| | | | | | | | | | | | | Add a Returned<T> that we can return instead of raw pointers to Managed objects. Start using the Returned<T> for a few methods. Also clean up all our classes to use the Q_MANAGED macro instead of manually defining their vtable.

| | | | | | | | | | | | | The prototype is actually the same for most objects. By moving it into the internal class, we can save 8 bytes per object, as well as allowing for some future optimizations. Also fix a bug in the implementation of the Error prototype objects. Change-Id: I4d4b641055f644a9b088f27be34bfdb0446279b7 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Temporarily collect a map of all functions in the engineSimon Hausmann2013-09-021-0/+1
| | | | | | | | | | | | | | | | At the moment we collect a lot of compilation units (one per binding expression!), which for long running QML accumulates and creates a horrible performance when trying to retrieve back traces. There is work in progress to reduces the number of units down to one per QML file, and then the fixed sorted QVector might proof to be a more efficient data structure for the lookups. But until that code lands, this patch proposes to use a QMap instead for the time being, that tracks all functions. This brings down the qtquickcontrols auto-test run from 2.5 minutes to just under a minute on my machine.
