>From what I can tell, this is not testing anything about arith is it? Seems like this is all about testing "vector.print" in itself, or even just the testing runtime we have.
Can you try to make the file location more relevant?

Can we also consolidate all the testing for the runtime in a single execution? (each new lit test isn't free: it'll fork/exec a compiler process, and then execute the result here).
