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

out of memory allocating 629864 bytes after a total of 4294632428 bytes
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.
