r=jieyouxu minicore: use core's `diagnostic::on_unimplemented` messages Without these attributes, the error message is different. Keeping the diagnostics up-to-date seems related to https://github.com/rust-lang/rust/issues/137531. The modified test files are reported in https://github.com/rust-lang/rust/issues/143319 as failing for `--target=riscv64gc-unknown-linux-gnu`. Using `minicore` for them makes it easier to troubleshoot this sort of issue. r? ``@jieyouxu``

2025-06-29update AST-to-HIR lowering examples for conditionals and loopsdianne-4/+2
- `for` loops now use two `match`es for all of their bindings. I'm not sure this is the most helpful way of conveying that, but it's about as informative as before while staying brief. - `while let` and `if let` don't use `match`; they use `let` expressions in their conditions. Since `if let` no longer has significantly different desugaring and having a whole bullet point for `while` would feel redundant with `for`, I've removed those examples.

Add PrintTAFn flag for targeted type analysis printing ## Summary This PR adds a new `PrintTAFn` flag to the `-Z autodiff` option that allows printing type analysis information for a specific function, rather than all functions. ## Changes ### New Flag - Added `PrintTAFn=<function_name>` option to `-Z autodiff` - Usage: `-Z autodiff=Enable,PrintTAFn=my_function_name` ### Implementation Details - **Rust side**: Added `PrintTAFn(String)` variant to `AutoDiff` enum - **Parser**: Updated `parse_autodiff` to handle `PrintTAFn=<function_name>` syntax with proper error handling - **FFI**: Added `set_print_type_fun` function to interface with Enzyme's `FunctionToAnalyze` command line option - **Documentation**: Updated help text and documentation for the new flag ### Files Modified - `compiler/rustc_session/src/config.rs`: Added `PrintTAFn(String)` variant - `compiler/rustc_session/src/options.rs`: Updated parser and help text (now shows `PrintTAFn` in the list) - `compiler/rustc_codegen_llvm/src/llvm/enzyme_ffi.rs`: Added FFI function and static variable - `compiler/rustc_codegen_llvm/src/back/lto.rs`: Added handling for new flag - `src/doc/rustc-dev-guide/src/autodiff/flags.md`: Updated documentation - `src/doc/unstable-book/src/compiler-flags/autodiff.md`: Updated documentation ## Testing The flag can be tested with: ```bash rustc +enzyme -Z autodiff=Enable,PrintTAFn=square test.rs ``` This will print type analysis information only for the function named "square" instead of all functions. ## Error Handling The parser includes proper error handling: - Missing argument: `PrintTAFn` without `=<function_name>` will show an error - Unknown options: Invalid autodiff options will be reported r? ```@ZuseZ4```

Document subdirectories of UI tests with README files Part of rust-lang/rust#133895 and the [2025 Google Summer of Code](https://blog.rust-lang.org/2025/05/08/gsoc-2025-selected-projects/) associated project. When adding a new UI test, one is faced with hundreds of subdirectories in `tests/ui` reflecting various categories. Knowing where to put the new test is not trivial, as many of the categories have slightly misleading names. For example, `moves` does not only refer to the `move` keyword but to functions taking ownership in general, whereas `allocator` does not refer to allocation in general but rather to the very specific `allocator_api` and `global_allocator` features. Many contributors will therefore place their test at the top level of ̀`tests/ui` where it will be mixed with hundreds of unrelated tests. This PR is a tentative move towards more clearly defined tag/categories, with a SUMMARY.md file documenting the true purpose of each subdirectory, placed inside `tests/ui`. r? ``@jieyouxu``

Try unremapping compiler sources See [#t-compiler/help > Span pointing to wrong file location (`rustc-dev` component)](https://rust-lang.zulipchat.com/#narrow/channel/182449-t-compiler.2Fhelp/topic/Span.20pointing.20to.20wrong.20file.20location.20.28.60rustc-dev.60.20component.29/with/521087083). This PR is a follow-up to rust-lang/rust#141751 regarding the compiler side. Specifically we now take into account the `CFG_VIRTUAL_RUSTC_DEV_SOURCE_BASE_DIR` env from rust-lang/rust#141751 when trying to unremap sources from `$sysroot/lib/rustlib/rustc-src/rust` (the `rustc-dev` component install directory).
