From c9e6251cc8dfcf002f64b07e48dd68b7edd3f630 Mon Sep 17 00:00:00 2001 From: Simon Hausmann Date: Wed, 2 Jan 2019 16:09:56 +0100 Subject: Implement dummy QML lookups for "global" variables 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).
