I'd love to see an Itanium port, but I don't think it's realistic in 
view of the limited number of manufacturers shipping systems based on it 
and the known difficulty of filling the bundles. I haven't had a chance 
of looking at GCC output to see how well their backend does, but the 
last I heard it was difficult to get even 75% utilisation. Add to that 
the the opcode set etc. is weird: SPARC-style register windows with none 
of the charm.

To my surprise I've got an Alpha system, but my understanding is that 
nobody's making silicon any more. Since Chinese manufacturers appear to 
have settled on MIPS as their non-x86 of choice, I don't see much future 
for it.

Vis, LLVM, and- of course- the Android and JVM ports are obviously 
valuable. Apart from that the only architecture that FPC doesn't support 
is the IBM S/390.
