Oh god, please no.  Currently at least the RTL parts of GCC still have 
mostly a consistent and obvious style, which is a good thing.  I have no 
idea why anyone would think the above is easier to read than REG_P (x).


Ciao,
Michael.
P.S: Consider this: the current style served us quite well for the last 35 
or so years, so before suggesting style changes, shouldn't you first work 
on the sources for some time?
