gdb remote intel host powerpc target no breakpoints

["Christopher R. Johnson" <cjohnson at gcctech dot com>]

HELP!

I have built a host gdb for intel and a target gdbserver for powerpc.  I 
can't get breakpoints to work.  When I set debug remote 1, I see the 
"Z0" message being sent from the host, and the client responds with an 
empty packet.  The host decides that "Packet Z0 (software-breakpoint) is 
NOT supported".  A quick look at the code in gdbserver, and voila! 
There is no code for handling the "draft" "Z" messages used to set and 
clear break/watch points, etc.  The host and client ARE talking, so 
there's at least that much to celebrate.

On the host side I see some interesting code in gdb/remote.c under 
#ifdef DEPRECATED_REMOTE_BREAKPOINT that looks like it COULD do 
something more reasonable (how do I turn this on in the build?)

Unless I'm missing something fundamental (quite likely) one of the 
following must be true:

1. There is no breakpoint support in gdbserver to match the "draft" Z 
packet standard.
2. There is no support on the host side to adapt to "deprecated" 
breakpoint methods to allow gdbserver compatibility.
3. There is support on the host side and I just don't know how to find 
it or build for it.

I'm hoping #3 is correct, and someone out there can tell me the magic 
for building gdb properly for my situation.  Otherwise, anyone with 
remote gdb working cross-platform, please advise!  Any clues would be 
greatly appreciated!  Suppliers of useful information in the Eastern 
Mass. area get a free beer!
