New Revision: 125642

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=125642
Log:
	* tree-vectorizer.h (vect_def_type): Start enumeration from 1.
	(_slp_tree, _slp_instance): New structs along with macros for fields'
	access.
	(_loop_vec_info): Add new fields strided_stores, slp_instances and
	slp_unrolling_factor with access macros.
	(enum slp_vect_type): New.
	(_stmt_vec_info): New field slp_type and macro to access it.
	* tree-vectorizer.c (new_stmt_vec_info): Initialize the new fields.
	(new_loop_vec_info): Likewise.
	(destroy_loop_vec_info): Free the new fields.
	* tree-vect-analyze.c (vect_analyze_operations): Call vectorizable_
	functions with correct arguments. For not pure SLP stmts with strided
	access check that the group size is power of 2. In case that the loop
	can be SLPed purely update the vectorization factor.
	(vect_analyze_data_ref_access): Don't fail for not power of 2 group
	size. If possible to SLP the group, store it for future analysis.
	(vect_get_and_check_slp_defs, vect_build_slp_tree, vect_free_slp_tree,
	vect_print_slp_tree, vect_mark_slp_stmts, vect_analyze_slp_instance,
	vect_analyze_slp, vect_make_slp_decision, vect_detect_hybrid_slp_stmts,
	vect_detect_hybrid_slp): New.
	(vect_analyze_loop): Call vect_analyze_slp, vect_make_slp_decision and
	vect_detect_hybrid_slp.
	* tree-vect-transform.c (vect_get_constant_vectors, 
	vect_get_slp_vect_defs, vect_get_slp_defs): New.
	(vectorizable_reduction): Fail if SLP.
	(vectorizable_call, vectorizable_induction, vectorizable_type_demotion,
	vectorizable_condition): Likewise.
	(vectorizable_conversion): Handle SLP (call vect_get_slp_defs to get
	SLPed defs).
	(vectorizable_assignment, vectorizable_operation, vectorizable_store,
	vectorizable_load): Likewise.
	(vect_transform_stmt): Pass SLP arguments if supported and assert no
	SLP for unsupported cases.
	(vect_remove_stores, vect_schedule_slp_instance, vect_schedule_slp):
	New.
	(vect_transform_loop): Call vect_schedule_slp.
