binutils-gdb/bfd/ChangeLog
Ken Raeburn 20edaa8e77 Lots of changes from gas-bfd work. Includes: 
* working reloc lookup support
 * better support for creation of COFF files from scratch
 * misc doc changes, macro tweaks, "const" additions, typo fixes, etc.
 * one or two ugly kludges that should get cleaned up (but what's one
   or two more, in BFD?)
See ChangeLog for details.

* section.c (bfd_*_symbol, bfd_*_section): Initialize statically.
Make the symbols unmodifiable.
(bfd_section_init): Deleted.
* init.c (bfd_init): Don't call bfd_section_init.
* section.c (bfd_set_section_contents): Ensure that range to be
written is within section boundaries.
(bfd_get_section_contents): Likewise. Don't bother dispatching if
size is zero.
* libbfd.c (bfd_xmalloc): Text of error message should be const.
* coff-i960.c (howto_table): Deleted.
(howto_rellong, howto_iprmed, howto_optcall): New vars;
interesting entries from old howto_table.

* coffcode.h (coff_new_section_hook): Allocate storage for aux
records for section symbol.
(make_abs_section): Unused; deleted.
(renumber_symbols): Re-order symbols so undefined symbols come
last, as COFF format desires.
(coff_write_symbol): Put C_FILE symbols in debug section always.
(coff_section_symbol): New function; creates a symbol with the
same name as a section, and sets up aux records for it.
(coff_add_missing_symbols): New function; adds section symbols to
symbol table if they aren't there already. Should someday also
add a dummy C_FILE symbol if none is present.
(coff_write_object_contents): Add missing symbols before preparing
symbol table to be written.
(coff_slurp_reloc_table): Verify that symbol indices read in are
in a reasonable range.
* libcoff-in.h (struct coff_tdata): New field conv_table_size.
(obj_conv_table_size): Accessor macro.

bfd_section_name, but returns rvalue, not lvalue.
(bfd_get_section_vma, bfd_get_section_alignment): Similar.
(bfd_get_section_flags): Now returns rvalue.

on previous section. If text section VMA doesn't appear to have
been set, make a best guess from the type of file.

not defined.
(MY(vec)): Initialize reloc_type_lookup field.

(bfd_error_trap, bfd_error_vector): Extern, not common.
* aoutf1.h (sunos4_reloc_type_lookup): New function. Handles a
few types of relocs for sparc; will need enhancement.

Wed Dec 18 16:12:25 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* archive.c (normalize): created version for VMS which removes the
VMS directory crap from the front and end of a filename, eg turn
[-.foo]bar.obj;123 into bar.obj
(bfd_construct_extended_name_table): now writes index into an
extended name table in decimal - the same base used to read an
extended name table.
Wed Dec 18 14:40:39 1991 Per Bothner (bothner at cygnus.com)
* aout-encap.c: Fix to use aout-target.h.
* aoutf1.h: Use standard MY_object_p and MY_callback
in aout-target.h. Remove target-specific versions.
* host-aout.c: Re-write to use aout-target.h.
* gen-aout.c: New files use with host-aout.c to generate
host-specific a.out-related parameters.
* Makefile.in: host-aout.o depends on aout-params.h, which is
generated by gen-aout.
* aout-target.h: Make a little more flexible.
* libaout.h, aout-target.h: Removed WORK_OUT_FILE_POSTIONS
macro. Instead, inline it in aout-target.h.
* newsos3.c: Define N_SHARED_LIB(x) as 0 to avoid
a gcc -Wall warning.
* archive.c: Add missing commas in DEFUN macro (2 places).
* elf.c, coffcode.h, aoutf1.h: Use ANSI functions instead of
Berkeley ones, now that libiberty has them:
bcopy->memcpy, bzero->memset, bcmp->memcmp.
* aoutx.h: Various touch-ups: Re-formatting, fix a cast,
remove unused variable.
Tue Dec 17 19:48:59 1991 Fred Fish (fnf at cygnus.com)
* elf.c (elf_core_file_matches_executable_p): Enclose corename
and execname inside HAVE_PROCFS ifdef since they are unused
when it is not defined.
Mon Dec 16 12:00:10 1991 Fred Fish (fnf at cygnus.com)
* elf.c: Flag all sections as either code or data. We can't
be sure what they are anyway, since ELF doesn't fit the
traditional model of text+data+bss very well. Add new local
function elf_read() to simplify code. Record entry point in
the bfd structure.
Thu Dec 12 21:01:22 1991 John Gilmore (gnu at cygnus.com)
* hosts/h-*.h: Configure fopen using ../include/fopen-*.h
rather than N copies of the same lines.
Wed Dec 11 16:39:45 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* cpu-h8300.c: disassemble branch displacements correctly
* coff-h8300.c: put reloc offsets out in 32bits
* makefile.dos, configdj.bat: New files from DJ
* cache.c: fopen with new macros is needed for DOS.
* ieee.c: environ renamed to envi to stop an include file
conflict.
* opncls.c, coff-rs6000.c: more fopens with macros.
Tue Dec 10 04:07:24 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: infodir belongs in datadir.
Sat Dec 7 16:39:23 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* Makefile.in: fix where docdir lives
* aoutx.h, archive.c, archures.c, bfd.c, cache.c, coff-m88k.c,
coffcode.h, core.c, ctor.c, elf.c, format.c, ieee.c, init.c,
libbfd.c, libbfd.h, libcoff.h, opncls.c, reloc.c, section.c,
srec.c, syms.c, targets.c : all new documentation and lint
removal.
Sat Dec 7 07:22:09 1991 John Gilmore (gnu at cygnus.com)
* coffcode.h, srec.c: Lint.
Fri Dec 6 22:58:48 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: install using INSTALL_DATA, added standards.text
support.
* configure.in: mark directory as target dependent. configure
nows works in objdir always so make file existence checks
against ${srcdir}.
Thu Dec 5 22:46:19 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: idestdir and ddestdir go away. Added copyrights
and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
and mandir now keyed off datadir by default.
Wed Dec 4 10:14:17 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* aoutf1.h (sunos_<size>_object_p, sunos4_callback): moved the
computation of arch and machine type so it's worked out before
some_aout_object_p is called.
* aoutx.h: (some_aout_object_p): don't set arch and mach to
unknown.
* archures.c: add extra field 'section_align_power' to hold
default section alignment in object files.
* cpu-a29k.c, cpu-h8300.c, cpu-i386.c, cpu-i960.c, cpu-m68k.c,
cpu-m88k.c, cpu-mips.c, cpu-rs6000.c, cpu-sparc.c, cpu-vax.c:
initialize the new field.
* bout.c (b_out_callback): replace the text size, since aout
fries them.
* aoutx.h: Documentation in the new style
Wed Dec 4 02:00:30 1991 John Gilmore (gnu at cygnus.com)
* bfd.c (bfd_get_mtime): Don't cache mtime any more; only
use the saved value if mtime_set is already set (intended
for archive files, though apparently not used yet).
Tue Dec 3 22:54:50 1991 John Gilmore (gnu at cygnus.com)
* targets.c: Revise comments about how to configure the target
vector, to match reality. Remove mention of obsolete methods.
Remove long lists of capitalized macros that turn into the same
thing in lowercase. Normal vector simply lists all known
lowercase xvec names; all other cases are handled by SELECT_VECS.
* config/mt-i386-coff: Set DEFAULT_VECTOR to real identifier,
not macro name.
* config/mt-i960-{coff,bout}: Use SELECT_VECS to make a short
list of supported targets.
Tue Dec 3 14:06:15 1991 Per Bothner (bothner at cygnus.com)
* archive.c (bsd_write_armap): The pad byte sometimes added to
the string table in a __.SYMDEF member is now
counted as part of the size of the string table.
This is compatible with the old ranlib, as well as Sun's.
Tue Dec 3 10:53:30 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* srec.c: Rewrote to fix many bugs; now gets the record type
right, doesn't choke on input, sets the start address in an S9 and
fills in the filename on an S0.
Sat Nov 30 21:19:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* cpu-h8300.c: Add support for MEMIND addressing mode
* coff-a29k.c: defined RELOC_PROCESSING to take the #ifdef out of
coffcode.h
* coffcode.h: use the new macro if available
* elf.c (elf_corefile_note): cast malloc to avoid warning.
* Makefile.in: Fixed dependencies due to file rename
* aout-encap.c, aoutf1.h, aoutx.h, archive.c, bout.c, coff-a29k.c,
coff-h8300.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
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.
Fri Nov 29 20:04:49 1991 Fred Fish (fnf at cygnus.com)
* config/mh-i386v4, config/mh-i386-elf, hosts/h-i386v4.h: New files.

