* Fixes for argument objectsLars Knoll2014-01-091-0/+1
| | | | | | | | | Fix a possible infinite recursion, and a corner case where we wouldn't set the correct data when writing to the argument object Change-Id: Ia64b9f62e9b881e24d74e23d96d5eb27805a126f Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Add Object::hasOwnProperty()Lars Knoll2014-01-091-0/+3
| | | | | | | | This allows us to remove more getOwnProperty calls. This will be required later on to extend our array handling. Change-Id: I7b7f5887990cd443accf51891644fdfbb849cf35 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Move Managed::type and some flags into the vtableLars Knoll2014-01-031-6/+9
| | | | | | | | | | | | | Move the type flag into the vtable to free up these bits in the Managed class, and not have to set them at object construction time. As we often need to know whether a Managed object is a Object, FunctionObject or String, add some bitflags to test for these to the vtable.

* Remove setVTable calls in performance critical areasLars Knoll2013-12-041-2/+0
| | | | | | | | | | Remove all the calls to setVTable that were in performance critical parts of the code. This now brings performance back to the level we had with the vtable inlined in the Managed objects.

* Simplify & speed up function callingLars Knoll2013-11-091-4/+4
| | | | | | | | | 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>

* Avoid creating array attributes if possibleLars Knoll2013-10-141-3/+6
| | | | | | | | | | | Holes in arrays should be represented by an empty value, not by creating/setting array attributes. Reason is that the creation is irreversable, and slows down execution.
