linux system call

Documents the journey from C code to assembly to machine code very nicely.

This was originally written for the Phil Inch's Game Developer's Magazine and after getting lots of positive feedback I expanded and improved it. I have spent a lot of time working on this and would appreciate hearing from you if you like it.

An old book teaching the basics of assembly programming including explanations for the beginner of binary numbers etc.

x86 64-bit assembly

x86-64 amd64 assembly

An introduction to programming in 64-bit assembly for x86 chips.

(he's) writing a series of tutorials on x86 assembly for C programmers who are already familiar with many of the basics of programming and computing.

Im 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 arent doing it for me, and I need something organized the way I think, on the topics Im interested in, presented in a way which make comprehensive understanding easy. Ill do the work, go find the answers, and then drop everything here for you to enjoy.

Impressive.

As an exercise, I want to write a Hello World program in C simple enough that I can disassemble it and be able to explain all of the assembly to myself. This should be easy, right? [...]

Nice article about compiling "Hello World" without libc under linux. Suprisingly deep digging necessary to get it to run properly.

"Hello, world" without libc

As an exercise, I want to write a Hello World program in C simple enough that I can disassemble it and be able to explain all of the assembly to myself.

<GeDaMo> Use mmap rather than malloc if you want memory with nx disabled: http://androidbutnotparanoid.blogspot.com/2009/05/dynamically-generating-and-executing.html

Computer programs can generate machine code in memory and then execute it. This is the case with Sun's Java Hotspot VM, which dynamically compiles Java bytecode to native code to increase the VM's performance. Several exploits are based on buffer overflows to remotely inject machine code into memory and then jumping into it. Google released it's Chrome web browser featuring the V8 Javascript Engine, which greatly improved Javascript's performance by compiling Javascript to native code.
