re PR tree-optimization/18009 (ICE in vect_transform_stmt, at tree-vectorizer.c:2625 (testcase included))
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. From-SVN: r90051
