DO NOT USE THIS UNLESS YOU REALLY HAVE TO! It should 1147 only be used in certain specific cases. One valid case is where 1148 the C standard definitions or prototypes force you to. E.g. if you 1149 need to free a const object, or if you pass a const string to 1150 execv, et al. Another valid use would be in an allocation function 1151 that creates const objects that need to be initialized. In some 1152 cases we have non-const functions that return the argument 1153 (e.g. next_nonnote_insn). Rather than create const shadow 1154 functions, we can cast away const-ness in calling these interfaces 1155 if we're careful to verify that the called function does indeed not 1156 modify its argument and the return value is only used in a const 1157 context.
