* Clean up memory manager ownershipSimon Hausmann2013-01-031-1/+1
| | | | | | | | 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 Nowacki2012-12-141-1/+1
| | | | | | | | | | 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 Nowacki2012-12-141-2/+0
| | | | | | | | 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>

* Properly set the prototype for regexp objectsLars Knoll2012-12-121-1/+2
| | | | | | | | 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/+5
| | | | | | | | | | 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.

* Add a MemoryManager, which does GC for the interpreter.Erik Verbruggen2012-12-081-1/+3
| | | | | | | | | Todo: - stack walking for MASM - fix all TODOs/FIXMEs and hidden treasures (bugs). Change-Id: I36f8cdc3a545df7287ce1df17b3570a9c017865e Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* Fix another memory leak.Erik Verbruggen2012-12-041-0/+1
| | | | | | | | | 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>
* Add some debugging infrastructure to the interpreter.Erik Verbruggen2012-11-291-1/+7
| | | | | | | | | This currently mainly intended to be useful in a C++ debugger. The infrastructure makes it a lot easier to access (parent) contexts, find function names, etc. Change-Id: I0493d3a3bd4bf5c3a03379c1a2b545ed76862cd5 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

Add two new builtin methods to enter and leave a with scope. Implement support for the builtin's in masm. Make sure exception handling works across with scopes.
