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.
