Ah, I'm happy to hear that.

OK, here is my take then: longer term, skip_prologue() should become
an identity function.  In the interim, we can continue to use
code-reading based heuristics and debug info to implement it.  The
important point for me is that the routine does not need any special
support from the unwind library.

Of course, this implies that, for the moment, we can't get rid of
code-reading entirely in gdb/ia64, but longer term, we will be able to
do so.
