Introduction
The x86 family has been around for a long time, and as such there are many tricks and techniques that have been discovered and developed that are public knowledge - or maybe not so public. Most of these tricks take advantage of the fact that many instructions effectively do the same thing - but different versions are quicker, or save memory, or don't affect the Flags. Herein are a number of tricks that have been discovered. Each have their Pros and Cons, so should be listed.
Remarks
When in doubt, you can always refer to the pretty comprehensive Intel 64 and IA-32 Architectures Optimization Reference Manual, which is a great resource from the company behind the x86 architecture itsself.
