Take:
struct MyClass
{
};
typedef struct MyClass MyClass;
int Bar1( void ) __attribute__((warn_unused_result)) __attribute__((noinline));
MyClass Bar2( void ) __attribute__((warn_unused_result))
__attribute__((noinline));
int Bar1( void )
{
return 0;
}
MyClass Bar2( void )
{
}
void Foo( void )
{
Bar1(); // Warns
Bar2(); // Does not warn
}
--- CUT ---
In Foo, Bar1 and Bar2 should cause a warning, only Bar1 causes a warning with
the C++ front-end. While both cause a warning to show up with the C front-end.
