Hi,
I would like to add a new target to GDB, and then use the following command,
configure --target=arc-elf
However, only got message,
...
check for X... libraries, headers
configure: error: "*** GDB does not support target arc-unknonw-elf"
make[1]: *** [configure-gdb] Error 1
...
I suppose ARC has already been supported by BFD, so I have followed
instructions here
http://sources.redhat.com/gdb/current/onlinedocs/gdbint_9.html#SEC83
In addtion, I have modified gdb/Makefile.in to add rule for
arc-tdep.o. are there other things missing?

Pick some other target, and search for places it is handled. The next
that I can think of is gdb/configure.tgt.

Hi,
Which ARC do you want to run gdb for ? The ARC gdb is not supported in
the mainline sources yet . Maybe you want to look at
http://arc-linux.org for more info.
cheers

P.S. Sorry about the commercial for others reading this.

Some of the steps you will need to do:
* add entries to gdb/configure.tgt for your arc-elf target.
* implement a source module gdb/arc-tdep.c
* add rule for arc-tdep.o to Makefile.in
* add configure directory gdb/config/arc.
Ah, wait -- I see that it's already there, but it's empty.
* In the configure directory, you may add bits such as a
target makefile fragment (eg. "arc.mt"), which will be
added to the Makefile at configure time
When I need to add a new target, I usually pick an existing target
to look toward as an example. Of course it helps to pick an example
that is similar to your target. If your target is native linux, for
instance, you might pick sparc64-*-linux to investigate / emulate.
OTOH, if you're doing a simple embedded target, or maybe a bare-bones
simulator, you might pick eg. the d10v or m32r.

That would be:
2002-08-06 Andrew Cagney <cagney@redhat.com>
* configure.tgt: Make arc-*-* obsolete.
* NEWS: Mention that arc-*-* has been identifed as obsolete.
* MAINTAINERS: Make arc-elf obsolete.
* arc-tdep.c: Make file obsolete.
* config/arc/arc.mt: Ditto.
* config/arc/tm-arc.h: Ditto.
(I do not recommend anyone working with arc use the old port as a base;
it's worth redoing from scratch, since it stood still while GDB
changed).
