Howard Hinnant 8e25104b10 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.

David Chisnall 18e33935f3 Some fixes to <atomic> operations to explicitly use atomic types and operations.

Howard Hinnant f3d14a65ca 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.

Howard Hinnant 9b0cd149aa 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.

Howard Hinnant 920b56ca88 Another installment on debug mode. This addresses list. However this should be considered a temporary state.

This was checked in without review. It is not clear its reasonable to

Alexis Hunt 1e846797dd Include an "implementation" if SGI's slist. This was quickly hacked
together to get it working with code, and is neither optimal
(erase(Iterator, Iterator) calculates the previous iterator twice,
rather than calculating the previous iterator of the first one, then
advancing it until the second is found) nor complete (splice() was not
implemented). Most of the implementation is borrowed from forward_list
via using-declarations.

2011-07-29 23:42:36 +00:00
Alexis Hunt 8324378195 Explicitly invoke the size_type specialization of max and min. This
avoids bugs where, when the allocator's size_type was smaller than int,
the multiplication or division would cause integral promotions and, with
two different integer types as arguments, deduction of the template
arguments would fail.

2011-07-29 23:31:58 +00:00
Alexis Hunt 8d2ed56644 Add a new hash class in __gnu_ext for the extension containers. There
are two motivations for this.

First, this allows users who are specializing __gnu_ext::hash to
continue doing so without changing their code.

Second, SGI specifies hash overloads for char* and const char* that
perform a hash of the string, not of the pointer.

In order to support this, the hashing code for string is factored out.

llvm-svn: 136539
2011-07-29 23:31:56 +00:00
Alexis Hunt fe473ae277 Add two missing members from the extension hash containers. The first is
the type name 'data_type', which is specified by the SGI spec as being
the correct type name for the mapped type. The second is an overload of
insert found in standard containers, taking an iterator as a 'hint'
(which we ignore in the standard containers as well). libstdc++'s
implementation includes these overloads, and they are needed to make
insert_iterator work (which I suspect is the real motivation for
including them in the standard containers).

The motivation for including these overloads of insert and leaving the
mapped_type typedef is to make it easier for clients to migrate to the
standard containers.

Alexis Hunt 8a02a632be Implement the __nolocale functions properly so that they will work on
all platforms. Unfortunately a lot of this remains conditionally
compiled so as not to break Apple's ABI.

them.

Alexis Hunt 3f60bca9e9 Implement generalized table lookups for upper, lower, and character
traits.

To the best of my knowledge, this will not break the ABI for Apple.
However, it does introduce three publicly visible (although with
reserved name) functions that will fail to link against the just-shipped
Apple version of libc++. Since they are not used in any inline
functions, no actual breakage should occur.

If Howard doesn't want to put undefined functions (even internal ones)
into a header, they could be surrounded by additional conditional
compilation.

Douglas Gregor 64ec101eb6 Teach libc++ about the addressof() overloads it needs to work with
Objective-C Automatic Reference Counting, where Objective-C object
pointers can have several different qualifiers (__strong, __weak,
__autoreleasing, __unsafe_unretained). These addressof() overloads are
only provided in ARC mode, and the __weak variant is conditionalized
on having weak-reference support in the ARC runtime.

For historical reasons, Clang provides these definitions itself, and
defines the macro _LIBCPP_PREDEFINED_OBJC_ARC_ADDRESSOF to note when
it as done so. The code belongs here, and this redundancy will be
eliminated in the future.

Addresses <rdar://problem/9658274>.

Howard Hinnant a945a32981 More fixes: One of my fixes to type_traits earlier today was incorrect, so that is reverted. Recently clang appears to have tightened up its definition of is_convertible and that has caused some failures in [unordered_][multi]map. I've switched to using is_constructible to restablish the desired functionality in [unordered_][multi]map. Specifically, inserting rvalues of move-only types for the keys.

Howard Hinnant 801291139c After sleeping on it I've decided that all special members that can be noexcept, should be declared so.

I've added a few extension noexcept to: allocator_traits<A>::deallocate, allocaate<T>::deallocate, return_temporary_buffer, and default_delete<T>::operator()(T*) const. My rationale was: If a std-dicated noexcept function needs to call another std-defined function, that called function must be noexcept. We're all a little new to noexcept, so things like this are to be expected. Also included fix for broken __is_swappable trait pointed out by Marc Glisse, thanks Marc|. And fixed a test case for is_nothrow_destructible. Destructors are now noexcept by default|
