3 * reloc.c, section.c, syms.c, targets.c: correct info-node
4 structure in *doc* comments.
5 doc/Makefile: stop hiding complaints from makeinfo.
7 Sun Oct 6 19:10:06 1991 John Gilmore (gnu at cygnus.com)
9 * aoutx.h (...some_aout_object_p): Take a third parameter,
10 the internal_exec struct, and avoid ever looking at an
11 external_exec. All callers changed to read the entire
12 external_exec struct, swap and check its magic number,
13 swap in the whole structure, and pass the swapped-in version to
15 * bout.c: Bring into modern era. Use single _object_p routine
16 for big- aand little-endian. Provide internal and external
17 exec header structs. Use separate swap-in and swap-out routines.
19 * libaout.h: Move struct internal_exec from ../include/aout64.h
20 to here. Add obj_symbol_entry_size to struct aoutdata.
21 * aoutx.h (...some_aout_object_p): Set obj_symbol_entry_size.
23 * ../include/aout64.h: Change EXTERNAL_LIST_SIZE to
24 EXTERNAL_NLIST_SIZE. Callers changed.

33 last byte of transfer, not first byte, is within the section.
35 * host-aout.c: Remove `BSD' archive support. Lint.
37 * archures.c: Rename `struct bfd_arch_info_struct' to `struct
38 bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
39 `bfd_arch_info_type'. All uses changed.
40 * reloc.c: Rename `bfd_reloc_status_enum_type' to
41 `bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
42 to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
43 it needs a better name.) All uses changed.
44 * targets.c: Rename `enum target_flavour_enum' to `enum
45 target_flavour', and remove the `_enum' from all of the enum
46 values themselves. All uses changed.
48 * configure.in, config/h-i386mach: i386 mach host.
49 * config/t-i386-aout: Use host-aout.c.
51 * trad-core.c: Give it its own xvec's to make it independent
52 of other file formats.

61 * cpu-h8300.c: got the registers in the right order
63 Thu Oct 3 19:39:55 1991 John Gilmore (gnu at cygnus.com)
65 * bfd-in.h: enum boolean => enum bfd_boolean for SVR4. Gumby's
66 prediction is vindicated!
68 * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
69 Remove refs to howto.c, since Steve forgot.
71 Thu Oct 3 07:49:21 1991 Steve Chamberlain (steve at cygnus.com)
73 * elf.c: took the abort out of set_arch_mach so that objdump -i will
74 still work. Now allows any architecture/machine to be set.
76 Wed Oct 2 13:50:35 1991 Steve Chamberlain (steve at cygnus.com)
78 * howto.c deleted and moved code to reloc.c
80 * libbfd.h, libbfd-in.h removed $id stuff for real
82 * cpu-h8300.c Made it match various different spellings of h8300.
84 * archures.c: Took out the first char filter which made it only
85 look for a cpu/arch match when the first chars of supplied and
86 tested names were the same.
88 * targets.c removed oasys stuff, pending someone to fix the bugs
92 Tue Oct 1 12:29:44 1991 John Gilmore (gnu at cygnus.com)
94 * Makefile.in, configure.in, targets.c, elf.c: Add preliminary
95 ELF support good enough for GDB.
96 * configure.in, config/h-amix, config/t-m68k-elf: Handle
97 m68k-cbm-svr4 host and target.
98 * config/t-m68k-coff, t-m88k-coff, t-m88k-aout: Make files nonempty
99 so `diff' and `patch' can cope.
101 Tue Oct 1 11:24:31 1991 Steve Chamberlain (steve at cygnus.com)
103 * archures.c: removed texinfo error
105 * init.c: added texinfo hooks, and removed initialization error
108 * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
111 Tue Oct 1 05:02:53 1991 John Gilmore (gnu at cygnus.com)
113 * cpu-i960.c: Avoid numerical count of initializers.
115 Vax Ultrix changes from David Taylor <taylor@think.com>:

