There is a free simulator available from HP in binary form but not 
source form.  There is also some other stuff available from HP, such as 
environments for booting linux on the simulator, and for running IA-64 
binaries on x86 machines via the simulator.  See

Trimaran is an academic project.  There is also ORC (Open Research 
Compiler) which is based on the open-sourced SGI compiler.  Both are 
interesting places to look for Itanium compiler optimization info.

A good source of general info for Itanium Linux issues is
	http://www.gelato.org
It has more info about the simulators and compilers that are available.
