Computer Science projects increasingly involve the analysis of unstructured textual data. Yet, only a small minority of CS grads are proficient in text-processing with regular expressions and grammars, or have used parsing/transformation tools such as sed, AWK, Lex and Yacc. Students can address this gap by taking this course. Moreover, by understanding the process of code translation and optimization, students can become better at writing efficient code.
Compilers is my favorite subject because it harnesses the beauty of theoretical computer science to solve very concrete software engineering problems. Time and again, it demonstrates how efficient software implementations can be automatically generated from compact, high-level specifications. Compilers also offers a perspective on how research results find their way into practice. Much of the course material originates from research papers written in the 70s and 80s that have since been put into practice.
Modern compilers are among the most complex pieces of software around. Through this course, students learn how to break down this complexity --- how to modularize their design, how to make the modules flexible and extensible, how to decouple design and implementation, and finally, how to build efficient implementations. This course will also provide significant experience in OO-programming with C++. Modern C++ is the language of choice for writing high-performance code. While retaining some of the key benefits of C-language such as the ability to write low-level code, it avoids most of C's drawbacks such as the lack of type-safety, standardized libraries for data structures, and modern features such as objects, templates (aka generics), type inference, closures, exceptions, and so on.

We will use the "Dragon book" --- Compilers: Principles, Techniques, and Tools, Second Edition by Aho, Sethi, Ullman, and Lam, or any older version; including the 1977 version, called "Principles of Compiler Design" and has a green dragon on it, as opposed to the purple dragon on the latest version. We will use the textbook for material that has not changed significantly since the green dragon book. Your reference for newer material will be the lecture slides and additional material made available from this page.
The weighting for programming assignments, midterm and final exams will be roughly as follows. Note that these weightings are preliminary, and are subject to some changes in the future.
You are advised to start working on the projects at the earliest possible time even if the deadlines are far away. The date the projects are due will be clearly specified. Projects are due by 11:59pm on the specified date. Late projects will be penalized at the rate of 5% for the first day, 15% the second day and 25% per day after that. So, there is no point submitting a project more than 4 days late! No further extensions will be allowed.
Each student gets one late pass that allows you to submit one assignment up to 4 days late. Use the late pass wisely. I will not accept more than one late submission for any reason, including emergencies.
Any form of copying in the course, and all forms of academic dishonesty, are considered serious offenses, and will be prosecuted to the maximum extent permitted by university policies. The minimum penalty for any form of copying, whether from your friends, the Internet or outside sources, or from previous offerings of the course, will be an F-grade. There will be no exceptions.
Note that we make use of automated software for catching copies, and this software is quite sophisticated and can see through typical evasion attempts. In addition, we manually check for unusual similarities among programs. These enhanced may not be performed on every submission, but if we do identify copying, then it is a situation of "one strike and you are out," i.e., you end up with an F-grade regardless of how well you have done in the course until then.
If you have special needs, concerns or a disability, please contact the staff at Student Accessibility Support Center (SASC). SASC staff will review your concerns and determine, with you, what accommodations are necessary and appropriate. All information and documentation will remain confidential.
