This updates the reference which is now using a new mdbook plugin. This
requires a little extra work than a normal book because the plugin uses
`rustdoc` to generate links to the standard library. It also ensures
that the submodule is available for *any* command that uses rustbook,
since it is now part of the rustbook workspace.
|
|
If the submodule is not checked out, then these tests would fail.
|
|
|
|
This adds a new method `require_and_update_submodule` to replace
`update_submodule`. This new method will generate an error if the
submodule doesn't actually exist. This replaces some ad-hoc checks that
were performing this function. This helps ensure that a good error
message is always displayed.
This also adds require_and_update_all_submodules which does this for
all submodules.
Ideally this should not have any change other than better error messages
when submodules are missing.
|
|
I put this submodule update in the entirely wrong location. I put it in
the `RustcBook` step (for generating src/doc/rustc), when it really
should exist for all steps that use the `Rustbook` tool.
|
|
Although its origins were in bootstrap.py, that code in bootstrap.py
no longer exists since it was removed.
|
|
The argument was not necessary, since it was only ever passed one
value that exists in the config itself.
|
|
This felt like an important point to me.
|
|
This is not used anywhere outside this module.
|
|
bootstrap.py handling of submodules was removed in
https://github.com/rust-lang/rust/pull/97513.

Reorder trait bound modifiers *after* `for<...>` binder in trait bounds
This PR suggests changing the grammar of trait bounds from:
```
[CONSTNESS] [ASYNCNESS] [?] [BINDER] [TRAIT_PATH]
const async ? for<'a> Sized
```
to
```
([BINDER] [CONSTNESS] [ASYNCNESS] | [?]) [TRAIT_PATH]
```
i.e., either
```
? Sized
```
or
```
for<'a> const async Sized
```
(but not both)
### Why?
I think it's strange that the binder applies "more tightly" than the `?` trait polarity. This becomes even weirder when considering that we (or at least, I) want to have `async` trait bounds expressed like:
```
where T: for<'a> async Fn(&'a ()) -> i32,
```
and not:
```
where T: async for<'a> Fn(&'a ()) -> i32,
```
### Fallout
No crates on crater use this syntax, presumably because it's literally useless. This will require modifying the reference grammar, though.
### Alternatives
If this is not desirable, then we can alternatively keep parsing `for<'a>` after the `?` but deprecate it with either an FCW (or an immediate hard error), and begin parsing `for<'a>` *before* the `?`.

rustdoc: clean up and fix ord violations in item sorting
Based on https://github.com/rust-lang/rust/pull/128139 with a few minor changes:
- The name sorting function is changed to follow the [version sort] from the style guide
- the `cmp` function is redesigned to more obviously make a partial order, by always return `cmp()` of the same variable as the `!=` above
[version sort]: https://doc.rust-lang.org/nightly/style-guide/index.html#sorting

Make ast `MutVisitor` have the same method name and style as `Visitor`

Allow to pass a full path for `run-make` tests
It's common (at least for me) to pass a full path to a `run-make` test (including the `rmake.rs` file) and to see that it isn't found, which is a bit frustrating.
With these changes, we can now optionally pass the `rmake.rs` (or even `Makefile`) at the end of the path.

Replace askama with rinja
Another askama maintainer and myself forked it and named the fork rinja. The whole difference is explained in this [blog post](https://blog.guillaume-gomez.fr/articles/2024-07-16+docs.rs+switching+jinja+template+framework+from+tera+to+rinja) (not publicly released yet, waiting for docs.rs to deploy the new version using it before). But in short, rinja got a lot of improvements and compiles faster, so I think it's definitely worth it to use it in rustdoc as well.

workingjubilee:weaken-thir-unsafeck-for-addr-of-static-mut, r=compiler-errors
treat `&raw (const|mut) UNSAFE_STATIC` implied deref as safe
Fixes rust-lang/rust#125833
As reported in that and related issues, `static mut STATIC_MUT: T` is very often used in embedded code, and is in many ways equivalent to `static STATIC_CELL: SyncUnsafeCell<T>`. The Rust expression of `&raw mut STATIC_MUT` and `SyncUnsafeCell::get(&STATIC_CELL)` are approximately equal, and both evaluate to `*mut T`. The library function is safe because it has *declared itself* to be safe. However, the raw ref operator is unsafe because all uses of `static mut` are considered unsafe, even though the static's value is not used by this expression (unlike, for example, `&STATIC_MUT`).
We can fix this unnatural difference by simply adding the proper exclusion for the safety check inside the THIR unsafeck, so that we do not declare it unsafe if it is not.
While the primary concern here is `static mut`, this change is made for all instances of an "unsafe static", which includes a static declared inside `extern "abi" {}`. Hypothetically, we could go as far as generalizing this to all instances of `&raw (const|mut) *ptr`, but today we do not, as we have not actually considered the range of possible expressions that use a similar encoding. We do not even extend this to thread-local equivalents, because they have less clear semantics.

Add NuttX based targets for RISC-V and ARM
Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. It is scalable from 8-bit to 64-bit microcontroller environments. The primary governing standards in NuttX are POSIX and ANSI standards.
NuttX adopts additional standard APIs from Unix and other common RTOSs, such as VxWorks. These APIs are used for functionality not available under the POSIX and ANSI standards. However, some APIs, like fork(), are not appropriate for deeply-embedded environments and are not implemented in NuttX.
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
I'll be adding libstd support for NuttX in the future, but for now I'll just add the targets.
Tier 3 policy:
> 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.)
I will be the target maintainer for this target on matters that pertain to the NuttX part of the triple. For matters pertaining to the riscv or arm part of the triple, there should be no difference from all other targets. If there are issues, I will address issues regarding the target.
> 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.
This is a new supported OS, so I have taken the origin target like `riscv32imac-unknown-none-elf` or `thumbv7m-none-eabi` and changed the `os` section to `nuttx`.
> 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.
I feel that the target name does not introduce any ambiguity.
> 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

The only unusual requirement for building the compiler-builtins crate is a standard RISC-V or ARM C compiler supported by cc-rs, and using this target does not require any additional software beyond what is shipped by rustup.
> The target must not introduce license incompatibilities.
All of the additional code will use Apache-2.0.
> Anything added to the Rust repository must be under the standard Rust
> license (`MIT OR Apache-2.0`).
Agreed, and there is no problem here.
> 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

No new dependencies are added.

There are no terms. NuttX is distributed under the Apache 2.0 license.

I'm not the reviewer here.

Again I'm not the reviewer here.

Building is described in platform support doc, but libstd is not supported now, I'll implement it later.

Yes, it use standard RISCV or ARM backend to generate assembly.
