| 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. |
| |
| If BV_LOST_PRIMARY is set, it means that this entry is for a lost |
| primary virtual base and can be left null in the vtable. |
| |
| 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. */ |
