 the optimization is not safe to apply.
 
+There are loop hints that control transformations (e.g. vectorization, loop
+unrolling) and there loop hints that set transformation options (e.g.
+``vectorize_width``, ``unroll_count``).  Pragmas setting transformation options
+imply the transformation is enabled, as if it was enabled via the corresponding
+transformation pragma (e.g. ``vectorize(enable)``). If the transformation is
+disabled  (e.g. ``vectorize(disable)``), that takes precedence over
+transformations option pragmas implying that transformation.
