Not sure on what you mean.  The same GEM code generator for Alpha is the one 
we use for Itanium.  You get all the optimizations you get on Alpha.  Does 
it take full advantage of all the Itanium additional features, no it does 
not.  But you get all the loop optimization, routine inlining, dataflow 
analysis, etc. that you get on Alpha.

The code generater used by the HP-UX side is pretty darned good as well as 
the Intel code generator.  Both know how to use the various data and control 
speculation on the chip.  Have you looked at them at all?
