A funny thing is that I wrote all the important bits of Attunity's RMS CDC,
which has to wedge into RMS and system service dispatching, in Macro-32 for
both Alpha and Itanium. ;)  If you know what you're doing, it can be done.  
The Itanium instruction formats, thankfully, are well documented and there
are macros defining them ($IPFINSDEF).  It would've been easier if address
bits in a bundle weren't chopped up and tossed about to land like confetti.
