* V4: Slim down FunctionObjectUlf Hermann2024-05-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most FunctionObjects do not actually need their custom jsCall members. They will only call the functions from the vtable anyway. FunctionObject can therefore be split into a static and a dynamic variant. Only the dyanmic variant needs to carry (and invoke) the extra pointer. The jsCallWithMetaTypes pointer is completely pointless because none of the dynamic functions actually implement it. Furthermore, the QV4::Function and QV4::ExecutionContext pointers in FunctionObject are only needed by actual JavaScript functions. The builtins that like to be dynamic functions never need them. Therefore, split out another class for this. In the generic FunctionObject, we need the capability to decide at run time whether the function shall be a constructor or not. Add a flag to replace the check for jsCallAsConstructor. Also, where we can, avoid the pessimization of checking whether a function is a constructor before trying to call it as constructor. Rather have the default implementation throw the exception. As a side effect, for most functions we don't need an ExecutionContext anymore. The engine is enough.

Also, replaced cases where 0 was passed as Qt::KeyboardModifiers with Qt::NoModifier (clang-tidy replaced them with nullptr, which waas wrong, so it was just as well to make the tests more readable rather than to revert those lines).

* QML: Make Heap::Object and all subclasses trivialErik Verbruggen2016-10-061-3/+3
| | | | | | | | | | | | 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/+1
| | | | | | | | | | | | | | | 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 Verbruggen2016-06-221-2/+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.
