101 Usage of language-independent fields in a language-dependent manner:
104 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
105 forth as a substitute for the mark bits provided in `lang_type'.
106 At present, only the six low-order bits are used.
109 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
110 For a TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME.
111 For a TEMPLATE_TEMPLATE_PARM, this is
112 TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO.
114 DECL_SAVED_INSNS/DECL_FIELD_SIZE
115 For a static VAR_DECL, this is DECL_INIT_PRIORITY.
118 For a binfo, this is a TREE_LIST. The TREE_PURPOSE of each node
119 gives the amount by which to adjust the `this' pointer when
120 calling the function. The TREE_VALUE is the declaration for the
121 virtual function itself. When CLASSTYPE_COM_INTERFACE_P does not
122 hold, the first entry does not have a TREE_VALUE; it is just an
126 For a VAR_DECL this is DECL_ANON_UNION_ELEMS. */

3162 LOOKUP_ONLYCONVERTING means that non-conversion constructors are not tried.
3163 DIRECT_BIND means that if a temporary is created, it should be created so
3164 that it lives as long as the current variable bindings; otherwise it
3165 only lives until the end of the complete-expression.
3166 LOOKUP_SPECULATIVELY means return NULL_TREE if we cannot find what we are
3167 after. Note, LOOKUP_COMPLAIN is checked and error messages printed
3168 before LOOKUP_SPECULATIVELY is checked.
3169 LOOKUP_NO_CONVERSION means that user-defined conversions are not
3170 permitted. Built-in conversions are permitted.
3171 LOOKUP_DESTRUCTOR means explicit call to destructor.
3172 LOOKUP_NO_TEMP_BIND means temporaries will not be bound to references.
3174 These are used in global lookup to support elaborated types and
3177 LOOKUP_PREFER_TYPES means not to accept objects, and possibly namespaces.
3178 LOOKUP_PREFER_NAMESPACES means not to accept objects, and possibly types.
