OK, what you said sounds reasonable to me.
It makes the code more readable since they are really pure Boolean
functions, and let the functions are precisely same in all archs. But
really, I shall try to prove that it has no negative effect.
e.g. for arc arch. now, I have built the arc raw compiler to build arc
kernel, but excuse me, I plan to finish proof next week, because during
these days, I have to work, buy house, and focus on my father's health.
Thanks.
