For https://github.com/rust-lang/rust-clippy/issues/6680 I wanted to move the lint into `functions` because it has a `check_fn` part, but it also has a `check_stmt`, which I wouldn't know what to do with. changelog: none

2025-09-08Auto merge of #145910 - saethlin:ignore-intrinsic-calls, r=cjgillotbors-1/+25
Ignore intrinsic calls in cross-crate-inlining cost model I noticed in a side project that a function which just compares to `[u64; 2]` for equality is not cross-crate-inlinable. That was surprising to me because I didn't think that code contained a function call, but of course our array comparisons are lowered to an intrinsic. Intrinsic calls don't make a function no longer a leaf, so it makes sense to add this as an exception to the "only leaves" cross-crate-inline heuristic. This is the useful compare link: https://perf.rust-lang.org/compare.html?start=7cb1a81145a739c4fd858abe3c624ce8e6e5f9cd&end=c3f0a64dbf9fba4722dacf8e39d2fe00069c995e&stat=instructions%3Au because it disables CGU merging in both commits, so effects that cause changes in the sysroot to perturb partitioning downstream are excluded. Perturbations to what is and isn't cross-crate-inlinable in the sysroot has chaotic effects on what items are in which CGUs after merging. It looks like before this PR by sheer luck some of the CGUs dirtied by the patch in eza incr-unchanged happened to be merged together, and with this PR they are not. The perf runs on this PR point to a nice runtime performance improvement.
2025-09-07Auto merge of #145541 - cjgillot:dest-prop-live-range, r=Amanieubors-615/+401
Reimplement DestinationPropagation according to live ranges. This PR reimplements DestinationPropagation as a problem of merging live-ranges of locals. We merge locals that have disjoint live-ranges. This allows merging several locals in the same round by updating live range information. Live ranges are mainly computed using the `MaybeLiveLocals` analysis. The subtlety is that we split each statement and terminator in 2 positions. The first position is the regular statement. The second position is a shadow, which is always more live. It encodes partial writes and dead writes as a local being live for half a statement. This half statement ensures that writes conflict with another local's writes and regular liveness. r? `@Amanieu`

That way it doesn't need to be exported.
2025-09-08Move `rustc_middle::MaxUniverse` to `rustc_infer`.Nicholas Nethercote-42/+41
Because `rust_infer` is the only crate that uses it.

Exhaustive match isn't necessary for these trivial cases, and some similar nearby methods are non-exhaustive.

2025-09-07Rollup merge of #146269 - weihanglo:solaris-flock, r=Mark-SimulacrumMatthias Krüger-0/+70
feat(std): emulate flock for solaris via fcntl Upstream Solaris flock emulation to libstd from cargo. This is borrowed from https://github.com/rust-lang/cargo/blob/3b379fcc541b39321a7758552d37e5e0cc4277b9/src/cargo/util/flock.rs#L502-L536 which was implemented by an Oracle employee. The code has been in cargo since 2022-12. Python's `fcntl.flock` emulates like this as well: https://github.com/python/cpython/blob/c919d02edecfe9d75fe374756fb8aa1db8d95f55/Modules/fcntlmodule.c#L337-L400 We did the same thing in https://github.com/rust-lang/rust/blob/0d0f4eac8b98133e5da6d3604d86a8f3b5a67844/compiler/rustc_data_structures/src/flock/unix.rs#L13-L39 However, should we just always falls back to fcntl for all Unix, instead of "unsupported"? try-job: `*-solaris`

fix: offline rustdoc html missing favicon As discussed in the rust-lang/rust#146149 the doc was missing the favicon icon when build locally and viewed on a browser. I changed the relative path and also now we explicitly copy both SVG and PNG. <img width="1132" height="425" alt="Screenshot 2025-09-03 at 11 57 46 PM" src="https://github.com/user-attachments/assets/062cbb08-04ec-4d88-a43a-710fb6190f82" />

2025-09-07`let_unit_with_type_underscore`: make early-pass (#15458)Jason Newcomb-11/+137
This kind of supersedes https://github.com/rust-lang/rust-clippy/pull/15386 -- by making the lint early-pass, we get access to `TyKind::Paren`s that surround the type ascription. And with that, we can return to the simpler calculation of `span_to_remove`. The biggest hurdle was `is_from_proc_macro` -- calling that function required me to `impl WithSearchPat for rustc_ast::Ty`, i.e. `ast_ty_search_pat`, which I based on `ty_search_pat`. Since that's a larger change, I could extract it into a PR of its own. changelog: none
