	                 tree.c 

Log message:
	* Makefile.in (tree-ssa-loop-manip.o): Depend on $(SCEV_H)
	instead of tree-scalar-evolution.h.
	* tree-data-ref.c (array_base_name_differ_p): Remove useless
	initialization.
	(tree_fold_bezout): Removed.
	(dump_subscript): New.
	(dump_data_dependence_relation): Use dump_subscript.
	(dump_dist_dir_vectors): New.
	(initialize_data_dependence_relation): Initialize DDR_AFFINE_P.
	(non_affine_dependence_relation): New.
	(analyze_subscript_affine_affine): Use lambda_matrix_right_hermite
	instead of tree_fold_bezout.  Add some more comments.
	(analyze_siv_subscript): Pass to analyze_subscript_affine_affine not
	only univariate dependence relations, but also multivariate ones.
	(analyze_miv_subscript): Same.  Add more comments.
	(undetermined_conflicts_p, no_conflicts_p): New; in use...
	(subscript_dependence_tester): ...here.
	(build_classic_dist_vector, build_classic_dir_vector): Use
	non_affine_dependence_relation for classifying relations that
	cannot be represented as distance vectors.
	(analyze_all_data_dependences): Use dump_dist_dir_vectors.
	Restructure the dumping.
	* tree-data-ref.h (data_dependence_relation): Add a boolean
	field affine_p.
	(DDR_AFFINE_P): And its accessor.
	(dump_subscript, dump_dist_dir_vectors): Declared here.
	* tree-loop-linear.c (linear_transform_loops): Use
	dump_dist_dir_vectors.
	* tree-scalar-evolution.h: Include tree-chrec.h.
	* tree.c (tree_fold_gcd): Use TRUNC_MOD_EXPR for computing the
	modulo operation with C semantics.
