Comment on attachment 214424 [details] Patch Why doesn't this just have the code for op_throw call operationDoThrow directly and then perform the jump from JIT code? Seems like that would be an easier design.

Seems like that would be an easier design. Made this suggested change. Also, since all cti_stubs that had exception checks before returning have been eliminated, I removed cti_vm_throw and it's caller ctiVMThrowTrampoline().
