2025-07-08Add target maintainer information for mips64-unknown-linux-muslabi64Jens Reidel-1/+51
The mips64-unknown-linux-muslabi64 target is currently rather broken, but I'm working on getting it fixed so that it can at least be used again. While I can't commit to maintaining the LLVM side of this target, I don't mind looking into any other MIPS or musl-related issues that arise with this target.

2025-07-07Update intro blurb in `wasm32-wasip1` docsAlex Crichton-25/+23
I was reading over this documentation in light of the effort to enlist more maintainers for Tier 2 targets and figured it was time for a refresh of this documentation now that historical renames/etc have all become a thing of the past. No new major changes to this documentation, mostly just wanted to update it and reflect the modern status quo for this target.

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.

2025-06-25Rollup merge of #142809 - KMJ-007:ad-type-analysis-flag, r=ZuseZ4Jana Dönszelmann-0/+2
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```

Tweak `-Zmacro-stats` measurement. It currently reports net size, i.e. size(output) - size(input). After some use I think this is sub-optimal, and it's better to just report size(output). Because for derive macros the input size is always 1, and for attribute macros it's almost always 1. r? ```@petrochenkov```
2025-06-24Rollup merge of #138780 - trifectatechfoundation:loop_match_attr, ↵Jubilee-0/+52
r=oli-obk,traviscross Add `#[loop_match]` for improved DFA codegen tracking issue: https://github.com/rust-lang/rust/issues/132306 project goal: https://github.com/rust-lang/rust-project-goals/issues/258 This PR adds the `#[loop_match]` attribute, which aims to improve code generation for state machines. For some (very exciting) benchmarks, see https://github.com/rust-lang/rust-project-goals/issues/258#issuecomment-2732965199 Currently, a very restricted syntax pattern is accepted. We'd like to get feedback and merge this now before we go too far in a direction that others have concerns with. ## current state We accept code that looks like this ```rust #[loop_match] loop { state = 'blk: { match state { State::A => { #[const_continue] break 'blk State::B } State::B => { /* ... */ } /* ... */ } } } ``` - a loop should have the same semantics with and without `#[loop_match]`: normal `continue` and `break` continue to work - `#[const_continue]` is only allowed in loops annotated with `#[loop_match]` - the loop body needs to have this particular shape (a single assignment to the match scrutinee, with the body a labelled block containing just a match) ## future work - perform const evaluation on the `break` value - support more state/scrutinee types ## maybe future work - allow `continue 'label value` syntax, which `#[const_continue]` could then use. - allow the match to be on an arbitrary expression (e.g. `State::Initial`) - attempt to also optimize `break`/`continue` expressions that are not marked with `#[const_continue]` r? ``@traviscross``
