Large Language Models for Compiler Optimization
Summary: Researchers have developed a 7B-parameter transformer model for optimizing LLVM assembly code size. The model predicts instruction counts before and after optimization and the optimized code itself. It achieves a 3.0% improvement in reducing instruction counts over the compiler and generates compilable code 91% of the time, perfectly emulating the compiler's output 70% of the time.

CatalaLang/catala: Programming language for law specification
Summary: Catala is a domain-specific programming language designed for deriving algorithms from legislative texts, ensuring code-law faithfulness. Developed in collaboration with law professionals, Catala's logical structure mirrors that of law, embedding default logic as a core feature. The language allows users to annotate legislative text with code, derive an implementation of socio-fiscal mechanisms, and generate lawyer-readable PDFs. The Catala compiler is available as an opam package, with additional plugin backends for Python and OCaml.
