* Revert "Don't add qmutex_xxx.cpp to SOURCES, as qmutex.cpp #include's them"Oswald Buddenhagen2016-03-071-19/+15
| | | | | | | | | | | This reverts commit 40cbf1927bdd2fa9f531a047d1ba66f68c35d170 - the qmake parser bug this worked around has been fixed. As a side effect, the platform conditionals were simplified.

* Don't add qmutex_xxx.cpp to SOURCES, as qmutex.cpp #include's themThiago Macieira2015-08-061-12/+12
| | | | | | | | | | | | Normally qmake catches the #include and drops the source from SOURCES. But the parser has bugs, so help it by never adding the files. The false: SOURCES += is left so that the sources can be found by Qt Creator.

* winrt: Use native threadingAndrew Knight2014-06-251-0/+5
| | | | | | | | | | | | | | | | | Instead of using std::thread, use the WinRT ThreadPool to manage threads. This allows for setting the scheduling priority, and provides a path to enable XAML integration (which requires Qt run on a background thread). QThread::terminate() is still unsupported, and only the winmain thread can be adopted due to the behavior of the thread pool when creating tasks from the GUI thread. The associated tests are now skipped, and all other QThread tests pass.

* Remove all "old atomic" code from QtThiago Macieira2013-12-101-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The new atomic code was introduced in Qt 5.0. The platforms that did not get ported were announced as deprecated in Qt 5.2. The code is now removed in Qt 5.3. The status for the platform/compiler/OS combinations affected is: * Linux with GCC or Clang: still compiles on all platforms (via qatomic_cxx11.h or qatomic_gcc.h) * INTEGRITY with Green Hills compiler: no longer compiles * Solaris on UltraSPARC, with Sun Studio: no longer compiles * AIX on POWER5 or 6, with IBM Visual Age: no longer compiles (probably did not compile Qt 5.0 either) * VxWorks in kernel mode: no longer compiles [ChangeLog][General] Support for the following platforms has been removed, due to lack of interest in updating support: INTEGRITY, VxWorks, Solaris on UltraSPARC (with the Sun Studio compiler suite), AIX on POWER processors (with IBM Visual Age compiler suite).

* Distinguish between 'mac' and 'macx' qmake scopesTor Arne Vestbø2013-03-051-1/+1
| | | | | | | | | | | | | | The former applies both on Mac OS X and iOS, but 'macx' is specific to Mac OS X. ios.conf and macx.conf now share most of their settings in the common mac.conf. We set the default QMAKE_MAC_SDK before loading mac.conf, so that any overrides in the device config will apply afterwards. This means configure's mkspec parsing will be able to read the QMAKE_MAC_SDK.

* Add the new QBasicAtomicXXX implementation - no backends yetThiago Macieira2012-01-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
