Magellan: Autonomous Discovery of Novel Compiler Optimization Heuristics with AlphaEvolve (opens in new tab)

arXiv:2601.21096v1 Announce Type: new Abstract: Modern compilers rely on hand-crafted heuristics to guide optimization passes. These human-designed rules often struggle to adapt to the complexity of modern software and hardware and lead to high maintenance burden. To address this challenge, we present Magellan, an agentic framework that evolves the compiler pass itself by synthesizing executable C++ decision logic. Magellan couples an LLM coding agent with evolutionary search and autotuning ...
