The long-awaited x64 edition of the bestselling introduction to Intel assembly language.
In the newly revised fourth edition of x64 Assembly Language Step-by-Step: Programming with Linux, author Jeff Duntemann delivers an extensively rewritten introduction to assembly language with a strong focus on 64-bit long-mode Linux assembler. The book offers a lighthearted, robust, and accessible approach to a challenging technical discipline, giving you a step-by-step path to learning assembly code that's engaging and easy to read.
x64 Assembly Language Step-by-Step makes quick work of programmable computing basics, the concepts of binary and hexadecimal number systems, the Intel x86/x64 computer architecture, and the process of Linux software development to dive deep into the x64 instruction set, memory addressing, procedures, macros, and interface to the C-language code libraries on which Linux is built.
Being a programmer is one thing above all else: It is understanding how things work. Learning to be a programmer, furthermore, is almost entirely a process of learning how things work. This can be done at various levels, depending on the tools you're using. If you're programming in Visual Basic, you have to understand how certain things work, but those things are by and large confined to Visual Basic itself. A great deal of machinery is hidden by the layer that Visual Basic places between the programmer and the computer. (The same is true of Delphi, Lazarus, Java, Python, and many other very high-level programming environments.) If you're using a C compiler, you're a lot closer to the machine, so you see a lot more of that machinery—and must, therefore, understand how it works to be able to use it. However, quite a bit remains hidden, even from the hardened C programmer.
If, on the other hand, you're working in assembly language, you're as close to the machine as you can get. Assembly language hides nothing, and withholds no power. The flipside, of course, is that no magical layer between you and the machine will absolve any ignorance and “take care of” things for you. If you don't understand how something works, you're dead in the water—unless you know enough to be able to figure it out on your own.
That's a key point: My goal in creating this book is not entirely to teach you assembly language per se. If this book has a prime directive at all, it is to impart a certain disciplined curiosity about the underlying machine, along with some basic context from which you can begin to explore the machine at its very lowest levels—that, and the confidence to give it your best shot. This is difficult stuff, but it's nothing you can't master given some concentration, patience, and the time it requires—which, I caution, may be considerable.
You'll also find:
• A set of free and open-source development and debugging tools you can download and put to use immediately
• Numerous examples woven throughout the book to illustrate the practical implementation of the ideas discussed within
• Practical tips on software design, coding, testing, and debugging
A one-stop resource for aspiring and practicing Intel assembly programmers, the latest edition of this celebrated text provides readers with an authoritative tutorial approach to x64 technology that's ideal for self-paced instruction
