aa05f99001 Auto merge of #102701 - flba-eb:add_qnx_nostd_support, r=cjgillot
Add tier 3 no_std AArch64/x86_64 support for the QNX Neutrino RTOS

This change allows to compile `no_std` applications for the QNX Neutrino Real-time operating system for ARM 64 bit CPUs.
Tested with QNX Neutrino 7.1.

Partially discussed in [zulip](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Adding.20QNX.20as.20target).

---

> ## Tier 3 target policy
>
> At this tier, the Rust project provides no official support for a target, so we
place minimal requirements on the introduction of targets.
>
>A proposed new tier 3 target must be reviewed and approved by a member of the
compiler team based on these requirements. The reviewer may choose to gauge
broader compiler team consensus via a [Major Change Proposal (MCP)][MCP].
>
>A proposed target or target-specific patch that substantially changes code
shared with other targets (not just target-specific code) must be reviewed and
approved by the appropriate team for that shared code before acceptance.
>
>- A tier 3 target must have a designated developer or developers (the "target
  maintainers") on record to be CCed when issues arise regarding the target.
  (The mechanism to track and CC such developers may evolve over time.)

See also nto-qnx.md; designated developers are:

- Florian Bartels, `Florian.Bartels@elektrobit.com`, https://github.com/flba-eb
- Tristan Roach, `TRoach@blackberry.com`, https://github.com/gh-tr

> - Targets must use naming consistent with any existing targets; for instance, a
  target for the same CPU or OS as an existing Rust target should use the same
  name for that CPU or OS. Targets should normally use the same names and
  naming conventions as used elsewhere in the broader ecosystem beyond Rust
  (such as in other toolchains), unless they have a very good reason to
  diverge. Changing the name of a target can be highly disruptive, especially
  once the target reaches a higher tier, so getting the name right is important
  even for a tier 3 target.
>  - Target names should not introduce undue confusion or ambiguity unless
    absolutely necessary to maintain ecosystem compatibility. For example, if
    the name of the target makes people extremely likely to form incorrect
    beliefs about what it targets, the name should be changed or augmented to
    disambiguate it.

`aarch64-unknown-nto-qnx7.1.0` and `x86_64-pc-nto-qnx7.1.0` have been chosen as these
strings are used in the official QNX Neutrino toolchain (for `C`/`C++`). It should also
harmonize with the other Rust targets.

The version (`7.1.0 `) is needed because libc needs to distinguish between different
versions (`target_env` is set to `710` for QNX Neutrino 7.1): For example, functions are removed from 7.0
to 7.1, sometimes the signature of functions is slightly changed or size/alignment of structs.
I'm expecting the same for future versions.
This works very well in e.g. `libc` (tested with 7.0 which I'm not going to support).

> - Tier 3 targets may have unusual requirements to build or use, but must not
  create legal issues or impose onerous legal terms for the Rust project or for
  Rust developers or users.
>  - The target must not introduce license incompatibilities.

No issue as far as I can see.

>  - Anything added to the Rust repository must be under the standard Rust
    license (`MIT OR Apache-2.0`).

Ok

>  - The target must not cause the Rust tools or libraries built for any other
    host (even when supporting cross-compilation to the target) to depend
    on any new dependency less permissive than the Rust licensing policy. This
    applies whether the dependency is a Rust crate that would require adding
    new license exceptions (as specified by the `tidy` tool in the
    rust-lang/rust repository), or whether the dependency is a native library
    or binary. In other words, the introduction of the target must not cause a
    user installing or running a version of Rust or the Rust tools to be
    subject to any new license requirements.

No change for host tools. When cross-compiling for QNX Neutrino, the compiler/linker
driver "qcc" is called. It should be possible (but not tested) to use other
(OSS) compilers/linkers to produce working binaries.

