* Rework array handling for JS objectsLars Knoll2014-01-091-5/+7
| | | | | | | | | Split up ArrayData into two classes, one for regular arrays, one for sparse arrays and cleanly separate the two cases. Only create array data on demand. Change-Id: I9ca8d0b53592174f213ba0f20caf93e77dba690a Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Fix compiler warning about wrong reinterpret_castLars Knoll2014-01-031-4/+4
| | | | | | | | | No need to use reinterpret_cast's in the type checking for the Managed casting. A static cast works just as well (as it's actually used two lines further down). Change-Id: Ie531098eddddda7e9f151eaedc136cbeab14f473 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Move Managed::type and some flags into the vtableLars Knoll2014-01-031-19/+79
| | | | | | | | | | | | | 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.

* Fix data layout of Managed classLars Knoll2013-12-051-4/+4
| | | | | | | | The internal class should really be the first member. The flags should go away over time. Change-Id: Id2373a438e2af63a55704819c9dd5569c3895080 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Encapsulate the current context and fix it's usageLars Knoll2013-12-041-1/+1
| | | | | | | | | | | Encapsulate accesses to the current context, and rework the way we push and pop this context from the context stack. Largely a cleanup, but simplifies the code in the long term Change-Id: I409e378490d0ab027be6a4c01a4031b2ea35c51d Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Remove setVTable calls in performance critical areasLars Knoll2013-12-041-1/+4
| | | | | | | | | | 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.

* Move the vtable pointer from the object to the internal classLars Knoll2013-12-041-12/+14
| | | | | | | | This saves one pointer per object, and willmake other optimizations easier in the future. Change-Id: I1324cad31998896b5dc76af3c8a7ee9d86283bfe Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Speedup JS instanceof operatorLars Knoll2013-12-041-5/+0
| | | | | | | | Cache the prototype of the functionobject, and inline hasInstance. This removes a vtbl method and speeds things up quite a bit. Change-Id: Ic68f301f7e09763d445a98bffa2cd201303f902e Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Refactor marking GC'ed objectsLars Knoll2013-11-051-8/+2
| | | | | | | | | | | 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>
* inline get_element callsLars Knoll2013-10-141-12/+16
| | | | | | | | | | | Inline calls to get_element if the base is an object with a simple array structure, and the index is an integer number. Implemented for 64bit only for now, saves ~25% on crypto.js Change-Id: I3e34a6409169d90d3937f62264707d52a6c2f9f7 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Refactor our NaN boxing to be more efficientLars Knoll2013-09-181-4/+14
| | | | | | | | | | | | | * Use a unified way to store all Managed objects inside a Value, instead of distinguishing between strings and other objects. * On 64 bit we store pointers as pointers, so accessing them through Scoped<> objects is cheap. This implies that doubles are now stored in a mangled form (xor'ed with a mask). Change-Id: I582e0fb167a62c0c527c6bfa3452550e37944069 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
