Exactly. Part of what you want to see is that GCC optimizes well for the new
machine, i.e., that there aren't artifacts of the machine description that get
in the way of optimization.
So you'd want to use applications that are good exercises not just of the code
generator but also the optimizer. Dhrystone isn't really that, because it has
evolved into mostly an optimizer test, not a machine or code generator test.
