### Clause [[dcl.decl]]: declarators <a id="diff.cpp14.decl">[[diff.cpp14.decl]]</a>
|
| 2 |
+
|
| 3 |
+
[[dcl.fct]] **Change:** Make exception specifications be part of the
|
| 4 |
+
type system. **Rationale:** Improve type-safety. **Effect on original
|
| 5 |
+
feature:** Valid C++14code may fail to compile or change meaning in this
|
| 6 |
+
International Standard:
|
| 7 |
+
|
| 8 |
+
``` cpp
|
| 9 |
+
void g1() noexcept;
|
| 10 |
+
void g2();
|
| 11 |
+
template<class T> int f(T *, T *);
|
| 12 |
+
int x = f(g1, g2); // ill-formed; previously well-formed
|
| 13 |
+
```
|
| 14 |
+
|
| 15 |
+
[[dcl.init.aggr]] **Change:** Definition of an aggregate is extended to
|
| 16 |
+
apply to user-defined types with base classes. **Rationale:** To
|
| 17 |
+
increase convenience of aggregate initialization. **Effect on original
|
| 18 |
+
feature:** Valid C++14code may fail to compile or produce different
|
| 19 |
+
results in this International Standard; initialization from an empty
|
| 20 |
+
initializer list will perform aggregate initialization instead of
|
| 21 |
+
invoking a default constructor for the affected types:
|
| 22 |
+
|
| 23 |
+
``` cpp
|
| 24 |
+
struct derived;
|
| 25 |
+
struct base {
|
| 26 |
+
friend struct derived;
|
| 27 |
+
private:
|
| 28 |
+
base();
|
| 29 |
+
};
|
| 30 |
+
struct derived : base {};
|
| 31 |
+
|
| 32 |
+
derived d1{}; // Error. The code was well-formed before.
|
| 33 |
+
derived d2; // still OK
|
| 34 |
+
```
