* Get rid of qv4value_inl_p.h and replace it by qv4typedvalue_p.hLars Knoll2015-04-241-1/+1
| | | | | | | | This is a cleaner separation and further reduces include dependencies in the definitions of our basic data structured. Change-Id: I18aa86cdea0c0dfbc16075d4d617af97e638811e Reviewed-by: Simon Hausmann <simon.hausmann@theqtcompany.com>
* Speed up property binding initialization on object creationSimon Hausmann2015-04-211-0/+10
| | | | | | | | | | Avoid repeated string hashing and lookups in the property cache in order to retrieve the property details when initializing literal and script bindings. Instead we now cache the property data at type validation time, similar to how the property data was encoded in the VME instructions in the old engine.

* Fix run-time string handling with regards to the new heapSimon Hausmann2014-11-211-14/+9
| | | | | | | | | | | | | | | | | Changed runtimeStrings to be an array of Heap::String pointers instead of indirect String pointers. Later that member along with other GC related members will go into a managed subclass. Meanwhile the generated code no more loads String pointers directly but just passes the index into the run-time strings to the run-time functions, which in turn will load the heap string into a scoped string. Also replaced the template<T> Value::operator=(T *m) with a non-template overload that takes a Managed *, in order to help the compiler choose the non-template operator=(Heap::Base *) overload. This allows removing a bunch of Value::fromHeapObject calls. Change-Id: I20415c0549d33cca6813441a2495976b66d4c00e Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* v4: Enable primitive conversation to QQmlScriptString in javascriptSebastian Sauer2014-08-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This makes following QML-code proper working: ParentChange { x: 0 Component.onCompleted: x = 10 } where x is a QQmlScriptString. Before this patch an error-message would be thrown that the bool/int/string/etc cannot be converted to a QQmlScriptString. With the patch primitive types including null and undefined are proper converted to a QQmlScriptString. The patch ignores (as in not implements) function/binding assignment. Unfortunately since commit aa25ad8d5f4 its not possible any longer to instanciate QQmlScriptString what means there is otherwise no (easy) way to inject a QQmlScriptString from within Javascript.
