3 * cpu-i960.c: Avoid numerical count of initializers.
6 * host-aout.c: Make little-endian vector really little-endian.
7 * configure.in: Separate vax and tahoe cases, handle ultrix.
8 * config/t-vax: Add trad-core.o.
9 * config/h-vaxult: New host system.
11 Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
13 * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
14 cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
15 files will eventually contain processor specific bits for bfd,
16 like strange relocation information and dis/assembly. So far only
17 the H8 has been even partially done. This work also ties in with
18 the change in handling architectures.
20 * amdcoff.c: (a29k_reloc) fix error message.
22 * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
23 discover the architecture of the bfd. (sunos4_callback) calls the
24 function bfd_set_arch_mach rather than stuffing stuff directly
25 into the bfd. (sunos4_write_object_contents), changed names of
28 * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
29 setup the environment.
31 * archive.c: (bfd_slurp_coff_armap) coff archives always have the
32 headers in big endian format, regardless of the endianess of the
35 * archures.c: totally changed. Now an architecture is represented
36 with a pointer to an info structure rather than an enumerated type
37 and a long. The old info is available as two elements in the
38 structure. Future enhancements to architecure support will
39 involve pointers to methods being placed into the info structure.
41 * bfd.c: changed the definition of the bfd structure for the new
44 * bout.c: (b_out_set_arch_mach) changed to use the new
45 architecture mechanism.
47 * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
48 the new architecture mechanism.
50 * configure.in: added h8 stuff.
52 * ieee.c: too many changes to note. Now ieee files written with
53 bfd gas and ld can be read by gld and ieee only linkers and
56 * libbfd.c, libbfd.h: changed prototype of bfd_write.
58 * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
59 than fixing the structure directly.
61 * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
62 than fixing the structure directly.
64 * opncls.c: (new_bfd) makes sure that bfd_init has been called
67 * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
68 rather than fixing the structure directly.
70 * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
71 in the t/hmake file) a user can select which backends they want
72 linked with bfd without changing the source.
74 * init.c: new, looks after initializing modules.
76 * howto.c: for future use, will allow an application to work out
77 what cookie to use as a handle on a relcoatio howto.
79 Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
81 * srec.c: Better error checking, partly from Peter Schauer.
82 (srec_object_p): Avoid assuming any file that starts with 'S' is
83 an S-record file! (Check for 3 uppercase-hex digits after it.)
84 (ISHEX): Define new macro for checking supposedly hex characters.
85 (pass_over): Treat as EOF any S-record line that:
86 * doesn't have hex in either size character
87 * produces a size larger than 0x7F
88 * has an unrecognized type number
90 Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
92 * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
93 opncls.c: Lint (saber actually).
95 Thu Sep 26 11:24:24 1991 Per Bothner (bothner at cygnus.com)
97 * libaout.h (WRITE_HEADERS): Set header's a_text field always.
98 * newsos3.c: Fixed two types: newos3 -> newsos3.
99 * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
100 to use correct segment.
102 Mon Sep 23 18:24:34 1991 Per Bothner (bothner at cygnus.com)
104 * aoutx.h (print_symbol): Handle missing symbol->name.
106 Fri Sep 20 12:26:01 1991 Stu Grossman (grossman at cygnus.com)
108 * aoutf1.h (swapcore_sparc): Change name of USRSTACK, fix comment
111 Tue Sep 17 17:23:49 1991 Stu Grossman (grossman at cygnus.com)
113 * oasys.c, configure.in, config/h-irix3, config/t-irix3:
114 add sgi/irix support.
116 Thu Sep 12 14:29:09 1991 John Gilmore (gnu at cygint.cygnus.com)

127 current file's coff symbol format to BFD via the coff_data struct.
128 (coff_find_nearest_line): obj_icof => coff_data.
129 (coff_swap_sym_{in,out}): Check that SYMNMLEN == E_SYMNMLEN.
130 (coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
131 and DIMNUM == E_DIMNUM.
132 * configure.in: Handle a29k-*-* hosts, and targets
133 a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
134 * libcoff-in.h: Add local_n_btmask, local_n_btshft,
135 local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
136 local_linesz to `coff_data' (tdata) struct.
137 (coff_data, coff_data_type, coff_tdata): Rename struct icofdata.
138 * config/h-ultra3: Handle a29k-*-* hosts as Ultracomputers.

