* Scope intermediate values when allocating objectsUlf Hermann2019-03-271-1/+3
| | | | | | | | | Otherwise the garbage collector might interfere and we might end up with dangling pointers in random places. Task-number: QTBUG-74190 Change-Id: I253c526ef930b8f0be14e96a42af8b66fda3b22d Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Ensure our builtin constructors are subclassableLars Knoll2018-11-221-2/+9
| | | | | | | | | Respect the newTarget passed into those constructors and make sure we set up the proto chain correctly. Change-Id: I3d12c7dbef4b33660a6715d73e9fb0f89105167a Fixes: QTBUG-71138 Reviewed-by: Erik Verbruggen <erik.verbruggen@qt.io>
* Cleanups in Value/PrimitiveLars Knoll2018-09-171-10/+10
| | | | | | | | | | | | Get rid of Primitive and move the corresponding methods directly into Value. Mark many methods in Value as constexpr and turn Value into a POD type again. Keep Primitive as a pure alias to Value for source compatibility of other modules that might be using it.

* Add support for yield*Lars Knoll2018-09-071-0/+3

* Fix super property accessLars Knoll2018-08-311-2/+8
| | | | | | | | | Super properties work in a rather special way by accessing a 'home object' on the function object, and reading from it's prototype. Change-Id: I666334c9c27048c6c2ba6770dd8c9f56aecbee14 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Implement IsConstructor for Function objectsLars Knoll2018-08-231-10/+0
| | | | | | | | Use the jsConstruct member in the function object for this and set it to a nullptr for methods that are not a constructor. Change-Id: I63d2971b23b2596a8e3b6d2781f0d9ed3208693b Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Fix naming of methods defined in object or class literalsLars Knoll2018-08-011-2/+2

* Fix class members that are generatorsLars Knoll2018-07-031-0/+18
| | | | | | | Properly support member functions that are generators in classes. Change-Id: I5fc8d5b58a17c61a446b43d6576bb83de5ecd920 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Refactor initialization code for JS stack framesLars Knoll2018-07-031-23/+9
| | | | | | | | | Move code into qv4stackframe_p.h, so that it can be re-used from different places. Clean up VME::exec and the generatorfunctions using this. Change-Id: Ib4f7eceeb5f55d98dd6ccf2584d13a3b864caea1 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Smaller refactoring of VME::exec() to preapre for upcoming changesLars Knoll2018-07-031-2/+2
| | | | | | | | | We'll need a more flexible interface here to support derived constructors properly. There's also quite some code in the generator functions that could benefit from some cleanups.

* Implement support for new.targetLars Knoll2018-07-031-3/+3
| | | | | | | | | Support the new.target meta property in the codegen, and add support for passing the newtarget into the constructor vtable methods and the execution context. Change-Id: I62ea58e5e92d894035a76e35776203e9837c383b Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Prefix vtable methods with virtualLars Knoll2018-07-031-5/+5
| | | | | | | | | Turns out that the overloading of vtable methods and regular ones is problematic in some cases. So let's rather make it explicit which methods are part of the vtable, and which aren't. Change-Id: Ifee32a26104d30f3c82bca8b5a9cdea2d4f4f526 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Add Proxy support for prototype handlingLars Knoll2018-06-251-4/+4
| | | | | | | | | | | | | | Cleanup get/setPrototypeOf and fix some smaller incompatibilities in the default implementation for Object. Add the methods to the vtable and reimplement them according to spec for ProxyObjects. Clean up the Object.prototype.get/setPrototypeOf/__proto__ methods and fix a smaller bug in the Reflect API for those methods.

* Minor cleanup with bytecode pointer typesSimon Hausmann2018-05-281-1/+1
| | | | | | | | | | | | Even though we consider the bytecode to be a sequence of unsigned bytes, we store it as const char * (so unsigned except on arm) everywhere, because that makes it convenient to work with QByteArray's constData(). By using const char * consistently we can get rid of at least one more reinterpret_cast. Change-Id: I7a803e4201381c39eec2fdc6497d9bf36a1c2b6b Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Fix the prototype of the Generator prototype objectLars Knoll2018-05-131-0/+1

* Ensure we have a lexical scope for global codeLars Knoll2018-05-111-1/+1
| | | | | | | | | | | | | | | This requires a bit more work than simply pushing a new BlockContext for the lexically declared variables, as eval() and the Function constructor operate on the global scope (including the lexically declared names). To fix this introduce Push/PopScriptContext instructions, that create a BlockContext for the lexically declared vars and pushes that one as a global script context that eval and friends use.

* Add Generator supportLars Knoll2018-05-031-0/+247
Add support for ES6 generators. Those are currently always executed in the interpreter (we never JIT them), to simplify the initial implementation. Most functionality, except for 'yield *' expressions are supported. 'yield *' will have to wait until we support for(... of ...)
