Allow generators to impl Clone/Copy
Revives #95137. It's a pity that the original pr didn't land because the implementation is almost complete! All credits goes to `@canndrew,` and i just resolved the merge conflicts and updated the feature gate version number.

Add @obi1kenobi to the cc list for rustdoc-json-types
I'm one of the maintainers of `cargo-semver-checks`, and as mentioned [in Zulip](https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/Long.20Term.20Rustdoc.20JSON.20Stability) it's very useful to me to know about upcoming rustdoc JSON types changes so I can be ready to publish new `cargo-semver-checks` releases compatible with the new JSON format.
Auto merge of #101482 - joboet:netbsd_parker, r=sanxiyn
Optimize thread parking on NetBSD
As the futex syscall is not present in the latest stable release, NetBSD cannot use the efficient thread parker and locks Linux uses. Currently, it therefore relies on a pthread-based parker, consisting of a mutex and semaphore which protect a state variable. NetBSD however has more efficient syscalls available: [`_lwp_park`](https://man.netbsd.org/_lwp_park.2) and [`_lwp_unpark`](https://man.netbsd.org/_lwp_unpark.2). These already provide the exact semantics of `thread::park` and `Thread::unpark`, but work with thread ids. In `std`, this ID is here stored in an atomic state variable, which is also used to optimize cases were the parking token is already available at the time `thread::park` is called.
Currently the documentation of f64::min refers to "IEEE-754 2008" while the documentation of
f64::minimum refers to "IEEE 754-2019".
Note that one has the format IEEE,hyphen,number,space,year while the other is
IEEE,space,number,hyphen,year. The official IEEE site [1] uses the later format and it is also the
one most commonly used throughout the codebase.
Update all comments and - more importantly - documentation to consistently use the official format.
Auto merge of #101613 - GuillaumeGomez:codeblock-tooltip, r=notriddle
Simplify codeblock and their associated tooltip
It is based on https://github.com/rust-lang/rust/pull/101600 so it needs to wait for this one to be merged first.
This PR does two things:
* Remove CSS class duplication by setting CSS classes such as `compile_fail` directly on the `div` wrapping both the codeblock and the tooltip.
* Simplify DOM: no need to wrap the tooltip into a `<div>`, it can work just as well without it.
You can test it [here](https://rustdoc.crud.net/imperio/codeblock-tooltip/std/string/struct.String.html#deref).

If we just subtype the signatures `fn() -> &'static str <: fn() -> _#1t` (where `_#1t` is the variable we've used to infer `impl Sized`), we'll end up `&'static str <: _#1t`, which causes us to infer `_#1t = #'_#2r str`, where `'_#2r` is unconstrained, which gets fixed up to `ReEmpty`, and which is certainly not what we want.
I can't actually think of a way to make this fail to compile, because during borrowck we've already done the method probe, and so we just look at the `impl` method signature and see the `&'static str` any time we call `<() as Foo>::bar()`. But this _does_ cause the ICE [here](https://github.com/rust-lang/rust/pull/98559#issuecomment-1241891994) in `@jackh726's` "Remove ReEmpty" PR (#98559) to stop ICEing, because after that PR we were leaking unconstrained region variables into the typeck results.
To keep the layout looking the same, the links need to not have `width: 100%` any more, relying instead on the box naturally growing to fit because it has `display: block`.
Similar to rust-lang/rust#100445, this adapts the new test added by rust-lang/rust#99207 to some relatively recent [LLVM changes](https://github.com/llvm/llvm-project/commit/057cabd997aeaef136e1e14f2ee645bd5bb197dd) that removed the function name from msan messages.

Rollup merge of #101595 - ehuss:fix-ice-flag-report, r=tmiasko
Fix ICE report flags display.
#92310 made some changes to the ICE report that displays the rustc flags, but it introduced a bug where a flag like `-Z incremental-verify-ich=yes` was being treated as-if it was `-Cincremental`. This corrupted the output and made it confusing. The cause was using `starts_with` instead of properly splitting the option.
For example, with the command like `rustc foo.rs -Cincremental=/tmp/a -Zincremental-verify-ich=yes --crate-type lib` would previously look like:

Use RelocModel::Pic for UEFI targets
In https://github.com/rust-lang/rust/pull/100537, the relocation model for UEFI targets was changed from PIC (the default value) to

It turns out that this can cause compilation to fail as described in https://github.com/rust-lang/rust/issues/101377, so switch back to PIC.

Stabilize raw-dylib for non-x86
This stabilizes the `raw-dylib` and `link_ordinal` features (#58713) for non-x86 architectures (i.e., `x86_64`, `aarch64` and `thumbv7a`):
* Marked the `raw_dylib` feature as `active`.
* Marked the `link_ordinal` attribute as `ungated`.
* Added new errors if either feature is used on x86 targets without the `raw_dylib` feature being enabled.
* Updated tests to only set the `raw_dylib` feature when building for x86.

Fix the example code and doctest for Formatter::sign_plus
The provided example to the `sign_plus` method on `fmt` was broken, it displays the `-` sign twice for negative numbers.
This pull request should fix the issue by `.abs()` ing the number so that the negative sign appears only once. It is just one possible solution to the issue, not sure if it's the best. However, this one will behave as expected when combined with fill and alignment operators.

Restore old behaviour on broken UNC paths
This fixes #101358 by restoring the behaviour from previous stable Rust versions. I'm not convinced this is ultimately right but I think it's less wrong and maybe this should be backported to beta?
This PR moves the tooltip into example-wrap, simplifying several overly-complex aspects of how these tooltips work:
* The mousover javascript can be removed, because hovering example-wrap can style the tooltip inside.
* The sibling selecor can be removed, because hovering the tooltip also hovers the wrapper, which can hover the codeblock itself.
* The relative positioning of the `<li>` tag, which was added in https://github.com/rust-lang/rust/commit/e861efd9f9ca45c1048a256812dfe8faffbb1367 to fix the positioning of the code tooltip, can now be removed, because example-wrap itself already has relative positioning.
