These groups are a great way for new contributors to get involved as they provide a stream of tasks focused around one area and have designated channels for help and advice. Here is a list of areas where work is being carried on: Name Short Description Code Zulip Stream Async-await Implementation Implementing async-await Link #wg-async Diagnostics Use crates.io crates for diagnostics rendering and make emitting diagnostics nicer. rustc_errors, rustc_lint, annotate-snippets #t-compiler/diagnostics LLVM Working with LLVM upstream to represent Rust in its development rustc, LLVM #t-compiler/llvm MIR Optimizations Write MIR optimizations and refactor the MIR to be more optimizable. MIR transform #t-compiler/mir-opts Parallel-rustc Making parallel compilation the default for rustc rustc #t-compiler/parallel-rustc Polonius Exploring the integration of the “NLL 2.0”-like “Polonius analysis” into rustc borrow check, rust-lang/polonius, rust-lang/datafrog #t-types/polonius RLS 2.0 Experimenting with a new compiler architecture tailored for IDEs rust-analyzer #t-compiler/rust-analyzer Rust Compiler Development Guide Make the compiler easier to learn by ensuring that rustc-dev-guide is “complete” rustc, rustc-dev-guide #t-compiler/rustc-dev-guide Enzyme Expose experimental LLVM features for GPU offloading Project Goal #wg-autodiff Linker Helping deal with linker related issues and their integration within the compiler - #wg-linker For historical record here’s a list of Working Groups that are not active anymore (either because they reached their goals or because work stalled): Name Short Description Zulip Stream Meta How compiler team organizes itself #z-archived-t-compiler/wg-meta Non-Lexical Lifetimes (NLL) Implementing non-lexical lifetimes #z-archived-t-compiler/wg-nll Polymorphization Implement an analysis to detect when functions can remain polymorphic during code generation. #z-archived-t-compiler/wg-polymorphization Prioritization Triaging regressions, mainly deciding if there are potential release blockers #t-compiler/prioritization Profile-Guided Optimization Implementing profile-guided optimization for rustc #z-archived-t-compiler/wg-profile-guided-optimization RFC 2229 Make a closure capture individual fields of the variable rather than the entire composite variable #z-archived-t-compiler/wg-rfc-2229 Rustc pipelining Enable Cargo to invoke rustc in a pipelined fashion, speeding up crate graph compiles. #z-archived-t-compiler/wg-pipelining Self-Profile Improving the -Z self-profile feature #z-archived-t-compiler/wg-self-profile Traits Improving the trait-system design + implementation #z-archived-t-compiler/wg-traits
