 `(pre_dec:M X)'
      Represents the side effect of decrementing X by a standard amount
      and represents also the value that X has after being decremented.
-     x must be a `reg' or `mem', but most machines allow only a `reg'.
-     m must be the machine mode for pointers on the machine in use.
+     X must be a `reg' or `mem', but most machines allow only a `reg'.

      The amount X is decremented by is the length in bytes of the
      machine mode of the containing memory reference of which this
      expression serves as the address.  Here is an example of its use:
