Engineering a Compiler, Third Edition is full of technical updates, new material covering the latest developments in compiler technology, and a fundamental change in the presentation of the middle section of the book, with new chapters focusing on semantic elaboration (the problems that arise in generating code from the ad-hoc syntax-directed translation schemes in a generated parser), on runtime support for naming and addressability, and on code shape for expressions, assignments, and control-structures. Leading educators and researchers Keith Cooper and Linda Torczon have revised their popular text with a fresh approach to learning important techniques for constructing a modern compiler, combining basic principles with pragmatic insights from their own experience building state-of-the-art compilers. Presents in-depth treatment of algorithms and techniques used in the front end of a modern compiler Pays particular attention to code optimization and code generation, the primary areas of recent research and development New chapters in the middle section of the book focus on how compilers (and interpreters) implement abstraction, tying the underlying knowledge to students’ own experience and to the languages in which they have been taught to program Chapter 13 on register allocation has been fully re-written to focus on bottom-up methods of register allocation at the local scope
