Do you mean you're going to remove EH entirely from the old JIT?  If so, I'll complain ;).

As you pointed out earlier the EH bits are useful for stack frames on x86_64.  In particular, to get useful stack traces from gdb with JIT'ed code those EH frames need to be there.  So even if other people don't currently set JITExceptionHandling for this purpose (I do in a few projects), they probably will when they see crashes.
