* Clean-up QRgba64 constructorsAllan Sandfeld Jensen2017-03-131-13/+1
| | | | | | | | | | | | | | | | | We can add basic constructors now on all supported platforms, and can make initialization consistent on all platforms, choosing undefined as the default. Note this changes behavior on gcc and clang builds, but is consistent with pre-c++11 gcc and clang builds and with msvc. [ChangeLog][QtGui][QRgba64] The default constructor on Clang and GCC builds now no longer initializes with 0s, but leaves the value uninitialized. This is consistent with MSVC behavior and pre-C++11 behavior of GCC and Clang. Change-Id: Ib0e3d7f4274a13a768db62931b67877e3898945e Reviewed-by: Marc Mutz <marc.mutz@kdab.com>
* Add qtguiglobal.h and qtguiglobal_p.hLars Knoll2016-07-031-1/+1
| | | | | | | | | | | | | | | | | | | | The new modular configuration system requires one global header per module, that is included by all other files in this module. A similar scheme and naming convention is already being used for many other modules (e.g. printsupport, qml, quick). That header will later on #include the configuration file for Qt Gui. For now it defines the Q_GUI_EXPORT macro for this library. In addition, add a private global header, qtguiglobal_p.h, that can later on include the private config header for Qt Gui for things we don't want to export to the world.

* Remove type punning from QRgba64.Erik Verbruggen2015-08-111-49/+68
| | | | | | | | | | | | In C++, type punning with a union is not allowed. It will result in compiler defined behavior at best, and undefined behavior at worst. Specifically, if QRgba64 is passed to a function by value, the different members of a struct might be passed in separate registers. This means that any write to the quint64 might not blank out the values of the struct whenever the compiler looses track with TBAA.
