separate JS stack. In exception handling, we need to be able to compare addresses into the JavaScript portion of the stack with the address of a C++ handler on the stack. Since the stacks are separate on the simulator, we need a JavaScript stack address corresponding to a C++ try catch handler in order to perform valid address comparisons. On the simulator, we now link the C++ try catch handlers indirectly through the JS stack and use the JS stack indirection address for comparisons. JS C++ handler [C++ address] <------ next_ \ \ \----> handler [C++ address] <------ next_ On actual hardware the C++ try catch handlers continue to be directly linked.