121 Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
123 * bfd-in.h VERSION, change version number to 0.18, this makes a
124 gap, but now is the same as the linker version number.
126 * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
127 cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
128 files will eventually contain processor specific bits for bfd,
129 like strange relocation information and dis/assembly. So far only
130 the H8 has been even partially done. This work also ties in with
131 the change in handling architectures.
133 * amdcoff.c: (a29k_reloc) fix error message.
135 * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
136 discover the architecture of the bfd. (sunos4_callback) calls the
137 function bfd_set_arch_mach rather than stuffing stuff directly
138 into the bfd. (sunos4_write_object_contents), changed names of
141 * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
142 setup the environment.
144 * archive.c: (bfd_slurp_coff_armap) coff archives always have the
145 headers in big endian format, regardless of the endianess of the
148 * archures.c: totally changed. Now an architecture is represented
149 with a pointer to an info structure rather than an enumerated type
150 and a long. The old info is available as two elements in the
151 structure. Future enhancements to architecure support will
152 involve pointers to methods being placed into the info structure.
154 * bfd.c: changed the definition of the bfd structure for the new
157 * bout.c: (b_out_set_arch_mach) changed to use the new
158 architecture mechanism.
160 * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
161 the new architecture mechanism.
163 * configure.in: added h8 stuff.
165 * ieee.c: too many changes to note. Now ieee files written with
166 bfd gas and ld can be read by gld and ieee only linkers and
169 * libbfd.c, libbfd.h: changed prototype of bfd_write.
171 * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
172 than fixing the structure directly.
174 * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
175 than fixing the structure directly.
177 * opncls.c: (new_bfd) makes sure that bfd_init has been called
178 before opening a bfd.
180 * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
181 rather than fixing the structure directly.
183 * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
184 in the t/hmake file) a user can select which backends they want
185 linked with bfd without changing the source.
187 * init.c: new, looks after initializing modules.
189 * howto.c: for future use, will allow an application to work out
190 what cookie to use as a handle on a relcoatio howto.
192 Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
194 * srec.c: Better error checking, partly from Peter Schauer.
195 (srec_object_p): Avoid assuming any file that starts with 'S' is
196 an S-record file! (Check for 3 uppercase-hex digits after it.)
197 (ISHEX): Define new macro for checking supposedly hex characters.
198 (pass_over): Treat as EOF any S-record line that:
199 * doesn't have hex in either size character
200 * produces a size larger than 0x7F
201 * has an unrecognized type number
203 Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
205 * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
206 opncls.c: Lint (saber actually).
208 Thu Sep 26 11:24:24 1991 Per Bothner (bothner at cygnus.com)
210 * libaout.h (WRITE_HEADERS): Set header's a_text field always.
211 * newsos3.c: Fixed two types: newos3 -> newsos3.
212 * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
213 to use correct segment.
215 Mon Sep 23 18:24:34 1991 Per Bothner (bothner at cygnus.com)
217 * aoutx.h (print_symbol): Handle missing symbol->name.
219 Fri Sep 20 12:26:01 1991 Stu Grossman (grossman at cygnus.com)
221 * aoutf1.h (swapcore_sparc): Change name of USRSTACK, fix comment
224 Tue Sep 17 17:23:49 1991 Stu Grossman (grossman at cygnus.com)
226 * oasys.c, configure.in, config/h-irix3, config/t-irix3:
227 add sgi/irix support.
229 Thu Sep 12 14:29:09 1991 John Gilmore (gnu at cygint.cygnus.com)
231 Changes for the AMD 29000 Ultracomputer port from David Wood.
234 * opncls.c (bfd_fdopenr): Handle NO_FCNTL.
236 * Makefile.in: Make subdirs work by using $(INCDIR) in the
239 * coffcode.h (coff_real_object_p): Pass information about the
240 current file's coff symbol format to BFD via the coff_data struct.
241 (coff_find_nearest_line): obj_icof => coff_data.
242 (coff_swap_sym_{in,out}): Check that SYMNMLEN == E_SYMNMLEN.
243 (coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
244 and DIMNUM == E_DIMNUM.
245 * configure.in: Handle a29k-*-* hosts, and targets
246 a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
247 * libcoff-in.h: Add local_n_btmask, local_n_btshft,
248 local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
249 local_linesz to `coff_data' (tdata) struct.
250 (coff_data, coff_data_type, coff_tdata): Rename struct icofdata.
251 * config/h-ultra3: Handle a29k-*-* hosts as Ultracomputers.
253 Thu Sep 12 14:07:22 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
255 * Makefile.in: $(MAKE) for make, $(docdir) for doc
256 * doc/Makefile: redundant dependencies for Sun-make VPATH bug
258 Tue Sep 10 20:34:12 1991 John Gilmore (gnu at cygint.cygnus.com)
260 * aoutf1.h (sunos4_core_file_p): Release the right storage in

