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
