100 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
101 forth as a substitute for the mark bits provided in `lang_type'.
102 At present, only the six low-order bits are used.
105 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
106 For a TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME.
107 For a TEMPLATE_TEMPLATE_PARM, this is
108 TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO.
110 DECL_SAVED_INSNS/DECL_FIELD_SIZE
111 For a static VAR_DECL, this is DECL_INIT_PRIORITY.
114 For a binfo, this is a TREE_LIST. The TREE_PURPOSE of each node
115 gives the amount by which to adjust the `this' pointer when
116 calling the function. The TREE_VALUE is the declaration for the
117 virtual function itself. When CLASSTYPE_COM_INTERFACE_P does not
118 hold, the first entry does not have a TREE_VALUE; it is just an