273 abfd->direction and complain if erroneous.
275 * Makefile.in: Add crude dependencies.
277 Tue Sep 3 13:46:19 1991 Steve Chamberlain (steve at cygint.cygnus.com)
279 * config/* aoutx.h configure* shortened all the h/tmake-xxxx
280 to h/t-xxxx files so that everything will work on System V.
282 Fri Aug 23 13:51:06 1991 John Gilmore (gnu at cygint.cygnus.com)
284 * aoutx.h: Add information on host-aout.c and how to configure
285 to use it, to the manual.
286 * configure.in: Tix typo.
287 * ecoff.c: If compiling for DEC3100, use trad_unix core files,
288 else dummy out the core file support.
289 * trad-core.c (trad_unix_core_file_p): If HOST_DATA_START_ADDR is
290 specified, use it to locate the data section.
291 * coffcode.h (coff_write_symbols): Declare buffer as bfd_bytes
292 rather than as chars (lint).
294 Thu Aug 22 22:20:19 1991 Stu Grossman (grossman at cygint.cygnus.com)

307 * trad-core.c (trad_unix_core_file_p): Use HOST_TEXT_START_ADDR,
308 etc, rather than TEXT_START_ADDR.
309 * host-aout.c: Remove #if 0 around whole thing.
310 Update to modern (32/64-bit) a.out naming conventions.
311 Include a large chunk of ../include/a.out.gnu.h to get macros that
312 are not defined by the system include files.
313 (host_aout_{32,64}_write_object_contents): Use the WRITE_HEADERS
314 macro used by the other a.out implementations.
315 * Makefile.in: Give dependencies to OPTIONAL_BACKENDS.
317 Wed Aug 21 14:33:06 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
319 * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of
320 texdoc and psdoc; make these depend on generated .texi's
322 * scanit, (new) unPROTO: turn PROTO macros into ANSI declarations in
325 * bfd.c, reloc.c, syms.c: minor spelling/wording fixes in doc
328 * Makefile.in, awkscan-ip, awkscan-p, intobfd,

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

393 29k coff by David Wood (wood@lab.ultra.nyu.edu).
395 Thu Jul 4 09:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
397 * Everything: created some new files, core.c format.c, reloc.c,
398 section.c and syms.c to split the functionality a bit better.
399 Cleaned up the rest of the files a bit, and added some
403 Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu)
405 * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl

408 Fri Jun 14 13:19:40 1991 Steve Chamberlain (steve at cygint.cygnus.com)
410 * ../include/bfd.h (struct bfd_target): Added new field
411 "align_power_min" which contains the minimum alignment for a
412 section. This is used in coff_new_section_hook. The field
413 insertion necessitates an update of all backends..
415 * aoutf1.h jump table field inserted
417 * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
420 * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
421 table field inserted.
423 * coffcode.h(just about everything) Now patches up symbol tables
424 using a different mechanism. The Intel major bug has been fixed,
425 and the linker can self host on the Aviion and be debugged with