ELFDATA2LSB cases.
Fri Nov 29 12:16:51 1991 Per Bothner (bothner at cygnus.com)
* syms.c (bfd_decode_symclass): Return 'A'
for symbols that are both absolute and global.
* archive.c (bfd_special_undocumented_glue): Return NULL
if bfd_ar_hdr_from_filesystem returns NULL.
Tue Nov 26 09:10:55 1991 Steve Chamberlain (sac at cygnus.com)
* Makefile.in: added coff-h8300
* configure.in: now h8 is a coff target
* cpu-h8300.c: fix various disassembly problems
* libcoff.h: took out some code which has been #0ed for a long
time.
* targets.c: added h8 coff
* coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c
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
Fri Nov 22 08:11:42 1991 John Gilmore (gnu at cygnus.com)
* aoutx.h (some_aout_object_p): Set the `executable' bit
if the entry point is contained in the text segment, even if the
text segment is at location 0.
* coff-mips.c, coffcode.h: Peter Schauer's patch to kludge in
nonstandard MIPS sections (.rdata, .sdata, etc).
* aoutx.h, bfd.c, coffcode.h, ieee.c, oasys.c, targets.c: CONST lint.
* libbfd-in.h, libbfd.h, aoutx.h, coffcode.h, elf.c, libaout.h:
Rename ALIGN to BFD_ALIGN to avoid conflict with BSD <sys/param.h>.
* libbfd.c: Lint.
* host-aout.c, trad-core.c: Fix write_armap prototypes. Lint.
Thu Nov 21 19:56:40 1991 Per Bothner (bothner at cygnus.com)
* stab-syms.c, syms.c: Moved bfd_stab_name() and bfd_stab_names[]
from syms.c to new file stab-syms.c. Also, since GNU extended
type codes such as N_SETT are no longer in ../include/stab.def,
include them manually.
* stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
* libaout.h: Added prototype for aout_stab_name().
* Makefile.in: Update Makefile for new stab-syms.[co].
Thu Nov 21 11:50:49 1991 John Gilmore (gnu at cygnus.com)
* libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this
rather complicated seeming problem. Eliminate LOGICAL_ versions,
just make N_XXX work by excluding the header from the text segment.
* aoutx.h: Fix comments to match.
Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
* libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
for the "logical" text segment (i.e. never consider the exec
header to be part of the text segment). This change is
needed for consistency with various other parts of bfd and ld.
* aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
and move calculation of obj_textsec(abfd)->size to libaout.h.
* bfd-in.h: Removed bogus ';'.
* Makefile.in: Add MINIMIZE flag to select lean
or bloated target_vector.
* targets.c: Use new MINIMIZE macro, and add trad_core if needed.
* newsos3.c: Fixes to ../include/aout64.h remove need
for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
* aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h
handle both little and big-endian targets, with little
the default unless TARGET_IS_BIG_ENDIAN_P is defined.
* host-aout.c: Add FIXME note.
Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
* targets.c: Make the default target_vector contain
just &DEFAULT_VECTOR. This makes executables a lot smaller.
Old behavior can be gotten by defining ALL_TARGETS.
* aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
Factored out common code into new file aout-target.h.
Saves a lot of duplicate code for a.out variants.
Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)
Get 'make headers' to work when configured with +subdirs.
* Makefile.in: Add $(subdir) to docdir path.

