Rollup merge of #99700 - est31:rustdoc_layout_heading, r=GuillaumeGomez
Add a clickable link to the layout section
The layout section (activated by `--show-type-layout`) is currently not linkable to (outside of chrome's link to text feature). This PR makes it linkable via `#layout`.
Rollup merge of #99698 - compiler-errors:no-doc-hidden, r=cjgillot
Prefer visibility map parents that are not `doc(hidden)` first
Far simpler approach to #98876.
This only fixes the case where the parent is `doc(hidden)`, not where the child is `doc(hidden)` since I don't know how to get the attrs on the import statement given a `ModChild`... I'll try to follow up with that, but this is a good first step.
Rollup merge of #98583 - joshtriplett:stabilize-windows-symlink-types, r=thomcc
Stabilize Windows `FileTypeExt` with `is_symlink_dir` and `is_symlink_file`
These calls allow detecting whether a symlink is a file or a directory,
a distinction Windows maintains, and one important to software that
wants to do further operations on the symlink (e.g. removing it).
On znver2 the default impl seems to be slow due to different inlining decisions. It goes through `core::array::iter_next_chunk`
which has a deep call tree.

codegen: use new {re,de,}allocator annotations in llvm
This obviates the patch that teaches LLVM internals about
_rust_{re,de}alloc functions by putting annotations directly in the IR
for the optimizer.
The sole test change is required to anchor FileCheck to the body of the
`box_uninitialized` method, so it doesn't see the `allocalign` on
`__rust_alloc` and get mad about the string `alloca` showing up. Since I
was there anyway, I added some checks on the attributes to prove the
right attributes got set.
Rollup merge of #99724 - ehuss:fix-broken-links-fragment, r=Dylan-DPC
Fix some broken link fragments.
An exception for link fragments starting with `-` was added in #49590. However, it is not clear what issues were encountered at the time. Perhaps those were fixed in the meantime.
This removes the exception, and fixes a couple of broken links that were skipped due to it.

rustdoc: Add support for `#[rustc_must_implement_one_of]`
This PR adds support for `#[rustc_must_implement_one_of]` attribute added in #92164. There is a desire to eventually use this attribute of `Read`, so making it show up in docs is a good thing.
I "stole" the styling from cfg notes, not sure what would be a proper styling. Currently it looks like this:

While we're here, we also emit allocator attributes on
__rust_alloc_zeroed. This should allow LLVM to perform more
optimizations for zeroed blocks, and probably fixes #90032. [This
comment](https://github.com/rust-lang/rust/issues/24194#issuecomment-308791157)
mentions "weird UB-like behaviour with bitvec iterators in
rustc_data_structures" so we may need to back this change out if things
go wrong.
The new test cases require LLVM 15, so we copy them into LLVM
14-supporting versions, which we can delete when we drop LLVM 14.

Rewrite Windows `compat_fn` macro
This allows using most delay loaded functions before the init code initializes them. It also only preloads a select few functions, rather than all functions.

interpret, ptr_offset_from: refactor and test too-far-apart check
We didn't have any tests for the "too far apart" message, and indeed that check mostly relied on the in-bounds check and was otherwise probably not entirely correct... so I rewrote that check, and it is before the in-bounds check so we can test it separately.
Rollup merge of #99666 - compiler-errors:issue-99663, r=lcnr
Restore `Opaque` behavior to coherence check
Fixes #99663.
This broke in 84c3fcd2a0285c06a682c9b064640084e4c7271b. I'm not exactly certain that adding this behavior back is necessarily correct, but at least the UI test I provided may stimulate some thoughts.
I think delaying a bug here is certainly not correct in the case of opaques -- if we want to change coherence behavior for opaques, then we should at least be emitting a new error.

handle consts with param/infer in `const_eval_resolve` better
This PR addresses [this thread here](https://github.com/rust-lang/rust/pull/99449#discussion_r924141230). Was this the change you were looking for ``@lcnr?``
Interestingly, one test has begun to pass. Was that expected?
Also downmaps tokens inside deriver helpers to the derive expansion
This does not handle the case where multiple derives make use of the same helper name though, unsure how to tackle that yet.