445 * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
447 * srec.c: now allows any number of sections to be created in a
448 file. Outputs addresses of the right length.
450 Thu May 30 15:30:10 1991 Steve Chamberlain (steve at cygint.cygnus.com)
452 * bfd.c (bfd_check_format): Fixed problem where when a defaulted
453 target didn't match, the format got set to the attempted match,
454 breaking a future test.
456 *../include/i386coff.h : fixed typo in type field with size
458 * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
459 support in the jump table for the swapping routines exported to
460 gdb. Now gdb works with the 386.
462 Tue May 28 17:21:43 1991 John Gilmore (gnu at cygint.cygnus.com)
464 * Merge in changes from gdb-3.95 release.
465 Makefile.in: Allow hmake and tmake files to add OFILES.
467 bfd.c: support specific targets as well as searching. When
468 searching, take default target in preference to others.
470 ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
471 liba.out.h: Don't hard-code file offsets; use N_ macros for them.
472 libbfd.h: Support specific targets as well as searching.
473 opncls.c: Support specific targets as well as searching.
474 targets.c: Search is short-circuited if default target matches.
475 liboasys.c, libieee.c: Undo bothner changes that make macros
476 work to the left of assignment, but which depend on the
477 representations of different pointer types being the same.
479 Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
481 * i386coff.c: created.
482 * coffcode.h: added support for 386.
483 * Makefile.in: added support for 386.
484 * ../include/i386coff.h: created

497 Mon May 20 17:12:17 1991 Steve Chamberlain (steve at cygint.cygnus.com)
499 * everything: Removed sysdep.h from bfd.h and put back into files
500 from which it was split out. Now 64 bit version is built with a
501 -DHOST_64_BIT="long long" on the compile line.
504 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
506 Changed all the [get|put][name] routines to use [get|put]_[size
509 Put in support for 64 bit work. Now two versions of bfd may be
510 generated, according to the state of TARGET_64_BIT, one which is
511 32 bit only, and one which is 64/32 bits.
512 Created new back end 'demo64' to test 64 bit functionality.
514 Renamed some files to work on DOS.

