        * i386nbsd-nat.c (supply_regs): New function. 
        (fetch_inferior_registers): Use supply_regs to
        provide integer registers.  Use i387_supply_fsave
        to supply FP registers.  Add support for XMM
        registers using PT_GETXMMREGS and i387_supply_fxsave.    
        (store_inferior_registers): Use regcache_collect 
        for integer registers.  Use i387_fill_fsave for
        FP registers.  Add support for XMM registers
        using i387_fill_fxsave and PT_SETXMMREGS. 
        (fetch_core_registers): Use supply_regs for
        integer registers and i387_supply_fsave for 
        FP registers.
        (fetch_elfcore_registers): New function. 
        (i386nbsd_elfcore_fns): New.
        (_initialize_i386nbsd_nat): Register i386nbsd_elfcore_fns. 
        * config/i386/nbsd.mh (NATDEPFILES): Add i387-nat.o. 
        * config/i386/nbsdelf.mh (NATDEPFILES): Likewise.
