        * dwarf2out.c: Don't assume that `.section ".text"' causes the
        assembler to treat .text as a label for the start of that section,
        as this assumption is false for Solaris 2.x `as'.  Instead, output
        `.section ".text"; .LLtext0:' and use .LLtext0 in label contexts.
        (ABBREV_LABEL, DEBUG_INFO_LABEL, DEBUG_LINE_LABEL, TEXT_LABEL):
        New macros.
        (abbrev_label, debug_info_label, debug_line_label, text_label):
        New vars.
        (dwarf2out_init): Initialize the vars.  Output defn for text_label.
        (dwarf2out_finish): Output defns for the other 3 vars.
        (dw_val_node): Rename val_section to val_section_label, as it's
        now a label, not a section.
        (add_AT_section_offset): Arg is now a label, not a section.
        (print_die, output_die, output_compilation_unit_header,
        output_pubnames, output_aranges, output_line_info,
        dwarf2out_finish): In label contexts, output the section label,
        not the section.
