Optimizing Compilers For Modern Architectures A Dependence Based Approach

Modern computer architectures designed with high-performance microprocessors offer tremendous potential gains in performance over previous designs. Yet their very complexity makes it increasingly difficult to produce efficient code and to realize their full potential. This landmark text from two leaders in the field focuses on the pivotal role that compilers can play in addressing this critical issue. The basis for all the methods presented in this book is data dependence, a fundamental compiler analysis tool for optimizing programs on high-performance microprocessors and parallel architectures. It enables compiler designers to write compilers that automatically transform simple, sequential programs into forms that can exploit special features of these modern architectures. The text provides a broad introduction to data dependence, to the many transformation strategies it supports, and to its applications to important optimization problems such as parallelization, compiler memory hierarchy management, and instruction scheduling. The authors demonstrate the importance and wide applicability of dependence-based compiler optimizations and give the compiler writer the basics needed to understand and implement them. They also offer cookbook explanations for transforming applications by hand to computational scientists and engineers who are driven to obtain the best possible performance of their complex applications. The approaches presented are based on research conducted over the past two decades, emphasizing the strategies implemented in research prototypes at Rice University and in several associated commercial systems. Randy Allen and Ken Kennedy have provided an indispensable resource for researchers, practicing professionals, and graduate students engaged in designing and optimizing compilers for modern computer architectures. * Offers a guide to the simple, practical algorithms and approaches that are most effective in real-world, high-performance microprocessor and parallel systems. * Demonstrates each transformation in worked examples. * Examines how two case study compilers implement the theories and practices described in each chapter. * Presents the most complete treatment of memory hierarchy issues of any compiler text. * Illustrates ordering relationships with dependence graphs throughout the book. * Applies the techniques to a variety of languages, including Fortran 77, C, hardware definition languages, Fortran 90, and High Performance Fortran. * Provides extensive references to the most sophisticated algorithms known in research.

"Modern Compiler Design" makes the topic of compiler design more accessible by focusing on principles and techniques of wide application. By carefully distinguishing between the essential (material that has a high chance of being useful) and the incidental (material that will be of benefit only in exceptional cases) much useful information was packed in this comprehensive volume. The student who has finished this book can expect to understand the workings of and add to a language processor for each of the modern paradigms, and be able to read the literature on how to proceed. The first provides a firm basis, the second potential for growth.

"Embedded Computing is enthralling in its clarity and exhilarating in its scope. If the technology you are working on is associated with VLIWs or "embedded computing", then clearly it is imperative that you read this book. If you are involved in computer system design or programming, you must still read this book, because it will take you to places where the views are spectacular. You don't necessarily have to agree with every point the authors make, but you will understand what they are trying to say, and they will make you think.” From the Foreword by Robert Colwell, R&E Colwell & Assoc. Inc The fact that there are more embedded computers than general-purpose computers and that we are impacted by hundreds of them every day is no longer news. What is news is that their increasing performance requirements, complexity and capabilities demand a new approach to their design. Fisher, Faraboschi, and Young describe a new age of embedded computing design, in which the processor is central, making the approach radically distinct from contemporary practices of embedded systems design. They demonstrate why it is essential to take a computing-centric and system-design approach to the traditional elements of nonprogrammable components, peripherals, interconnects and buses. These elements must be unified in a system design with high-performance processor architectures, microarchitectures and compilers, and with the compilation tools, debuggers and simulators needed for application development. In this landmark text, the authors apply their expertise in highly interdisciplinary hardware/software development and VLIW processors to illustrate this change in embedded computing. VLIW architectures have long been a popular choice in embedded systems design, and while VLIW is a running theme throughout the book, embedded computing is the core topic. Embedded Computing examines both in a book filled with fact and opinion based on the authors many years of R&D experience. Features: · Complemented by a unique, professional-quality embedded tool-chain on the authors' website, http://www.vliw.org/book · Combines technical depth with real-world experience · Comprehensively explains the differences between general purpose computing systems and embedded systems at the hardware, software, tools and operating system levels. · Uses concrete examples to explain and motivate the trade-offs.

The goal of An Introduction to the Theory of Optimizing Compilers is to give the reader a solid understanding of modern optimizing compilers. The theory is focused on* control flow graphs, including algorithms for computing dominance, dominance frontiers, and control dependence,* static single assignment form (SSA form) including recent advances intranslation from SSA form based on fast liveness checking and coalescing, and* loop transformations.We also cover instruction scheduling and register allocation. The optimization techniques we present include constant propagation with conditional branches, partial redundancy elimination, hash-based and global value numbering, operator strength reduction, dead code elimination, control flow graph simplification based on postdominators, translation from SSA form based on coalescing, unimodular loop transformations, modulo scheduling, and iterative register coalescing.The book is to a high degree self-contained and is intended to be suitable both for self-study and university courses. For completeness we provide a review of fundamentals, including sections on sets and relations, graphs, number theory, and some linear algebra.New in this extended first edition is performance measurements on POWER using SPEC CPU2000. We compare gcc, clang and the author's ISO validated C99 compiler.PrerequisitesThe reader is assumed to have studied algorithms and data structures, but no knowledge about compiler front-ends is necessary.About the authorDr. Jonas Skeppstedt has done research on optimizing compilers and multicore computer architecture in Lund, Chalmers, and USC in Los Angeles; his lmpcc compiler was rewarded ISO C certification in 2003 for C99; has taught optimizing compilers at Lund University for many years and has developed safety-critical C code for the new European Rail Traffic Management System (ERTMS), andhelped German lawyers as expert witness on the C programming language.

This new, expanded textbook describes all phases of a modern compiler: lexical analysis, parsing, abstract syntax, semantic actions, intermediate representations, instruction selection via tree matching, dataflow analysis, graph-coloring register allocation, and runtime systems. It includes good coverage of current techniques in code generation and register allocation, as well as functional and object-oriented languages, that are missing from most books. In addition, more advanced chapters are now included so that it can be used as the basis for a two-semester or graduate course. The most accepted and successful techniques are described in a concise way, rather than as an exhaustive catalog of every possible variant. Detailed descriptions of the interfaces between modules of a compiler are illustrated with actual C header files. The first part of the book, Fundamentals of Compilation, is suitable for a one-semester first course in compiler design. The second part, Advanced Topics, which includes the advanced chapters, covers the compilation of object-oriented and functional languages, garbage collection, loop optimizations, SSA form, loop scheduling, and optimization for cache-memory hierarchies.
