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.