>  - Compiling, linking, and emitting functional binaries, libraries, or other
    code for the target (whether hosted on the target itself or cross-compiling
    from another target) must not depend on proprietary (non-FOSS) libraries.
    Host tools built for the target itself may depend on the ordinary runtime
    libraries supplied by the platform and commonly used by other applications
    built for the target, but those libraries must not be required for code
    generation for the target; cross-compilation to the target must not require
    such libraries at all. For instance, `rustc` built for the target may
    depend on a common proprietary C runtime library or console output library,
    but must not depend on a proprietary code generation library or code
    optimization library. Rust's license permits such combinations, but the
    Rust project has no interest in maintaining such combinations within the
    scope of Rust itself, even at tier 3.

Only rustc is required for code generation (i.e. no additional libraries to
generate code). Linking of executables requires the ordinary runtime libraries
`crt` and `libc`.

>  - "onerous" here is an intentionally subjective term. At a minimum, "onerous"
    legal/licensing terms include but are *not* limited to: non-disclosure
    requirements, non-compete requirements, contributor license agreements
    (CLAs) or equivalent, "non-commercial"/"research-only"/etc terms,
    requirements conditional on the employer or employment of any particular
    Rust developers, revocable terms, any requirements that create liability
    for the Rust project or its developers or users, or any requirements that
    adversely affect the livelihood or prospects of the Rust project or its
    developers or users.
>- Neither this policy nor any decisions made regarding targets shall create any
  binding agreement or estoppel by any party. If any member of an approving
  Rust team serves as one of the maintainers of a target, or has any legal or
  employment requirement (explicit or implicit) that might affect their
  decisions regarding a target, they must recuse themselves from any approval
  decisions regarding the target's tier status, though they may otherwise
  participate in discussions.
>  - This requirement does not prevent part or all of this policy from being
    cited in an explicit contract or work agreement (e.g. to implement or
    maintain support for a target). This requirement exists to ensure that a
    developer or team responsible for reviewing and approving a target does not
    face any legal threats or obligations that would prevent them from freely
    exercising their judgment in such approval, even if such judgment involves
    subjective matters or goes beyond the letter of these requirements.

I see no issues with any of the above.

>- Tier 3 targets should attempt to implement as much of the standard libraries
  as possible and appropriate (`core` for most targets, `alloc` for targets
  that can support dynamic memory allocation, `std` for targets with an
  operating system or equivalent layer of system-provided functionality), but
  may leave some code unimplemented (either unavailable or stubbed out as
  appropriate), whether because the target makes it impossible to implement or
  challenging to implement. The authors of pull requests are not obligated to
  avoid calling any portions of the standard library on the basis of a tier 3
  target not implementing those portions.

`core` and `alloc` should be working (no change required). `std` implementation
is ongoing and will be provided separately.

>- The target must provide documentation for the Rust community explaining how
  to build for the target, using cross-compilation if possible. If the target
  supports running binaries, or running tests (even if they do not pass), the
  documentation must explain how to run such binaries or tests for the target,
  using emulation if possible or dedicated hardware if necessary.

see nto-qnx.md

>- Tier 3 targets must not impose burden on the authors of pull requests, or
  other developers in the community, to maintain the target. In particular,
  do not post comments (automated or manual) on a PR that derail or suggest a
  block on the PR based on a tier 3 target. Do not send automated messages or
  notifications (via any medium, including via ``@`)` to a PR author or others
  involved with a PR regarding a tier 3 target, unless they have opted into
  such messages.
>  - Backlinks such as those generated by the issue/PR tracker when linking to
    an issue or PR are not considered a violation of this policy, within
    reason. However, such messages (even on a separate repository) must not
    generate notifications to anyone involved with a PR who has not requested
    such notifications.

Ok

>- Patches adding or updating tier 3 targets must not break any existing tier 2
  or tier 1 target, and must not knowingly break another tier 3 target without
  approval of either the compiler team or the maintainers of the other tier 3
  target.
>  - In particular, this may come up when working on closely related targets,
    such as variations of the same architecture with different features. Avoid
    introducing unconditional uses of features that another variation of the
    target may not have; use conditional compilation or runtime detection, as
    appropriate, to let each target run code supported by that target.

It's my understanding that while not *all* `src/test/ui` tests are compiler-related, the bulk of them are, so I think it makes sense for this to go to the compiler triagebot category (T-compiler and T-compiler-contributors) instead of fallback, which consists of just `@Mark-Simulacrum.` Though if anyone diagrees, feel free to close this PR.

