While compilers for high-level programming languages are large complex software systems, they have particular characteristics that differentiate them from other software systems. Their functionality is almost completely well-defined - ideally there exist complete precise descriptions of the source and target languages. Additional descriptions of the interfaces to the operating system, programming system and programming environment, and to other compilers and libraries are often available.   The book deals with the optimization phase of compilers. In this phase, programs are transformed in order to increase their efficiency. To preserve the semantics of the programs in these transformations, the compiler has to meet the associated applicability conditions. These are checked using static analysis of the programs. In this book the authors systematically describe the analysis and transformation of imperative and functional programs. In addition to a detailed description of important efficiency-improving transformations, the book offers a concise introduction to the necessary concepts and methods, namely to operational semantics, lattices, and fixed-point algorithms.   This book is intended for students of computer science. The book is supported throughout with examples, exercises and program fragments.

Das Buch behandelt die Analysephase von Übersetzern für Programmiersprachen. Es beschreibt die lexikalische, die syntaktische und die semantische Analyse, Spezifikationsmechanismen für diese Aufgaben aus der Theorie der formalen Sprachen und automatische Erzeugungsverfahren aus der Theorie der Automaten. Vorgestellt wird eine konzeptionelle Übersetzerstruktur, also eine Aufteilung in eine Menge von Moduln, welche ein Eingabeprogramm in einer Folge von Schritten in ein Maschinenprogramm transformieren, und beschreibt die Schnittstellen zwischen den Moduln. Schließlich werden auch die Strukturen von realen Übersetzern skizziert. Das Buch enthält die notwendige Theorie und Hinweise zur Implementierung.
