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

3233 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
3234 The address of the ordinary FUNCTION_DECL is given by the
3235 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3236 FUNCTION_DECL. The job of the thunk is to either adjust the this
3237 pointer before transferring control to the FUNCTION_DECL, or call
3238 FUNCTION_DECL and then adjust the result value. Note, the result
3239 pointer adjusting thunk must perform a call to the thunked
3240 function, (or be implemented via passing some invisible parameter
3241 to the thunked function, which is modified to perform the
3242 adjustment just before returning).
3244 A thunk may perform either, or both, of the following operations:
3246 o Adjust the this or result pointer by a constant offset.
3247 o Adjust the this or result pointer by looking up a vcall or vbase offset
3250 A this pointer adjusting thunk converts from a base to a derived
3251 class, and hence adds the offsets. A result pointer adjusting thunk
3252 converts from a derived class to a base, and hence subtracts the
3253 offsets. If both operations are performed, then the constant
3254 adjustment is performed first for this pointer adjustment and last
3255 for the result pointer adjustment.
3257 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3258 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3259 used. For this pointer adjusting thunks, it is the vcall offset
3260 into the vtable. For result pointer adjusting thunks it is the
3261 binfo of the virtual base to convert to. Use that binfo's vbase
3264 It is possible to have equivalent covariant thunks. These are
3265 distinct virtual covariant thunks whose vbase offsets happen to
3266 have the same value. THUNK_ALIAS is used to pick one as the
3267 canonical thunk, which will get all the this pointer adjusting
3268 thunks attached to it. */
