Stabilize self_struct_ctor feature.
[**Tracking Issue**](https://github.com/rust-lang/rust/issues/51994)
|
|
Clean up and streamline the pretty-printer
Some minor improvements.
|
|
Reuse the `P` in `InvocationCollector::fold_{,opt_}expr`.
This requires adding a new method, `P::filter_map`.
This commit reduces instruction counts for various benchmarks by up to
0.7%.

Update outdated code comments in StringReader
For the detection of newlines in the lexer, this is now done in `analyze_source_file.rs`.

Suggest appropriate place for lifetime when declared after type arguments

`pretty_print` takes a `Token` and `match`es on it. But the particular
`Token` kind is known at each call site, so this commit splits it into
five functions: `pretty_print_eof`, `pretty_print_begin`, etc.
This commit also does likewise with `print`, though there is one
callsite for `print` where the `Token` kind isn't known, so a generic
`print` has to stay (but it now just calls out to the various `print_*`
functions).
|
|
`Printer::word` takes a `&str` and converts it into a `String`, which
causes an allocation. But that allocation is rarely necessary, because
`&str` is almost always a `&'static str` or a `String` that won't be
used again.
This commit changes `Token::String` so it holds a `Cow<'static, str>`
instead of a `String`, which avoids a lot of allocations.

They are unused. The commit also adds some blank lines between some
methods.

This commit converts some 2-space indents to 4-space indents.

Fix stability hole with `static _`
The `underscore_const_names` only gated const items with `_` as the name.
`static _: () = ();` works on beta without feature gates right now, this PR fixes that.

Ignore non-semantic tokens for 'probably_eq' streams.
Improves the situation in #43081 by skipping typically non-semantic tokens when checking for 'probably_eq'.

Clean up some non-mod-rs stuff.
This includes the following:
- Remove unused `non_modrs_mods` from `ParseSess` which as only used for feature gate diagnostics.
- Remove the vestiges of the feature gate tests in `test/ui`, they were only partially removed during stabilization.
- Fix the run-pass test, it was accidentally removed during stabilization.
- Add a ui test to verify error behavior for missing inline-nested mods.
- Add some tests for `#[path]` for inline-nested mods (both mod and non-mod-rs).
- Enable the diagnostic tests on windows, they should be fixed by #49478.
