I can change it to O1 if preferred. I prefer that front end tests should test what the front end does. The front end does not perform optimizations, the optimizer does. So the front end tests should not include optimization options (even though I do realize that adding -O<N> reduces the size of the produced code). There is no need to add unnecessary churn in front end tests if the optimizer changes.