to include names of N_SETT etc.
Thu Nov 14 19:11:13 1991 Fred Fish (fnf at cygnus.com)
* elf.c: Add minimal support for ELF symbol tables. Generates
canonical bfd symbol tables from ELF symbol tables. Change the
name of some functions from bfd_<name> to elf_<name>.
* syms.c: Trivial fix to comment to remove a redundant "to".
Wed Nov 13 17:02:01 1991 John Gilmore (gnu at cygnus.com)
* coff-{i386,m68k,m88k}.c: Change name of file format to standard
form that GDB recognizes as COFF.
Wed Nov 13 09:09:41 1991 Steve Chamberlain (sac at cygnus.com)
* ieee.c (ieee_object_p): cast NULL correctly.
* configure.in: added harris host
* coff-a29k.c: Lots of changes, most from David Wood.
Tue Nov 12 07:21:41 1991 John Gilmore (gnu at cygnus.com)
* coff-m88k.c (coff_write_armap): Just #undef it.
Mon Nov 11 20:30:18 1991 Steve Chamberlain (sac at cygnus.com)
* Makefile.in: standardize on MINUS_G to disable debugging

* elf.c: Additions to support ELF format core files.
* config/mh-amix: Add -DHAVE_PROCFS to HDEFINES, since host
has support for /proc (all the include files in particular).
Mon Nov 11 18:36:47 1991 Per Bothner (bothner at cygnus.com)
* aoutx.h (NAME(aout,find_nearest_line)): Handle the case
of two N_SO stabs, one for directory, and one for filename.
* bfd-in.h (print_vma): Factor out duplicate definition.
Exit a little more gracefully when malloc returns NULL.
* libbfd.c: New function bfd_xmalloc (malloc wrapper).
* opncls.c, syms.c, bout.c, aoutx.h: Replace malloc by bfd_xmalloc.
* libbfd.h: Rre-generated due to libbfd.c update.
Sat Nov 9 13:45:01 1991 Fred Fish (fnf at cygnus.com)
* config/mt-m68k-elf: Define DEFAULT_VECTOR as elf_big_vec.
* elf.c (elf_object_p): Don't try to create a bfd section for
the first ELF section header. It is just a placeholder.
Sat Nov 9 03:04:26 1991 John Gilmore (gnu at cygnus.com)
* coff-rs6000.c, config/mh-rs6000: Make it work on archive and
core files, when compiling native.
* hosts/h-rs6000.h: Define FASCIST_FDOPEN for bfd_fdopenr.
FIXME: The aoutf1.h change below needs to be reversed back
to the way it was.
Thu Nov 7 11:03:55 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
manipulation of lnno fields in lineno structs in a coff-<f>.h
independent way. Override it in coff-<f>.h to your favourite
number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
(coff_swap_lineno_out): modified to use the new macros.
Mon Nov 4 11:38:33 1991 Steve Chamberlain (sac at cygnus.com)
* aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
unknown arch when the magic number doesn't specify the
architecture, since some OSs (eg old sun3s) don't set the number, and
020 is probably the right answer anyway.
Sun Nov 3 12:07:08 1991 Per Bothner (bothner at cygnus.com)
* hosts/h-news.h, hosts/h-rtbsd.h:
Get rid of MISSING_VFPRINTF, since libiberty provides one.
* bfd-in.h (bfd_print_symbol_type_hopw enum): Add new option
bfd_print_symbol_nm, for use by nm.
* aoutx.h (NAME(aout,print_symbol)): Add code for new
bfd_print_symbol_nm option, to print in nm format.
* coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
oasys.c (oasys_print_symbol): Provide stub implementations
for bfd_print_symbol_nm.
* syms.c: New function bfd_decode_symclass, used by nm printer.
New function bfd_stab_name to look up string name of stab code.
Sat Nov 2 14:26:03 1991 Steve Chamberlain (steve at cygnus.com)
* Makefile.in: Added ctor.c
* archures.c (bfd_default_arch_struct) added
bfd_default_reloc_type_lookup.
* coffcode.h: removed a load of #if 0ed code.
(coff_compute_file_section_positions): now works out the section
alignment and size correctly in all cases.
(coff_get_symtab): looks for constructor symbols and calls the
right function when they're found. (coff_canonicalize_reloc):
knows when a section is full of constructors and does the right
thing.
* cpu-m88k.c: Added default_reloc_type lookup to the architecture
description.
* libbfd-in.h: (bfd_default_reloc_type_lookup) defun added.
* libcoff.h: removed #if 0ed code
* reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
arch independent constructor relocation type.
(bfd_reloc_type_lookup): removed the comment "this will go away"
since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
reloc which is used when BFD_RELOC_CTOR falls through to give a
default 32bit reloc for constructors.
(bfd_default_reloc_type_lookup): added.
* aoutf1.h: fixed SEGMENT_SIZE typo.
Thu Oct 31 18:23:06 1991 John Gilmore (gnu at cygnus.com)
* coff-rs6000.c: Change name to "aixcoff-rs6000", to avoid
matching prefix "coff".
* coffcode.h (coff_swap_aux_in, coff_swap_aux_out): Handle
rs/6000 csect records.
Sun Oct 27 16:56:58 1991 Steve Chamberlain (steve at cygnus.com)

Fri Oct 25 02:48:19 1991 John Gilmore (gnu at cygnus.com)
* Rename COFF-related files in `coff-ARCH.c' form.
coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
coff-mips.c, coff-rs6000.c to be exact.
* Makefile.in: Only supply TARGET_DEFAULTS to targets.c, reducing
make output clutter.
* config/mt-*: Ditto.
Thu Oct 24 22:40:07 1991 John Gilmore (gnu at cygnus.com)

just return false rather than overwriting it.
(coff_real_object_p): Understand incoming magic numbers.
(coff_set_flags): Understand outgoing magic numbers.
(coff_compute_section_file_positions): outgoing aouthdr magic #.
(build_debug_section): Add fn for reading debug string section.

