Add some diagnostic items for Clippy

It doesn't exist on Windows, so we bring our own unified diff implementation.
Fixes #82409

Remove storage markers if they won't be used during code generation
The storage markers constitute a substantial portion of all MIR
statements. At the same time, for builds without any optimizations,
the storage markers have no further use during and after MIR
optimization phase.
If storage markers are not necessary for code generation, remove them.

Rename the `tidy` binary to `rust-tidy`
This avoids naming collisions, particularly on Windows where the
dynamic library variable is PATH and setting it causes the in-tree
`tidy` to take precedence over the HTML tidy used by compiletest.
This doesn't change the x.py interface in any way, it still accepts `x.py test tidy` and prints error messages about `tidy`. It only changes the name of the file on disk.
Fixes https://github.com/rust-lang/rust/issues/82501.

Remove the x86_64-rumprun-netbsd target
Herein we remove the target from the compiler and the code from libstd intended to support the now-defunct rumprun project.
Closes #81514
|
|
The storage markers are removed at -C opt-level=0 and as a result output
of mir opt tests vary based on used optimization level. Use opt-level=1
for mir-opt tests to avoid the issue.

Update measureme dependency to the latest version
This version adds the ability to use `rdpmc` hardware-based performance
counters instead of wall-clock time for measuring duration. This also
introduces a dependency on the `perf-event-open-sys` crate on Linux
which is used when using hardware counters.

Replace const_cstr with cstr crate
This PR replaces the `const_cstr` macro inside `rustc_data_structures` with `cstr` macro from [cstr](https://crates.io/crates/cstr) crate.
The two macros basically serve the same purpose, which is to generate `&'static CStr` from a string literal. `cstr` is better because it validates the literal at compile time, while the existing `const_cstr` does it at runtime when `debug_assertions` is enabled. In addition, the value `cstr` generates can be used in constant context (which is seemingly not needed anywhere currently, though).

Only look for HTML `tidy` when running rustdoc tests
This avoids printing lots of unnecessary errors, as well as making the
test suite slightly faster. This doesn't fix the windows bug tracked by https://github.com/rust-lang/rust/issues/82501, though.

library: Normalize safety-for-unsafe-block comments
Almost all safety comments are of the form `// SAFETY:`,
so normalize the rest and fix a few of them that should
have been a `/// # Safety` section instead.
Furthermore, make `tidy` only allow the uppercase form. While
currently `tidy` only checks `core`, it is a good idea to prevent
`core` from drifting to non-uppercase comments, so that later
we can start checking `alloc` etc. too.

Jsondocck improvements
Adds 2 new commands, ```@is``` and ```@set`.``
```@is``` works like ```@has`,`` except instead of checking if any value matches, it checks that there is exactly one value, and it matches. This allows more precise testing.
```@set``` gets a value, and saves it to be used later. This makes it possible to check that an item appears in the correct module.
Once this lands, the rest of the test suite can be upgraded to use these.

Rustdoc gui tests
This is a reopening of #70533.
For this first version, there will be no screenshot comparison. Also, a big change compared to the previous version: the tests are now hosted in the rust repository directly. Since there is no image, it's pretty lightweight to say the least.
So now, only remains the nodejs script to run the tests and the tests themselves. Just one thing is missing: where should I put the documentation for these tests? I'm not sure where would be the best place for that. The doc will contain important information like the documentation of the framework used and how to install it (`npm install browser-ui-test`, but still needs to be put somewhere so no one is lost).
We'd also need to install the package when running the CI too. For now, it runs as long as we have nodejs installed, but I think we don't it to run in all nodejs targets?

Fix some Python2→3 error in publish_toolstate.py
Fix #82254.
The error is primarily due to `data = json.dumps(…)` producing a `str` instead of a `bytes`, which are different types on Python 3. But then `urllib.request.urlopen(…, data)` cannot accept `data` as a `str`, thus the error.
This PR added `.encode()` call after `json.dumps()` to ensure we are sending `bytes`. Additionally, we added type annotation to ensure things can statically type-check with `mypy` on both Python 2 and 3.

ast: Keep expansion status for out-of-line module items
I.e. whether a module `mod foo;` is already loaded from a file or not.
This is a pre-requisite to correctly treating inner attributes on such modules (https://github.com/rust-lang/rust/issues/81661).
With this change AST structures for `mod` items diverge even more for AST structure for the crate root, which previously used `ast::Mod`.
Therefore this PR removes `ast::Mod` from `ast::Crate` in the first commit, these two things are sufficiently different from each other, at least at syntactic level.
Customization points for visiting a "`mod` item or crate root" were also removed from AST visitors (`fn visit_mod`).
`ast::Mod` itself was refactored away in the second commit in favor of `ItemKind::Mod(Unsafe, ModKind)`.
