This is misleading. It only means that there exists loop bound threshold either defined by the user or calculated with the cost model. It does not mean that the cost model's decision is that the vectorization is not profitable. I am adding this to our cleanup todo list. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37194
