Browse source 
2004-12-15  Daniel Berlin  <dberlin@dberlin.org>

	* cfgloop.c (flow_loops_dump): Don't print out levels.
	(flow_loops_find): Don't set loop->levels.
	(flow_loops_level_compute): Make void.
	* cfgloop.h (struct loops): Remove levels member.
	Add comment about loops in parray possibly being NULL.
