* Remove setVTable calls in performance critical areasLars Knoll2013-12-041-9/+6
| | | | | | | | | | 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 Knoll2013-12-041-2/+3
| | | | | | | | 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>
* Add a static toArrayIndex() method to QV4::StringLars Knoll2013-12-041-3/+9
| | | | | | | | This avoids a hack in QV4::Codegen where we created a V4::String on the stack to convert to an array index. Change-Id: I9a88d45817bbcde52a4037a52fbae299b8c9cb1a Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Speedup JS instanceof operatorLars Knoll2013-12-041-1/+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 Knoll2013-11-051-3/+3
| | | | | | | | | | | 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>
* Better way of handling string additionsLars Knoll2013-11-041-11/+18
| | | | | | | | | | | The old algorithm still had some quadratic behavior when adding strings in a loop. This fixes is by keeping track of the longest substring used, as well as the length of the string. If the length is larger then twice the length of the longest substring, we simplify the string.

* Optimize string additionsLars Knoll2013-10-311-9/+68
| | | | | | | | | | | | | QV4::String can now either hold a pointer to a QStringData, or a pair of pointers to a left and right string. This reduces the overhead of an addition to allocating a new GC'ed object. To avoid huge chains of linked strings, we use a depth counter, and flatten the string once the depth reaches 16.

| | | | | | | | | | | | | * 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.
