Hmm, I'm not sure that's true. hppa has been supported by gcc for
over ten years; from the gcc 2.0 release notes:
Note that the type hppa currently works only with Berkeley
systems, not with HP/UX.
Some other nuggets of information: gcc managed to do a better job of
implementing spin_lock() than it was (or is!) possible for me to do
in inlin assembler. One of the first ports converted to the new DFA
pipeline model was the PA port; i386 & sparc were done later.
