Over the past few months I've been working on GDB's SPARC target.
Adapting the SPARC-specific parts of GDB to the internal changes that
have been made recently made me effectively do a rewrite of those
parts.  In addition to the generic SPARC support, the new code
includes support for the following operating systems:

* Solaris (32-bit and 64-bit)
* GNU Linux (32-bit and 64-bit)
* FreeBSD/sparc64
* NetBSD/sparc
* NetBSD/sparc64

The testing I've done myself, and the feedback I've had from a few
users seems to indicate that the new code is much better than what's
in GDB 6.0, and that there are significant improvements relative to
GDB 5.3.  However, I haven't been able to test NetBSD/sparc64.
Therefore, I'd really appreciate it if someone with access to a
NetBSD/sparc64 could test the new code.  The code lives on a branch named

   kettenis_sparc-20030918-branch

of the CVS repository on sourceware.redhat.com.  See

   http://sources.redhat.com/gdb/

for more information about checking out the code.

Thanks,

Mark Kettenis
