On what code? Any code you pick is an arbitrary benchmark. There are infinite number of context free grammars you could feed the compiler and for any of them in might make some unknown optimization X that is superior to all other compilers. The number of programs that you can write are infinite therefore you cannot say for certain that is better or worse for all programs, or in other words, objectively say it is terrible.

The idea that you need to test with infinite inputs to be "objective" is preposterous. You can in fact test with one input and the result is still objective, and you can conclude that it is objectively terrible or not on that one input. In reality, a suite of real world tests within your application domain provides actual useful information -- those aren't arbitrary benchmarks if that's the actual code you care about.
