* 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.
