[Bug breakpoints/15165] New: problems saving dprintf breakpoints


http://sourceware.org/bugzilla/show_bug.cgi?id=15165

             Bug #: 15165
           Summary: problems saving dprintf breakpoints
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: breakpoints
        AssignedTo: unassigned@sourceware.org
        ReportedBy: keiths@redhat.com
    Classification: Unclassified


(gdb) dprintf main,"hello"
Dprintf 1 at 0x4004dc: file comma.cc, line 13.
(gdb) save breakpoints bps
../../gdb/gdb/breakpoint.c:13309: internal-error: unhandled breakpoint type 29
A problem internal to GDB has been detected,
further debugging may prove unreliable.

We need to add a dprintf_print_recreate to "do the right thing."

There are no tests for this in the test suite at all (or the internal error
would have been seen long before now).

As a side note, simply adding bp_dprintf to the if/else chain in
bkpt_print_recreate isn't sufficient. It produces output like:
dprintf main
commands
  printf "hello"
  continue
end

which is invalid input. [dprintf /must/ have a format string argument]
