const-block-as-pattern: do not refer to no-longer-existing nightly feature Surely everyone who used this nightly feature has fixed their code by now. So let's not confused people on stable that try to use a const block as a pattern by referring to some dead nightly feature.

2025-07-08Rollup merge of #143567 - xizheyin:143336, r=compiler-errorsMatthias Krüger-7/+40
Point to correct argument in Func Call when Self type fails trait bound Fixes rust-lang/rust#143336 When a trait bound fails due to the `Self` type parameter, `adjust_fulfillment_errors` now correctly points to the corresponding function argument instead of incorrectly pointing to other arguments. This is because `Call` may also need to handle the `self` parameter, and not just `MethodCall` needs to be handled, as rust-lang/rust#143336. r? compiler

Dont resolve instance of root in `mir_callgraph_cyclic` `Instance::try_resolve` on a default trait body method will always fail, since it's still possible to further substitute. This leads to a cycle, since in `tests/mir-opt/inline_default_trait_body.rs`, both `Trait::a` and `Trait::b` need to consider the other to be cyclical, but since we couldn't resolve a body, we'd just consider *nothing* to be cyclical. The root instance we care about when computing `mir_callgraph_cyclic` is trivial to compute (it's just `InstanceKind::Item`), so just replace it with a call to `Instance::new_raw`. r? `@cjgillot` `@oli-obk` Fixes rust-lang/rust#143534

Move `stable_mir` back to its own crate We've finished the refactoring, so it's time to move `stable_mir` back to its own crate. This PR leaves an empty `rustc_internal` module with a `#[deprecated]` attribute in `rustc_smir` to let users know we just moved it to `stable_mir`.
2025-07-07Rollup merge of #143482 - ia0:fix, r=fee1-dead许杰友 Jieyou Xu (Joe)-4/+25
Fix short linker error output This PR does 2 things: - It removes the braces when there's a single element. This is required since brace expansion (at least in bash and zsh) only triggers if there's at least 2 elements. - It removes the extra `.rlib` suffixes of the elements. See https://github.com/rust-lang/rust/pull/135707#discussion_r2185212393 for context. Running `cargo +stage1 build` on the following program: ```rust unsafe extern "C" { fn foo() -> libc::c_int; } fn main() { let x = unsafe { foo() } as u32; // println!("{}", data_encoding::BASE64.encode(&x.to_le_bytes())); } ``` Gives the following diff before and after the PR: ```diff -/tmp/foo/target/debug/deps/{liblibc-faf416f178830595.rlib}.rlib +/tmp/foo/target/debug/deps/liblibc-faf416f178830595.rlib ``` Running on the same program with the additional dependency, we get the following diff: ```diff -/tmp/foo/target/debug/deps/{liblibc-faf416f178830595.rlib,libdata_encoding-84bb5aadfa9e8839.rlib}.rlib +/tmp/foo/target/debug/deps/{liblibc-faf416f178830595,libdata_encoding-84bb5aadfa9e8839}.rlib ```

2025-07-06Auto merge of #143509 - cjgillot:copy-prop-noborrow, r=tmiaskobors-281/+830
Do not unify borrowed locals in CopyProp. Instead of trying yet another scheme to unify borrowed locals in CopyProp, let's just stop trying. We had already enough miscompilations because of this. I'm convinced it's possible to have both unification of some borrowed locals and soundness, but I don't have a simple and convincing formulation yet.

Stop using `Key` trait unnecessarily Few places where the `Key` trait was being used but not really for a useful reason. This fixes those usages. Namely, `<Ty as Key>::default_span()` is `DUMMY_SP` anyways.
