* Add ability to retrieve and use the QmlContext from our generated codeLars Knoll2015-08-101-0/+6
| | | | | | | | | | | | | | Our generated code (JIT and interpreter) should operate on the QML context to retrieve QML related things. That's better than operating on 4 different temps. So this commit introduces the QML context as a temp in the code we generate for QML. The next commits will move things over to use that context with specialized runtime methods instead of using generic subscript/get calls on the different subobjects.

* Simplify our breakpoint handlingLars Knoll2014-03-071-1/+1
| | | | | | | | | | | | | | | | | Only store a Hash of break points in the debugger, instead of the involved logic that currently adds and removes break points. Add the current line number to the Debug statements in the interpreter, and pass them on to the debugger for checking whether we should really break. This adds a slight additional overhead to running inside the debugger, but greatly simplifies the logic and doesn't require modifying the bytecode anymore. This in turn opens up the possibility to run the debugger on JIT generated code later on. Change-Id: If2a3ae8f8d08b69a3a704cbbe0a84000f917a32e Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Clean up object literal handling with integral indicesSimon Hausmann2014-02-241-17/+2
| | | | | | | | | | | | | | | | | | | | | * 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.

This still allows interrupting the JS execution at any time (as we can't loop inside a basic block), and single stepping through lines. But it has no overhead when the debugger is not running and a lot less when it is running.

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.
