8 last byte of transfer, not first byte, is within the section.
10 * host-aout.c: Remove `BSD' archive support. Lint.
12 * archures.c: Rename `struct bfd_arch_info_struct' to `struct
13 bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
14 `bfd_arch_info_type'. All uses changed.
15 * reloc.c: Rename `bfd_reloc_status_enum_type' to
16 `bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
17 to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
18 it needs a better name.) All uses changed.
19 * targets.c: Rename `enum target_flavour_enum' to `enum
20 target_flavour', and remove the `_enum' from all of the enum
21 values themselves. All uses changed.
23 * configure.in, config/h-i386mach: i386 mach host.
24 * config/t-i386-aout: Use host-aout.c.
26 * trad-core.c: Give it its own xvec's to make it independent
27 of other file formats.

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

96 Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
98 * bfd-in.h VERSION, change version number to 0.18, this makes a
99 gap, but now is the same as the linker version number.
101 * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
102 cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
103 files will eventually contain processor specific bits for bfd,
104 like strange relocation information and dis/assembly. So far only
105 the H8 has been even partially done. This work also ties in with
106 the change in handling architectures.
108 * amdcoff.c: (a29k_reloc) fix error message.
110 * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
111 discover the architecture of the bfd. (sunos4_callback) calls the
112 function bfd_set_arch_mach rather than stuffing stuff directly
113 into the bfd. (sunos4_write_object_contents), changed names of
116 * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
117 setup the environment.
119 * archive.c: (bfd_slurp_coff_armap) coff archives always have the
120 headers in big endian format, regardless of the endianess of the
123 * archures.c: totally changed. Now an architecture is represented
124 with a pointer to an info structure rather than an enumerated type
125 and a long. The old info is available as two elements in the
126 structure. Future enhancements to architecure support will
127 involve pointers to methods being placed into the info structure.
129 * bfd.c: changed the definition of the bfd structure for the new
132 * bout.c: (b_out_set_arch_mach) changed to use the new
133 architecture mechanism.
135 * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
136 the new architecture mechanism.
138 * configure.in: added h8 stuff.
140 * ieee.c: too many changes to note. Now ieee files written with
141 bfd gas and ld can be read by gld and ieee only linkers and
144 * libbfd.c, libbfd.h: changed prototype of bfd_write.
146 * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
147 than fixing the structure directly.
149 * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
150 than fixing the structure directly.
152 * opncls.c: (new_bfd) makes sure that bfd_init has been called
153 before opening a bfd.
155 * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
156 rather than fixing the structure directly.
158 * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
159 in the t/hmake file) a user can select which backends they want
160 linked with bfd without changing the source.
162 * init.c: new, looks after initializing modules.
164 * howto.c: for future use, will allow an application to work out
165 what cookie to use as a handle on a relcoatio howto.
167 Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
169 * srec.c: Better error checking, partly from Peter Schauer.
170 (srec_object_p): Avoid assuming any file that starts with 'S' is
171 an S-record file! (Check for 3 uppercase-hex digits after it.)
172 (ISHEX): Define new macro for checking supposedly hex characters.
173 (pass_over): Treat as EOF any S-record line that:
174 * doesn't have hex in either size character
175 * produces a size larger than 0x7F
176 * has an unrecognized type number
178 Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
180 * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
181 opncls.c: Lint (saber actually).
183 Thu Sep 26 11:24:24 1991 Per Bothner (bothner at cygnus.com)
185 * libaout.h (WRITE_HEADERS): Set header's a_text field always.
186 * newsos3.c: Fixed two types: newos3 -> newsos3.
187 * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
188 to use correct segment.
190 Mon Sep 23 18:24:34 1991 Per Bothner (bothner at cygnus.com)
192 * aoutx.h (print_symbol): Handle missing symbol->name.
194 Fri Sep 20 12:26:01 1991 Stu Grossman (grossman at cygnus.com)
196 * aoutf1.h (swapcore_sparc): Change name of USRSTACK, fix comment
199 Tue Sep 17 17:23:49 1991 Stu Grossman (grossman at cygnus.com)
201 * oasys.c, configure.in, config/h-irix3, config/t-irix3:
202 add sgi/irix support.
204 Thu Sep 12 14:29:09 1991 John Gilmore (gnu at cygint.cygnus.com)