* rs6000coff.c: New file.
Thu Oct 24 02:03:24 1991 Fred Fish (fnf at cygnus.com)
* elf.c: Add partial support for ELF format corefiles. Still needs
support for extracting registers from corefiles.
* config/t-m68k-elf: Set DEFAULT_VECTOR to elf_big_vec.
* config/{h-amix,h-dgux,h-irix3,h-ultra3}: For systems where
RANLIB is defined as echo, send the output to /dev/null to help
reduce clutter in the output from doing a make.
Mon Oct 21 17:48:48 1991 John Gilmore (gnu at cygnus.com)
* hosts/h-vaxult.h: Remove malloc/free decls covered in stdlib.h.
Fix HOST_PAGE_SIZE and HOST_SEGMENT_SIZE. From David Taylor.
Mon Oct 21 09:34:11 1991 Steve Chamberlain (steve at rtl.cygnus.com)
* coffcode.h (coff_compute_section_file_positions): make it pad
section size out if there are alignment restrictions so that the
image will be ok on a system where section positions are worked
out by accumulating sizes rather than from the section headers.
* targets.c (proto write_armap). Changed orl_count to unsigned.
* 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.
Wed Oct 16 22:58:45 1991 John Gilmore (gnu at cygnus.com)
* bfd.c: Make sure we don't get a macro strerror().
* opncls.c (bfd_fdopenr): If FASCIST_FDOPEN, use "r", not "r+".
* trad-core.c (trad_unix_core_file_failing_command): Suppress
attempt to recover command, ifdef NO_CORE_COMMAND.
* hosts/h-tahoe.h: Add FASCIST_FDOPEN and NO_CORE_COMMAND;
revamp HOST_*, etc.
* hosts/h-i386v.h: Use <utime.h>, not <sys/utime.h>, unlike POSIX.
Wed Oct 16 12:43:49 1991 Per Bothner (bothner at cygnus.com)
* archive.c (bsd_write_argmap): The size of the ranlib structures
should not include the size field itself.
* aoutx.h, libaout.h (NAME(aout, sizeof_headers)): Use
adata(abfd)->exec_bytes_size field instead of constant macro,
because aoutx.h compiles to a simple .o file shared by
all 32-bits a.out targets.
Wed Oct 16 11:11:05 1991 John Gilmore (gnu at cygnus.com)
* configure.in: Allow i386-sco-sysv.
* bout.c: Remove unused i960_align; lint dummy core file handlers.
* cpu-h8300.c: lint.
* host-aout.c: New strategy. We use common code, include files,
and data structures to handle the file, but set a few parameters
from the host's config file (page size, text start addr, etc).
* libaout.h: Define HP BSD machine types.
* aoutf1.h: Handle reading a.outs with these types.
* trad-core.c: Pass the u.u_ar0 value as the negative of the
virtual-memory-address of the .reg section. We can't just make a
section for "all the regs and nothing else" because only GDB knows
exactly where the regs are (scattered around the upage and stack).
Clean up memory allocation. Remove big- and little-endian
vectors, replace with single vector; this only runs on the host,
in host byte order. Replace byteswap routines with aborts in case
anyone calls them.
* targets.c: There's only one trad_core_vec now.
* aoutf1.h (sunos_core_file_p): VMA of .reg* now needs to be 0.
Tue Oct 15 08:29:03 1991 John Gilmore (gnu at cygnus.com)
* hosts/h-amix.h (free): Fix prototype.
* aoutx.h: Don't use NULL as an integer, for braindead systems
that declare it as (void *)0. (From Peter Schauer.)
Mon Oct 14 17:20:47 1991 Per Bothner (bothner at cygnus.com)
* opncls.c (bfd_fdopenr): Add parentheses to avoid reported
problem with bad Ultrix system headers.
* aoutx.h (NAME(aout,set_section_contents)): Try to handle the
various kinds of alignments for the various kinds of
magic numbers.
Mon Oct 14 14:23:10 1991 John Gilmore (gnu at cygnus.com)
* doc/Makefile: Don't assume . is on the path (from James Clark).

* libbfd.h: Moved ALIGN macro here.
* bout.c (b_out_callback): Replace i960_align by align_power.
* libaout.h (struct aoutdata): Added fields page_size,
segment_size and exec_bytes_size. These help generic code
(in aoutx.h and libaout.h) to figure out where to align
the various segments in a demand paged file.
* libaout.h (WRITE_HEADER): Use new (struct aoutdata) fields
to decide if the exec header counts in a_text (text segment size).
Also, assume D_PAGED flag is set; don't set it here.
* bout.c (b_out_callback): Add initialization of
adata fields page_size, segment_size, and exec_bytes_size.
* host-aout.c (NAME(host_aout, callback) and
NAME(host_aout,mkobject): Ditto.
* i386aout.c (aout386_callback) and new aout386_mkobject): Ditto.
* newos3.c (newsos3_callback) and new newsos_mkobject): Ditto.
* aoutf1.c (sunos4_callback) and new sunos_mkobject): Ditto.
* aoutx.h (NAME(aout,some_aout_object_p)): Don't subtract
EXEC_BYTES_SIZE from the a_test size; this is only appropriate
for some systems (mainly sunos), so do it in the callback instead.
Same routine: Add stuff to the THIS_IS_ONLY_DOCUMENTATION comment.
* aoutx.h (NAME(aout,set_section_contents): Change the way
filepos and size of sections are carried out to support
older styles of demand paged executables.
Fri Oct 11 12:33:36 1991 Steve Chamberlain (steve at cygnus.com)
* bfd-in.h: Added more macros to COFF_SWAP_TABLE.
* bfd.c: Added macros to enable gas to swap coff records.

