* ns32k-tdep.c: include gdbtypes.h, inferior.h, regcache.h,
target.s, arch-utils.h, ns32k-tdep.h. Make many functions static. Rename some register numbers to put them in ns32k-tdep private namespace. (ns32k_get_saved_register, ns32k_gdbarch_init_32082, ns32k_gdbarch_init_32382, ns32k_gdbarch_init, ns32k_dump_tdep): New functions. (_initialize_ns32k_tdep): Use gdbarch_register. * ns32k-tdep.h: New file. * ns32knbsd-tdep.c: New file. * config/ns32k/nbsdaout.mt (TDEPFILES): Add ns32knbsd-tdep.o. * config/ns32k/tm-nbsd.h: Include "ns32k/tm-ns32k.h". (IN_SOLIB_CALL_TRAMPOLINE, REGISTER_NAME, NUM_REGS, REGISTER_BYTES, REGISTER_BYTE): Remove. * config/ns32k/tm-ns32k.h: New file. * config/ns32k/tm-umax.h: Remove.
