An educational software system of a tiny self-compiling C compiler
...The Selfie Project provides an educational platform for teaching undergraduate and graduate students the design and implementation of programming languages and runtime systems. The focus is on the construction of compilers, libraries, operating systems, and even virtual machine monitors. The common theme is to identify and resolve self-reference in systems code which is seen as the key challenge when teaching systems engineering, hence the name. Selfie is implemented in a single (!) file and kept minimal for simplicity. ...
8cc C Compiler is a small and educational C compiler designed to support the C11 standard while maintaining a compact and easy-to-understand codebase. It was created as a hobby project with the goal of demonstrating how a compiler works internally, making it a valuable resource for learning compiler design. The project includes core components such as a lexer, parser, and preprocessor, allowing users to explore each stage of the compilation process. One of its notable features is its ability...
