+This is a preliminary release of GDB and GDBSERVE.NLM for Alpha/Netware.
+
+Building this release is very straightforward. You just need to do the
+following:
+
+ 1) Unpack the release. gunzip < gdb-4.12.3.tar.gz | tar xvf -
+ should do the trick.
+ 2) cd gdb-4.12.3
+ 3) ./configure --target alpha-netware
+ 4) make BISON=yacc [You can use either gcc, or the DEC compiler here].
+
+Building GDBSERVE.NLM:
+
+ 1) cd gdb-4.12.3/gdb/nlm
+ 2) Edit Makefile, and change the value to NWAXPDEV to point at the
+ DEC development kit.
+ 3) make
+
+To debug a program, you need to install GDBSERVE.NLM on your server in
+[SYSTEM] (or, anywhere in your search path). Then, connect your netware
+server to the host with a null modem cable. Start up the app you want to
+debug by doing `gdbserve 0 0 APPNAME APP-ARGS ...'. At this point, the
+server will be stopped inside of GDBSERVE, waiting for debugger commands
+from the serial line. Now, you run GDB on a copy of the app .o file,
+and do a target command to connect to the server. `gdb foo.o', then
+(gdb) target remote /dev/tty00. Note that foo.o should not be the NLM.
+It should be the file that is input to alphanlm or nlmconv.
+
+At this point, GDB should be paused at the first instruction of the program
+(that's probably _Prelude). You can put a breakpoint at main, and then do
+a continue command to debug your program. At that point, normal step/next
+commands, backtrace, etc should work.
+
+Known problems:
+
+Sometimes you will see messages like the following:
+ warning: Hit heuristic-fence-post without finding
+ warning: enclosing function for address 0x1112f1f0
+These can be ignored. They are usually associated with stepping over
+external functions (like printf).
+
+Function calling (ie: print foo(42)) is very slow. A fix for this is in
+the works.
+
+Due to last minute problems with GAS, I was not able to build GDBSERVE.NLM
+with our tools, and I was unable to test code compiled with our tools. This
+should not be a problem, as GDB will quite happily debug programs compiled
+with either GCC, or the DEC tools. For the time being, GDBSERVE will be
+compiled with the DEC tools.
+
+We can't build prelude.o because the DEC dev kit didn't supply libhooks.h.
+For the time being, I have just copied prelude.o from the DEC dev kit into
+the GDB kit.
+
+In case of problems:
+
+If GDB hangs when talking to the target, try turning on remote debugging
+(you can use ^C to wake up GDB if necessary). To do this, just type
+`set remotedebug 1'. This will print out the protocol packets whenever
+GDB and GDBSERVE talk to each other.

+/* i386-nlmstub.c -- NLM debugging stub for the i386.
+
+ This is originally based on an m68k software stub written by Glenn
+ Engel at HP, but has changed quite a bit. It was modified for the
+ i386 by Jim Kingdon, Cygnus Support. It was modified to run under
+ NetWare by Ian Lance Taylor, Cygnus Support.
+
+ This code is intended to produce an NLM (a NetWare Loadable Module)
+ to run under NetWare on an i386 platform. To create the NLM,
+ compile this code into an object file using the NLM SDK on any i386
+ host, and use the nlmconv program (available in the GNU binutils)
+ to transform the resulting object file into an NLM. */

+ * The following gdb commands are supported:

+ * g return the value of the CPU registers hex data or ENN

+ *
+ * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN

+ * c Resume at current address SNN ( signal NN)
