245 Usage of language-independent fields in a language-dependent manner:
248 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
249 forth as a substitute for the mark bits provided in `lang_type'.
250 At present, only the six low-order bits are used.
253 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
254 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
257 For a binfo, this is a TREE_LIST. There is an entry for each
258 virtual function declared either in BINFO or its direct and
259 indirect primary bases.
261 The BV_DELTA of each node gives the amount by which to adjust the
262 `this' pointer when calling the function. If the method is an
263 overridden version of a base class method, then it is assumed
264 that, prior to adjustment, the this pointer points to an object
267 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
268 index of the vcall offset for this entry.
270 The BV_FN is the declaration for the virtual function itself.
272 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
273 primary virtual base and can be left null in the vtable.
276 This is an expression with POINTER_TYPE that gives the value
277 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
278 to extract the VAR_DECL for the complete vtable.
281 This field is NULL for a non-virtual function. For a virtual
282 function, it is eventually set to an INTEGER_CST indicating the
283 index in the vtable at which this function can be found. When
284 a virtual function is declared, but before it is known what
285 function is overridden, this field is the error_mark_node.
287 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
288 the virtual function this one overrides, and whose TREE_CHAIN is
289 the old DECL_VINDEX. */

4420 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4421 The address of the ordinary FUNCTION_DECL is given by the
4422 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4423 FUNCTION_DECL. The job of the thunk is to either adjust the this
4424 pointer before transferring control to the FUNCTION_DECL, or call
4425 FUNCTION_DECL and then adjust the result value. Note, the result
4426 pointer adjusting thunk must perform a call to the thunked
4427 function, (or be implemented via passing some invisible parameter
4428 to the thunked function, which is modified to perform the
4429 adjustment just before returning).
4431 A thunk may perform either, or both, of the following operations:
4433 o Adjust the this or result pointer by a constant offset.
4434 o Adjust the this or result pointer by looking up a vcall or vbase offset
4437 A this pointer adjusting thunk converts from a base to a derived
4438 class, and hence adds the offsets. A result pointer adjusting thunk
4439 converts from a derived class to a base, and hence subtracts the
4440 offsets. If both operations are performed, then the constant
4441 adjustment is performed first for this pointer adjustment and last
4442 for the result pointer adjustment.
4444 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4445 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4446 used. For this pointer adjusting thunks, it is the vcall offset
4447 into the vtable. For result pointer adjusting thunks it is the
4448 binfo of the virtual base to convert to. Use that binfo's vbase
4451 It is possible to have equivalent covariant thunks. These are
4452 distinct virtual covariant thunks whose vbase offsets happen to
4453 have the same value. THUNK_ALIAS is used to pick one as the
