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. */

2705 will be full instantiations.
2707 For a class template the DECL_TEMPLATE_INSTANTIATIONS lists holds
2708 all instantiations and specializations of the class type, including
2709 partial instantiations and partial specializations.
2711 In both cases, the TREE_PURPOSE of each node contains the arguments
2712 used; the TREE_VALUE contains the generated variable. The template
2713 arguments are always complete. For example, given:
2715 template <class T> struct S1 {
2716 template <class U> struct S2 {};
2717 template <class U> struct S2<U*> {};
2720 the record for the partial specialization will contain, as its
2721 argument list, { {T}, {U*} }, and will be on the
2722 DECL_TEMPLATE_INSTANTIATIONS list for `template <class T> template
2723 <class U> struct S1<T>::S2'.

2727 /* For a function template, the DECL_TEMPLATE_SPECIALIZATIONS lists

2729 including partial instantiations. For a partial instantiation
2730 which is a specialization, this list holds only full
2731 specializations of the template that are instantiations of the
2732 partial instantiation. For example, given:
2734 template <class T> struct S {
2735 template <class U> void f(U);
2736 template <> void f(T);
2739 the `S<int>::f<int>(int)' function will appear on the

2741 template <class U> void S<T>::f(U)' and `template <class T> void
2742 S<int>::f(T)'. In the latter case, however, it will have only the
2743 innermost set of arguments (T, in this case). The DECL_TI_TEMPLATE
2744 for the function declaration will point at the specialization, not
2745 the fully general template.
2747 For a class template, this list contains the partial
2748 specializations of this template. (Full specializations are not
2749 recorded on this list.) The TREE_PURPOSE holds the innermost
2750 arguments used in the partial specialization (e.g., for `template
2751 <class T> struct S<T*, int>' this will be `T*'.) The TREE_VALUE
2752 holds the innermost template parameters for the specialization
2753 (e.g., `T' in the example above.) The TREE_TYPE is the _TYPE node
2754 for the partial specialization.
