tree-ssa-sccvn.h (struct vn_phi_s): Make phiargs member a trailing array.
2018-07-19 Richard Biener <rguenther@suse.de>
* tree-ssa-sccvn.h (struct vn_phi_s): Make phiargs member
a trailing array.
* tree-ssa-sccvn.c: Remove alloc-pool.h use.
(vn_phi_hasher): Derive from nofree_ptr_hash and remove remove method.
(vn_reference_hasher): Likewise.
(struct vn_tables_s): Remove obstack and alloc-pool members.
(vn_tables_obstack, vn_tables_insert_obstack): New global obstacks.
(vn_nary_build_or_lookup_1): Manually build in vn_tables_insert_obstack.
(vn_reference_insert): Allocate from obstack instead of from alloc-pool.
(vn_reference_insert_pieces): Likewise.
(alloc_vn_nary_op_noinit): Adjust.
(vn_nary_op_insert_stmt): Allocate phiargs in-place.
(vn_phi_eq): Adjust.
(shared_lookup_phiargs): Remove.
(vn_phi_lookup): Allocate temporary vn_phi_s on the stack.
(vn_phi_insert): Allocate from obstack instead of from alloc-pool.
(visit_reference_op_call): Likewise.
(copy_nary, copy_phi, copy_reference): Remove.
(process_scc): Rewind the obstack when iterating. Do not
copy the elements to valid_info but just move them from one
hashtable to the other.
(allocate_vn_table): Adjust.
(free_vn_table): Likewise.
(init_scc_vn): Likewise.
(free_scc_vn): Likewise.
