chibicc is a small yet highly capable C compiler designed to implement most features of the C11 standard while maintaining a clean and educational codebase. It is intended as both a functional compiler and a learning resource, allowing developers to understand how compilers work by reading and studying its implementation. Despite being categorized as a “toy” compiler, it is powerful enough to compile real-world programs such as Git, SQLite, and libpng without modification. The project is structured incrementally, with each commit representing a step in building a full compiler, making it particularly valuable for educational purposes. It includes support for advanced C features such as floating-point types, variable-length arrays, thread-local storage, and atomic operations. Chibicc also provides clear error messages, helping developers understand compilation issues more effectively.
