+	* dwarf2out.c (dwarf2_generate_asm_lineno): New function: Generate
+	a DWARF2 line number information sequence.
+
+	*dwarf2out.h: Add prototype for dwarf2_generate_asm_lineno.
+
+	* read.c (generate_lineno_debug): Update comment describing why
+	DWARF2 line number debug information is not generated
+	automatically by this function.
+
+	* doc/as.texinfo: Note that --gdwarf2 only works on some targets,
+	not all.
+	
+	* config/tc-arm.h (md_end): Define.
+	(DWARF2_LINE_MIN_INSN_LENGTH): Define.
+	
+	* config/tc-arm.c (output_inst): Call dwarf2_generate_asm_lineno
+	if generating DWARF2 line numbers.
+	(arm_end_of_source): New function.  Call dwarf2_finish if
+	necessary.
+
+	* config/tc-hppa.c (md_assemble): Use dwarf2_generate_asm_lineno.
+	* config/tc-m68hc11.c (m68hc11_new_insn): Use dwarf2_generate_asm_lineno.
