This book was written for use in the introductory compiler course at DIKU, the department of computer science at the University of Copenhagen, Denmark.
At DIKU, the compiler course is taught right after the introductory programming course, which is earlier than in most other universities. Hence, existing textbooks tended either to be too advanced for the level of the course or be too simplistic in their approach, for example only describing a single very simple compiler without bothering too much with the general picture.
This book was written as a response to this and aims at bridging the gap: It is intended to convey the general picture without going into extreme detail about such things as efficient implementation or the newest techniques. It should give the students an understanding of how compilers work and the ability to make simple (but not simplistic) compilers for simple languages. It will also lay a foundation that can be used for studying more advanced compilation techniques, as found e.g. in Advanced Compiler Design and Implementation.
At times, standard techniques from compiler construction have been simplified for presentation in this book. In such cases references are made to books or articles where the full version of the techniques can be found.
The book aims at being "language neutral". This means two things:
- Little detail is given about how the methods in the book can be implemented in any specific language. Rather, the description of the methods is given in the form of algorithm sketches and textual suggestions of how these can be implemented in various types of languages, in particular imperative and functional languages.
