We started this thread about Samba on Itanium hence my discussion of
byte/word instructions.
For pre EV56 systems, yep you'll need to deal with only long/quad
instructions. Which was the main reason for the /GRANULARITY qualifier on
those Alpha compilers. For Itanium, we kept the /GRANULARITY qualifier to
be compatible with Alpha, but you always get byte granularity since we can
provide that without any extra overhead.
