LegoFuzz: Interleaving Large Language Models for Compiler Testing
Yunbo Ni · 2025
Using large language models (LLMs) to test compilers is promising but faces two major challenges: the generated programs are often too simple, and large-scale testing is costly. We present a new framework that splits the process into an offline phase—where LLMs generate small, diverse code pieces—and an online phase that assembles them into complex test programs.
