2025-09-27Auto merge of #138907 - GuillaumeGomez:rfc-3631, ↵bors-371/+1046
r=fmease,camelid,Manishearth,lolbinarycat Implement RFC 3631: add rustdoc doc_cfg features Implementation of https://github.com/rust-lang/rfcs/pull/3631. This implementation actually resulted in a lot of simplifications: * All `cfg` computation is now done in one place: `propagate_doc_cfg.rs`. Because (trait) `impl`s are not retrieved at the same time as the other items, we cannot perform this computation in the clean process, it needs to be after. * Because there is `cfg` inheritance, we can keep track of them in one place (in `propagate_doc_cfg.rs`), meaning we don't need to copy an item's attributes to its children anymore. Only exception: impl items. For them we clone only `cfg` attributes. * `propagate_doc_cfg.rs` is also now much simpler, much less need to keep track of parents, since everything we need is handled by the new `CfgInfo` type. * I also suspect that `Cfg::simplify_with` could either be removed or at least used directly into `propagate_doc_cfg.rs` when we compute `cfg`s. Considering how big the PR already is, I'll do it in a follow-up. I didn't remove the `doc_cfg*` features in this PR because some dependencies used in `rustc` (like `stdarch`) are using it, so we need to have a nightly released with this PR before I can switch to the new feature. r? ghost
2025-09-27Auto merge of #146829 - cjgillot:jump-threading-loop-dominator, r=dianqkbors-17/+25
JumpThreading: Avoid computing dominators to identify loop headers. JumpThreading tries to avoid threading through loop headers to avoid creating irreducible CFGs. However, computing dominators is expensive, and accounts up to 20 % of the runtime of the JumpThreading pass for some cases like serde. This PR proposes to approximate according to the post-order traversal order. We define a "maybe" loop header as a block which is visited after its predecessor in post-order.

2025-09-26Rollup merge of #146778 - nikic:allocator-shim-attributes, r=jackh726Matthias Krüger-114/+126
Use standard attribute logic for allocator shim Use llfn_attrs_from_instance() to generate the attributes for the allocator shim. This ensures that we generate all the usual attributes (and don't get to find out one-by-one that a certain attribute is important for a certain target). Additionally this will enable emitting the allocator-specific attributes (not included here). This change is quite awkward because the allocator shim uses SimpleCx, while llfn_attrs_from_instance uses CodegenCx. I've switched it to use SimpleCx plus tcx/sess arguments where necessary. If there's a simpler way to do this, I'd love to know about it...
2025-09-26Rollup merge of #146758 - mati865:amd64_mingw_no_rs_objects, r=petrochenkovMatthias Krüger-7/+23
Stop linking rs{begin,end} objects on x86_64-*-windows-gnu Until now, x86_64-pc-windows-gnu linked `rsbegin.o` and `rsend.o` just like i686-pc-windows-gnu, even though they were no-ops for it. This was likely done for the simplicity back when it was introduced. Today the things are different and these startup/end objects harm other features, like `build-std`. Given the demotion of i686-pc-windows-gnu from tier 1, there is no point in hurting x86_64-pc-windows-gnu, which remains a tier 1. The files are still shipped in case downstream crates expect them, as in case of the unmaintained `xargo`. Fixes https://github.com/rust-lang/rust/issues/146739

2025-09-26Rollup merge of #146523 - thejpster:demote-armebv7r-targets, r=jackh726Matthias Krüger-5/+5
Demote both armebv7r-none-* targets. OK, slightly more controversial than https://github.com/rust-lang/rust/pull/146520 and https://github.com/rust-lang/rust/pull/146522 - I'd like to drop the bare-metal **big-endian** Armv7-R targets down to Tier 3. The reason is simple - we cannot test them in https://github.com/rust-embedded/cortex-ar/. This because QEMU support for Big Endian Armv7-R is broken. I tried quite hard, but all the strings I printed with semihosting came out byte swapped (or "etybawa depp") because of how QEMU kludges the access to memory in big-endian mode. The target also has only a single maintainer. Although, if ````@chrisnc```` wants to put up a case for keeping it at Tier 2 though, I'm happy to hear it! This PR wil be rebased once https://github.com/rust-lang/rust/pull/146419 completes the queue.
2025-09-26Rollup merge of #145113 - petrochenkov:lessfinalize, r=lcnrMatthias Krüger-15/+39
resolve: Do not finalize shadowed bindings I.e. do not mark them as used, or non-speculatively loaded, or similar. Previously they were sometimes finalized during early resolution, causing issues like https://github.com/rust-lang/rust/pull/144793#issuecomment-3168108005.
2025-09-26Auto merge of #146885 - lcnr:method-selection-opaques, r=BoxyUwUbors-291/+647
support opaque types in method selection See my notes in https://hackmd.io/4ILASx3mQ3u_gW9r1JyqCw. This PR builds on https://github.com/rust-lang/rust/pull/145993 and allows not-yet defined opaque types as self types in the `method_autoderef_chain`. E.g. for `Box<impl Deref<impl Foo>>` this results in the autoderef chain `Box<impl Deref> -> ?deref_hidden_ty -> ?foo_hidden_ty`. Method selection stays ambiguous if the final autoderef step is still an infer var unless that var is an opaque. TODO: treating opaques as rigid jank. r? `@BoxyUwU`

We'll still error due to the `opt_bad_ty` of `method_autoderef_steps`. This slightly worsens the span of `infer_var.method()` which is now the same as for `Box::new(infer_var).method()`. Unlike `structurally_resolve_type`, `probe_op` does not check whether the infcx is already tainted, so this results in 2 previously not emitted errors.
