             Bug #: 14703
           Summary: Add runtime/dyninst support for symbols & backtracing
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dyninst
        AssignedTo: systemtap@sourceware.org
        ReportedBy: jistone@redhat.com
    Classification: Unclassified


The dyninst runtime currently lacks any symbol resolution or backtrace
functions.

I'm not sure how much this is possible, with all the rewriting that dyninst
does to the process.  I'm not aware of any mutatee-side APIs to help out here. 
But for the first level uaddr(), at least, the pt_regs are currently passing
the original PC location.  We might also be able to inspect live unwind info,
especially if Dyninst's fix for PR14702 updates the appropriate sections.