## Description

The switch ("slider") is designed to give the application a "physical" feel, but nothing else in here really followed through. They didn't support the "flick" gesture that real iOS switches support, and the radio buttons that were also used in Rustdoc Settings were a more "classic" form element anyway.

Also, while switches are the exclusive toggle design on iOS (since [Apple HIG] reserves checkboxes for Mac only), the [Google Material] guidelines say that lists of switches are bad, and you should just use check boxes.

Rollup merge of #104214 - Nilstrieb:returns_impl_Ice, r=compiler-errors
Emit error in `collecting_trait_impl_trait_tys` on mismatched signatures

Previously, a `delay_span_bug` was isssued, failing normalization. This create a `TyKind::Error` in the signature, which caused `compare_predicate_entailment` to swallow its signature mismatch error, causing ICEs because no error was emitted.

Remove lock wrappers in `sys_common`

This moves the lazy allocation to `sys` (SGX and UNIX). While this leads to a bit more verbosity, it will simplify future improvements by making room in `sys_common` for platform-independent implementations.

This also removes the condvar check on SGX as it is not necessary for soundness and will be removed anyway once mutex has been made movable.

For simplicity's sake, `libunwind` also uses lazy allocation now on SGX. This will require an update to the C definitions before merging this (CC `@raoulstrackx).`

Reduce default configuration's dependency upon static libstdcpp library (#103606)

Fixes #103606

Remove default dependency on static libstdcpp except during dist llvm builds (where we want static libraries so `libLLVM.so` is self-contained).

Rollup merge of #104217 - Nilstrieb:funny-dollar-syntax, r=TaKO8Ki
Display help message when fluent arg was referenced incorrectly

The fluent argument syntax is a little special and easy to get wrong, so we emit a small help message when someone gets it wrong.

Example:
```
parser_mismatched_closing_delimiter = mismatched closing delimiter: `${delimiter}`
```
panics with
```
thread 'rustc' panicked at 'Encountered errors while formatting message for `parser_mismatched_closing_delimiter`
help: Argument `delimiter` exists but was not referenced correctly. Try using `{$delimiter}` instead
attr: `None`
args: `FluentArgs([("delimiter", String("}"))])`
errors: `[ResolverError(Reference(Message { id: "delimiter", attribute: None }))]`', compiler/rustc_errors/src/translation.rs:123:21
```

Rollup merge of #104146 - Ayush1325:remote-test-server, r=jyn514
Retry binding TCP Socket in remote-test-server

This allows retrying binding TCP Socket multiple times. This is useful when using emulators as network might not be available in the beginning.

This was orignally implemented in https://github.com/rust-lang/rust/pull/100316

Fix broken link in description of error code E0706

Corresponding subsection in async book is `07.05` not `07.06`.

The information on the linked page is the same so it may be reasonable to remove the whole sentence.

Rollup merge of #103445 - fmease:fix-50291, r=estebank
`#[test]`: Point at return type if `Termination` bound is unsatisfied

Together with #103142 (already merged) this fully fixes #50291.

I don't consider my current solution of changing a few spans “here and there” very clean since the
failed obligation is a `FunctionArgumentObligation` and we point at a type instead of a function argument.

If you agree with me on this point, I can offer to keep the spans of the existing nodes and instead inject
`let _: AssertRetTyIsTermination<$ret_ty>;` (type to be defined in `libtest`) similar to `AssertParamIsEq` etc.
used by some built-in derive-macros.

I haven't tried that approach yet though and cannot promise that it would actually work out or
be “cleaner” for that matter.

Rollup merge of #100633 - estebank:must_use_async_fn_return, r=tmandry
Consider `#[must_use]` annotation on `async fn` as also affecting the `Future::Output`

No longer lint against `#[must_use] async fn foo()`.

When encountering a statement that awaits on a `Future`, check if the
`Future`'s parent item is annotated with `#[must_use]` and emit a lint
if so. This effectively makes `must_use` an annotation on the
`Future::Output` instead of only the `Future` itself.

Fix #78149.
