We use it; I'm not sure that's the same as need. ;-)
Lots of the uses that I examined should use a mechanism
like arm does for recording syndrome data in the unwind slots.
Quite possibly the only legitimate use is sparc, where it
has an alternate address space that reads with execute permission.
We could probably find a different way to accomplish that
if we removed the *_code helpers.
