   1 Tue May 28 17:21:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
   2
   3         * Merge in changes from gdb-3.95 release.
   4         Makefile.in:  Allow hmake and tmake files to add OFILES.
   5         aoutf1.h:
   6         bfd.c:  support specific targets as well as searching.  When
   7         searching, take default target in preference to others.
   8         bfd.doc:  typos
   9         ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
  10         liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
  11         libbfd.h:  Support specific targets as well as searching.
  12         opncls.c:  Support specific targets as well as searching.
  13         targets.c:  Search is short-circuited if default target matches.
  14         liboasys.c, libieee.c:  Undo bothner changes that make macros
  15         work to the left of assignment, but which depend on the
  16         representations of different pointer types being the same.
  17
  18 Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  19
  20         * i386coff.c: created.
  21         * coffcode.h: added support for 386.
  22         * Makefile.in: added support for 386.
  23         * ../include/i386coff.h: created
  24
  25 Wed May 22 07:26:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  26
  27         * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
  28         DEFUNS
  29
  30
  31 Tue May 21 08:58:58 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  32         (bothner)
  33         * opncls.c: Changed obstack_chunk_alloc use xmalloc
  34
  35 Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  36
  37         * everything: Removed sysdep.h from bfd.h and put back into files
  38         from which it was split out. Now 64 bit version is built with a
  39         -DHOST_64_BIT="long long" on the compile line.
  40
  41
  42 Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  43
  44         Changed all the [get|put][name] routines to use  [get|put]_[size
  45         in bytes].
  46
  47         Put in support for 64 bit work. Now two versions of bfd may be
  48         generated, according to the state of TARGET_64_BIT, one which is
  49         32 bit only, and one which is 64/32 bits.
  50         Created new back end 'demo64' to test 64 bit functionality.
  51
  52         Renamed some files to work on DOS.
  53
  54         * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
  55         64bit transfer  * icoff.c: added 64bit transfer * ieee.c: name
  56         chage, 64 bit transfer. * liba.out.h: Split out common code from
  57         sunos and newsos into liba.out. Name changes and prototype mods. *
  58         libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
  59         prototypes for new functions. * libcoff.h: lint * libieee.h: make
  60         work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
  61         change and 64bit stuff.* newsos3.c: common code removed, new jump
  62         table. * oasys.c: Name change * opncls.c: Portability fixes *
  63         srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
  64         Added demo * aout32, aout64.c include  aoutx.h * bout.c: used to
  65         be called b.out.c * coffcode.h: used to be called coff-code.h, now
  66         64bit ized. * demo64.c: 64 bit a.out back end

