Run wfcheck in one big loop instead of per module
Maybe we can merge this big loop in the future with the `par_hir_body_owners` call below and run typeck only on items that didn't fail wfcheck. For now let's just see if perf likes it, as it by itself should be beneficial to parallel rustc
Fix incorrect eq_unspanned in TokenStream
Fixesrust-lang/rust#141522
r? ``@workingjubilee``
should we remove this function?
since it's used in several places, i'd prefer to keep it.
redesign stage 0 std follow-ups part2
Fixes three bugs:
1. `x check` fails when run on rustdoc without `download-rustc` enabled. (1st commit)
2. `x check` fails when run on the compiler with `download-rustc` enabled. (2nd commit)
3. `x test library` fails with `download-rustc` enabled. (3rd commit)
Fixesrust-lang/rust#142018 (case 1)
Fixes https://github.com/rust-lang/rust/issues/141983 (case 3)

bootstrap: don't symlink source dir into stage0 sysroot
In StdLink::run we subsequently recursively copy the initial sysroot lib directory into the stage0-sysroot lib directory. If the initial sysroot is a toolchain that includes the `rust-src` component (in lib/rustlib/src/rust), if we add this symlink, that recursive copy will overwrite the repo sources with the toolchain's sources.
Fixes https://github.com/rust-lang/rust/issues/141991
index: add method for checking range on DenseBitSet
Micro-optimisation that Miri benefits from with the new isolated allocator for native-libs mode. Also possibly just a useful method to have on `DenseBitSet`
In StdLink::run we subsequently recursively copy the initial sysroot
lib directory into the stage0-sysroot lib directory. If the initial
sysroot is a toolchain that includes the `rust-src` component (in
lib/rustlib/src/rust), if we add this symlink, that recursive copy
will overwrite the repo sources with the toolchain's sources.
Use the informative error as the main const eval error message
r? `@RalfJung`
I only did the minimal changes necessary to the const eval error machinery. I'd prefer not to mix test changes with refactorings 😆
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",
```
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").
[1]: https://github.com/josh-project/josh
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. It should be especially useful on PR builds after https://github.com/rust-lang/rust/pull/141948.

Switch `x86_64-msvc-{1,2}` back to Windows Server 2025 images
New Windows Server 2025 images have been released (**20250527.1.0**). New images appear to not exhibit the lack-of-disk-space problem as tracked by rust-lang/rust#141022, and the new runner image's storage capacity appears to be configured correctly.
Windows Server 2025 image version **20250527.1.0** release notes: <https://github.com/actions/runner-images/releases/tag/win25%2F20250527.1>.

[rustdoc-json] Implement PartialOrd and Ord for rustdoc_types::Id
This allows consumers to create collections that required an ordering relationship for their keys—e.g. a `BTreeMap`.
Improve documentation for codegen options
This adds more information to many different codegen options. It should not add any new guarantees, just document existing behavior.
