There is an entry for each 132 virtual function declared either in BINFO or its direct and 133 indirect primary bases. 134 135 The BV_DELTA of each node gives the amount by which to adjust the 136 `this' pointer when calling the function. If the method is an 137 overridden version of a base class method, then it is assumed 138 that, prior to adjustment, the this pointer points to an object 139 of the base class. 140 141 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable 142 index of the vcall offset for this entry. 143 144 The BV_FN is the declaration for the virtual function itself. 145 146 BINFO_VTABLE 147 This is an expression with POINTER_TYPE that gives the value 148 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo 149 to extract the VAR_DECL for the complete vtable. 150 151 DECL_ARGUMENTS 152 For a VAR_DECL this is DECL_ANON_UNION_ELEMS. 153 154 DECL_VINDEX 155 This field is NULL for a non-virtual function. For a virtual 156 function, it is eventually set to an INTEGER_CST indicating the 157 index in the vtable at which this function can be found. When 158 a virtual function is declared, but before it is known what 159 function is overridden, this field is the error_mark_node. 160 161 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is 162 the virtual function this one overrides, and whose TREE_CHAIN is 163 the old DECL_VINDEX. */ 164 165 /* Language-specific tree checkers. */ 166 167 #define VAR_OR_FUNCTION_DECL_CHECK(NODE) \ 168 TREE_CHECK2(NODE,VAR_DECL,FUNCTION_DECL) 169 170 #define VAR_FUNCTION_OR_PARM_DECL_CHECK(NODE) \ 171 TREE_CHECK3(NODE,VAR_DECL,FUNCTION_DECL,PARM_DECL) 172 173 #define VAR_TEMPL_TYPE_OR_FUNCTION_DECL_CHECK(NODE) \ 174 TREE_CHECK4(NODE,VAR_DECL,FUNCTION_DECL,TYPE_DECL,TEMPLATE_DECL) 175 176 #define BOUND_TEMPLATE_TEMPLATE_PARM_TYPE_CHECK(NODE) \ 177 TREE_CHECK(NODE,BOUND_TEMPLATE_TEMPLATE_PARM) 178 179 #if defined ENABLE_TREE_CHECKING && (GCC_VERSION >= 2007) 180 #define NON_THUNK_FUNCTION_CHECK(NODE) __extension__ \ 181 ({ const tree __t = (NODE); \ 182 if (TREE_CODE (__t) != FUNCTION_DECL && \ 183 TREE_CODE (__t) != TEMPLATE_DECL && __t->decl_common.lang_specific \ 184 && __t->decl_common.lang_specific->decl_flags.thunk_p) \ 185 tree_check_failed (__t, __FILE__, __LINE__, __FUNCTION__, 0); \ 186 __t; }) 187 #define THUNK_FUNCTION_CHECK(NODE) __extension__ \ 188 ({ const tree __t = (NODE); \ 189 if (TREE_CODE (__t) != FUNCTION_DECL || !__t->decl_common.lang_specific \ 190 || !__t->decl_common.lang_specific->decl_flags.thunk_p) \ 191 tree_check_failed (__t, __FILE__, __LINE__, __FUNCTION__, 0); \ 192 __t; }) 193 #else 194 #define NON_THUNK_FUNCTION_CHECK(NODE) (NODE) 195 #define THUNK_FUNCTION_CHECK(NODE) (NODE) 196 #endif 197 198 /* Language-dependent contents of an identifier. */ 199 200 struct lang_identifier GTY(()) 201 { 202 struct c_common_identifier c_common; 203 cxx_binding *namespace_bindings; 204 cxx_binding *bindings; 205 tree class_template_info; 206 tree label_value; 207 }; 208 209 /* In an IDENTIFIER_NODE, nonzero if this identifier is actually a 210 keyword.
