(struct gdbarch_tdep): New structure. (LOWEST_PC): Provide a default. (arm_gdbarch_register_os_abi): Declare new function. * arm-tdep.c (arm_abi_names): New array. (process_note_abi_tag_sections): New function. (get_elfosabi): New function. (arm_gdbarch_register_os_abi): New function. (arm_gdbarch_init): Try to determine the ABI of the inferior. If support for that ABI has been built in, then call the appropriate configuration routine. Use gdbarch_num_regs() to get the number of registers. (arm_dump_tdep): New function. (arm_init_abi_eabi_v1, arm_init_abi_eabi_v2, arm_init_abi_apcs): New place-holder functions. (_initialize_arm_tdep): Register them. * config/arm/tm-arm.h (LOWEST_PC): Delete. * armnbsd-tdep.c: New file. * Makefile.in (armnbsd-tdep.o): Add dependencies. * config/arm/nbsd.mt (TDEPFILES): Add it. * config/arm/tm-nbsd.h (LOWEST_PC): Delete. * armnbsd-nat.c: Include regcache.h. * Makefile.in (armnbsd-nat.o): Update dependency list. * arm-tdep.c (arm_get_next_pc): Use printf_filtered for error message.
