91a2ae2a30 * config/tc-ia64.h (md_elf_section_type): New macro.
(ELF_TC_SPECIAL_SECTIONS): Drop .IA_64.unwind and .IA_64.unwind_info
        (they're now handled via ia64_elf_section_type.

        * config/tc-ia64.c (unwind): New members saved_text_seg,
        saved_text_subseg, and force_unwind_entry.
        (optimize_unw_records): New function to optimize away unnecessary
        unwind directives.
        (ia64_elf_section_type): New function.
        (output_unw_records): Generate unwind info only if the size is
        non-zero or if it's forced for some other reason (e.g.,
        handlerdata or a personality routine).
        (generate_unwind_image): Don't switch back to previous
        section---stay inside the unwind info section instead so that
        handlerdata that may follow goes into the right place.
        (dot_handlerdata): Force generation of unwind entry and save the
        current active text segment before generating unwind image.
        (dot_unwentry): Force generation of unwind entry.
        (dot_personality): Ditto.
        (dot_endp): Generate unwind table entry only if there is
        some unwind info or the unwind entry was forced.

        * config/tc-ia64.c (make_unw_section_name): New macro to form
        unwind section name.
        (generate_unwind_image): Add "text_name" argument.  Use it to
        form unwind section name.
        (dot_handlerdata): Determine current segment (section) name and
        pass it to generate_unwind_image().
        (dot_endp): Determine current segment (section) name and use
        it to determine the appropriate unwind section name.
        (ia64_md_do_align): Add missing ATTRIBUTE_UNUSED declarations to
        n, fill, and max arguments.