Remove new allocations from `imported_source_files`
https://github.com/rust-lang/rust/pull/97786 introduced a [large performance regression](https://github.com/rust-lang/rust/pull/97786#issuecomment-1176552836). After some local investigation it turns out the allocations performed by my change were the cause of the perf regression. This PR refactors my change to remove those allocations.
Auto merge of #12858 - fasterthanlime:proc-macro-srv-bin, r=Veykril
Add `rust-analyzer-proc-macro-srv` binary, use it if found in sysroot
This adds a `bin` crate which simply runs `proc_macro_srv::cli::run()` (it does no CLI argument parsing, nothing).
The intent is to build that crate in Rust CI as part of the `dist::Rustc` component, then ship it in the sysroot: it would probably land in something like `~/.rustup/toolchains/nightly-2022-07-23-x86_64-unknown-linux-gnu/libexec/proc-macro-srv-cli`.
This makes https://github.com/rust-lang/rustup/pull/3022 less pressing. (Instead of teaching RA about rustup components, we simply teach it to look in the sysroot via `rustc --print sysroot`. If it can't find `proc-macro-srv-cli`, it falls back to its own `proc-macro` subcommand).
This is closely related to https://github.com/rust-lang/rust-analyzer/issues/12803 (but doesn't close it yet).
Things to address now:
* [ ] What should the binary be named? What should the crate be named? We can pick different names with `[bin]` in the `Cargo.toml`
Things to address later:
* Disable the "multi ABI compatibility scheme" when building that binary in Rust CI (that'll probably happen in `rust-lang/rust`)
* Teaching RA to look in the sysroot
Things to address much, much later:
* Is JSON a good fit here
* Do we want to add versioning to future-proof it?
* Other bikesheds
When built with `--features sysroot` on `nightly-2022-07-23-x86_64-unknown-linux-gnu`, the binary is 7.4MB. After stripping debuginfo, it's 2.6MB. When compressed to `.tar.xz`, it's 619KB.
In a Zulip discussion, `@jyn514` and `@Mark-Simulacrum` seemed to think that those sizes weren't a stopper for including the binary in the rustc component, even before we shrink it down further.

Remove reachable coverage without counters
Remove reachable coverage without counters to maintain invariant that
either there is no coverage at all or there is a live coverage counter
left that provides the function source hash.
The motivating example would be a following closure:
```rust
let f = |x: bool| {
debug_assert!(x);
};
```
Which, with span changes from #93967, with disabled debug assertions,
after the final CFG simplifications but before removal of dead blocks,
gives rise to MIR:
```rust
fn main::{closure#0}(_1: &[closure@a.rs:2:13: 2:22], _2: bool) -> () {
debug x => _2;
let mut _0: ();

Remove some explicit `self.infcx` for `FnCtxt`, which already derefs into `InferCtxt`
The use of `self.infcx.method_on_infcx` vs `self.method_on_infcx` when `self` is a `FnCtxt` is a bit inconsistent, so I'm moving some `self.infcx` usages I found to just use autoderef
Rollup merge of #99353 - compiler-errors:gat-where-clause-mismatch, r=cjgillot
Slightly improve mismatched GAT where clause error
This makes the error reporting a bit more standardized between `where` on GATs and functions.
cc #99206 (`@BoxyUwU),` don't want to mark this as as "fixed" because they're still not perfect, but this is still an improvement IMO so I want to land it incrementally.
regarding "consider adding where clause to trait definition", we don't actually do that for methods as far as i can tell? i could file an issue to look into that maybe.
Auto merge of #98989 - dpaoliello:rawdylibbin, r=michaelwoerister
Enable raw-dylib for bin crates
Fixes #93842
When `raw-dylib` is used in a `bin` crate, we need to collect all of the `raw-dylib` functions, generate the import library and add that to the linker command line.
I also changed the tests so that 1) the C++ dlls are created after the Rust dlls, thus there is no chance of accidentally using them in the Rust linking process and 2) disabled generating import libraries when building with MSVC.
