Automatically Synthesizing Verifiable C Code via LLM-driven Evolution
This analysis explores a novel LLM-driven evolutionary search framework, AutoICE, designed to synthesize verifiable C code from natural language requirements. AutoICE significantly improves verification success rates by leveraging diverse individual initialization, collaborative crossover, and self-reflective mutation to mitigate errors and discover implicit knowledge.
Executive Impact & Key Metrics
AutoICE demonstrates a robust capability to enhance software correctness and reliability, significantly outperforming existing state-of-the-art methods in generating verifiable C code, especially from developer-friendly, concise requirements.

AutoICE: A Framework for Verifiable C Code Synthesis
AutoICE frames the synthesis task as an evolutionary process, integrating large language models with logical verifiers. This approach balances exploration and exploitation, enabling LLMs to uncover implicit knowledge and progressively generate high-quality, verifiable code.

Case Study: Mitigating Hallucination in ACSL Specifications
In a specific instance from the FM-BENCH-DF dataset, two parent codes (par1 and par2) are analyzed. Par1 successfully passes Frama-C but fails WP due to missing preconditions and loop variants. Par2 also fails both verifiers due to invalid syntax in ACSL annotations (e.g., valid_read_only instead of \valid_read and --> instead of ==>).
Through collaborative crossover, offspring off1 is generated. It learns from par2's correct precondition (requires n > 0) and loop variant (loop variant n - i;) while correcting par1's inaccurate interval bounds in the loop invariant to 0 <= i <= n. This demonstrates how crossover combines valid insights and corrects errors.
For another instance, an individual off initially fails WP verification due to missing loop invariant clauses, indicated by an error message. Using self-reflective mutation, the LLM analyzes the verification report and correctly introduces additional loop invariant clauses, such as \forall integer j; 0 <= j < i ==> a[j] <= max; and \exists integer j; 0 <= j < i && max == a[j];, enabling the mutated individual off' to pass full verification. This highlights the mutation's ability to diagnose and resolve inconsistencies autonomously.
