+  deterministically. Note that Miri still uses host floats for some operations, so behavior can
+  still differ depending on the host target and setup.
 * `-Zmiri-disable-isolation` disables host isolation. As a consequence,
   the program has access to host resources such as environment variables, file
   systems, and randomness.
