* Cleanups in Value/PrimitiveLars Knoll2018-09-171-4/+4
| | | | | | | | | | | | Get rid of Primitive and move the corresponding methods directly into Value. Mark many methods in Value as constexpr and turn Value into a POD type again. Keep Primitive as a pure alias to Value for source compatibility of other modules that might be using it.

* Fix super property accessLars Knoll2018-08-311-0/+1
| | | | | | | | | Super properties work in a rather special way by accessing a 'home object' on the function object, and reading from it's prototype. Change-Id: I666334c9c27048c6c2ba6770dd8c9f56aecbee14 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Prefix vtable methods with virtualLars Knoll2018-07-031-1/+1
| | | | | | | | | 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>

* Ensure we have a lexical scope for global codeLars Knoll2018-05-111-1/+1
| | | | | | | | | | | | | | | This requires a bit more work than simply pushing a new BlockContext for the lexically declared variables, as eval() and the Function constructor operate on the global scope (including the lexically declared names). To fix this introduce Push/PopScriptContext instructions, that create a BlockContext for the lexically declared vars and pushes that one as a global script context that eval and friends use.

* use nullptr consistently (clang-tidy)Shawn Rutledge2018-02-261-3/+3
| | | | | | | | | | | | | From now on we prefer nullptr instead of 0 to clarify cases where we are assigning or testing a pointer rather than a numeric zero. 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).

* V4: Pass scope around as parameters inside the runtime.Erik Verbruggen2016-06-221-14/+22
| | | | | | | | | | | | | | | | 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.
