* Fixes to Error objectsLars Knoll2015-09-221-23/+1
| | | | | | | | | | | | | Move the name and message property into the prototype as per JS spec. Only define the message property in the object itself if the value used for construction is not undefined. In addition, clean up creation of the objects and centralize it in a few template methods.

* Move vtable out of internalClassLars Knoll2015-01-201-8/+3
| | | | | | | | | | | | | | | | We can move the internalClass to Object later on, and such save having the internalClass on lots of Heap objects. This commit basically adds and starts making use of a new vtable pointer in Heap::Base. In addition, the construction methods in the memory manager now automatically setup the correct vtable. Removing the vtable code from InternalClass and moving it into Object will come in a separate commit Change-Id: If49e8d73c769bf65bf47fe4dbf8b9546c8019dbc Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Fix Managed::as<>() methodLars Knoll2014-07-221-0/+1
| | | | | | | | | | | | | | | The as<> casting method was not doing the right thing in 100% of the cases. It only checked if the object in question was exactly of the type being asked for. It however didn't check if the object was derived from the type. This commit fixes this by adding a parent chain to the vtables, that is then being used to check this safely at runtime.

* Avoid side effects when en exception has been thrown.Lars Knoll2013-10-291-5/+4
| | | | | | | | | | | | | | We don't want to check for exceptions after every single line on our runtime methods. A better way to handle this is to add the check in all methods that have direct side effects (as e.g. writing to a property of the JS stack). We also need to return whereever we throw an exception. To simplify the code, ExecutionContext::throwXxx methods now return a ReturnedValue (always undefined) for convenience.
