LanguageProject Introduction
Summary
C4 is a remarkable project that implements a functional C compiler and a virtual machine within a single C source file, focusing on clarity and minimalism.
Problem Solved
This project demystifies the complex process of compilation by providing a highly simplified, self-contained, and readable example of a C compiler, making it an excellent educational tool.
Core Features
Minimal C Subset Compiler
Compiles a small but useful subset of the C language.
Integrated Virtual Machine
Includes a built-in virtual machine to execute the generated bytecode directly.
Self-Hosting Capability
The compiler is capable of compiling its own source code, illustrating the concept of self-hosting.
Tech Stack
C
使用场景
While not a production-ready compiler, C4 serves as an invaluable resource in educational and exploratory contexts:
Educational Resource for Compiler Principles
Details
Studying the C4 source code is an excellent way to learn the basic steps involved in compiling a programming language from source to execution.
User Value
Simplifies complex compiler concepts into an easily digestible example.
Platform for Compiler & VM Experiments
Details
Experimenting with modifying or extending the compiler or the virtual machine provides hands-on experience with language implementation.
User Value
Offers a low barrier to entry for hacking on language tools.
