Everyone knows the dragon book: "Principles of Compiler Design" by Alfred V. Aho and Jeffrey D. Ullman, a milestone in the literature on compiler construction. The new dragon, written by the team of Alfred V. Aho, Ravi Sethi, and Jeffrey D. Ullman and translated by Prof. Dr. Gerhard Barth and his colleagues, provides the same foundational information as the old one, but also addresses the latest research in the field, such as: - Pragmatics of compiler development - syntax-directed translation, type checking, runtime organization, automatic code generation and optimization - a variety of problems and exercises graded by difficulty.
