This commit makes the `width` and `min-width` of the sidebar the same. They
originally were when cad0fce205 added the
`min-width` rule, but 6a5f8b1aef changed the
width without changing the `min-width`, causing it to sometimes oscilate
between 200 and 250 pixels depending on the main content.
Fix a typo in `std`'s root docs
Remarkably, this typo has been present for *seven years.* I was so surprised that I reread the text five times and then asked people on the rust Zulip to double-check. :)
add regression test for miri issue 2433
Adding this here because the test needs to be run with debug assertions enabled to be sure so I had to run it in the rustc workspace.

Detect panic strategy using `rustc --print cfg`
Instead of relying on a command line parameter, detect if a target is able to unwind or not.
Ignore tests that require unwinding on targets that don't support it.
I did not find any place where the removed parameter has been used, but it feels a bit risky as
I'm new to this test framework.

Add examples to `bool::then` and `bool::then_some`
Added examples to `bool::then` and `bool::then_some` to show the distinction between the eager evaluation of `bool::then_some` and the lazy evaluation of `bool::then`.
Introduce mir::Unevaluated
Previously the distinction between unevaluated constants in the type-system and in mir was not explicit and a little confusing. Probably better to introduce its own type for that.

Instead of relying on a command line parameter, detect if a target
is able to unwind or not.
Ignore tests that require unwinding on targets that don't support it.
There's a bunch of these checks because of special handing for ZSTs in various unsafe implementations of stuff.
This lets them be `T::IS_ZST` instead of `mem::size_of::<T>() == 0` every time, making them both more readable and more terse.
*Not* proposed for stabilization at this time. Would be `pub(crate)` except `alloc` wants to use it too.
(And while it doesn't matter now, if we ever get something like 85836 making it a const can help codegen be simpler.)
Improve the help message for an invalid calling convention
Fixes https://github.com/rust-lang/rust/issues/93601
I mostly followed the suggestions of `@nagisa` in that issue, ~~however, I wasn't sure how to check stability for the suggestion of "Do not suggest CCs that cannot be used due to them being unstable and feature not being enabled", so I did not implement that point.~~
I haven't contributed to rustc much, please feel free to point out suggestions! For example, the `.map(|s| Symbol::intern(s)).collect::<Vec<_>>()` seems pretty gross performance-wise, but maybe that's OK in error reporting code.
Allow full relro on powerpc64-unknown-linux-gnu
This was previously limited to partial relro, citing issues on RHEL6,
but that's no longer a supported platform since #95026. We have long
been enabling full relro in RHEL7's own Rust builds for ppc64, without
trouble, so it should be fine to drop this workaround.
rustdoc: remove unnecessary `max-width` on headers
This code was added in 003b2bc1c6 to prevent these headers from overlapping `.out-of-band` side items. That stopped being a problem when 3f92ff34b5 switched rustdoc over to using `float`, rather than `position: absolute`, to implement this.
Distribute rust-docs-json via rustup.
I am not 100% sure on how to treat `rust-json-docs` in `target_host_combination`. I went along with a similar strategy to the one used for `rust-docs`, but looking for guidance there.
Migrated the rustc_passes annotation without effect diagnostic infrastructure
Small change to move the validation for annotations to the new diagnostic infrastructure.
Note if mismatched types have a similar name
If users get a type error between similarly named types, it will point out that these are actually different types, and where they were defined.
Split out async_fn_in_trait into a separate feature
PR #101224 added support for async fn in trait desuraging behind the `return_position_impl_trait_in_trait` feature.
Split this out so that it's behind its own feature gate, since async fn in trait doesn't need to follow the same stabilization schedule.
