Log message:
	2004-08-26  Daniel Berlin  <dberlin@dberlin.org>
	
	* Makefile.in (lambda-code.o): New.
	(lambda-trans.o): Ditto.
	(TREE_DATA_REF_H): Ditto.
	(LAMBDA_H): Ditto.
	(lambda-mat.o): Use LAMBDA_H.
	(tree-data-ref.o): Ditto.
	* lambda-code.c: New file.  Lambda code generation algorithm.
	* lambda-trans.c: Ditto. Lambda transformation matrix support.
	* lambda.h: Add lambda loop structures.
	Add lambda loopnest structures.
	Add lambda body vector structure.
	Add lambda linear expression structures.
	Add prototypes for functions in new files.
	* lambda-mat.c: Include tree.h

	Sebastian Pop  <pop@cri.ensmp.fr>
	
	* tree-data-ref.h: Include lambda.h
	(free_dependence_relation): Declared here.
	(free_dependence_relations): Ditto.
	(free_data_refs): Ditto.
	* tree-data-ref.c (free_dependence_relation): New function.
	(free_dependence_relations): Ditto.
	(free_data_refs): Ditot.
	(analyze_all_data_dependences): Free datarefs and dependence_relations.
	(build_classic_dist_vector): Store in the dependence_relations the
	information. Each arc in the dependence_relations graph is labelled
	with the distance and direction vectors.
	(build_classic_dir_vector): Ditto.
	(compute_rw_wr_ww_dependences): Renamed again compute_all_dependences.
	Now computes again the whole dependence graph including read-read
	relations.
	(compute_data_dependences_for_loop): Now dependence_relations contains
	all the data, and thus it doesn't need to initialize the classic_dir
	and classic_dist vectors.
	(analyze_all_data_dependences): Adjusted for using the new interface of
	compute_data_dependences_for_loop.  Remove the statistics dump.
