+the programmer can explicitly vectorize their code.  While this does not
+guarantee that the generated machine code is efficient, it relieves the
+compiler from determining whether it is legal to vectorize the code, deciding
+whether it is beneficial to do so, and rearranging the code to synthesize
+vector instructions.")
