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

2923 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
2924 The address of the ordinary FUNCTION_DECL is given by the
2925 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
2926 FUNCTION_DECL. The job of the thunk is to either adjust the this
2927 pointer before transferring control to the FUNCTION_DECL, or call
2928 FUNCTION_DECL and then adjust the result value. Note, the result
2929 pointer adjusting thunk must perform a call to the thunked
2930 function, (or be implemented via passing some invisible parameter
2931 to the thunked function, which is modified to perform the
2932 adjustment just before returning).
2934 A thunk may perform either, or both, of the following operations:
2936 o Adjust the this or result pointer by a constant offset.
2937 o Adjust the this or result pointer by looking up a vcall or vbase offset
2940 A this pointer adjusting thunk converts from a base to a derived
2941 class, and hence adds the offsets. A result pointer adjusting thunk
2942 converts from a derived class to a base, and hence subtracts the
2943 offsets. If both operations are performed, then the constant
2944 adjustment is performed first for this pointer adjustment and last
2945 for the result pointer adjustment.
2947 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
2948 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
2949 used. For this pointer adjusting thunks, it is the vcall offset
2950 into the vtable. For result pointer adjusting thunks it is the
2951 binfo of the virtual base to convert to. Use that binfo's vbase
2954 It is possible to have equivalent covariant thunks. These are
2955 distinct virtual covariant thunks whose vbase offsets happen to
2956 have the same value. THUNK_ALIAS is used to pick one as the
