what needs to be done to support gdbserver on netbsd?

[Jeff Rizzo]

Hi-

I'm doing some development under NetBSD on an embedded system, and
am wondering what needs to be added to gdbserver to support a
netbsd target;  all the current platforms seem to be Linux.

I see some mention of NetBSD and gdbserver in some posts to the
list by J.T. Conklin in 2000 and 2001, but nothing since then
that I can see.  

I am, of course, not particularly knowledgeable regarding GDB,
except as a user... but I would love to be able to debug
a remote target...

Thanks!

Someone needs to implement it.  Lots of the code in linux-low.c
probably needs to be abstracted out for the NetBSD code to share. 
Other bits need to be rewritten into a netbsd-low.c and
a netbsd-<arch>-low.c.

Starting with the Linux code as an example, it shouldn't be overly
difficult, but it'll probably take a while.  A lot of the Linux code is
threads-related, so can be dispensed with for a first pass.

I'm afraid I don't know anything about NetBSD...
