* Add a set of atomics based on C++11's std::atomicThiago Macieira2012-01-281-1/+2
| | | | | | | | | | | | | | | | | | | | | The C++11 std::atomic type is very close to our API, to the point one has to wonder if the committe was inspired by it. It provides all of the memory semantics that Qt requires and more, plus some compare-and-swap operations that we don't use. The idea of returning the actual value in the event of a failed compare-and-swap is actually quite good, as often we'll retry with it. We just couldn't come up with a good name (fetchAndTestAndSet?). The C++11 atomics require that the compiler support constexpr as well, since std::atomic itself isn't required by the standard to be trivially-constructible (in fact, it has a constexpr constructor in the standard). For that reason, we need constexpr so we can add a constructor to QBasicAtomic too.

* Add a set of atomics based on GCC intrinsicsThiago Macieira2012-01-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | With this implementation, we can have Qt run on any architecture that GCC supports without having to write specialised code. However, on some architectures, the code that GCC generates is not optimal: it uses locking on ARMv5 and it's always fully-ordered. For that reason, it appears after the Qt native assembly implementations (it's a fallback, not an override). Since they all have fully-ordered memory semantics, we define only the xxxRelaxed functions. The exception is __sync_lock_and_test, which has acquire semantics, so we need to define the Release and Ordered versions too. On some architectures, GCC can support atomics on types different than 32-bit and pointer-sized (like x86, x86-64, ARM and even MIPS). However, there's no standardised way of telling: GCC seems to define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_{1,2,4,8} if those operations are present, but I couldn't find it on the ARM compiler (it was there for i386, x86-64, IA-64 and MIPS).

* Remove the 'macosx' archBradley T. Hughes2012-01-261-1/+2
| | | | | | | | | | | | | The new atomic implementation chooses which header to include based on what #define's are set by the compiler (i.e. __x86_64__ or __i386__). Because of this, the qatomic_macosx.h header isn't used anymore. This also means that the configure script does not need to use or look for this file anymore, it should just use the normal uname -m detection.
