binutils/

2008-01-28  H.J. Lu  <hongjiu.lu@intel.com>

	* dwarf.c: Include "elf/common.h".
	(eh_addr_size): Changed to int.
	(dwarf_regnames_i386): New.
	(dwarf_regnames_x86_64): Likewise.
	(dwarf_regnames): Likewise.
	(dwarf_regnames_count): Likewise.
	(init_dwarf_regnames): Likewise.
	(regname): Likewise.
	(frame_display_row): Properly support different address size.
	Call regname to get register name.
	(display_debug_frames): Call regname to get register name.
	Display DW_CFA_def_cfa_register as DW_CFA_def_cfa_register
	instead of DW_CFA_def_cfa_reg.

	* dwarf.h (init_dwarf_regnames): New.

	* objdump.c: Include "elf-bfd.h".
	(dump_dwarf): Call init_dwarf_regnames on ELF input.

	* readelf.c (guess_is_rela): Change argument to int.
	(parse_args): Remove the undocumented upper case options for
	-wX.
	(process_file_header): Call init_dwarf_regnames if
	do_dwarf_register is true.
