// - the "previous" (temporal) element in the chain
// - the "latest" (temporal) element in the chain
// - the an "uninitialized-latest" value (when newly-constructed)

// - The first element is also often called the canonical element. Every

// - Most links in the chain point to previous, except the link out of

// - Elements are called "first", "previous", "latest" or

// - To make matters confusing, the DeclLink type uses the term "next"

// NextIsPrevious). It's easiest to just ignore the implementation of
// DeclLink when making sense of the redeclaration chain.
//
// - There's also a "definition" link for several types of

for ``T`` and ``U`` to be incompatible.
The declaration of ``overloadable`` functions is restricted to function
declarations and definitions. Most importantly, if any function with a given
name is given the ``overloadable`` attribute, then all function declarations
and definitions with that name (and in that scope) must have the
``overloadable`` attribute. This rule even applies to redeclarations of
functions whose original declaration had the ``overloadable`` attribute, e.g.,
declarations and definitions. If a function is marked with the ``overloadable``
attribute, then all declarations and definitions of functions with that name,
except for at most one (see the note below about unmarked overloads), must have
the ``overloadable`` attribute. In addition, redeclarations of a function with
the ``overloadable`` attribute must have the ``overloadable`` attribute, and
redeclarations of a function without the ``overloadable`` attribute must *not*
have the ``overloadable`` attribute. e.g.,
.. code-block:: c
int f(int) __attribute__((overloadable));
float f(float); // error: declaration of "f" must have the "overloadable" attribute
int f(int); // error: redeclaration of "f" must have the "overloadable" attribute
int g(int) __attribute__((overloadable));
int g(int) { } // error: redeclaration of "g" must also have the "overloadable" attribute
int h(int);
int h(int) __attribute__((overloadable)); // error: declaration of "h" must not
// have the "overloadable" attribute

following code is ill-formed:

linkage specification, it's name *will* be mangled in the same way as it
would in C.
Query for this feature with ``__has_extension(attribute_overloadable)``.
For the purpose of backwards compatibility, at most one function with the same
name as other ``overloadable`` functions may omit the ``overloadable``
attribute. In this case, the function without the ``overloadable`` attribute
will not have its name mangled.
For example:
.. code-block:: c
// Notes with mangled names assume Itanium mangling.
int f(int);
int f(double) __attribute__((overloadable));
void foo() {
f(5); // Emits a call to f (not _Z1fi, as it would with an overload that
// was marked with overloadable).
f(1.0); // Emits a call to _Z1fd.
}
Support for unmarked overloads is not present in some versions of clang. You may
query for it using ``__has_extension(overloadable_unmarked)``.
