| Usage of language-independent fields in a language-dependent manner: |
| |
| TYPE_ALIAS_SET |
| This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so |
| forth as a substitute for the mark bits provided in `lang_type'. |
| At present, only the six low-order bits are used. |
| |
| TYPE_LANG_SLOT_1 |
| For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. |
| For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
| |
| BINFO_VIRTUALS |
| For a binfo, this is a TREE_LIST. There is an entry for each |
| virtual function declared either in BINFO or its direct and |
| indirect primary bases. |
| |
| The BV_DELTA of each node gives the amount by which to adjust the |
| `this' pointer when calling the function. If the method is an |
| overridden version of a base class method, then it is assumed |
| that, prior to adjustment, the this pointer points to an object |
| of the base class. |
| |
| The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
| index of the vcall offset for this entry. |
| |
| The BV_FN is the declaration for the virtual function itself. |
| |
| BINFO_VTABLE |
| This is an expression with POINTER_TYPE that gives the value |
| to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
| to extract the VAR_DECL for the complete vtable. |
| |
| DECL_VINDEX |
| This field is NULL for a non-virtual function. For a virtual |
| function, it is eventually set to an INTEGER_CST indicating the |
| index in the vtable at which this function can be found. When |
| a virtual function is declared, but before it is known what |
| function is overridden, this field is the error_mark_node. |
| |
| Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
| the virtual function this one overrides, and whose TREE_CHAIN is |
| the old DECL_VINDEX. */ |

| /* A thunk is a stub function. |
| |
| A thunk is an alternate entry point for an ordinary FUNCTION_DECL. |
| The address of the ordinary FUNCTION_DECL is given by the |
| DECL_INITIAL, which is always an ADDR_EXPR whose operand is a |
| FUNCTION_DECL. The job of the thunk is to either adjust the this |
| pointer before transferring control to the FUNCTION_DECL, or call |
| FUNCTION_DECL and then adjust the result value. Note, the result |
| pointer adjusting thunk must perform a call to the thunked |
| function, (or be implemented via passing some invisible parameter |
| to the thunked function, which is modified to perform the |
| adjustment just before returning). |
| |
| A thunk may perform either, or both, of the following operations: |
| |
| o Adjust the this or result pointer by a constant offset. |
| o Adjust the this or result pointer by looking up a vcall or vbase offset |
| in the vtable. |
| |
| A this pointer adjusting thunk converts from a base to a derived |
| class, and hence adds the offsets. A result pointer adjusting thunk |
| converts from a derived class to a base, and hence subtracts the |
| offsets. If both operations are performed, then the constant |
| adjustment is performed first for this pointer adjustment and last |
| for the result pointer adjustment. |
| |
| The constant adjustment is given by THUNK_FIXED_OFFSET. If the |
| vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |
| used. For this pointer adjusting thunks, it is the vcall offset |
| into the vtable. For result pointer adjusting thunks it is the |
| binfo of the virtual base to convert to. Use that binfo's vbase |
| offset. |
| |
| It is possible to have equivalent covariant thunks. These are |
| distinct virtual covariant thunks whose vbase offsets happen to |
| have the same value. THUNK_ALIAS is used to pick one as the |
| canonical thunk, which will get all the this pointer adjusting |
