Howard Hinnant 6e41256f68 No functionality change at this time. I've split _LIBCPP_VISIBLE up into two flags: _LIBCPP_TYPE_VIS and _LIBCPP_FUNC_VIS. This is in preparation for taking advantage of clang's new __type_visibility__ attribute.

Howard Hinnant 0527c6207a I believe tuple is still under development in the standard. Daniel Krugler is/will be making convincing arguments that a modified form of LWG 2051 (currently NAD Future) is easily acheivable and desirable. He has demonstrated that a tuple<T...> where all of the T are implicitly convertible from U... should have a tuple constructor that is also implicit, instead of explicit. This would support the use cases in LWG 2051 while not undermining T... with explicit conversions from U.... This check-in is an experimental implementation of Daniel's work. I believe this work to be mature enough to warrant inclusion into libc++. If anyone sees real-world problems that this check in causes, please let me know and I will revert it, and provide the feedback to the LWG.

Howard Hinnant fa8df7db88 tuple was accidentally lacking a valid copy assignment operator. It went undetected because I had failed to test assigning from a const lvalue. This fixes http://llvm.org/bugs/show_bug.cgi?id=11921

Howard Hinnant bc95cf0d5f Experimental support for a meaningful __is_swappable<T>::value. This does not appear to be strictly needed for correct functioning of the library. If it causes any problems, I'd rather pull it sooner rather than later.

Howard Hinnant 27d0a2a75d noexcept for <tuple>. And in the process learned that I had done it wrong for pair's swap. I needed to create an __is_nothrow_swappable<T>::value trait that was smart enought to answer false when __is_swappable<T>::value is false. Otherwise one gets compile-time errors when using pair or tuple of non-swappable types, even if you never try to swap the pair or tuple.

Howard Hinnant 7f64810bc8 LWG 1385 [FCD] tuple_cat should be a single variadic signature (http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#1385). This issue is only in Ready status, meaning it is not official, but probably will be this March in Madrid. It was tentatively accepted in Batavia with the previso that Bill and I didn't have any problems implementing it. This is my part of that agreement.
