2005-11-19  Paolo Bonzini  <bonzini@gcc.gnu.org>

	* gensupport.c (old_preds): Rename to std_preds, add special field.
	(struct old_pred_table): Rename to struct std_pred_table, add special
	field.
	(NUM_KNOWN_OLD_PREDS): Rename to NUM_KNOWN_STD_PREDS.
	(NUM_OLD_SPECIAL_MODE_PREDS): Remove.
	(init_predicate_table): Adjust, and set along the way whether a
	predicate is special.
