Compiler Construction Instructor : Dr. Tiayyba Riaz
[email protected] Fall - 2014 Course Code : CS4435 Credit Hours : 3 Class : BS Course Description: CS4435 provides the students with an opportunity to learn issues that arise in the design and construction of translators for programming languages. The course emphasizes techniques that have direct application to the construction of compilers. Not to forget many of the same concepts find application in the implementation of interpreters. Course Objectives: The aim of this module is to show how to apply the theory of language translation introduced in the prerequisite courses to build compilers. This course provide a thorough understanding of the basic structure of compilers for a programming language. A major part of the course consists of the implementation of a compiler for a simplified programming language. Student Learning Outcomes On completion of this unit students should be able to understand: 1. How the compiler works. 2. Phases of the compiler. 3. Implementation details of the compiler phases.