of bytes swapped, and cleaned up their prototypes.
* configure.in: Added ebmon/coff support
* ecoff.c: Changed null definitions of coff_swap_*_out to conform
to new prototypes
* targets.c: Added new entry points for coff swapping
Fri Oct 11 03:01:52 1991 John Gilmore (gnu at cygnus.com)
Restructure configuration scheme for bfd, binutils, ld.
* include/sys/h-*.h: Move to bfd/hosts/h-*.h.
* configure.in: Revise to symlink sysdep.h to hosts/h-xxx.h.
Change some config names to match other dirs.
* *.c: Include bfd.h before sysdep.h, so ansidecl and PROTO()
get defined first.
* Makefile.in: Use -I. to get sysdep.h. Remove refs to
../include/sysdep.h.
* cpu-i960.c: Strncmp needed a length arg.
* ecoff.c: Don't ever call trad_unix_core_file_p from here.
* i386aout.c: Remove dead N_TXTOFF override.
* trad-core.c: Don't disable the whole file if SUN4_SYS.
* config/: Rename some config files to match up h-*.h names.
Remove all the HOST_SYS definitions from the config files.
* hosts/h-amix.h, h-i386v.h: Define POSIX_UTIME, not USG.
* hosts/h-hp9000.h: Remove USG comment.
* hosts/h-rs6000.h: Include <stdlib.h> for malloc.
* hosts/h-news.h, h-sparc-64.h: New config files that had
previously been kludged in the <sysdep.h> file.
Thu Oct 10 17:54:08 1991 John Gilmore (gnu at cygnus.com)
* config/*: trad-core support is HOST dependent, not target
dependent. Target config files only set DEFAULT_VECTOR and/or
other vector elements. Exception: when host-aout.c is in use,
in which case we're forced to assume we're native (hp, vax,
tahoe). Rename XDEPFILES to HDEPFILES.
* Makefile.in: Rename XDEPFILES.
* config/h-sun*: Don't force static linking.
* trad-core.c: Document how to use it nowadays.
* i386aout.c, newsos3.c: Clean up.
* i386coff.c: Allow 386 coff files to be used as core files too
(for reading core files from embedded systems).
Tue Oct 8 15:30:39 1991 John Gilmore (gnu at cygnus.com)
* Add i386aout.c for a.out support on the i386.
Tue Oct 8 12:18:54 1991 Roland H. Pesch (pesch at cygnus.com)
* reloc.c, section.c, syms.c, targets.c: correct info-node
structure in *doc* comments.
doc/Makefile: stop hiding complaints from makeinfo.
Sun Oct 6 19:10:06 1991 John Gilmore (gnu at cygnus.com)
* aoutx.h (...some_aout_object_p): Take a third parameter,
the internal_exec struct, and avoid ever looking at an
external_exec. All callers changed to read the entire
external_exec struct, swap and check its magic number,
swap in the whole structure, and pass the swapped-in version to
some_aout_object_p.
* bout.c: Bring into modern era. Use single _object_p routine
for big- aand little-endian. Provide internal and external
exec header structs. Use separate swap-in and swap-out routines.
* libaout.h: Move struct internal_exec from ../include/aout64.h
to here. Add obj_symbol_entry_size to struct aoutdata.
* aoutx.h (...some_aout_object_p): Set obj_symbol_entry_size.
* ../include/aout64.h: Change EXTERNAL_LIST_SIZE to
EXTERNAL_NLIST_SIZE. Callers changed.

last byte of transfer, not first byte, is within the section.
* host-aout.c: Remove `BSD' archive support. Lint.
* archures.c: Rename `struct bfd_arch_info_struct' to `struct
bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
`bfd_arch_info_type'. All uses changed.
* reloc.c: Rename `bfd_reloc_status_enum_type' to
`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.
* configure.in, config/h-i386mach: i386 mach host.
* config/t-i386-aout: Use host-aout.c.
* trad-core.c: Give it its own xvec's to make it independent
of other file formats.
* ecoff.c, host-aout.c: Remove refs to trad-core.
* config/t-dec3100, t-hp300bsd, t-tahoe, t-vax: Define TRAD_CORE.
* targets.c: #ifdef TRAD_CORE, include it in the vector.

Thu Oct 3 19:39:55 1991 John Gilmore (gnu at cygnus.com)
* bfd-in.h: enum boolean => enum bfd_boolean for SVR4. Gumby's
prediction is vindicated!
* bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
Remove refs to howto.c, since Steve forgot.
Thu Oct 3 07:49:21 1991 Steve Chamberlain (steve at cygnus.com)
* elf.c: took the abort out of set_arch_mach so that objdump -i will
still work. Now allows any architecture/machine to be set.
Wed Oct 2 13:50:35 1991 Steve Chamberlain (steve at cygnus.com)
* howto.c deleted and moved code to reloc.c
* libbfd.h, libbfd-in.h removed $id stuff for real
* cpu-h8300.c Made it match various different spellings of h8300.
* archures.c: Took out the first char filter which made it only
look for a cpu/arch match when the first chars of supplied and
tested names were the same.
* targets.c removed oasys stuff, pending someone to fix the bugs
in it.
Tue Oct 1 12:29:44 1991 John Gilmore (gnu at cygnus.com)
* Makefile.in, configure.in, targets.c, elf.c: Add preliminary
ELF support good enough for GDB.
* configure.in, config/h-amix, config/t-m68k-elf: Handle
m68k-cbm-svr4 host and target.
* config/t-m68k-coff, t-m88k-coff, t-m88k-aout: Make files nonempty
so `diff' and `patch' can cope.
Tue Oct 1 11:24:31 1991 Steve Chamberlain (steve at cygnus.com)
* archures.c: removed texinfo error
* init.c: added texinfo hooks, and removed initialization error
message.

without complaints.
Tue Oct 1 05:02:53 1991 John Gilmore (gnu at cygnus.com)
* cpu-i960.c: Avoid numerical count of initializers.
Vax Ultrix changes from David Taylor <taylor@think.com>:

