The objective of the course is to give students a deeper perspective into the internals of a compiler. The course equips students with the fundamentals in the theory of program analysis and machine independent code optimizations. The programming assignment in the course will make them expert practitioners of theory thus introduced. The program analysis theory covered in the course is useful in exploring research areas like language-based security, and program correctness.
At the end of the course, students will be able to identify opportunities for optimizing the programs given as input to the compiler, devise strategies to exploit them. The programming assignment focus on implementing program analysis and optimization passes in the Low Level Virtual Machine (LLVM) framework. The code optimization and code generation methods covered in the class will help students implement compiler passes to achieve superior performance on a given hardware.
