only slightly for different targets.
* libecoff.h: Added prototypes for ecoff.c functions.
(ecoff_backend_data): New structure.
(ecoff_tdata): Added backend_data field. Changed external data
pointers to be PTR rather than to a particular struct.
(ecoff_symbol_struct): Moved in from coff-mips.c.
* coff-alpha.c, coff-mips.c: Moved common functions into ecoff.c.
Added ECOFF backend structures. Include ecoffswap.h.
* coff-msym.c: Removed; superseded by ecoffswap.h.
* bfd.c: Include coff/internal.h.
* Makefile.in (BFD_LIBS): Removed coff-mips.o and coff-msym.o.
Added ecoff.o.
(BFD64_BACKENDS): Added coff-alpha.o.
(CFILES): Removed coff-msym.c. Added ecoff.c.

(coff-mips.o): Added dependency on ecoffswap.h and coff/ecoff.h.
(ecoff.o, coff-alpha.o): New targets.
(coff-msym.o): Removed target.
(ecoff_write_object_contents): If not D_PAGED, don't add the
section headers to text_size. If not D_PAGED, set the magic
number to OMAGIC rather than ZMAGIC. If creating a D_PAGED
executable, the executable must fully occupy an even number of
pages.
(ecoff_set_symbol_info, make_bfd_asection, ecoff_little_vec,
ecoff_big_vec): Consistently set section alignment power to 4,
since ECOFF sections should be multiples of 16 bytes.
(ecoff_little_vec, ecoff_big_vec): Added D_PAGED to object_flags.
Made ar_pad_char and ar_max_namelen agree for both.
systems.
* coffcode.h (styp_to_sec_flags): Set SEC_SHARED_LIBRARY for a
STYP_NOLOAD | STYP_BSS section. Don't set SEC_NEVER_LOAD for a
STYP_INFO section.
(coff_compute_section_file_positions): Force vma and lma of _LIB
section to be zero.
(coff_set_section_contents): Count number of entries in new lma
field, not in vma.
* coffgen.c (make_a_section_from_file): Force lineno_count of
SEC_SHARED_LIBRARY section to be zero, since it is non-zero on the
SCO 3.2v4 shared library.
* seclet.c (rel): Copy over any section with contents, not just
loadable sections.
* coff-mips.c (ecoff_make_empty_symbol): Zero out newly allocated
symbol.
(ecoff_write_object_contents): Added BFD_ASSERT calls to ensure
relocs are reasonable.
* coff-msym.c: Eliminated uses of DEFUN.
(ecoff_swap_tir_out): New function.
debugging symbols.
(ecoff_get_debug): Offset the fdr adr by the adr of the first pdr,
for compatibility with tools from MIPS.
* config/bigmips.mt: New file; default vector is ecoff_big_vec.
* config/irix3.mt, config/irix4.mt: Removed.
* configure.in (mips-*-ecoff): New target; uses bigmips.mt.
(mips-sgi-*, mips-big-*): Use bigmips rather than irix3.
something to attach small common symbols to. Then avoid writing out
the (empty) .scommon section for the output BFD.

* coff-mips.c: Completed support for linker and binutils.
* section.c (SEC_IS_COMMON): New section flag, needed for MIPS
ECOFF which has two common sections.
(bfd_com_section): Set SEC_IS_COMMON flag.
* bfd-in.h (bfd_is_com_section): New macro to test SEC_IS_COMMON.
* aoutx.h, archive.c, bout.c, coff-a29k.c, coff-m88k.c,
coff-mips.c, coffgen.c, ieee.c, oasys.c, reloc.c, syms.: Use
bfd_is_com_section macro rather than checking for equality to
bfd_com_section.
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.
Fri Jan 8 15:47:53 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* bfd.c (struct _bfd): Added ecoff_tdata to tdata union.
* targets.c (enum target_flavour): Added bfd_target_ecoff_flavour.
* coff-msym.c: Use DEFUN for function definitons.
* coff-mips.c: Added code to read and print symbols, and to find
line numbers.
Eliminate all PROTO calls, replace with PARAMS for readability.
* aoutx.h: Add type to callback parameter.
* coff-mips.c: Don't call trad-core.h, not needed.
* trad-core.c: Incorporate trad-core.h declarations. Fix comments.
* trad-core.h: Eliminate, unused.

Now a bfd knows whether underscores are normally prepended
to symbols in its file format. Helps with error messages.
* aout-adobe.c, aout-target.h, bout.c, coff-a29k.c, coff-h8300.c,
coff-z8k.c: targets set so they have leading underscore
* coff-i386.c, coff-i960.c, coff-m68k.c, coff-mips.c, coff-m88k.c,
coff-rs6000.c, coff-we32k.c, elf.c, ieee.c, srec.c: targets set
without leading underscore flag
* targets.c: add symbol leading char to xvec description
* bfd-in.h (bfd_get_symbol_leading_char): new macro.
* ecoff.c: If compiling for DEC3100, use trad_unix core files,
else dummy out the core file support.
* trad-core.c (trad_unix_core_file_p): If HOST_DATA_START_ADDR is
specified, use it to locate the data section.
* coffcode.h (coff_write_symbols): Declare buffer as bfd_bytes
rather than as chars (lint).
bfd.texinfo oasys.c opncls.c reloc.c srec.c: More documentation on
lint fixes.
* amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
29k coff by David Wood (wood@lab.ultra.nyu.edu).
Remove obstack.h to ../include and obstack.c to ../libiberty.
Move COFF symbol swapping code to coffswap.c where GDB can call it but it
won't be duplicated if we have N different COFF targets.
Add support for traditional Unix core files (with a upage). This support
is from an Ultrix port, but is probably slightly broken now.
Improve bfd_release's of obstack'd items on error returns.
gcc -Wall fixes.
Handle section alignment slightly better in coff, and comment where it
needs more work (on page-aligning virtual vs file addresses for DPAGED).
Use set_tdata everywhere that tdata is set, to avoid "cast to the left
of assignment" problems with some compilers.
Move bfd_alloc, bfd_zalloc, bfd_realloc, and bfd_release into libbfd.h
(from bfd.h) since they are internal routines.
Remove the redundant suffix "_struct" from struct tags.
Set symbol count early in file reading, before slurping in the syms,
for GDB's use.
