* Always set the correct FunctionObject when calling JS functionsLars Knoll2017-09-021-3/+3

* Object: Introduce set and setIndexedRobin Burchell2017-02-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | These names are what the ES6 spec uses for this operation. We also introduce a bool to allow throwing unconditionally if a set fails (which the spec requires the Set operation to do in a number of places). This requirement was also present in ES5, but we ignored it, and thus far got away with it. Long term, put and putIndexed should go away, but I don't feel comfortable porting everything over blindly, as some operations do require throwing, namely: * Various Array & TypedArray methods that alter 'length' * Various RegExp methods that alter 'lastIndex' This change also ports the new Object.assign to use the must-throw version of set(), which coincidentally fixes the one test failure in non-strict mode.

* QML: Make Heap::Object and all subclasses trivialErik Verbruggen2016-10-061-2/+2
| | | | | | | | | | | | 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.

* V4: Pass scope around as parameters inside the runtime.Erik Verbruggen2016-06-221-9/+12
| | | | | | | | | | | | | | | | 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.