* configure.in: Separate vax and tahoe cases, handle ultrix.
* config/t-vax: Add trad-core.o.
* config/h-vaxult: New host system.
Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
* bfd-in.h VERSION, change version number to 0.18, this makes a
gap, but now is the same as the linker version number.
* 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.
Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
* srec.c: Better error checking, partly from Peter Schauer.
(srec_object_p): Avoid assuming any file that starts with 'S' is
an S-record file! (Check for 3 uppercase-hex digits after it.)
(ISHEX): Define new macro for checking supposedly hex characters.
(pass_over): Treat as EOF any S-record line that:
* doesn't have hex in either size character
* produces a size larger than 0x7F
* has an unrecognized type number
Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
* aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
opncls.c: Lint (saber actually).
Thu Sep 26 11:24:24 1991 Per Bothner (bothner at cygnus.com)
* libaout.h (WRITE_HEADERS): Set header's a_text field always.
* newsos3.c: Fixed two types: newos3 -> newsos3.
* reloc.c (bfd_perform_relocation): Fix pc-relative relocation
to use correct segment.
Mon Sep 23 18:24:34 1991 Per Bothner (bothner at cygnus.com)

Fri Sep 20 12:26:01 1991 Stu Grossman (grossman at cygnus.com)
* aoutf1.h (swapcore_sparc): Change name of USRSTACK, fix comment
at top of routine.
Tue Sep 17 17:23:49 1991 Stu Grossman (grossman at cygnus.com)
* oasys.c, configure.in, config/h-irix3, config/t-irix3:
add sgi/irix support.
Thu Sep 12 14:29:09 1991 John Gilmore (gnu at cygint.cygnus.com)
Changes for the AMD 29000 Ultracomputer port from David Wood.
(wood@nyu.edu).
* opncls.c (bfd_fdopenr): Handle NO_FCNTL.
* Makefile.in: Make subdirs work by using $(INCDIR) in the
crude dependencies.

current file's coff symbol format to BFD via the coff_data struct.
(coff_find_nearest_line): obj_icof => coff_data.
(coff_swap_sym_{in,out}): Check that SYMNMLEN == E_SYMNMLEN.
(coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
and DIMNUM == E_DIMNUM.

a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
* libcoff-in.h: Add local_n_btmask, local_n_btshft,
local_n_tmask, local_n_tshift, local_symesz, local_auxesz,

(coff_data, coff_data_type, coff_tdata): Rename struct icofdata.
* config/h-ultra3: Handle a29k-*-* hosts as Ultracomputers.

Tue Sep 3 13:46:19 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* config/* aoutx.h configure* shortened all the h/tmake-xxxx
to h/t-xxxx files so that everything will work on System V.
Fri Aug 23 13:51:06 1991 John Gilmore (gnu at cygint.cygnus.com)
* aoutx.h: Add information on host-aout.c and how to configure
to use it, to the manual.
* configure.in: Tix typo.
* ecoff.c: If compiling for DEC3100, use trad_unix core files,
else dummy out the core file support.

Wed Aug 21 19:13:22 1991 John Gilmore (gnu at cygint.cygnus.com)
* trad-core.c (trad_unix_core_file_p): Use HOST_TEXT_START_ADDR,
etc, rather than TEXT_START_ADDR.
* host-aout.c: Remove #if 0 around whole thing.
Update to modern (32/64-bit) a.out naming conventions.
Include a large chunk of ../include/a.out.gnu.h to get macros that
are not defined by the system include files.
(host_aout_{32,64}_write_object_contents): Use the WRITE_HEADERS
macro used by the other a.out implementations.
* Makefile.in: Give dependencies to OPTIONAL_BACKENDS.
Wed Aug 21 14:33:06 1991 Roland H. Pesch (pesch at cygint.cygnus.com)

texdoc and psdoc; make these depend on generated .texi's
* scanit, (new) unPROTO: turn PROTO macros into ANSI declarations in
doc
* bfd.c, reloc.c, syms.c: minor spelling/wording fixes in doc
portions
* Makefile.in, awkscan-ip, awkscan-p, intobfd,

Wed Jul 31 09:53:52 1991 John Gilmore (gnu at cygint.cygnus.com)
* all files: update copyright notices for GPL version 2.
Install header comments and attribute most modules to their
authors. BFD's name is now officially "Binary File Descriptor",
so remove any conflicting pejoratives.
archures.h: Consists solely of comments; remove it.
Fri Jul 26 18:11:34 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* Makefile.in, bfd.c: Made it compile again.

section.c and syms.c to split the functionality a bit better.
Cleaned up the rest of the files a bit, and added some
documentation.
Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu)
* opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl

* ../include/bfd.h (struct bfd_target): Added new field
"align_power_min" which contains the minimum alignment for a
section. This is used in coff_new_section_hook. The field
insertion necessitates an update of all backends..

filenames too.
* bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
table field inserted.

filenames less than 9 characters.
Thu Jun 6 18:27:38 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
* srec.c: now allows any number of sections to be created in a
file. Outputs addresses of the right length.
Thu May 30 15:30:10 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* bfd.c (bfd_check_format): Fixed problem where when a defaulted
target didn't match, the format got set to the attempted match,
breaking a future test.
*../include/i386coff.h : fixed typo in type field with size
* i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
support in the jump table for the swapping routines exported to
gdb. Now gdb works with the 386.
Tue May 28 17:21:43 1991 John Gilmore (gnu at cygint.cygnus.com)
* Merge in changes from gdb-3.95 release.
Makefile.in: Allow hmake and tmake files to add OFILES.
aoutf1.h:
bfd.c: support specific targets as well as searching. When
searching, take default target in preference to others.
bfd.doc: typos
ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
liba.out.h: Don't hard-code file offsets; use N_ macros for them.
libbfd.h: Support specific targets as well as searching.
opncls.c: Support specific targets as well as searching.
targets.c: Search is short-circuited if default target matches.
liboasys.c, libieee.c: Undo bothner changes that make macros
work to the left of assignment, but which depend on the
representations of different pointer types being the same.
Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* i386coff.c: created.
* coffcode.h: added support for 386.
* Makefile.in: added support for 386.
* ../include/i386coff.h: created
Wed May 22 07:26:38 1991 Steve Chamberlain (steve at cygint.cygnus.com)

