Subject: [PATCH] 	* elf32-mips.c (struct mips_elf_find_line): Define. 
 (mips_elf_find_nearest_line): New static function. 
 (bfd_elf32_find_nearest_line): Define. 	* libelf.h (struct
 elf_obj_tdata): Add find_line_info field.

	* ecoff.c (_bfd_ecoff_swap_tir_in): Move to ecofflink.c.
	(_bfd_ecoff_swap_tir_out): Likewise.
	(_bfd_ecoff_swap_rndx_in): Likewise.
	(_bfd_ecoff_swap_rndx_out): Likewise.
	(cmp_fdrtab_entry): Likewise.
	(mk_fdrtab): Likewise.
	(lookup): Likewise.
	(_bfd_ecoff_find_nearest_line): Just call _bfd_ecoff_locate_line
	to do most of the work.  Allocate find_line_info if necessary.
	* ecofflink.c: Include "aout/stab_gnu.h".
	(_bfd_ecoff_swap_tir_in): Move in from ecoff.c.
	(_bfd_ecoff_swap_tir_out): Likewise.
	(_bfd_ecoff_swap_rndx_in): Likewise.
	(_bfd_ecoff_swap_rndx_out): Likewise.
	(cmp_fdrtab_entry): Likewise.  Use PTR instead of void *.
	(mk_fdrtab): Move in from ecoff.c.  Add debug_info, debug_swap,
	and line_info arguments, and use them instead of ecoff_data.
	(fdrtab_lookup): Move in from lookup in ecoff.c.  Remove abfd
	argument, add line_info argument.  Use it instead of ecoff_data.
	(_bfd_ecoff_locate_line): New function, mostly from the old
	_bfd_ecoff_find_nearest_line in ecoff.c.
	* libecoff.h (ecoff_data_type): Remove find_buffer, fdrtab_len and
	fdrtab fields, replacing them find_line_info field.
	(_bfd_ecoff_swap_tir_in): Declare.
	(_bfd_ecoff_swap_tir_out): Declare.
	(_bfd_ecoff_swap_rndx_in): Declare.
	(_bfd_ecoff_swap_rndx_out): Declare.
	* libbfd-in.h (_bfd_ecoff_locate_line): Declare.
	* libbfd.h: Rebuild.
	* configure.in: Don't use ecoff.o for bfd_elf32_bigmips_vec or
	bfd_elf32_littlemips_vec.
	* Makefile.in: Rebuild dependencies.
