Various changes to get linker working again for a.out:
* don't set/adjust section file positions or vmas more than once
* use correct page size and segment size when calculating them
* deal with some variations in a.out implementations
Tested on sun4 and sun4->sun3 so far, will be testing further but
needed to get wider exposure&testing. See ChangeLog for details.
Also:
* coffcode.h (coff_write_relocs): Write out swapped reloc, not
pre-swapped version.
* hosts/sparc.h (abort, exit): Hide these names if compiling with
gcc version 2, to avoid warnings.
* cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
files will eventually contain processor specific bits for bfd,
like strange relocation information and dis/assembly. So far only
the H8 has been even partially done. This work also ties in with
the change in handling architectures.
* aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
discover the architecture of the bfd. (sunos4_callback) calls the
function bfd_set_arch_mach rather than stuffing stuff directly
into the bfd. (sunos4_write_object_contents), changed names of
accessor functions.
* aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
setup the environment.
* archive.c: (bfd_slurp_coff_armap) coff archives always have the
headers in big endian format, regardless of the endianess of the
host or target.
* archures.c: totally changed. Now an architecture is represented
with a pointer to an info structure rather than an enumerated type
and a long. The old info is available as two elements in the
structure. Future enhancements to architecure support will
involve pointers to methods being placed into the info structure.
* bfd.c: changed the definition of the bfd structure for the new
architecture stuff.
* bout.c: (b_out_set_arch_mach) changed to use the new
architecture mechanism.
* coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
the new architecture mechanism.
* configure.in: added h8 stuff.
* ieee.c: too many changes to note. Now ieee files written with
bfd gas and ld can be read by gld and ieee only linkers and
simulators.
* libbfd.c, libbfd.h: changed prototype of bfd_write.
* newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
than fixing the structure directly.
* oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
than fixing the structure directly.
* opncls.c: (new_bfd) makes sure that bfd_init has been called
before opening a bfd.
* srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
rather than fixing the structure directly.
* targets.c: (target_vector) now by defining SELECT_VECS (perhaps
in the t/hmake file) a user can select which backends they want
linked with bfd without changing the source.
* init.c: new, looks after initializing modules.
* howto.c: for future use, will allow an application to work out
what cookie to use as a handle on a relcoatio howto.
* aoutx.h, archive.c, archures.c, bfd.c, bfd.texinfo, cache.c,
coffcode.h, core.c, format.c, libbfd.c, libbfd.h, libcoff.h,
opncls.c, reloc.c, section.c, syms.c, targets.c (documentation
segments): used BFD (caps) more consistently as a name in
discourse, fixed a few other minor typos and uses of fonts
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.
