             Bug #: 14311
           Summary: always report alternatives & positions in probe point
                    error messages
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
        AssignedTo: systemtap@sourceware.org
        ReportedBy: smakarov@redhat.com
    Classification: Unclassified


When implementing alias suffixes, it was necessary to slightly simplify the
error reporting on probe mismatch. The following currently missing information
that might be more comprehensively reported in the future:

- The position number of the mismatched component within the probe is no longer
given. (it might not be necessary to add this back now, since the exact same
information is expressed by showing the source coordinates of the mismatch
error)

- In complex situations involving both alias suffixes, the full set of
available suffixes might not be reported when there is a mismatch error.
Collecting this information accurately probably requires a much more involved
error handling scheme than what is currently used.
