Decoding the Magic of Compilers
A comprehensive exploration of compiler optimization techniques and how they transform your code for maximum performance.
About This Book
This book demystifies the inner workings of modern compilers, focusing on the optimization techniques that transform human-written code into highly efficient executable programs. Whether you're a software developer seeking to write more compiler-friendly code, a computer science student diving deeper into compiler theory, or a performance enthusiast wanting to understand what happens behind the scenes, this resource will provide valuable insights.

How to Use This Book
This book is designed to be read sequentially from start to finish, as later chapters build upon concepts introduced in earlier ones. However, each chapter also stands on its own as a reference for specific optimization topics.
The code examples are presented in C/C++ for clarity and portability, but the principles apply to most compiled languages.