(bothner)
* opncls.c: Changed obstack_chunk_alloc use xmalloc
Mon May 20 17:12:17 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* everything: Removed sysdep.h from bfd.h and put back into files
from which it was split out. Now 64 bit version is built with a
-DHOST_64_BIT="long long" on the compile line.
Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
Changed all the [get|put][name] routines to use [get|put]_[size
in bytes].
Put in support for 64 bit work. Now two versions of bfd may be
generated, according to the state of TARGET_64_BIT, one which is
32 bit only, and one which is 64/32 bits.
Created new back end 'demo64' to test 64 bit functionality.
Renamed some files to work on DOS.
* archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
64bit transfer * icoff.c: added 64bit transfer * ieee.c: name
chage, 64 bit transfer. * liba.out.h: Split out common code from
sunos and newsos into liba.out. Name changes and prototype mods. *
libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
prototypes for new functions. * libcoff.h: lint * libieee.h: make
work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
change and 64bit stuff.* newsos3.c: common code removed, new jump
table. * oasys.c: Name change * opncls.c: Portability fixes *
srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
Added demo * aout32, aout64.c include aoutx.h * bout.c: used to
be called b.out.c * coffcode.h: used to be called coff-code.h, now
64bit ized. * demo64.c: 64 bit a.out back end
Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
from bothner
* libieee.h: Make ieee_data and ieee_ar_data macros usable
on LHS of assignment, even when using old compilers.
* liboasys.h: Ditto for oasys_data and oasys_ar_data.
* m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
* newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
* opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
* targets.c: Add declaration of newsos3_vec.
Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* aout.c: fixxed some of the problems with filepos calculation.
(swap_ext_reloc): fixed problem with creation of relocs.
(aout_set_section_contents): fixed filepos problem
* coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
(swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
(swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
(coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
cleaned up. (coff_write_object_contents) cleaned up.
* ecoff.c: Totally different. Now supports ecoff fully.
* icoff.c: fixed problems in relocation callout.
* libcoff.h: (struct icofdata) removed hdr structure from tdata.
* m68kcoff.c: updated target vector.
* sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
choose_reloc_size. (sunos4_write_object_contents) now calls
choose_reloc_size so outputs relocs correctly, also calculates the
size of the sections correctly.
Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
Merge Per Bothner's changes to modularize BFD a.out a bit.
* libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
* ieee.c: Cast enums to int before comparing them, for brain-
dead compilers.
* coff-code.h: Remove coff_get_section_contents, and use the
generic one instead.
* aout.c: Derive new module from sunos.c, containing generic
support code for all kinds of a.out files.
* sunos.c: Remove all code that goes in aout.c. Split out
machine dependent followup in sunos4_object_p into
sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
and redefine only the names we CHANGE, not all the names. Drop
the little-endian vector, and rename the vector as sunos4 rather
than generic.
* b.out.c: Use aout.c routines for most of the work. Slight
changes for the new regime. Remove close_and_cleanup and
get_section_contents in favor of generics. New transfer vector
regime.
* newsos.c: New support for Sony NEWS, another a.out format.
* ecoff.c: Remove close_and_cleanup. New tvec regime.
* icoff.c, m88k-bcs.c: Add write_contents to tvec.
* ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
to tvec.
* opncls.c (bfd_close): Call format-dependent write_contents
routine, if writing, before calling target-dependent
close_and_cleanup routine (which is now always generic, I think).
* srec.c: Use bfd_alloc instead of malloc. Remove
close_and_cleanup and move code from it to
srec_write_object_contents. Add write_contents to tvec.
* targets.c: Remove a.out little vector, replace a.out big
vector with SunOS vector. FIXME: Need Vax support again now.
* libbfd.h: Add write_contents format-dependent-vector to the
bfd_target vector. Supply a generic close_and_cleanup routine.
* liba.out.h: Handle the new aout.c split. Add prototypes for
all routines defined in aout.c. Rename "sunos" things to "aout"
things. Add a few fields where needed for various formats.
* Makefile.in: Add aout.c and newsos.c.
* archive.c, ieee.c, oasys.c: Lint.
Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* ../include/bfd.h
changed forward declaration struct stat; to reduce warnings. Changed
comment on bfd_h_<x>_x.
* ../include/m68kcoff.h, ../include/intel-coff.h,
../include/m88k-bcs.h
Now there are two incarnations of relocs, linenos and syments. One for
internal digestion, and one full of char arrays for I/O. The original
names have gone to detect errors.
* Makefile.in, m68kcoff.c, targets.c
Test new structure code with a 68k coff implementaion
* coff-code.h, icoff.c, coffswap.c, libcoff.h
Fixed all the places where there were problems with the size and
alignments of structures on disk and structures in memory. #ifed out
all the code in coffswap.c, since it should be done using the target
swap routines now.
Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* ieee.c (do_one, ieee_slurp_section_data): now supports the load
multiple reloc command.
* sunos.c (sunos4_set_section_contents): Made it so that sections
are always padded to their alignment size.
Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
* archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
Clean up types and such (saber C problems).
* ecoff.c: Clean up types and such. Remove routines that are
not used. Fix up reading and swapping of shorts from files.
Notes on bfd-0.5.2-patch1a, from Per Bothner:
* a.out.vax.c: Remove two bogus "static" from prototypes.
* ecoff.c: Got rid of lots of non-working junk (that had
been copied directly from coff-code.h).
Updated to be consistent with updates to icoff.c and coff-code.h.
* libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
* sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
but until the target_vector is automatically generated,
it's as good as any. Note that the text offset is the only
difference between NewsOS and SunOs (including magic numbers).
(Most of the sunos_* routines should to renamed bsd_*
and move to a bsd.c file. Then (and when the target_vector
is automatically generated) it might make sense to create
a separate Sony target.)
* sysdep.h: Don't declare fread and fwrite. Causes trouble
on some systems, and doesn't help on others.
Similarly, only define X_OK if not already defined.
* trad-core.c: Don't include sys/stat.h - at least
on NewsOS 3, it has already been included.
Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
* coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
bfd_coff_swap_lineno): Export the routines that byte-swap COFF
symbol tables if necessary when reading them in, so gdb can use
them. Add "bfd_coff_" to the names so they won't conflict with
names in calling programs. FIXME-soon: if coff-code.h is
included in two BFD modules, this will cause duplicate
definitions; the routines should be exported to a separate,
common, module (probably along with a mess of other ones).
Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
Improve modtime support.
* bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
Remove #define for bfd_get_mtime. Remove gratuitous comment.
* bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
BUG: archive members still do not get correct mod times.
Improve floating point support for core files.
* sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
(sunos4_core_file_p): Create a second registers section in the
core file, called ".reg2", for the float registers.
Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
* many changes to improve archive handling; found a logic flaw in
bfd_check_format which only just happened to work by cooncidence.
Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* bfd.c (bfd_perform_relocation): fixed to use output_offsets
correctly.
* bfd.h: changed type of udata in asymbol to void *, like it
should be. Added bfd_reloc_dangerous enum member.
* coff-code.h: Fixed it so that internally generated symbols get
their values relocated correctly in all cases. Removed calls to
xmalloc.
* icoff.c: Not understanding the destination symbol of a reloc is
not a failure any more, just 'dangerous'. This allows linking of
b.out and coff images.
* sunos.c: Cleaned up the way that ZMAGIC section sizes are
calculated.
Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* sunos.c (translate_to_native_sym_flags): fixed
sym_pointer->n_value so that symbols on the way out get their
section relative values calculated correctly.
* coff-code.h (mangle_symbols): fixed problem where tags were not
being relocated for structs, enums, unions. Also various lints.
Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
* archive.c (get_elt_at_filepos): system_call_error returned
incorrectly.
Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
* Resolve the use of no_error and system_call_error.
The bfd library itself now will never set bfd_error to
no_error.
The code still needs to be combed to make sure all the error
codes are correct. I suspect they are not always set correctly.
* The names of all the messages have _ prepended because the sun
bundled compiler can't distinguish from a macro which takes an
argument and the same identifier in a non-macro context.
* The reason for the above being that entry points which used to
be trampoline functions are now just macros which expand to a
direct call through the bfd's xfer vector.
* (../include/intel-coff.h) F_AR32WR: fix this constant. Why
must gas have its own version of everything (the gas version
had the correct value)
Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
properly support i960 architecture and output correct reloc stuff.
* bfd.h: added prototype for bfd_printable_arch_mach, added
BFD_FAIL
* coff-code.h: Applied patches from chrisb to support i960
architecture, zero relocs and swap them correcly and conditionally
compiled the timestamp.
* sunos.c: Made the default section alignment 2^3 so that doubles
are done properly. Fixed the same reloc bug that was in b.out.c
* sysdep.h: Now compiles on a Posix box
Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
* icoff.c: Fix comment on big-endian version.
* coff-code.h: Make HAS_RELOC really work (it's backwards from
F_RELFLG). Set F_AR32WR in output files if little endian
architecture.
Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
* archures.c fixed =/== typo
* sunos.c added architecture stuff for output. Fixed
bug where files where vma(data) != size(text)
were processed wrong.
* coff-code.h added a lint cast
* (../include/a.out.sun4.h) fixed it so zmagic
worked
Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com

