--- Comment #1 from Mark Wielaard <mjw at redhat dot com> ---
In elfutils-0.156 we decided not to lie about whether or not we knew the
default cfa (cfi state) for a particular abi. See this thread:
http://thread.gmane.org/gmane.comp.sysutils.elfutils.devel/2554
Previously we would just guess and hope for the best (which actually was
normally OKish, so one could say the above was a little paranoid). But we only
had that knowledge for i386 and x86_64.
The backend knowledge has been added upstream for arm, ppc and s390 upstream,
which has been backported for fedora (f20 and f21):
* Fri Sep 06 2013 Mark Wielaard <mjw@redhat.com> 0.156-5
- Add elfutils-0.156-abi_cfi-ppc-s390-arm.patch.
Sets up initial CFI return register, CFA location expression and
register rules for PPC, S390 and ARM (dwarf_cfi_addrframe support).
I'll also create an update for f19.
