Professional Assembly Language
Every high level language program (such as C and C++) is converted by a compiler into assembly language before it is linked into an executable program. This book shows you how to view the assembly language code generated by the compiler and understand how it is created. With that knowledge you can tweak the assembly language code generated by the compiler or create your own assembly language routines.
This code-intensive guide is divided into three sections — basics of the assembly language program development environment, assembly language programming, and advanced assembly language techniques. It shows how to decipher the compiler-generated assembly language code, and how to make functions in your programs faster and more efficient to increase the performance of an application.
What you will learn from this book:
- The benefits of examining the assembly language code generated from your high-level language program
- How to create stand-alone assembly language programs for the Linux Pentium environment
- Ways to incorporate advanced functions and libraries in assembly language programs
- How to incorporate assembly language routines in your C and C++ applications
- Ways to use Linux system calls in your assembly language programs
- How to utilize Pentium MMX and SSE functions in your applications
About the Author
Richard Blum has worked for a large U.S. government organization for more than 15 years. During that time, he has had the opportunity to program utilities in various programming languages: C, C++, Java, and Microsoft VB.NET and C#. With this experience, Rich has often found the benefit of reviewing assembly language code generated by compilers and utilizing assembly language routines to speed up higher-level language programs.
Rich has a bachelor of science degree in electrical engineering from Purdue University, where he worked on many assembly language projects. (Of course, this was back in the eight-bit processor days.) He also has a master of science degree in management from Purdue University, specializing in Management Information Systems.

Good at explaining the basics
By Yuri Slobodyanyuk
About the syntax used - yes,through all the book only the AT&T assembly syntax is used. The obvious reason is that most popular compiler on Linux is GCC, which has GAS (GNU Assembler) as the behind the scenes assembler invoked by GCC every time you compile your code. And native to GAS is the AT&T syntax and not the Intel syntax, which is deemed more readable.
Now to the book contents. As there is no previous knowledge of assembly assumed, the reader is first given a quite detailed view of the Intel processors architecture, including coverage of modern features like the Netburst design, present in modern Pentium series processors.Then basics of the tools of the trade are presented.
With this preliminary knowledge the reader is prepared to begin the major part of the book - the assembly language itself.
The learning curve is flattened as much as possible by the author, guiding us through all the major domains of assembly programming - working with processor registers, stack and heap manipulation, floating point arithmetic,handling various data types (strings, integers, floating point numbers) and more.
All the chapters contain stand alone code examples ready to be compiled and run. Most of the example code is 30-40 lines long and relates to the particular point being explained, i.e. there's no intentional cross-reference between code samples in different chapters.
Starting at the chapter 12, "Linux System Calls", begins what this book was written for - how to apply gathered so far knowledge to the real world. This includes: inline assembly in C/C++ code, programs combining C/C++ source code
and assembly functions, writing static/dynamic libraries in assembly that can be used by any high-level language (here C/C++), optimization tips and tricks, how to work with files.
Finally, the last chapter deals with advanced features like MMX, SSE, and SSE2 instructions .
So, to conclude - It has all a
programmer never exposed to assembly needs to learn to start writing fully functional stand alone or integrated into high-level language assembly code . The author covers all fundamentals of assembly programming and he does it in a plain and accessible language.
However there's something you should be aware of - if you're (like me) a fan of the Wrox "Professional.." series,- don't misunderstand the word in this context. It is only an introductory text on assembly,and it will not bring you to the level of professional assembly programmer, yet.

