[^1]: There is no special provision for a *decl-specifier-seq* that
|
| 270 |
-
lacks a *type-specifier* or that has a *type-specifier* that only
|
| 271 |
-
specifies *cv-qualifier*s. The “implicit int” rule of C is no longer
|
| 272 |
-
supported.
|
| 273 |
-
|
| 274 |
-
[^2]: As indicated by syntax, cv-qualifiers are a significant component
|
| 275 |
-
in function return types.
|
| 276 |
-
|
| 277 |
-
[^3]: One can explicitly disambiguate the parse either by introducing a
|
| 278 |
-
comma (so the ellipsis will be parsed as part of the
|
| 279 |
-
*parameter-declaration-clause*) or by introducing a name for the
|
| 280 |
-
parameter (so the ellipsis will be parsed as part of the
|
| 281 |
-
*declarator-id*).
|
| 282 |
-
|
| 283 |
-
[^4]: This means that default arguments cannot appear, for example, in
|
| 284 |
-
declarations of pointers to functions, references to functions, or
|
| 285 |
-
`typedef` declarations.
|
| 286 |
-
|
| 287 |
-
[^5]: As specified in [[conv.ptr]], converting an integer literal whose
|
| 288 |
-
value is `0` to a pointer type results in a null pointer value.
|
| 289 |
-
|
| 290 |
-
[^6]: The syntax provides for empty *braced-init-list*s, but nonetheless
|
| 291 |
-
C++ does not have zero length arrays.
|
| 292 |
-
|
| 293 |
-
[^7]: This requires a conversion function [[class.conv.fct]] returning a
|
| 294 |
-
reference type.
|
| 295 |
-
|
| 296 |
-
[^8]: Implementations are permitted to provide additional predefined
|
| 297 |
-
variables with names that are reserved to the implementation
|
| 298 |
-
[[lex.name]]. If a predefined variable is not odr-used
|
| 299 |
-
[[term.odr.use]], its string value need not be present in the
|
| 300 |
-
program image.

[^9]: This set of values is used to define promotion and conversion
|
| 303 |
-
semantics for the enumeration type. It does not preclude an
|
| 304 |
-
expression of enumeration type from having a value that falls
|
| 305 |
-
outside this range.

[^10]: During name lookup in a class hierarchy, some ambiguities can be
|
| 308 |
-
resolved by considering whether one member hides the other along
|
| 309 |
-
some paths [[class.member.lookup]]. There is no such
|
| 310 |
-
disambiguation when considering the set of names found as a result
|
| 311 |
-
of following \*using-directive\*s.
|
| 312 |
-
|
| 313 |
-
[^11]: A *using-declaration* with more than one *using-declarator* is
|
| 314 |
-
equivalent to a corresponding sequence of *using-declaration*s with
|
| 315 |
-
one *using-declarator* each.

[*Note 1*: The non-static data member can share the address of another
|
| 9 |
non-static data member or that of a base class, and any padding that
|
| 10 |
would normally be inserted at the end of the object can be reused as
|
| 11 |
storage for other members. — *end note*]
|
| 12 |
|

*Recommended practice:* The value of a *has-attribute-expression* for
|
| 14 |
+
the `no_unique_address` attribute should be `0` for a given
|
| 15 |
+
implementation unless this attribute can cause a potentially-overlapping
|
| 16 |
+
subobject to have zero size.

[*Example 1*:
|
| 19 |
|
| 20 |
``` cpp
|
| 21 |
template<typename Key, typename Value,
|
| 22 |
typename Hash, typename Pred, typename Allocator>
|
|
|
|
| 34 |
Here, `hasher`, `pred`, and `alloc` could have the same address as
|
| 35 |
`buckets` if their respective types are all empty.