209 * opncls.c (bfd_fdopenr): Handle NO_FCNTL.
211 * Makefile.in: Make subdirs work by using $(INCDIR) in the
214 * coffcode.h (coff_real_object_p): Pass information about the
215 current file's coff symbol format to BFD via the coff_data struct.
216 (coff_find_nearest_line): obj_icof => coff_data.
217 (coff_swap_sym_{in,out}): Check that SYMNMLEN == E_SYMNMLEN.
218 (coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
219 and DIMNUM == E_DIMNUM.
220 * configure.in: Handle a29k-*-* hosts, and targets
221 a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
222 * libcoff-in.h: Add local_n_btmask, local_n_btshft,
223 local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
224 local_linesz to `coff_data' (tdata) struct.
225 (coff_data, coff_data_type, coff_tdata): Rename struct icofdata.
226 * config/h-ultra3: Handle a29k-*-* hosts as Ultracomputers.
228 Thu Sep 12 14:07:22 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
230 * Makefile.in: $(MAKE) for make, $(docdir) for doc
231 * doc/Makefile: redundant dependencies for Sun-make VPATH bug

254 * config/* aoutx.h configure* shortened all the h/tmake-xxxx
255 to h/t-xxxx files so that everything will work on System V.
257 Fri Aug 23 13:51:06 1991 John Gilmore (gnu at cygint.cygnus.com)
259 * aoutx.h: Add information on host-aout.c and how to configure
260 to use it, to the manual.
261 * configure.in: Tix typo.

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

372 * Everything: created some new files, core.c format.c, reloc.c,
373 section.c and syms.c to split the functionality a bit better.
374 Cleaned up the rest of the files a bit, and added some
378 Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu)

385 * ../include/bfd.h (struct bfd_target): Added new field
386 "align_power_min" which contains the minimum alignment for a
387 section. This is used in coff_new_section_hook. The field
388 insertion necessitates an update of all backends..
390 * aoutf1.h jump table field inserted
392 * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
395 * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
396 table field inserted.
398 * coffcode.h(just about everything) Now patches up symbol tables
399 using a different mechanism. The Intel major bug has been fixed,

422 * srec.c: now allows any number of sections to be created in a
423 file. Outputs addresses of the right length.
425 Thu May 30 15:30:10 1991 Steve Chamberlain (steve at cygint.cygnus.com)
427 * bfd.c (bfd_check_format): Fixed problem where when a defaulted
428 target didn't match, the format got set to the attempted match,
429 breaking a future test.
431 *../include/i386coff.h : fixed typo in type field with size
433 * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
434 support in the jump table for the swapping routines exported to
435 gdb. Now gdb works with the 386.
437 Tue May 28 17:21:43 1991 John Gilmore (gnu at cygint.cygnus.com)
439 * Merge in changes from gdb-3.95 release.
440 Makefile.in: Allow hmake and tmake files to add OFILES.
442 bfd.c: support specific targets as well as searching. When
443 searching, take default target in preference to others.
445 ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
446 liba.out.h: Don't hard-code file offsets; use N_ macros for them.
447 libbfd.h: Support specific targets as well as searching.
448 opncls.c: Support specific targets as well as searching.
449 targets.c: Search is short-circuited if default target matches.
450 liboasys.c, libieee.c: Undo bothner changes that make macros
451 work to the left of assignment, but which depend on the
452 representations of different pointer types being the same.
454 Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
456 * i386coff.c: created.

475 from which it was split out. Now 64 bit version is built with a
476 -DHOST_64_BIT="long long" on the compile line.
479 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
481 Changed all the [get|put][name] routines to use [get|put]_[size
484 Put in support for 64 bit work. Now two versions of bfd may be
485 generated, according to the state of TARGET_64_BIT, one which is
486 32 bit only, and one which is 64/32 bits.
487 Created new back end 'demo64' to test 64 bit functionality.
489 Renamed some files to work on DOS.

