Engineering a Compiler, Third Edition covers the latest developments in compiler technology, 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 this 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 treatments of algorithms and techniques used in the front end of a modern compilerPays particular attention to code optimization and code generation, both primary areas of recent research and developmentFocuses 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 programCovers bottom-up methods of register allocation at the local scope
