149 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 | 150 | |
7ddedda4 MM |
151 | TYPE_ALIAS_SET |
152 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
153 | forth as a substitute for the mark bits provided in `lang_type'. | |
154 | At present, only the six low-order bits are used. | |
155 | ||
95b4aca6 | 156 | TYPE_LANG_SLOT_1 |
7ddedda4 | 157 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. |
6d0a3f67 | 158 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
0aafb128 | 159 | |
9df2c88c | 160 | BINFO_VIRTUALS |
bb5e8a7f MM |
161 | For a binfo, this is a TREE_LIST. There is an entry for each |
162 | virtual function declared either in BINFO or its direct and | |
163 | indirect primary bases. | |
164 | ||
165 | The BV_DELTA of each node gives the amount by which to adjust the | |
166 | `this' pointer when calling the function. If the method is an | |
4639c5c6 | 167 | overridden version of a base class method, then it is assumed |
bb5e8a7f MM |
168 | that, prior to adjustment, the this pointer points to an object |
169 | of the base class. | |
174eceea | 170 | |
5e19c053 | 171 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
19114537 | 172 | index of the vcall offset for this entry. |
c0bbf652 | 173 | |
5e19c053 | 174 | The BV_FN is the declaration for the virtual function itself. |
5e19c053 | 175 | |
02dea3ff JM |
176 | If BV_LOST_PRIMARY is set, it means that this entry is for a lost |
177 | primary virtual base and can be left null in the vtable. | |
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. */ | |

3808 | ||
3809 | A thunk is an alternate entry point for an ordinary FUNCTION_DECL. | |
3810 | The address of the ordinary FUNCTION_DECL is given by the | |
3811 | DECL_INITIAL, which is always an ADDR_EXPR whose operand is a | |
4977bab6 ZW |
3812 | FUNCTION_DECL. The job of the thunk is to either adjust the this |
3813 | pointer before transferring control to the FUNCTION_DECL, or call | |
3814 | FUNCTION_DECL and then adjust the result value. Note, the result | |
3815 | pointer adjusting thunk must perform a call to the thunked | |
3816 | function, (or be implemented via passing some invisible parameter | |
3817 | to the thunked function, which is modified to perform the | |
3818 | adjustment just before returning). | |
19114537 | 3819 | |
eb68cb58 MM |
3820 | A thunk may perform either, or both, of the following operations: |
3821 | ||
4977bab6 ZW |
3822 | o Adjust the this or result pointer by a constant offset. |
3823 | o Adjust the this or result pointer by looking up a vcall or vbase offset | |
eb68cb58 MM |
3824 | in the vtable. |
3825 | ||
4977bab6 ZW |
3826 | A this pointer adjusting thunk converts from a base to a derived |
3827 | class, and hence adds the offsets. A result pointer adjusting thunk | |
3828 | converts from a derived class to a base, and hence subtracts the | |
3829 | offsets. If both operations are performed, then the constant | |
34cd5ae7 | 3830 | adjustment is performed first for this pointer adjustment and last |
4977bab6 | 3831 | for the result pointer adjustment. |
eb68cb58 | 3832 | |
4977bab6 | 3833 | The constant adjustment is given by THUNK_FIXED_OFFSET. If the |
e00853fd NS |
3834 | vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |
3835 | used. For this pointer adjusting thunks, it is the vcall offset | |
3836 | into the vtable. For result pointer adjusting thunks it is the | |
3837 | binfo of the virtual base to convert to. Use that binfo's vbase | |
3838 | offset. | |
3839 | ||
3840 | It is possible to have equivalent covariant thunks. These are | |
3841 | distinct virtual covariant thunks whose vbase offsets happen to | |
3842 | have the same value. THUNK_ALIAS is used to pick one as the | |
