TASKING VX-toolset for ARM User Guide

C++ Language• Functions can be "deleted". For example:int f(int) = delete;short f(short);int x = f(3);// Error: selected function is deleted.int y = f((short)3); // OK.• Special member functions can be explicitly "defaulted" (i.e., given a default definition). For example:struct S { S(S const&) = default; };struct T { T(T const&); };T::T(T const&) = default;• The operand of sizeof, typeid, or decltype can refer directly to a non-static data member of aclass without using a member access expression. For example:struct S {int i;};decltype(S::i) j = sizeof(S::i);• The keyword nullptr can be used as both a null pointer constant and a null pointer-to-memberconstant. Variables and other expressions whose type is that of the nullptr keyword (conventionallyknown by its standard typedef, std::nullptr_t) can also be used as null pointer(-to-member)constants, although they are only constant expressions if they otherwise would be. For example:#include // To get std::nullptr_tstruct S { };template struct X { };std::nullptr_t null();void f() {void *p = nullptr; // Initializes p to null pointerint S::* mp = nullptr; // Initializes mp to null ptr-to-memberp = null();// Sets p to null pointer}X xnull0;X xnull1;// Instantiates X with null int * value// Error: template argument not a// constant expression• Attributes delimited by double square brackets ([[ ... ]]) are accepted in declarations.The standardattributes align, noreturn, nothrow, final, and carries_dependency are supported. Forexample:[[nothrow]] void f();• Alias and alias template declarations are supported. For example:43
