Based on what I recall happening here at Stratus, that's not the way
they go about it; basically, IBM said "Hey, you!  Prove that your compiler
doesn't use our patented technique!" and one of our senior compiler
engineers was forced to sit down with some IBM $%*&!@ and go through
how our compiler does register allocation.  Nice, huh?  So much for
innocent until proven guilty.
