-	* 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.
