- [BETA] Fix `links` vars showing up for testing packages (rust-lang/cargo#9068)
[beta] Clippy backport field_reassign_with_default fix
cc `@ebroto` `@Manishearth`
We had multiple complaints about this lint landing in stable 1.49 with a FP hit quite often in real world code. We want to backport the fix for this, so it already gets into 1.50. A stable backport is not warranted by this IMO.

[beta] Backport of #6375 - field_reassign_with_default fix
With the pinned nightly we can test backports to our beta branch now 🎉
cc #6515
changelog: beta 1.50: Backport of private fields fix in [`field_reassign_with_default`] lints
[beta] backports
This backports accepted PRs and switches to bootstrapping from the released compiler:
* de-stabilize unsized raw ptr methods for Weak #80422
* Use package name for top-level directory in bare tarballs #80397
* Prevent caching normalization results with a cycle #80246
r? `@Mark-Simulacrum`
When normalizing a projection which results in a cycle, we would
cache the result of `project_type` without the nested obligations
(because they're not needed for inference). This would result in
the nested obligations only being handled once in fulfill, which
would avoid the cycle error.
Fixes#79714, a regresion from #79305 caused by the removal of
`get_paranoid_cache_value_obligation`.
validate promoteds
Turn on const-value validation for promoteds. This is made possible now that https://github.com/rust-lang/rust/issues/67534 is resolved.
I don't think this is a breaking change. We don't promote any unsafe operation any more (since https://github.com/rust-lang/rust/pull/77526 landed). We *do* promote `const fn` calls under some circumstances (in `const`/`static` initializers), but union field access and similar operations are not allowed in `const fn`. So now is a perfect time to add this check. :D

Highlight edition-specific keywords correctly in code blocks, accounting for code block edition modifiers
Previously, edition-specific keywords (such as `async` and `await`) were not highlighted in code blocks, regardless of what edition was set. With this PR, this issue is fixed.
Now, the following behavior happens:
- When a code block is explicitly set to edition X, keywords from edition X are highlighted
- When a code block is explicitly set to a version that does not contain those keywords from edition X (e.g. edition Y), keywords from edition X are **not** highlighted
- When a code block has no explicit edition, keywords from the edition passed via `--edition` to rustdoc are highlighted
For example, a project set with `edition = "2015"` in its `Cargo.toml` would not highlight `async`/`await` unless the code block was set to `edition2018`. Additionally, a project set with `edition = "2018"` in its `Cargo.toml` *would* highlight `async`/`await` unless the code block was set to a version that did not contain those keywords (e.g. `edition2015`).
This PR fixes#80004.

Exclude unnecessary info from CodegenResults
`foreign_module` and `wasm_import_module` are not needed for linking, and hence can be removed from CodegenResults.
Fixes#77857
Rename rustc_middle::lint::LintSource
Rename [`rustc_middle::lint::LintSource`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/lint/enum.LintSource.html) to `rustc_middle::lint::LintLevelSource`.
This enum represents the source of a *lint level*, not a lint. This should improve code readability.
Update: Also documents `rustc_middle::lint::LevelSource` to clarify.
Implemented a compiler diagnostic for move async mistake
Fixes#79694
First time contributing, so I hope I'm doing everything right.
(If not, please correct me!)
This code performs a check when a move capture clause is parsed. The check is to detect if the user has reversed the async move keywords and to provide a diagnostic with a suggestion to fix it.
Checked code:
```rust
fn main() {
move async { };
}
```
Previous output:
```txt
PS C:\Repos\move_async_test> cargo build
Compiling move_async_test v0.1.0 (C:\Repos\move_async_test)
error: expected one of `|` or `||`, found keyword `async`
--> src\main.rs:2:10
|
2 | move async { };
| ^^^^^ expected one of `|` or `||`
error: aborting due to previous error
error: could not compile `move_async_test`
```
New output:
```txt
PS C:\Repos\move_async_test> cargo +dev build
Compiling move_async_test v0.1.0 (C:\Repos\move_async_test)
error: the order of `move` and `async` is incorrect
--> src\main.rs:2:13
|
2 | let _ = move async { };
| ^^^^^^^^^^
|
help: try switching the order
|
2 | let _ = async move { };
| ^^^^^^^^^^
error: aborting due to previous error
error: could not compile `move_async_test`
```
Is there a file/module where these kind of things are tested?
Would love some feedback 😄
Stabilize `core::slice::fill`
Tracking issue https://github.com/rust-lang/rust/issues/70758
Stabilizes the `core::slice::fill` API in Rust 1.50, adding a `memset` doc alias so people coming from C/C++ looking for this operation can find it in the docs. This API hasn't seen any changes since we changed the signature in https://github.com/rust-lang/rust/pull/71165/, and it seems like the right time to propose stabilization. Thanks!

Remap instrument-coverage line numbers in doctests
This uses the `SourceMap::doctest_offset_line` method to re-map line
numbers from doctests. Remapping columns is not yet done, and rustdoc
still does not output the correct filename when running doctests in a
workspace.
Part of #79417 although I dont consider that fixed until both filenames
and columns are mapped correctly.
r? `@richkadel`
I might jump on zulip the comming days. Still need to figure out how to properly write tests for this, and deal with other doctest issues in the meantime.
BTreeMap: respect pointer provenance rules in split_off
The test cases for `split_off` reported a few more violations (now that they support -Zmiri-track-raw-pointers). The functions `shift_kv` and `shift_edges` do not fix anything, I think, but if `move_kv` and `move_edges` exist, they deserve to live too.
r? `@Mark-Simulacrum`
This is a squash of these commits:
- Highlight edition-specific keywords correctly in code blocks,
accounting for code block edition modifiers
- Fix unit tests
- Revert changes to rustc_span::symbol to prepare for merge of #80272
- Use new Symbol::is_reserved API from #80272
- Remove unused import added by accident when merging
