Add support for IA-64 specific elf header flags.
bfd/ 2000-08-14 Jim Wilson <wilson@cygnus.com> * elf64-ia64.c (elf64_ia64_merge_private_bfd_data): Handle EF_IA_64_REDUCEDFP, EF_IA_64_CONS_GP, and EF_IA_64_NOFUNCDESC_CONS_GP. (elf64_ia64_print_private_bfd_data): Likewise. Also handle EF_IA_64_ABSOLUTE. gas/ 2000-08-14 Jim Wilson <wilson@cygnus.com> * config/tc-ia64.c (md_longopts): Add -mconstant-gp and -mauto-pic. (md_parse_option): Add OPTION_MCONSTANT_GP and OPTION_MAUTO_PIC. (md_begin): Change assignment to md.flag to OR in the new bit. include/elf/ 2000-08-14 Jim Wilson <wilson@cygnus.com> * elf/ia64.h (EF_IA_64_REDUCEDFP, EF_IA_64_CONS_GP, EF_IA_64_NOFUNCDESC_CONS_GP, EF_IA_64_ABSOLUTE): Define.
