Restore `use` suggestion for `dyn` method call requiring `Sized`
Add the suggestion back that I accidentally removed in 88f2140d8736329610a4c0bd8000e164c9170537 because I didn't understand that suggestion was actually useful...
Fixes #105159

Keep track of the start of the argument block of a closure
This removes a call to `tcx.sess.source_map()` from [compiler/rustc_trait_selection/src/traits/error_reporting/mod.rs](https://github.com/rust-lang/rust/compare/master...SarthakSingh31:issue-97417-1?expand=1#diff-8406bbc0d0b43d84c91b1933305df896ecdba0d1f9269e6744f13d87a2ab268a) as required by #97417.
VsCode automatically applied `rustfmt` to the files I edited under `src/tools`. I can undo that if its a problem.

Fix ICE on parsing an invalid variable declaration as a statement like:
```
macro_rules! m { ($s:stmt) => {} }
m! { var x }
```

Merge generics and where predicates and prevent duplicates in where predicates
Part of #104886 (I didn't include bounds from parent trait yet as I think the PR is already big enough).
Also we'll need to run a perf check.
cc `@fmease` since you worked a bit on this.

Don't elide type information when printing E0308 with `-Zverbose`
When we pass `-Zverbose`, we kinda expect for all `_` to be replaced with more descriptive information, for example --
```
= note: expected fn pointer `fn(_, u32)`
found fn item `fn(_, i32) {foo}`
```
Where `_` is the "identical" part of the fn signatures, now gets rendered as:
```
= note: expected fn pointer `fn(i32, u32)`
found fn item `fn(i32, i32) {foo}`
```

Rustdoc-Json: Don't inline foreign traits
It wasn't done correctly, and [we want to move towards only having local items in the index, and making foreign items easier to resolved](https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/Rustdoc.20JSON.3A.20Include.20All.20Foreign.20Items.3F)
Fixes #105025. This means #105015 is included to test this
Fixes #105022

Check lifetime param count in `collect_trait_impl_trait_tys`
We checked the type and const generics count, but not the lifetimes, which were handled in a different function.

sparc-struct-abi: work around new tail-call optimization
Upstream LLVM change https://reviews.llvm.org/D138741 introduced some new tail-call smarts for SPARC which broke some of the checks in this test. Rather than adjust the test expectations, we add an extra no-args function that can get tail-called or not without hurting the needs of the test.

v8a as default aarch64 target
After https://github.com/llvm/llvm-project/commit/8689f5e landed, LLVM takes the intersection of v8a and v8r as default. This commit brings back v8a support by explicitly specifying v8a in the feature list.
This should solve #97724.
p.s. a bit more context can also be found in https://github.com/llvm/llvm-project/issues/57904#issuecomment-1329555590.

Add `type_ascribe!` macro as placeholder syntax for type ascription
This makes it still possible to test the internal semantics of type ascription even once the `:`-syntax is removed from the parser. The macro now gets used in a bunch of UI tests that test the semantics and not syntax of type ascription.
I might have forgotten a few tests but this should hopefully be most of them. The remaining ones will certainly be found once type ascription is removed from the parser altogether.
Part of #101728

Because the error message that emit out is from main error of parser
The information of enum variant disappears while parsing enum variant with error
We only check the syntax of expecting token, i.e, in case #103869
It will error it without telling the message that this error is from pasring enum variant.
Propagate the sub-error from parsing enum variant to the main error of parser by chaining it with map_err
Check the sub-error before emitting the main error of parser and attach it.
Fix #103869

rustc_ast_lowering: Stop lowering imports into multiple items
Lower them into a single item with multiple resolutions instead.
This also allows to remove additional `NodId`s and `DefId`s related to those additional items.
|
|
This avoids calling `early_lint_node` twice.
Note: one `early_lint_node` call had `!pre_expansion` for the second
argument and the other had `false`. The new single call just has
`!pre_expansion`. This results in a reduction of duplicate error
messages in some `ui-fulldeps` tests. The order of some `ui-fulldeps`
output also changes, but that doesn't matter.

Because it complicates lint implementation greatly.
