152 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 | 153 | |
7ddedda4 MM |
154 | TYPE_ALIAS_SET |
155 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
156 | forth as a substitute for the mark bits provided in `lang_type'. | |
157 | At present, only the six low-order bits are used. | |
158 | ||
95b4aca6 | 159 | TYPE_LANG_SLOT_1 |
7ddedda4 | 160 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. |
6d0a3f67 | 161 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
0aafb128 | 162 | |
9df2c88c | 163 | BINFO_VIRTUALS |
bb5e8a7f MM |
164 | For a binfo, this is a TREE_LIST. There is an entry for each |
165 | virtual function declared either in BINFO or its direct and | |
166 | indirect primary bases. | |
167 | ||
168 | The BV_DELTA of each node gives the amount by which to adjust the | |
169 | `this' pointer when calling the function. If the method is an | |
4639c5c6 | 170 | overridden version of a base class method, then it is assumed |
bb5e8a7f MM |
171 | that, prior to adjustment, the this pointer points to an object |
172 | of the base class. | |
174eceea | 173 | |
5e19c053 | 174 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
19114537 | 175 | index of the vcall offset for this entry. |
c0bbf652 | 176 | |
5e19c053 | 177 | The BV_FN is the declaration for the virtual function itself. |
5e19c053 | 178 | |
c35cce41 | 179 | BINFO_VTABLE |
3461fba7 | 180 | This is an expression with POINTER_TYPE that gives the value |
c35cce41 | 181 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
3461fba7 | 182 | to extract the VAR_DECL for the complete vtable. |
c35cce41 | 183 | |
051e6fd7 MM |
184 | DECL_VINDEX |
185 | This field is NULL for a non-virtual function. For a virtual | |
186 | function, it is eventually set to an INTEGER_CST indicating the | |
187 | index in the vtable at which this function can be found. When | |
188 | a virtual function is declared, but before it is known what | |
4639c5c6 | 189 | function is overridden, this field is the error_mark_node. |
051e6fd7 | 190 | |
bb20cc46 | 191 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
051e6fd7 MM |
192 | the virtual function this one overrides, and whose TREE_CHAIN is |
193 | the old DECL_VINDEX. */ | |

3497 | ||
3498 | A thunk is an alternate entry point for an ordinary FUNCTION_DECL. | |
3499 | The address of the ordinary FUNCTION_DECL is given by the | |
3500 | DECL_INITIAL, which is always an ADDR_EXPR whose operand is a | |
4977bab6 ZW |
3501 | FUNCTION_DECL. The job of the thunk is to either adjust the this |
3502 | pointer before transferring control to the FUNCTION_DECL, or call | |
3503 | FUNCTION_DECL and then adjust the result value. Note, the result | |
3504 | pointer adjusting thunk must perform a call to the thunked | |
3505 | function, (or be implemented via passing some invisible parameter | |
3506 | to the thunked function, which is modified to perform the | |
3507 | adjustment just before returning). | |
19114537 | 3508 | |
eb68cb58 MM |
3509 | A thunk may perform either, or both, of the following operations: |
3510 | ||
4977bab6 ZW |
3511 | o Adjust the this or result pointer by a constant offset. |
3512 | o Adjust the this or result pointer by looking up a vcall or vbase offset | |
eb68cb58 MM |
3513 | in the vtable. |
3514 | ||
4977bab6 ZW |
3515 | A this pointer adjusting thunk converts from a base to a derived |
3516 | class, and hence adds the offsets. A result pointer adjusting thunk | |
3517 | converts from a derived class to a base, and hence subtracts the | |
3518 | offsets. If both operations are performed, then the constant | |
34cd5ae7 | 3519 | adjustment is performed first for this pointer adjustment and last |
4977bab6 | 3520 | for the result pointer adjustment. |
eb68cb58 | 3521 | |
4977bab6 | 3522 | The constant adjustment is given by THUNK_FIXED_OFFSET. If the |
e00853fd NS |
3523 | vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |
3524 | used. For this pointer adjusting thunks, it is the vcall offset | |
3525 | into the vtable. For result pointer adjusting thunks it is the | |
3526 | binfo of the virtual base to convert to. Use that binfo's vbase | |
3527 | offset. | |
3528 | ||
3529 | It is possible to have equivalent covariant thunks. These are | |
3530 | distinct virtual covariant thunks whose vbase offsets happen to | |
