Howard Hinnant 423a8d7733 Fix several bugs in find/count specialized for bits.
llvm-svn: 156546
2012-05-10 14:55:00 +00:00
Howard Hinnant 19d9cbfb39 Add friends __count_bool_true and __count_bool_false to __bit_iterator.
llvm-svn: 156543
2012-05-10 14:01:40 +00:00
Howard Hinnant 0ae9efeb1a SFINAE __bit_iterator such that it will only get instantiated with a container that has the nested type __storage_type. This prevents accidental instantiation such as in http://llvm.org/bugs/show_bug.cgi?id=12755. This fixes http://llvm.org/bugs/show_bug.cgi?id=12755.

Howard Hinnant df7aad41fd Constrain __bind functor constructor such that it won't accidentally get used as a copy constructor from a non-const lvalue. Fixes <rdar://problem/11359080>.

Howard Hinnant 9acfc3af72 Change std::abs from a template function to three overloads for float, double and long double.

Howard Hinnant bff1bfc6be Greatly scale back ambitions of emulating move semantics in C++03 mode. It was causing more problems than it solved. This fixes http://llvm.org/bugs/show_bug.cgi?id=12704.

Howard Hinnant d01320c200 Apply noexcept and constexpr to <atomic>.
llvm-svn: 154526
2012-04-11 20:14:21 +00:00
Richard Smith 766e8ccbfc Switch libc++ from __atomic_* builtins to __c11_atomic_* builtins.
Per discussion with Howard, we are not interested in maintaining
compatibility with older versions of clang.

All tests pass with ToT clang, except for two which assert due to
a pre-existing, unrelated bug.

David Chisnall cd42f9446b Now that clang supports doing the right thing with regard to atomic
initialisation, do the right thing with regard to atomic initialisation.

Note: clang r154507 or later required for <atomic> to work now.

David Chisnall c5d5a98815 Fix use of __atomic_is_lock_free() intrinsic.

2012-04-05 13:13:24 +00:00
Howard Hinnant 7e5b4c9328 Put std::piecewise_construct_t back into the dylib for ABI stability. When clients are in C++11/constexpr mode this will be safely ignored because piecewise_construct is then declared with internal linkage.

2012-04-02 19:23:15 +00:00
Howard Hinnant 788c9979d9 This is an initial commit of constexpr support as proposed by Richard Smith. This by no means completes constexpr support. Indeed, it hardly scratches the surface. All it does is lay the foundation in <__config> and changes those few places in the library that are already using that foundation.

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 cb16c68042 It appears that the standard accidentally removed the default constructor for error_category. I'm putting it back in. This fixes http://llvm.org/bugs/show_bug.cgi?id=12321.

David Chisnall 04e5ce2bc1 Define _WCHAR_T in solaris/wchar.h. This fixes a bug where Solaris 10 headers
try to define C++ keywords as typedefs (fixed in Solaris 11).

2012-02-29 13:17:28 +00:00
David Chisnall 14c25b80e9 Solaris port. Currently sees around 200 test failures, mostly related to
Solaris not providing some of the locales that the test suite uses.

Note: This depends on an xlocale (partial) implementation for Solaris and a
couple of fixed standard headers.  These will be committed to a branch later
today.

Howard Hinnant 9ffe10106e 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.

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 2aa9a38b67 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.

2012-02-15 18:08:09 +00:00
Howard Hinnant 425e44d192 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.

2012-01-10 15:15:47 +00:00
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.
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.
