Summary
This article explores compiler construction by building a simple compiler from scratch, covering all major phases of compilation.
Pipeline phases:
- Lexing: Source → Tokens
- Parsing: Tokens → AST
- Semantic Analysis: Type checking
- IR Generation: AST → Intermediate Representation
- Optimization: Constant folding, dead code elimination
- Code Generation: IR → Assembly
Understanding compilers helps write better code, debug more effectively, and design languages.
