This is a question received by Intel Software Network Support, followed by the response received from our engineering contacts:
Q. I read about IA-64 Assembly Assistant in the Intel Technology Journal article Assembly Language Programming Tools for the IA-64 Architecture, but was unfortunately unable to find it. It looks like a nice educational tool. Is it not available anymore?
A. The Intel Technology Journal article linked above was written in 1999. Unfortunately, this tool is no longer available. To do what it did, the tool needed to know details about the specific implementation (latencies, number and types of execution units, etc.). It was not updated for the differences between IntelItanium processors and the more recent Intel Itanium 2 processors, and as a result is no longer distributed.
It was an awesome tool though.