  72 Thu May 16 16:02:07 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  73         from bothner
  74         * libieee.h: Make ieee_data and ieee_ar_data macros usable
  75         on LHS of assignment, even when using old compilers.
  76         * liboasys.h: Ditto for oasys_data and oasys_ar_data.
  77         * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
  78         * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
  79         * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
  80         * targets.c: Add declaration of newsos3_vec.
  81
  82
  83 Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  84
  85         * aout.c: fixxed some of the problems with filepos calculation.
  86         (swap_ext_reloc): fixed problem with creation of relocs.
  87         (aout_set_section_contents): fixed filepos problem
  88
  89         * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
  90         (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
  91         (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
  92         (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
  93         cleaned up. (coff_write_object_contents) cleaned up.
  94
  95         * ecoff.c: Totally different. Now supports ecoff fully.
  96
  97         * icoff.c: fixed problems in relocation callout.
  98
  99         * libcoff.h: (struct icofdata) removed hdr structure from tdata.
 100
 101         * m68kcoff.c: updated target vector.
 102
 103         * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
 104         choose_reloc_size. (sunos4_write_object_contents) now calls
 105         choose_reloc_size so outputs relocs correctly, also calculates the
 106         size of the sections correctly.
 107
 108
 109
 110 Fri May 10 16:58:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
 111
 112         Merge Per Bothner's changes to modularize BFD a.out a bit.
 113
 114         * libbfd.h, libbfd.c (bfd_generic_get_section_contents):  Add.
 115         * ieee.c:  Cast enums to int before comparing them, for brain-
 116         dead compilers.
 117         * coff-code.h:  Remove coff_get_section_contents, and use the
 118         generic one instead.
 119
 120         * aout.c:  Derive new module from sunos.c, containing generic
 121         support code for all kinds of a.out files.
 122
 123         * sunos.c: Remove all code that goes in aout.c.  Split out
 124         machine dependent followup in sunos4_object_p into
 125         sunos4_callback.  Use JUMP_TABLE(aout) for the transver vector,
 126         and redefine only the names we CHANGE, not all the names.  Drop
 127         the little-endian vector, and rename the vector as sunos4 rather
 128         than generic.
 129
 130         * b.out.c:  Use aout.c routines for most of the work.  Slight
 131         changes for the new regime.  Remove close_and_cleanup and
 132         get_section_contents in favor of generics.  New transfer vector
 133         regime.
 134
 135         * newsos.c:  New support for Sony NEWS, another a.out format.
 136
 137         * ecoff.c:  Remove close_and_cleanup.  New tvec regime.
 138         * icoff.c, m88k-bcs.c:  Add write_contents to tvec.
 139         * ieee.c, oasys.c:  Remove close_and_cleanup, add write_contents
 140         to tvec.
 141         * opncls.c (bfd_close):  Call format-dependent write_contents
 142         routine, if writing, before calling target-dependent
 143         close_and_cleanup routine (which is now always generic, I think).
 144         * srec.c:  Use bfd_alloc instead of malloc.  Remove
 145         close_and_cleanup and move code from it to
 146         srec_write_object_contents.  Add write_contents to tvec.
 147         * targets.c:  Remove a.out little vector, replace a.out big
 148         vector with SunOS vector.  FIXME:  Need Vax support again now.
 149
 150         * libbfd.h:  Add write_contents format-dependent-vector to the
 151         bfd_target vector.  Supply a generic close_and_cleanup routine.
 152         * liba.out.h:  Handle the new aout.c split.  Add prototypes for
 153         all routines defined in aout.c.  Rename "sunos" things to "aout"
 154         things.  Add a few fields where needed for various formats.
 155         * Makefile.in:  Add aout.c and newsos.c.
 156
 157         * archive.c, ieee.c, oasys.c:  Lint.
 158
 159 Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 160
 161         * ../include/bfd.h
 162         changed forward declaration struct stat; to reduce warnings. Changed
 163         comment on bfd_h_<x>_x.
 164
 165         * ../include/m68kcoff.h, ../include/intel-coff.h,
 166         ../include/m88k-bcs.h
 167         Now there are two incarnations of relocs, linenos and syments. One for
 168         internal digestion, and one full of char arrays for I/O. The original
 169         names have gone to detect errors.
 170
 171         * Makefile.in, m68kcoff.c, targets.c
 172         Test new structure code with a 68k coff implementaion
 173
 174         * coff-code.h, icoff.c, coffswap.c, libcoff.h
 175         Fixed all the places where there were problems with the size and
 176         alignments of structures on disk and structures in memory. #ifed out
 177         all the code in coffswap.c, since it should be done using the target
 178         swap routines now.
 179
 180 Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 181
 182         * ieee.c (do_one, ieee_slurp_section_data): now supports the load
 183         multiple reloc command.
 184
 185         * sunos.c (sunos4_set_section_contents): Made it so that sections
 186         are always padded to their alignment size.
 187
 188 Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
 189
 190         * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
 191         Clean up types and such (saber C problems).
 192         * ecoff.c:  Clean up types and such.  Remove routines that are
 193         not used.  Fix up reading and swapping of shorts from files.
 194
 195    Notes on bfd-0.5.2-patch1a, from Per Bothner:
 196
 197         * a.out.vax.c: Remove two bogus "static" from prototypes.
 198
 199         * ecoff.c: Got rid of lots of non-working junk (that had
 200         been copied directly from coff-code.h).
 201         Updated to be consistent with updates to icoff.c and coff-code.h.
 202
 203         * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
 204         if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
 205
