Compiler Development

Compiler Development Skill

This skill provides comprehensive knowledge of building compilers and language implementations using the LLVM infrastructure.

Compiler Architecture Overview

Classic Three-Phase Design

Source Code → Frontend → Middle-End (Optimizer) → Backend → Machine Code
                ↓              ↓                      ↓
             AST/IR      LLVM IR Passes          Target Code

Lexical Analysis

// Token types for a simple language
enum class TokenKind {
    Identifier,
    Number,
    String,
    Keyword,
    Operator,
    Punctuation,
    EndOfFile
};

struct Token {
    TokenKind kind;
    std::string value;
    SourceLocation location;
};
