From 4721cf1ecb949b37c98b6fce79163541711de2e5 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Thu, 3 Dec 1998 23:54:14 +0000 Subject: Patch from Emmanuel Raguet to add remote debug server 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. --- c/src/librpc/src/xdr_mem.c | 185 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 185 insertions(+) create mode 100644 c/src/librpc/src/xdr_mem.c (limited to 'c/src/librpc/src/xdr_mem.c') diff --git a/c/src/librpc/src/xdr_mem.c b/c/src/librpc/src/xdr_mem.c new file mode 100644 index 0000000000..280451a349 --- /dev/null +++ b/c/src/librpc/src/xdr_mem.c @@ -0,0 +1,185 @@ +/* @(#)xdr_mem.c 2.1 88/07/29 4.0 RPCSRC */ +/* + * Sun RPC is a product of Sun Microsystems, Inc. and is provided for + * unrestricted use provided that this legend is included on all tape + * media and as a part of the software program in whole or part.
