bootstrap: Unify test argument handling
Fixes#104198. Does *not* help with https://github.com/rust-lang/rust/issues/80124 because I couldn't figure out a reasonable way to omit `--lib` only for `panic_abort` and not other `std` dependencies.
- Remove unnecessary `test_kind` field and `TestKind` struct. These are just subsets of the existing `builder.kind` / `Kind` struct.
- Add a new `run_cargo_test` function which handles passing arguments to cargo based on `builder.config`
- Switch all Steps in `mod test` to `run_cargo_test` where possible
- Combine several steps into one `CrateBootstrap` step. These tests all do the same thing, just with different crate names.
- Fix `x test --no-doc`. This is much simpler after the refactors mentioned earlier, but I'm happy to split it into a separate PR if desired. Before, this would panic a lot because steps forgot to pass `--lib`.
- Use `cargo metadata` to determine whether a crate has a library
package or not
- Collect metadata for all workspaces, not just the root workspace and
cargo
- Don't pass `--lib` for crates without a library
- Use `run_cargo_test` for rust-installer
- Don't build documentation in `lint-docs` if `--no-doc` is passed

rustdoc: fix weird margins between Deref impl items
## Before
## After
## Description
In the old setup, if the dereffed-to item has multiple impl blocks, each one gets its own `div.impl-items` in the section, but there are no headers separating them. Since the last method in a `div.impl-items` has no bottom margin, and there are no margins between these divs, there is no margin between the last method of one impl and the first method of the following impl.
This patch fixes it by simplifying the HTML. Each Deref block gets exactly one `div.impl-items`, no matter how many impl blocks it actually has.
Add support for LibreSSL 3.7.x
This updates the `openssl-sys` crate to 0.9.87 to support building the toolchain against the system libraries provided by LibreSSL version 3.7.x.
LibreSSL 3.7.x has been supported since `openssl-sys` version 0.9.85.
Update tests for libtest `--format json`
This PR makes the test work on beta and stable, and adds a test ensuring the option is not available on beta and stable. Backported these commits from https://github.com/rust-lang/rust/pull/110414.
rustdoc: Add a new lint for broken inline code
This patch adds `rustdoc::unescaped_backticks`, a new rustdoc lint that will detect broken inline code nodes.
The lint woks by finding stray backticks and with some heuristics tries to guess where the second backtick might be missing.
Here is how it looks:
```rust
#![warn(rustdoc::unescaped_backticks)]
/// `add(a, b) is the same as `add(b, a)`.
pub fn add(a: i32, b: i32) -> i32 { a + b }
```
```text
warning: unescaped backtick
--> src/lib.rs:3:41
|
3 | /// `add(a, b) is the same as `add(b, a)`.
| ^
|
help: a previous inline code might be longer than expected
|
3 | /// `add(a, b)` is the same as `add(b, a)`.
| +
help: if you meant to use a literal backtick, escape it
|
3 | /// `add(a, b) is the same as `add(b, a)\`.
| +
```
If we can't get proper spans, for example if the doc comment comes from a macro expansion, we print the suggestion in help messages instead. Here's a [real-world example](https://docs.rs/tracing-subscriber/0.3.17/tracing_subscriber/layer/trait.Filter.html#method.max_level_hint):
```text
warning: unescaped backtick
--> /tracing-subscriber-0.3.17/src/layer/mod.rs:1400:9
|
1400 | / /// Returns an optional hint of the highest [verbosity level][level] that
1401 | | /// this `Filter` will enable.
1402 | | ///
1403 | | /// If this method returns a [`LevelFilter`], it will be used as a hint to
... |
1427 | | /// [`Interest`]: tracing_core::subscriber::Interest
1428 | | /// [rebuild]: tracing_core::callsite::rebuild_interest_cache
| |_____________________________________________________________________^
|
= help: a previous inline code might be longer than expected
change: Therefore, if the `Filter will change the value returned by this
to this: Therefore, if the `Filter` will change the value returned by this
= help: if you meant to use a literal backtick, escape it
change: [`rebuild_interest_cache`][rebuild] is called after the value of the max
to this: [`rebuild_interest_cache\`][rebuild] is called after the value of the max
```
You can find more examples [here](https://gist.github.com/lukas-code/7678ddf5c608aee97b3a669de80d3465).
A limitation of the current implementation is, that it cannot suggest removing misplaced backticks, for example [here](https://docs.rs/tikv-jemalloc-sys/0.5.3+5.3.0-patched/tikv_jemalloc_sys/fn.mallctl.html).
The lint is allowed by default ~~and nightly-only~~ for now, ~~but without a feature gate. This is similar to how `rustdoc::invalid_html_tags` and `rustdoc::bare_urls` were handled.~~
This version was released as part of a security fix for Wasmtime. The
fix didn't change Cranelift though, so this commit is not strictly
necessary, but also doesn't hurt.
Improve niche placement by trying two strategies and picking the better result
Fixes#104807Fixes#105371
Determining which sort order is better requires calculating the struct size (so we can calculate the niche offset). But that in turn depends on the field order, so happens after sorting. So the simple way to solve that is to run the whole thing twice and pick the better result.
1st commit is just code motion, the meat is in the later ones.

Don't duplicate anonymous lifetimes for async fn in traits
`record_lifetime_params_for_async` needs to be called outside of the scope of the function, or else it'll end up collecting anonymous lifetimes twice (those on the function and those within the `AnonymousCreateParameter` rib). This matches how `record_lifetime_params_for_async` is being used for functions with bodies below.
This fixes (partially) #110963 when the lifetimes are late-bound, but does not do so when the lifetimes are early-bound (as seen from the known-bug that I added).
Make sure that some stdlib method signatures aren't accidental refinements
In the process of implementing https://rust-lang.github.io/rfcs/3245-refined-impls.html, I found a bunch of stdlib implementations that accidentally "refined" their method signatures by dropping (unnecessary) bounds.
This isn't currently a problem, but may become one if/when method signature refining is stabilized in the future. Shouldn't hurt to make these signatures a bit more accurate anyways.
NOTE (just to be clear lol): This does not affect behavior at all, since we don't actually take advantage of refined implementations yet!
include source error for LoadLibraryExW
In #107595, we added retry behavior for LoadLibraryExW on Windows. If it fails we do not print the underlying error that Windows returned. This made #110889 a little harder to debug.
In this PR I am adding the source error in the message if it is available.
Clear response values for overflow in new solver
When we have an overflow, return a trivial query response. This fixes an ICE with the code described in #110544:
```rust
trait Trait {}
struct W<T>(T);
impl<T, U> Trait for W<(W<T>, W<U>)>
where
W<T>: Trait,
W<U>: Trait,
{}
fn impls<T: Trait>() {}
fn main() {
impls::<W<_>>()
}
```
Where, while proving `W<?0>: Trait`, we overflow but still apply the query response of `?0 = (W<?1>, W<?2>)`. Then while re-processing the query to validate that our evaluation result was stable, we get a different query response that looks like `?1 = (W<?3>, W<?4>), ?2 = (W<?5>, W<?6>)`, and so we trigger the ICE.
Also, by returning a trivial query response we also avoid the infinite-loop/OOM behavior of the old solver.
