* alpha-tdep.c (alpha_supply_int_regs, alpha_fill_int_regs): New.

Browse Source 
(alpha_supply_fp_regs, alpha_fill_fp_regs): New.
        * alpha-tdep.h: Declare them.

        * alpha-nat.c (fetch_osf_core_registers): Constify core_reg_mapping.
        Remove zerobuf.  Don't error on UNIQUE.
        (fetch_elf_core_registers): Use alpha_supply_{int,fp}_regs.
        (ALPHA_REGSET_UNIQUE): Provide default.
        (supply_gregset): Use alpha_supply_int_regs.
        (fill_gregset): Use alpha_fill_int_regs.
        (supply_fpregset): Use alpha_supply_fp_regs.
        (fill_fpregset): Use alpha_fill_fp_regs.
        * alphabsd-tdep.c (NUM_GREGS, NUM_FPREGS): Remove.
        (alphabsd_supply_reg): Use alpha_supply_int_regs.
        (alphabsd_fill_reg): Use alpha_fill_int_regs.
        (alphabsd_supply_fpreg): Use alpha_supply_fp_regs.
        (alphabsd_fill_fpreg): Use alpha_fill_fp_regs.
