[libcxx] r299385 - suppress GCC warning about noexcept functions changing mangling

[Eric Fiselier via cfe-commits]

Here is a reduced version.

void glibc_function() throw() {}

template <class T> struct Test {
  Test() {} // expected-error {{mangled name for 'Test<T>::Test()' will
change in C++17}}
  ~Test() {}  // expected-error {{mangled name for 'Test<T>::~Test()' will
change in C++17}}
};

Test<decltype(&glibc_function)> t;
