971/* This macro allows casting away const-ness to pass -Wcast-qual
972   warnings.  DO NOT USE THIS UNLESS YOU REALLY HAVE TO!  It should
973   only be used in certain specific cases.  One valid case is where
974   the C standard definitions or prototypes force you to.  E.g. if you
975   need to free a const object, or if you pass a const string to
976   execv, et al.  Another valid use would be in an allocation function
977   that creates const objects that need to be initialized.  In some
978   cases we have non-const functions that return the argument
979   (e.g. next_nonnote_insn).  Rather than create const shadow
980   functions, we can cast away const-ness in calling these interfaces
981   if we're careful to verify that the called function does indeed not
982   modify its argument and the return value is only used in a const
983   context.  (This can be somewhat dangerous as these assumptions can
984   change after the fact).  Beyond these uses, most other cases of
985   using this macro should be viewed with extreme caution.  */
