Tuning compilers for it is also a step backwards. In a previous life, I worked on hightly optimizing compilers. Adjusting our product to make one benchmark run better, would make others run worse. I am convinced that compilers tuned for Dhrystone, are in fact badly tuned. We will be doing ourselves a favor by demanding good Specmarks instead of good Dhrystones. -- Don D.C.Lindsay Carnegie Mellon Computer Science
