We vectorize loops with FP inductions and FP reductions under the "fast-math". The main point here that the FP induction is a "secondary", the tripcount does not depends on it. I think it's OK to use FP induction outside the loop, why not? FP reduction, that we allow today, actually means using the result value outside.
