* elf32-rl78.c (rl78_elf_merge_private_bfd_data): Complain if G10
flag bits do not match. (rl78_elf_print_private_bfd_data): Describe G10 flag. * readelf.c (get_machine_flags): Handle RL78 G10 flag. * config/tc-rl78.c (elf_flags): New variable. (enum options): Add OPTION_G10. (md_longopts): Add mg10. (md_parse_option): Parse -mg10. (rl78_elf_final_processing): New function. * config/tc-rl78.c (tc_final_processing): Define. * doc/c-rl78.texi: Document -mg10 option. * rl78.c (E_FLAG_RL78_G10): Define. * lib/ld-lib.exp (check_shared_lib_support): Note that the RL78 does not support shared library generation.
