The rules for emplace in map, multimap, unordered_map and unordered_multimap changed a while back and I'm just now updating to these new rules. In a nutshell, you've got to know you're emplacing to a pair and use one of pair's constructors. I made one extension: If you want to emplace the key and default construct the mapped_type, you can just emplace(key), as opposed to emplace(piecewise_construct, forward_as_tuple(key), forward_as_tuple()).

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.

Version #next on the hash functions for scalars. This builds on Dave's work, extends it to T*, and changes the way double and long double are handled (no longer convert to float on 32 bit). I also picked up a minor bug with uninitialized bits on the upper end of size_t when sizeof(size_t) > sizeof(T), e.g. in hash<float>. Most of the functionality has been put in one place: __scalar_hash in <memory>. Unfortunately I could not reuse __scalar_hash for hash<long double> on x86 because of the padding bits which need to be zeroed. I didn't want to add this zeroing step to the more general __scalar_hash when it isn't needed (in the absence of padding bits). I'm not ignoring the hash<string> issue (possibly changing that to a better hash). I just haven't gotten there yet.

Attempted locale refactoring. _LIBCPP_LOCALE__L_EXTENSIONS now should be defined if one has all of the xxx_l() functions. I've defined this for apple, freebsd and win32. _LIBCPP_HAS_DEFAULTRUNELOCALE should be defined if there is a _DefaultRuneLocale. I've defined this for apple and freebsd. The block of code we're trying to migrate away from is now under #ifdef __linux__. I've tested only on OS X. I hope I haven't broken things too badly elsewhere. Please let me know.

Another installment on debug mode. This addresses list. However this should be considered a temporary state. The API of the debug database and how vector and list use it, is unsatisfactory at the moment. It is both inefficient and overly verbose. I wanted to get this functionality checked in though. In the next day or so I'll refactor what is there in an attempt to streamline things.

libc++ now mostly works on FreeBSD with libcxxrt and this patch applied to the base system:

Chris Jefferson noted that vector iterator ownership can be transferred from source to target under move construction and move assignment. This commit makes that happen for debug mode.
