176 | |
177 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 | 178 | |
7ddedda4 MM |
179 | TYPE_ALIAS_SET |
180 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
181 | forth as a substitute for the mark bits provided in `lang_type'. | |
182 | At present, only the six low-order bits are used. | |
183 | ||
95b4aca6 | 184 | TYPE_LANG_SLOT_1 |
7ddedda4 | 185 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. |
6d0a3f67 | 186 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
0aafb128 | 187 | |
9df2c88c | 188 | BINFO_VIRTUALS |
bb5e8a7f MM |
189 | For a binfo, this is a TREE_LIST. There is an entry for each |
190 | virtual function declared either in BINFO or its direct and | |
191 | indirect primary bases. | |
192 | ||
193 | The BV_DELTA of each node gives the amount by which to adjust the | |
194 | `this' pointer when calling the function. If the method is an | |
4639c5c6 | 195 | overridden version of a base class method, then it is assumed |
bb5e8a7f MM |
196 | that, prior to adjustment, the this pointer points to an object |
197 | of the base class. | |
174eceea | 198 | |
5e19c053 | 199 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
19114537 | 200 | index of the vcall offset for this entry. |
c0bbf652 | 201 | |
5e19c053 | 202 | The BV_FN is the declaration for the virtual function itself. |
5e19c053 | 203 | |
02dea3ff JM |
204 | If BV_LOST_PRIMARY is set, it means that this entry is for a lost |
205 | primary virtual base and can be left null in the vtable. | |
206 | ||
c35cce41 | 207 | BINFO_VTABLE |
3461fba7 | 208 | This is an expression with POINTER_TYPE that gives the value |
c35cce41 | 209 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
3461fba7 | 210 | to extract the VAR_DECL for the complete vtable. |
c35cce41 | 211 | |
051e6fd7 MM |
212 | DECL_VINDEX |
213 | This field is NULL for a non-virtual function. For a virtual | |
214 | function, it is eventually set to an INTEGER_CST indicating the | |
215 | index in the vtable at which this function can be found. When | |
216 | a virtual function is declared, but before it is known what | |
4639c5c6 | 217 | function is overridden, this field is the error_mark_node. |
051e6fd7 | 218 | |
bb20cc46 | 219 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
051e6fd7 MM |
220 | the virtual function this one overrides, and whose TREE_CHAIN is |
221 | the old DECL_VINDEX. */ | |

4318 | /* A thunk is a stub function. |
4319 | ||
4320 | A thunk is an alternate entry point for an ordinary FUNCTION_DECL. | |
4321 | The address of the ordinary FUNCTION_DECL is given by the | |
4322 | DECL_INITIAL, which is always an ADDR_EXPR whose operand is a | |
4977bab6 ZW |
4323 | FUNCTION_DECL. The job of the thunk is to either adjust the this |
4324 | pointer before transferring control to the FUNCTION_DECL, or call | |
4325 | FUNCTION_DECL and then adjust the result value. Note, the result | |
4326 | pointer adjusting thunk must perform a call to the thunked | |
4327 | function, (or be implemented via passing some invisible parameter | |
4328 | to the thunked function, which is modified to perform the | |
4329 | adjustment just before returning). | |
19114537 | 4330 | |
eb68cb58 MM |
4331 | A thunk may perform either, or both, of the following operations: |
4332 | ||
4977bab6 ZW |
4333 | o Adjust the this or result pointer by a constant offset. |
4334 | o Adjust the this or result pointer by looking up a vcall or vbase offset | |
eb68cb58 MM |
4335 | in the vtable. |
4336 | ||
4977bab6 ZW |
4337 | A this pointer adjusting thunk converts from a base to a derived |
4338 | class, and hence adds the offsets. A result pointer adjusting thunk | |
4339 | converts from a derived class to a base, and hence subtracts the | |
4340 | offsets. If both operations are performed, then the constant | |
34cd5ae7 | 4341 | adjustment is performed first for this pointer adjustment and last |
4977bab6 | 4342 | for the result pointer adjustment. |
eb68cb58 | 4343 | |
4977bab6 | 4344 | The constant adjustment is given by THUNK_FIXED_OFFSET. If the |
e00853fd NS |
4345 | vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |
4346 | used. For this pointer adjusting thunks, it is the vcall offset | |
4347 | into the vtable. For result pointer adjusting thunks it is the | |
4348 | binfo of the virtual base to convert to. Use that binfo's vbase | |
4349 | offset. | |
4350 | ||
4351 | It is possible to have equivalent covariant thunks. These are | |
4352 | distinct virtual covariant thunks whose vbase offsets happen to | |
4353 | have the same value. THUNK_ALIAS is used to pick one as the | |
4354 | canonical thunk, which will get all the this pointer adjusting | |
4355 | thunks attached to it. */ | |
