// Test for deduction of T as std::initializer_list. This isn't currently // supported by the working draft, but is necessary for perfect forwarding // of initializer-lists to things that can take a std::initializer_list. // { dg-options "-fdeduce-init-list" } // { dg-do run { target c++11 } } #include <initializer_list> struct A { A(std::initializer_list<int>) { } }; void f (A a) { } template <class T> auto g (T&& t) -> decltype (f(t)) // { dg-warning "call" } { return f(t); } int main() { g({1}); // { dg-warning "deduc" } } // { dg-prune-output "-fno-deduce-init-list" }
