Working-in-progress C compiler written in C. My goal is to make it able to self-host.
The mcc compiler follows a standard batch-compiler architecture, consisting of the following components:
- Frontend: lexers and parsers to transform C source file into AST
- IR Generation: Converts the AST into a three-address code intermediate representation.
- Assembly Generation: Translates the intermediate representation into x86-64 assembly code.
mcc invokes gcc for preprocessor, assembler, and linker. Only Linux is supported and tested.
At present, only a small subset of the C language is supported. You can find example programs demonstrating the compiler’s capabilities in the test/test_data directory. Additionally, mcc does not yet implement any optimization and currently produces extremely inefficient code with no regard for performance.
