* Refactor marking GC'ed objectsLars Knoll2013-11-051-2/+2
| | | | | | | | | | | Don't use recursive function calls anymore. Instead, push marked objects onto the JS stack, and then pop them off when their children are being marked. Should reduce stack memory usage, and improves performance by ~5%. Change-Id: I2d37d97579144fcba87ec8e9fd545dd220c01fbb Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Prevent objects from being collected while in their constructorLars Knoll2013-09-221-0/+1
| | | | | | | | | | | | | While objects are being constructed, we don't have a reference to them on the JS stack yet. So the constructor needs to protect itself against being collected by putting the this object onto the JS stack. Added an environment switch MM_EXACT_GC to test exact garbage collection.

| | | | | | | | | | | | | * Use a unified way to store all Managed objects inside a Value, instead of distinguishing between strings and other objects. * On 64 bit we store pointers as pointers, so accessing them through Scoped<> objects is cheap. This implies that doubles are now stored in a mangled form (xor'ed with a mask). Change-Id: I582e0fb167a62c0c527c6bfa3452550e37944069 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