172 to use it, to the manual.
173 * configure.in: Tix typo.
174 * ecoff.c: If compiling for DEC3100, use trad_unix core files,
175 else dummy out the core file support.
176 * trad-core.c (trad_unix_core_file_p): If HOST_DATA_START_ADDR is
177 specified, use it to locate the data section.
178 * coffcode.h (coff_write_symbols): Declare buffer as bfd_bytes

194 * trad-core.c (trad_unix_core_file_p): Use HOST_TEXT_START_ADDR,
195 etc, rather than TEXT_START_ADDR.
196 * host-aout.c: Remove #if 0 around whole thing.
197 Update to modern (32/64-bit) a.out naming conventions.
198 Include a large chunk of ../include/a.out.gnu.h to get macros that
199 are not defined by the system include files.
200 (host_aout_{32,64}_write_object_contents): Use the WRITE_HEADERS
201 macro used by the other a.out implementations.
202 * Makefile.in: Give dependencies to OPTIONAL_BACKENDS.
204 Wed Aug 21 14:33:06 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
206 * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of

259 Install header comments and attribute most modules to their
260 authors. BFD's name is now officially "Binary File Descriptor",
261 so remove any conflicting pejoratives.
262 archures.h: Consists solely of comments; remove it.
264 Fri Jul 26 18:11:34 1991 Steve Chamberlain (steve at cygint.cygnus.com)

297 * ../include/bfd.h (struct bfd_target): Added new field
298 "align_power_min" which contains the minimum alignment for a
299 section. This is used in coff_new_section_hook. The field
300 insertion necessitates an update of all backends..
302 * aoutf1.h jump table field inserted
304 * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
307 * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump

334 * srec.c: now allows any number of sections to be created in a
335 file. Outputs addresses of the right length.
337 Thu May 30 15:30:10 1991 Steve Chamberlain (steve at cygint.cygnus.com)
339 * bfd.c (bfd_check_format): Fixed problem where when a defaulted
340 target didn't match, the format got set to the attempted match,
341 breaking a future test.
343 *../include/i386coff.h : fixed typo in type field with size
345 * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
346 support in the jump table for the swapping routines exported to
347 gdb. Now gdb works with the 386.

355 searching, take default target in preference to others.
357 ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
358 liba.out.h: Don't hard-code file offsets; use N_ macros for them.
359 libbfd.h: Support specific targets as well as searching.
360 opncls.c: Support specific targets as well as searching.
361 targets.c: Search is short-circuited if default target matches.
362 liboasys.c, libieee.c: Undo bothner changes that make macros
363 work to the left of assignment, but which depend on the
364 representations of different pointer types being the same.
366 Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
368 * i386coff.c: created.

388 -DHOST_64_BIT="long long" on the compile line.
391 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
393 Changed all the [get|put][name] routines to use [get|put]_[size
396 Put in support for 64 bit work. Now two versions of bfd may be
397 generated, according to the state of TARGET_64_BIT, one which is
398 32 bit only, and one which is 64/32 bits.
399 Created new back end 'demo64' to test 64 bit functionality.

414 be called b.out.c * coffcode.h: used to be called coff-code.h, now
415 64bit ized. * demo64.c: 64 bit a.out back end
421 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
423 * libieee.h: Make ieee_data and ieee_ar_data macros usable
424 on LHS of assignment, even when using old compilers.

448 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
450 * m68kcoff.c: updated target vector.
452 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
453 choose_reloc_size. (sunos4_write_object_contents) now calls
454 choose_reloc_size so outputs relocs correctly, also calculates the
455 size of the sections correctly.
459 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
461 Merge Per Bothner's changes to modularize BFD a.out a bit.

