* | New mark table implementationLars Knoll2017-03-091-13/+16
|/ | | | | | | | | | | | | | | | | | | Automatically generate a table containing the data where JS Values and pointers are in objects in the JS heap. This will allow making the GC mark phase a lot more efficient. A bit of a special hack is currently required for MemberData and ArrayData, as they have a variable length, and we need to read the size from the object. We keep backwards compatibility with the old markObjects() functions for now (calling them if they are defined). Some further work on QV4::String and in a few other places is required before we can get remove the compatibility.

* QML: Make Heap::Object and all subclasses trivialErik Verbruggen2016-10-061-4/+4
| | | | | | | | | | | | 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 Verbruggen2016-06-221-2/+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.
