This repository contains both x86 (IA-32) and x64 (IA-64) assembly, written on a Mac. Don't expect my programs to compile on other machines.

Some programs are written as C then "compiled" into ASM as an exercise to see what the compiler does at the different optimisation steps.

• Learn x86 and x64 assembly
• Is it hard to write assembly that outperforms the compiler?

The x86-isolated contains an application written without the stdlib. It also have it's own entrypoint, instead of the GCC's.

The web is a nice place, but books are still better:

• Andrew Tanenbaum: Modern Operating Systems, 3rd Edition, 2007. Prentice-Hall. ISBN: 0-13-600663-9

• The Undocumented PC, Frank van Gilluwe, Addison Wesley

• Protected Mode Software Architecture, by Tom Shanley, MindShare, Inc. 1996.
