Hi Ian, Thanks a lot for the useful suggestion. The "HARD_FRAME_POINTER_REGNUM" which was not a FIXED_REG was defined. The FRAME_POINTER_REGNUM was eliminated to HARD_FRAME_POINTER_REGNUM in the ELIMINABLE_REGS. As the frame pointer was eliminated by a hard register, undefined reference to pseudo frame pointer was solved. Thanks & Regards, Naveen
