105 Usage of language-independent fields in a language-dependent manner:
108 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
109 forth as a substitute for the mark bits provided in `lang_type'.
110 At present, only the six low-order bits are used.
113 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
114 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
117 For a binfo, this is a TREE_LIST. There is an entry for each
118 virtual function declared either in BINFO or its direct and
119 indirect primary bases.
121 The BV_DELTA of each node gives the amount by which to adjust the
122 `this' pointer when calling the function. If the method is an
123 overridden version of a base class method, then it is assumed
124 that, prior to adjustment, the this pointer points to an object
127 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
128 index of the vcall offset for this entry.
130 The BV_FN is the declaration for the virtual function itself.
133 This is an expression with POINTER_TYPE that gives the value
134 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
135 to extract the VAR_DECL for the complete vtable.
138 For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
141 This field is NULL for a non-virtual function. For a virtual
142 function, it is eventually set to an INTEGER_CST indicating the
143 index in the vtable at which this function can be found. When
144 a virtual function is declared, but before it is known what
145 function is overridden, this field is the error_mark_node.
147 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
148 the virtual function this one overrides, and whose TREE_CHAIN is
149 the old DECL_VINDEX. */

2589 For a class template the DECL_TEMPLATE_INSTANTIATIONS lists holds
2590 all instantiations and specializations of the class type, including

2594 used; the TREE_VALUE contains the generated variable. The template
2595 arguments are always complete. For example, given:

2598 template <class U> struct S2 {};
2599 template <class U> struct S2<U*> {};
2602 the record for the partial specialization will contain, as its
2603 argument list, { {T}, {U*} }, and will be on the
2604 DECL_TEMPLATE_INSTANTIATIONS list for `template <class T> template
2605 <class U> struct S1<T>::S2'.

2777 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
2778 The address of the ordinary FUNCTION_DECL is given by the
2779 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
2780 FUNCTION_DECL. The job of the thunk is to either adjust the this
2781 pointer before transferring control to the FUNCTION_DECL, or call
2782 FUNCTION_DECL and then adjust the result value. Note, the result
2783 pointer adjusting thunk must perform a call to the thunked
2784 function, (or be implemented via passing some invisible parameter
2785 to the thunked function, which is modified to perform the
2786 adjustment just before returning).
2788 A thunk may perform either, or both, of the following operations:
2790 o Adjust the this or result pointer by a constant offset.
2791 o Adjust the this or result pointer by looking up a vcall or vbase offset
2794 A this pointer adjusting thunk converts from a base to a derived
2795 class, and hence adds the offsets. A result pointer adjusting thunk
2796 converts from a derived class to a base, and hence subtracts the
2797 offsets. If both operations are performed, then the constant
2798 adjustment is performed first for this pointer adjustment and last
2799 for the result pointer adjustment.
2801 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
2802 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
2803 used. For this pointer adjusting thunks, it is the vcall offset
2804 into the vtable. For result pointer adjusting thunks it is the
2805 binfo of the virtual base to convert to. Use that binfo's vbase
2808 It is possible to have equivalent covariant thunks. These are
2809 distinct virtual covariant thunks whose vbase offsets happen to
2810 have the same value. THUNK_ALIAS is used to pick one as the