502 be called b.out.c * coffcode.h: used to be called coff-code.h, now
503 64bit ized. * demo64.c: 64 bit a.out back end
509 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
511 * libieee.h: Make ieee_data and ieee_ar_data macros usable
512 on LHS of assignment, even when using old compilers.
513 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
514 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
515 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
516 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
517 * targets.c: Add declaration of newsos3_vec.
520 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
522 * aout.c: fixxed some of the problems with filepos calculation.
523 (swap_ext_reloc): fixed problem with creation of relocs.
524 (aout_set_section_contents): fixed filepos problem
526 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
527 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
528 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
529 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
530 cleaned up. (coff_write_object_contents) cleaned up.
532 * ecoff.c: Totally different. Now supports ecoff fully.
534 * icoff.c: fixed problems in relocation callout.
536 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
538 * m68kcoff.c: updated target vector.
540 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
541 choose_reloc_size. (sunos4_write_object_contents) now calls
542 choose_reloc_size so outputs relocs correctly, also calculates the
543 size of the sections correctly.
547 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
549 Merge Per Bothner's changes to modularize BFD a.out a bit.
551 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
552 * ieee.c: Cast enums to int before comparing them, for brain-
554 * coff-code.h: Remove coff_get_section_contents, and use the
557 * aout.c: Derive new module from sunos.c, containing generic
558 support code for all kinds of a.out files.
560 * sunos.c: Remove all code that goes in aout.c. Split out
561 machine dependent followup in sunos4_object_p into
562 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
563 and redefine only the names we CHANGE, not all the names. Drop
564 the little-endian vector, and rename the vector as sunos4 rather
567 * b.out.c: Use aout.c routines for most of the work. Slight
568 changes for the new regime. Remove close_and_cleanup and
569 get_section_contents in favor of generics. New transfer vector
572 * newsos.c: New support for Sony NEWS, another a.out format.
574 * ecoff.c: Remove close_and_cleanup. New tvec regime.
575 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
576 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
578 * opncls.c (bfd_close): Call format-dependent write_contents
579 routine, if writing, before calling target-dependent
580 close_and_cleanup routine (which is now always generic, I think).
581 * srec.c: Use bfd_alloc instead of malloc. Remove
582 close_and_cleanup and move code from it to
583 srec_write_object_contents. Add write_contents to tvec.
584 * targets.c: Remove a.out little vector, replace a.out big
585 vector with SunOS vector. FIXME: Need Vax support again now.
587 * libbfd.h: Add write_contents format-dependent-vector to the
588 bfd_target vector. Supply a generic close_and_cleanup routine.
589 * liba.out.h: Handle the new aout.c split. Add prototypes for
590 all routines defined in aout.c. Rename "sunos" things to "aout"
591 things. Add a few fields where needed for various formats.
592 * Makefile.in: Add aout.c and newsos.c.
594 * archive.c, ieee.c, oasys.c: Lint.
596 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
599 changed forward declaration struct stat; to reduce warnings. Changed
600 comment on bfd_h_<x>_x.
602 * ../include/m68kcoff.h, ../include/intel-coff.h,
603 ../include/m88k-bcs.h
604 Now there are two incarnations of relocs, linenos and syments. One for
605 internal digestion, and one full of char arrays for I/O. The original
606 names have gone to detect errors.
608 * Makefile.in, m68kcoff.c, targets.c
609 Test new structure code with a 68k coff implementaion
611 * coff-code.h, icoff.c, coffswap.c, libcoff.h
612 Fixed all the places where there were problems with the size and
613 alignments of structures on disk and structures in memory. #ifed out
614 all the code in coffswap.c, since it should be done using the target
617 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
619 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
620 multiple reloc command.
622 * sunos.c (sunos4_set_section_contents): Made it so that sections
623 are always padded to their alignment size.
625 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
627 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
628 Clean up types and such (saber C problems).
629 * ecoff.c: Clean up types and such. Remove routines that are
630 not used. Fix up reading and swapping of shorts from files.
632 Notes on bfd-0.5.2-patch1a, from Per Bothner:
634 * a.out.vax.c: Remove two bogus "static" from prototypes.
636 * ecoff.c: Got rid of lots of non-working junk (that had
637 been copied directly from coff-code.h).
638 Updated to be consistent with updates to icoff.c and coff-code.h.
640 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
641 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
643 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
644 but until the target_vector is automatically generated,
645 it's as good as any. Note that the text offset is the only
646 difference between NewsOS and SunOs (including magic numbers).
647 (Most of the sunos_* routines should to renamed bsd_*
648 and move to a bsd.c file. Then (and when the target_vector
