8783766215 Hopefully fix rustdoc build
It's super unclear why this broke when we switched to beta but not
previously -- but at least it's hopefully fixed now.

Add hooks for Miri panic unwinding

This commits adds in some additional hooks to allow Miri to properly
handle panic unwinding. None of this should have any impact on CTFE mode

Fix MIR lowering evaluation order and soundness bug

f696b21c5f Move self-profile infrastructure to data structures
The single dependency on queries (QueryName) can be fairly easily
abstracted via a trait and this further decouples Session from librustc
(the primary goal).

Tiny cleanup to size assertions

The need to write `#[cfg(target_arch = "x86_64")]` twice mildly annoys me, the full paths look better in comparison.

Rollup merge of #66299 - rossmacarthur:fix-41260-avoid-issue-0, r=varkor
support issue = "none" in unstable attributes

This works towards fixing #41260.

This PR allows the use of `issue = "none"` in unstable attributes and makes changes to internally store the issue number as an `Option<NonZeroU32>`. For example:

```rust
#[unstable(feature = "unstable_test_feature", issue = "none")]
fn unstable_issue_none() {}
```

It was not made optional because feedback seen here #60860 suggested that people might forget the issue field if it was optional.

I could not remove the current uses of `issue = "0"` (of which there are a lot) because the stage 0 compiler expects the old syntax. Once this is available in the stage 0 compiler we can replace all uses of `"0"` with `"none"` and no longer allow `"0"`. This is my first time contributing, so I'm not sure what the protocol is with two-part things like this, so some guidance would be appreciated.

Rollup merge of #66280 - stepancheg:union, r=alexcrichton
Fix HashSet::union performance

Consider this example: small_set = 0..2, large_set = 0..1000.

To efficiently compute the union of these sets, we should
* take all elements of the larger set
* for each element of the smaller set check it is not in the larger set

This is exactly what this commit does.

This particular optimization was implemented a year ago, but the
author mistaken `<` and `>`.

Rollup merge of #66257 - mati865:long-section-names-no-more, r=alexcrichton
Drop long-section-names linker workaround for windows-gnu

If we can trust objdump Rust doesn't emit sections loaded at runtime longer than 8 characters on windows-gnu (but still does on linux-gnu), debug sections are not affected by that limit.
I've ran tests and built few crates using exactly the same mingw-w64 version as Rusts CI just fine using **x86_64** toolchain.

The motivation for this change is making LLD work (it doesn't support `--enable-long-section-names`) with this target without hacks.

Bit of history:
The behaviour of LD changed in Binutils 2.20 released on 2009-10-16 and `--enable-long-section-names` was added to return to the old non conformant behaviour. Looking at the comment I can only guess there was a bug fixed in newer versions.

This workaround was added in https://github.com/rust-lang/rust/pull/13315 half a decade ago.

remove vestigial comments referring to defunct numeric trait hierarchy

I've been poking around the numeric trait hierarchy and also some of the actual numeric type implementations.

This is a small change but a matter of effective communication.  I looked for other related references and saw none.

e3d998492a Auto merge of #66129 - Nadrieril:refactor-slice-pat-usefulness, r=varkor
Refactor slice pattern usefulness checking

As a follow up to https://github.com/rust-lang/rust/pull/65874, this PR changes how variable-length slice patterns are handled in usefulness checking. The objectives are: cleaning up that code to make it easier to understand, and paving the way to handling fixed-length slices more cleverly too, for https://github.com/rust-lang/rust/issues/53820.

Before this, variable-length slice patterns were eagerly expanded into a union of fixed-length slices. Now they have their own special constructor, which allows expanding them a bit more lazily.
As a nice side-effect, this improves diagnostics.

This PR shows a slight performance improvement, mostly due to 149792b608. This will probably have to be reverted in some way when we implement or-patterns.

1aee3e4d08 Use a relative bindir for rustdoc to find rustc
In bootstrap, we set `RUSTC_INSTALL_BINDIR` to `config.bindir`, so
rustdoc can find rustc relative to the toolchain sysroot. However, if a
distro script like Fedora's `%configure` sets an absolute path, then
rustdoc's `sysroot.join(bin_path)` ignores that sysroot altogether.

That would be OK once the toolchain is actually installed, but it breaks
the in-tree doc tests during the build, since `/usr/bin/rustc` is still
the old version. So now we try to make `RUSTC_INSTALL_BINDIR` relative
to the sysroot prefix in the first place.
