Unlock the Power Behind Every Line of Code You Run. Learn What Happens After You Hit 'Compile'. Are you fascinated by how code turns into lightning-fast machine instructions? Have you ever wondered how modern compilers actually generate code behind the scenes? Whether you're a curious beginner or a developer looking to build serious compiler skills, this book is your ultimate guide to mastering LLVM backend development. LLVM is one of the most powerful and widely used compiler frameworks in the world. It powers everything from programming languages like Swift and Rust to performance-critical systems at companies like Apple, Google, and Intel. Yet, its backend-the part that turns intermediate code into real machine instructions-remains one of its most complex and least understood areas. This book will change that. Inside, you'll learn: ✅ How LLVM transforms high-level code into fast, efficient machine instructions ✅ The step-by-step process of writing your own backend from scratch ✅ Key concepts like SSA, ABI, instruction selection, and register allocation-explained simply ✅ The difference between SelectionDAG and GlobalISel, and how to work with both ✅ How to model your architecture using TableGen and plug it into the LLVM pipeline ✅ Real-world strategies for debugging, optimizing, and understanding every stage of backend compilation ✅ How to contribute meaningfully to the LLVM open-source community ✅ The essential tools and tips to avoid common mistakes and grow your compiler expertise Whether you're a compiler engineer, systems programmer, language creator, or just curious about how things work under the hood, this guide is packed with clear explanations, practical examples, and hands-on exercises to deepen your understanding of one of the most complex and exciting areas in computer science. You don't need a PhD to understand compilers. You just need the right guide. This is it.

Publisher: Packt Publishing Ltd
Release Date: 2025-05-27
Written by Frank Vasquez, an embedded Linux expert, this new edition enables you to harness the full potential of Linux to create versatile and robust embedded solutions All formats include a free PDF and an invitation to the Embedded System Professionals community Key Features Learn how to develop and configure reliable embedded Linux devices Discover the latest enhancements in Linux 6.6 and the Yocto Project 5.0, codename Scarthgap Explore different ways to debug and profile your code in both user space and the Linux kernel Purchase of the print or Kindle book includes a free PDF eBook Book DescriptionMastering Embedded Linux Development is designed to be both a learning resource and a reference for your embedded Linux projects. In this fourth edition, you'll learn the fundamental elements that underpin all embedded Linux projects: the toolchain, the bootloader, the kernel, and the root filesystem. First, you will download and install a pre-built toolchain. After that, you will cross-compile each of the remaining three elements from scratch and learn to automate the process using Buildroot and the Yocto Project. The book progresses with coverage of over-the-air software updates and rapid prototyping with add-on boards. Two new chapters tackle modern development practices, including Python packaging and deploying containerized applications. These are followed by a chapter on writing multithreaded code and another on techniques to manage memory efficiently. The final chapters demonstrate how to debug your code, whether it resides in user space or in the Linux kernel itself. In addition to GNU debugger (GDB), the book also covers the different tracers and profilers that are available for Linux so that you can quickly pinpoint any performance bottlenecks in your system. By the end of this book, you will be able to create efficient and secure embedded devices with Linux that will delight your users.What you will learn Cross-compile embedded Linux images with Buildroot and Yocto Enable Wi-Fi and Bluetooth connectivity with a Yocto board support package Update IoT devices securely in the field with Mender or balena Prototype peripheral additions by connecting add-on boards, reading schematics, and coding test programs Deploy containerized software applications on edge devices with Docker Debug devices remotely using GDB and measure the performance of systems using tools like perf and ply Who this book is for If you are a systems software engineer or system administrator who wants to learn how to apply Linux to embedded devices, then this book is for you. The book is also for embedded software engineers accustomed to programming low-power microcontrollers and will help them make the leap to a high-speed system-on-chips that can run Linux. Anyone who develops hardware for Linux will find something useful in this book. But before you get started, you will need a solid grasp of the POSIX standard, C programming, and shell scripting.
