67d88f93cd Rollup merge of #147027 - GuillaumeGomez:tyalias-disambiguator, r=lolbinarycat 
Add new `tyalias` intra-doc link disambiguator

Fixes https://github.com/rust-lang/rust/issues/146855.

Alternative to rust-lang/rust#146866.

This adds support for a new disambiguator: `tyalias`. I think it's common enough to have type aliases nowaday, so no reason to not be able to have a disambiguator for them.

6b379b560d use try_structurally_resolve_type for method receiver 
We'll still error due to the `opt_bad_ty` of `method_autoderef_steps`.
This slightly worsens the span of `infer_var.method()` which is now the
same as for `Box::new(infer_var).method()`.

Unlike `structurally_resolve_type`, `probe_op` does not check whether
the infcx is already tainted, so this results in 2 previously not emitted
errors.

remove incorrect fast path

Using `tcx.is_copy_modulo_regions` drops information from the current `typing_env`. Writing a regression test for this is really hard. We need to prove `Copy` of something that doesn't directly reference a coroutine or an opaque, but does so indirectly.

rustdoc: hide `#[repr]` if it isn't part of the public ABI

> [!IMPORTANT]
> Temporarily stacked on top of PR https://github.com/rust-lang/rust/pull/146527; only the last commit is relevant!

Follow-up to rust-lang/rust#115439.
Unblocks rust-lang/rust#116743, CC ``@dtolnay.``

Fixes rust-lang/rust#66401.
Fixes rust-lang/rust#128364.
Fixes rust-lang/rust#137440.

Only display the representation `#[repr(REPR)]` (where `REPR` is not `Rust` or `transparent`) of a given type if none of its variants (incl. the synthetic variants of structs) are `#[doc(hidden)]` and all of its fields are public and not `#[doc(hidden)]` since it's likely not meant to be considered part of the public ABI otherwise.

`--document-{private,hidden}-items` works as expected in this context, too.

Moreover, we now also factor in the presence of `#[doc(hidden)]` when checking whether to show `repr(transparent)` or not.

46e25aa7a3 Rollup merge of #146766 - nikic:global-alloc-attr, r=nnethercote 
Add attributes for #[global_allocator] functions

Emit `#[rustc_allocator]` etc. attributes on the functions generated by the `#[global_allocator]` macro, which will emit LLVM attributes like `"alloc-family"`. If the module with the global allocator participates in LTO, this ensures that the attributes typically emitted on the allocator declarations are not lost if the definition is imported.

There is a similar issue when the allocator shim is used, but I've opted not to fix that case in this PR, because doing that cleanly is somewhat gnarly.

Do not materialise X in [X; 0] when X is unsizing a const

Fix rust-lang/rust#143671

It turns out that MIR builder materialise `X` in `[X; 0]` into a temporary local when `X` is unsizing a `const`. This led to a confusing call to destructor of `X` when such a destructor is declared. [Playground](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2024&gist=8dfc933af89efeb89c881bc77498ba63)

This patch may miss out other cases that we should avoid materialisation in case of `[X; 0]`. Suggestions to include is most welcome!
