Learn LLVM 17
Learn how to build and use the complete spectrum of real-world compilers, including the frontend, optimization pipeline, and a new backend by leveraging the power of LLVM core libraries Key Features Get to grips with using LLVM libraries step by step Understand the high-level design of LLVM compilers and apply these principles to your own compiler Add a new backend to target an unsupported CPU architecture Purchase of the print or Kindle book includes a free PDF eBook Book DescriptionLLVM was built to bridge the gap between the theoretical knowledge found in compiler textbooks and the practical demands of compiler development. With a modular codebase and advanced tools, LLVM empowers developers to build compilers with ease. This book serves as a practical introduction to LLVM, guiding you progressively through complex scenarios and ensuring that you navigate the challenges of building and working with compilers like a pro. The book starts by showing you how to configure, build, and install LLVM libraries, tools, and external projects. You’ll then be introduced to LLVM's design, unraveling its applications in each compiler stage: frontend, optimizer, and backend. Using a real programming language subset, you'll build a frontend, generate LLVM IR, optimize it through the pipeline, and generate machine code. Advanced chapters extend your expertise, covering topics such as extending LLVM with a new pass, using LLVM tools for debugging, and enhancing the quality of your code. You'll also focus on just-in-time compilation issues and the current state of JIT-compilation support with LLVM. Finally, you’ll develop a new backend for LLVM, gaining insights into target description and how instruction selection works. By the end of this book, you'll have hands-on experience with the LLVM compiler development framework through real-world examples and source code snippets.What you will learn Configure, compile, and install the LLVM framework Understand how the LLVM source is organized Discover what you need to do to use LLVM in your own projects Explore how a compiler is structured, and implement a tiny compiler Generate LLVM IR for common source language constructs Set up an optimization pipeline and tailor it for your own needs Extend LLVM with transformation passes and clang tooling Add new machine instructions and a complete backend Who this book is for This book is for compiler developers, enthusiasts, and engineers new to LLVM. C++ software engineers looking to use compiler-based tools for code analysis and improvement, as well as casual users of LLVM libraries who want to gain more knowledge of LLVM essentials will also find this book useful. Intermediate-level experience with C++ programming is necessary to understand the concepts covered in this book.
LLVM Code Generation

Release Date: 2025-05-23
Explore the world of code generation with the LLVM infrastructure, and learn how to extend existing backends or develop your own Get With Your Book: PDF Copy, AI Assistant, and Next-Gen Reader Free Key Features Understand the steps involved in generating assembly code from LLVM IR Learn the key constructs needed to leverage LLVM for your hardware or backend Strengthen your understanding with targeted exercises and practical examples in every chapter Book DescriptionThe 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.
Build Your Own Programming Language

Publisher: Packt Publishing Ltd
Release Date: 2024-01-31
Learn to design your own programming language in a hands-on way by building compilers, using preprocessors, transpilers, and more, in this fully-refreshed second edition, written by the creator of the Unicon programming language. Purchase of the print or Kindle book includes a free PDF eBook Key Features Takes a hands-on approach; learn by building the Jzero language, a subset of Java, with example code shown in both the Java and Unicon languages Learn how to create parsers, code generators, scanners, and interpreters Target bytecode, native code, and preprocess or transpile code into a high-level language Book DescriptionThere are many reasons to build a programming language: out of necessity, as a learning exercise, or just for fun. Whatever your reasons, this book gives you the tools to succeed. You’ll build the frontend of a compiler for your language and generate a lexical analyzer and parser using Lex and YACC tools. Then you’ll explore a series of syntax tree traversals before looking at code generation for a bytecode virtual machine or native code. In this edition, a new chapter has been added to assist you in comprehending the nuances and distinctions between preprocessors and transpilers. Code examples have been modernized, expanded, and rigorously tested, and all content has undergone thorough refreshing. You’ll learn to implement code generation techniques using practical examples, including the Unicon Preprocessor and transpiling Jzero code to Unicon. You'll move to domain-specific language features and learn to create them as built-in operators and functions. You’ll also cover garbage collection. Dr. Jeffery’s experiences building the Unicon language are used to add context to the concepts, and relevant examples are provided in both Unicon and Java so that you can follow along in your language of choice. By the end of this book, you'll be able to build and deploy your own domain-specific language.What you will learn Analyze requirements for your language and design syntax and semantics. Write grammar rules for common expressions and control structures. Build a scanner to read source code and generate a parser to check syntax. Implement syntax-coloring for your code in IDEs like VS Code. Write tree traversals and insert information into the syntax tree. Implement a bytecode interpreter and run bytecode from your compiler. Write native code and run it after assembling and linking using system tools. Preprocess and transpile code into another high-level language Who this book is for This book is for software developers interested in the idea of inventing their own language or developing a domain-specific language. Computer science students taking compiler design or construction courses will also find this book highly useful as a practical guide to language implementation to supplement more theoretical textbooks. Intermediate or better proficiency in Java or C++ programming languages (or another high-level programming language) is assumed.
