I was currious if anyone else interested-in/working-on a gdb stub for ia64?

I've been modifying the i386 version of a kdb to gdb stub, skdb, to work
on the ia64, and was thinking of playing around this weekend a bit and
sorting out register assignment problems. I just thought I'd see if anyone
else was interested-in or working-on this or a direct ia64_stub.c for gdb
for the public domain.

Seems strange that a google search still only shows myself when I search on the
{ia64 gdb stub} keywords. I'd just like double check and avoid duplicating effort.

HP has an exceptional version of GDB, KWDB, that can do src debugging
over the internet and it appears to have been ported to ia64. Unfortunately,
the stub doesn't appear to be under the GNU copyleft.

Standard gdb can do this.  It is called gdbserver, and it has been a part of
gdb since 1993.

Before we had hardware, initial gdb work was done by running gdbserver under
linux on the simulator, and then connecting to it via tcp/ip from a cross-gdb
running on an x86-linux machine.  This was much faster than trying to run an
interactive gdb session under linux on the simulator.

The IA-64 gdbserver support is still there, but I don't know if anyone has
used it since we got hardware.  See the src/gdb/gdbserver directory in the
FSF GDB source tree.
