2025-06-20Fix ICE in `missing_const_for_fn` (rust-lang/rust-clippy#14776)Alejandra González-2/+45
The `mir_drops_elaborated_and_const_checked` query result has been stolen already and cannot be borrowed again. Use the `optimized_mir` query result instead. changelog: [`missing_const_for_fn`]: fix ICE with some compilation options Fixes rust-lang/rust-clippy#14774 r? @Jarcho
2025-06-20`needless_borrow`: do not contradict `dangerous_implicit_autorefs` ↵Alejandra González-22/+49
(rust-lang/rust-clippy#14810) Rust 1.88 introduces the `dangerous_implicit_autorefs` lint which warns about using implicit autorefs on a place obtained from a raw pointer, as this may create aliasing issues. Prevent `clippy::needless_borrow` from triggering in this case, by disabling the lint when taking a reference on a raw pointer dereference. There might be a better way for doing this in the long run with a finer way of distinguish the problematic cases, but this will prevent Clippy from contradicting the compiler in the meantime. Fixes rust-lang/rust-clippy#14743 changelog: [`needless_borrow`]: do not contradict the compiler's `dangerous_implicit_autorefs` lint even though the refererences are not mandatory @rustbot label +beta-nominated <!-- TRIAGEBOT_START --> <!-- TRIAGEBOT_SUMMARY_START --> - [Beta nomination for 1.88](https://github.com/rust-lang/rust-clippy/pull/14810#issuecomment-2883753957) by [samueltardieu](https://github.com/samueltardieu) Generated by triagebot, see [help](https://forge.rust-lang.org/triagebot/note.html) for how to add more <!-- TRIAGEBOT_SUMMARY_DATA_START$${"entries_by_url":{"https://github.com/rust-lang/rust-clippy/pull/14810#issuecomment-2883753957":{"title":"Beta nomination for 1.88","comment_url":"https://github.com/rust-lang/rust-clippy/pull/14810#issuecomment-2883753957","author":"samueltardieu"}}}$$TRIAGEBOT_SUMMARY_DATA_END --> <!-- TRIAGEBOT_SUMMARY_END --> <!-- TRIAGEBOT_END -->

Do not deny warnings in "fast" try builds When we do the classic ``@bors` try` build without specifying `try-job` in the PR description, we want to get a compiler toolchain for perf./crater/local experimentation as fast as possible. We don't run any tests in that case, so it seems reasonable to also ignore warnings. Fixes: https://github.com/rust-lang/rust/issues/140753 r? `@jieyouxu` try-job: dist-x86_64-linux

[win][arm64] Disable various DebugInfo tests that don't work on Arm64 Windows While trying to get the aarch64-msvc build working correctly (#140136), various DebugInfo related tests were failing. I've added comments to each test to indicate why it is disabled and linked to appropriate bugs. * `tests/debuginfo/step-into-match.rs`: Stepping at the end of a function on goes to the callsite, not the instruction after it. * `tests/debuginfo/type-names.rs`: Arm64 Windows cdb doesn't support JavaScript extensions. Followed up with the Microsoft Debugger Tools team to fix this. * `tests/ui/runtime/backtrace-debuginfo.rs`: Backtraces are truncated due to #140489

2025-05-08Auto merge of #140106 - dianne:deref-pat-usefulness, r=Nadrierilbors-0/+3
allow deref patterns to participate in exhaustiveness analysis Per [this proposal](https://hackmd.io/4qDDMcvyQ-GDB089IPcHGg#Exhaustiveness), this PR allows deref patterns to participate in exhaustiveness analysis. Currently all deref patterns enforce `DerefPure` bounds on their scrutinees, so this assumes all patterns it's analyzing are well-behaved. This also doesn't support [mixed exhaustiveness](https://hackmd.io/4qDDMcvyQ-GDB089IPcHGg#Mixed-exhaustiveness), and instead emits an error if deref patterns are used together with normal constructors. I think mixed exhaustiveness would be nice to have (especially if we eventually want to support arbitrary `Deref` impls[^1]), but it'd require more work to get reasonable diagnostics[^2]. Tracking issue for deref patterns: #87121 r? `@Nadrieril` [^1]: Regardless of whether we support limited exhaustiveness checking for untrusted `Deref` or always require other arms to be exhaustive, I think it'd be useful to allow mixed matching for user-defined smart pointers. And it'd be strange if it worked there but not for `Cow`. [^2]: I think listing out witnesses of non-exhaustiveness can be confusing when they're not necessarily disjoint, and when you only need to cover some of them, so we'd probably want special formatting and/or explanatory subdiagnostics. And if it's implemented similarly to unions, we'd probably also want some way of merging witnesses; the way witnesses for unions can appear duplicated is pretty unfortunate. I'm not sure yet how the diagnostics should look, especially for deeply nested patterns.

r=jieyouxu run-make-support: set rustc dylib path for cargo wrapper Some run-make tests invoke Cargo via run_make_support::cargo(), but fail to execute correctly when rustc is built without rpath. In these setups, runtime loading of rustc’s shared libraries fails unless the appropriate dynamic library path is set manually. This commit updates the cargo() wrapper to call set_host_compiler_dylib_path(), aligning its behavior with the existing rustc() wrapper: https://github.com/rust-lang/rust/blob/f76c7367c6363d33ddb5a93b5de0d158b2d827f6/src/tools/run-make-support/src/external_deps/rustc.rs#L39-L43 This ensures that Cargo invocations during tests inherit the necessary dylib paths, avoiding errors related to missing shared libraries in rpath-less builds.

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.
