* Android: Fix crash in String.replace() in release buildsv5.3.0-rc1Eskil Abrahamsen Blomfeldt2014-05-051-4/+7
| | | | | | | | | | | | | | | | | When enabling optimizations in the compiler, it produces bogus code for the regExp->value deref in the line nMatchOffsets += regExp->value->captureCount() * 2 This is a random refactoring to work around the compiler bug. The only line that actually needs to be touched is the one mentioned above, but I replaced all uses of regExp->value so that it wouldn't look too weird.

* Fix copying of Property'sLars Knoll2014-03-101-1/+1
| | | | | | | | | | Data properties don't contain valid data in the set field if they are being stored in Objects.

* Save memory on array dataLars Knoll2014-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | Store a simple vector of Values in the array data, instead of a Vector of Property's. This halfes the memory consumption on 64bit and simplifies our code. If an indexed property gets converted to an accessor property, we simply convert the ArrayData into a SparseArrayData. Add support in SparseArrayData to allocate double slots (two Value's) to hold a full Property in case someone sets an accessor on an indexed property. Some methods still return a Property*, but this is safe, as only the first Value in the Property pointer will ever get accessed if the Property doesn't contain an accessor.

| | | | | | | | | | | | | Move the type flag into the vtable to free up these bits in the Managed class, and not have to set them at object construction time. As we often need to know whether a Managed object is a Object, FunctionObject or String, add some bitflags to test for these to the vtable.

* Avoid side effects when en exception has been thrown.Lars Knoll2013-10-291-5/+39
| | | | | | | | | | | | | | We don't want to check for exceptions after every single line on our runtime methods. A better way to handle this is to add the check in all methods that have direct side effects (as e.g. writing to a property of the JS stack). We also need to return whereever we throw an exception. To simplify the code, ExecutionContext::throwXxx methods now return a ReturnedValue (always undefined) for convenience.
