443 Usage of language-independent fields in a language-dependent manner:
446 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
447 forth as a substitute for the mark bits provided in `lang_type'.
448 At present, only the six low-order bits are used.
451 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
452 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
453 For a POINTER_TYPE (to a METHOD_TYPE), this is TYPE_PTRMEMFUNC_TYPE
456 For a binfo, this is a TREE_LIST. There is an entry for each
457 virtual function declared either in BINFO or its direct and
458 indirect primary bases.
460 The BV_DELTA of each node gives the amount by which to adjust the
461 `this' pointer when calling the function. If the method is an
462 overridden version of a base class method, then it is assumed
463 that, prior to adjustment, the this pointer points to an object
466 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
467 index of the vcall offset for this entry.
469 The BV_FN is the declaration for the virtual function itself.
471 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
472 primary virtual base and can be left null in the vtable.
475 This is an expression with POINTER_TYPE that gives the value
476 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
477 to extract the VAR_DECL for the complete vtable.
480 This field is NULL for a non-virtual function. For a virtual
481 function, it is eventually set to an INTEGER_CST indicating the
482 index in the vtable at which this function can be found. When
483 a virtual function is declared, but before it is known what
484 function is overridden, this field is the error_mark_node.
486 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
487 the virtual function this one overrides, and whose TREE_CHAIN is
488 the old DECL_VINDEX. */

4711 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4712 The address of the ordinary FUNCTION_DECL is given by the
4713 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4714 FUNCTION_DECL. The job of the thunk is to either adjust the this
4715 pointer before transferring control to the FUNCTION_DECL, or call
4716 FUNCTION_DECL and then adjust the result value. Note, the result
4717 pointer adjusting thunk must perform a call to the thunked
4718 function, (or be implemented via passing some invisible parameter
4719 to the thunked function, which is modified to perform the
4720 adjustment just before returning).
4722 A thunk may perform either, or both, of the following operations:
4724 o Adjust the this or result pointer by a constant offset.
4725 o Adjust the this or result pointer by looking up a vcall or vbase offset
4728 A this pointer adjusting thunk converts from a base to a derived
4729 class, and hence adds the offsets. A result pointer adjusting thunk
4730 converts from a derived class to a base, and hence subtracts the
4731 offsets. If both operations are performed, then the constant
4732 adjustment is performed first for this pointer adjustment and last
4733 for the result pointer adjustment.
4735 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4736 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4737 used. For this pointer adjusting thunks, it is the vcall offset
4738 into the vtable. For result pointer adjusting thunks it is the
4739 binfo of the virtual base to convert to. Use that binfo's vbase
4742 It is possible to have equivalent covariant thunks. These are
4743 distinct virtual covariant thunks whose vbase offsets happen to
4744 have the same value. THUNK_ALIAS is used to pick one as the
