Roger Ferrer Ibanez 6f56d3eee8 [libcxx] Define istream_iterator equality comparison operators out-of-line ... Currently libc++ defines operator== and operator!= as friend functions in the definition of the istream_iterator class template. Such definition has a subtle difference from an out-of-line definition required by the C++ Standard: these functions can only be found by argument-dependent lookup, but not by qualified lookup. This patch changes the definition, so that it conforms to the C++ Standard and adds a check involving qualified lookup to the test suite. Patch contributed by Mikhail Maltsev.

iterator.container	More of P0600 - '[[nodiscard]] in the Library' mark empty() as nodiscard in string, string_view, and the free function std::empty(). Removed tabs from <string_view>, which is why the diff is so big.	2017-11-15 20:02:27 +00:00
