2025-06-03Rollup merge of #141945 - nnethercote:rm-Path-is_ident, r=compiler-errorsMatthias Krüger-14/+10
Remove `Path::is_ident`. It checks that a path has a single segment that matches the given symbol, and that there are zero generic arguments. It has a single use. We also have `impl PartialEq<Symbol> for Path` which does exactly the same thing *except* it doesn't check for zero generic arguments, which seems like an oversight. It has numerous uses. This commit removes `Path::is_ident`, adds a test for zero generic arguments to `PartialEq<Symbol> for Path`, and changes the single use of `is_ident` to instead use `==`. r? `@wesleywiser`
2025-06-03Rollup merge of #141943 - nnethercote:rm-pre-expansion-ast-stats, ↵Matthias Krüger-122/+61
r=compiler-errors Remove pre-expansion AST stats. They're very little value, because they only measure the top-level `main.rs` or `lib.rs` file. (Other `.rs` files don't get read and parsed until expansion occurs.) I saw an example recently where the pre-expansion AST was 3KB in size and the post-expansion AST was 66MB. I kept the "POST EXPANSION" in the output header, I think that's useful information to avoid possible confusion about when the measurement happens. r? `@davidtwco`

Remove bootstrap cfgs from library/ These `cfg(bootstrap)` are always false now that rust-lang/rust#119899 has landed, and likewise `cfg(not(bootstrap))` is always true. Therefore, we don't need to wait for the usual stage0 bump to clean these up.

2025-06-03Rollup merge of #141569 - workingjubilee:canonicalize-abi, r=bjorn3Matthias Krüger-788/+879
Replace ad-hoc ABI "adjustments" with an `AbiMap` to `CanonAbi` Our `conv_from_spec_abi`, `adjust_abi`, and `is_abi_supported` combine to give us a very confusing way of reasoning about what _actual_ calling convention we want to lower our code to and whether we want to compile the resulting code at all. Instead of leaving this code as a miniature adventure game in which someone tries to combine stateful mutations into a Rube Goldberg machine that will let them escape the maze and arrive at the promised land of codegen, we let `AbiMap` devour this complexity. Once you have an `AbiMap`, you can answer which `ExternAbi`s will lower to what `CanonAbi`s (and whether they will lower at all). Removed: - `conv_from_spec_abi` replaced by `AbiMap::canonize_abi` - `adjust_abi` replaced by same - `Conv::PreserveAll` as unused - `Conv::Cold` as unused - `enum Conv` replaced by `enum CanonAbi` target-spec.json changes: - If you have a target-spec.json then now your "entry-abi" key will be specified in terms of one of the `"{abi}"` strings Rust recognizes, e.g. ```json "entry-abi": "C", "entry-abi": "win64", "entry-abi": "aapcs", ```
2025-06-03Rollup merge of #141455 - joboet:tls_exhaustion_abort, r=tgross35Matthias Krüger-11/+10
std: abort the process on failure to allocate a TLS key The panic machinery uses TLS, so panicking if no TLS keys are left can lead to infinite recursion (see https://github.com/rust-lang/rust/issues/140798#issuecomment-2872307377). Rather than having separate logic for the panic count and the thread name, just always abort the process if a TLS key allocation fails. This also has the benefit of aligning the key-based TLS implementation with the documentation, which does not mention that a panic could also occur because of resource exhaustion.

2025-06-03Auto merge of #141229 - tgross35:builtins-josh-subtree, r=Kobzolbors-3/+53018
Merge `compiler-builtins` as a Josh subtree Use the Josh [1] utility to add `compiler-builtins` as a subtree, which will allow us to stop using crates.io for updates. This is intended to help resolve some problems when unstable features change and require code changes in `compiler-builtins`, which sometimes gets trapped in a bootstrap cycle. This was done using `josh-filter` built from the r24.10.04 tag: git fetch https://github.com/rust-lang/compiler-builtins.git 233434412fe7eced8f1ddbfeddabef1d55e493bd josh-filter ":prefix=library/compiler-builtins" FETCH_HEAD git merge --allow-unrelated FILTERED_HEAD The HEAD in the `compiler-builtins` repository is 233434412f ("fix an if statement that can be collapsed").

2025-06-03Add `iter` macroOli Scherer-61/+826
This adds an `iter!` macro that can be used to create movable generators. This also adds a yield_expr feature so the `yield` keyword can be used within iter! macro bodies. This was needed because several unstable features each need `yield` expressions, so this allows us to stabilize them separately from any individual feature.

Use ccache for stage0 tool builds Now after the stage0 redesign, we can actually start ccaching the build of the compiler itself. We can also cache the bootstrap tools, since these are also built with the stage0 compiler. Stage0 compiler builds are now being cached: https://github.com/rust-lang/rust/actions/runs/15397246267#summary-43321151192 (`..bootstrap::core::build_steps::compile::Rustc 483.10s 40.41s -91.6%`). It's not a gigantic win everywhere, but it should help. It seems to make the Linux jobs ~10 minute faster.

Windows Server 2025 image version **20250527.1.0** release notes: <https://github.com/actions/runner-images/releases/tag/win25%2F20250527.1>. Resolves rust-lang/rust#141022.

fix(#141141): When expanding `PartialEq`, check equality of scalar types first. Fixes rust-lang/rust#141141. Now, `cs_eq` function of `partial_eq.rs` compares [scalar types](https://doc.rust-lang.org/rust-by-example/primitives.html#scalar-types) first. - Add `is_scalar` field to `FieldInfo`. - Add `is_scalar` method to `TyKind`. - Pass `FieldInfo` via `CsFold::Combine` and refactor code relying on it. - Implement `TryFrom<&str>` and `TryFrom<Symbol>` for FloatTy. - Implement `TryFrom<&str>` and `TryFrom<Symbol>` for IntTy. - Implement `TryFrom<&str>` and `TryFrom<Symbol>` for UintTy.

Decouple "reporting in deps" from `FutureIncompatibilityReason` The reason should just be it -- the reason. It never felt right to me that it was also responsible for whatever we include the warning in cargo's reports. It gets especially unruly if you want to add non-`FutureReleaseError*` warnings which are included in the reports. I just added a field to `FutureIncompatibleInfo` to control whatever the diagnostic is included in the cargo's reports.
