20// Helper macros for builtin compiler support.
21// If your compiler has builtin support for any of the following
22// traits concepts, then redefine the appropriate macros to pick
23// up on the compiler support:
24//
25// (these should largely ignore cv-qualifiers)
26// BOOST_IS_UNION(T) should evaluate to true if T is a union type
27// BOOST_IS_POD(T) should evaluate to true if T is a POD type
28// BOOST_IS_EMPTY(T) should evaluate to true if T is an empty class type (and not a union)
29// BOOST_HAS_TRIVIAL_CONSTRUCTOR(T) should evaluate to true if "T x;" has no effect
30// BOOST_HAS_TRIVIAL_COPY(T) should evaluate to true if T(t) <==> memcpy
31// BOOST_HAS_TRIVIAL_MOVE_CONSTRUCTOR(T) should evaluate to true if T(boost::move(t)) <==> memcpy
32// BOOST_HAS_TRIVIAL_ASSIGN(T) should evaluate to true if t = u <==> memcpy
33// BOOST_HAS_TRIVIAL_MOVE_ASSIGN(T) should evaluate to true if t = boost::move(u) <==> memcpy
34// BOOST_HAS_TRIVIAL_DESTRUCTOR(T) should evaluate to true if ~T() has no effect
35// BOOST_HAS_NOTHROW_CONSTRUCTOR(T) should evaluate to true if "T x;" can not throw
36// BOOST_HAS_NOTHROW_COPY(T) should evaluate to true if T(t) can not throw
37// BOOST_HAS_NOTHROW_ASSIGN(T) should evaluate to true if t = u can not throw
38// BOOST_HAS_VIRTUAL_DESTRUCTOR(T) should evaluate to true T has a virtual destructor
39// BOOST_IS_NOTHROW_MOVE_CONSTRUCT(T) should evaluate to true if T has a non-throwing move constructor.
40// BOOST_IS_NOTHROW_MOVE_ASSIGN(T) should evaluate to true if T has a non-throwing move assignment operator.
41//
42// The following can also be defined: when detected our implementation is greatly simplified.
43//
44// BOOST_IS_ABSTRACT(T) true if T is an abstract type
45// BOOST_IS_BASE_OF(T,U) true if T is a base class of U
46// BOOST_IS_CLASS(T) true if T is a class type (and not a union)
47// BOOST_IS_CONVERTIBLE(T,U) true if T is convertible to U
48// BOOST_IS_ENUM(T) true is T is an enum
49// BOOST_IS_POLYMORPHIC(T) true if T is a polymorphic type
50// BOOST_ALIGNMENT_OF(T) should evaluate to the alignment requirements of type T.
51//
52// define BOOST_TT_DISABLE_INTRINSICS to prevent any intrinsics being used (mostly used when testing)
