5 阶段编译流水线: 词法分析 → 语法分析(Pratt) → 语义分析(类型推断) → LLVM IR → .exe 模块: - lexer: 手写状态机, 40 种 Token, // 和 /* */ 注释 - parser: Pratt 表达式解析(9 级优先级) + 递归下降语句/函数 - ast: 14 种节点类型 + 工厂函数 - sema: 作用域链符号表 + 类型推断 + 类型检查 - codegen: AST → LLVM-C API, print_i64/f64/bool 内建 - driver: 命令行 + 流水线串联 + 错误报告 - util: Arena bump allocator (8MB) 测试: 65 单元测试(词法41+语法15+语义9) + 5 集成测试 全部通过 语言特性: i64/f64/bool/void, let不可变变量, if/else, while, 递归函数