469 * aout.c: Derive new module from sunos.c, containing generic
470 support code for all kinds of a.out files.
472 * sunos.c: Remove all code that goes in aout.c. Split out
473 machine dependent followup in sunos4_object_p into
474 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
475 and redefine only the names we CHANGE, not all the names. Drop
476 the little-endian vector, and rename the vector as sunos4 rather
479 * b.out.c: Use aout.c routines for most of the work. Slight
480 changes for the new regime. Remove close_and_cleanup and

490 * opncls.c (bfd_close): Call format-dependent write_contents
491 routine, if writing, before calling target-dependent
492 close_and_cleanup routine (which is now always generic, I think).
493 * srec.c: Use bfd_alloc instead of malloc. Remove
494 close_and_cleanup and move code from it to
495 srec_write_object_contents. Add write_contents to tvec.
496 * targets.c: Remove a.out little vector, replace a.out big
497 vector with SunOS vector. FIXME: Need Vax support again now.

511 changed forward declaration struct stat; to reduce warnings. Changed
512 comment on bfd_h_<x>_x.
514 * ../include/m68kcoff.h, ../include/intel-coff.h,
515 ../include/m88k-bcs.h
516 Now there are two incarnations of relocs, linenos and syments. One for
517 internal digestion, and one full of char arrays for I/O. The original
518 names have gone to detect errors.
520 * Makefile.in, m68kcoff.c, targets.c
521 Test new structure code with a 68k coff implementaion
523 * coff-code.h, icoff.c, coffswap.c, libcoff.h
524 Fixed all the places where there were problems with the size and
525 alignments of structures on disk and structures in memory. #ifed out
526 all the code in coffswap.c, since it should be done using the target
529 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
531 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
532 multiple reloc command.
534 * sunos.c (sunos4_set_section_contents): Made it so that sections
535 are always padded to their alignment size.
537 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
539 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
540 Clean up types and such (saber C problems).
541 * ecoff.c: Clean up types and such. Remove routines that are
542 not used. Fix up reading and swapping of shorts from files.
544 Notes on bfd-0.5.2-patch1a, from Per Bothner:
546 * a.out.vax.c: Remove two bogus "static" from prototypes.
548 * ecoff.c: Got rid of lots of non-working junk (that had
549 been copied directly from coff-code.h).
550 Updated to be consistent with updates to icoff.c and coff-code.h.
552 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
553 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
555 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
556 but until the target_vector is automatically generated,
557 it's as good as any. Note that the text offset is the only
558 difference between NewsOS and SunOs (including magic numbers).
559 (Most of the sunos_* routines should to renamed bsd_*
560 and move to a bsd.c file. Then (and when the target_vector
561 is automatically generated) it might make sense to create
562 a separate Sony target.)
564 * sysdep.h: Don't declare fread and fwrite. Causes trouble
565 on some systems, and doesn't help on others.
566 Similarly, only define X_OK if not already defined.
568 * trad-core.c: Don't include sys/stat.h - at least
569 on NewsOS 3, it has already been included.
571 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
573 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
574 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
575 symbol tables if necessary when reading them in, so gdb can use
576 them. Add "bfd_coff_" to the names so they won't conflict with
577 names in calling programs. FIXME-soon: if coff-code.h is
578 included in two BFD modules, this will cause duplicate
579 definitions; the routines should be exported to a separate,
580 common, module (probably along with a mess of other ones).
582 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
584 Improve modtime support.
586 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
587 Remove #define for bfd_get_mtime. Remove gratuitous comment.
588 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
589 BUG: archive members still do not get correct mod times.
591 Improve floating point support for core files.
593 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
594 (sunos4_core_file_p): Create a second registers section in the
595 core file, called ".reg2", for the float registers.
597 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
599 * many changes to improve archive handling; found a logic flaw in
600 bfd_check_format which only just happened to work by cooncidence.
602 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
604 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
607 * bfd.h: changed type of udata in asymbol to void *, like it
608 should be. Added bfd_reloc_dangerous enum member.
610 * coff-code.h: Fixed it so that internally generated symbols get
611 their values relocated correctly in all cases. Removed calls to
614 * icoff.c: Not understanding the destination symbol of a reloc is
615 not a failure any more, just 'dangerous'. This allows linking of
616 b.out and coff images.
618 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
622 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
