Next: Custom Debug Info, Previous: Registering Code, Up: JIT Interface
If code is freed, then the JIT should use the following protocol:
relevant_entry field of the descriptor at the code entry.
     action_flag to JIT_UNREGISTER and call
__jit_debug_register_code. 
If the JIT frees or recompiles code without unregistering it, then gdb and the JIT will leak the memory used for the associated symbol files.