 206         * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
 207         but until the target_vector is automatically generated,
 208         it's as good as any. Note that the text offset is the only
 209         difference between NewsOS and SunOs (including magic numbers).
 210         (Most of the sunos_* routines should to renamed bsd_*
 211         and move to a bsd.c file. Then (and when the target_vector
 212         is automatically generated) it might make sense to create
 213         a separate Sony target.)
 214
 215         * sysdep.h: Don't declare fread and fwrite. Causes trouble
 216         on some systems, and doesn't help on others.
 217         Similarly, only define X_OK if not already defined.
 218
 219         * trad-core.c: Don't include sys/stat.h - at least
 220         on NewsOS 3, it has already been included.
 221
 222 Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
 223
 224         * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
 225         bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
 226         symbol tables if necessary when reading them in, so gdb can use
 227         them.  Add "bfd_coff_" to the names so they won't conflict with
 228         names in calling programs.  FIXME-soon:  if coff-code.h is
 229         included in two BFD modules, this will cause duplicate
 230         definitions; the routines should be exported to a separate,
 231         common, module (probably along with a mess of other ones).
 232
 233 Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 234
 235         Improve modtime support.
 236
 237         * bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
 238         Remove #define for bfd_get_mtime.  Remove gratuitous comment.
 239         * bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
 240         BUG:  archive members still do not get correct mod times.
 241
 242         Improve floating point support for core files.
 243
 244         * sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
 245         (sunos4_core_file_p):  Create a second registers section in the
 246         core file, called ".reg2", for the float registers.
 247
 248 Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 249
 250         * many changes to improve archive handling; found a logic flaw in
 251           bfd_check_format which only just happened to work by cooncidence.
 252
 253 Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 254
 255         * bfd.c (bfd_perform_relocation): fixed to use output_offsets
 256         correctly.
 257
 258         * bfd.h: changed type of udata in asymbol to void *, like it
 259         should be. Added bfd_reloc_dangerous enum member.
 260
 261         * coff-code.h: Fixed it so that internally generated symbols get
 262         their values relocated correctly in all cases. Removed calls to
 263         xmalloc.
 264
 265         * icoff.c: Not understanding the destination symbol of a reloc is
 266         not a failure any more, just 'dangerous'. This allows linking of
 267         b.out and coff images.
 268
 269         * sunos.c: Cleaned up the way that ZMAGIC section sizes are
 270         calculated.
 271
 272
 273 Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 274
 275         * sunos.c (translate_to_native_sym_flags): fixed
 276         sym_pointer->n_value so that symbols on the way out get their
 277         section relative values calculated correctly.
 278
 279         * coff-code.h (mangle_symbols): fixed problem where tags were not
 280         being relocated for structs, enums, unions. Also various lints.
 281
 282 Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 283
 284         * archive.c (get_elt_at_filepos): system_call_error returned
 285           incorrectly.
 286
 287 Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
 288
 289         * Resolve the use of no_error and system_call_error.
 290           The bfd library itself now will never set bfd_error to
 291           no_error.
 292
 293           The code still needs to be combed to make sure all the error
 294           codes are correct.  I suspect they are not always set correctly.
 295
 296         * The names of all the messages have _ prepended because the sun
 297           bundled compiler can't distinguish from a macro which takes an
 298           argument and the same identifier in a non-macro context.
 299
 300         * The reason for the above being that entry points which used to
 301           be trampoline functions are now just macros which expand to a
 302           direct call through the bfd's xfer vector.
 303
 304         * (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
 305           must gas have its own version of everything (the gas version
 306           had the correct value)
 307
 308 Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 309
 310         * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
 311         properly support i960 architecture and output correct reloc stuff.
 312
 313         * bfd.h: added prototype for bfd_printable_arch_mach, added
 314         BFD_FAIL
 315
 316         * coff-code.h: Applied patches from chrisb to support i960
 317         architecture, zero relocs and swap them correcly and conditionally
 318         compiled the timestamp.
 319
 320         * sunos.c: Made the default section alignment 2^3 so that doubles
 321         are done properly. Fixed the same reloc bug that was in b.out.c
 322
 323         * sysdep.h: Now compiles on a Posix box
 324
 325 Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 326
 327         * icoff.c:  Fix comment on big-endian version.
 328         * coff-code.h:  Make HAS_RELOC really work (it's backwards from
 329         F_RELFLG).  Set F_AR32WR in output files if little endian
 330         architecture.
 331
 332 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
 333
 334         * archures.c fixed =/== typo
 335
 336         * sunos.c added architecture stuff for output. Fixed
 337         bug where files where vma(data) != size(text)
 338         were processed wrong.
 339
 340         * coff-code.h added a lint cast
 341
 342         * (../include/a.out.sun4.h) fixed it so zmagic
 343         worked
 344
 345 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
 346
 347         * archive.c removed loads of includes, and fixed bug where string
 348         table didn't have a null at the end.
 349
 350         * bfd.c fixed includes, added symbols argument to

