....the kernel will be notified for every stack access. A variation of this method proved too costly on IA32 under the MemGuard implementation [4] briefly described later. 6. 3 IA64 Intel s IA64 architecture supports variably sized register windows (the Register Stack Engine in the Intel vernacular) [7, 8, 9, 10]. In IA64, function s can request an arbitrary number of registers unlike the 24 register window on Sparc. If an overflow or an underflow occurs, the processor stalls while the hardware interacts with the backing store. The actual loading or storing of the registers is done by the hardware instead ....
