29.3 Unregistering Code

If code is freed, then the JIT should use the following protocol:

• Remove the code entry corresponding to the code from the linked list.
• Point the relevant_entry field of the descriptor at the code entry.
• Set 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.
