IRFusion - Intermediate Language Compiler

🚀 Overview

IRFusion is a signature-level educational compiler prototype that compiles a simple high-level pseudo language to clean, readable C code through an intermediate representation (IR).

🔧 Features

• Custom lexer and parser (recursive descent)
• AST and SSA-style Intermediate Representation
• Clean C backend code generation
• Modular design with professional structure
• Unit-tested and extensible
