Lu * config/obj-elf.c (obj_elf_parse_section_letters): Make it a fatal error for unknown section attribute. * config/tc-alpha.c (alpha_elf_section_letter): Return -1 for unknown section attribute. * config/tc-ia64.c (ia64_elf_section_letter): Likewise. * config/tc-ppc.c (ppc_section_letter): Likewise. * config/tc-ia64.c (ia64_elf_section_letter): Handle 'o'. (ia64_elf_section_type): Accept "unwind". gas/testsuite/ 2003-05-03 H.J. Lu * gas/ia64/ia64.exp: Add unwind. * gas/ia64/unwind.s: New.
