I posted x86 Assembly for C Programmers 1 to reddit and got some great feedback. There were a few things that were brought up, and I’m taking a minute to address some of them (I’m not addressing everything).  Thanks to everyone out there who took the time to point out mistakes and make suggestions.

Introduction

I’m writing a series of tutorials on x86 assembly for C programmers who are already familiar with many of the basics of programming and computing. The assembly tutorials available online just aren’t doing it for me, and I need something organized the way I think, on the topics I’m interested in, presented in a way which make comprehensive understanding easy. I’ll do the work, go find the answers, and then drop everything here for you to enjoy.

Please note I do not claim to be an expert on the assembly language.

My interest in assembly is for both optimizing C applications, and the purpose of developing exploits for vulnerabilities in common applications, not write applications in assembly from scratch. I’m not interested in, “Good,” examples of assembly, I’m interested in real examples. This will affect the assembly we look at. More specifically, I write the code in C, compile it with gcc, and what comes out is what we’ll be dissecting.

For the purposes of these tutorials, 32-bit x86 assembly. Everything compiled/built/disassembled on the latest stable distro of Ubuntu. More…