528 64bit ized. * demo64.c: 64 bit a.out back end
534 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
536 * libieee.h: Make ieee_data and ieee_ar_data macros usable
537 on LHS of assignment, even when using old compilers.
538 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
539 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
540 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
541 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
542 * targets.c: Add declaration of newsos3_vec.
545 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
547 * aout.c: fixxed some of the problems with filepos calculation.
548 (swap_ext_reloc): fixed problem with creation of relocs.
549 (aout_set_section_contents): fixed filepos problem
551 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
552 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
553 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
554 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
555 cleaned up. (coff_write_object_contents) cleaned up.
557 * ecoff.c: Totally different. Now supports ecoff fully.
559 * icoff.c: fixed problems in relocation callout.
561 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
563 * m68kcoff.c: updated target vector.
565 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
566 choose_reloc_size. (sunos4_write_object_contents) now calls
567 choose_reloc_size so outputs relocs correctly, also calculates the
568 size of the sections correctly.
572 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
574 Merge Per Bothner's changes to modularize BFD a.out a bit.
576 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
577 * ieee.c: Cast enums to int before comparing them, for brain-
579 * coff-code.h: Remove coff_get_section_contents, and use the
582 * aout.c: Derive new module from sunos.c, containing generic
583 support code for all kinds of a.out files.
585 * sunos.c: Remove all code that goes in aout.c. Split out
586 machine dependent followup in sunos4_object_p into
587 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
588 and redefine only the names we CHANGE, not all the names. Drop
589 the little-endian vector, and rename the vector as sunos4 rather
592 * b.out.c: Use aout.c routines for most of the work. Slight
593 changes for the new regime. Remove close_and_cleanup and
594 get_section_contents in favor of generics. New transfer vector
597 * newsos.c: New support for Sony NEWS, another a.out format.
599 * ecoff.c: Remove close_and_cleanup. New tvec regime.
600 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
601 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
603 * opncls.c (bfd_close): Call format-dependent write_contents
604 routine, if writing, before calling target-dependent
605 close_and_cleanup routine (which is now always generic, I think).
606 * srec.c: Use bfd_alloc instead of malloc. Remove
607 close_and_cleanup and move code from it to
608 srec_write_object_contents. Add write_contents to tvec.
609 * targets.c: Remove a.out little vector, replace a.out big
610 vector with SunOS vector. FIXME: Need Vax support again now.
612 * libbfd.h: Add write_contents format-dependent-vector to the
613 bfd_target vector. Supply a generic close_and_cleanup routine.
614 * liba.out.h: Handle the new aout.c split. Add prototypes for
615 all routines defined in aout.c. Rename "sunos" things to "aout"
616 things. Add a few fields where needed for various formats.
617 * Makefile.in: Add aout.c and newsos.c.
619 * archive.c, ieee.c, oasys.c: Lint.
621 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
624 changed forward declaration struct stat; to reduce warnings. Changed
625 comment on bfd_h_<x>_x.
627 * ../include/m68kcoff.h, ../include/intel-coff.h,
628 ../include/m88k-bcs.h
629 Now there are two incarnations of relocs, linenos and syments. One for
630 internal digestion, and one full of char arrays for I/O. The original
631 names have gone to detect errors.
633 * Makefile.in, m68kcoff.c, targets.c
634 Test new structure code with a 68k coff implementaion
636 * coff-code.h, icoff.c, coffswap.c, libcoff.h
637 Fixed all the places where there were problems with the size and
638 alignments of structures on disk and structures in memory. #ifed out
639 all the code in coffswap.c, since it should be done using the target
642 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
644 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
645 multiple reloc command.
647 * sunos.c (sunos4_set_section_contents): Made it so that sections
648 are always padded to their alignment size.
650 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
652 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
653 Clean up types and such (saber C problems).
654 * ecoff.c: Clean up types and such. Remove routines that are
655 not used. Fix up reading and swapping of shorts from files.
657 Notes on bfd-0.5.2-patch1a, from Per Bothner:
659 * a.out.vax.c: Remove two bogus "static" from prototypes.
661 * ecoff.c: Got rid of lots of non-working junk (that had
662 been copied directly from coff-code.h).
663 Updated to be consistent with updates to icoff.c and coff-code.h.
665 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
666 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
668 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
669 but until the target_vector is automatically generated,
670 it's as good as any. Note that the text offset is the only
671 difference between NewsOS and SunOs (including magic numbers).
672 (Most of the sunos_* routines should to renamed bsd_*
673 and move to a bsd.c file. Then (and when the target_vector
674 is automatically generated) it might make sense to create
675 a separate Sony target.)
677 * sysdep.h: Don't declare fread and fwrite. Causes trouble
678 on some systems, and doesn't help on others.
679 Similarly, only define X_OK if not already defined.
681 * trad-core.c: Don't include sys/stat.h - at least
682 on NewsOS 3, it has already been included.
684 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
686 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
687 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
688 symbol tables if necessary when reading them in, so gdb can use
689 them. Add "bfd_coff_" to the names so they won't conflict with
690 names in calling programs. FIXME-soon: if coff-code.h is
691 included in two BFD modules, this will cause duplicate
692 definitions; the routines should be exported to a separate,
693 common, module (probably along with a mess of other ones).
695 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
697 Improve modtime support.
699 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
700 Remove #define for bfd_get_mtime. Remove gratuitous comment.
701 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
