tree-vectorizer.h (unknown_alignment_for_access_p): Replaced by known_alignment_for_access_p.
* tree-vectorizer.h (unknown_alignment_for_access_p): Replaced by
known_alignment_for_access_p.
(known_alignment_for_access_p): New.
(do_peeling_for_alignment): Field made int instead of bool and renamed
to peeling_for_alignment.
(LOOP_DO_PEELING_FOR_ALIGNMENT): Renamed to LOOP_PEELING_FOR_ALIGNMENT.
* tree-vect-analyze.c (vect_determine_vectorization_factor): New. This
functionality used to be in vect_analyze_operations.
(vect_analyze_operations): Code to determine vectorization factor was
moved to vect_determine_vectorization_factor.
(vect_enhance_data_refs_alignment): Update to correct alignment when it
is known instead of -1. Set LOOP_PEELING_FOR_ALIGNMENT to peeling
factor.
(vect_analyze_loop): Call vect_determine_vectorization_factor (used to
be part of vect_analyze_operations).
* tree-vectorizer.c (slpeel_tree_peel_loop_to_edge): Use fold when
creating the guard condition, as the number of iterations may be
constant.
(slpeel_tree_peel_loop_to_edge): Use new name of
LOOP_DO_PEELING_FOR_ALIGNMENT. Set it to 0 instead of false.
* tree-vect-transform.c (vect_gen_niters_for_prolog_loop): Handle known
alignment case more efficiently. Use LOOP_PEELING_FOR_ALIGNMENT.
(vect_do_peeling_for_alignment): Use fold.
(vect_transform_loop): Use new name of LOOP_DO_PEELING_FOR_ALIGNMENT.
(vect_update_inits_of_dr): Renamed to
vect_update_init_of_dr.
(vect_update_inits_of_drs): Use new name of vect_update_inits_of_dr.
(vectorizable_store): Fix assertion to use == instead of =.
