           Summary: probe process functions defined in shared libraries
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
        AssignedTo: systemtap@sources.redhat.com
        ReportedBy: fche@redhat.com


It would be nice to be able to emulate ltrace to the extent that
we could specify probes on functions that are defined by shared
libraries.  This is probably most easily done by placing uprobes
into the PLT.  A possible syntax would be

   probe process("/bin/foo").function("*").call.plt { }

This should not require debuginfo, except for $parameter access.

See also bug #10787 for the dual (probing the definition sites
within the shared libraries).
See also bug #6880.
