This book provides the foundation for understanding the theory and practice of compilers.Revised and updated with new chapters on Programming Language Semantics and Undefined Behaviour Semantics, the title addresses modern issues in compiler design. However, 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.Features -Covers important topics such-as context-free grammars, fine state machines, and syntax-directed translationPresents the five methods for translation to explain syntax-directed translationIllustrates new techniques for data-flow analysis that emphasize the unity of code optimization and other program analysis softwareUses code optimization to work with parallel machinesExplains just-in-time compiling with programming languages such as JavaIncludes online video lectures to enhance learning experience
