Yeah. I got too many people think that "volatile parameter registers" actually
means something, is understood by many people. I just always have to think a
lot about what the "caller-save" and "callee-save" triply indirect things mean,
so I never use those horrible terms.
And the "volatil" RTL flag usually has nothing to do with "volatile", not in
the C standard sense, and not in this sense either. It is all historical ;-)
