:55:15+00:00

This has now been approved as a language feature and no longer needs a `rustc_` prefix. Also change the `contracts` feature to be marked as incomplete and `contracts_internals` as internal.

Separate contract feature gates for the internal machinery

2025-02-03T21:55:15+00:00

The extended syntax for function signature that includes contract clauses should never be user exposed versus the interface we want to ship externally eventually.

Express contracts as part of function header and lower it to the contract lang items

Rollup merge of #135882 - hkBst:master, r=estebank

simplify `similar_tokens` from `Option>` to `&[_]` All uses immediately invoke contains, so maybe a further simplification is possible.

Rollup merge of #133151 - tyrone-wu:trim-fn-ptr-whitespace, r=compiler-errors

Trim extra whitespace in fn ptr suggestion span Trim extra whitespace when suggesting removal of invalid qualifiers when parsing function pointer type. Fixes: #133083 --- I made a comment about the format of the diagnostic error message in https://github.com/rust-lang/rust/issues/133083#issuecomment-2480047875. I think the `.label` may be a little redundant if the diagnostic only highlights the bad qualifier instead of the entire `TyKind::BareFn` span. If it makes sense, I can include it in this PR.
