114 Usage of language-independent fields in a language-dependent manner:
117 This field is BINFO_INDIRECT_PRIMARY_P in a BINFO.
120 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
121 forth as a substitute for the mark bits provided in `lang_type'.
122 At present, only the six low-order bits are used.
125 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
126 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
129 For a binfo, this is a TREE_LIST. There is an entry for each
130 virtual function declared either in BINFO or its direct and
131 indirect primary bases.
133 The BV_DELTA of each node gives the amount by which to adjust the
134 `this' pointer when calling the function. If the method is an
135 overridden version of a base class method, then it is assumed
136 that, prior to adjustment, the this pointer points to an object
139 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
140 index of the vcall offset for this entry.
142 The BV_FN is the declaration for the virtual function itself.
145 This is an expression with POINTER_TYPE that gives the value
146 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
147 to extract the VAR_DECL for the complete vtable.
150 For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
153 This field is NULL for a non-virtual function. For a virtual
154 function, it is eventually set to an INTEGER_CST indicating the
155 index in the vtable at which this function can be found. When
156 a virtual function is declared, but before it is known what
157 function is overridden, this field is the error_mark_node.
159 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
160 the virtual function this one overrides, and whose TREE_CHAIN is
161 the old DECL_VINDEX. */

2865 The address of the ordinary FUNCTION_DECL is given by the
2866 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
2867 FUNCTION_DECL. The job of the thunk is to either adjust the this
2868 pointer before transferring control to the FUNCTION_DECL, or call
2869 FUNCTION_DECL and then adjust the result value. Note, the result
2870 pointer adjusting thunk must perform a call to the thunked
2871 function, (or be implemented via passing some invisible parameter
2872 to the thunked function, which is modified to perform the
2873 adjustment just before returning).
2875 A thunk may perform either, or both, of the following operations:
2877 o Adjust the this or result pointer by a constant offset.
2878 o Adjust the this or result pointer by looking up a vcall or vbase offset
2881 A this pointer adjusting thunk converts from a base to a derived
2882 class, and hence adds the offsets. A result pointer adjusting thunk
2883 converts from a derived class to a base, and hence subtracts the
2884 offsets. If both operations are performed, then the constant
2885 adjustment is performed first for this pointer adjustment and last
2886 for the result pointer adjustment.
2888 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
2889 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
2890 used. For this pointer adjusting thunks, it is the vcall offset
2891 into the vtable. For result pointer adjusting thunks it is the
2892 binfo of the virtual base to convert to. Use that binfo's vbase
2895 It is possible to have equivalent covariant thunks. These are
2896 distinct virtual covariant thunks whose vbase offsets happen to
2897 have the same value. THUNK_ALIAS is used to pick one as the
