something to attach small common symbols to. Then avoid writing out
the (empty) .scommon section for the output BFD.

ECOFF which has two common sections.

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.
* coffcode.h (_bfd_coff_mkobject_hook): Pass aouthdr argument.
(coff_mkobject_hook): Accept aouthdr argument.
* coffgen.c (coff_real_object_p): Pass aouthdr to mkobject_hook.
Handle NULL aouthdr argument.
(coff_object_p): If there is no aouthdr, pass it as NULL to
coff_real_object_p.

* 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.
(coff_write_object_contents): coff_count_linenumbers returns the
number of line number records it found.
* coffgen.c (coff_write_linenumbers): only write out line numbers
in the section they belong to.
debug info. Setup info about linker symbols only, and use
standard bfd fields to hold the info.
* (hppa_object_p): Remove unneeded decls.
* (hppa_new_section_hook): Get rid of most of this.
* libhppa.h (struct hppadata): Remove ten pounds of useless ugly
fat. Remove all knowledge of stabs, remove redundant knowledge of
linker symbols.
* Remove macros for accessing fields which are now gone.
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.
Somewhat more could be done.
Fri Jan 8 15:47:53 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* coffcode.h: Moved many generic functions into coffgen.c. Moved
swapping functions into coffswap.h for ECOFF use. Moved
relocation functions, only used by h8300 and z8k, into reloc16.c.
Added hooks for coffgen.c functions to backend data structure, and
added hook functions. Still more could be done.
* coffswap.h: New file to hold COFF swapping routines.
* coffgen.c: New file to hold generic COFF functions.
* reloc16.c: New file to hold h8300 and z8k specific relocation
functions.
* libcoff-in.h: Added declarations for functions in coffgen.c.
* libcoff.h: Rebuilt to incorporate changes.
* coff-h8300.c: Function name changes.
* coff-z8k.c: Function name changes. Use coff_reloc16_extra_cases
hook rather than defining EXTRA_CASES.
* Makefile.in: Build new files coffgen and reloc16. Added
dependencies of coff-*.o on coffswap.h and seclet.h.
* coffcode.h (coff_real_object_p): use name I386AIXMAGIC rather
than I386SVMAGIC.
(coff_pointerize_aux): don't pointerize a negative tagndx
(sometimes generated by SCO 3.2v4 cc).
* bout.c (calljx_callback, callj_callback,
b_out_get_relocated_section_contents): warn if relocating against
an undefined symbol.
Make a bunch more routines be static.
* hppa.c (fill_spaces): Get rid of this, replace with much better
written setup_sections().
* (setup_sections): New routine to create BFD sections for each
space and subspace in SOM files.
* (hppa_object_setup): Use BFD sections created by
setup_sections() to locate GDB symbol table info.
* (make_unique_section): New routine to create a BFD section. It
ensures that the given name is unique, and will generate a unique
one if necessary.
* (hppa_object_p): Become much more paranoid about file header.
* (make_bfd_asection): Call bfd_make_section to do the dirty
work. Simplify code somewhat.
* (hppa_core_file_p): Use proper name for stack section.
* libhppa.h: Remove millicode_start, millicode_end decls.
on the possible size of any object in a bfd.
* elf.c (bfd_elf_find_section, elf_get_str_section,
elf_get_symtab_upper_bound): Rewrite to avoid NULL pointer
dereferences.
* elf.c (elf_big_vec, elf_little_vec): Document last three
members initialized to NULL.
perhaps we can later remove the the_bfd field from each symbol.
* syms.c (struct symbol_cache_entry): Remove unused field
app_data. Add comment noting that the_bfd is almost redundant,
but not quite.
* aoutx.h, coff-a29k.c, coff-i386.c, coff-i960.c, coffcode.h:
Use new macros bfd_asymbol_bfd and bfd_asymbol_flavour.
* hppa.c (fill_spaces): Make slightly more rebust.
* configure.in: Allow std-host as the "default" host.
Get rid of HPPA/BSD specific code. That will go somewhere else
someday.
* (fill_spaces): Don't spin forever and die if you don't find
$MILLICODE$ subspace.
* (hppa_object_p): Make sure that we have a real honest-to-cthulu
exec file!
* (hppa_core_file_failing_signal, hppa_core_file_failing_command):
Make these work for HPUX.
* (make_bfd_asection): New routine to make section creation a
little easier.
* (hppa_core_file_p): Completely rewrite, leave out bugs.
* libhppa.h: #include the right system files. Redefine all of
the structs/macros for hacking core files to use more sensible
HPUX core file structures.
* targets.c (target_vector): Conditionalize hppa_vec on
HOST_HPPAHPUX, not hp9000s800.
* hosts/hppahpux.h: #include stdlib.h to get correct decls for
malloc and realloc. #define HOST_HPPAHPUX.