 387
 388         * bfd.h changed name of alignment entry in sec_struct to
 389         alignment_power, because of conflicting uses within bfd.
 390         Now it should be obvious that it's a 2**n alignment
 391         specifier. Removed start_pad, end_alignment, block, minsize,

 399
 400         * sunos.c (sunos4_object_p) fixed to use new alignment_power.
 401         Fixed (translate_from_native_sym_flags) to correctly make
 402         symbols section relative.
 403

 411         to obsolete members. (make_a_section_from_file) added
 412         conversion between alignment types. (coff_symbol_from)
 413         added. (coff_count_linenumbers) only counts linenumbers
 414         if symbol is of coff-type. (coff_mangle_symbols) only
 415         heavily mangles symbols if symbol is coff-type.

 426         correctly.
 427
 428         * bfd.c lots of lint, support for new bfd entry point
 429         bfd_print_symbol.
 430
 431         * bfd.h changed definition of asymbol to contain pointer to
 432         owning bfd, removed target dependencies.
 433
 434         * cache.c took out print statements, put in BFD_ASSERT calls.
 435
 436         * coff-code.h various lints, corrected linenumber output
 437         functionality. Added support for new style asymbols and

 454 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
 455
 456         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
 457         pointer lint. Added support for callj relocation. Fixed bug where
 458         the last 32 bytes of the text section were overwritten by data. Fixed bug
 459         where archives of b.out didn't work due bfd_slurp_extended_name_table
 460         returning false.
 461
 462         * sunos.c added support for n_other field. Braced the howto table so
 463         that it won't be affected by any lengthing of the howto struct typedef.

 472 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
 473
 474         * ChangeLog:  Started ChangeLog for BFD.
 475         * ToDo:  Create file for suggestions.
 476
 477         * Makefile:  Support easy loading into Saber C.
 478         Add dependencies for icoff.o and bcs88kcoff.o.
 479         Rename coff.c to coff-code.h.  Change callers.
 480
 481         * bfd.c (bfd_check_format):  Allow the check_format routines
 482         to return the desired target vector, rather than just a Boolean.
 483         bfd.h (bfd_check_format):  Change function pointer return type.
 484         archive.c (bfd_generic_archive_p):  change callee.
 485         b.out.c (b_out_little_object_p, b_out_big_object_p,
 486         b_out_real_object_p):  change callee.
 487         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
 488         in check_format transfer vectors that need a filler.
 489         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
 490         bcs88kcoff.c:  change callee.
 491         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
 492         icoff.c:  change callee.
 493         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
 494
 495         * libbfd.c (zalloc):  It should actually zero the storage!
 496         This was commented out for some reason.
 497
 498         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
 499         This is so callers can avoid <stdlib.h> which doesn't exist
 500         on older systems.
 501
 502         * bfd.c (map_over_sections):  Add debugging code, since I
 503         noticed the section count for sunos core files was bad, but only
 504         GDB had detected the problem.
 505         (bfd_set_section_lineno_size, bfd_set_section_linenos,
 506         bfd_get_section_linenos):  Remove obsolete functions.
 507         (bfd_apply_relocations):  Use longs, not ints, for the math.
 508
 509         * bfd.h:  Declare enum boolean and struct bfd_target as well
 510         as typedefs for them.  Remove obsolete
 511         bfd_get_section_lineno_size.
 512
 513         * cache.c:  Make the "fdopen" support work.  Keep better track
 514         of how many files are open.  Centralize the opening of files
 515         and be sure bfd_open[rw] actually try to open the file.  Evade
 516         linked list initialization problems.
 517
 518         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
 519
 520         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
 521
 522         * cplus-dem.c:  Delete file, since it is not part of BFD.
 523
 524         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
 525         (bfd_openr, bfd_openw):  Actually open the file, give error now.
 526
 527         * sunos.c (sunos4_core_file_p):  Set section count.
 528         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
 529         obsolete definitions.
 530         (_write_symbol_table):  Initialize <idx> counter.
 531         (foop):  Eliminate debugging code.
