* Mark all qtbase headers that aren't cleanThiago Macieira2013-03-031-0/+1
| | | | | | | | | | | | | | | | QtCore has a few headers that, though public, aren't meant to be included directly. Those are the atomic headers, the three _impl.h headers and qt_windows.h. QtGui includes two OpenGL headers that don't compile on their own. Other libraries should not have headers like that (but they do, something we need to fix eventually).

* Remove qatomic_arch.hBradley T. Hughes2012-02-131-3/+1
| | | | | | | | | | | | Make qbasicatomic.h include the OS/compiler/processor dependent implementation. For implementations that have not yet been ported to declare a QAtomicOps, they need to #include <QtCore/qoldbasicatomic.h>, and the new QBasicAtomicInteger and QBasicAtomicPointer should not be declared.

| | | | | | | | | | | This architecture is obsolete and discontinued. Support for PA-RISC can be re-added if needed, but it would be preferred to use the GCC intrinsic support from qatomic_gcc.h (on Linux/HPPA, for example).

* Silence syncqt warnings for atomic implementation headersBradley T. Hughes2012-02-061-0/+4
| | | | | | | | | | Most of these headers are either forwarding headers, or we explicitly stop syncqt so that it doesn't generate class includes for the atomic implementation. Either way, syncqt doesn't see the QT_END_* (and sometimes not QT_BEGIN_*), which this commit fixes.

* Port the bootstrap atomics to the new QBasicAtomic architectureThiago Macieira2012-01-241-4/+0
| | | | | | | | | | | | | The code is now much simpler and much more complete. Now the bootstrap atomics (which aren't atomic at all) contain the full set of operations. The only integer supported is int, but all others would work too. Change-Id: Id99f07818f9da059c4ff02520f9cbf2d1a71a514 Reviewed-by: Bradley T.

* Add the new QBasicAtomicXXX implementation - no backends yetThiago Macieira2012-01-201-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new implementation is API- and ABI-compatible with the old implementation, provided that QBasicAtomicInt isn't used as an argument in a function call or the return value: now, QBasicAtomicInt is a typedef to QBasicAtomicInteger<int>. The new design is based on CRTP: the QGenericAtomicOps template class takes as a template parameter the derived class itself. This way, we implement a "poor man's virtual" without a virtual table and everything is inline. QGenericAtomicOps implements most of the atomics code that is repeated in many classes all over: * Acquire semantics are obtained by placing an acquire barrier after the Relaxed operation * Release semantics are obtained by placing a release barrier before the Relaxed operation * Ordered semantics are obtained by placing an ordered barrier before the Relaxed operation (either way would be fine) * fetchAndStoreRelaxed and fetchAndAddRelaxed are implemented on top of testAndSetRelaxed * ref and deref are implemented on top of fetchAndAddRelaxed It also adds load, loadAcquire, store and storeRelease: the default implementations of loadAcquire and storeRelease operate on a volatile variable and add barriers. There are no direct operators for accessing the value. Each architecture-specific implementation can override any of the functions or the memory barrier functions. It must implement at least the testAndSetRelaxed function. In addition, by specialising one template class, the implementations can allow QBasicAtomicInteger for additional types (of different sizes). At the very least, int, unsigned and pointers must be supported. Change-Id: I6da647e225bb330d3cfc16f84d0e7849dff85ec7 Reviewed-by: Bradley T. Hughes <bradley.hughes@nokia.com>
