本书将带领读者从头开始制作一门语言的编译器。笔者特意为本书设计了CЬ语言，CЬ可以说是C语言的子集，实现了包括指针运算等在内的C语言的主要部分。本书所实现的编译器就是C Ь语言的编译器， 是实实在在的编译器，而非有诸多限制的玩具。另外，除编译器之外，本书对以编译器为中心的编程语言的运行环境，即编译器、汇编器、链接器、硬件、运行时环境等都有所提及，介绍了程序运行的所有环节。(This book will lead the reader to make a language compiler from the beginning. The book is designed specifically for the C language can be said to have stood, C is a subset of C language, the realization of the main part including pointer arithmetic, C language. The book is the C language compiler have a compiler that is real in the compiler, and there are many restrictions of toys. In addition, in addition to the compiler, book on compiler centric programming language runtime environment, the compiler, assembler, linker, hardware and runtime environment are mentioned, introduces all aspects of the program run.)
