* QML: Optimize QObject method callsUlf Hermann2022-09-201-4/+6
| | | | | | | | | | | | | | | | | | | | | | So far, for each method call we had to allocate a new QObjectMethod as we didn't have any lookup to cache the methods. Introduce a new lookup for that and use it for all QObject methods. Since QObjectMethod contains a pointer to the concrete QObject the method was retrieved from, some more care has to be taken: If we are going to call the method right away, we don't need the object since we always have a thisObject and any further retrieval of the same method will result in a call again. This enables us to cache the method for any instance of the same class. When storing the method elsewhere, though, we need to hold on to the object since you can defer the call or connect a handler to a signal or similar. For such operations we do need the object. We can still optimize a bit by re-using the method cache we build the first time around.

* Implement dummy QML lookups for "global" variablesSimon Hausmann2019-03-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When resolving names in the context of QML bindings, we now direct runtime access to QQmlContextWrapper::resolveQmlPropertyLookupGetter. At the moment this does basically the same as Runtime::method_loadName, which we called earlier. However this now provides the opportunity to optimize lookups in the QML context in a central place. When performing a call on a scope or context object property, we also did not use a CallName() instruction - which would have gotten the thisObject wrong - but instead we use a dedicated CallScopeObjectProperty and CallContextObjectProperty instruction. These rely on identifying these properties at compile time, which goes away with lookups (and also doesn't work when using ahead-of-time compilation). Therefore the qml context property lookup is using a getPropertyAndBase style signature and Runtime::method_callQmlContextPropertyLookup uses that. For the tests to pass, some error expectations need adjusting. In particular the compile-time detection of write attempts to id objects is now delayed to the run-time. The old code path is still there and will be removed separately in the next commit (as it is massive).

* Reduce memory usage caused by strings with AOT cache filesSimon Hausmann2018-07-311-0/+1
| | | | | | | | | | | | | | | | For AOT loaded cache files, the CompiledData::Unit we produce is ephemeral by design. That same applies to the strings, where we don't really need to write out a new string table but we might as well just keep the QStringList around. That avoids copying all the string data and saves another 21K RAM with the gallery. It might even save a little more if some of the new strings are truly shared via implicit QString sharing. Also their "extraction" via stringAt(index) becomes as fast as for the strings that come from mmap'ed memory - with no copying involved.

* Optimize memory consumption of ahead-of-time compile cache filesSimon Hausmann2018-07-311-2/+5
