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,

* oasys.c: Insert . when UNDERSCORE_HACK is enabled,
fix problem where a relocation which crossed a modification byte
boundary did not work. Fix problem where a relocation near the end
of a data record did not work.
Major change; changed calling convention for
bfd_get_relocated_section_contents so that caller allocates
memory for section data.
* coffcode.h (bfd_coff_get_relocated_section_contents), reloc.c,
seclet.c, targets.c, bfd.c: reflect new convention.
* coffcode.h (styp_to_sec_flags): if styp_flags is not a special
case, then use reasonable default values for SEC_* flags.
* configure.in: Add new host and target configs.
* elf.c (bfd_prstatus, bfd_fpregset): Avoid typename of register
structs, which vary; just use member name.

coff-mips.c, coff-rs6000.c, cpu-h300.c, elf.c, i386aout.c,
newos3.c, stab-syms.c, syms.c: All these files have had their
#includes altered to point to the new places.

added new macro RTYPE2HOWTO to take a load of #ifdefs out of
coffcode.h
* coffcode.h: Started to change the way machine dependencies are
handled, from the nest of #ifdefs to macros defined in the
including coff-<foo>.c
* opncls.c (bfd_close_all_done). Added so that generative
programs like gas can close a bfd without causing bfd confusion.
* libbfd.h (changed becuase of protos)
* amdcoff.c: messed with the way that jmp displacements are
calcualated. This may not yet be totally correct.
* archive.c (coff_write_armap): rewrote the way that ranlibs are
written out.
* coffcode.h (fixup_symbol_value): now doesn't core dump if a non
abs symbol has no section (like a register symbol).
(coff_write_symbol) now zeros auxent before filling it up to help
with sensitive applications.
* libbfd.c (bfd_write_bigendian_4byte_int): added.

`bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
it needs a better name.) All uses changed.
* targets.c: Rename `enum target_flavour_enum' to `enum
target_flavour', and remove the `_enum' from all of the enum
values themselves. All uses changed.

Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
* 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.
* amdcoff.c: (a29k_reloc) fix error message.
* 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.
Install header comments and attribute most modules to their
authors. BFD's name is now officially "Binary File Descriptor",
so remove any conflicting perjoratives.
