I am currently trying to modify GHC 6.6.1 to run on Itanium in multithreaded mode (+RTS -N). Is it possible to do those modifications without generating back-end for Itanium? (If I am correct GHC on Itanium uses gcc to generate the code)

It should be possible, all you have to do is implement the primitives in includes/SMP.h for Itanium (IIRC someone else asked about this recently but I can't find the message, you might want to check the archives). Cheers, Simon
