Would be an interesting task to get NetBSD make use of it.

Which real VAXen have support for it?

None, as far as I know. It was defined in VARM, but never implemented. (But I might be wrong.)
Which doesn't matter so much; we could always add those insn's to simh and do the port. Look at amd64, the emulator was available a long time before the real hardware :-)

...which also calls for extending the vax to 64 bits.  Any takers? :-)
