+ PR tree-optimization/18009
+ * tree-vectorizer.h (enum dr_alignment_support): New type.
+ (MAX_NUMBER_OF_UNALIGNED_DATA_REFS): Removed.
+ (LOOP_UNALIGNED_DR): replaced with LOOP_VINFO_UNALIGNED_DR and holds a
+ single data_reference (instead of a varray of references).
+ * tree-vectorizer.c (new_loop_vec_info): Likewise.
+ (vect_gen_niters_for_prolog_loop): Likewise.
+ (vect_update_inits_of_drs): Likewise.
+
+ (vect_update_inits_of_drs): Setting of DR_MISALIGNMENT moved to
+ vect_enhance_data_refs_alignment.
+ (vect_do_peeling_for_alignment): Likewise.
+ (vect_enhance_data_refs_alignment): Decide if and by how much to peel;
+ this functionality used to be in vect_analyze_data_refs_alignment.
+ Also update DR_MISALIGNMENT due to peeling; this functionality used to
+ be in vect_update_inits_of_drs and vect_do_peeling_for_alignment).
+ (vect_analyze_data_refs_alignment): Decision on whether and by how much
+ to peel moved to vect_enhance_data_refs_alignment. Call
+ vect_supportable_dr_alignment.
+
+ (vect_compute_data_ref_alignment): Set STMT_VINFO_VECTYPE.
+ (vect_compute_data_refs_alignment): Return bool. Consider return value
+ of vect_compute_data_ref_alignment and return true/false accordingly.
+ (vect_enhance_data_refs_alignment): Consider return value of
+ vect_compute_data_refs_alignment and return true/false accordingly.
+
+ (vect_supportable_dr_alignment): New function.
+ (vectorizable_store): Call vect_supportable_dr_alignment.
+ (vectorizable_load): Call vect_supportable_dr_alignment. Alignment
+ support checks moved from here to vect_supportable_dr_alignment.
+
+ (vect_transform_loop): Avoid 80 columns overflow.
