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