	* dwarf2.c (struct dwarf2_debug): Add field debug_sections.
	(read_section): Add sec argument. Adjust the code to get section
	names from it.
	(read_indirect_string): Adjust call to read_section.
	(read_abbrevs): Ditto.
	(decode_line_info): Ditto.
	(read_debug_ranges): Ditto.
	(DWARF2_DEBUG_INFO, DWARF2_COMPRESSED_DEBUG_INFO): Remove.
	(find_debug_info): Add debug_sections parameter.  Use it instead
	the above macros.
	(place_sections): Get section names from stash.
	(find_line): Add debug_sections argument.  Initialize
	debug_sections field of stash from it.
	Adjust calls to find_debug_info.
	(_bfd_dwarf2_find_nearest_line): Add debug_sections argument.
	Adjust call to find_line.
	(_bfd_dwarf2_find_line): Adjust call to find_line.
	* libcoff-in.h (struct dwarf_debug_section): New declaration.
	(coff_find_nearest_line_with_names): Likewise.
	* libcoff.h: Regenerate.
	* libbfd-in.h (struct dwarf_debug_section): Move declaration.
	(dwarf_debug_sections): Likewise.
	(_bfd_dwarf2_find_nearest_line): Add debug_sections argument.
	* libbfd.h: Regenerate.
	* elf.c (_bfd_elf_find_nearest_line): Adjust call to
	_bfd_dwarf2_find_nearest_line.
	* elfxx-mips.c (_bfd_mips_elf_find_nearest_line): Ditto.
	* elf64-alpha.c (elf64_alpha_find_nearest_line): Ditto.
	* elf32-arm.c (elf32_arm_find_nearest_line): Ditto.
	* coffgen.c (coff_find_nearest_line_with_names): New function.
	(coff_find_nearest_line): Calls coff_find_nearest_line_with_names.
	* coff-rs6000.c (xcoff_debug_sections): New constant.
	(xcoff_find_nearest_line): New function.
	(rs6000coff_vec): Use xcoff_find_nearest_line.
	(pmac_xcoff_vec): Ditto.
