Subject: Re:Re: Fix dwarf3 compile_unit debug info

	* dwarf2out.c (dw_ranges_by_label_ref): New typedef.
	(dw_ranges_struct): Rename block_num to num.  Adjust.
	(dw_ranges_by_label_struct): New.
	(ranges_by_label, ranges_by_label_allocated,
	ranges_by_label_in_use): New variables.
	(add_ranges_num): Factored most of the code out of...
	(add_ranges): ... this one.  Rewrite in terms of the former.
	(add_ranges_by_labels): New.
	(output_ranges): Output by-label ranges.
	(dwarf2out_finish): Output range for multiple-section
	compile_unit.  Output standard DW_AT_low_pc in addition to
	unexpected DW_AT_entry_pc.

This is OK. Did you consider writing a testcase for it?
