Book Description
The LLVM infrastructure is a popular compiler ecosystem widely used in the tech industry and academia. This technology is crucial for both experienced and aspiring compiler developers looking to make an impact in the field. Written by Quentin Colombet, a veteran LLVM contributor and architect of the GlobalISel framework, this book provides a primer on the main aspects of LLVM, with an emphasis on its backend infrastructure; that is, everything needed to transform the intermediate representation (IR) produced by frontends like Clang into assembly code and object files.

You'll learn how to write an optimizing code generator for a toy backend in LLVM. The chapters will guide you step by step through building this backend while exploring key concepts, such as the ABI, cost model, and register allocation. You'll also find out how to express these concepts using LLVM's existing infrastructure and how established backends address these challenges. Furthermore, the book features code snippets that demonstrate the actual APIs.

By the end of this book, you'll have gained a deeper understanding of LLVM. The concepts presented are expected to remain stable across different LLVM versions, making this book a reliable quick reference guide for understanding LLVM.

What you will learn
Understand essential compiler concepts, such as SSA, dominance, and ABI
Build and extend LLVM backends for creating custom compiler features
Optimize code by manipulating LLVM's Intermediate Representation
Contribute effectively to LLVM open-source projects and development
Develop debugging skills for LLVM optimizations and passes
Grasp how encoding and (dis)assembling work in the context of compilers
Utilize LLVM's TableGen DSL for creating custom compiler models
Who this book is for
This book is for both beginners to LLVM and experienced LLVM developers. If you're new to LLVM, it offers a clear, approachable guide to compiler backends, starting with foundational concepts. For seasoned LLVM developers, it dives into less-documented areas such as TableGen, MachineIR, and MC, enabling you to solve complex problems and expand your expertise. Whether you're starting out or looking to deepen your knowledge, this book has something for you.
