* Convert builtins in TypedArray, ArrayBuffer and DataViewLars Knoll2017-01-251-36/+33

* QML: Also check for correct destroy() chainingErik Verbruggen2016-10-061-0/+1
| | | | | | | | | Check that the destroy() method of Heap::Base was called when a Managed object needs destruction. This checks if a call to the parent's destroy() method was accidentally omitted.

* QML: Make Heap::Object and all subclasses trivialErik Verbruggen2016-10-061-5/+7
| | | | | | | | | | | | GCC6 might dead-store-eliminate out our secret write to Base::mmdata, because it expects all memory content to be "undefined" before constructor calls. 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.

* Fix conversion of QByteArray back to String in JavaScriptSimon Hausmann2016-08-301-0/+10
| | | | | | | | | | | | | | | Commit 3b7e2a69f7eb8597c807de39b4de39721e9e2bd2 changed behavior so that QByteArray is converted to the JS ArrayBuffer type, which is a better fit than QVariant. However ArrayBuffer does not have a toString method in the spec, and therefore any previous implicit toString conversion such as when passing to JSON.parse() would fail. To restore compatibility this patch adds a non-spec toString() that performs an UTF-8 conversion, as it was done previously through QVariant's toString.

* V4: Pass scope around as parameters inside the runtime.Erik Verbruggen2016-06-221-12/+18
| | | | | | | | | | | | | | | | 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.
