+                       Format: {slow | fast | unsupported}
+                       Allow skipping scalar unaligned access speed tests. This
+                       is useful for testing alternative code paths and to skip
+                       the tests in environments where they run too slowly. All
+                       CPUs must have the same scalar unaligned access speed.
