2021-12-18Rollup merge of #89090 - cjgillot:bare-dyn, r=jackh726Matthias Krüger-45/+3
Lint bare traits in AstConv. Removing the lint from lowering allows to: - make lowering querification easier; - have the lint implementation in only one place. r? `@estebank`
2021-12-15Rollup merge of #91888 - BoxyUwU:generic_arg_infer_aaaa, r=lcnrMatthias Krüger-2/+1
Handle unordered const/ty generics for object lifetime defaults *feel like I should have a PR description but cant think of what to put here* r? ```@lcnr```
2021-12-15Rollup merge of #91881 - Patrick-Poitras:stabilize-iter-zip, r=scottmcmMatthias Krüger-1/+0
Stabilize `iter::zip` Hello all! As the tracking issue (#83574) for `iter::zip` completed the final commenting period without any concerns being raised, I hereby submit this stabilization PR on the issue. As the pull request that introduced the feature (#82917) states, the `iter::zip` function is a shorter way to zip two iterators. As it's generally a quality-of-life/ergonomic improvement, it has been integrated into the codebase without any trouble, and has been used in many places across the rust compiler and standard library since March without any issues. For more details, I would refer to `@cuviper's` original PR, or the [function's documentation](https://doc.rust-lang.org/std/iter/fn.zip.html).

2021-12-13Keep info on pre-desugaring expression for better "incorrect `.await`" ↵Esteban Kuber-5/+6
suggestion Keep the `HirId` of `.await`ed expressions so in the case of a `fn` call on on a sync `fn`, we can suggest maybe turning it into an `async fn`.

2021-12-03Auto merge of #90737 - eholk:intofuture, r=tmandrybors-0/+2
Reintroduce `into_future` in `.await` desugaring This is a reintroduction of the remaining parts from https://github.com/rust-lang/rust/pull/65244 that have not been relanded yet. This isn't quite ready to merge yet. The last attempt was reverting due to performance regressions, so we need to make sure this does not introduce those issues again.

2021-11-19Rollup merge of #90990 - nnethercote:arenas-cleanup, r=oli-obkYuki Okushi-1/+1
Arenas cleanup I was looking closely at the arenas code and here are some small improvement to readability.
2021-11-18rustc: Remove `#[rustc_synthetic]`Vadim Petrochenkov-10/+2
This function parameter attribute was introduced in https://github.com/rust-lang/rust/pull/44866 as an intermediate step in implementing `impl Trait`, it's not necessary or used anywhere by itself.
2021-11-17Remove unnecessary lifetime argument from arena macros.Nicholas Nethercote-1/+1
Because it's always `'tcx`. In fact, some of them use a mixture of passed-in `$tcx` and hard-coded `'tcx`, so no other lifetime would even work. This makes the code easier to read.
2021-10-29Auto merge of #90380 - Mark-Simulacrum:revert-89558-query-stable-lint, r=lcnrbors-1/+0

Index and hash HIR as part of lowering Part of https://github.com/rust-lang/rust/pull/88186 ~Based on https://github.com/rust-lang/rust/pull/88880 (see merge commit).~ Once HIR is lowered, it is later indexed by the `index_hir` query and hashed for `crate_hash`. This PR moves those post-processing steps to lowering itself. As a side objective, the HIR crate data structure is refactored as an `IndexVec<LocalDefId, Option<OwnerInfo<'hir>>>` where `OwnerInfo` stores all the relevant information for an HIR owner. r? `@michaelwoerister` cc `@petrochenkov`
2021-10-17rustc_span: `Ident::invalid` -> `Ident::empty`Vadim Petrochenkov-1/+1
The equivalent for `Symbol`s was renamed some time ago (`kw::Invalid` -> `kw::Empty`), and it makes sense to do the same thing for `Ident`s.

Gather module items after lowering. This avoids having a non-local analysis inside lowering. By implementing `hir_module_items` using a visitor, we make sure that iterations and visitors are consistent.

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.

We only do this operation when incremental compilation is enabled. This avoids pessimizing the span handling for non-incremental compilation.

We force the relative span's parent to be absolute. This avoids having to handle long dependency chains.

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
