So, it makes sense to me for the ARM EHABI  implementation to be in its own Unwind-ehabi.c file and do not use libunwind under it.  This was part of why I thought of EHABI as being a different unwinder than the zero-cost unwinder in terms of _LIBUNWIND_BUILD_blah.

Since the way we developed this was sharing code with the itanium implementation as much as possible, are you okay with upstreaming it in this fashion and then looking at moving it away in the future?
Can you be more specific about what you mean by “in this fashion” and “moving it away in the future”.
