* arm.cc (Arm_exidx_cantunwind::do_print_to_mapfile): New method. (Arm_relobj::do_relocate_sections): Add new parameter for output file to match the parent. (Target_arm::scan_reloc_section_for_stubs): Use would-be final values of local symbols instead of input values. Update code to track changes in gold::relocate_section. * object.cc (Sized_relobj::compute_final_local_value): New methods. (Sized_relobj::compute_final_local_value_internal): New methods. (Sized_relobj::do_finalize_local_symbols): Move code from loop body into private version of Sized_relobj::compute_final_local_value. Call the inline method. * object.h (Symbol_value::Symbol_value): Define destructor. Free merged symbol value if there is one. (Symbol_value::has_output_value): New method defintiion. (Sized_relobj::Compute_final_local_value_status): New enum type. (Sized_relobj::compute_final_local_value): New methods.
