From: Jason Thorpe <thorpej@netbsd.org>

Subject: * 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.
