* Add fast conversion of a string to an array indexLars Knoll2013-01-041-0/+2
| | | | | | | | This will be required later on when Array gets fixed properly. Change-Id: I37eccf94b202c9a003aab30b078ee24c422359a1 Reviewed-by: Simon Hausmann <simon.hausmann@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>
* Fixes for arguments object in non strict modeLars Knoll2012-12-141-1/+9
| | | | | | | | | | | | | In non strict mode, the arguments object actually reflects the argument as it changes over the lifetime of a function, unless you explicitly delete some of it's properties. The code to implement this is pretty ugly, but still better then the specification :) Change-Id: Ie42ed25c797513615fbc4bdee14145d953f323f3 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Cleanup getPropertyDescriptor and arguments objectLars Knoll2012-12-141-3/+4
| | | | | | | | | | The only place where getProepertyDescriptor was still being used outside of Object itself was the arguments object. Fixed that by reimplementing get, hasProperty, put and canPut in the arguments object. Change-Id: Ie44c7acf857321c65bc0f58915de0353231459c0 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Simplify/speed up retrieving of propertiesLars Knoll2012-12-141-5/+5
| | | | | | | | | | | The hasProperty()/get() sequence used so far is as in the spec, but requires us to lookup the name twice. Instead add a bool hasProperty() to Object::__get__() and use that.

* Prevent accidental allocation of GC managed objects on the regular heapSimon Hausmann2012-12-131-0/+1
| | | | | | | | | Make the regular new operator private. As it turns out no other changes were required, all the existing objects are already allocated on the GC heap, thanks to the new* factor functions in ExecutionEngine.

* Fix access rights for builtin propertiesLars Knoll2012-12-121-1/+7
| | | | | | | | | | | 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.

* Remove IR::Function from the runtime.Erik Verbruggen2012-12-111-9/+35
| | | | | | | | | | 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.
