IPX's don't have SuperSPARCs, but this comment from lmbench's mhz.c may
help:

 * The sparc specific code is to get around a feature of SuperSPARC
 * that does two adds in one clock.  Apparently, only SuperSPARC does this.
 * Thanks to John Mashey (mash@sgi.com) for explaining SuperSPARC to me.

Mind you, the code only has "#ifdef sparc" and nothing else to
differentiate it from any other sort of sparc...
