Description Josh Stone 2012-10-11 19:02:48 UTC
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.
