x64 Assembly Language Step-by-Step

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.

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.

  Klappentext

  An engaging and essential update of the bestselling introduction to Intel assembly language Assembly language is where the program code meets the silicon. Nevertheless, most beginners and many software engineers struggle with assembly, instead relying on high-level languages to do the job. In this fourth edition of x64 Assembly Language Step-by-Step: Programming with Linux, celebrated author Jeff Duntemann delivers a completely rewritten introduction to assembly language focused on 64-bit long-mode under Linux. The author covers computing and programming basics, binary and hexadecimal number bases, the x64 architecture, and the process of Linux software development. Along the way you'll get hands-on experience with the x64 instruction set, memory addressing, procedures, macros, and interfacing to the C library functions upon which Linux is built. The book is lighthearted, robust, and accessible, offering a step-by-step path to assembly coding that covers the bases while being easy to read. You'll learn the free NASM assembler and debugging tools you can download and use immediately, along with numerous code examples throughout the book. You'll also get practical tips on software design, coding, testing, and debugging that will sharpen your assembly programming skills. x64 Assembly Language Step-by-Step: Programming with Linux, 4th Edition, is an authoritative tutorial to Intel/AMD x64 technology that's perfect for self-paced instruction. This latest edition will cement the book's reputation as the gold standard for x64 assembly language introductions.