Explains the trivial, misses the essentials; Not for those who REALLY want to learn Assembly Language.
By Paco Garcia
The reason why I bought this book was because I have loved some of the books published by Wrox for years and I thought that I could use this book to learn the essentials of Assembly Language and what I can do with it. As with all books from all publishers, there will always be some "hits" and "misses". Unfortunately, for Wrox (and for me), this is one of the "misses" for me.
Let me start off with the title; this is NOT worthy of the "Professional" moniker of Wrox's series. I have read some books of Wrox which did deserve the moniker, and the content and the essentials were in the right places. This book in particular is somewhat of a "Beginning Assembly Language with Less Significant Information" moniker, to be more precise.
Here are a couple of examples from the book that I absolutely abhor:
A. Lack of explanation in the right places, but supposedly is explained elsewhere.
In page 77, in the "The Sample Program" section, the author has the reader's attention, in what will hopefully be some code with more than sufficient explanation. I was extremely disappointed when I read this right after the last line of code (my emphasis in CAPS included):
"This program uses quite a few different assembly language instructions. FOR NOW, DON'T WORRY TOO MUCH ABOUT WHAT THEY ARE; THAT WILL BE DESCRIBED IN DETAIL IN SUBSEQUENT CHAPTERS. FOR NOW, CONCENTRATE ON HOW THE INSTRUCTIONS ARE PLACED IN THE PROGRAM, THE FLOW OF HOW THEY OPERATE, AND HOW THE SOURCE CODE FILE IS CONVERTED INTO AN EXECUTABLE PROGRAM FILE."
I was flabbergasted. Why would the author put in so much non-essential code in a demo program when he will simply tell us to skip the "few different assembly language instructions"?
First of all, if the author wanted to demonstrate a simple program where he wants us to focus on "how the instructions are placed in the program, the flow of how they operate, and how the source code file is converted into an executable program file", then a classic "Hello, world" example where the text "Hello world" is printed on the terminal screen would have been more than sufficient for this program. I did not understand how the flow of how the program operated until I explicitly researched it on the internet. I did NOT learn the flow of the program from this book. This only led to more questions than answers, e.g.
"Why did he put that much numbers of the letter 'x' in the ascii variable"?,
"Why did he call the cpuid program like that? Isn't there a call keyword needed?",
"Where did that 42 value come from, and why is he moving it to the EDX register? Why not the ECX register or any other registers? Why did it have to be the EDX register? Why did he use 42 as the value? Did he just magically think of a random number and decided on 42 and put it in the register?"
Another example can be found in page 103. It is more of the same thing. Here's an excerpt after some sample code which supposedly demonstrates how to use indexed memory locations:
"Don't worry too much about the auxiliary code used in this example. All of these instructions are covered in later chapters. Concentrate on how the program manipulates the data array defined."
First of all, what, for the author, is considered 'auxiliary' code? If these are going to be covered in later chapters, please specify where so we can fold the page, look them up and go back to the topic. Like the previous example, this demo program leaves more questions than answers, e.g.
"What is 'nop'? What is its use? Why is it there?"
"What is 'cmpl'? Does it stand for 'complain'? Because that is exactly what I am doing."
"What is jne loop?"
B. No lack of explanation to more trivial contents
Turn to page 24 of the book and you will learn about the Retirement Unit and Execution Unit. Turn to the next page and you learn about Low-latency Integer Execution unit and Complex-integer execution unit. Flip through the pages and you can see definitions of flags and registers, but no explanation when, how or why use them; there isn't even a note on whether or not we are going to use them. Instead, the reader is given classic textbook "An elevator is something that elevates" definitions - a list of terms which are described, but nothing more. Definitions are OK, but when are we going to use all of these? If we're not going to use it in code or if it is not going to serve a purpose later on in the book (which should be stated if that were the case, by the way), why even bother bringing it up? It's like reading a book on the essentials of C and a whole chapter is dedicated to the history of the B programming language, an almost-extinct programming language which would be superseded by C, which is entirely beside the point of learning the essentials of C. The worst part of this is that it's not just one chapter dedicated to this - as you read along, you will find trivial information such as
Here are my suggestions to improve this book. First, remove "Professional" in the title. It is NOT professional. Go with "Beginning" because it suits it more. Another suggestion is to make do without the trivial information, and focus on explaining anything and everything essential in Assembly Language. When I learn a language, I want all explanations about a demo program's code within 2 pages, and the reasoning for choosing the values and registers. The third and my final suggestion is to comment on EVERY LINE OF CODE. I'm serious. This is assembly language, the world of mnemonics and concatenated words, not C or some other high level language, where keywords which can be easily understood by humans are used.
There are more questions than answers as you try to follow along the code of this book. If you want to learn Assembly Language, look for another book elsewhere.

programmer_in_santamonica
By Roy Fine
This book should not carry the word Professional in the title - it is basic - very basic at best. This book is all about the Intel architecture - e.g. Intel processors. The target audience for this book - as stated in the introduction - is C/C++ programmers interested in converting their (Linux) C/C++ programs to assembly language. Consider this book if you know nothing of assembly language and you want to play around with it in a Linux on Intel hardware environment. Do not buy this book if you are interested in writing anything more advanced than simple hello world real mode apps. More specifically - do not buy this book if your are interested in writing IA-32 protected mode code - none of those things are covered in the book.
