Other Architectures

The application of the StackGhost mechanisms to architectures other than Sparc is contingent on a trap into the kernel when registers are pushed onto the stack and again when they are popped off. We know of no common architectures which provide the convenience of the Sparc register window overflow and underflow traps. But we believe there are several architectural features which could approximate the behavior of Sparc.
