(demand_empty_rest_of_line): Issue an error here. (ignore_rest_of_line): Silently skip to end. (demand_copy_string): Issue an error, not warning. (equals): Likewise. * config/obj-elf.c (obj_elf_section_name): Likewise. (obj_elf_section): Likewise. * config/tc-arc.c (arc_extoper): Remove bogus NULL checks. (arc_extinst): Likewise. * config/tc-ia64.c (dot_saveb): Use demand_empty_rest_of_line. (dot_spill): Likewise. (dot_unwabi): Likewise.
