vector::emplace_back was mistakenly requiring move assignable.  Fixed that and did a little drive-by optimization at the same time.  This fixes http://llvm.org/bugs/show_bug.cgi?id=12085.

Hook up to the new clang __is_trivially_constructible and __is_trivially_assignable traits.  Fixes r10925427 and http://llvm.org/bugs/show_bug.cgi?id=12038.

Modernize conversion to bool to the explicit bool conversion operator (library wide).  This fixes http://llvm.org/bugs/show_bug.cgi?id=12058.

llvm-svn: 151088

Modernize relational operators for shared_ptr and unique_ptr.  This includes adding support for nullptr, and using less<T*>.  Fixes http://llvm.org/bugs/show_bug.cgi?id=12056.

Use __is_polymorphic if available.  This fixes http://llvm.org/bugs/show_bug.cgi?id=11983 .  Patch contributed by Jonathan Sauer.

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

Do not parse sign if a sign is not the next legal character when parsing floating point from an input stream.  Fixes http://llvm.org/bugs/show_bug.cgi?id=11871

Another stab at fixing http://llvm.org/bugs/show_bug.cgi?id=12007.  I earlier missed that there are two common_type definitions and corrected only one of them.

llvm-svn: 150599

Remove reference from common_type definition.  It looks like a recent clang decltype implementation got fixed/improved and exposed this.  Fixes http://llvm.org/bugs/show_bug.cgi?id=12007.

Provide a move(const T&) overload for C++03 mode to enable moving from rvalues.  This is to support proxy references.  Fixes r10858112.

Enable full functionality of shared_ptr<const void> by adding allocator<const void>.  Credit to John Hurley for discovering this bug.

1.  Fix make_shared<const T>.  2.  Allow allocator<const T> as an extension.  3.  Refactor work which fixed unique_ptr<const T[]>.  4.  Remove no-longer-needed private declarations from unique_ptr.  5.  Add constraints to some shared_ptr and weak_ptr constructors and assignment operators so that is_constructible/is_assignable give the correct answers for shared_ptr and weak_ptr.  6.  Make defensive preparations in the shared_ptr free functions for the introduction of shared_ptr<T[]> in the future.  7.  As an optimization, add move constructor and move assignment to weak_ptr.

The exception recovery mechanism for the uninitialized_* algorithms did not work for iterators into discontiguous memory.

The integral types now work with clang trunk (if you remove the guard), although we're still missing an intrinsic for initialising atomics (needed for C1x too).

Howard: Please review.

As an extension, support incomplete types in the unordered containers to match what we already do in the associative containers.

Starting using murmur2 when combining multiple size_t's into a single hash, and also for basic_string.  Also made hash<thread::id> ever so slighly more portable.  I had to tweak one test which is questionable (definitely not portable) anyway.

llvm-svn: 145795

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.

On FreeBSD, define a macro that causes the unimplemented C99 math.h functions to be declared.  This prevents <cmath> users from being broken, unless they actually use the C++ wrappers that call the missing functions.