649 is automatically generated) it might make sense to create
650 a separate Sony target.)
652 * sysdep.h: Don't declare fread and fwrite. Causes trouble
653 on some systems, and doesn't help on others.
654 Similarly, only define X_OK if not already defined.
656 * trad-core.c: Don't include sys/stat.h - at least
657 on NewsOS 3, it has already been included.
659 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
661 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
662 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
663 symbol tables if necessary when reading them in, so gdb can use
664 them. Add "bfd_coff_" to the names so they won't conflict with
665 names in calling programs. FIXME-soon: if coff-code.h is
666 included in two BFD modules, this will cause duplicate
667 definitions; the routines should be exported to a separate,
668 common, module (probably along with a mess of other ones).
670 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
672 Improve modtime support.
674 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
675 Remove #define for bfd_get_mtime. Remove gratuitous comment.
676 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
677 BUG: archive members still do not get correct mod times.
679 Improve floating point support for core files.
681 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
682 (sunos4_core_file_p): Create a second registers section in the
683 core file, called ".reg2", for the float registers.
685 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
687 * many changes to improve archive handling; found a logic flaw in
688 bfd_check_format which only just happened to work by cooncidence.
690 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
692 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
695 * bfd.h: changed type of udata in asymbol to void *, like it
696 should be. Added bfd_reloc_dangerous enum member.
698 * coff-code.h: Fixed it so that internally generated symbols get
699 their values relocated correctly in all cases. Removed calls to
702 * icoff.c: Not understanding the destination symbol of a reloc is
703 not a failure any more, just 'dangerous'. This allows linking of
704 b.out and coff images.
706 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
710 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
712 * sunos.c (translate_to_native_sym_flags): fixed
713 sym_pointer->n_value so that symbols on the way out get their
714 section relative values calculated correctly.
716 * coff-code.h (mangle_symbols): fixed problem where tags were not
717 being relocated for structs, enums, unions. Also various lints.
719 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
721 * archive.c (get_elt_at_filepos): system_call_error returned
724 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
726 * Resolve the use of no_error and system_call_error.
727 The bfd library itself now will never set bfd_error to
730 The code still needs to be combed to make sure all the error
731 codes are correct. I suspect they are not always set correctly.
733 * The names of all the messages have _ prepended because the sun
734 bundled compiler can't distinguish from a macro which takes an
735 argument and the same identifier in a non-macro context.
737 * The reason for the above being that entry points which used to
738 be trampoline functions are now just macros which expand to a
739 direct call through the bfd's xfer vector.
741 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
742 must gas have its own version of everything (the gas version
743 had the correct value)
745 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
747 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
748 properly support i960 architecture and output correct reloc stuff.
750 * bfd.h: added prototype for bfd_printable_arch_mach, added
753 * coff-code.h: Applied patches from chrisb to support i960
754 architecture, zero relocs and swap them correcly and conditionally
755 compiled the timestamp.
757 * sunos.c: Made the default section alignment 2^3 so that doubles
758 are done properly. Fixed the same reloc bug that was in b.out.c
760 * sysdep.h: Now compiles on a Posix box
762 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
764 * icoff.c: Fix comment on big-endian version.
765 * coff-code.h: Make HAS_RELOC really work (it's backwards from
766 F_RELFLG). Set F_AR32WR in output files if little endian
769 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
771 * archures.c fixed =/== typo
773 * sunos.c added architecture stuff for output. Fixed
774 bug where files where vma(data) != size(text)
775 were processed wrong.
777 * coff-code.h added a lint cast
779 * (../include/a.out.sun4.h) fixed it so zmagic
782 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
784 * archive.c removed loads of includes, and fixed bug where string
785 table didn't have a null at the end.
787 * bfd.c fixed includes, added symbols argument to
788 canonicalize_reloc entry point.
790 * libbfd.c fixed includes and added some lint patches.
792 * targets.c added both sorts of intel coff.
794 * b.out.c fixed included, changed was the canonical
797 * icoff.c added support for callj and big and little
800 * opncls.c added chmod+xing for files with EXEC_P set.
802 * sunos.c fixed includes. Changed default section
803 alignement to words. Fixed relocation stuff to work with
806 * bfd.h various new types added, prototype for new
807 reloc calls, changed bfd->iostream to a void *
808 to including files don't need stdio.h.
810 * libcoff.h added conversion table to tie relocs to
815 * coff-code.h fixed includes. Added code to support
816 big and little endian formats. Various lints. Better
