because we were unable to find correct solution to compile on various
linux distros (due to rpcgen incompatibilities), and because the coding
style of rdbg was rather inconsistant among various pieces of code, I
decided to:
1) make some cleaning regarding global coding style (using
indent + manual edits),
2) incorporate/review the paches send by various people
(S. Holford, T. Strauman),
3) Fix the bug due to varying rpcgen code generation
in remdeb_svc.c,
4) Remove some dead code,
5) Apply a patches enabling to call enterRdbg imediately
after rdbg initialization is done,
NB : the paches is huge but it is mainly due to coding styke chnages.
Only few lines of codes have been really changed and they do not impact
rdbg functionnality (AFAIKT).

<raguet@crf.canon.fr>:
- the dec21140 driver code has been hardened (various bug fixed) Emmanuel,
- bug in the mcp750 init code have been fixed (interrupt stack/initial
stack initialization), BSS correctly cleared (Eric V)
- remote debugging over TCP/IP is nearly complete (berakpoints,
backtrace, variables,...) (Eric V),
- exception handling code has also been improved in order to fully
support RDBG requirements (Eric V),

This is an attempt to work-around a couple of nasty bugs in librdbg's
Makefiles and configuration:
Configure and build RTEMS as below:
configure --enable-networking --enable-rdbg --target=i386-rtems
make RTEMS_BSP=i386ex
After a few minutes you will notice that building aborts in librdbg ....
Analysis:
1) librdbg is tried to be built, though librdbg is not supported and the
required directory hierarchy librdbg/i386/i386ex/ is not existant.
The cause for this is incorrect setting of HAS_RDBG in most
make/custom/*.cfg files (except pc386.cfg). At the moment all
custom/*.cfg files (except pc386.cfg) in general are required to contain
HAS_RDBG=no. However, having HAS_NETWORKING=no in most custom/*.cfg
files and the toplevel configure script suppress building librdbg for
all CPUs except of i386.
=> The i386ex BSP falls though this scheme and librdbg is tried to be
build (CPU=i386 and HAS_NETWORKING=yes).
2) The Makefile.ins below lib/librdbg in general support i386/pc386 only
and are not capable to be used for multiple CPUs or BSPs (RPCGEN
generates it's target and bsp-specific files into librdbg/, therefore no
other CPU or BSP can ever be built afterwards). This problem is hidden
until now, because only a single CPU/BSP pair (i386/pc386) is really
supported.
3) The Makefile.ins below lib/librdbg can delete source files due to
improper handling of source files (make clean removes the *.x files in
the source-tree when configuring inside of the source-tree).
The patch below tries to work-around these problems for the i386ex and
the pc386 BSPs. This work-around is rather fragile (it applies rpcgen
-D, I don't know how portable this is) and incomplete (all custom/*.cfg
except of pc386.cfg should contain HAS_RDBG=no), nevertheless it should
work.

and RPC support to RTEMS. Thanks. :) Email follows:
Hello,
For Xmas, here is the Remote Debugger on RTEMS !
Here are 2 patches for the Remote Debugger on RTEMS for pc386 from Linux
host :
- one for RTEMS it self,
- one for GDB-4.17.
1/ RTEMS patch
--------------
This patch adds 2 libraries :
- a simplified SUN RPC library
- the Remote Debugger library
The configuration command is the following :
../rtems4/configure --target=i386-rtemself --enable-rtemsbsp=pc386
--enable-rdbg
The SUN RPC library is built only if networking is set.
The RDBG library is built if networking and enable-rdbg are set.
The function used to initialize the debugger is :
rtems_rdbg_initialize ();
A special function has been created to force a task to be
in a "debug" state : enterRdbg().
The use of this function is not mandatory.
2/ GDB-4.17 patch
-----------------
This patch create a new RTEMS target for GDB-4.17.
The configuration command is the following :
./configure --enable-shared --target=i386RTEMS
To connect to a target, use :
target rtems [your_site_address]
Then, attach the target using : attach 1
And... Debug ;)
You can obtain the original GDB-4.17 on
ftp://ftp.debian.org/debian/dists/stable/main/source/devel/gdb_4.17.orig.tar.gz
This has been tested from a Debian 2.0.1 linux host.
