* Fix Managed::as<>() methodLars Knoll2014-07-221-1/+1
| | | | | | | | | | | | | | | The as<> casting method was not doing the right thing in 100% of the cases. It only checked if the object in question was exactly of the type being asked for. It however didn't check if the object was derived from the type. This commit fixes this by adding a parent chain to the vtables, that is then being used to check this safely at runtime.

* Extend the QML bootstrap library by the IR buildersSimon Hausmann2014-04-231-4/+12
| | | | | | | | | | | | | This is among other things needed to fix the qml import scanner to detect dependencies from .js files correctly. The patch also fixes the use of Q_QML_EXPORT towards Q_QML_PRIVATE_EXPORT where appropriate and corrects the wrong include path for the double conversion code to actually be relative to the file it is included from. This worked by accident because of other include paths present in the build. Change-Id: I338583dad2f76300819af8ab0dae8e5724c84430 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

| | | | | | | | | | | | | Move the type flag into the vtable to free up these bits in the Managed class, and not have to set them at object construction time. As we often need to know whether a Managed object is a Object, FunctionObject or String, add some bitflags to test for these to the vtable.

* Optimize string additionsLars Knoll2013-10-311-9/+68
| | | | | | | | | | | | | QV4::String can now either hold a pointer to a QStringData, or a pair of pointers to a left and right string. This reduces the overhead of an addition to allocating a new GC'ed object. To avoid huge chains of linked strings, we use a depth counter, and flatten the string once the depth reaches 16.
