	My problem is not creating the NDFA description.  I have one DFA
description for just the function units and a second description adding
the dispatch groups.  The function unit description produces a fairly
compact automata.  The more complete description of the dispatch groups
either crashes genattrtab with

Prepare automaton `power4' creation...done

on a small memory machines, or if I expand the memory limit on an AIX
system with 64GB of memory, genattrtab produces screenfuls of '*' but does
not produce an automata in the hour I let it run.  I tried both with and
without

(automata_option "ndfa")

	Describing the pipeline is not useful if the automata generator
cannot produce a scheduler.
