102 Usage of language-independent fields in a language-dependent manner:
105 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
106 forth as a substitute for the mark bits provided in `lang_type'.
107 At present, only the six low-order bits are used.
110 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
111 For a TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME.
112 For a TEMPLATE_TEMPLATE_PARM, this is
113 TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO.
116 For a binfo, this is a TREE_LIST. The BV_DELTA of each node
117 gives the amount by which to adjust the `this' pointer when
118 calling the function. If the method is an overriden version of a
119 base class method, then it is assumed that, prior to adjustment,
120 the this pointer points to an object of the base class.
122 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
123 index of the vcall offset for this entry.
125 The BV_FN is the declaration for the virtual function itself.
126 When CLASSTYPE_COM_INTERFACE_P does not hold, the first entry
127 does not have a BV_FN; it is just an offset.
129 The BV_OVERRIDING_BASE is the binfo for the final overrider for
130 this function. (This binfo's BINFO_TYPE will always be the same
131 as the DECL_CLASS_CONTEXT for the function.)
134 For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
137 This field is NULL for a non-virtual function. For a virtual
138 function, it is eventually set to an INTEGER_CST indicating the
139 index in the vtable at which this function can be found. When
140 a virtual function is declared, but before it is known what
141 function is overriden, this field is the error_mark_node.
143 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
144 the virtual function this one overrides, and whose TREE_CHAIN is
145 the old DECL_VINDEX. */

2704 DECL_TEMPLATE_INSTANTIATIONS list contains the explicitly and
2705 implicitly generated instantiations of the variable. There are no
2706 partial instantiations of static member variables, so all of these
2707 will be full instantiations.
2709 For a class template the DECL_TEMPLATE_INSTANTIATIONS lists holds
2710 all instantiations and specializations of the class type, including
2711 partial instantiations and partial specializations.
2713 In both cases, the TREE_PURPOSE of each node contains the arguments
2714 used; the TREE_VALUE contains the generated variable. The template
2715 arguments are always complete. For example, given:
2717 template <class T> struct S1 {
2718 template <class U> struct S2 {};
2719 template <class U> struct S2<U*> {};
2722 the record for the partial specialization will contain, as its
2723 argument list, { {T}, {U*} }, and will be on the
2724 DECL_TEMPLATE_INSTANTIATIONS list for `template <class T> template
2725 <class U> struct S1<T>::S2'.
2727 This list is not used for function templates. */

2729 /* For a function template, the DECL_TEMPLATE_SPECIALIZATIONS lists
2730 contains all instantiations and specializations of the function,
2731 including partial instantiations. For a partial instantiation
2732 which is a specialization, this list holds only full
2733 specializations of the template that are instantiations of the
2734 partial instantiation. For example, given:
2736 template <class T> struct S {
2737 template <class U> void f(U);
2738 template <> void f(T);
2741 the `S<int>::f<int>(int)' function will appear on the
2742 DECL_TEMPLATE_SPECIALIZATIONS list for both `template <class T>
2743 template <class U> void S<T>::f(U)' and `template <class T> void
2744 S<int>::f(T)'. In the latter case, however, it will have only the
2745 innermost set of arguments (T, in this case). The DECL_TI_TEMPLATE
2746 for the function declaration will point at the specialization, not
2747 the fully general template.
2749 For a class template, this list contains the partial
2750 specializations of this template. (Full specializations are not
2751 recorded on this list.) The TREE_PURPOSE holds the innermost
2752 arguments used in the partial specialization (e.g., for `template
2753 <class T> struct S<T*, int>' this will be `T*'.) The TREE_VALUE
2754 holds the innermost template parameters for the specialization
2755 (e.g., `T' in the example above.) The TREE_TYPE is the _TYPE node
2756 for the partial specialization.
