2025-05-06Rollup merge of #140687 - ehuss:update-mdbook, r=jieyouxuStuart Cook-3/+3
Update mdbook to 0.4.49 This is a routine update to pull in some fixes and updates. Changelog: https://github.com/rust-lang/mdBook/blob/master/CHANGELOG.md#mdbook-0449
2025-05-06Rollup merge of #140251 - Zalathar:coverage-dump-path, r=clubby789Stuart Cook-104/+377
coverage-dump: Resolve global file IDs to filenames The coverage-dump tool, used by coverage tests, currently includes “global file ID” numbers in its dump output. This PR adds support for parsing coverage filename information from LLVM assembly `.ll` files, and resolving those file IDs to the corresponding filename, for inclusion in dump output. This makes dump output more informative, especially for test cases involving multiple files, and will be important for testing expansion region support in the future. --- The bootstrap changes don't necessarily have to land at the same time (e.g. they could be deferred to after the stage0 redesign if requested), but I would prefer to land them now if possible.

r=jieyouxu,wesleywiser Implement RFC 3503: frontmatters Tracking issue: #136889 Supercedes #137193. This implements [RFC 3503](https://github.com/rust-lang/rfcs/blob/master/text/3503-frontmatter.md). This might break rust-analyzer. Will look into how to fix that. Suggestions welcome for how to improve diagnostics.
2025-05-06Rollup merge of #139773 - thaliaarchi:vec-into-iter-last, r=workingjubileeStuart Cook-7/+46
Implement `Iterator::last` for `vec::IntoIter` Avoid iterating everything when we have random access to the last element.

2025-05-06coverage-dump: Make filenames available to covfun record dumpingZalathar-3/+87
Actually printing the filenames is deferred to a subsequent commit that will simultaneously bless all affected tests.

2025-05-05Rollup merge of #140670 - onur-ozkan:129959, r=KobzolGuillaume Gomez-1/+1
calculate step duration in a panic-safe way obvious/self-explanatory change. Fixes #129959
2025-05-05Rollup merge of #140636 - onur-ozkan:panic-tracker-for-t-macro, r=KobzolGuillaume Gomez-5/+26
implement `PanicTracker` to track `t` panics Trying to understand panics triggered by `t` macro is very exhausting (especially on CI failures) because it doesn't provide any information about where the macro was originally invoked. This change adds that missing information when an inner call inside the `t` macro panics. Resolves #137557
2025-05-05Rollup merge of #140374 - compiler-errors:global_asm-bug, r=lcnrGuillaume Gomez-1/+1
Resolve instance for SymFn in global/naked asm `Instance::expect_resolve` ensures that we're actually going from trait item -> impl item. Fixes #140373
2025-05-05Rollup merge of #140357 - onur-ozkan:133840, r=clubby789Guillaume Gomez-9/+11
bypass linker configuration and cross target check on `x check` I was going to handle this using the untracked env approach, but I realized it somehow doesn't regress https://github.com/rust-lang/rust/issues/130108 anymore... Anyway, if it works, it works. 😄 No need to dig deeper but my guess is we moved some cache-invalidating env from these functions to others.
