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

2949 The address of the ordinary FUNCTION_DECL is given by the
2950 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
2951 FUNCTION_DECL. The job of the thunk is to either adjust the this
2952 pointer before transferring control to the FUNCTION_DECL, or call
2953 FUNCTION_DECL and then adjust the result value. Note, the result
2954 pointer adjusting thunk must perform a call to the thunked
2955 function, (or be implemented via passing some invisible parameter
2956 to the thunked function, which is modified to perform the
2957 adjustment just before returning).

2961 o Adjust the this or result pointer by a constant offset.
2962 o Adjust the this or result pointer by looking up a vcall or vbase offset
2965 A this pointer adjusting thunk converts from a base to a derived
2966 class, and hence adds the offsets. A result pointer adjusting thunk
2967 converts from a derived class to a base, and hence subtracts the
2968 offsets. If both operations are performed, then the constant
2969 adjustment is performed first for this pointer adjustment and last
2970 for the result pointer adjustment.
2972 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
2973 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
2974 used. For this pointer adjusting thunks, it is the vcall offset
2975 into the vtable. For result pointer adjusting thunks it is the
2976 binfo of the virtual base to convert to. Use that binfo's vbase
2979 It is possible to have equivalent covariant thunks. These are
2980 distinct virtual covariant thunks whose vbase offsets happen to
2981 have the same value. THUNK_ALIAS is used to pick one as the
