It's really a matter of terminology; it's called a "stack pointer" because it's a value you pass to "$C" or "::stack" to get a stack out. On SPARC, the stack pointer is *always* pointing to a stack frame, since that's where the register window is saved (register windows are *FUN*), and the term has stuck, even though on x86 "frame pointer" might be a better term.
