Add MVP suggestion for `unsafe_op_in_unsafe_fn`
Rebase of https://github.com/rust-lang/rust/pull/99827
cc tracking issue https://github.com/rust-lang/rust/issues/71668
No real changes since the original PR, just migrated the new suggestion to use fluent messages and added a couple more testcases, AFAICT from the discussion there were no outstanding changes requested.
Adjust UI tests for `unit_bindings` lint
- Explicitly annotate `let x: () = expr;` where `x` has unit type, or remove the unit binding to leave only `expr;` instead.
- Use `let () = init;` or `let pat = ();` where appropriate.
- Fix disjoint-capture-in-same-closure test which wasn't actually testing a closure: `tests/ui/closures/2229_closure_analysis/run_pass/disjoint-capture-in-same-closure.rs`.
Note that unfortunately there's *a lot* of UI tests, there are a couple of places where I may have left something like `let (): ()` (this is not needed but is left over from an ealier version of the lint) which is bad style.
This PR is to help with the `unit_bindings` lint at #112380.
It fixes the following error:
error[E0412]: cannot find type `sockcred2` in module `libc`
--> library/std/src/os/unix/net/ancillary.rs:211:29

internal: Record file dependencies in crate graph construction
Should fix the bug mentioned in https://github.com/rust-lang/rust-analyzer/issues/8623 where removing a crate root file will panic. I'm not too happy with the way this is done here but I can't think of a better way right now.
Deduplicate tuple indices for completion
Follow-up to #15026
A tuple struct may dereference to a primitive tuple (though unusual, which is why I previously overlooked this case). We should not show the same tuple index in completion in such cases.
Deduplication of indices among multiple tuple structs is already handled in the previous PR.
loongarch64-unknown-none*: Set default relocation model to static
This PR sets the default relocation model to `static` for `loongarch64-unknown-none*` targets. This change aims to streamline the development of the bare-metal project by removing the need for the executable program loader to implement relocation.
Make BinaryHeap parametric over Allocator
Tracking issue: #32838
Related: https://github.com/rust-lang/wg-allocators/issues/7
This parametrizes `BinaryHeap` with `A`, similarly to how other collections are parametrized.
A couple things I left out:
```
BinaryHeap::append
Currently requires both structures to have the same allocator type. Could
change, but depends on Vec::append, which has the same constraints.
impl<T: Ord> Default for BinaryHeap<T>
Not parametrized, because there's nowhere to conjure the allocator from.
impl<T: Ord> FromIterator<T> for BinaryHeap<T>
Not parametrized, because there's nowhere to conjure the allocator from.
impl<T: Ord, const N: usize> From<[T; N]> for BinaryHeap<T>
Not parametrized, because there's nowhere to conjure the allocator from.
unsafe impl<I> AsVecIntoIter for IntoIter<I>
AsVecIntoIter is not allocator aware, and I didn't dare change it without guidance. Is this something important?
```
I've seen very few tests for allocator_api in general, but I'd like to at least test this on some usage code in my projects before moving forward.
EDIT: Updated the list of impls and functions that are not affected by this. `BinaryHeap` no longer has a `SpecExtend` impl, and prior work made implementing `Extend` possible.
This feature extends rustdoc to support the syntax that most users will
naturally attempt to use to search for diverging functions.
Part of #60485
It's already possible to do this search with `primitive:never`, but
that's not what the Rust language itself uses, so nobody will try it if
they aren't told or helped along.
- Create `Answer` type that is not just a type alias of `Result`
- Remove a usage of `map_layouts` to make the code easier to read
- Don't hide errors related to Unknown Layout when computing transmutability
