It isn't in the main gcc tree but given that Altera has GNU tools 
(nios-elf) which include a simulator,
it looks like a very doable port.  The exception/interrupt model appears 
quite straightforward.

Simple answer is that my 10 minute analysis says that if you aimed at a 
port to the simulator
(and it supported some clock interrupt source), it would be on the 
easier side of the port
effort scale.

Nice name. :)
