1111 * pt.c (canonical_template_parms): Correct typo in comment.
1113 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
1115 * typeck.c (structural_comptypes): Renamed from "comptypes".
1116 (comptypes): Use canonical type information to perform fast type
1117 comparison. When VERIFY_CANONICAL_TYPES, verify that the
1118 canonical type comparison returns the same results as we would see
1119 from the current, structural check. Support COMPARE_STRUCTURAL
1120 when we need structural checks.
1121 * decl.c (typename_compare): Fix comment.
1122 (build_typename_type): TYPENAME_TYPE nodes require structural
1123 equality checks, because they resolve different based on the
1125 (make_unbound_class_template): UNBOUND_CLASS_TEMPLATE nodes
1126 require structural equality checks (for now).
1127 (build_ptrmemfunc_type): Build the canonical pointer to member
1129 (compute_array_index_type): Whenever we build a new index type
1130 to represent the size of an array in a template, we need to mark
1131 this index type as requiring structural equality. This goes for
1132 arrays with value-dependent sizes with the current ABI, or all
1134 * tree.c (cplus_array_hash): New.
1135 (struct cplus_array_info): New.
1136 (cplus_array_compare): New.
1137 (cplus_array_htab): New.
1138 (build_cplus_array_type_1): Use a hash table to cache the array
1139 types we build. Build the canonical array type for each array
1141 (cp_build_qualified_type_real): When building a cv-qualified array
1142 type, use the hash table of array types and build canonical array
1144 (bind_template_template_parm): BOUND_TEMPLATE_TEMPLATE_PARM nodes
1145 use structural equality (for now).
1146 * cp-tree.h (COMPARE_STRUCTURAL): New.
1147 * pt.c (canonical_template_parms): New.
1148 (canonical_type_parameter): New.
1149 (process_template_parm): Find the canonical type parameter.
1150 (lookup_template_class): When we have named the primary template
1151 type, set the canonical type for our template class to the primary
1152 template type. If any of the template arguments need structural
1153 equality checks, the template class needs structural equality
1155 (tsubst): When reducing the level of a template template
1156 parameter, we require structural equality tests for the resulting
1157 parameter because its template parameters have not had their types
1158 canonicalized. When reducing a template type parameter, find the
1159 canonical reduced type parameter.
1160 (any_template_arguments_need_structural_equality_p): New.
