* | Fix CallData setup for Script::runErik Verbruggen2017-09-151-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | By calling JSCall with an ExecutionContext as first parameter, the compiler would implicitly create a temporary Scope object in order to be able to do the call. However, the scope would then wipe the stack when it is being destructed. So subsequently retrieving argc would always result in 0 arguments. To prevent accidents like this, all Scope constructors are now explicit, and the QV4::Script's ExecutionContext is renamed from scope to context.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the push/pop context instructions to not modify the JS stack anymore, as that can cause conflicts with the VME (and was an ugly hack in any case). Instead, these instructions not return the old context, that is then stored in a temporary. Get rid of Engine::current and Engine::currentContext. The StackFrame structures do now contain the only and authoritive data. This finally gives us a nice setup where we create and destroy frames on the stack when entering/leaving functions.

* V4: Pass scope around as parameters inside the runtime.Erik Verbruggen2016-06-221-12/+14
| | | | | | | | | | | | | | | | 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.
