You are right... It makes no sense to have a "benchmark" which does not give numbers. Now I understand what you mean, I can try to add the `run-flags` directive to `compiletest`.

I think that `run-flags` would also be useful for other benchmarks in the directory, which at this moment do not give any numbers. Some of them are meant to be run as normal programs (such as the `shootout-*` ones) so this does not apply to them, but there are others (such as `core-std`) which do a Bencher-like testing. What do you think about it?
