* Doc: Prepare for building modular QtCore docs.Casper van Donderen2012-04-191-2/+2
| | | | | | | | | | | | This change fixes most qdoc errors in QtCore. There are about 900 left. The main thing this change does is moving documentation from qtcore from /doc/src to /src/corelib/doc. Other issues resolved are mis-use of qdoc commands.

* Remove HP PA-RISC atomic implementation.Bradley T. Hughes2012-02-131-12/+0
| | | | | | | | | | | This architecture is obsolete and discontinued.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).

* Remove "All rights reserved" line from license headers.Jason McDonald2012-01-301-1/+1
| | | | | | | | | | As in the past, to avoid rewriting various autotests that contain line-number information, an extra blank line has been inserted at the end of the license text to ensure that this commit does not change the total number of lines in the license header.

* Add the new QBasicAtomicXXX implementation - no backends yetThiago Macieira2012-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Remove cast and assignment operators from QAtomicInt and QAtomicPointerBradley T. Hughes2011-12-021-68/+0
| | | | | | | | | | | | | | | | | | | This is a source incompatible change. There is concern that the convenience of the implicit cast and assignment operators can lead to misuse. Several commits have already been done that remove excess use of the implicit cast, which is a *volatile* read every time it's used. Users of the QAtomic* API should have to think about when they are loading the value, and if they do or don't need the acquire memory barrier on load. The code that people would write using this API is meant to be multi-threaded, concurrent, and correct. The API should not allow them to inadvertently, possibly unknowingly, shoot themselves in the foot.
