BTreeSet: remove duplicated code by reusing `from_sorted_iter`
The method `BTreeSet::from_sorted_iter` was introduced in 49ccb7519f, but it was not consistently used throughout the codebase. As a result, some code redundantly reimplemented its logic. This commit fixes the problem.
Use tidy to sort `sym::*` items
Use tidy to sort the symbols in the invocation of `symbols!`, instead of implementing the ordering check inside the proc macro.
(asked `````@nnethercote````` about this on zulip, he didn't have any reservations about making this change)
This has a couple of benefits:
- tidy's "version sort" (thanks to rust-lang/rust#141311 !) is nicer than the naive-cmp sort, so, e.g. `AtomicI{8, 16, 32, 64, 128}` are properly sorted by bit width.
- consistency with the rest of the repo
- allows us to remove a bit of order-verifying code from the `symbols!` proc macro impl
update internal `send_signal` comment
the vxwork did not have the old comment updated in rust-lang/rust#141990 so update here;
signaling -> sending signals to because the latter reads better to me.
Add windows-gnullvm hosts to the manifest
I made a mistake testing https://github.com/rust-lang/rust/pull/140772 only with `rustup-toolchain-install-master` which doesn't care about the manifests.
This means windows-gnullvm self-hosting will have to wait one more release, unless this change is backported to beta and a new beta release is made, which doesn't seem worth the trouble.
rustdoc: show attributes on enum variants
mostly for #[non_exhaustive]
unsure if there's any attributes we should take care to *not* include, it could use `render_code_attribute` and `is_non_exhaustive` instead, if that is a concern.

Skip unnecessary components in x64 try builds
We unnecessarily rebuild `wasm-component-ld`, `llvm-bitcode-linker` and Cranelift during the intermediate PGO builds several times times, which is unnecessarily and increases the duration of try builds. This PR also disables some unnecessary dist components.

Do not include NUL-terminator in computed length
This PR contains just the first commit of rust-lang/rust#142579 which changes it so that the string length stored in the `Location` is the length of the `&str` rather than the length of the `&CStr`. Since most users will want the `&str` length, it seems better to optimize for that use-case.
There should be no visible changes in the behavior or API.
std::net: adding `unix_socket_exclbind` feature for solaris/illumos.
allows to have a tigher control over the binding exclusivness of the socket.

Only compute recursive callees once.
Inlining MIR in a cyclic call graph may create query cycles, which are ICEs. The current implementation `mir_callgraph_reachable(inlining_candidate, being_optimized)` checks if calling `inlining_candidate` may cycle back to `being_optimized` that we are currently inlining into.
This PR replaces this device with query `mir_callgraph_cyclic(being_optimized)` which searches the call graph for all cycles going back to `being_optimized`, and returns the set of functions involved in those cycles.
This is a tradeoff:
- in the current implementation, we perform more walks, but shallower;
- in this new implementation, we perform fewer walks, but exhaust the graph.
I'd have liked to compute this using some kind of SCC, but generic parameters make resolution path-dependent, so usual graph algorithms do not apply.
Insert checks for enum discriminants when debug assertions are enabled
Similar to the existing null-pointer and alignment checks, this checks for valid enum discriminants on creation of enums through unsafe transmutes. Essentially this sanitizes patterns like the following:
```rust
let val: MyEnum = unsafe { std::mem::transmute<u32, MyEnum>(42) };
```
An extension of this check will be done in a follow-up that explicitly sanitizes for extern enum values that come into Rust from e.g. C/C++.
This check is similar to Miri's capabilities of checking for valid construction of enum values.
This PR is inspired by saethlin@'s PR
https://github.com/rust-lang/rust/pull/104862. Thank you so much for keeping this code up and the detailed comments!
I also pair-programmed large parts of this together with vabr-g@.

gce: don't ICE on non-local const
Fixesrust-lang/rust#133808
I have absolutely no idea what I'm doing here, but I followed `@BoxyUwU` 's [instructions](https://github.com/rust-lang/rust/issues/133808#issuecomment-3009122957), and turns out this small change fixesrust-lang/rust#133808, and doesn't seem to break anything else.
(This code path is only reachable when the GCE feature gate is enabled, so even if it does break in a way that is not caught by current test coverage, I guess it's not as bad as breaking stable or non-incomplete features?)
Anyways, r? `@BoxyUwU` , if you don't mind.
hir_analysis: prohibit `dyn PointeeSized`
Fixesrust-lang/rust#142652
Supersedes rust-lang/rust#142663
`dyn PointeeSized` is nonsensical as a `dyn PointeeSized` needs to be `MetaSized`, so lets reject it to avoid hitting code paths that expect a builtin impl for `PointeeSized`

const checks for lifetime-extended temporaries: avoid 'top-level scope' terminology
This error recently got changed in https://github.com/rust-lang/rust/pull/140942 to use the terminology of "top-level scope", but after further discussion in https://github.com/rust-lang/reference/pull/1865 it seems the reference will not be using that terminology after all. So let's also remove it from the compiler again, and let's focus on what actually happens with these temporaries: their lifetime is extended until the end of the program.

Normalize before computing ConstArgHasType goal in new solver
This is a fix for rust-lang/rust#139905. See the description I left in the test.
I chose to fix this by normalizing the type before matching on its `.kind()` in `compute_const_arg_has_type_goal` (since it feels somewhat consistent with how we normalize types before assembling their candidates, for example); however, there are several other solutions that come to mind for fixing this ICE:
1. (this solution)
2. Giving `ConstKind::Error` a proper type, like `ConstKind::Value`, so that consts don't go from failing to passing `ConstArgHasType` goals after normalization (i.e. `UNEVALUATED` would normalize into a `ConstKind::Error(_, bool)` type rather than losing its type altogether).
3. Just suppressing the errors and accepting the fact that goals can go from fail->pass after normalization.
Thoughts? Happy to discuss this fix further.

suggest declaring modules when file found but module not defined
suggests declaring modules when a module is found but not defined, i.e
```
├── main.rs: `use thing::thang;`
└── thing.rs: `struct thang`
```
or
```
├── main.rs: `use thing::thang;`
└── thing
└── mod.rs: `struct thang`
```
which currently is just
```rust
error[E0432]: unresolved import `yeah`
--> src/main.rs:1:1
|
1 | use thing::thang;
| ^^^^^ use of unresolved module or unlinked crate `thing`
|
```
but now would have this nice help:
```text
= help: you may have forgotten to declare the module `thing`. use `mod thing` in this file to declare this module.
```
New const traits syntax
This PR only affects the AST and doesn't actually change anything semantically.
All occurrences of `~const` outside of libcore have been replaced by `[const]`. Within libcore we have to wait for rustfmt to be bumped in the bootstrap compiler. This will happen "automatically" (when rustfmt is run) during the bootstrap bump, as rustfmt converts `~const` into `[const]`. After this we can remove the `~const` support from the parser
Caveat discovered during impl: there is no legacy bare trait object recovery for `[const] Trait` as that snippet in type position goes down the slice /array parsing code and will error
