Hi Corey,

Are there any plans to add support to libunwind for the case when only
.debug_frame sections are present?

Can't speak for others, but I myself do not have plans for this.  As I
recall, I considered it briefly, but decided against it.  I think part
of it was that the info in .debug_frame isn't exactly the same as in
the .eh_frame sections.



I ask this knowing that the default switches for building Linux these
days includes -fexceptions, however many user apps will not have this
switch set.


As an aside, for the Frysk developers out there:

Is there some reliance on the -fasynchronous-unwind-tables switch being
used to compile the app-under-test besides getting libunwind to work?
In other words, are there other parts of Frysk that rely on .eh_frame

Thanks for your consideration,

- Corey
