Richard Earnshaw 34e8f22ded * 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.
