2022-01-01Move `PatKind::Lit` checking from ast_validation to ast loweringAaron Hill-47/+0
Fixes #92074 This allows us to insert an `ExprKind::Err` when an invalid expression is used in a literal pattern, preventing later stages of compilation from seeing an unexpected literal pattern.
2021-12-19Auto merge of #91957 - nnethercote:rm-SymbolStr, r=oli-obkbors-3/+2
Remove `SymbolStr` This was originally proposed in https://github.com/rust-lang/rust/pull/74554#discussion_r466203544. As well as removing the icky `SymbolStr` type, it allows the removal of a lot of `&` and `*` occurrences. Best reviewed one commit at a time. r? `@oli-obk`

2021-11-24Rollup merge of #90420 - GuillaumeGomez:rustdoc-internals-feature, r=camelidGuillaume Gomez-1/+5
Create rustdoc_internals feature gate As suggested by ``@camelid`` [here](https://github.com/rust-lang/rust/pull/90398#issuecomment-955093851), since `doc_keyword` and `doc_primitive` aren't meant to be stabilized, we could put them behind a same feature flag. This is pretty much what it would look like (needs to update the tests too). The tracking issue is https://github.com/rust-lang/rust/issues/90418. What do you think ``@rust-lang/rustdoc`` ?

2021-11-07ast: Fix naming conventions in AST structuresVadim Petrochenkov-33/+25
TraitKind -> Trait TyAliasKind -> TyAlias ImplKind -> Impl FnKind -> Fn All `*Kind`s in AST are supposed to be enums. Tuple structs are converted to braced structs for the types above, and fields are reordered in syntactic order. Also, mutable AST visitor now correctly visit spans in defaultness, unsafety, impl polarity and constness.

By adding #![doc(cfg_hide(foobar))] to the crate attributes the cfg #[cfg(foobar)] (and _only_ that _exact_ cfg) will not be implicitly treated as a doc(cfg) to render a message in the documentation.

If #![feature] is used outside the nightly channel for only lib features, the check will be delayed to the stability pass after parsing. This is done so that appropriate help messages can be shown if the #![feature] has been used needlessly
2021-09-15Rollup merge of #88775 - pnkfelix:revert-anon-union-parsing, r=davidtwcoManish Goregaokar-69/+0
Revert anon union parsing Revert PR #84571 and #85515, which implemented anonymous union parsing in a manner that broke the context-sensitivity for the `union` keyword and thus broke stable Rust code. Fix #88583.
2021-09-15Auto merge of #88558 - fee1-dead:const-drop, r=oli-obkbors-1/+3
Const drop The changes are pretty primitive at this point. But at least it works. ^-^ Problems with the current change that I can think of now: - [x] `~const Drop` shouldn't change anything in the non-const world. - [x] types that do not have drop glues shouldn't fail to satisfy `~const Drop` in const contexts. `struct S { a: u8, b: u16 }` This might not fail for `needs_non_const_drop`, but it will fail in `rustc_trait_selection`. - [x] The current change accepts types that have `const Drop` impls but have non-const `Drop` glue. Fixes #88424. Significant Changes: - `~const Drop` is no longer treated as a normal trait bound. In non-const contexts, this bound has no effect, but in const contexts, this restricts the input type and all of its transitive fields to either a) have a `const Drop` impl or b) can be trivially dropped (i.e. no drop glue) - `T: ~const Drop` will not be linted like `T: Drop`. - Instead of recursing and iterating through the type in `rustc_mir::transform::check_consts`, we use the trait system to special case `~const Drop`. See [`rustc_trait_selection::...::candidate_assembly#assemble_const_drop_candidates`](https://github.com/fee1-dead/rust/blob/const-drop/compiler/rustc_trait_selection/src/traits/select/candidate_assembly.rs#L817) and others. Changes not related to `const Drop`ping and/or changes that are insignificant: - `Node.constness_for_typeck` no longer returns `hir::Constness::Const` for type aliases in traits. This was previously used to hack how we determine default bound constness for items. But because we now use an explicit opt-in, it is no longer needed. - Removed `is_const_impl_raw` query. We have `impl_constness`, and the only existing use of that query uses `HirId`, which means we can just operate it with hir. - `ty::Destructor` now has a field `constness`, which represents the constness of the destructor. r? `@oli-obk`
2021-09-11Rollup merge of #88733 - Noble-Mushtak:88577, r=estebankJubilee-0/+14
Fix ICE for functions with more than 65535 arguments This pull request fixes #88577 by changing the `param_idx` field in the `Param` variant of `WellFormedLoc` from `u16` to `u32`, thus allowing for more than 65,535 arguments in a function. Note that I also added a regression test, but needed to add `// ignore-tidy-filelength` because the test is more than 8000 lines long.
2021-09-09Revert "Implement Anonymous{Struct, Union} in the AST"Felix S. Klock II-1/+0
This reverts commit 059b68dd677808e14e560802d235ad40beeba71e. Note that this was manually adjusted to retain some of the refactoring introduced by commit 059b68dd677808e14e560802d235ad40beeba71e, so that it could likewise retain the correction introduced in commit 5b4bc05fa57be19bb5962f4b7c0f165e194e3151
