             Bug #: 15349
           Summary: gcore not implemented for AIX
           Product: gdb
           Version: 7.5
            Status: NEW
          Severity: normal
          Priority: P2
         Component: corefiles
        AssignedTo: unassigned@sourceware.org
        ReportedBy: raunaq@outlook.com
    Classification: Unclassified


On running "gcore -o filename PID" I get an error saying - 

Command not implemented for this target.

I also tried attaching the Process while running gdb and using gcore as a sub
command. Still giving the same issue. 

Is it very hard to get gcore working on AIX ?

If you know the format of core files on AIX, then I think it
shouldn't be too hard.

Ok, I know the format of core files on AIX. So basically, what that means is
that the AIX core file structure has a certain fields, I need to populate those
fields by gathering information (about the process being debugged) already
available to gdb and save it as a core file ?

If so, it would be really helpful if you could give me a an idea as to where in
gdb or which structure would save such information about the process being
debugged which would be helpful in filling the fields of the core structure.

The best in these cases really is to just pick a box that supports gcore (like
GNU/Linux), put a break on the gcore command entry point, and step through the
code to see how it's implemented there.
