(avail_exprs_stack): Similarly. Change type of global from a pair of expr_hash_elt_t to the new class. (expr_elt_hasher::hash): Corresponding changes. (expr_elt_hasher::equal): Similarly. (avail_expr_hash): Similarly. (pass_dominator::execute): Similarly. (dom_opt_dom_walker::thread_across_edge): Similarly. (record_cond): Similarly. (dom_opt_dom_walker::before_dom_children): Similarly. (dom_opt_dom_walker::after_dom_children): Similarly. (lookup_avail_expr): Likewise. (initialize_hash_element): Now a expr_hash_elt constructor. (initialize_hash_element_from_expr): Similarly. (free_expr_hash_elt_contents): Now a dtor for class expr_hash_elt. (free_expr_hash_elt): Call dtor for the element. (remove_local_expressions_from_table): Now the "pop_to_marker" method in the available_exprs_stack class. (avail_expr_stack::record_expr): Method factored out. (print_expr_hash_elt): Now a method in the expr_hash_elt class. Fix formatting. (hashable_expr_equal_p): Fix formatting. Modified: trunk/gcc/ChangeLog trunk/gcc/tree-ssa-dom.c
