+// Simple tests using MIRI. These are intended only to be a simple exercise of
+// memchr when tests are run under miri. These are mostly necessary because the
+// other tests are far more extensive and take too long to run under miri.
+//
+// These tests are also run when the 'std' feature is not enabled.
