| * Re-add some inline property storageLars Knoll2017-05-081-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that not using any inline property storage comes at a relatively high price in terms of memory consumption, as we always need to also create a memberData for any object. This avoids the memberData creation in quite a few cases, as we use the additional padding we have up to the 32 byte boundary given by the memory manager to store some property data. This complicates property access somewhat. To avoid performance regressions because of this, add specialized QV4::Lookup functions that optimize for properties that are inline or in the memberData struct. Change seems to be performance neutral on v8-bench on x86_64, but reduces peak memory usage when running the benchmark by around 20%.

* | Always pass the ExecutionEngine into lookup callsLars Knoll2017-03-091-9/+8
|/ | | | | | | | | | | | This is required in preparation for proper write barriers, where we'll need to check the engine whether the barrier is enabled. It also makes the lookup calls more consistent, and doesn't affect performance in any measurable way.

* Fix run-time string handling with regards to the new heapSimon Hausmann2014-11-211-31/+31
| | | | | | | | | | | | | | | | | Changed runtimeStrings to be an array of Heap::String pointers instead of indirect String pointers. Later that member along with other GC related members will go into a managed subclass. Meanwhile the generated code no more loads String pointers directly but just passes the index into the run-time strings to the run-time functions, which in turn will load the heap string into a scoped string. Also replaced the template<T> Value::operator=(T *m) with a non-template overload that takes a Managed *, in order to help the compiler choose the non-template operator=(Heap::Base *) overload. This allows removing a bunch of Value::fromHeapObject calls. Change-Id: I20415c0549d33cca6813441a2495976b66d4c00e Reviewed-by: Lars Knoll <lars.knoll@digia.com>
