I encountered an instance where an `FnPtr` implemented a trait, but I was passing an `FnDef`. To
the end user, there is really no way to differentiate each of them, but it is necessary to cast
to the generic function in order to compile. It is thus useful to suggest `as` in the help note,
(even if the Fn output implements the trait).
Fix aarch64-unknown-linux-gnu_ilp32 target
This was broken because the synthetic object files produced by rustc were for 64-bit AArch64, which caused link failures when combined with 32-bit ILP32 object files.
This PR updates the object crate to 0.30.1 which adds support for generating ILP32 AArch64 object files.
Update mdbook
This updates mdbook from 0.4.21 to 0.4.25. The list of changes is [here](https://github.com/rust-lang/mdBook/blob/master/CHANGELOG.md#mdbook-0425). The only user-visible changes are some changes around the theme picker, and change to the copy-to-clipboard ignoring hidden lines.
Internally there were some dependency updates and small fixes.
This also updates `clap` from 4.0.15 to 4.0.32 whose changelog is [here](https://github.com/clap-rs/clap/blob/master/CHANGELOG.md#4032---2022-12-22). This impacts tools like cargo. I don't see anything particularly noteworthy there, though there are some small user-visible changes.
Unfortunately this required adding a hack for building `rustix` with a bootstrap tool. The comment explains why. I am unable to think of some other workaround (or even a cleaner way to set the rustflag). Ideas are welcome if you can think of alternatives. I'm struggling to even think of a long-term solution, other than asking projects not to do auto-nightly feature detection.
One medium-term solution is to avoid the clap dependency for the mdbook library (which is how rustix gets pulled in). That is one of my goals for the 0.5 release of mdbook, but that probably won't happen until later this year. It would also require dropping clap from `rustbook` and using some other means to parse arguments (there's only two options, so it can probably be done manually).
rustdoc: remove unnecessary DOM class `h1.fqn`
It's misleading. The main heading sometimes isn't an fully qualified name at all.
It's also redundant. It's always a child of `div.main-heading`, so just use that.
Update `rental` hack to work with remapped paths.
This PR simply switches to an already-existing helper instead of hard-coding a specific enum variant. The new revision of the test fails without the other changes in this PR.
Context: I'm exploring running UI tests with remapped paths by default in #105924 and the rental test was one of the ones that failed.
This may also be useful in the context of https://github.com/rust-lang/rfcs/pull/3127 ("New rustc and Cargo options to allow path sanitisation by default").
Remove duplicate sha-1 dependency
[`sha-1`](https://crates.io/crates/sha-1) is more or less a duplicate of [`sha1`](https://crates.io/crates/sha1). The `sha-1` is deprecated and no longer updated. This updates the dependencies to use the new name.
Some other dependencies that got updated as a consequence:
* The updated pest dependencies are currently only used by mdbook, and shouldn't have any issues.
* ucd-trie 0.1.3 to 0.1.5: No changelog, but looks like some tables were updated for new unicode versions: https://github.com/BurntSushi/ucd-generate/commits/master/ucd-trie. This is only used by pest (and thus mdbook).
* thiserror 1.33 to 1.38: Nothing significant in the notes at https://github.com/dtolnay/thiserror/releases.
rustdoc: rename CSS rustdoc-toggle -> toggle and toggle -> settings-toggle
This swaps things around so that the class that gets used more often has the shorter name.
mv binary_heap.rs binary_heap/mod.rs
I confess this request is somewhat selfish, as it's made in order to ease synchronisation with my [copse](https://crates.io/crates/copse) crate (see eggyal/copse#6 for explanation). I wholly understand that such grounds may be insufficient to justify merging this request—but no harm in asking, right?
reword Option::as_ref and Option::map examples
The description for the examples of `Option::as_ref` and `Option::map` imply that the example is only doing type conversion, when it is actually finding the length of a string.
Changes the wording to imply that some operation is being run on the value contained in the `Option`
closes#104476
This commit builds on b72de9be74, which removes
the `docblock` class from the All Items page, and
9457380ac9, which removes the `docblock` class
from the item decl.
Fixes#92974
This commit updates the wasi-libc revision used to build with the
wasm32-wasi target. This notably pulls in WebAssembly/wasi-libc#377
which is needed to fix a use case I've been working on recently. This
should be a relatively small update hopefully and is not expected to
have any user impact.
riscv: Fix ELF header flags
The previous version added both `EF_RISCV_FLOAT_ABI_DOUBLE` and `EF_RISCV_RVC` if the "D" extension was enabled on riscv64 targets. riscv32 targets were not accounted for. This patch changes this so that:
- Only add `EF_RISCV_RVC` if the "C" extension is enabled
- Add `EF_RISCV_FLOAT_ABI_SINGLE` if the "F" extension is enabled and the "D" extension is not
- Add these ELF flags for riscv32 as well

Normalize test output more thoroughly
This prevents differences in local environments, which may (for example) end up with a longer backtrace with more digits in the backtrace prefix, as happened to me. While we're at it, clean more of the output up, including the exact location of the error in the compiler.

Warn when using panic-strategy abort for proc-macro crates
See https://github.com/rust-lang/rust/issues/82320, this simply warns for now as that seems like the best step that can be immediately taken (opposed to straight up rejecting or ignoring)
Fix linker detection for linker (drivers) with a version postfix (e.g. clang-12 instead of clang)
Linker (drivers) such as clang / gcc or lld often have a version postfix matching the regex "-\d+$".
Previously, linker detection did not account for the possible version postfix and the fallback value was used, which can cause linker errors due to wrong arguments.
Also remove the check for `-clang`, since there are no architecture specific variants of clang (to my knowledge).

Bump `IMPLIED_BOUNDS_ENTAILMENT` to Deny + ReportNow
https://github.com/rust-lang/rust/pull/105575#issuecomment-1357201969
