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

4404 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4405 The address of the ordinary FUNCTION_DECL is given by the
4406 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4407 FUNCTION_DECL. The job of the thunk is to either adjust the this
4408 pointer before transferring control to the FUNCTION_DECL, or call
4409 FUNCTION_DECL and then adjust the result value. Note, the result
4410 pointer adjusting thunk must perform a call to the thunked
4411 function, (or be implemented via passing some invisible parameter
4412 to the thunked function, which is modified to perform the
4413 adjustment just before returning).
4415 A thunk may perform either, or both, of the following operations:
4417 o Adjust the this or result pointer by a constant offset.
4418 o Adjust the this or result pointer by looking up a vcall or vbase offset
4421 A this pointer adjusting thunk converts from a base to a derived
4422 class, and hence adds the offsets. A result pointer adjusting thunk
4423 converts from a derived class to a base, and hence subtracts the
4424 offsets. If both operations are performed, then the constant
4425 adjustment is performed first for this pointer adjustment and last
4426 for the result pointer adjustment.
4428 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4429 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4430 used. For this pointer adjusting thunks, it is the vcall offset
4431 into the vtable. For result pointer adjusting thunks it is the
4432 binfo of the virtual base to convert to. Use that binfo's vbase
4435 It is possible to have equivalent covariant thunks. These are
4436 distinct virtual covariant thunks whose vbase offsets happen to
4437 have the same value. THUNK_ALIAS is used to pick one as the
4438 canonical thunk, which will get all the this pointer adjusting
