`find()` has a missing example. In the docs there was a mention of an example with double reference but it didn't exist. `rfind()` is also very similar to `find()`, however it had the double reference example and no owned value example like `find()` did. This commit adds the missing examples and making them look consistent.
Change the `SmallVec` size from 4 to 1, because that's sufficient in the vast majority of cases. (This doesn't affect performance in practice, so it's more of a code clarity change than a performance change.)
…t args
Detect the `{ident?}` pattern where `?` is immediately followed by `}` and emit
a clearer diagnostic explaining that `:` is required for Debug formatting.
This avoids falling back to a generic “invalid format string” error and adds
a targeted UI test for the case.

…imulacrum Use realstd current thread static variables in tests Fixes rust-lang#150053. This PR basically exports `thread::current::CURRENT` & `thread::current::ID*` static variables and be referred to them when testing. I also added a minor refactoring which collects symbols referred as `readlstd::...` in `test_internals` module. If approved, i would kindly ask this PR to be beta nominated. Thank you.
…tmcm docs(core): update `find()` and `rfind()` examples [find()](https://doc.rust-lang.org/std/iter/trait.Iterator.html) has a missing example. In the docs there is mention of an example with double reference but it doesn't exist. <img width="1476" height="1229" alt="image" src="https://github.com/user-attachments/assets/b99062ed-3a47-4b87-8e0c-58afd7de1332" /> [rfind()](https://doc.rust-lang.org/core/iter/trait.DoubleEndedIterator.html#method.rfind) is also very similar to `find()`, however it has the double reference example and no owned value example like `find()` does. <img width="1473" height="1163" alt="image" src="https://github.com/user-attachments/assets/7977ae5c-9888-4513-8dfc-a7c03c7ef072" /> This commit adds the missing examples and making them look consistent.
adding Ordering enum to minicore.rs, importing minicore in "tests/assembly-llvm/rust-abi-arg-attr.rs" test file this adds the `Ordering` enum to `minicore.rs`. consequently, this updates `tests/assembly-llvm/rust-abi-arg-attr.rs` to import `minicore` directly. previously, this test file contained traits like `Copy` `Clone` `PointeeSized`, which were giving a duplicate lang item error, so replace those by importing `minicore` completely.
Finish transition from `semitransparent` to `semiopaque` for `rustc_macro_transparency` Since it's a bit annoying to have different names for the same thing. My understanding is that this is just internal stuff that is not part of any public API even tough rust-analyzer knows about it. Continuation of - rust-lang#139084. Discovered while investigating - rust-lang#150514
Clarify `MoveData::init_loc_map`. Change the `SmallVec` size from 4 to 1, because that's sufficient in the vast majority of cases. (This doesn't affect performance in practice, so it's more of a code clarity change than a performance change.) r? @cjgillot
mgca: Type-check fields of struct expr const args Fixes rust-lang#150623. Fixes rust-lang#150712. Fixes rust-lang#150714. Fixes rust-lang#150734. r? @BoxyUwU
Use functions more in rustdoc GUI tests Now that conditions are supported in `browser-ui-test`, we can start simplify some parts of the tests. This is a first cleanup, but I guess a lot more could be simplified. For follow-ups I guess. :) I made some improvements in backtrace display in `browser-ui-test`, hence the version update once more. r? @lolbinarycat
rustc_parse_format: improve error for missing `:` before `?` in format args
Detect the `{ident?}` pattern where `?` is immediately followed by `}` and emit a clearer diagnostic explaining that `:` is required for Debug formatting. This avoids falling back to a generic “invalid format string” error and adds a targeted UI test for the case.
Fix trait method anchor disappearing before user can click on it A good example of this bug is going to https://doc.rust-lang.org/nightly/nightly-rustc/rustc_hir_analysis/collect/struct.ItemCtxt.html#impl-HirTyLowerer%3C'tcx%3E-for-ItemCtxt%3C'tcx%3E, and then try to click on the `§` anchor of the `tcx` method. The solution to this bug is to simply "glue" the anchor to the method, so when the mouse cursor moves to it, there is no gap between the two, preventing the anchor to disappear (hopefully this explanation doesn't make sense only to me ^^'). First commit fixes the bug by expanding the anchor size. Second commit is a small clean-up of the GUI test. Third commit actually adds the GUI regression test. cc @BoxyUwU r? @camelid
tests/ui/borrowck/issue-92157.rs: Remove (bug not fixed) The bug the test tests for is masked by the wrong `#[lang = "start"]` signature. If the signature is corrected, the test builds. But that is not because the bug is fixed, but because the test has been changed too much from the original reproducer. The original reproducer still ICE:s. See rust-lang#92157 (comment). But that's fine since in the latest compiler says: > note: using internal features is not supported and expected to cause internal compiler errors when used incorrectly So let's remove the test and close the issue as "won't fix". See rust-lang#92157 (comment). r? @JohnTitor since you added the test in rust-lang#106878
