Rafael, could you mention in a few words the role these "EH bits"
serve for the legacy JIT? What is the meaning/impact of removing them?
- i.e. what will stop working? Given that there's still need of the
legacy JIT to be around, what is the advantage of removing this code,
at the expense of losing existing functionality?
