1109 overflowed and operands did not.
1111 2007-01-05 Ian Lance Taylor <iant@google.com>
1113 * typeck.c (build_binary_op): Warn about comparing a non-weak
1116 2007-01-05 Douglas Gregor <doug.gregor@gmail.com>
1118 * pt.c (tsubst): Propagate the need for structural equality checks
1119 when reducing the level of template parameters.
1121 2007-01-03 Kazu Hirata <kazu@codesourcery.com>
1123 * pt.c: Fix a comment typo.
1125 2007-01-02 Ian Lance Taylor <iant@google.com>
1127 * semantics.c (maybe_convert_cond): Optionally warn when using an
1128 assignment as a condition.
1129 * typeck.c (convert_for_assignment): Optionally warn about
1130 assigning the result of an assignment to a bool.
1132 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
1134 * pt.c (canonical_template_parms): Correct typo in comment.
1136 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
1138 * typeck.c (structural_comptypes): Renamed from "comptypes".
1139 (comptypes): Use canonical type information to perform fast type
1140 comparison. When VERIFY_CANONICAL_TYPES, verify that the
1141 canonical type comparison returns the same results as we would see
1142 from the current, structural check. Support COMPARE_STRUCTURAL
1143 when we need structural checks.
1144 * decl.c (typename_compare): Fix comment.
1145 (build_typename_type): TYPENAME_TYPE nodes require structural
1146 equality checks, because they resolve different based on the
1148 (make_unbound_class_template): UNBOUND_CLASS_TEMPLATE nodes
1149 require structural equality checks (for now).
1150 (build_ptrmemfunc_type): Build the canonical pointer to member
1152 (compute_array_index_type): Whenever we build a new index type
1153 to represent the size of an array in a template, we need to mark
1154 this index type as requiring structural equality. This goes for
1155 arrays with value-dependent sizes with the current ABI, or all
1157 * tree.c (cplus_array_hash): New.
1158 (struct cplus_array_info): New.
1159 (cplus_array_compare): New.
1160 (cplus_array_htab): New.
1161 (build_cplus_array_type_1): Use a hash table to cache the array
1162 types we build. Build the canonical array type for each array
1164 (cp_build_qualified_type_real): When building a cv-qualified array
1165 type, use the hash table of array types and build canonical array
1167 (bind_template_template_parm): BOUND_TEMPLATE_TEMPLATE_PARM nodes
1168 use structural equality (for now).
1169 * cp-tree.h (COMPARE_STRUCTURAL): New.
1170 * pt.c (canonical_template_parms): New.
1171 (canonical_type_parameter): New.
1172 (process_template_parm): Find the canonical type parameter.
1173 (lookup_template_class): When we have named the primary template
1174 type, set the canonical type for our template class to the primary
1175 template type. If any of the template arguments need structural
1176 equality checks, the template class needs structural equality
1178 (tsubst): When reducing the level of a template template
1179 parameter, we require structural equality tests for the resulting
1180 parameter because its template parameters have not had their types
1181 canonicalized. When reducing a template type parameter, find the
1182 canonical reduced type parameter.
1183 (any_template_arguments_need_structural_equality_p): New.
