2025-07-30Introduce proper `build.compiletest-allow-stage0` config optionJieyou Xu-6/+24
In favor of the adhoc `COMPILETEST_FORCE_STAGE0` env var.
2025-07-30Fix tests for big-endianEduard Stefes-8/+10
The tests fail on s390x and presumably other big-endian systems, due to print of raw values and padding bytes. To fix the tests remove the raw output values in the error note with `normalize-stderr`.

2025-07-30Rollup merge of #144666 - compiler-errors:correct-late, r=lqdStuart Cook-6/+97
Make sure to account for the right item universal regions in borrowck Fixes https://github.com/rust-lang/rust/issues/144608. The ICE comes from a mismatch between the liberated late bound regions (i.e. "`ReLateParam`"s) that come from promoting closure outlives, and the regions we have in our region vid mapping from `UniversalRegions`. When building `UniversalRegions`, we end up using the liberated regions from the binder of the closure's signature: https://github.com/rust-lang/rust/blob/c8bb4e8a126cf38cff70cea488a3a423a5321954/compiler/rustc_borrowck/src/universal_regions.rs#L521 Notably, this signature may be anonymized if the closure signature being deduced comes from an external constraints: https://github.com/rust-lang/rust/blob/c8bb4e8a126cf38cff70cea488a3a423a5321954/compiler/rustc_hir_typeck/src/closure.rs#L759-L762 This is true in the test file I committed, where the signature is influenced by the `impl FnMut(&mut ())` RPIT. However, when promoting a type outlives constraint we end up creating a late bound lifetime mapping that disagrees with those liberated late bound regions we constructed in `UniversalRegions`: https://github.com/rust-lang/rust/blob/c8bb4e8a126cf38cff70cea488a3a423a5321954/compiler/rustc_borrowck/src/universal_regions.rs#L299 Specifically, in `for_each_late_bound_region_in_item` (which is called by `for_each_late_bound_region_in_recursive_scope`), we were using `tcx.late_bound_vars` which uses the late bound regions *from the HIR*. This query both undercounts the late bound regions (e.g. those that end up being deduced from bounds), and also doesn't account for the fact that we anonymize them in the signature as mentioned above. https://github.com/rust-lang/rust/blob/c8bb4e8a126cf38cff70cea488a3a423a5321954/compiler/rustc_borrowck/src/universal_regions.rs#L977 This PR fixes that function to use the *correct signature*, which properly considers the bound vars that come from deducing the signature of the closure, and which comes from the closure's args from the `type_of` query.

compiletest: Move directive names back into a separate file This list no longer needs to be included in multiple crates, but having the list in its own file makes it easier to find and update when necessary. As discussed at https://github.com/rust-lang/rust/pull/143850#issuecomment-3130307023.

Add method `find_ancestor_not_from_macro` and `find_ancestor_not_from_extern_macro` to supersede `find_oldest_ancestor_in_same_ctxt` As I was using it, I realized that the function is supposed to walk up to expand the chain? This seems to be the opposite of what I understood. r? `@jieyouxu`
2025-07-30Rollup merge of #144042 - dpaoliello:verifyllvmcomp, r=jieyouxuStuart Cook-97/+277
Verify llvm-needs-components are not empty and match the --target value I recently discovered a test with an empty `llvm-needs-components` entry (fixed in rust-lang/rust#143979) which meant that it didn't work correctly when building Rust with a limited set of LLVM targets. This change makes a pair of improvements to prevent this issue from creeping in again: * When parsing directives with values, `compiletest` will now raise an error if there is an empty value. * Improved the `target_specific_tests` tidy checker to map targets to LLVM components, to verify that any existing `llvm-needs-components` contains the target being used. I also fixed all the issues flagged by the improved tidy checker.

Free disk space on Windows 2025 runners I've managed to reduce the time deletion takes by: - Using powershell, which is generally faster for filesystem operations than msys2 - Performing deletions concurrently then waiting for them all to complete It still takes 2-10 mins but that's not too bad.

r=jieyouxu,Urgau Enable T-compiler backport nomination This patches the triagebot.toml so that it will trigger a backport label on pull requests fixing regressions. Applying a backport label will trigger creating a Zulip thread. For now the configuration only for `T-compiler` labeled regressions. Comments in the code explain how it works. Documentation [on the forge](https://forge.rust-lang.org/triagebot/backport.html). ``` [backport.foo] # The pull request MUST have one of these labels required_pr_labels = ["T-compiler"] # The regression MUST have this label required_issue_label = "regression-from-stable-to-beta" # if the above conditions matches, the PR will receive these labels add_labels = ["beta-nominated"] ``` Anything to think about before merging this? thanks for a review

2025-07-30Optimize some usages of double unary operators in suggestionsSamuel Tardieu-40/+101
When an expression is made of a `!` or `-` unary operator which does not change the type of the expression, use a new variant in `Sugg` to denote it. This allows replacing an extra application of the same operator by the removal of the original operator instead. Also, when adding a unary operator to a suggestion, do not enclose the operator argument in parentheses if it starts with a unary operator itself unless it is a binary operation (including `as`), because in this case parentheses are required to not bind the lhs only. Some suggestions will now be shown as `x` instead of `!!x`. Right now, no suggestion seems to produce `--x`.
