Tracking issue rust-lang#67521, Layout::new in rust-lang#66254
Constify more of alloc::Layout Making more methods of `alloc::Layout` const would allow us to compute alignment/size information for arbitrary (sized) types at compile-time, including placing the information in associated constants. While `mem::size_of` and `mem::align_of` are already const and `Layout` is solely based on those, there is no guarantee in the implementation that a const derived from these functions will be exactly the same as what `Layout` uses and is subsequently used in a call to `alloc::alloc`. Constifying `Layout` makes this possible. First contribution to core, excuse my ignorance.
…r=oli-obk Correctly check for opaque types in `assoc_ty_def` Closes rust-lang#67856
Galloping search for binary_search_util This is unlikely to improve perf much unless for synthetic benchmarks, but I figure it likely won't hurt either.
…lacrum Move more of `rustc::lint` into `rustc_lint` Based on rust-lang#67806. Here we try to consolidate more of the linting infra into `rustc::lint`. Some high-level notes: - We now store an `Lrc<dyn Any + Send + Sync>` as opposed to `Lrc<LintStore>` in the `GlobalCtxt`. This enables us to avoid referring to the type, breaking a cyclic dependency, and so we can move things from `rustc::lint` to `rustc_lint`. - `in_derive_expansion` is, and needs to, be moved as a method on `Span`. - We reduce the number of ways on `tcx` to emit a lint so that the developer UX is more streamlined. - `LintLevelsBuilder` is moved to `rustc_lint::levels`, leaving behind `LintLevelMap/Set` in a purified form due to current constraints (hopefully fixable in the future after rust-lang#68133). - `struct_lint_level` is moved to `rustc::lint` due to current dependency constraints. - `rustc::lint::context` is moved to `rustc_lint::context`. - The visitors in `rustc::lint` are moved to `rustc_lint::passes`.
Unstabilize `Vec::remove_item` As concerned by @kornelski, @LukasKalbertodt, and @gnzlbg in rust-lang#40062. Reverts rust-lang#67727
…ns, r=Centril Add suggestions when encountering chained comparisons Ideally, we'd also prevent the type error, which is just extra noise, but that will require moving the error from the parser, and I think the suggestion makes things clear enough for now. Fixes rust-lang#65659.
