* Simplify & speed up function callingLars Knoll2013-11-091-1/+2
| | | | | | | | | Get rid of the SimpleCallContext, instead simply use the CallContext data structure, but don't initialize the unused variables. Change-Id: I11b311986da180c62c815b516a2c55844156d0ab Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Refactor marking GC'ed objectsLars Knoll2013-11-051-1/+1
| | | | | | | | | | | Don't use recursive function calls anymore. Instead, push marked objects onto the JS stack, and then pop them off when their children are being marked. Should reduce stack memory usage, and improves performance by ~5%. Change-Id: I2d37d97579144fcba87ec8e9fd545dd220c01fbb Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Initial support for resolving meta-property access for the scope and context ↵Simon Hausmann2013-10-311-4/+10
| | | | | | | | | | | | | | | | | 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 Hausmann2013-10-291-2/+11
| | | | | | | | | | | | | | | | | 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.

* Add support CompositeSingleton to the new V4 compiler.v5.2.0-beta1Antti Piira2013-10-211-2/+6
| | | | | | | | | | | | | | | | | Implements QQmlCodeGenerator::visit(AST::UiPragma *) to process any pragma statements in a QML file for the new V4 compiler approach. Only pragma Singleton is supported, others will generate errors. Also adds necessary hooks to treat types as Singletons. Basic functionality is working, but three of the QML Singleton unit tests fail. Some of them are dependent on other language capabilities that seem to have problems. In addition removes unnecessary toString() call in the equivalent visit(AST::UiPragma *) function of the old parser.

* Qml JavaScript code generation cleanupsSimon Hausmann2013-10-201-1/+1
| | | | | | | | | | | | | | | * Run the binding expressions, functions and signal handlers through the V4 codegen _per_ component, and run the isel at the end for the entire file. We need to do per-component codegen because we want to set up the correct id and object scopes, which are different for the root component and anonymous components. * Changed V4IR::Module to allow for the concept of "qml modules" where there is no root function defined. This is a logical consequence of running v4 codegen multiple times with different input but the same V4IR::Module.

* Fix destruction of QV4::CompiledData::CompilationUnit objectsSimon Hausmann2013-09-201-0/+1
| | | | | | | | | | | Now that we store them per QML file, they live in the type cache and can outlive the engine. Therefore the engine needs to free to unlink any remaining units upon destruction. This needs to be done after the "death" of the memory manager, which is likely to sweep away any function objects that also hold a reference to the compilation units.

| | | | | | | | | | | | | | | | | | | This implements support for "font.pixelSize: 24" for example. The representation in the compile data structure is so that font.pixelSize is short-hand for font { pixelSize: 24 } which means that inside the braces is a complete object initializer. For that initializer we create a dedicated CompiledData::Object, which however has its type name empty. When populating the outer instance then, the "font" property is read as QQmlValueType (a QObject) and instead of creating a new QObject we use that value type as instance to run the rest of the QML object initializer (everything in braces).

* Temporarily collect a map of all functions in the engineSimon Hausmann2013-09-021-1/+1
| | | | | | | | | | | | | | | | At the moment we collect a lot of compilation units (one per binding expression!), which for long running QML accumulates and creates a horrible performance when trying to retrieve back traces. There is work in progress to reduces the number of units down to one per QML file, and then the fixed sorted QVector might proof to be a more efficient data structure for the lookups. But until that code lands, this patch proposes to use a QMap instead for the time being, that tracks all functions. This brings down the qtquickcontrols auto-test run from 2.5 minutes to just under a minute on my machine.
