| | | | | | | | We don't need it and we don't need to check for V4_BOOTSTRAP in there. Shuffle some includes around to provide everything we do need. Change-Id: I3e75f1c6f9dc518006aabc9dcee21e5153899ac5 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Make JavaScript execution interruptibleUlf Hermann2019-04-301-1/+19
| | | | | | | | | | | Add an atomic isInterrupted flag to BaseEngine and check that in addition to the hasException flag on checkException(). Add some more exception checks to cover all possible infinite loops. Also, remove the writeBarrierActive member from QV4::EngineBase. It isn't used.

| | | | | | | | | | | Member functions in ES7 can not be called as constructors and will throw a type error when trying. Some more fixes are needed here, as they also do not have a prototype property. Change-Id: Ieb920163acaa68d4ff0ff73ae4c1015e883b406f Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Add basic support for EcmaScript classesYulong Bai2018-06-261-0/+1
| | | | | | | | | | | | | | | | Most of the class creation is done inside the runtime in the CreateClass method. Added a corresponding instruction to the interpreter and jit. The compiled data now contains an array of classes containing the compile time generated layout of the class. Currently, classes without an explicit constructor and classes with inheritance are not supported.

* garbage collect InternalClassLars Knoll2018-04-121-2/+2
| | | | | | | | | | | | | | | | Internal classes are now allocated and collected through the GC. As they are important to the deletion of other objects (because of the vtable pointer living inside the internal class), they need to get destroyed after regular objects have been sweeped. Achieve this by using a separate block allocator for internal class objects. Our lookups do often contain pointers to internal classes, so those need to be marked as well, so we don't accidentally collect them.
