+ * tree-vectorizer.c (slpeel_tree_peel_loop_to_edge): Peeling scheme
+ changed to suppoer uses-after-loop and to void creating flow paths
+ that shouldn't exist.
+ (slpeel_update_phi_nodes_for_guard): Takes additional two arguments.
+ Modified to fit the new peeling scheme. Avoid quadratic behavior.
+ (slpeel_add_loop_guard): Takes additional argument.
+ (slpeel_verify_cfg_after_peeling): New function.
+ (vect_update_ivs_after_vectorizer): Takes additional argument. Updated
+ documentation. Use 'exit-bb' instead of creating 'new-bb'.
+ (rename_variables_in_bb): Don't update phis for BBs out of loop, to fit
+ the new peeling scheme.
+ (copy_phi_nodes): Function removed. Its functionality moved to
+ update_phis_for_duplicate_loop.
+ (slpeel_update_phis_for_duplicate_loop): Functionality of copy_phi_nodes
+ moved here. Added documentation. Modified to fit the new peeling scheme.
+ (slpeel_make_loop_iterate_ntimes): Setting loop->single_exit not not
+ needed - done in slpeel_tree_peel_loop_to_edge.
+ (slpeel_tree_duplicate_loop_to_edge_cfg): Debug printouts compacted.
+ (vect_do_peeling_for_loop_bound): Add documentation. Call
+ slpeel_verify_cfg_after_peeling. Call vect_update_ivs_after_vectorizer
+ with additional argument.
+ (vect_do_peeling_for_alignment): Call slpeel_verify_cfg_after_peeling.
+

+ (vect_update_niters_after_peeling): Removed. Its functionality was
+ moved to vect_do_peeling_for_alignment.
+ (vect_do_peeling_for_loop_bound): New name for function previously
+ called vect_transform_for_unknown_loop_bound.
+ (vect_transform_loop_bound): Call slpeel_make_loop_iterate_ntimes
+ instead of code that duplicates the same functionality.
+ (vect_do_peeling_for_alignment): Functionality of

+ (vect_transform_loop): Unify call to vect_do_peeling_for_loop_bound -

+ previously called verify_loop_for_duplication. All conditions compacted
+ into one compound condition. Removed debug dumps.
+ (vect_analyze_loop_with_symbolic_num_of_iters): Removed. Some of the
+ functionality moved to vect_can_advance_ivs_p, and some to
+ vect_analyze_loop_form.
+ (vect_can_advance_ivs_p): New function. Contains functionality that was
+ taken out of vect_analyze_loop_with_symbolic_num_of_iters.
+ (slpeel_tree_peel_loop_to_edge): Call slpeel_can_duplicate_loop_p.
+ (vect_analyze_operations): Call vect_can_advance_ivs_p and
+ slpeel_can_duplicate_loop_p.
+ (vect_get_loop_niters): Added documentation.
+ (vect_analyze_loop_form): Check the loop entry always - not only in case
+ of unknown loop bound. Create preheader and exit bb if necessary. Apply
+ a check that used to take place in
+ vect_analyze_loop_with_symbolic_num_of_iters.
+ (vectorize_loops): Call verify_loop_closed_ssa under ENABLE_CHECKING.
+ Remove redundant call to rewrite_into_loop_closed_ssa.
