[Bug translator/14737] plt.return probes

--- Comment #2 from Frank Ch. Eigler <fche at redhat dot com> ---
This capability remains undone.  It would require something like:

- tapsets.cxx register_plt_variants() should register some TOK_RETURN
alternatives
- tapsets.cxx query_one_plt() should look for that TOK_RETURN, and map such
  probes to .statement().return synthetic probes
- elsewhere nearby, we'd have to start supporting .statement(0xaddr).return
  probes and map them to the appropriate uretprobes.  This part could be
tricky.
