Preface

LLVM is one of the very hot topics in recent times. It is an open source project with an ever-increasing number of contributors. Every programmer comes across a compiler at some point or the other while programming. Simply speaking, a compiler converts a high-level language to machine-executable code. However, what goes on under the hood is a lot of complex algorithms at work. So, to get started with compiler, LLVM will be the simplest infrastructure to study. Written in object-oriented C++, modular in design, and with concepts that are very easy to map to theory, LLVM proves to be attractive for experienced compiler programmers and for novice students who are willing to learn.

As authors, we maintain that simple solutions frequently work better and are easier to grasp than complex solutions. Throughout the book we will look at various topics that will help you enhance your skills and drive you to learn more.

We also believe that this book will be helpful for people not directly involved in compiler development as knowledge of compiler development will help them write code optimally.
