* Move the vtable pointer from the object to the internal classLars Knoll2013-12-041-3/+46
| | | | | | | | This saves one pointer per object, and willmake other optimizations easier in the future. Change-Id: I1324cad31998896b5dc76af3c8a7ee9d86283bfe Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Greatly reduce memory consumed by QQmlEngine instancesLars Knoll2013-11-191-21/+18
| | | | | | | | | | | | | | | | Due to a inefficiency in our InternalClass implementation, we were not sharing the string and attribute table between internal class instances. This was extremely inefficient with the Qt object, as it created around 1000 internal classes with large string and property tables. With the patch these tables are now shared. Reduces memory consumption of a QQmlEngine instance from around 6.5M to a couple of 100k. Change-Id: Ib763f31deca0808c000ac2c30aa0b05e806bda40 Reviewed-by: Erik Verbruggen <erik.verbruggen@digia.com>
* Refactor marking GC'ed objectsLars Knoll2013-11-051-1/+1
| | | | | | | | | | | Don't use recursive function calls anymore. Instead, push marked objects onto the JS stack, and then pop them off when their children are being marked. Should reduce stack memory usage, and improves performance by ~5%. Change-Id: I2d37d97579144fcba87ec8e9fd545dd220c01fbb Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Cleanup calls to Object::setPrototype()Lars Knoll2013-09-021-4/+9
| | | | | | | | 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 Knoll2013-09-021-4/+21
| | | | | | | | | | | | | 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>
