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

The job of the thunk is to either adjust the this 3853 pointer before transferring control to the FUNCTION_DECL, or call 3854 FUNCTION_DECL and then adjust the result value.
