From b9c257340bd20ec0e7debffc62ed3e3901c2908d Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Wed, 20 Dec 2017 12:52:58 +0000 Subject: poly_int: ao_ref and vn_reference_op_t This patch changes the offset, size and max_size fields of ao_ref from HOST_WIDE_INT to poly_int64 and propagates the change through the code that references it. This includes changing the off field of vn_reference_op_struct in the same way. 2017-12-20 Richard Sandiford Alan Hayward David Sherwood gcc/ * inchash.h (inchash::hash::add_poly_int): New function. * tree-ssa-alias.h (ao_ref::offset, ao_ref::size, ao_ref::max_size): Use poly_int64 rather than HOST_WIDE_INT. (ao_ref::max_size_known_p): New function. * tree-ssa-sccvn.h (vn_reference_op_struct::off): Use poly_int64_pod rather than HOST_WIDE_INT. * tree-ssa-alias.c (ao_ref_base): Apply get_ref_base_and_extent to temporaries until its interface is adjusted to match. (ao_ref_init_from_ptr_and_size): Handle polynomial offsets and sizes. (aliasing_component_refs_p, decl_refs_may_alias_p) (indirect_ref_may_alias_decl_p, indirect_refs_may_alias_p): Take the offsets and max_sizes as poly_int64s instead of HOST_WIDE_INTs. (refs_may_alias_p_1, stmt_kills_ref_p): Adjust for changes to ao_ref fields. * alias.c (ao_ref_from_mem): Likewise. * tree-ssa-dce.c (mark_aliased_reaching_defs_necessary_1): Likewise. * tree-ssa-dse.c (valid_ao_ref_for_dse, normalize_ref) (clear_bytes_written_by, setup_live_bytes_from_ref, compute_trims) (maybe_trim_complex_store, maybe_trim_constructor_store) (live_bytes_read, dse_classify_store): Likewise. * tree-ssa-sccvn.c (vn_reference_compute_hash, vn_reference_eq): (copy_reference_ops_from_ref, ao_ref_init_from_vn_reference) (fully_constant_vn_reference_p, valueize_refs_1): Likewise. (vn_reference_lookup_3): Likewise. * tree-ssa-uninit.c (warn_uninitialized_vars): Likewise.
