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.
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.
* Patches from Minh Tran-le <mtranle@paris.intellicorp.com>.
* configure.in (i386-*-isc*, i386-*-aix*): New targets.
* configure.host (i386-*-isc*, i386-*-aix*): New hosts.
* hosts/i386isc.h, config/i386isc.mh: New files for Interactive
Unix.
* hosts/i386aix.h, config/i386aix.mh: New files for AIX on PS/2.
* aix386-core.c: New file for handling core files on AIX on PS/2.
* targets.c: if AIX386_CORE, use aix386_core_vec.
* coffcode.h (coff_real_object_p): check for I386SVMAGIC as well
as I386MAGIC.
application. Some of the linker flags ought to get moved to this field
someday.
archures.c (bfd_default_scan): Recognize a few more numbers: 80486, 80960,
and 960.
bfd-in.h, bfd.c, targets.c, coffcode.h, coff-mips.c, other targets: Moved COFF
swap table to backend data.
hosts/i386linux.h: Include unistd.h.
aoutx.h, libaout.h, stab-syms.c: stab names are now in constant storage.
trad-core.c: Fixed some `PARAMS' uses that were missing parentheses.
aoutx.h, archive.c, archures.c, coffcode.h, ctor.c, reloc.c, syms.c: Doc fixes.
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.
* section.c: New section bit SEC_SHARED_LIBRARY.
coffcode.h (styp_to_sec_flags): if STYP_NOLOAD && (STYP_TEXT ||
STYP_DATA), set SEC_SHARED_LIBRARY. This seems to be correct for
i386-sysv.
Tue Oct 27 12:24:34 1992 Ian Lance Taylor (ian@cygnus.com)
* coffcode.h (coff_swap_aux_out): set the fcnary info before
optionally setting the dimen info, since they are in the same
memory locations. Also zero out external auxent.
(coff_write_symbol): don't zero external auxent; now done in
coff_swap_aux_out.
* seclet.c (rel): don't load sections without the SEC_LOAD bit.
Thu Oct 15 10:16:35 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* coff-m68k.c (m68k_howto2type, SELECT_RELOC): new function to
work out a coff relocation type from a howto's attributes rather
than using the input r_type field. This fixes PR1677 and allows
conversion of a.out relocs to coff relocs.
* coffcode.h (coff_write_relocs): if supplied a relocation
relative to an absolute symbol, use the right symbol index.
* reloc.c (bfd_perform_relocation): do a partial link for coff
relocs right.
* changes to support i386-sysv with shared libraries:
* coffcode.h (sec_to_styp_flags): if TWO_DATA_SECS is defined,
check for .data2; if _LIB is defined, check for it; map
SEC_NEVER_LOAD to STYP_NOLOAD.
(styp_to_sec_flags): map STYP_NOLOAD to SEC_NEVER_LOAD.
(make_a_section_from_file): if TWO_DATA_SECS, accept .data2.
(coff_write_object_contents): force vaddr of .lib to 0; set scnptr
if section has contents, not just if it is loadable; if
TWO_DATA_SECS, check for .data2
(coff_set_section_contents): set vma of .lib section to number of
.lib sections.
* coff-i386.c: define TWO_DATA_SECS; use a special CALC_ADDEND;
don't define coff_write_armap to bsd_write_armap.
* hosts/i386v.h: don't include <utime.h>, since it is not provided
by SVR3.2.
coffcode.h, elf.c, ieee.c, libaout.h, libbfd.c, oasys.c,
sco-core.c: Lint: Second argument of bfd_seek is always file_ptr.
Third argument is SEEK_SET or SEEK_CUR. Result is always 0 or -1.
* Portability fixes from p3:
coffcode.h (coff_write_relocs): removed sanity check until it
works on all targets (per advice from sac).
config/hp9000.mh: new file to define USG.
hppa.c: #undef hppa before the JUMP_TABLE.
hosts/hppahpux.h: #define NATIVE_HPPAHPUX_COMPILER if not
__STDC__.
targets.c (bfd_target_list): if NATIVE_HPPAHPUX_COMPILER, make
local variable target volatile to avoid mysterious bug in
HP9000/700 cc.
* coff-z8k.c: getting closer
* coffcode.h (coff_get_relocated_section_contents): allow
EXTRA_CASES hooks for different arches to provide different reloc
types.
* seclet.h: #ifndef around it to allow multiple inclusion
* srec.c: minor doc fix
* coffcode.h (coff_renumber_symbols): set the last renumbered
symbol pointer to NULL, as expected by coff_write_linenumbers.
(coff_write_relocs): apparently a non-zero addend is OK for reloc
type R_IHCONST used on the 29k.
from a coff file (csym is null), dont deref them
* ieee.c (parse_expression): get the answer right when adding an
abs+(sec+off), (ieee_generic_stat_arch_elt): call ieee_object_p
on elts so that filename is filled in.
Lints for bfd_reloc_code_type->bfd_reloc_code_real_type, and
correct calling of howto special functions and fixes from Raeburn
for gas<>bfdness
* archures.c: nuke bfd_reloc_code_type
* bout.c, cpu-h8300.c, coff-i960.c, coff-m88k.c: special function lint
* coffcode.h (styp_to_sec_flags): STYP_INFO is marked as
SEC_NEVER_LOAD, various other bfdgas newness
* reloc.c->libbfd.h: change protype of bfd_default_reloc_type_lookup
* targets.c: change jump table vector to above
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.
* 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.
out tagndx too.
* aoutx.h (swap_std_reloc_out, swap_ext_reloc_out): use the output
section of a symbol rather than the section of a reffed symbol to
determine the r_index of an emmitted reloc.
"done_lineno" so that a symbol which appears twice in the symbol
table only gets it's linenumbers relocated once. Modifed
(coff_write_native_symbol) and (coff_make_empty_symbol) to make
* aout-target.h: add to vector, call generic_relax
* bfd-in.h: add to vector
* bfd.c: add #define for vector
* bout.c: add to vector, call generic_relax
* coffcode.h: add to vector, also now has coff specific relax code
for the relaxable H8/300 relocs. Also clean up abs section cruft.
* elf.c: call generic_relax
* ieee.c: call new vector, clean up some bugs due to the creation
of bfd_abs_section

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
* 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.
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.
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.
* 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.c: Added macros to enable gas to swap coff records.
* coffcode.h: Make the coff_swap_*_out routines return the number
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
* 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
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).
