that addresses the librdbg/rpcgen related problems:
Changes:
* All rpcgen generated files are now kept inside of the source tree
* Fix librdbg/configure to correctly detect presence of rpcgen and awk
* Use rpcgen -m to generated remdeb_svc.c
* Remove msgout/_msgout from awk.svc
* minor cleanups to librdbg/configure.in
ATTENTION --- IMPORTANT:
* With keeping rpc-generated files pre-build inside of the source tree,
you as the packager of RTEMS have to ensure that timestamps are
correctly set up: The generated files must not be older than the *.x
files.
* This is extraordinarily important when
- putting the package on read-only media
- after checking out from CVS
- after modifications to the *.x files
* If one of the *.x files is modified you have to either
- build for i386/pc386 and powerpc/mcp750
- or to invoke the same rpcgen calls as the
librdbg/src/<cpu>/<bsp>/Makefile.am do manually
before checking-in the files to CVS.
Proposal:
We could add something to bootstrap for touching the rpcgen-generated
sources and/or to manually regenerate them.
NOTE FROM JOEL:
Ralf proposed modifying bootstrap to handle rpcgen. I think this
is the best solution as it is something already done in the
snapshot procedure.

<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),

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.
