Modern X86 Assembly Language Programming. 2nd Ed

 Modern X86 Assembly Language Programming, Second Edition is an edifying text about x86 64-bit (x86-64) assembly language programming. The book’s content and organization are designed to help you quickly understand x86-64 assembly language programming and the computational resources of Advanced Vector Extensions (AVX). It also contains an abundance of source code that is structured to accelerate learning and comprehension of essential x86-64 assembly language constructs and SIMD programming concepts. After reading and using this book, you’ll be able to code performance-enhancing functions and algorithms using x86-64 assembly language and the AVX, AVX2, and AVX-512 instruction sets.

 Before proceeding I should explicitly mention that this book does not cover x86-32 assembly language programming. It also doesn’t discuss legacy x86 technologies such as the x87 floating-point unit, MMX, and Streaming SIMD Extensions. The first edition remains relevant if you’re interested in learning about these topics. This book does not explain x86 architectural features or privileged instructions that are used in operating systems. However, you will need to thoroughly understand the material that’s presented in this book to develop x86 assembly language code for use in an operating system.

 While it is still theoretically possible to write an entire application program using assembly language, the demanding requirements of contemporary software development make such an approach impractical and ill advised. Instead, this book concentrates on coding x86-64 assembly language functions that are callable from C++. Each source code example was created using Microsoft Visual Studio C++ and Microsoft Macro Assembler (MASM).