table didn't have a null at the end.
* bfd.c fixed includes, added symbols argument to
canonicalize_reloc entry point.

* coff-code.h fixed includes. Added code to support
big and little endian formats. Various lints. Better
processing of symbols. Changed reloc stuff to new
order
* libbfd.h fixed includes
Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
* bfd.h changed name of alignment entry in sec_struct to
alignment_power, because of conflicting uses within bfd.
Now it should be obvious that it's a 2**n alignment
specifier. Removed start_pad, end_alignment, block, minsize,
output_file_alignment, subsection_alignment and original_vma fields.
Added align_power() macro. Fixed bfd_section_alignment
acessor macros. Added bfd_symbol_same_target macro.
* b.out.c (b_out_write_object_contents) fixed to use
new alignment member. Fixed (callj_callback) to use section
relative symbols properly.
* sunos.c (sunos4_object_p) fixed to use new alignment_power.

* b.out.c added callj relocation support, upgrated reloc howto.
Fixed so that asymbol and reloc records are output
correctly.
* bfd.c lots of lint, support for new bfd entry point
bfd_print_symbol.
* bfd.h changed definition of asymbol to contain pointer to
owning bfd, removed target dependencies.
* cache.c took out print statements, put in BFD_ASSERT calls.
* coff-code.h various lints, corrected linenumber output
functionality. Added support for new style asymbols and

pointer lint. Added support for callj relocation. Fixed bug where
the last 32 bytes of the text section were overwritten by data. Fixed bug
where archives of b.out didn't work due bfd_slurp_extended_name_table
returning false.

that it won't be affected by any lengthing of the howto struct typedef.
Various lints

Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl)
* ChangeLog: Started ChangeLog for BFD.
* ToDo: Create file for suggestions.
* Makefile: Support easy loading into Saber C.
Add dependencies for icoff.o and bcs88kcoff.o.
Rename coff.c to coff-code.h. Change callers.
* bfd.c (bfd_check_format): Allow the check_format routines
to return the desired target vector, rather than just a Boolean.
bfd.h (bfd_check_format): Change function pointer return type.
archive.c (bfd_generic_archive_p): change callee.
b.out.c (b_out_little_object_p, b_out_big_object_p,
b_out_real_object_p): change callee.

icoff.c: change callee.
sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
* libbfd.c (zalloc): It should actually zero the storage!
This was commented out for some reason.
* libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
This is so callers can avoid <stdlib.h> which doesn't exist
on older systems.
* bfd.c (map_over_sections): Add debugging code, since I
noticed the section count for sunos core files was bad, but only
GDB had detected the problem.
