* Makefile.in (ALLDEPFILES): Add alphabsd-tdep.c.
(alphabsd-nat.o): Depend on alphabsd-tdep.h. (alphanbsd-nat.o): Likewise. (alphabsd-tdep.o): New dependency list. * alphabsd-nat.c (supply_gregset): Use alphabsd_supply_reg. (fill_gregset): Use alphabsd_fill_reg. (supply_fpregset): Use alphabsd_supply_fpreg. (fill_fpregset): Use alphabsd_fill_fpreg. (fetch_inferior_registers): Use struct reg and struct fpreg rather than gregset_t and fpregset_t. Use alphabsd_supply_reg and alphabsd_supply_fpreg. (store_inferior_registers): Use struct reg and struct fpreg rather than gregset_t and fpregset_t. Use alphabsd_fill_reg and alphabsd_fill_fpreg. * alphabsd-tdep.c: New file. * alphabsd-tdep.h: New file. * alphanbsd-nat.c (fetch_core_registers): Use alphabsd_supply_fpreg. (fetch_elfcore_registers): Use alphabsd_supply_reg and alphabsd_supply_fpreg. * config/alpha/fbsd.mt (TDEPFILES): Add alphabsd-tdep.o. * config/alpha/nbsd.mt (TDEPFILES): Likewise.
