fix fold doc comment for multiline param list fn
|
|
`rustdoc` was filling a `target_modifiers` variable, but it was not
using the result.
In turn, that means that trying to use a dependency that set a target
modifier fails.
For instance, running:
```sh
RUSTC_BOOTSTRAP=1 rustc --edition=2024 --target=aarch64-unknown-none-softfloat --sysroot=/dev/null --emit=metadata -Zfixed-x18 --crate-type rlib --crate-name core $(rustc --print sysroot)/lib/rustlib/src/rust/library/core/src/lib.rs
echo '#![allow(internal_features)]
' | RUSTC_BOOTSTRAP=1 rustdoc --edition=2021 --target=aarch64-unknown-none-softfloat --sysroot=/dev/null -Zfixed-x18 --extern core=libcore.rmeta -
```
will fail with:
```text
error: mixing `-Zfixed-x18` will cause an ABI mismatch in crate `rust_out`
|
= help: the `-Zfixed-x18` flag modifies the ABI so Rust crates compiled with different values of this flag cannot be used together safely
= note: unset `-Zfixed-x18` in this crate is incompatible with `-Zfixed-x18=` in dependency `core`
= help: set `-Zfixed-x18=` in this crate or unset `-Zfixed-x18` in `core`
= help: if you are sure this will not cause problems, you may use `-Cunsafe-allow-abi-mismatch=fixed-x18` to silence this error
```
Thus save the targets modifiers in `Options` to then pass it to the
session options, so that eventually the diff can be performed as expected
in `report_incompatible_target_modifiers()`.

clif: Don't set the `compiler-builtins-no-f16-f128` feature
Since rust-lang/rust be35d37d8b6c ("Use the compiler to determine whether or not to enable f16 and f128"), `compiler-builtins` relies on `rustc` to report whether or not `f16` and `f128` are supported, which is reported by the backend. This means that there should no longer be any need to unconditionally disable the types for clif in Bootstrap.
Backend config: https://github.com/rust-lang/rust/blob/a955f1cd09a027363729ceed919952d09f76f28e/compiler/rustc_codegen_cranelift/src/lib.rs#L224-L233

Only run bootstrap tests in `x test` on CI
Discussed at https://rust-lang.zulipchat.com/#narrow/channel/122652-new-members/topic/Linux.20Distribution/with/530839642. The bootstrap tests can be sensitive of the environment where they are executed. And now that they are executed very early in the test pipeline, it can be annoying for people who just try to do `x test` when it fails on bootstrap tests.
We could move the bootstrap tests back to the end of the `x test` pipeline, but then it would just fail later. I'd prefer to only run them on CI by default.

Fix `./x check bootstrap` (again)
Redoes rust-lang/rust#134883 and reverts 40c2ca96411caaeab1563ff9041879f742d1d71b from rust-lang/rust#142416. Unfortunately I missed this during review.
- Commit 1: Reverts 40c2ca96411caaeab1563ff9041879f742d1d71b and re-applies rust-lang/rust#134883.
- Commit 2: Check `./x check bootstrap` in `pr-check-1` to catch "obvious" problems like this.

tests: debuginfo: Work around or disable broken tests on powerpc
f16 support for PowerPC has issues in LLVM, therefore we need a small workaround to prevent LLVM from emitting symbols that don't exist for PowerPC yet.
It also appears that rust-lang/rust#128973 applies to PowerPC targets as well, though I've only tested 64-bit Linux targets.

r=GuillaumeGomez
rustdoc: add ways of collapsing all impl blocks
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.
not sure the best way to add a GUI test.

Add `ignore-backends` annotations in failing GCC backend ui tests
Follow-up of https://github.com/rust-lang/rust/pull/144125.
In the GCC backend, we don't support all ui tests yet and we have a list of tests we currently ignore available [here](https://github.com/rust-lang/rustc_codegen_gcc/blob/master/tests/failing-ui-tests.txt).
This PR adds the `ignore-backends` annotations to the corresponding ui tests.
The second commit is a fix to compiletest, complaining about `ignore-backends`.

Let's revise both the new content in this PR as well as the remaining
text in the relevant chapters so as to better describe our current
processes related to language features and their stabilizations.
For the new stabilization report template, based on reviewing its
early use and well as reviewing earlier stabilization reports, we've
revised it editorially and added questions designed to capture
additional details to which we commonly want people to speak.
|
|
- Address Call for Testing review feedback
- Address Affiliated work review feedback
- Drop "stabilization is easy" part
- Fix broken feature gate examples
- Elaborate on stabilization report summarization aspects
- Recommend waiting a bit for team nominations
- Make Stabilization Template markdown copy friendly
- Register stabilization report template
- Drop unfinished sentence
- Clarify stabilization report template is for language features
- Add test coverage elaboration
- Add UB checks / opt question
- Amend test coverage explanation
- Mention OSS nightly users

This check is relatively cheap, and is a quick way to root out breaking
check flow of `bootstrap` itself.
|
|
I missed this during review. We cannot declare a `tests` module within
`shared_helpers.rs` itself, as shim binaries that tries to include the
`shared_helpers` module through `#[path = ".."]` attributes would fail
to find it, breaking `./x check bootstrap`.
This reverts commit `40c2ca96411caaeab1563ff9041879f742d1d71b`.

Remove dead code and extend test coverage and diagnostics around it
I was staring a bit at the `dont_niche_optimize_enum` variable and figured out that part of it is dead code (at least today it is). I changed the diagnostic and test around the code that makes that part dead code, so everything that makes removing that code sound is visible in this PR
