* Ensure our builtin constructors are subclassableLars Knoll2018-11-221-1/+1
| | | | | | | | | 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>

* Prefix vtable methods with virtualLars Knoll2018-07-031-2/+2
| | | | | | | | | 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>

* qv4arrayobject: Implement Array.of from ES7Robin Burchell2018-05-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | One small difficulty: We can't accurately tell whether a thisObject is a constructor or not, so right now we're just swallowing all exceptions and creating an array if they occur. This isn't correct, but it isn't trivial to fix, either: I think we would have to somehow mark our builtins that are constructors, and allow those, but use the array fallback for other builtins, calling user functions and bubbling up if they throw. This is probably good enough for the time being though, as writing something like: function Test() { throw "Foo"; } Array.of.call(Test) ... is probably not very likely, compared to more "usual" use.

Remaining failures: built-ins/Array/prototype/includes/get-prop.js fails (due to missing Proxy) built-ins/Array/prototype/includes/length-boundaries.js fails length-boundaries failure is due to strange treatment of edge number values in Value, I think, I haven't yet been able to rectify that one.

* Add Array Iterator objects from ES6 (22.1.5)Robin Burchell2018-05-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | And implement / expose them via: 22.1.3.4 - Array.prototype.entries() 22.1.3.13 - Array.prototype.keys() 22.1.3.29 - Array.prototype.values() 22.1.3.31 - Array.prototype[Symbol.iterator] Most tests for Array iterators now pass. At the same time, expose them on TypedArray's prototype: - 22.2.3.15 %TypedArray%.prototype.keys - 22.2.3.29 %TypedArray%.prototype.values - 22.2.3.6 %TypedArray%.prototype.entries - 22.2.3.31 %TypedArray%.prototype[Symbol.iterator] For TypedArray, test coverage improves a tiny bit (3 passing tests), but the vast majority fail as it seems like the object structure for TypedArray is currently incomplete as far as ES6 expects. It seems that ES6 expects the object structure to be: * %TypedArray% (inherits FunctionObject) (this is the TypedArray intrinsic object, and responsible for initializing the TypedArray instances) * All the TypedArray ctors (e.g. UInt8Array) These inherit %TypedArray%, and make a super call to it to do their work * %TypedArrayPrototype% (inherits Object) (this is the initial prototype for %TypedArray%) * All the ctors have their own separate instance of this * The instances also make use it So, for instance, a lot of the tests attempt to access the prototype like: var proto = Object.getPrototypeOf(Int8Array) var keys = proto.prototype.keys As ES6 expects Int8Array.prototype to be %TypedArray% (22.2.5), this expands to: Object.getPrototypeOf(%TypedArray%) which it expects to be %TypedArrayPrototype%. But since we have no intrinsic object, and the ctors inherit FunctionObject, we instead return the wrong prototype into 'var proto'.

Clang might take the same approach if the constructor of Heap::Object is removed. By making these structs trivial, it also makes them memcpy-able.

* V4: Pass scope around as parameters inside the runtime.Erik Verbruggen2016-06-221-2/+2
| | | | | | | | | | | | | | | | The implementation of many (or all) runtime functions consist of first creating a QV4::Scope, which saves and restores the JS stack pointer. It also prevents tail-calls because of that restoring behavior. In many cases it suffices to do that at the entry-point of the runtime. The return value of a JS function call is now also stored in the scope. Previously, all return values were stored in a ScopedValue, got loaded on return, and immediately stored in another ScopedValue in the caller. This resulted in a lot of stores, where now there is only one store needed, and no extra ScopedValue for every function.

* Fix Managed::as<>() methodLars Knoll2014-07-221-1/+1
| | | | | | | | | | | | | | | The as<> casting method was not doing the right thing in 100% of the cases. It only checked if the object in question was exactly of the type being asked for. It however didn't check if the object was derived from the type. This commit fixes this by adding a parent chain to the vtables, that is then being used to check this safely at runtime.
