* Add missing qmlRegisterExtendedUncreatableType variantKevin Ottens2017-02-172-0/+41
| | | | | | | | | | | | | We need another qmlRegisterExtendedUncreatableType allowing to pass the metaObjectRevision as third parameter. Otherwise extended uncreatable types can't use for instance REVISION in their properties. This is missing for some of the Qt 3D types for which we are cleaning up the versioning for 5.9.0 and which fall in this category.

* Directly load already known metaproperties in QV4QObjectWrapperUlf Hermann2017-02-151-8/+18
| | | | | | | | | | | | | A method and a property can have the same name in a QObject. This is not directly expressible in a JS object, but when iterating the properties of a wrapped QObject we should not look them up by name as we might find the wrong one this way. However, as we already know what we are looking for, there is no need for any further searching anyway.

| | | | | | | | | | | | | | | | | QSignalMapper ought to be deprecated soon. It simplifies the code, too. There is still one use in QQuickGenericShaderEffect which is a bit complicated to get rid of. A very similar use of QSignalMapper was in use in QQuickOpenGLShaderEffectCommon but was removed in commit 8c745d80, the same should be done for QQuickGenericShaderEffect.

| | | | | | | | | | | | | | | | | | | | | | | | | Even when the C++ target is not ARMv7 we want to include it in order to be able to generate QML cache files with code ahead of time. This requires a few changes: * The Jump classes need to move from the AbstractMacroAssembler super-class into the concrete assembler sub-class, in order to use it in specializations. * Some of the template specializations in LinkBuffer for example or for platform dependent operations need to be pre-processor enabled when bootstrapping * The generic loadPtr/addPtr etc. functions need to move to the concrete assemblers to be able to call the correct 32-bit or 64-bit variations. * We need to force what looks like a loss of precision to the compiler in the 32-bit ARMv7 linking code when linking jumps. Finally then we can explicitly instantiate at least QV4::JIT::Assembler for ARMv7 when bootstrapping. Currently only on x86-64 hosts, but that is a temporary limitation.
