The comment explains it's for `unstable_offset_of`, but `offset_of` is now stable.

- Sort dependencies and features sections. - Add `tidy` markers to the sorted sections so they stay sorted. - Remove empty `[lib`] sections. - Remove "See more keys..." comments. Excluded files: - rustc_codegen_{cranelift,gcc}, because they're external. - rustc_lexer, because it has external use. - stable_mir, because it has external use.

When we encounter a `dyn Trait` that isn't object safe, look for its implementors. If there's one, mention using it directly If there are less than 9, mention the possibility of creating a new enum and using that instead. Account for object unsafe `impl Trait on dyn Trait {}`. Make a distinction between public and sealed traits. Fix rust-lang#80194.

By storing the unparsed values in `Config` and then parsing them within `run_compiler`, the parsing functions can use the main symbol interner, and not create their own short-lived interners. This change also eliminates the need for one `EarlyErrorHandler` in rustdoc, because parsing errors can be reported by another, slightly later `EarlyErrorHandler`.

They now only ever contains symbols.

It was added in 51938c6, a commit with a 7,720 line diff and a one line commit message. Even then the comment was incorrect; there was a removed a `build_output_filenames` call with a `&[]` argument in rustdoc, but the commit removed that call. In such a large commit, it's easy for small errors to occur.

Using `find` and `any` from `std` makes the code shorter and clearer.

Fix: Write access check of `prefix` and `sysconfdir` when DESTDIR is present. Improvement: Instead of repeatedly reading `DESTDIR` within each `fn prepare_dir` usage, read it once and pass it to the `fn prepare_dir`. Signed-off-by: onur-ozkan <work@onurozkan.dev>

- The early return can be right at the top. - The control flow is simplified with `if let`. - The `collect` isn't necessary. - The "Unconditionally" comment is erroneously duplicated from `check_attr_crate_type`, and can be removed.

For a local pattern with no space between `let` and `(` e.g.: let(_a) = 3; we were previously suggesting this illegal code: let_a =3; After this change the suggestion will instead be: let _a =3; (Note the space after `let`)

If a function incorrectly contains multiple `...` args, and is also not foreign or `unsafe extern "C"`, only emit the latter error once.

Trying to use C-variadics in a const function would previously fail with an error like "destructor of `VaListImpl<'_>` cannot be evaluated at compile-time". Add an explicit check for const C-variadics to provide a clearer error: "functions cannot be both `const` and C-variadic".

…en-args, r=GuillaumeGomez rustdoc: elide cross-crate default generic arguments Elide cross-crate generic arguments if they coincide with their default. TL;DR: Most notably, no more `Box<…, Global>` in `std`'s docs, just `Box<…>` from now on. Fixes rust-lang#80379. Also helps with rust-lang#44306. Follow-up to rust-lang#103885, rust-lang#107637. r? ``@ghost``

…=wesleywiser Clean up `compiler/rustc*/Cargo.toml` Mostly by sorting dependencies, plus some other minor things. r? ``@wesleywiser``

share some track_caller logic between interpret and codegen Also move the code that implements the track_caller intrinsics out of the core interpreter engine -- it's just a helper creating a const-allocation, doesn't need to be part of the interpreter core.

Add support for mipsel-unknown-netbsd, 32-bit LE mips.
