Edmar,

	The e500mc support pushes genautomata over the 256MB data mark,
which requires special flags on AIX.  I have a patch for the GCC build to
work around that.

	The retire automaton was removed from the description for divide,
but it still is a long delay after simple FPU operations, making it very
large.  I would like to remove the long retire stage from the other float
operations.  Downstream tools distributors for embedded customers can add
it back when appropriate.

David
