* arm.cc: Replace "endianity" with "endianness" in comments. (Arm_exidx_cantunwind): Ditto. (Arm_relobj::Arm_relobj): Initialize merge_flags_and_attribures. (Arm_relobj::merge_flags_and_attributes): New method. (Arm_relobj::merge_flags_and_attributes_): New data member. (Arm_exidx_cantunwind::do_fixed_endian_write): Fix formatting. (Arm_relobj::scan_sections_for_stubs): Ditto. (Arm_relobj::do_read_symbols): Check to see if we really want to merge processor-specific flags and attributes. Exit early if an object is empty except for section names and the undefined symbol. (Target_arm::do_finalize_sections): Move check for ELF format to Arm_relobj::do_read_symbols. Merge processor specific flags and attributes from a regular object only when we have determined that it is aapropriate. Do not create an .ARM.attributes section in output if there is no regular input object. (Target_arm::merge_processor_specific_flags): Check --warn-mismatch before printing any error. (Target_arm::merge_object_attributes): Ditto. * gold.cc (queue_middle_tasks): Handle the case in which there is no regular object in input. * options.cc (General_options::parse_EB): New method. (General_options::parse_EL): Same. (General_options::General_options): Initialize endianness_. * options.h (-EB, -EL, -no-pipeline-knowledge, -p, --warn-mismatch): New options. (General_options::Endianness): New enum. (General_options::endianness): New method. (General_options::endianness_): New data member. * parameters.cc (Parameters::set_options): Check target endianness. (Parameters::set_target_once): Ditto. (Parameters::check_target_endianness): New method. (parameters_force_valid_target): If either -EL or -EB is specified, use it to define endianness of default target. * parameters.h (Parameters::check_target_endianness): New method declaration. * target.h (class Target): Change "endianity" to "endianness" in comments.
