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

3303 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
3304 The address of the ordinary FUNCTION_DECL is given by the
3305 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3306 FUNCTION_DECL. The job of the thunk is to either adjust the this
3307 pointer before transferring control to the FUNCTION_DECL, or call
3308 FUNCTION_DECL and then adjust the result value. Note, the result
3309 pointer adjusting thunk must perform a call to the thunked
3310 function, (or be implemented via passing some invisible parameter
3311 to the thunked function, which is modified to perform the
3312 adjustment just before returning).
3314 A thunk may perform either, or both, of the following operations:
3316 o Adjust the this or result pointer by a constant offset.
3317 o Adjust the this or result pointer by looking up a vcall or vbase offset
3320 A this pointer adjusting thunk converts from a base to a derived
3321 class, and hence adds the offsets. A result pointer adjusting thunk
3322 converts from a derived class to a base, and hence subtracts the
3323 offsets. If both operations are performed, then the constant
3324 adjustment is performed first for this pointer adjustment and last
3325 for the result pointer adjustment.
3327 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3328 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3329 used. For this pointer adjusting thunks, it is the vcall offset
3330 into the vtable. For result pointer adjusting thunks it is the
3331 binfo of the virtual base to convert to. Use that binfo's vbase
3334 It is possible to have equivalent covariant thunks. These are
3335 distinct virtual covariant thunks whose vbase offsets happen to
3336 have the same value. THUNK_ALIAS is used to pick one as the
