DECL_THUNK_P (in a member FUNCTION_DECL)
Usage of language-independent fields in a language-dependent manner:
TREE_USED
This field is BINFO_INDIRECT_PRIMARY_P in a BINFO.
TYPE_ALIAS_SET
This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
forth as a substitute for the mark bits provided in `lang_type'.
At present, only the six low-order bits are used.
TYPE_BINFO
For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
BINFO_VIRTUALS
For a binfo, this is a TREE_LIST. The BV_DELTA of each node
gives the amount by which to adjust the `this' pointer when
calling the function. If the method is an overriden version of a
base class method, then it is assumed that, prior to adjustment,
the this pointer points to an object of the base class.
The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
index of the vcall offset for this entry. If
BV_USE_VCALL_INDEX_P then the corresponding vtable entry should
use a virtual thunk, as opposed to an ordinary thunk.
The BV_FN is the declaration for the virtual function itself.
BINFO_VTABLE
This is an expression with POINTER_TYPE that gives the value
to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
to extract the VAR_DECL for the complete vtable.
DECL_ARGUMENTS
For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
DECL_VINDEX
This field is NULL for a non-virtual function. For a virtual
function, it is eventually set to an INTEGER_CST indicating the
index in the vtable at which this function can be found. When
a virtual function is declared, but before it is known what
function is overriden, this field is the error_mark_node.
Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
the virtual function this one overrides, and whose TREE_CHAIN is
the old DECL_VINDEX. */

/* These are uses as bits in flags passed to build_method_call

LOOKUP_PROTECT means flag access violations.
LOOKUP_COMPLAIN mean complain if no suitable member function
matching the arguments is found.
LOOKUP_NORMAL is just a combination of these two.
LOOKUP_NONVIRTUAL means make a direct call to the member function found
LOOKUP_GLOBAL means search through the space of overloaded functions,
as well as the space of member functions.
LOOKUP_ONLYCONVERTING means that non-conversion constructors are not tried.
DIRECT_BIND means that if a temporary is created, it should be created so
that it lives as long as the current variable bindings; otherwise it
only lives until the end of the complete-expression. It also forces
direct-initialization in cases where other parts of the compiler have
already generated a temporary, such as reference initialization and the
catch parameter.
LOOKUP_SPECULATIVELY means return NULL_TREE if we cannot find what we are
after. Note, LOOKUP_COMPLAIN is checked and error messages printed
before LOOKUP_SPECULATIVELY is checked.
LOOKUP_NO_CONVERSION means that user-defined conversions are not
permitted. Built-in conversions are permitted.
LOOKUP_DESTRUCTOR means explicit call to destructor.
LOOKUP_NO_TEMP_BIND means temporaries will not be bound to references.
These are used in global lookup to support elaborated types and
qualifiers.
LOOKUP_PREFER_TYPES means not to accept objects, and possibly namespaces.
LOOKUP_PREFER_NAMESPACES means not to accept objects, and possibly types.
LOOKUP_PREFER_BOTH means class-or-namespace-name.
LOOKUP_TEMPLATES_EXPECTED means that class templates also count
as types. */
