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.

This directory contains autotests and benchmarks based on Qt Test. In order to run the autotests reliably, you need to configure a desktop to match the test environment that these tests are written for. Linux X11: * The user must be logged in to an active desktop; you can't run the autotests without a valid DISPLAY that allows X11 connections. * The tests are run against a KDE3 or KDE4 desktop. * Window manager uses "click to focus", and not "focus follows mouse". Many tests move the mouse cursor around and expect this to not affect focus and activation. * Disable "click to activate", i.e., when a window is opened, the window manager should automatically activate it (give it input focus) and not wait for the user to click the window.
