2025-08-27Auto merge of #140737 - amandasystems:revised-constraint-search, r=lcnrbors-28/+25
Region inference: Use outlives-static constraints in constraint search Revise the extra `r: 'static` constraints added upon universe issues to add an explanation, and use that explanation during constraint blame search. This greatly simplifies the region inference logic, which now does not need to reverse-engineer the event that caused a region to outlive `'static`. This cosmetically changes the output of two UI tests. I blessed them i separate commits with separate motivations, but that can of course be squashed as desired. We probably want that. The PR was extracted out of rust-lang/rust#130227 and consists of one-third of its functional payload. r? lcnr

2025-08-27Auto merge of #144841 - cjgillot:typeck-no-attrs, r=davidtwcobors-0/+27
Access less HIR attributes from typeck Typeck relies on attributes to modify its own behaviour. This is a problem, as this means that `typeck(some function)` may depend on the span and doc-comments of many other functions. This PR attempts to reduce such accesses to attributes. This yields to a sizeable perf improvement: https://github.com/rust-lang/rust/pull/144841#issuecomment-3153339771 Fixes https://github.com/rust-lang/rust/issues/124352

2025-08-26Rollup merge of #144499 - Enselic:ci-debuginfo-level-tests, r=davidtwcoSamuel Tardieu-3/+19
ci: Begin running ui tests with `rust.debuginfo-level-tests=1` To reduce risk of regressing on generating debuginfo e.g. in the form of ICE:s. This will also ensure that future ui tests work with different debuginfo levels. See https://github.com/rust-lang/rust/issues/61117. When I looked at run time for different CI jobs, **x86_64-gnu-debug** was far from the bottleneck, so it should be fine to make it perform more work. A handful of tests are failing so we need to force debuginfo=0 on those for now. We'll start small with debuginfo=1. We'll step up to debuginfo=2 once most (all?) tests can handle debuginfo=1. There are more failures with debuginfo=2 than with debuginfo=1.

Implement some more checks in `ptr_guaranteed_cmp`. * Pointers with different residues modulo their allocations' least common alignment are never equal. * Pointers to the same static allocation are equal if and only if they have the same offset. * Pointers to different non-zero-sized static allocations are unequal if both point within their allocation, and not on opposite ends. Tracking issue for `const_raw_ptr_comparison`: <https://github.com/rust-lang/rust/issues/53020> This should not affect `is_null`, the only usage of this intrinsic on stable.

2025-08-25Auto merge of #145711 - lcnr:non-defining-uses-hir-typeck, r=BoxyUwUbors-183/+225
Support non-defining uses in HIR typeck This changes the impl of `NormalizesTo` for opaque types to be structural during HIR typeck. The previous impl equated region variables of the opaque type key with existing entries which can result in spurious leak check errors and also results in mismatches with MIR borrowck, theoretically causing ICE. The approach is very similar to rust-lang/rust#145244 in MIR typeck: - we collect all uses of opaque types during HIR typeck - before writeback, we search for *defining uses* - the opaque type key has fully universal generic args modulo regions - the hidden type has no infer vars - we use these defining uses to compute the concrete type for the opaque and map it to the definition site - we use this concrete type to check the type of all uses of opaques during HIR typeck. This also constrains infer vars in non-defining uses Fixes https://github.com/rust-lang/trait-system-refactor-initiative/issues/135, fixes https://github.com/rust-lang/trait-system-refactor-initiative/issues/49. r? `@BoxyUwU`

