|
|
|
|
<p>If code is freed, then the JIT should use the following protocol:
|
|
</p>
|
|
<ul>
|
|
<li> Remove the code entry corresponding to the code from the linked list.
|
|
|
|
</li><li> Point the <code>relevant_entry</code> field of the descriptor at the code entry.
|
|
|
|
</li><li> Set <code>action_flag</code> to <code>JIT_UNREGISTER</code> and call
|
|
<code>__jit_debug_register_code</code>.
|
|
</li></ul>
|
|
|
|
<p>If the JIT frees or recompiles code without unregistering it, then <small>GDB</small>
|
|
and the JIT will leak the memory used for the associated symbol files.
