This is only to make the generated DOT more legible.
Replace O(n^3) text matching with inexpensive hash set lookups. On my machine this reduces the total runtime of complete run-make-fulldeps suite from roughly 75 seconds to 45 seconds.
These are the repositories I've moved from rust-lang-nursery to rust-lang, so we should update the submodules too.
It remains as a comment in `error_codes.rs` for consistency with other unused errors.
If __LITTLE_ENDIAN__ is missing, libunwind assumes big endian and reads unwinding instructions wrong on ARM EHABI. Fix rust-lang#65765
Module level docs should resolve intra-doc links as locally as possible. As such, this commit alters the heuristic for finding intra-doc links such that we attempt to resolve names mentioned in *inner* documentation comments within the (sub-)module rather that from the context of its parent.

Add lint and tests for unnecessary parens around types This is my first contribution to the Rust project, so I apologize if I'm not doing things the right way. The PR fixes rust-lang#64169. It adds a lint and tests for unnecessary parentheses around types. I've run `tidy` and `rustfmt` — I'm not totally sure it worked right, though — and I've tried to follow the instructions linked in the readme. I tried to think through all the variants of `ast::TyKind` to find exceptions to this lint, and I could only find the one mentioned in the original issue, which concerns types with `dyn`. I'm not a Rust expert, thought, so I may well be missing something. There's also a problem with getting this to build. The new lint catches several things in the, e.g., `core`. Because `x.py` seems to build with an equivalent of `-Werror`, what would have been warnings cause the build to break. I got it to build and the tests to pass with `--warnings warn` on my `x.py build` and `x.py test` commands.
…=estebank Fix `-Zunpretty=mir-cfg` to render multiple items `-Zunpretty=mir-cfg` outputs DOT to stdout for all items being compiled. However, it puts all of these items in separate `digraph`s, which means the result of redirecting that output to a file is not valid. Most dot renderers (I have tried `dot` and `xdot`) cannot render the output. This PR checks to see if `write_mir_graphviz` will process multiple items, and writes them each as a `subgraph` in a single, top-level `digraph`. As a result, DOT can be viewed without manually editing the output file. The output is unchanged when printing a single item (e.g.`-Zunpretty=mir-cfg=item_name`). Here's the output of `xdot` for a rust file containing three items:  The borders are a result of the nonstandard–but well-supported–[`cluster` prefix](https://graphviz.gitlab.io/_pages/doc/info/lang.html) (search for "Subgraphs and Clusters"). They will not appear if your renderer does not support this extension, but the graph will still render properly.

…nisheart,GuillaumeGomez rustdoc: Resolve module-level doc references more locally Module level docs should resolve intra-doc links as locally as possible. As such, this commit alters the heuristic for finding intra-doc links such that we attempt to resolve names mentioned in *inner* documentation comments within the (sub-)module rather that from the context of its parent. I'm hoping that this fixes rust-lang#55364 though right now I'm not sure it's the right fix. r? @GuillaumeGomez

… r=eddyb Make `promote_consts` emit the errors when required promotion fails A very minimal version of rust-lang#65942. This will cause a generic "argument X is required to be a constant" message for `simd_shuffle` LLVM intrinsics instead of the [custom one](https://github.com/rust-lang/rust/blob/caa1f8d7b3b021c86a70ff62d23a07d97acff4c4/src/librustc_mir/transform/qualify_consts.rs#L1616). It may be possible to remove this special-casing altogether after rust-lang/stdarch#825. r? @eddyb

…ichton Fix libunwind build: Define __LITTLE_ENDIAN__ for LE targets If `__LITTLE_ENDIAN__` is missing, libunwind assumes big endian and reads unwinding instructions wrong on ARM EHABI. Fix rust-lang#65765 Technical background in referenced bug. I didn't run any automated tests, just built a simple panicking program using the fixed toolchain and panicking started to work. Tried with `catch_unwind()` and that seems to work now too. libunwind's log seems ok now, I can paste it if needed.

Fix incorrect diagnostics for expected type in E0271 with an associated type
With code like the following code:
```rust
#[derive(Debug)]
struct Data {}
fn do_stuff<'a>(iterator: impl Iterator<Item = &'a Data>) {
for item in iterator {
println!("{:?}", item)
}
}
fn main() {
let v = vec![Data {}];
do_stuff(v.into_iter());
}
```
the diagnostic (in nightly & stable) wrongly complains about the expected type:
```
error[E0271]: type mismatch resolving `<std::vec::IntoIter<Data> as std::iter::Iterator>::Item == &Data`
--> src/main.rs:15:5
|
5 | fn do_stuff<'a>(iterator: impl Iterator<Item = &'a Data>) {
| -------- --------------- required by this bound in `do_stuff`
...
15 | do_stuff(v.into_iter());
| ^^^^^^^^ expected struct `Data`, found &Data
|
= note: expected type `Data`
found type `&Data`
```
This PR fixes this issue by flipping the expected/actual values where appropriate, so it looks like this:
```
error[E0271]: type mismatch resolving `<std::vec::IntoIter<Data> as std::iter::Iterator>::Item == &Data`
--> main.rs:15:5
|
5 | fn do_stuff<'a>(iterator: impl Iterator<Item = &'a Data>) {
| -------- --------------- required by this bound in `do_stuff`
...
15 | do_stuff(v.into_iter());
| ^^^^^^^^ expected &Data, found struct `Data`
|
= note: expected type `&Data`
found type `Data`
```
This improves the output of a lot of existing tests (check out `associated-types-binding-to-type-defined-in-supertrait`!).
The only change which I wasn't too sure about is in the test `associated-types-overridden-binding-2`, but I think it's an improvement and the underlying problem is with handling of `trait_alias`.
Fix rust-lang#57226, fix rust-lang#64760, fix rust-lang#58092.
