[RFC] DWARF CFI: what to do with .eh_frame sections?

[Mark Kettenis]

It's clear that we want to support unwinding using info in .eh_frame
sections in addition to .debug_frame sections.  I'm inclined to make
to make dwarf-frame.c provide two frame unwinders: one that uses
.debug_frame info, and one that uses .eh_frame info.  That way it will
be possible to let the target determine if .dwarf_frame will be
preferred over .eh_frame or not.

Thoughts?
