e4e283ec | 108 | |
109 | Usage of language-independent fields in a language-dependent manner: | |
d0ceae4d | 110 | |
111 | TREE_USED | |
112 | This field is BINFO_INDIRECT_PRIMARY_P in a BINFO. | |
113 | ||
e4e283ec | 114 | TYPE_ALIAS_SET |
115 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
116 | forth as a substitute for the mark bits provided in `lang_type'. | |
117 | At present, only the six low-order bits are used. | |
118 | ||
119 | TYPE_BINFO | |
120 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. | |
8cbe13ee | 121 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
cec1f6a6 | 122 | |
ab7943b9 | 123 | BINFO_VIRTUALS |
fc475736 | 124 | For a binfo, this is a TREE_LIST. The BV_DELTA of each node |
5355cb60 | 125 | gives the amount by which to adjust the `this' pointer when |
8fcde9a9 | 126 | calling the function. If the method is an overriden version of a |
127 | base class method, then it is assumed that, prior to adjustment, | |
128 | the this pointer points to an object of the base class. | |
129 | ||
fc475736 | 130 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
2b82dde2 | 131 | index of the vcall offset for this entry. If |
132 | BV_USE_VCALL_INDEX_P then the corresponding vtable entry should | |
133 | use a virtual thunk, as opposed to an ordinary thunk. | |
7b4abb45 | 134 | |
fc475736 | 135 | The BV_FN is the declaration for the virtual function itself. |
fc475736 | 136 | |
59751e6c | 137 | BINFO_VTABLE |
5ad590ad | 138 | This is an expression with POINTER_TYPE that gives the value |
59751e6c | 139 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
5ad590ad | 140 | to extract the VAR_DECL for the complete vtable. |
59751e6c | 141 | |
74c333de | 142 | DECL_ARGUMENTS |
50cd3f45 | 143 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. |
d0d8836b | 144 | |
145 | DECL_VINDEX | |
146 | This field is NULL for a non-virtual function. For a virtual | |
147 | function, it is eventually set to an INTEGER_CST indicating the | |
148 | index in the vtable at which this function can be found. When | |
149 | a virtual function is declared, but before it is known what | |
150 | function is overriden, this field is the error_mark_node. | |
151 | ||
50cd3f45 | 152 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
d0d8836b | 153 | the virtual function this one overrides, and whose TREE_CHAIN is |
154 | the old DECL_VINDEX. */ | |
