Make -Ztrack-diagnostics emit like a note [#t-compiler/diagnostics > Rendering -Ztrack-diagnostics like a note](https://rust-lang.zulipchat.com/#narrow/channel/147480-t-compiler.2Fdiagnostics/topic/Rendering.20-Ztrack-diagnostics.20like.20a.20note/with/526608647) As discussed on the Zulip thread above, I want to make `-Ztrack-diagnostics` emit like a `note`. This is because I find its current output jarring, and the fact that it gets rendered completely left-aligned, [even in the middle of a snippet](https://github.com/rust-lang/rust/blob/86e05cd300fac9e83e812c4d46582b48db780d8f/tests/ui/track-diagnostics/track6.stderr), seems like something that should be changed. Turning it into a `note` seems like the best choice, as it would align it with the rest of the output, and `note` is already used for somewhat similar things, like seeing why a lint was fired. --- Note: turning `-Ztrack-diagnostics` into a `note` will also make `annotate-snippets` API a bit cleaner

2025-07-04treat box patterns as deref patterns in THIR and usefulness analysisdianne-15/+27
This removes special-casing of boxes from `rustc_pattern_analysis`, as a first step in replacing `box_patterns` with `deref_patterns`. Incidentally, it fixes a bug caused by box patterns being represented as structs rather than pointers, where `exhaustive_patterns` could generate spurious `unreachable_patterns` lints on arms required for exhaustiveness; following the lint's advice would result in an error.

The modified test files are reported in https://github.com/rust-lang/rust/issues/143319 as failing for `--target=riscv64gc-unknown-linux-gnu`.

setup typos check in CI This allows to check typos in CI, currently for compiler only (to reduce commit size with fixes). With current setup, exclude list is quite short, so it worth trying? Also includes commits with actual typo fixes. MCP: https://github.com/rust-lang/compiler-team/issues/817 typos check currently turned for: * ./compiler * ./library * ./src/bootstrap * ./src/librustdoc After merging, PRs which enables checks for other crates (tools) can be implemented too. Found typos will **not break** other jobs immediately: (tests, building compiler for perf run). Job will be marked as red on completion in ~ 20 secs, so you will not forget to fix it whenever you want, before merging pr. Check typos: `python x.py test tidy --extra-checks=spellcheck` Apply typo fixes: `python x.py test tidy --extra-checks=spellcheck:fix` (in case if there only 1 suggestion of each typo) Current fail in this pr is expected and shows how typo errors emitted. Commit with error will be removed after r+.

2025-07-02Rollup merge of #143070 - joshtriplett:macro-rules-parse, r=petrochenkovMatthias Krüger-10/+12
Rewrite `macro_rules!` parser to not use the MBE engine itself The `macro_rules!` parser was written to match the series of rules using the macros-by-example (MBE) engine and a hand-written equivalent of the left-hand side of a MBE macro. This was complex to read, difficult to extend, and produced confusing error messages. Because it was using the MBE engine, any parse failure would be reported as if some macro was being applied to the `macro_rules!` invocation itself; for instance, errors would talk about "macro invocation", "macro arguments", and "macro call", when they were actually about the macro *definition*. And in practice, the `macro_rules!` parser only used the MBE engine to extract the left-hand side and right-hand side of each rule as a token tree, and then parsed the rest using a separate parser. Rewrite it to parse the series of rules using a simple loop, instead. This makes it more extensible in the future, and improves error messages. For instance, omitting a semicolon between rules will result in "expected `;`" and "unexpected token", rather than the confusing "no rules expected this token in macro call". This work was greatly aided by pair programming with Vincenzo Palazzo (`@vincenzopalazzo)` and Eric Holk (`@eholk).` For review, I recommend reading the two commits separately.
2025-07-02Rollup merge of #142964 - GrigorenkoPV:attributes/argless, r=oli-obkMatthias Krüger-8/+8
Attribute rework: a parser for single attributes without arguments Part of rust-lang/rust#131229 r? `@jdonszelmann` I think code (with comments) speaks for itself. The only subtlety: now `#[cold]`, `#[no_mangle]`, & `#[track_caller]` do not get thrown away when malformed (i.e. have arguments). This doesn't matter too much (I think), because an error gets emitted either way, so the compilation will not finish.

Expose elf abi on ppc64 targets Fixes https://github.com/rust-lang/rust/issues/60617 (after MCP https://github.com/rust-lang/compiler-team/issues/885 is accepted) by exposing the abi information on ppc64 targets. Conditional compilation can now use `cfg(target_abi = "elfv1")` or `cfg(target_abi = "elfv2")` to determine the abi in use. Technical details are included in the other PR https://github.com/rust-lang/rust/pull/142598

Remove let_chains unstable feature Per https://github.com/rust-lang/rust/issues/53667#issuecomment-3016742982 (but then I also noticed rust-lang/rust#140722) This replaces the feature gate with a parser error that says let chains require 2024. A lot of tests were using the unstable feature. I either added edition:2024 to the test or split out the parts that require 2024.
