LLVM-Harness: AI Tool for Compiler Bug Fixing
Researchers have unveiled llvm-harness, a pioneering tool aimed at helping large language model (LLM) agents comprehend and rectify compiler errors. This innovation targets the middle end of LLVM, a prominent compiler framework. Key components of llvm-harness include LLVM tools designed for agents, a benchmark named llvm-bench featuring 334 reproducible middle-end bugs, and a specialized mini agent called llvm-autofix-mini for automated bug resolution. An evaluation of five leading models revealed a performance drop when addressing compiler bugs using current methodologies. This initiative tackles the distinct challenges posed by compiler bugs, which demand extensive cross-domain knowledge and often come with vague, sparse reports. The research paper can be found on arXiv with the identifier 2603.20075.
