2024-10-25Emit error when calling/declaring functions with unavailable vectors.Luca Versari-53/+448
On some architectures, vector types may have a different ABI when relevant target features are enabled. As discussed in https://github.com/rust-lang/lang-team/issues/235, this turns out to very easily lead to unsound code. This commit makes it an error to declare or call functions using those vector types in a context in which the corresponding target features are disabled, if using an ABI for which the difference is relevant.

Try to improve error messages involving aliases in the solver 1. Treat aliases as rigid only if it may not be defined and it's well formed (i.e. for projections, its trait goal is satisfied). 2. Record goals that are related to alias normalization under a new `GoalKind`, so we can look into them in the `BestObligation` visitor. 3. Try to deduplicate errors due to self types of goals that are un-normalizable aliases. r? lcnr

Implement edition 2024 match ergonomics restrictions This implements the minimalest version of [match ergonomics for edition 2024](https://rust-lang.github.io/rfcs/3627-match-ergonomics-2024.html). This minimal version makes it an error to ever reset the default binding mode. The implemented proposal is described precisely [here](https://hackmd.io/zUqs2ISNQ0Wrnxsa9nhD0Q#RFC-3627-nano), where it is called "RFC 3627-nano". Rules: - Rule 1C: When the DBM (default binding mode) is not `move` (whether or not behind a reference), writing `mut`, `ref`, or `ref mut` on a binding is an error. - Rule 2C: Reference patterns can only match against references in the scrutinee when the DBM is `move`. This minimal version is forward-compatible with the main proposals for match ergonomics 2024: [RFC3627](https://rust-lang.github.io/rfcs/3627-match-ergonomics-2024.html) itself, the alternative [rule 4-early variant](https://rust-lang.github.io/rfcs/3627-match-ergonomics-2024.html), and [others](https://hackmd.io/zUqs2ISNQ0Wrnxsa9nhD0Q). The idea is to give us more time to iron out a final proposal. This includes a migration lint that desugars any offending pattern into one that doesn't make use of match ergonomics. Such patterns have identical meaning across editions. This PR insta-stabilizes the proposed behavior onto edition 2024. r? `@ghost` Tracking: - https://github.com/rust-lang/rust/issues/123076

Add `from_ref` and `from_mut` constructors to `core::ptr::NonNull`. Relevant tracking issue: #130823 The `core::ptr::NonNull` type should have the convenience constructors `from_ref` and `from_mut` for parity with `core::ptr::from_ref` and `core::ptr::from_mut`. Although the type in question already implements `From<&T>` and `From<&mut T>`, these new functions also carry the ability to be used in constant expressions (due to not being behind a trait).

Fix unnecessary nesting in run-make test output directories Run-make tests were using `output_base_name` to determine their output directory, which results in a redundant subdirectory (e.g. `$build/test/run-make/<foo>/<foo>/`) because that method is intended to produce the name of an individual file. The previous attempt to fix this double-nesting tried adding a special case in `output_base_dir`, which had the side-effect of breaking up-to-date checking for run-make tests, and had to be reverted in #131681. The fix is simply to call `output_base_dir` directory, which gives the desired directory without any redundant part. r? jieyouxu

Don't report bivariance error when nesting a struct with field errors into another struct We currently have logic to avoid reporting lifetime bivariance ("lifetime parameter ... is never used") errors when a struct has field resolution errors. However, this doesn't apply transitively. This PR implements a simple visitor to do so. This was reported [here](https://twitter.com/fasterthanlime/status/1846257921086165033) since a `derive(Deserialize, Serialize)` ends up generating helper structs which have bivariant lifetimes due to containing the offending struct (that's being derived on).

Relax a memory order in `once_box` per https://github.com/rust-lang/rust/pull/131094#discussion_r1788536445. In the successful path we don't need `Acquire` since we don't care if the store in `f()` happened in other threads has become visible to the current thread. We'll use our own results instead and just using `Release` to ensure other threads can see our store to `Box` when they fail the `compare_exchange` will suffice.

Remove `GenKillAnalysis` There are two kinds of dataflow analysis in the compiler: `Analysis`, which is the basic kind, and `GenKillAnalysis`, which is a more specialized kind for gen/kill analyses that is intended as an optimization. However, it turns out that `GenKillAnalysis` is actually a pessimization! It's faster (and much simpler) to do all the gen/kill analyses via `Analysis`. This lets us remove `GenKillAnalysis`, and `GenKillSet`, and a few other things, and also merge `AnalysisDomain` into `Analysis`. The PR removes 500 lines of code and improves performance. r? `@tmiasko`

Optimize `Box::default` and `Arc::default` to construct more types in place Both the `Arc` and `Box` `Default` impls currently call `T::default()` before allocating, and then moving the resulting `T` into the allocation. Most `Default` impls are trivial, which should in theory allow LLVM to construct `T: Default` directly in the `Box` allocation when calling `<Box<T>>::default()`. However, the allocation may fail, which necessitates calling `T`'s destructor if it has one. If the destructor is non-trivial, then LLVM has a hard time proving that it's sound to elide, which makes it construct `T` on the stack first, and then copy it into the allocation. Change both of these impls to allocate first, and then call `T::default` into the uninitialized allocation, so that LLVM doesn't have to prove that it's sound to elide the destructor/initial stack copy. For example, given the following Rust code: ```rust #[derive(Default, Clone)] struct Foo { x: Vec<u8>, z: String, y: Vec<u8>, } #[no_mangle] pub fn src() -> Box<Foo> { Box::default() } ``` <details open> <summary>Before this PR:</summary> ```llvm `@__rust_no_alloc_shim_is_unstable` = external global i8 ;

2024-10-16Auto merge of #131422 - GnomedDev:smallvec-predicate-obligations, ↵bors-255/+414
r=compiler-errors Use `ThinVec` for PredicateObligation storage ~~I noticed while profiling clippy on a project that a large amount of time is being spent allocating `Vec`s for `PredicateObligation`, and the `Vec`s are often quite small. This is an attempt to optimise this by using SmallVec to avoid heap allocations for these common small Vecs.~~ This PR turns all the `Vec<PredicateObligation>` into a single type alias while avoiding referring to `Vec` around it, then swaps the type over to `ThinVec<PredicateObligation>` and fixes the fallout. This also contains an implementation of `ThinVec::extract_if`, copied from `Vec::extract_if` and currently being upstreamed to https://github.com/Gankra/thin-vec/pull/66. This leads to a small (0.2-0.7%) performance gain in the latest perf run.
