Researchers introduce C* language to integrate formal verification into C programming
Hacker News reports researchers developed C*, a language integrating verification into C through embedded proof code.
The short version
- Researchers introduced C*, an extension of C that incorporates verification capabilities using a symbolic execution engine and an LCF-style proof kernel.[Hacker News]
- The system allows developers to embed proof blocks directly alongside code to support real-time, interactive verification.[Hacker News]
- A prototype was evaluated on small C benchmarks and the attach function of pKVM's buddy allocator, successfully handling complex reasoning tasks.[Hacker News]
Key facts
- C* is a proof-integrated language design that extends C with verification capabilities powered by a symbolic execution engine and an LCF-style proof kernel.[Hacker News]
- The language enables real-time verification by allowing developers to embed proof blocks alongside implementation code.[Hacker News]
- Researchers evaluated a prototype on benchmark C programs and the attach function of pKVM's buddy allocator, reporting success across various idioms and reasoning tasks.[Hacker News]
