fuchsia-statically-constructed-objects¶
Warns if global, non-trivial objects with static storage are constructed, unless
the object is statically initialized with a constexpr
constructor or has no
explicit constructor.
For example:
class A {};
class B {
public:
B(int Val) : Val(Val) {}
private:
int Val;
};
class C {
public:
constexpr C(int Val) : Val(Val) {}
C(int Val1, int Val2) : Val(Val1+Val2) {}
private:
int Val;
};
static A a; // No warning, as there is no explicit constructor
static C c(0); // No warning, as constructor is constexpr
static B b(0); // Warning, as constructor is not constexpr
static C c2(0, 1); // Warning, as constructor is not constexpr
static int i; // No warning, as it is trivial
extern int get_i();
static C c3(get_i());// Warning, as the constructor is dynamically initialized
