[PATCH][GCC] Make DR_TARGET_ALIGNMENT compile time variable
This patch enables targets to describe DR_TARGET_ALIGNMENT as a compile-time
variable. It does so by turning the variable into a 'poly_uint64'.
gcc/ChangeLog:
2018-11-13 Andre Vieira <andre.simoesdiasvieira@arm.com>
* config/aarch64/aarch64.c
(aarch64_vectorize_preferred_vector_alignment): Change return type to
poly_uint64.
(aarch64_simd_vector_alignment_reachable): Adapt to preferred vector
alignment being a poly int.
* doc/tm.texi (TARGET_VECTORIZE_PREFERRED_VECTOR_ALIGNMENT): Change
return type to poly_uint64.
* target.def (default_preferred_vector_alignment): Likewise.
* targhooks.c (default_preferred_vector_alignment): Likewise.
* targhooks.h (default_preferred_vector_alignment): Likewise.
* tree-vect-data-refs.c (vect_calculate_target_alignment): Likewise.
(vect_compute_data_ref_alignment): Adapt to vector alignment being a
poly int.
(vect_update_misalignment_for_peel): Likewise.
(vect_enhance_data_refs_alignment): Likewise.
(vect_find_same_alignment_drs): Likewise.
(vect_duplicate_ssa_name_ptr_info): Likewise.
(vect_setup_realignment): Likewise.
(vect_can_force_dr_alignment_p): Change alignment parameter type to
poly_uint64.
* tree-vect-loop-manip.c (get_misalign_in_elems): Learn to construct a
mask with a compile time variable vector alignment.
(vect_gen_prolog_loop_niters): Adapt to vector alignment being a poly
int.
(vect_do_peeling): Exit early if vector alignment is not constant.
* tree-vect-stmts.c (ensure_base_align): Adapt to vector alignment being
a poly int.
(vectorizable_store): Likewise.
(vectorizable_load): Likweise.
* tree-vectorizer.h (struct dr_vec_info): Make target_alignment field a
poly_uint64.
(vect_known_alignment_in_bytes): Adapt to vector alignment being a
poly int.
(vect_can_force_dr_alignment_p): Change alignment parameter type to
poly_uint64.
