What to optimize:
-----------------
If you plan to do non-x86 architecture specific optimizations (SIMD normally),
-then take a look in the i386/ directory, as most important functions are

already optimized for MMX.
If you want to do x86 optimizations then you can either try to finetune the
-stuff in the i386 directory or find some other functions in the C source to

architecture-specific versions. It is recommended to look at older
revisions of the interesting files (for a web frontend try ViewVC at

Alternatively, look into the other architecture-specific versions in

comprehend the instructions, it could help understanding the functions
and how they can be optimized.
