--- Comment #6 from Mark Millard <marklmi26-fbsd at yahoo.com> ---
Head no longer has the old libunwind code and my
understanding is that there is no plan to complete
the implementation of DW_CFA_remember_state and
DW_CFA_restore_state in 11 or 12 (which still have
the old libunwind code as I understand).

clang also has progressed so that in head, and
eventually 13.0, clang will be officially the
means of building powerpc families (64-bit and
32-bit), using llvm's libunwind.

The 64-bit ABI has also been changed as part of
the activity.
