Just noticed weird state of it. One reason you don't own it is that it essentially doesn't exist. :-) GCC dropped SH64 support a few years ago because the arch essentially never materialized and keeping it around was a lot of cruft. It should be removed from the kernel too; I just haven't gotten around to figuring out how to do that. Rich
