There is Itanium microarchitecture documentation available from Intel, and there is general DFA documentation available in the gcc docs. However, there is no documentation specifically for the itanium dfa descriptions. You just have to spend a lot of time looking at them, and eventually they start to make sense. By the way, I didn't write them, and fortunately haven't had to modify them yet. Hopefully I never will. -- Jim Wilson, GNU Tools Support, http://www.specifix.com
