...is the fastest string search function:

The best part is that it takes advantage of free unaligned access in x86. Try doing that with your braindead RISCs!

If x86 was really CISC, it would have a single instruction to do this like the VAX's MATCHC.

Notice how this doesn't specify an algorithm so it is entirely left up to the implementation and can even vary depending on the lengths of the strings.
