--- Comment #5 from Michael Catanzaro <mcatanzaro at gnome.org> ---
Mark Lam has confirmed on Slack that this is not something Apple plans to implement, but he's around to offer tips for anyone who wants to try. Mark's suggestions from Slack:

"""
For starters, if you just want to get the asm llint (with no JIT) working, try adding "bti jc \n" to the definition of OFFLINE_ASM_GLOBAL_LABEL in LowLevelInterpreter.cpp.  As the name implies, you’re basically making every global label a viable jump/call target.  That should get you a long way.

Getting the JIT to work will take a lot more work, but is not insurmountable.
