well, i think you can try it and see the effect. we can
use the __attribute__ thing with configuration script.
however, no one has even made GG_INLINE yet...

from computational point of view, it is the same. there are
differences: you cannot access the two lowest bytes of it
(like AL and AH in EAX). it is also often used in string
commands (e.g. memory copying or scanning or sequential
loading). but you can multiply it and use in other arithmetic
operations (and in addressing) as the other 7 registers.
