either shift+click the Summary button,
or use the `_` key.
this collapses everything,
including (inherent) impl blocks.
no need for a special "expand all impl blocks"
method, as impl blocks are expanded during regular
"expand all".
doing "expand all" -> "collapse all" will always
result in only impl blocks being expaned.
some of the html is split up a bit awkwardly to
try to avoid introducing new whitespaces nodes,
which could affect display.

[rustdoc] Give more information into extracted doctest information
Follow-up of https://github.com/rust-lang/rust/pull/134531.
This update fragment the doctest code into its sub-parts to give more control to the end users on how they want to use it.
The new JSON looks like this:
```json
{
"format_version":2,
"doctests":[
{
"file":"$DIR/extract-doctests-result.rs",
"line":8,
"doctest_attributes":{
"original":"",
"should_panic":false,
"no_run":false,
"ignore":"None",
"rust":true,
"test_harness":false,
"compile_fail":false,
"standalone_crate":false,
"error_codes":[],
"edition":null,
"added_css_classes":[],
"unknown":[]
},
"original_code":"let x = 12;\nOk(())",
"doctest_code":{
"crate_level":"#![allow(unused)]\n",
"code":"let x = 12;\nOk(())",
"wrapper":{
"before":"fn main() { fn _inner() -> core::result::Result<(), impl core::fmt::Debug> {\n",
"after":"\n} _inner().unwrap() }",
"returns_result":true
}
},
"name":"$DIR/extract-doctests-result.rs - (line 8)"
}
]
}
```
for this doctest:
```rust
let x = 12;
Ok(())
```
With this, I think it matches what you need ``@ojeda?`` If so, once merged I'll update the patch I sent to RfL.

retpoline and retpoline-external-thunk flags (target modifiers) to enable retpoline-related target features
`-Zretpoline` and `-Zretpoline-external-thunk` flags are target modifiers (tracked to be equal in linked crates).
* Enables target features for `-Zretpoline-external-thunk`:
`+retpoline-external-thunk`, `+retpoline-indirect-branches`, `+retpoline-indirect-calls`.
* Enables target features for `-Zretpoline`:
`+retpoline-indirect-branches`, `+retpoline-indirect-calls`.
It corresponds to clang -mretpoline & -mretpoline-external-thunk flags.
Also this PR forbids to specify those target features manually (warning).

We can avoid it by using the `entry` API, which lets us do the
`assert_eq` comparison before `new_item` is consumed.
|
|
By making `JsonRenderer::item` take `&clean::Item` instead of a
`clean::Item`. This required also changing `FromClean` and `IntoJson`
methods to take references, which required a lot of follow-on sigil
wrangling that is mostly tedious.

Allow `#![doc(test(attr(..)))]` everywhere
This PR adds the ability to specify [`#![doc(test(attr(..)))]`](https://doc.rust-lang.org/nightly/rustdoc/write-documentation/the-doc-attribute.html#testattr) ~~at module level~~ everywhere in addition to allowing it at crate-root.
This is motivated by a recent PR #140323 (by ````@tgross35)```` where we have to duplicate 2 attributes to every single `f16` and `f128` doctests, by allowing `#![doc(test(attr(..)))]` at module level (and everywhere else) we can omit them entirely and just have (in both module):
```rust
#![doc(test(attr(feature(cfg_target_has_reliable_f16_f128))))]
#![doc(test(attr(expect(internal_features))))]
```
Those new attributes are appended to the one found at crate-root or at a previous module. Those "global" attributes are compatible with merged doctests (they already were before).
Given the small addition that this is, I'm proposing to insta-stabilize it, but I can feature-gate it if preferred.

Run wfcheck in one big loop instead of per module
Maybe we can merge this big loop in the future with the `par_hir_body_owners` call below and run typeck only on items that didn't fail wfcheck. For now let's just see if perf likes it, as it by itself should be beneficial to parallel rustc

`UsePath` contains a `SmallVec<[Res; 3]>`. This holds up to three `Res`
results, one per namespace (type, value, or macro). `lower_import_res`
takes a `PerNS<Option<Res<NodeId>>>` result and lowers it into the
`SmallVec`. This is pretty weird. The input `PerNS` makes it clear which
`Res` belongs to which namespace, but the `SmallVec` throws that
information away.
And code that operates on the `SmallVec` tends to use iteration (or even
just grabbing the first entry!) without knowing which namespace the
`Res` belongs to. Even weirder! Also, `SmallVec` is an overly flexible
type to use here, because it can contain any number of elements (even
though it's optimized for 3 in this case).
This commit changes `UsePath` so it also contains a
`PerNS<Option<Res<HirId>>>`. This type preserves more information and is
more self-documenting. The commit also changes a lot of the use sites to
access the result for a particular namespace. E.g. if you're looking up
a trait, it will be in the `Res` for the type namespace if it's present;
it's silly to look in the `Res` for the value namespace or macro
namespace. Overall I find the new code much easier to understand.
However, some use sites still iterate. These now use `present_items`
because that filters out the `None` results.
Also, `redundant_pub_crate.rs` gets a bigger change. A
`UseKind:ListStem` item gets no `Res` results, which means the old `all`
call in `is_not_macro_export` would succeed (because `all` succeeds on
an empty iterator) and the `ListStem` would be ignored. This is what we
want, but was more by luck than design. The new code detects `ListStem`
explicitly. The commit generalizes the name of that function
accordingly.
Finally, the commit also removes the `use_path` arena, because
`PerNS<Option<Res>>` impls `Copy` (unlike `SmallVec`) and it can be
allocated in the arena shared by all `Copy` types.

Rework `#[doc(cfg(..))]` checks as distinct pass in rustdoc
This PR reworks how rustdoc calls `rustc_attr_parsing::cfg_matches` to be in a separate pass, instead of being wired-up in a ad-hoc way, which is causing problems in https://github.com/rust-lang/rust/pull/138907#issuecomment-2920026627.
This un-does most part of https://github.com/rust-lang/rust/pull/140894, but the result is IMO much cleaner, easier to reason about, and most importantly no longer interfears with rust-lang/rust#138907.

Specifically `TyAlias`, `Enum`, `Struct`, `Union`. So the fields match
the textual order in the source code.
The interesting part of the change is in
`compiler/rustc_hir/src/hir.rs`. The rest is extremely mechanical
refactoring.

Make check-cfg diagnostics work in `#[doc(cfg(..))]`
This PR makes it so that the check-cfg `unexpected_cfgs` lint, is correctly emitted in `rustdoc`'s `#[doc(cfg(..))]`.
This is achieved by adding a custom trait to `cfg_matches` (the method that emits the lint) which permits `rustc` and `rustdoc` to each have their way to emitting lints (via buffered lints/AST for `rustc` and via `TyCtxt`/HIR for `rustdoc`).
The reason this is required is because buffered lints operates on the AST but `rustdoc` uses the HIR and by the time `rustdoc` calls `cfg_matches` we are way passed the point where buffered lints have been drain and emitted.

Moving the visibility stuff into the `from_fn` avoids the `Cow` and
makes the code a little shorter and simpler.
|
|
- `ret` only ever gets at most one entry, so it can be an `Option`
instead of a `Vec`.
- Which means we can use `filter_map` instead of `flat_map`.
- Move `trait_` next to the `ret` assignment, which can only happen
once.
- No need for `impls` to be a `Vec`, it can remain an iterator.
- Avoid `Result` when collecting `impls`.
