Become familiar with the LLVM infrastructure and start using LLVM libraries to design a compiler.

LLVM is currently the point of interest for many firms, and has a very active open source community. It provides us with a compiler infrastructure that can be used to write a compiler for a language. It provides us with a set of reusable libraries that can be used to optimize code, and a target-independent code generator to generate code for different backends. It also provides us with a lot of other utility tools that can be easily integrated into compiler projects.

This book details how you can use the LLVM compiler infrastructure libraries effectively, and will enable you to design your own custom compiler with LLVM in a snap.

We start with the basics, where you'll get to know all about LLVM. We then cover how you can use LLVM library calls to emit intermediate representation (IR) of simple and complex high-level language paradigms. Moving on, we show you how to implement optimizations at different levels, write an optimization pass, generate code that is independent of a target, and then map the code generated to a backend. The book also walks you through CLANG, IR to IR transformations, advanced IR block transformations, and target machines.

By the end of this book, you'll be able to easily utilize the LLVM libraries in your own projects.


Learn:
✓ Get an introduction to LLVM modular design and LLVM tools
✓ Convert frontend code to LLVM IR
✓ Implement advanced LLVM IR paradigms
✓ Understand the LLVM IR Optimization Pass Manager infrastructure and write an optimization pass
✓ Absorb LLVM IR transformations
✓ Understand the steps involved in converting LLVM IR to Selection DAG
✓ Implement a custom target using the LLVM infrastructure
✓ Get a grasp of C's frontend clang, an AST dump, and static analysis

Features:
✓ Learn to use the LLVM libraries to emit intermediate representation (IR) from high-level language
✓ Build your own optimization pass for better code generation
✓ Understand AST generation and use it in a meaningful way

Who this book is for:
This book is intended for those who already know some of the concepts of compilers and want to quickly get familiar with the LLVM infrastructure and the rich set of libraries that it provides.