624 * sunos.c (translate_to_native_sym_flags): fixed
625 sym_pointer->n_value so that symbols on the way out get their
626 section relative values calculated correctly.
628 * coff-code.h (mangle_symbols): fixed problem where tags were not
629 being relocated for structs, enums, unions. Also various lints.
631 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
633 * archive.c (get_elt_at_filepos): system_call_error returned
636 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
638 * Resolve the use of no_error and system_call_error.
639 The bfd library itself now will never set bfd_error to
642 The code still needs to be combed to make sure all the error
643 codes are correct. I suspect they are not always set correctly.
645 * The names of all the messages have _ prepended because the sun
646 bundled compiler can't distinguish from a macro which takes an
647 argument and the same identifier in a non-macro context.
649 * The reason for the above being that entry points which used to
650 be trampoline functions are now just macros which expand to a
651 direct call through the bfd's xfer vector.
653 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
654 must gas have its own version of everything (the gas version
655 had the correct value)
657 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
660 properly support i960 architecture and output correct reloc stuff.
662 * bfd.h: added prototype for bfd_printable_arch_mach, added
665 * coff-code.h: Applied patches from chrisb to support i960
666 architecture, zero relocs and swap them correcly and conditionally
667 compiled the timestamp.
669 * sunos.c: Made the default section alignment 2^3 so that doubles
670 are done properly. Fixed the same reloc bug that was in b.out.c
672 * sysdep.h: Now compiles on a Posix box
674 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
676 * icoff.c: Fix comment on big-endian version.
677 * coff-code.h: Make HAS_RELOC really work (it's backwards from
678 F_RELFLG). Set F_AR32WR in output files if little endian
683 * archures.c fixed =/== typo
685 * sunos.c added architecture stuff for output. Fixed
686 bug where files where vma(data) != size(text)
687 were processed wrong.
689 * coff-code.h added a lint cast
691 * (../include/a.out.sun4.h) fixed it so zmagic
696 * archive.c removed loads of includes, and fixed bug where string
697 table didn't have a null at the end.
699 * bfd.c fixed includes, added symbols argument to
700 canonicalize_reloc entry point.
702 * libbfd.c fixed includes and added some lint patches.
704 * targets.c added both sorts of intel coff.
706 * b.out.c fixed included, changed was the canonical
709 * icoff.c added support for callj and big and little
712 * opncls.c added chmod+xing for files with EXEC_P set.
714 * sunos.c fixed includes. Changed default section
715 alignement to words. Fixed relocation stuff to work with
718 * bfd.h various new types added, prototype for new
719 reloc calls, changed bfd->iostream to a void *
720 to including files don't need stdio.h.
722 * libcoff.h added conversion table to tie relocs to
727 * coff-code.h fixed includes. Added code to support
728 big and little endian formats. Various lints. Better
729 processing of symbols. Changed reloc stuff to new
732 * libbfd.h fixed includes
737 * bfd.h changed name of alignment entry in sec_struct to
738 alignment_power, because of conflicting uses within bfd.
739 Now it should be obvious that it's a 2**n alignment
740 specifier. Removed start_pad, end_alignment, block, minsize,
741 output_file_alignment, subsection_alignment and original_vma fields.
742 Added align_power() macro. Fixed bfd_section_alignment
743 acessor macros. Added bfd_symbol_same_target macro.
745 * b.out.c (b_out_write_object_contents) fixed to use
746 new alignment member. Fixed (callj_callback) to use section
747 relative symbols properly.
749 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
750 Fixed (translate_from_native_sym_flags) to correctly make
751 symbols section relative.
753 * bfd.c (bfd_errmsg) fixed various enum cast problems.
754 (bfd_make_section) took out initialization of obsolete members.
755 (bfd_print_symbol_vandf) added
757 * opncls.c (bfd_create) created.
759 * coff-code.h (coff_new_section_hook) took away refs
760 to obsolete members. (make_a_section_from_file) added
761 conversion between alignment types. (coff_symbol_from)
762 added. (coff_count_linenumbers) only counts linenumbers
763 if symbol is of coff-type. (coff_mangle_symbols) only
764 heavily mangles symbols if symbol is coff-type.
765 (coff_write_symbols) various lints. (coff_write_object_contents)
766 various lints and modification for alignment conversion.
767 (coff_slurp_relocs) fixed for use with new asection shape.
771 * archive.c lots of lint
773 * b.out.c added callj relocation support, upgrated reloc howto.
774 Fixed so that asymbol and reloc records are output
777 * bfd.c lots of lint, support for new bfd entry point
780 * bfd.h changed definition of asymbol to contain pointer to
781 owning bfd, removed target dependencies.
783 * cache.c took out print statements, put in BFD_ASSERT calls.
785 * coff-code.h various lints, corrected linenumber output
786 functionality. Added support for new style asymbols and
787 bfd_print_symbol. Fixed so that asymbol and
788 reloc records are handled correctly. Added timestamp.
790 * icoff.c Added support for new howto shape.

