	* tree-vectorizer.h (struct _loop_vec_info): Add num_iters_unchanged
	field.
	(LOOP_VINFO_NITERS_UNCHANGED): Define to num_iters_unchanged field.
	* tree-vectorizer.c (set_prologue_iterations,

Harsha Jagasia 749cc4b1b3 tree-vectorizer.c (slpeel_add_loop_guard): Gimplify the condition.
2007-12-05  Harsha Jagasia <harsha.jagasia@amd.com>

	* tree-vectorizer.c (slpeel_add_loop_guard): Gimplify the condition.
	(set_prologue_iterations): New. Set the prologue iterations to total
	number of scalar iterations if the cost model check indicates that
	scalar code should be generated.
	(slpeel_tree_peel_loop_to_edge): Add a new parameter and code for 
	generating the cost condition for epilog. Call
	set_prologue_iterations to generate cost condition for prolog.
	(new_loop_vec_info): Initialize LOOP_VINFO_NITERS_UNCHANGED.
	* tree-vectorizer.h (LOOP_VINFO_NITERS_UNCHANGED): New.
	(slpeel_tree_peel_loop_to_edge): Update declaration.
	(set_prologue_iterations): New declaration.
	* tree-vect-analyze.c (vect_analyze_loop_form): Update 
	LOOP_VINFO_NITERS_UNCHANGED.
	* tree-vect-transform.c
	(vect_estimate_min_profitable_iters): Add new parameter and
	code to  check if run time cost model test is needed.
	Remove code that adds builtin vectorization cost to scalar
	outside cost for the run time cost model test. If run time
	cost model test is needed add the appropriate guard cost to
	the scalar outside cost. The guard cost depends on whether
	the guard is generated at versioning or at prolog generation
	or at epilog generation. Change cost model equation to include
	scalar outside cost.
	(conservative_cost_threshold): New. Return the less conservative
	profitability threshold between the cost model threshold and the
	user defined vectorization threshold.
	(vect_do_peeling_for_loop_bound): Call conservative_cost_threshold.
	(vect_do_peeling_for_alignment): Same.
	(vect_loop_versioning): Same.
	(vect_create_cond_for_align_checks): ANDs the cost model condition
	with the alignment condition.
	(vect_transform_loop): Call loop versioning only when there is a
	misalignment or an aliasing problem.

        * tree-vect-transform.c (vect_align_data_ref): Removed.
        (vect_create_data_ref_ptr): Added additional argument - ptr_incr.
        Updated function documentation. Return the increment stmt in ptr_incr.
        (bump_vector_ptr): New function.
        (vect_get_vec_def_for_stmt_copy): New function.
        (vect_finish_stmt_generation): Create a stmt_info to newly created
        vector stmts.
        (vect_setup_realignment): Call vect_create_data_ref_ptr with additional
        argument.
        (vectorizable_reduction, vectorizable_assignment): Not supported yet if
        VF is greater than the number of elements that can fit in one vector
        word.
        (vectorizable_operation, vectorizable_condition): Likewise.
        (vectorizable_store, vectorizable_load): Support the case that the VF
        is greater than the number of elements that can fit in one vector word.
        (vect_transform_loop): Don't fail in case of multiple data-types.
        * tree-vect-analyze.c (vect_determine_vectorization_factor): Don't fail
        in case of multiple data-types; the smallest type determines the VF.
        (vect_analyze_data_ref_dependence): Don't record datarefs as same_align
        if they are of different sizes.
        (vect_update_misalignment_for_peel): Compare misalignments in terms of
        number of elements rather than number of bytes.
        (vect_enhance_data_refs_alignment): Fix/Add dump printouts.
        (vect_can_advance_ivs_p): Fix a dump printout
