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

* Fix run-time string handling with regards to the new heapSimon Hausmann2014-11-211-20/+18
| | | | | | | | | | | | | | | | | Changed runtimeStrings to be an array of Heap::String pointers instead of indirect String pointers. Later that member along with other GC related members will go into a managed subclass. Meanwhile the generated code no more loads String pointers directly but just passes the index into the run-time strings to the run-time functions, which in turn will load the heap string into a scoped string. Also replaced the template<T> Value::operator=(T *m) with a non-template overload that takes a Managed *, in order to help the compiler choose the non-template operator=(Heap::Base *) overload. This allows removing a bunch of Value::fromHeapObject calls. Change-Id: I20415c0549d33cca6813441a2495976b66d4c00e Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* Simplify our breakpoint handlingLars Knoll2014-03-071-2/+2
| | | | | | | | | | | | | | | | | 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>

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.
