* Extend the QML bootstrap library by the IR buildersSimon Hausmann2014-04-231-3/+8
| | | | | | | | | | | | | This is among other things needed to fix the qml import scanner to detect dependencies from .js files correctly. The patch also fixes the use of Q_QML_EXPORT towards Q_QML_PRIVATE_EXPORT where appropriate and corrects the wrong include path for the double conversion code to actually be relative to the file it is included from. This worked by accident because of other include paths present in the build. Change-Id: I338583dad2f76300819af8ab0dae8e5724c84430 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Make the Ref classes not template basedLars Knoll2014-02-071-0/+2
| | | | | | | | | | Move to a class hierarchy that mirrors the main classes. This will allow moving functionality over into the Ref classes, as the current Managed classes become mainly something that holds the data. This is required to make objects movable by the GC.

* Remove an unused constructorLars Knoll2014-02-051-4/+0
| | | | | | | | | | Fortunately we don't use this constructor anymore. This also allows us to fix the assert in qv4managed. Now we finally enforce that every managed object must have an internal class and a vtable. Change-Id: Idf9081c20633b44b79970fec4cc4d1ec5e6a6f7c Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Disentangle some includesLars Knoll2014-01-311-2/+2
| | | | | | | | | ScopedValue should require less dependencies. Hopefully we can then move it together with the main class definition at some point (ie. move ScopedValue int qv4value_p.h; similar for the other types).

* Rework array handling for JS objectsLars Knoll2014-01-091-0/+2
| | | | | | | | | 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>
* Move Managed::type and some flags into the vtableLars Knoll2014-01-031-1/+6
| | | | | | | | | | | | | 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 Knoll2013-12-041-1/+1
| | | | | | | | | | 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.

* Add a static toArrayIndex() method to QV4::StringLars Knoll2013-12-041-0/+2
| | | | | | | | 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>
* 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>
* Better way of handling string additionsLars Knoll2013-11-041-12/+11
| | | | | | | | | | | 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/+41
| | | | | | | | | | | | | 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.
