mips.h (CAN_ELIMINATE): Don't eliminate rap to $fp (s8), but rather HARD_FRAME_POINTER_REGNUM.
* config/mips/mips.h (CAN_ELIMINATE): Don't eliminate rap to $fp
(s8), but rather HARD_FRAME_POINTER_REGNUM. Add parentheses
where appropriate. Make the second reference to
leaf_function_p a function call, as intended. Reindented.