817 processing of symbols. Changed reloc stuff to new
820 * libbfd.h fixed includes
823 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
825 * bfd.h changed name of alignment entry in sec_struct to
826 alignment_power, because of conflicting uses within bfd.
827 Now it should be obvious that it's a 2**n alignment
828 specifier. Removed start_pad, end_alignment, block, minsize,
829 output_file_alignment, subsection_alignment and original_vma fields.
830 Added align_power() macro. Fixed bfd_section_alignment
831 acessor macros. Added bfd_symbol_same_target macro.
833 * b.out.c (b_out_write_object_contents) fixed to use
834 new alignment member. Fixed (callj_callback) to use section
835 relative symbols properly.
837 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
838 Fixed (translate_from_native_sym_flags) to correctly make
839 symbols section relative.
841 * bfd.c (bfd_errmsg) fixed various enum cast problems.
842 (bfd_make_section) took out initialization of obsolete members.
843 (bfd_print_symbol_vandf) added
845 * opncls.c (bfd_create) created.
847 * coff-code.h (coff_new_section_hook) took away refs
848 to obsolete members. (make_a_section_from_file) added
849 conversion between alignment types. (coff_symbol_from)
850 added. (coff_count_linenumbers) only counts linenumbers
851 if symbol is of coff-type. (coff_mangle_symbols) only
852 heavily mangles symbols if symbol is coff-type.
853 (coff_write_symbols) various lints. (coff_write_object_contents)
854 various lints and modification for alignment conversion.
855 (coff_slurp_relocs) fixed for use with new asection shape.
857 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
859 * archive.c lots of lint
861 * b.out.c added callj relocation support, upgrated reloc howto.
862 Fixed so that asymbol and reloc records are output
865 * bfd.c lots of lint, support for new bfd entry point
868 * bfd.h changed definition of asymbol to contain pointer to
869 owning bfd, removed target dependencies.
871 * cache.c took out print statements, put in BFD_ASSERT calls.
873 * coff-code.h various lints, corrected linenumber output
874 functionality. Added support for new style asymbols and
875 bfd_print_symbol. Fixed so that asymbol and
876 reloc records are handled correctly. Added timestamp.
878 * icoff.c Added support for new howto shape.
880 * liba.out.h Added support for new asymbol shape
882 * libbfd.c various lints
884 * libbfd.h various lints
886 * libcoff.h added support for new asymbol shape.
888 * sunos.c various lints. Added support for new asymbol shape
889 and bfd_print_symbol.
891 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
893 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
894 pointer lint. Added support for callj relocation. Fixed bug where
895 the last 32 bytes of the text section were overwritten by data. Fixed bug
896 where archives of b.out didn't work due bfd_slurp_extended_name_table
899 * sunos.c added support for n_other field. Braced the howto table so
900 that it won't be affected by any lengthing of the howto struct typedef.
903 * bfd.h added support for n_other field, added special_function
904 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
907 * bfd.c upgraded bfd_perform_relocation, various lints.
909 Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl)
911 * ChangeLog: Started ChangeLog for BFD.
912 * ToDo: Create file for suggestions.
914 * Makefile: Support easy loading into Saber C.
915 Add dependencies for icoff.o and bcs88kcoff.o.
916 Rename coff.c to coff-code.h. Change callers.
918 * bfd.c (bfd_check_format): Allow the check_format routines
919 to return the desired target vector, rather than just a Boolean.
920 bfd.h (bfd_check_format): Change function pointer return type.
921 archive.c (bfd_generic_archive_p): change callee.
922 b.out.c (b_out_little_object_p, b_out_big_object_p,
923 b_out_real_object_p): change callee.
924 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
925 in check_format transfer vectors that need a filler.
926 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
927 bcs88kcoff.c: change callee.
928 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
929 icoff.c: change callee.
930 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
932 * libbfd.c (zalloc): It should actually zero the storage!
933 This was commented out for some reason.
935 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
936 This is so callers can avoid <stdlib.h> which doesn't exist
939 * bfd.c (map_over_sections): Add debugging code, since I
940 noticed the section count for sunos core files was bad, but only
941 GDB had detected the problem.
942 (bfd_set_section_lineno_size, bfd_set_section_linenos,
943 bfd_get_section_linenos): Remove obsolete functions.
944 (bfd_apply_relocations): Use longs, not ints, for the math.
946 * bfd.h: Declare enum boolean and struct bfd_target as well
947 as typedefs for them. Remove obsolete
948 bfd_get_section_lineno_size.
950 * cache.c: Make the "fdopen" support work. Keep better track
951 of how many files are open. Centralize the opening of files
952 and be sure bfd_open[rw] actually try to open the file. Evade
953 linked list initialization problems.
955 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
957 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
959 * cplus-dem.c: Delete file, since it is not part of BFD.
961 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
962 (bfd_openr, bfd_openw): Actually open the file, give error now.
964 * sunos.c (sunos4_core_file_p): Set section count.
965 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
966 obsolete definitions.
967 (_write_symbol_table): Initialize <idx> counter.
968 (foop): Eliminate debugging code.
