Compilers are at the heart of everything programmers do, yet even experienced developers find them intimidating. For those eager to truly grasp how compilers work, Writing a C Compiler dispels the mystery. This book guides you through a fun and engaging project where you’ll learn what it takes to compile a real-world programming language to actual assembly code.
Writing a C Compiler will take you step by step through the process of building your own compiler for a significant subset of C—no prior experience with compiler construction or assembly code needed. Once you’ve built a working compiler for the simplest C program, you’ll add new features chapter by chapter. The algorithms in the book are all in pseudocode, so you can implement your compiler in whatever language you like. Along the way, you’ll explore key concepts like:
Lexing and parsing: Learn how to write a lexer and recursive descent parser that transform C code into an abstract syntax tree. Program analysis: Discover how to analyze a program to understand its behavior and detect errors. Code generation: Learn how to translate C language constructs like arithmetic operations, function calls, and control-flow statements into x64 assembly code. Optimization techniques: Improve performance with methods like constant folding, dead store elimination, and register allocation.
Compilers aren’t terrifying beasts—and with help from this hands-on, accessible guide, you might even turn them into your friends for life.
I assume you’re already sold on the idea of writing a compiler—you did pick up this book, after all. I want to talk a little bit about why we’re writing a compiler for C in particular. The short answer is that C is a (relatively) simple language, but not a toy language. At its core, C is simple enough to implement even if you’ve never written a compiler before. But it’s also a particularly clear example of how programming languages are shaped by the systems they run on and the people who use them. Some aspects of C vary based on what hardware you’re targeting; others vary between operating systems; still others are left unspecified to give compiler writers more flexibility. Some bits of the language are historical artifacts that have stuck around to support legacy code, while others are more recent attempts to make C safer and more reliable.
Who This Book Is For: I wrote this book for programmers who are curious about how compilers work. Many books about compiler construction are written as textbooks for college or graduate-level classes, but this one is meant to be accessible to someone exploring the topic on their own. You won’t need any prior knowledge of compilers, interpreters, or assembly code to complete this project. A basic understanding of computer architecture is helpful, but not essential; I’ll discuss important concepts as they come up and occasionally point you to outside resources with more background information. That said, this is not a book for novice programmers. You should be comfortable writing substantive programs on your own, and you should be familiar with binary numbers, regular expressions, and basic data structures like graphs and trees. You’ll need to know C well enough to read and understand small C programs, but you don’t need to be an expert C programmer. We’ll explore the ins and outs of the language as we go.
Although this book is geared toward newcomers to the subject, it will also be worthwhile for people who have some experience with compilers already. Maybe you implemented a toy language for a college class or personal project, and now you’d like to work on something more realistic. Or maybe you’ve worked on interpreters in the past, and you want to try your hand at compiling programs down to machine code. If you’re in this category, this book will cover some material you already know, but it will provide plenty of new challenges too. At the very least, I promise you’ll learn a few things about C.
