With the branch prediction, cache tracing, and EPIC instructions,
you really want to use an ILP compiler. Without a compiler that
can decide on good ways to output binaries that run with all the IA-64

I will reserve my opinions on whether Intel will succeed in
implementing the EPIC stuff well. ;-)
IIRC, KA-64 does not even have an emulator yet. Rest assured that
there will be a lot of people in and out of this project interested
in supporting a KA-64 port of FreeBSD.

When Sledgehammer comes out, we will see what we can do. :)
