90 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
91 forth as a substitute for the mark bits provided in `lang_type'.
92 At present, only the six low-order bits are used.
95 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.

104 For a binfo, this is a TREE_LIST. The TREE_PURPOSE of each node
105 gives the amount by which to adjust the `this' pointer when
106 calling the function. The TREE_VALUE is the declaration for the
107 virtual function itself. When CLASSTYPE_COM_INTERFACE_P does not

2594 LOOKUP_NORMAL is just a combination of these two.
2595 LOOKUP_NONVIRTUAL means make a direct call to the member function found
2596 LOOKUP_GLOBAL means search through the space of overloaded functions,
2597 as well as the space of member functions.
2598 LOOKUP_HAS_IN_CHARGE means that the "in charge" variable is already
2599 in the parameter list.
2600 LOOKUP_ONLYCONVERTING means that non-conversion constructors are not tried.
2601 DIRECT_BIND means that if a temporary is created, it should be created so
2602 that it lives as long as the current variable bindings; otherwise it
2603 only lives until the end of the complete-expression.
2604 LOOKUP_SPECULATIVELY means return NULL_TREE if we cannot find what we are
2605 after. Note, LOOKUP_COMPLAIN is checked and error messages printed
2606 before LOOKUP_SPECULATIVELY is checked.
2607 LOOKUP_NO_CONVERSION means that user-defined conversions are not
2608 permitted. Built-in conversions are permitted.
2609 LOOKUP_DESTRUCTOR means explicit call to destructor.
2610 LOOKUP_NO_TEMP_BIND means temporaries will not be bound to references.
2612 These are used in global lookup to support elaborated types and
2615 LOOKUP_PREFER_TYPES means not to accept objects, and possibly namespaces.
2616 LOOKUP_PREFER_NAMESPACES means not to accept objects, and possibly types.
2617 LOOKUP_PREFER_BOTH means class-or-namespace-name.
2618 LOOKUP_TEMPLATES_EXPECTED means that class templates also count
