Compilers: principles, techniques, & tools = 编译原理: 技术与工具

Compilers: Principles, Techniques, & Tools, often dubbed the "Dragon Book" due to its distinctive cover art, is a seminal text in computer science that lays the foundational framework for understanding the principles and construction of compilers. The book is renowned for its comprehensive approach to the theory and practical applications of compiler design. This introduction offers an insightful dive into its content, significance, and impact in the field of computer science.

Detailed Summary of the Book

The "Dragon Book" extensively covers the entire process of compiler construction, presenting a detailed division of the complexities involved. It begins with lexical analysis, which involves tokenizing the source code into meaningful symbols. This is followed by syntax analysis, which checks the source code against grammatical rules to ensure structural correctness. The book progresses into semantic analysis, where it examines the meaning of the syntactically correct phrases in the context of the language.

After establishing a foundation in these preliminary stages, the book delves into intermediate code generation, optimization strategies, and finally, the generation of target code. Each phase is explored with in-depth theoretical discourse backed by practical techniques and algorithms. The "Dragon Book" is renowned for its rigorous mathematical treatment of algorithms involved in compiler design, supporting readers with precise proofs and derivations.

The book also incorporates discussions on code optimization techniques, which are vital for improving the efficiency and performance of the resulting code. It elaborates on both local and global optimization processes and delves into areas like loop optimization, data-flow analysis, and register allocation. Furthermore, the text explores advanced topics such as type checking, run-time environments, and garbage collection, offering a holistic understanding of modern compiler design.
