10. Loop may have been distributed

The contents of the loop may have been distributed over several iterations of the loop. That is, the compiler may have been able to rewrite the body of the loop so that it could be parallelized. However, since this rewriting takes place in the language of the internal representation of the optimizer, it's very difficult to associate the original source code with the rewritten version. For this reason, hints about a distributed loop may refer to line numbers that don't correspond to line numbers in your source code.
