* arm-tdep.h: New file.
* arm-tdep.c: Include arm-tdep.h. (arm_addr_bits_remove, arm_smash_text_address, arm_saved_pc_after_call) (arm_skip_prologue, arm_call_dummy_words, arm_fix_call_dummy) (arm_print_float_info, arm_register_type, convert_to_extended) (arm_elf_make_msymbols_special, arm_coff_make_msymbol_special) (arm_extract_return_value, arm_register_name): Make static. (arm_software_single_step): Similarly. Fix types in declaration. (arm_register_byte, arm_register_raw_size, arm_register_virtual_size) (arm_store_return_value, arm_store_struct_return): New functions. (arm_gdbarch_init): Register the above functions. Also register call_dummy_start_offset, sizeof_call_dummy_words, function_start_offset, inner_than, decr_pc_after_break, fp_regnum, sp_regnum, pc_regnum, register_bytes, num_regs, max_register_raw_size, max_register_virtual_size, register_size. Set up prologue_cache.saved_regs here, rather than ... (_initialize_arm_tdep): ... here. * config/arm/tm-arm.h (struct type, struct value): Delete forward declarations. (arm_addr_bits_remove, arm_smash_text_address, arm_saved_pc_after_call) (arm_skip_prologue, arm_call_dummy_words, arm_fix_call_dummy) (arm_print_float_info, arm_register_type, convert_to_extended) (arm_elf_make_msymbols_special, arm_coff_make_msymbol_special) (arm_extract_return_value, arm_register_name): Delete declarations. (SMASH_TEXT_ADDRESS, ADDR_BITS_REMOVE, FUNCTION_START_OFFSET) (SKIP_PROLOGUE, SAVED_PC_AFTER_CALL, INNER_THAN, BREAKPOINT_FROM_PC) (DECR_PC_AFTER_BREAK, PRINT_FLOAT_INFO, REGISTER_SIZE, NUM_REGS) (REGISTER_NAME, REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE) (REGISTER_VIRTUAL_SIZE, MAX_REGISTER_RAW_SIZE) (MAX_REGISTER_VIRTUAL_SIZE, REGISTER_VIRTUAL_TYPE, STORE_STRUCT_RETURN) (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE, CALL_DUMMY_WORDS) (SIZEOF_CALL_DUMMY_WORDS, CALL_DUMMY_START_OFFSET, FIX_CALL_DUMMY) (SOFTWARE_SINGLE_STEP_P, SOFTWARE_SINGLE_STEP) (ELF_MAKE_MSYMBOL_SPECIAL, COFF_MAKE_MSYMBOL_SPECIAL) Delete. (arm_pc_is_thumb, arm_pc_is_thumb_dummy, thumb_get_next_pc) (arm_get_next_pc): No-longer static -- these are needed by the RDI interface. * arm-linux-nat.c arm-linux-tdep.c armnbsd-nat.c: Include arm-tdep.h. * remote-rdi.c remote-rdp.c: Likewise. * Makefile.in (arm-linux-nat.o, arm-linux-tdep.o arm-tdep.o) (armnbsd-nat.o, remote-rdi.o, remote_rdp.o): Update dependencies. * config/arm/tm-nbsd.h (SOFTWARE_SINGLE_STEP_P): Delete bogus definition. * arm-tdep.h (ARM_A1_REGNUM, ARM_A4_REGNUM, ARM_AP_REGNUM) (ARM_SP_REGNUM, ARM_LR_REGNUM, ARM_PC_REGNUM, ARM_F0_REGNUM) (ARM_F3_REGNUM, ARM_F7_REGNUM, ARM_FPS_REGNUM, ARM_PS_REGNUM): Renamed from non-ARM_ prefixed definitions. * arm-tdep.c armnbsd-nat.c arm-linux-nat.c arm-linux-tdep.c: Update all uses of above. * remote-rdi.c remote-rdp.c: Likewise. * arm-linux-nat.c (ARM_CPSR_REGNUM): Renamed from CPSR_REGNUM.
