用大量素材向读者展示现实权衡的存在，展示这些选择的影响可能是微妙且深远的。省略由于商业、语言和编译器技术以及町用工具的变迁而变得不太重要的技术、c语言对优化和代码生成提供更深层次的处理。奉书内容分为四部分。前端部分介绍扫描、语法分析、上下文相关分析的内容；基础结构部分阐述中间表示、过程抽象、代码形态为主线的知识；优化部分阐述构建编译器的巾间部分——优化器所出现的问题；代码生成部分着眼于代码生成中的三个主要问题。(Using a large amount of material to show the reader the existence of realistic trade-offs, the impact of these choices may be subtle and far-reaching. Ellipsis technology and C language, which are less important due to changes in business, language and compiler technology and tools, provide deeper processing for optimization and code generation. The contents of the book are divided into four parts. The front part of the scanning, syntax analysis, contextual analysis content; basic structure part of the intermediate representation and knowledge process abstraction, code form as the main part of the construction of compiler optimization; part of the problem -- the towel between the code optimizer; students into three major part of the problem focuses on code generation in.)