702 BUG: archive members still do not get correct mod times.
704 Improve floating point support for core files.
706 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
707 (sunos4_core_file_p): Create a second registers section in the
708 core file, called ".reg2", for the float registers.
710 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
712 * many changes to improve archive handling; found a logic flaw in
713 bfd_check_format which only just happened to work by cooncidence.
715 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
717 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
720 * bfd.h: changed type of udata in asymbol to void *, like it
721 should be. Added bfd_reloc_dangerous enum member.
723 * coff-code.h: Fixed it so that internally generated symbols get
724 their values relocated correctly in all cases. Removed calls to
727 * icoff.c: Not understanding the destination symbol of a reloc is
728 not a failure any more, just 'dangerous'. This allows linking of
729 b.out and coff images.
731 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
735 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
737 * sunos.c (translate_to_native_sym_flags): fixed
738 sym_pointer->n_value so that symbols on the way out get their
739 section relative values calculated correctly.
741 * coff-code.h (mangle_symbols): fixed problem where tags were not
742 being relocated for structs, enums, unions. Also various lints.
744 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
746 * archive.c (get_elt_at_filepos): system_call_error returned
749 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
751 * Resolve the use of no_error and system_call_error.
752 The bfd library itself now will never set bfd_error to
755 The code still needs to be combed to make sure all the error
756 codes are correct. I suspect they are not always set correctly.
758 * The names of all the messages have _ prepended because the sun
759 bundled compiler can't distinguish from a macro which takes an
760 argument and the same identifier in a non-macro context.
762 * The reason for the above being that entry points which used to
763 be trampoline functions are now just macros which expand to a
764 direct call through the bfd's xfer vector.
766 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
767 must gas have its own version of everything (the gas version
768 had the correct value)
770 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
772 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
773 properly support i960 architecture and output correct reloc stuff.
775 * bfd.h: added prototype for bfd_printable_arch_mach, added
778 * coff-code.h: Applied patches from chrisb to support i960
779 architecture, zero relocs and swap them correcly and conditionally
780 compiled the timestamp.
782 * sunos.c: Made the default section alignment 2^3 so that doubles
783 are done properly. Fixed the same reloc bug that was in b.out.c
785 * sysdep.h: Now compiles on a Posix box
787 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
789 * icoff.c: Fix comment on big-endian version.
790 * coff-code.h: Make HAS_RELOC really work (it's backwards from
791 F_RELFLG). Set F_AR32WR in output files if little endian
794 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
796 * archures.c fixed =/== typo
798 * sunos.c added architecture stuff for output. Fixed
799 bug where files where vma(data) != size(text)
800 were processed wrong.
802 * coff-code.h added a lint cast
804 * (../include/a.out.sun4.h) fixed it so zmagic
807 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
809 * archive.c removed loads of includes, and fixed bug where string
810 table didn't have a null at the end.
812 * bfd.c fixed includes, added symbols argument to
813 canonicalize_reloc entry point.
815 * libbfd.c fixed includes and added some lint patches.
817 * targets.c added both sorts of intel coff.
819 * b.out.c fixed included, changed was the canonical
822 * icoff.c added support for callj and big and little
825 * opncls.c added chmod+xing for files with EXEC_P set.
827 * sunos.c fixed includes. Changed default section
828 alignement to words. Fixed relocation stuff to work with
831 * bfd.h various new types added, prototype for new
832 reloc calls, changed bfd->iostream to a void *
833 to including files don't need stdio.h.
835 * libcoff.h added conversion table to tie relocs to
840 * coff-code.h fixed includes. Added code to support
841 big and little endian formats. Various lints. Better
842 processing of symbols. Changed reloc stuff to new
845 * libbfd.h fixed includes
848 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
850 * bfd.h changed name of alignment entry in sec_struct to
851 alignment_power, because of conflicting uses within bfd.
852 Now it should be obvious that it's a 2**n alignment
853 specifier. Removed start_pad, end_alignment, block, minsize,
854 output_file_alignment, subsection_alignment and original_vma fields.
855 Added align_power() macro. Fixed bfd_section_alignment
856 acessor macros. Added bfd_symbol_same_target macro.
858 * b.out.c (b_out_write_object_contents) fixed to use
859 new alignment member. Fixed (callj_callback) to use section
860 relative symbols properly.
862 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
863 Fixed (translate_from_native_sym_flags) to correctly make
864 symbols section relative.
866 * bfd.c (bfd_errmsg) fixed various enum cast problems.
867 (bfd_make_section) took out initialization of obsolete members.
868 (bfd_print_symbol_vandf) added
870 * opncls.c (bfd_create) created.
872 * coff-code.h (coff_new_section_hook) took away refs
873 to obsolete members. (make_a_section_from_file) added
874 conversion between alignment types. (coff_symbol_from)
875 added. (coff_count_linenumbers) only counts linenumbers
876 if symbol is of coff-type. (coff_mangle_symbols) only
877 heavily mangles symbols if symbol is coff-type.
878 (coff_write_symbols) various lints. (coff_write_object_contents)
879 various lints and modification for alignment conversion.
880 (coff_slurp_relocs) fixed for use with new asection shape.
882 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
884 * archive.c lots of lint
886 * b.out.c added callj relocation support, upgrated reloc howto.
887 Fixed so that asymbol and reloc records are output
890 * bfd.c lots of lint, support for new bfd entry point
893 * bfd.h changed definition of asymbol to contain pointer to
894 owning bfd, removed target dependencies.
896 * cache.c took out print statements, put in BFD_ASSERT calls.
898 * coff-code.h various lints, corrected linenumber output
899 functionality. Added support for new style asymbols and
900 bfd_print_symbol. Fixed so that asymbol and
901 reloc records are handled correctly. Added timestamp.
903 * icoff.c Added support for new howto shape.

