* Optimize String.replace and RegExp.execLars Knoll2013-09-021-0/+15
| | | | | | | This speeds up the v8 regexp benchmark by a factor 2.5 :) Change-Id: Ibd6b18ee28181aa712429cbec4598984e0c69820 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Cleanup calls to Object::setPrototype()Lars Knoll2013-09-021-50/+27
| | | | | | | | Rather use the correct internalClass directly when constructing the objects. Change-Id: I8e916f1ce8f83d291c08ca6332fe85b1f57b90b5 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Move prototype pointer into QV4::InternalClassLars Knoll2013-09-021-64/+52
| | | | | | | | | | | | | 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>

* move methods to create a new context into the ExecutionContext classLars Knoll2013-09-021-29/+0
| | | | | | | | This avoids one indirection when calling the methods and cleans up the engine a bit. Change-Id: I426f41e23f6a7262af95b9807b00920530fef642 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Temporarily collect a map of all functions in the engineSimon Hausmann2013-09-021-0/+14
| | | | | | | | | | | | | | | | 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.
