/* This macro allows casting away const-ness to pass -Wcast-qual
935
   warnings.  DO NOT USE THIS UNLESS YOU REALLY HAVE TO!  It should
936
   only be used in certain specific cases.  One valid case is where
937
   the C standard definitions or prototypes force you to.  E.g. if you
938
   need to free a const object, or if you pass a const string to
939
   execv, et al.  Another valid use would be in an allocation function
940
   that creates const objects that need to be initialized.  In some
941
   cases we have non-const functions that return the argument
942
   (e.g. next_nonnote_insn).  Rather than create const shadow
943
   functions, we can cast away const-ness in calling these interfaces
944
   if we're careful to verify that the called function does indeed not
945
   modify its argument and the return value is only used in a const
946
   context.  (This can be somewhat dangerous as these assumptions can
947
   change after the fact).  Beyond these uses, most other cases of
948
   using this macro should be viewed with extreme caution.  */
