160 | Usage of language-independent fields in a language-dependent manner: | |
d0ceae4d | 161 | |
e4e283ec | 162 | TYPE_ALIAS_SET |
163 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
164 | forth as a substitute for the mark bits provided in `lang_type'. | |
165 | At present, only the six low-order bits are used. | |
166 | ||
3cb98335 | 167 | TYPE_LANG_SLOT_1 |
e4e283ec | 168 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. |
8cbe13ee | 169 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
cec1f6a6 | 170 | |
ab7943b9 | 171 | BINFO_VIRTUALS |
641985fa | 172 | For a binfo, this is a TREE_LIST. There is an entry for each |
173 | virtual function declared either in BINFO or its direct and | |
174 | indirect primary bases. | |
175 | ||
176 | The BV_DELTA of each node gives the amount by which to adjust the | |
177 | `this' pointer when calling the function. If the method is an | |
e18c26dd | 178 | overridden version of a base class method, then it is assumed |
641985fa | 179 | that, prior to adjustment, the this pointer points to an object |
180 | of the base class. | |
8fcde9a9 | 181 | |
fc475736 | 182 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
ac13e8d9 | 183 | index of the vcall offset for this entry. |
7b4abb45 | 184 | |
fc475736 | 185 | The BV_FN is the declaration for the virtual function itself. |
fc475736 | 186 | |
0ec82042 | 187 | If BV_LOST_PRIMARY is set, it means that this entry is for a lost |
188 | primary virtual base and can be left null in the vtable. | |
189 | ||
59751e6c | 190 | BINFO_VTABLE |
5ad590ad | 191 | This is an expression with POINTER_TYPE that gives the value |
59751e6c | 192 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
5ad590ad | 193 | to extract the VAR_DECL for the complete vtable. |
59751e6c | 194 | |
d0d8836b | 195 | DECL_VINDEX |
196 | This field is NULL for a non-virtual function. For a virtual | |
197 | function, it is eventually set to an INTEGER_CST indicating the | |
198 | index in the vtable at which this function can be found. When | |
199 | a virtual function is declared, but before it is known what | |
e18c26dd | 200 | function is overridden, this field is the error_mark_node. |
d0d8836b | 201 | |
50cd3f45 | 202 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
d0d8836b | 203 | the virtual function this one overrides, and whose TREE_CHAIN is |
204 | the old DECL_VINDEX. */ | |

3939 | ||
3940 | A thunk is an alternate entry point for an ordinary FUNCTION_DECL. | |
3941 | The address of the ordinary FUNCTION_DECL is given by the | |
3942 | DECL_INITIAL, which is always an ADDR_EXPR whose operand is a | |
805e22b2 | 3943 | FUNCTION_DECL. The job of the thunk is to either adjust the this |
3944 | pointer before transferring control to the FUNCTION_DECL, or call | |
3945 | FUNCTION_DECL and then adjust the result value. Note, the result | |
3946 | pointer adjusting thunk must perform a call to the thunked | |
3947 | function, (or be implemented via passing some invisible parameter | |
3948 | to the thunked function, which is modified to perform the | |
3949 | adjustment just before returning). | |
ac13e8d9 | 3950 | |
a2697ab6 | 3951 | A thunk may perform either, or both, of the following operations: |
3952 | ||
805e22b2 | 3953 | o Adjust the this or result pointer by a constant offset. |
3954 | o Adjust the this or result pointer by looking up a vcall or vbase offset | |
a2697ab6 | 3955 | in the vtable. |
3956 | ||
805e22b2 | 3957 | A this pointer adjusting thunk converts from a base to a derived |
3958 | class, and hence adds the offsets. A result pointer adjusting thunk | |
3959 | converts from a derived class to a base, and hence subtracts the | |
3960 | offsets. If both operations are performed, then the constant | |
755edffd | 3961 | adjustment is performed first for this pointer adjustment and last |
805e22b2 | 3962 | for the result pointer adjustment. |
a2697ab6 | 3963 | |
805e22b2 | 3964 | The constant adjustment is given by THUNK_FIXED_OFFSET. If the |
6709b660 | 3965 | vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |
3966 | used. For this pointer adjusting thunks, it is the vcall offset | |
3967 | into the vtable. For result pointer adjusting thunks it is the | |
3968 | binfo of the virtual base to convert to. Use that binfo's vbase | |
3969 | offset. | |
3970 | ||
3971 | It is possible to have equivalent covariant thunks. These are | |
3972 | distinct virtual covariant thunks whose vbase offsets happen to | |
