Compilers: Principles, Techniques and Tools, known to professors, students, and developers worldwide as the "Dragon Book," is available in a new edition. 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. New chapters include: Chapter 10 Instruction-Level ParallelismChapter 11 Optimizing for Parallelism and LocalityChapter 12 Interprocedural AnalysisIntroduces the theory and practice of compiler design. Covers topics like context-free grammars, fine state machines, and syntax-directed translation.