914 and bfd_print_symbol.
916 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
918 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
919 pointer lint. Added support for callj relocation. Fixed bug where
920 the last 32 bytes of the text section were overwritten by data. Fixed bug
921 where archives of b.out didn't work due bfd_slurp_extended_name_table
924 * sunos.c added support for n_other field. Braced the howto table so
925 that it won't be affected by any lengthing of the howto struct typedef.
928 * bfd.h added support for n_other field, added special_function
929 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
932 * bfd.c upgraded bfd_perform_relocation, various lints.
934 Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl)

937 * ToDo: Create file for suggestions.
939 * Makefile: Support easy loading into Saber C.
940 Add dependencies for icoff.o and bcs88kcoff.o.
941 Rename coff.c to coff-code.h. Change callers.
943 * bfd.c (bfd_check_format): Allow the check_format routines
944 to return the desired target vector, rather than just a Boolean.
945 bfd.h (bfd_check_format): Change function pointer return type.
946 archive.c (bfd_generic_archive_p): change callee.
947 b.out.c (b_out_little_object_p, b_out_big_object_p,
948 b_out_real_object_p): change callee.
949 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
950 in check_format transfer vectors that need a filler.
951 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
952 bcs88kcoff.c: change callee.
953 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
954 icoff.c: change callee.
955 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
957 * libbfd.c (zalloc): It should actually zero the storage!
958 This was commented out for some reason.
960 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
961 This is so callers can avoid <stdlib.h> which doesn't exist
964 * bfd.c (map_over_sections): Add debugging code, since I
965 noticed the section count for sunos core files was bad, but only
966 GDB had detected the problem.
967 (bfd_set_section_lineno_size, bfd_set_section_linenos,
968 bfd_get_section_linenos): Remove obsolete functions.
969 (bfd_apply_relocations): Use longs, not ints, for the math.
971 * bfd.h: Declare enum boolean and struct bfd_target as well
972 as typedefs for them. Remove obsolete
973 bfd_get_section_lineno_size.
975 * cache.c: Make the "fdopen" support work. Keep better track
976 of how many files are open. Centralize the opening of files
977 and be sure bfd_open[rw] actually try to open the file. Evade
978 linked list initialization problems.
980 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
982 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
984 * cplus-dem.c: Delete file, since it is not part of BFD.
986 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
987 (bfd_openr, bfd_openw): Actually open the file, give error now.
989 * sunos.c (sunos4_core_file_p): Set section count.
990 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
991 obsolete definitions.
992 (_write_symbol_table): Initialize <idx> counter.
