bf1898e2e6 Added a workaround for clang 3.4 bug: the compiler does not implement __atomic intrinsics even though it defines __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16 macro. 2014-03-15 16:11:03 +04:00

7b13e9cd24 Reworked capabilities definition. For all platforms, added BOOST_ATOMIC_INTn_LOCK_FREE macros that define the support for fixed sized integers. Other macros are deduced from the new ones, according to the native type sizes. 2014-02-09 16:12:00 +04:00

1ee6311ea4 Silence GCC -Wcast-qual warning 
Use C++ casts instead of C-style casts in order to silence warning about casting away qualifiers.

b8cd09c50b Switched to boost::detail::lightweight_mutex instead of boost::mutex from Boost.Thread to avoid false dependencies on Boost.DateTime, Boost.Chrono and Boost.System. This should hopefully resolve linking problems on MinGW.

9cab8a9ebf Added a generic atomic<> implementation based on the new __atomic intrinsics available in gcc 4.7 and clang 3.2. The new implementation adds support for 128-bit atomic. Other implementations updated to employ new macros in Boost.Config for defaulted and deleted functions (this is not complete yet). Fixed padding for the lock pool. Initializing constructor for atomic<> made explicit to avoid ambiguities of different overloads of operator=.

f9c4249c8e 1. Fixed compilation with MSVC 2003. 
2. Fixed incorrect reinterpret_casts in constexpr constructors that could result in buffer overruns. The initializing constructors for non-integral atomics are not constexpr yet because memcpy must be used inside.
3. Made atomic_flag default constructors constexpr. This is not by the standard but we do not implement ATOMIC_FLAG_INIT yet, so the default constructor is needed and it should be constexpr when possible.
4. Fixed a few syntax errors and cleaned up the code a bit.
5. Moved operator value_type() to the interface class in order not to duplicate it in base_atomic specializations.
6. The return type of operator=() changed to follow the standard.
