`tests/ui`: A New Order [8/N] Some `tests/ui/` housekeeping, to trim down number of tests directly under `tests/ui/`. Part of rust-lang#133895.
…useZ4 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`

…lways, r=Kobzol Rename run always This PR renames run_always to run_to_dry_run for better clarity, making the field's purpose more explicit and avoiding confusion with command caching behavior. r? `@Kobzol`