798 * libcoff.h added support for new asymbol shape.
800 * sunos.c various lints. Added support for new asymbol shape
801 and bfd_print_symbol.
805 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
806 pointer lint. Added support for callj relocation. Fixed bug where
807 the last 32 bytes of the text section were overwritten by data. Fixed bug
808 where archives of b.out didn't work due bfd_slurp_extended_name_table
811 * sunos.c added support for n_other field. Braced the howto table so
812 that it won't be affected by any lengthing of the howto struct typedef.
815 * bfd.h added support for n_other field, added special_function
816 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
819 * bfd.c upgraded bfd_perform_relocation, various lints.
821 Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl)
823 * ChangeLog: Started ChangeLog for BFD.
824 * ToDo: Create file for suggestions.
826 * Makefile: Support easy loading into Saber C.
827 Add dependencies for icoff.o and bcs88kcoff.o.
828 Rename coff.c to coff-code.h. Change callers.
830 * bfd.c (bfd_check_format): Allow the check_format routines
831 to return the desired target vector, rather than just a Boolean.
832 bfd.h (bfd_check_format): Change function pointer return type.
833 archive.c (bfd_generic_archive_p): change callee.
834 b.out.c (b_out_little_object_p, b_out_big_object_p,
835 b_out_real_object_p): change callee.
836 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
837 in check_format transfer vectors that need a filler.
838 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
839 bcs88kcoff.c: change callee.
840 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
841 icoff.c: change callee.
842 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
844 * libbfd.c (zalloc): It should actually zero the storage!
845 This was commented out for some reason.
847 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
848 This is so callers can avoid <stdlib.h> which doesn't exist
851 * bfd.c (map_over_sections): Add debugging code, since I
852 noticed the section count for sunos core files was bad, but only
853 GDB had detected the problem.
854 (bfd_set_section_lineno_size, bfd_set_section_linenos,
855 bfd_get_section_linenos): Remove obsolete functions.
856 (bfd_apply_relocations): Use longs, not ints, for the math.
858 * bfd.h: Declare enum boolean and struct bfd_target as well
859 as typedefs for them. Remove obsolete
860 bfd_get_section_lineno_size.
862 * cache.c: Make the "fdopen" support work. Keep better track
863 of how many files are open. Centralize the opening of files
864 and be sure bfd_open[rw] actually try to open the file. Evade
865 linked list initialization problems.
867 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
869 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
871 * cplus-dem.c: Delete file, since it is not part of BFD.
873 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.

876 * sunos.c (sunos4_core_file_p): Set section count.
877 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
878 obsolete definitions.
879 (_write_symbol_table): Initialize <idx> counter.
880 (foop): Eliminate debugging code.
