* Split ManagedVTable into two classesLars Knoll2014-01-211-4/+4
| | | | | | | | Keep the basic methods in ManagedVTable, but have the Object related stuff in an ObjectVTable class. Change-Id: I9b068acf3caef813686227b8d935e7df1a7d1a6e Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Add support for accelerated property access to QML types and namespace supportSimon Hausmann2013-11-281-2/+4
| | | | | | | | | | | * Resolve lookups in namespaces at compile time and instruct the SSA optimizer to eliminate reads from the namespace (QQmlTypeWrapper) if possible. For example access to attached properties of types (i.e. MyNameSpace.ListView.isCurrentItem) requires neither reading the namespace nor the type. * Add support for accelerated lookup of attached properties Change-Id: Ib0b66404ed7e70e1d4a46a1ac8218743a4cc8608 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Initial support for accelerated property access to QML singletons and enumsSimon Hausmann2013-11-251-0/+19
| | | | | | | | | With this patch we determine the meta-object of singletons, propagate it into the IR and load them separately using a dedicated run-time function. In addition enums in singletons and QML types are resolved at compile time. Change-Id: I01ce1288391b476d1c9af669cb2987a44c885703 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* IR Cleanup, resolve ID objects through array subscriptsSimon Hausmann2013-11-251-1/+57
| | | | | | | | | | | | ...instead of a special MEMBER type. This allows removing the type member from V4IR::Member altogether (and thus unshadow from V4IR::Expr::type). By not requiring the base of a id lookup member expression to be a NAME, we can also speed up repeated id lookups by fetching the id object array wrapper only once per function.

* Speed up lookups of imported scriptsSimon Hausmann2013-10-311-5/+2
| | | | | | | | | | The QQmlContextData stores the JS objects of imported scripts in a QList<PersistentValue>. Instead of indexing into that list, this patch changes ctxt->importedScripts to be a JavaScript array, that in the IR we can index via subscript.

* Initial support for resolving meta-property access for the scope and context ↵Simon Hausmann2013-10-311-4/+21
| | | | | | | | | | | | | | | | | objects at QML compile time This avoids having to do a string lookup for ids and in the import cache at run-time, before we can do a string hash lookup in the property cache. Instead we resolve final properties in the context and scope object at compile time and look them up at run-time using their index instead. The dependencies to these properties are also tracked separately and recorded in the compiled data. This is merely the initial patch. There's a lot left to do, such as having specialized getter and setters for specific property types. Setters are missing altogether right now and will fall back to name lookup.

* Speed up id object lookupsSimon Hausmann2013-10-291-1/+25
| | | | | | | | | | | | | | | | | We can resolve lookups for objects referenced by id at QML compile time and use a run-time helper to extract the id object out of the QML context data by index instead of name. Dependencies to id objects are also tracked at compile time and registered separately before entering the generated function code. The lookup of id objects is encoded in the IR as special member lookups. Members will also then in the future be used to for property lookups in context and scope properties, as well as any other property lookups in QObjects where we can determine the meta-object.

* Avoid side effects when en exception has been thrown.Lars Knoll2013-10-291-2/+6
| | | | | | | | | | | | | | We don't want to check for exceptions after every single line on our runtime methods. A better way to handle this is to add the check in all methods that have direct side effects (as e.g. writing to a property of the JS stack). We also need to return whereever we throw an exception. To simplify the code, ExecutionContext::throwXxx methods now return a ReturnedValue (always undefined) for convenience.
