书籍介绍

This book provides the foundation for understanding the theory and pracitce of compilers. Revised and updated, it reflects the current state of compilation. Every chapter has been completely revised to reflect developments in software engineering, programming languages, and computer architecture that have occurred since 1986, when the last edition published. The authors, recognizing that few readers will ever go on to construct a compiler, retain their focus on the broader set of problems faced in software design and software development. Computer scientists, developers, and aspiring students that want to learn how to build, maintain, and execute a compiler for a major programming language.

精彩摘录

"在C++中，一个类的定义可能和它的部分或全部方法的定义分离。因此对于一个和类C相关联的名字x，可能存在一个在它作用域之外的代码区域，然后又跟着一个在它作用域内的代码区域(一个方法定义)。实际上，在这个作用域之内和之外的代码区域可能相互交替，直到所有的方法都被定义完毕。"
"In C++, a class definition may be separated from the definitions of some or all of its methods. Therefore, a name x associated with the class C may have a region of the code that is outside its scope, followed by another region (a method definition) that is within its scope. In fact, regions inside "
"标识符 a 是一个代表了表达式 (x + 1) 的宏。但 x 到底是什么呢？我们不能够静态地解释 x 。"
"Compiler design is full of beautiful examples where complicated real-world problems are solved by abstracting the essence of the problem mathematically. The study of compilers is mainly a study of how we design the right mathematical models and chose the right algorithms, while balacing the eed for "
"我们的目标是：以构造出来的分析树所产生的字符串与输入字符串匹配的方法构造分析树的其余部分。"
"The object is to construct the remainder of the parse tree in such a way that the string generated by the parse tree matches the input string."
"发现错误即停止运行的编译器不是一个好的编译器"
"The use of a rigorous mathematical foundation allows us to show that an optimization is correct and that it produces the desirable effect for all possible inputs."
