We're currently working on improving SuperH support in Debian and Linux
in general since the architecture is currently being redeveloped as an
open source architecture called J-Core [1]. J-Core supports the SH-2
instruction set only, but it's expected to extend to SH-3 and SH-4
in the future. Hence, having working native SH support for gdb on Linux
would be very desirable.

This would actually the first and most important thing to do. I have
tried contacting Takashi YOSHII but so far I had no success. One that
could help would be Nobuhiro Iwamatsu, so I put him in CC. There is
also Yutaka Niibe whom we can ask.
