2005-01-06  Daniel Berlin <dberlin@dberlin.org>

	Fix PR tree-optimization/18792

	* tree-data-ref.c (build_classic_dist_vector): Change first_loop
	to first_loop_depth, and use loop depth instead of loop number.
	(build_classic_dir_vector): Ditto.
	(compute_data_dependences_for_loop): Use depth, not loop number.
	* tree-loop-linear.c (try_interchange_loops): Use loop depth, not loop
	number. Pass in loops, instead of loop numbers.
	(gather_interchange_stats): Ditto.
	(linear_transform_loops): Ditto.
