[Bug symtab/12406] New: Send a more detailed notification on solib events.

           Summary: Send a more detailed notification on solib events.
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab
        AssignedTo: unassigned@sourceware.org
        ReportedBy: andre.poenitz@nokia.com


Right now the message is rather simple "something happened". It would be nice
if it could e.g. say which shared object triggered the event.

Is this for MI or the CLI?

For MI, I think you are supposed to look at the
=library-loaded and =library-unloaded async notifications.

--- Comment #2 from Andre Poenitz <andre.poenitz at nokia dot com> 2011-01-25 07:08:36 UTC ---

In this particular case it was the non-MI version.

However, I think also the MI version could be a bit more verbose. There is e.g.
(even with auto-solib-add on):

>=library-loaded,id=".../lib/libQtNetworkMyns.so.4",target-name=".../lib/libQtNetworkMyns.so.4",host-name=".../lib/libQtNetworkMyns.so.4",symbols-loaded="0"

Naively, I would have expected symbols-loaded="1", and perhaps the 'From' and
'To' address values that are displayed with 'info shared'.

Somewhat hacky fix for the CLI side.
