To get the most out of this book
This book is designed to bring you the latest features of LLVM, so we encourage you to use LLVM after version 12.0, or even the development branch – that is, the main branch – throughout this book.
We assume that you are working on Linux or Unix systems (including macOS). Tools and sample commands in this book are mostly run in the command-line interface, but you are free to use any code editors or IDEs to write your code.
In Chapter 1, Saving Resources on Building LLVM, we will provide details on how to build LLVM from source.
If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
