* Clean up memory manager ownershipSimon Hausmann2013-01-031-2/+3
| | | | | | | | Since we have now only one memory manager, we might as well let the ExecutionEngine create and own it. Change-Id: I908adadf64da59e0b8f4c09d4d9502785399cb99 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Micro optimization of StringPoolJędrzej Nowacki2012-12-141-3/+5
| | | | | | | | | | In destructor we do not need to create a copy off all pointers. By hiding StringPool::strings in class private section we reduce risk of it being accidentally copied. Change-Id: I1b9df6bf9e49bd6926e84b8eac6b3d904277e50a Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Remove ExecutionEngine::identifiers.Jędrzej Nowacki2012-12-141-4/+1
| | | | | | | | The member was a duplicate of stringPool, there is no point in caching a cache. Change-Id: If34c80ee120dfaff1dd94326625b02d8014806dc Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Fix execution with MM_AGGRESSIVE_GC=1Simon Hausmann2012-12-141-0/+1
| | | | | | | | | Make sure that the current context pointer is initialized to the root context, so that early GC runs before the first function call find an initialized pointer in MemoryManager::collectRoots.

* Fix access rights for builtin propertiesLars Knoll2012-12-121-33/+24
| | | | | | | | | | | According to the spec all builtin properties have writable: true, enumerable: false and configurable:true by default. This is what is now being used. Some constants have all attributes set to false, and there is an extra method for setting these readonly properties.

* Properly set the prototype for regexp objectsLars Knoll2012-12-121-2/+8
| | | | | | | | Clean up the code, so that regexp's get instantiated by the ExecutionEngine Change-Id: Iacc8d9fee0427342156747d6e8814d7660bdbb1a Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Remove IR::Function from the runtime.Erik Verbruggen2012-12-111-1/+11
| | | | | | | | | | This fixes potential leaks of IR::Functions, lowers the memory usage of the functions that the VM needs (because the IR fields are not present in the VM::Function), and makes both managed by the module respectively the ExecutionEngine.

* Properly set up the 'this' pointerLars Knoll2012-12-101-0/+1
| | | | | | | | | Make sure the this pointer is setup correctly for function calls. Also make sure we set the strict mode flag correctly in all functions. Change-Id: Idaacc92bf6469145b7addfac2bbddea588e85c2d Reviewed-by: Erik Verbruggen <erik.verbruggen@digia.com>

* Fix another memory leak.Erik Verbruggen2012-12-041-0/+7
| | | | | | | | | Now we should only leak objects that are VM::Values, and directly related objects like the PropertyTable. The directly related ones will disappear through destructor calls when the VM::Values are GC-ed.

* Remove the DeclarativeEnvironment class againLars Knoll2012-12-021-2/+2
| | | | | | | | | The class is a specification detail that we can implement in a more performant way. ExecutionContext now contains everything needed again. Change-Id: Ideb5f04eeeecaf2b8543676c626e3943e4d6d7a1 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Get rid of variableEnvironmentLars Knoll2012-11-301-1/+1
| | | | | | | | | | | | Found out that the variableEnv is only required for two use cases: To expose the exception in the catch statement, and to create temporary environments for the with() statment. Both can be better handled differently and don't require the overhead of two environments.
