Cleanup lower_generics_mut and make span be the bound itself Closes #86298 (supersedes those changes) r? `@cjgillot` since you reviewed the other PR (Used wrong branch for #89338)

2021-09-19Auto merge of #88703 - cjgillot:lazymod, r=petrochenkovbors-17/+2
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.

2021-09-15Rollup merge of #88775 - pnkfelix:revert-anon-union-parsing, r=davidtwcoManish Goregaokar-9/+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.

2021-09-10Give spans their parent item during lowering.Camille GILLOT-2/+7
We only do this operation when incremental compilation is enabled. This avoids pessimizing the span handling for non-incremental compilation.
2021-09-10Add sanity check.Camille GILLOT-2/+2
We force the relative span's parent to be absolute. This avoids having to handle long dependency chains.

2021-09-09Revert "Implement Anonymous{Struct, Union} in the AST"Felix S. Klock II-9/+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

The definition order is already close to the span order, and only differs in corner cases.
2021-09-01Auto merge of #87688 - camsteffen:let-else, r=cjgillotbors-95/+2
Introduce `let...else` Tracking issue: #87335 The trickiest part for me was enforcing the diverging else block with clear diagnostics. Perhaps the obvious solution is to expand to `let _: ! = ..`, but I decided against this because, when a "mismatched type" error is found in typeck, there is no way to trace where in the HIR the expected type originated, AFAICT. In order to pass down this information, I believe we should introduce `Expectation::LetElseNever(HirId)` or maybe add `HirId` to `Expectation::HasType`, but I left that as a future enhancement. For now, I simply assert that the block is `!` with a custom `ObligationCauseCode`, and I think this is clear enough, at least to start. The downside here is that the error points at the entire block rather than the specific expression with the wrong type. I left a todo to this effect. Overall, I believe this PR is feature-complete with regard to the RFC.

2021-08-27Introduce `~const`Deadbeef-1/+1
- [x] Removed `?const` and change uses of `?const` - [x] Added `~const` to the AST. It is gated behind const_trait_impl. - [x] Validate `~const` in ast_validation. - [ ] Add enum `BoundConstness` to the HIR. (With variants `NotConst` and `ConstIfConst` allowing future extensions) - [ ] Adjust trait selection and pre-existing code to use `BoundConstness`. - [ ] Optional steps (*for this PR, obviously*) - [ ] Fix #88155 - [ ] Do something with constness bounds in chalk
2021-08-24Auto merge of #87739 - Aaron1011:remove-used-attrs, r=wesleywiserbors-1/+1
Remove `Session.used_attrs` and move logic to `CheckAttrVisitor` Instead of updating global state to mark attributes as used, we now explicitly emit a warning when an attribute is used in an unsupported position. As a side effect, we are to emit more detailed warning messages (instead of just a generic "unused" message). `Session.check_name` is removed, since its only purpose was to mark the attribute as used. All of the callers are modified to use `Attribute.has_name` Additionally, `AttributeType::AssumedUsed` is removed - an 'assumed used' attribute is implemented by simply not performing any checks in `CheckAttrVisitor` for a particular attribute. We no longer emit unused attribute warnings for the `#[rustc_dummy]` attribute - it's an internal attribute used for tests, so it doesn't mark sense to treat it as 'unused'. With this commit, a large source of global untracked state is removed.
