This entirely revised second edition of Engineering a Compiler is full of technical updates and new material covering the latest developments in compiler technology. In this comprehensive text you will learn important techniques for constructing a modern compiler. Leading educators and researchers Keith Cooper and Linda Torczon combine basic principles with pragmatic insights from their experience building state-of-the-art compilers. They will help you fully understand important techniques such as compilation of imperative and object-oriented languages, construction of static single assignment forms, instruction scheduling, and graph-coloring register allocation. - In-depth treatment of algorithms and techniques used in the front end of a modern compiler - Focus on code optimization and code generation, the primary areas of recent research and development - Improvements in presentation including conceptual overviews for each chapter, summaries and review questions for sections, and prominent placement of definitions for new terms - Examples drawn from several different programming languages

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.

This work can be viewed as a study of the effectiveness of inlining in modern optimizing compilers. We discovered that, with optimizing FORTRAN compilers, (1) object code growth from inlining is substantially smaller than source code growth, (2) compile time growth from inlining is smaller than source code growth, and (3) the compilers we tested were not able to capitalize consistently on the opportunities presented by inlining."

Abstract: "We describe two improvements to Chaitin-style graph coloring register allocators. The first, optimistic coloring, uses a stronger heuristic to find a k-coloring for the interference graph. The second extends Chaitin's treatment of rematerialization to handle a larger class of values. These techniques are complimentary. Optimistic coloring increases the number of procedures that color without spilling and lowers total spill costs when spilling is unavoidable. Rematerialization lowers the cost of spilling some values. This paper describes both the techniques themselves and our experience building and using register allocators that incorporate them. It provides a detailed description of optimistic coloring and rematerialization. It presents experimental data to show the performance of several versions of the register allocator on a suite of FORTRAN programs. It discusses several insights that we discovered only after repeated implementation of these allocators."
