This is an old lecture I had in my assembly language programming class (CS 301) and I just thought to put it up here just in case anyone wants to learn assembly.

http://www.cs.uaf.edu/2005/fall/cs301/lecture/

Also from the site a gcc x86 cheat sheet
http://www.cs.uaf.edu/2005/fall/cs301/support/x86/index.html

For x86-64 the x86-64 whitepaper

If you have any questions about what is said in the lectures please ask.

Maybe also make this topic a assembly program collaberation.
