Unfortunately, gcc is no longer the best choice for high-performance
computing.  gcc does not understand neither the ultrasparc pipeline
nor the pentium. Even more unfortunately, adapting gcc to those
processors is a major effort (take the pgcc project), and it will be
even worse for the next generation of processors....
