To get the most out of this book

You will need to have an understanding of C++, especially C++17, which is used for LLVM and throughout the examples in the book. The provided examples are assumed to be run on a Unix-like operating system, with Linux and Darwin (Mac OS) being considered the operating system requirements for the book. We will use Git to clone the LLVM source tree and start working on it. Some tools also need to be installed, such as CMake and Ninja, which will be actively used to build the examples and the LLVM source code.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
