language-independent fields in a language-dependent manner: 156 157 TYPE_ALIAS_SET 158 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so 159 forth as a substitute for the mark bits provided in `lang_type'. 160 At present, only the six low-order bits are used. 161 162 TYPE_LANG_SLOT_1 163 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. 164 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS 165 166 BINFO_VIRTUALS 167 For a binfo, this is a TREE_LIST. There is an entry for each 168 virtual function declared either in BINFO or its direct and 169 indirect primary bases. 170 171 The BV_DELTA of each node gives the amount by which to adjust the 172 `this' pointer when calling the function. If the method is an 173 overridden version of a base class method, then it is assumed 174 that, prior to adjustment, the this pointer points to an object 175 of the base class. 176 177 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable 178 index of the vcall offset for this entry. 179 180 The BV_FN is the declaration for the virtual function itself. 181 182 If BV_LOST_PRIMARY is set, it means that this entry is for a lost 183 primary virtual base and can be left null in the vtable. 184 185 BINFO_VTABLE 186 This is an expression with POINTER_TYPE that gives the value 187 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo 188 to extract the VAR_DECL for the complete vtable. 189 190 DECL_VINDEX 191 This field is NULL for a non-virtual function. For a virtual 192 function, it is eventually set to an INTEGER_CST indicating the 193 index in the vtable at which this function can be found. When 194 a virtual function is declared, but before it is known what 195 function is overridden, this field is the error_mark_node. 196 197 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is 198 the virtual function this one overrides, and whose TREE_CHAIN is 199 the old DECL_VINDEX. */ 200 201/* Language-specific tree checkers. */ 202 203#define VAR_OR_FUNCTION_DECL_CHECK(NODE) \ 204 TREE_CHECK2(NODE,VAR_DECL,FUNCTION_DECL) 205 206#define TYPE_FUNCTION_OR_TEMPLATE_DECL_CHECK(NODE) \ 207 TREE_CHECK3(NODE,TYPE_DECL,TEMPLATE_DECL,FUNCTION_DECL) 208 209#define TYPE_FUNCTION_OR_TEMPLATE_DECL_P(NODE) \ 210 (TREE_CODE (NODE) == TYPE_DECL || TREE_CODE (NODE) == TEMPLATE_DECL \ 211 || TREE_CODE (NODE) == FUNCTION_DECL) 212 213#define VAR_FUNCTION_OR_PARM_DECL_CHECK(NODE) \ 214 TREE_CHECK3(NODE,VAR_DECL,FUNCTION_DECL,PARM_DECL) 215 216#define VAR_TEMPL_TYPE_OR_FUNCTION_DECL_CHECK(NODE) \ 217 TREE_CHECK4(NODE,VAR_DECL,FUNCTION_DECL,TYPE_DECL,TEMPLATE_DECL) 218 219#define VAR_TEMPL_TYPE_FIELD_OR_FUNCTION_DECL_CHECK(NODE) \ 220 TREE_CHECK5(NODE,VAR_DECL,FIELD_DECL,FUNCTION_DECL,TYPE_DECL,TEMPLATE_DECL) 221 222#define BOUND_TEMPLATE_TEMPLATE_PARM_TYPE_CHECK(NODE) \ 223 TREE_CHECK(NODE,BOUND_TEMPLATE_TEMPLATE_PARM) 224 225#if defined ENABLE_TREE_CHECKING && (GCC_VERSION >= 2007) 226#define THUNK_FUNCTION_CHECK(NODE) __extension__ \ 227({ __typeof (NODE) const __t = (NODE); \ 228 if (TREE_CODE (__t) != FUNCTION_DECL || !__t->decl_common.lang_specific \ 229 || !__t->decl_common.lang_specific->u.fn.thunk_p) \ 230 tree_check_failed (__t, __FILE__, __LINE__, __FUNCTION__, 0); \ 231 __t; }) 232#else 233#define THUNK_FUNCTION_CHECK(NODE) (NODE) 234#endif 235 236/* Language-dependent contents of an identifier. */ 237 238struct GTY(()) lang_identifier { 239 struct c_common_identifier c_common; 240 cxx_binding *namespace_bindings; 241 cxx_binding *bindings; 242 tree class_template_info; 243 tree label_value; 244}; 245 246/* In an IDENTIFIER_NODE, nonzero if this identifier is actually a 247 keyword.
