Have you ever wondered what it truly takes to build a compiler from scratch? What happens after you write a line of code? How does your programming language convert it into fast, efficient machine instructions that power everything from mobile apps to space exploration systems? And what if you could not only understand that transformation but build it yourself—from scratch?
LLVM Compiler is more than just another programming manual. It’s a hands-on, thoughtfully written, and emotionally engaging guide designed to walk you through one of the most complex yet rewarding journeys in the world of computer compiler backend development using the LLVM framework.
Through every page, you’ll uncover not just what to do, but why it matters. You’ll build confidence as you learn how to structure target-specific calling conventions, manage code generation, handle instruction selection, design register allocation strategies, and more—all with practical examples and clear, easy-to-understand explanations. Each chapter is designed to build on the last, giving you a continuous sense of progress and clarity.
But this book is more than just instruction—it’s a bridge between theory and application. Compiler development can be intimidating, even overwhelming. That’s why this guide speaks with a human voice, patiently explaining difficult concepts without losing technical accuracy. It's written for real people who want to learn, not just professionals with decades of experience.
INSIDE, YOU WILL How to design and implement backend targets using the LLVM infrastructureHow to create your own instruction definitions, calling conventions, and register filesStep-by-step insights into writing selection DAGs, lowering, and machine code emissionHow to navigate target-specific challenges with confidenceReal examples that go beyond textbook theoryTesting techniques using llvm-lit and integration with the LLVM communityAnd Many More..
There is something incredibly powerful about writing the very instructions that a machine executes. You’re not just building tools—you’re shaping how software interacts with hardware. That’s the kind of influence compiler developers hold.
By the end of this journey, you won’t just understand how LLVM works—you’ll be equipped to build your own compiler backend with purpose and precision. You’ll see every decision in a compiler pipeline as part of a larger, elegant structure. And most importantly, you’ll have the tools and confidence to bring your language ideas to life.
So if you're ready to truly understand what lies beneath your favorite programming language and how code becomes instructions that power the world you’re holding the right guide in your hands.
