Cleanup more of rustdoc
- Use `Item::from_def_id` for StructField
- Use `from_def_id_and_parts` for primitives and keywords
- Take `String` instead of `Symbol` in `from_def_id` - this avoids having to intern then immediately stringify the existing string.
- Remove unused `get_stability` and `get_deprecation`
- Remove unused `attrs` field from `primitives`
- Remove unused `attrs` field from `keywords`
This will probably conflict with https://github.com/rust-lang/rust/pull/79335 and I would prefer for that PR to land first - I'm anxious for https://github.com/rust-lang/rust/pull/77467 to land :)
Makes https://github.com/rust-lang/rust/issues/76998 easier to add.
r? `@GuillaumeGomez`
This preserves the current lint behavior for now.
Linting after item statements currently prevents the compiler from bootstrapping.
Fixing this is blocked on fixing this upstream in Cargo, and bumping the Cargo
submodule.
Loading a macro from libstd causes us to load serialized
`SyntaxContext`s in a platform-dependent way, causing the printed spans
to differ between platforms.
When parsing a statement (e.g. inside a function body),
we now consider `struct Foo {};` and `$stmt;` to each consist
of two statements: `struct Foo {}` and `;`, and `$stmt` and `;`.
As a result, an attribute macro invoke as
`fn foo() { #[attr] struct Bar{}; }` will see `struct Bar{}` as its
input. Additionally, the 'unused semicolon' lint now fires in more
places.
We now collect tokens for the underlying node wrapped by `StmtKind`
instead of storing tokens directly in `Stmt`.
`LazyTokenStream` now supports capturing a trailing semicolon after it
is initially constructed. This allows us to avoid refactoring statement
parsing to wrap the parsing of the semicolon in `parse_tokens`.
Attributes on item statements
(e.g. `fn foo() { #[bar] struct MyStruct; }`) are now treated as
item attributes, not statement attributes, which is consistent with how
we handle attributes on other kinds of statements. The feature-gating
code is adjusted so that proc-macro attributes are still allowed on item
statements on stable.
Two built-in macros (`#[global_allocator]` and `#[test]`) needed to be
adjusted to support being passed `Annotatable::Stmt`.
Cache pretty-print/retokenize result to avoid compile time blowup
Fixes#79242
If a `macro_rules!` recursively builds up a nested nonterminal
(passing it to a proc-macro at each step), we will end up repeatedly
pretty-printing/retokenizing the same nonterminals. Unfortunately, the
'probable equality' check we do has a non-trivial cost, which leads to a
blowup in compilation time.
As a workaround, we cache the result of the 'probable equality' check,
which eliminates the compilation time blowup for the linked issue. This
commit only touches a single file (other than adding tests), so it
should be easy to backport.
The proper solution is to remove the pretty-print/retokenize hack
entirely. However, this will almost certainly break a large number of
crates that were relying on hygiene bugs created by using the reparsed
`TokenStream`. As a result, we will definitely not want to backport
such a change.
Normalize `<X as Y>::T` for rustdoc
- Only run for `QPath::Resolved` with `Some` self parameter (`<X as Y>::T`)
- Fall back to the previous behavior if the path can't be resolved
The first commit is a pure refactor and should probably be reviewed by `@GuillaumeGomez.` I recommend reviewing the second commit on its own.
Fixes https://github.com/rust-lang/rust/issues/77459.

Upgrades the coverage map to Version 4
Changes the coverage map injected into binaries compiled with
`-Zinstrument-coverage` to LLVM Coverage Mapping Format, Version 4 (from
Version 3). Note, binaries compiled with this version will require LLVM
tools from at least LLVM Version 11.

Resolve inference variables before trying to remove overloaded indexing
Fixes#79152
This code was already set up to handle indexing an array. However, it
appears that we never end up with an inference variable for the slice
case, so the missing call to `resolve_vars_if_possible` had no effect
until now.

Validate use of parameters in naked functions
* Reject use of parameters inside naked function body.
* Reject use of patterns inside function parameters, to emphasize role
of parameters a signature declaration (mirroring existing behaviour
for function declarations) and avoid generating code introducing
specified bindings.
Closes issues below by considering input to be ill-formed.
Closes#75922.

Always invoke statement attributes on the statement itself
This is preparation for PR #78296, which will require us to handle
statement items in addition to normal items.
Rename `optin_builtin_traits` to `auto_traits`
They were originally called "opt-in, built-in traits" (OIBITs), but
people realized that the name was too confusing and a mouthful, and so
they were renamed to just "auto traits". The feature flag's name wasn't
updated, though, so that's what this PR does.
There are some other spots in the compiler that still refer to OIBITs,
but I don't think changing those now is worth it since they are internal
and not particularly relevant to this PR.
Also see <https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/opt-in.2C.20built-in.20traits.20(auto.20traits).20feature.20name>.
