* Extend the QML bootstrap library by the IR buildersSimon Hausmann2014-04-231-2/+14
| | | | | | | | | | | | | This is among other things needed to fix the qml import scanner to detect dependencies from .js files correctly. The patch also fixes the use of Q_QML_EXPORT towards Q_QML_PRIVATE_EXPORT where appropriate and corrects the wrong include path for the double conversion code to actually be relative to the file it is included from. This worked by accident because of other include paths present in the build. Change-Id: I338583dad2f76300819af8ab0dae8e5724c84430 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* Clean up object literal handling with integral indicesSimon Hausmann2014-02-241-3/+1
| | | | | | | | | | | | | | | | | | | | | * Object literals with array indices are now created with one run-time call, instead of an initial one for non-integral keys followed by sub-sequent define_builtin_property calls. * Cleaned up propert name retrieval. Instead of using a visitor, it's easier to define a virtual method on the PropertyName type. The visitor doesn't buy us much as it's not possible to recurse within property names, and this way we can use it also from the function scanner to correctly determine the number of arguments needed for object literal initalizations. * Similarly the duplicated/common name member for all property assignments has been moved into PropertyName, for convenient access without AST casts. * Removed now unused builtin_define_property/settergetter functions from IR, run-time and moth.

* Fix property dependency generation for accelerated QML QObject propertiesSimon Hausmann2013-11-121-1/+1
| | | | | | | | | | | | | | The previous approach of collecting the dependencies through an IR visitor doesn't work, because it relies on a fixed structure - for example MEMBER(NAME, prop) - which we can't guarantee (it's usually MEMBER(TEMP, prop)). But it turns out that we can only pre-calculate dependencies for context, scope or id properties, so we can do that right away in the QML specific JS codegen, store that information in the IR function and use it from there in the data structure generator as well as in the isel as a parameter to getQObjectProperty to tell the run-time whether capture is required or not.

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.

| | | | | | | | | | | | | | | | | 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.
