willglynn:rustdoc_output_target_feature_information, r=aDotInTheVoid
rustdoc-json: Output target feature information
`#[target_feature]` attributes refer to a target-specific list of features. Enabling certain features can imply enabling other features. Certain features are always enabled on certain targets, since they are required by the target's ABI. Features can also be enabled indirectly based on other compiler flags.
Feature information is ultimately known to `rustc`. Rather than force external tools to track it – which may be wildly impractical due to `-C target-cpu` – have `rustdoc` output `rustc`'s feature data.
This change is motivated by https://github.com/obi1kenobi/cargo-semver-checks/issues/1246, which intends to detect semver hazards caused by `#[target_feature]`.

rustdoc: Support inlined cross-crate re-exported trait aliases
Previously we'd just drop them. As a result of this PR, [`core::ptr::Thin`](https://doc.rust-lang.org/nightly/core/ptr/traitalias.Thin.html) will be admitted into the `std` façade!
Also, render the where clause *after* the bounds / the `=`, not before them, as it should be.

from "argument" to "parameter"
|
|
|
|
I'm removing empty identifiers everywhere, because in practice they
always mean "no identifier" rather than "empty identifier". (An empty
identifier is impossible.) It's better to use `Option` to mean "no
identifier" because you then can't forget about the "no identifier"
possibility.
Some specifics:
- When testing an attribute for a single name, the commit uses the
`has_name` method.
- When testing an attribute for multiple names, the commit uses the new
`has_any_name` method.
- When using `match` on an attribute, the match arms now have `Some` on
them.
In the tests, we now avoid printing empty identifiers by not printing
the identifier in the `error:` line at all, instead letting the carets
point out the problem.

Remove `kw::Empty` uses in rustdoc

`--doctest-build-arg`
More notably, the value of the new flag does *not* get lexed shell-like and ad hoc.
|
|
|
|
|
|
`sym::dummy` also appears to work.
|
|
Again by using `Option<Symbol>` to represent "no name".
|
|
Some `unwrap` uses here, but they are on paths involving item kinds that
are known to have an identifier.
|
|
To accurately reflect that RPITIT assoc items don't have a name. This
avoids the use of `kw::Empty` to mean "no name", which is error prone.
Helps with #137978.
|
|
Because all the other similar methods are on `AssocItem`.
|
|
From `hir::AssocItem`.
|
|
|
|
`hir::AssocItem` currently has a boolean `fn_has_self_parameter` field,
which is misplaced, because it's only relevant for associated fns, not
for associated consts or types. This commit moves it (and renames it) to
the `AssocKind::Fn` variant, where it belongs.
This requires introducing a new C-style enum, `AssocTag`, which is like
`AssocKind` but without the fields. This is because `AssocKind` values
are passed to various functions like `find_by_ident_and_kind` to
indicate what kind of associated item should be searched for, and having
to specify `has_self` isn't relevant there.
New methods:
- Predicates `AssocItem::is_fn` and `AssocItem::is_method`.
- `AssocItem::as_tag` which converts `AssocItem::kind` to `AssocTag`.
Removed `find_by_name_and_kinds`, which is unused.
`AssocItem::descr` can now distinguish between methods and associated
functions, which slightly improves some error messages.

Allow drivers to supply a list of extra symbols to intern
Allows adding new symbols as `const`s in external drivers, desirable in Clippy so we can use them in patterns to replace code like https://github.com/rust-lang/rust/blob/75530e9f72a1990ed2305e16fd51d02f47048f12/src/tools/clippy/clippy_lints/src/casts/cast_ptr_alignment.rs#L66
The Clippy change adds a couple symbols as a demo, the exact `clippy_utils` API and replacing other usages can be done on the Clippy side to minimise sync conflicts

Rename some `name` variables as `ident`.
It bugs me when variables of type `Ident` are called `name`. It leads to silly things like `name.name`. `Ident` variables should be called `ident`, and `name` should be used for variables of type `Symbol`.
This commit improves things by by doing `s/name/ident/` on a bunch of `Ident` variables. Not all of them, but a decent chunk.

rustdoc: Enable Markdown extensions when looking for doctests
Fixes #139064.
We should enable these to avoid misinterpreting uses of the extended

footnotes, as discovered in #139064.

Fix 2024 edition doctest panic output
Fixes #137970.
The problem was that the output was actually displayed by rustc itself because we're exiting with `Result<(), String>`, and the display is really not great. So instead, we get the output, we print it and then we return an `ExitCode`.
