* alpha-tdep.c (alpha_supply_int_regs, alpha_fill_int_regs): New.
(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. * config/alpha/nm-linux.h (ALPHA_REGSET_UNIQUE): New.
