Fri Jan 15 18:13:17 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com) * coff-msym.c (ecoff_swap_hdr_out, ecoff_swap_fdr_out, ecoff_swap_pdr_out, ecoff_swap_sym_out, ecoff_swap_ext_out, ecoff_swap_rndx_out, ecoff_swap_rfd_out, ecoff_swap_opt_in, ecoff_swap_opt_out, ecoff_swap_dnr_in, ecoff_swap_dnr_out): New functions. * coffswap.h: If NO_COFF_RELOCS is defined, don't define bfd_swap_reloc_in or coff_swap_reloc_out. * coff-mips.c: Added code to link and write out symbolic debugging information, and to swap relocs in and out.