2025-08-25Rollup merge of #145620 - compiler-errors:fake-dyn-to-dyn, r=lcnrStuart Cook-0/+16
Account for impossible bounds making seemingly unsatisfyable dyn-to-dyn casts Fixes https://github.com/rust-lang/rust/issues/141806 When we have an impossible where clause like `dyn Trait<u8>: Sized`, this may make a dyn-to-dyn cast like `dyn Trait<()> -> dyn trait<u8>` to successfully type check as if it were a wide-to-thin ptr cast (discarding metadata): https://github.com/rust-lang/rust/blob/16ad385579cebb6f7d53367c552661b6b51a4a02/compiler/rustc_hir_typeck/src/cast.rs#L862-L865 In borrowck, we are expecting that the only meaningful dyn-to-dyn cast to be a metadata-preserving wide-to-wide ptr cast, which requires that the principals of the dyn pointers are equal. Borrowck additionally assumes that these principals have already been proven equal *modulo regions*, and we thus ICE since `Trait<u8>` and `Trait<()>` do not unify: https://github.com/rust-lang/rust/blob/16ad385579cebb6f7d53367c552661b6b51a4a02/compiler/rustc_borrowck/src/type_check/mod.rs#L1481-L1524 This PR fixes this ICE by checking whether the RHS of the cast is considered to be Sized in the environment of the MIR typeck, and if so then skipping over this dyn->dyn principal compatibility check. r? `@lcnr` perhaps?

Add more tests for the parallel rustc At the moment, the parallel frontend test cases are severely lacking. Althought some reported issues have been resolved, they haven't been added into the tests. This PR arranges the resolved ICE issues and adds tests for them. Whether it is worthwhile to add a separate test suite for the paralel frontend still requires futher discussion. But we are trying coveraging issues being resolved through capability of the existing UI test suite.

2025-08-23Rollup merge of #145798 - compiler-errors:unnamed-lt-primary, r=lqdJacob Pratt-119/+116
Use unnamed lifetime spans as primary spans for `MISMATCHED_LIFETIME_SYNTAXES` Fixes https://github.com/rust-lang/rust/issues/145772 This PR changes the primary span(s) of the `MISMATCHED_LIFETIME_SYNTAXES` to point to the *unnamed* lifetime spans in both the inputs and *outputs* of the function signature. As reported in rust-lang/rust#145772, this should make it so that IDEs highlight the spans of the actionable part of this lint, rather than just the (possibly named) input spans like they do today. This could be tweaked further perhaps, for example for `fn foo(_: T<'_>) -> T`, we don't need to highlight the elided lifetime if the actionable part is to change only the return type to `T<'_>`, but I think it's improvement on what's here today, so I think that should be follow-up since I think the logic might get a bit hairy. cc ```@shepmaster```

Add lint against integer to pointer transmutes # `integer_to_ptr_transmutes` *warn-by-default* The `integer_to_ptr_transmutes` lint detects integer to pointer transmutes where the resulting pointers are undefined behavior to dereference. ### Example ```rust fn foo(a: usize) -> *const u8 { unsafe { std::mem::transmute::<usize, *const u8>(a) } } ``` ``` warning: transmuting an integer to a pointer creates a pointer without provenance --> a.rs:1:9 | 158 | std::mem::transmute::<usize, *const u8>(a) | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: this is dangerous because dereferencing the resulting pointer is undefined behavior = note: exposed provenance semantics can be used to create a pointer based on some previously exposed provenance = help: if you truly mean to create a pointer without provenance, use `std::ptr::without_provenance_mut` = help: for more information about transmute, see <https://doc.rust-lang.org/std/mem/fn.transmute.html#transmutation-between-pointers-and-integers> = help: for more information about exposed provenance, see <https://doc.rust-lang.org/std/ptr/index.html#exposed-provenance> = note: `#[warn(integer_to_ptr_transmutes)]` on by default help: use `std::ptr::with_exposed_provenance` instead to use a previously exposed provenance | 158 - std::mem::transmute::<usize, *const u8>(a) 158 + std::ptr::with_exposed_provenance::<u8>(a) | ``` ### Explanation Any attempt to use the resulting pointers are undefined behavior as the resulting pointers won't have any provenance. Alternatively, `std::ptr::with_exposed_provenance` should be used, as they do not carry the provenance requirement or if the wanting to create pointers without provenance `std::ptr::without_provenance_mut` should be used.
