In current gcc, the frame pointer required hook is a function implemented in the backend. Your backend can decide, on a function-by-function basis, whether a frame pointer is required. It seems to me that that is what you want. Please let me know if I misunderstand. I'm not sure why you are referring to SUBTARGET_FRAME_POINTER_REQUIRED. A few backends define that macro, most do not. Ian
