	gcc            : ChangeLog.lno optabs.c optabs.h 
	                 tree-vectorizer.c tree-vectorizer.h 

Log message:
	* tree-vectorizer.h (struct _loop_vec_info): Field num_iters is now
	HOST_WIDE_INT.
	* tree-vectorizer.c (vect_get_loop_niters): Takes HOST_WIDE_INT instead
	of int as argument.
	(vect_analyze_loop_form): number_of_iterations is now HOST_WIDE_INT.
	
	(vect_transform_load, vect_is_supportable_load): Replaced with
	vectorizable_load.
	(vect_tranrform_store, vect_is_supportable_store): Replaced with
	vectorizable_store.
	(vect_transform_op, vect_is_supportable_op): Replaced with
	vectorizable_operation.
	(vect_transform_assignment, vect_is_supportable_assignment): Replaced
	with vectorizable_assignment.
	(vectorizable_load, vectorizable_store, vectorizable_operation):
	(vectorizable_assignment): New functions.
	(vect_analyze_operations): Use above new functions.
	
	(vect_get_array_first_index): Replaced by vect_get_first_index.
	(vect_get_first_index): New Function.
	
	(vect_force_dr_alignment_p): Replaced with
	vect_can_force_dr_alignment_p.
	(vect_can_force_dr_alignment_p): New function.
	(vect_get_base_decl_and_bit_offset): New function.
	(vect_compute_array_alignment): Take trees instead of ints as arguments.
	Return tree (the array base) rather than bool.
	(vect_align_data_ref): Functionality moved to
	vect_analyze_data_ref_alignment.
	(vect_compute_data_ref_alignment): Use above new function. Perform
	arithmetic on trees rather than ints.
	
	(vect_get_vec_def_for_operand): Test for IS_EMPTY_STMT.
	(vect_is_simple_use): Test for IS_EMPTY_STMT.
	
	(tree_nargs): Removed.
	(vect_get_new_vect_var): Use concat and avoid unnecessary malloc.
	(vect_create_index_for_array_ref): Remove check of step.
	(vect_create_data_ref): vect_ptr is pointer to array of vectype (rather
	than pointer to vectype). Use build_fold_addr_expr. Avoid using
	force_gimple.
	(vect_create_destinamtion_var): Remove ALIAS_SET setting.
	(vect_transform_loop_bound): Use fold_convert to assign a type to
	new_loop_bound.
	(vect_analyze_pointer_ref_access): Use host_integerp.
	(vect_analyze_data_refs): Change handling of COMPONENT_REF case; call
	vect_get_base_decl_and_bit_offset.
	(ANALYZE_ALL_THEN_VECTORIZE_ALL): "#ifdef" removed.
	
	* optabs.c (optab_for_tree_code): Bring from mainline.
	* optabs.h (optab_for_tree_code): Bring from mainline.
