523 Usage of language-independent fields in a language-dependent manner:
526 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
527 forth as a substitute for the mark bits provided in `lang_type'.
528 At present, only the six low-order bits are used.
531 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS.
532 For a POINTER_TYPE (to a METHOD_TYPE), this is TYPE_PTRMEMFUNC_TYPE.
533 For an ENUMERAL_TYPE, BOUND_TEMPLATE_TEMPLATE_PARM_TYPE,
534 RECORD_TYPE or UNION_TYPE this is TYPE_TEMPLATE_INFO,
537 For a binfo, this is a TREE_LIST. There is an entry for each
538 virtual function declared either in BINFO or its direct and
539 indirect primary bases.
541 The BV_DELTA of each node gives the amount by which to adjust the
542 `this' pointer when calling the function. If the method is an
543 overridden version of a base class method, then it is assumed
544 that, prior to adjustment, the this pointer points to an object
547 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
548 index of the vcall offset for this entry.
550 The BV_FN is the declaration for the virtual function itself.
552 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
553 primary virtual base and can be left null in the vtable.
556 This is an expression with POINTER_TYPE that gives the value
557 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
558 to extract the VAR_DECL for the complete vtable.
561 This field is NULL for a non-virtual function. For a virtual
562 function, it is eventually set to an INTEGER_CST indicating the
563 index in the vtable at which this function can be found. When
564 a virtual function is declared, but before it is known what
565 function is overridden, this field is the error_mark_node.
567 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
568 the virtual function this one overrides, and whose TREE_CHAIN is
569 the old DECL_VINDEX. */

4895 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4896 The address of the ordinary FUNCTION_DECL is given by the
4897 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4898 FUNCTION_DECL. The job of the thunk is to either adjust the this
4899 pointer before transferring control to the FUNCTION_DECL, or call
4900 FUNCTION_DECL and then adjust the result value. Note, the result
4901 pointer adjusting thunk must perform a call to the thunked
4902 function, (or be implemented via passing some invisible parameter
4903 to the thunked function, which is modified to perform the
4904 adjustment just before returning).
4906 A thunk may perform either, or both, of the following operations:
4908 o Adjust the this or result pointer by a constant offset.
4909 o Adjust the this or result pointer by looking up a vcall or vbase offset
4912 A this pointer adjusting thunk converts from a base to a derived
4913 class, and hence adds the offsets. A result pointer adjusting thunk
4914 converts from a derived class to a base, and hence subtracts the
4915 offsets. If both operations are performed, then the constant
4916 adjustment is performed first for this pointer adjustment and last
4917 for the result pointer adjustment.
4919 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4920 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4921 used. For this pointer adjusting thunks, it is the vcall offset
4922 into the vtable. For result pointer adjusting thunks it is the
4923 binfo of the virtual base to convert to. Use that binfo's vbase
4926 It is possible to have equivalent covariant thunks. These are
4927 distinct virtual covariant thunks whose vbase offsets happen to
4928 have the same value. THUNK_ALIAS is used to pick one as the
4929 canonical thunk, which will get all the this pointer adjusting
