   1 Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
   2
   3         * Makefile.in, m68kcoff.c, targets.c
   4         Test new structure code with a 68k coff implementaion
   5
   6         * coff-code.h, icoff.c, coffswap.c, libcoff.h
   7         Fixed all the places where there were problems with the size and
   8         alignments of structures on disk and structures in memory. #ifed out
   9         all the code in coffswap.c, since it should be done using the target
  10         swap routines now.
  11
  12
  13 Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  14
  15         * ieee.c (do_one, ieee_slurp_section_data): now supports the load
  16         multiple reloc command.
  17
  18         * sunos.c (sunos4_set_section_contents): Made it so that sections
  19         are always padded to their alignment size.
  20
  21 Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
  22
  23         * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
  24         Clean up types and such (saber C problems).
  25         * ecoff.c:  Clean up types and such.  Remove routines that are
  26         not used.  Fix up reading and swapping of shorts from files.
  27
  28 Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
  29
  30         * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
  31         bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
  32         symbol tables if necessary when reading them in, so gdb can use
  33         them.  Add "bfd_coff_" to the names so they won't conflict with
  34         names in calling programs.  FIXME-soon:  if coff-code.h is
  35         included in two BFD modules, this will cause duplicate
  36         definitions; the routines should be exported to a separate,
  37         common, module (probably along with a mess of other ones).
  38
  39 Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
  40
  41         Improve modtime support.
  42
  43         * bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
  44         Remove #define for bfd_get_mtime.  Remove gratuitous comment.
  45         * bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
  46         BUG:  archive members still do not get correct mod times.
  47
  48         Improve floating point support for core files.
  49
  50         * sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
  51         (sunos4_core_file_p):  Create a second registers section in the
  52         core file, called ".reg2", for the float registers.
  53
  54 Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
  55
  56         * many changes to improve archive handling; found a logic flaw in
  57           bfd_check_format which only just happened to work by cooncidence.
  58
  59 Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  60
  61         * bfd.c (bfd_perform_relocation): fixed to use output_offsets
  62         correctly.
  63
  64         * bfd.h: changed type of udata in asymbol to void *, like it
  65         should be. Added bfd_reloc_dangerous enum member.
  66
  67         * coff-code.h: Fixed it so that internally generated symbols get
  68         their values relocated correctly in all cases. Removed calls to
  69         xmalloc.
  70
  71         * icoff.c: Not understanding the destination symbol of a reloc is
  72         not a failure any more, just 'dangerous'. This allows linking of
  73         b.out and coff images.
  74
  75         * sunos.c: Cleaned up the way that ZMAGIC section sizes are
  76         calculated.
  77
  78
  79 Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
  80
  81         * sunos.c (translate_to_native_sym_flags): fixed
  82         sym_pointer->n_value so that symbols on the way out get their
  83         section relative values calculated correctly.
  84
  85         * coff-code.h (mangle_symbols): fixed problem where tags were not
  86         being relocated for structs, enums, unions. Also various lints.
  87
  88 Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
  89
  90         * archive.c (get_elt_at_filepos): system_call_error returned
  91           incorrectly.
  92
  93 Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)
  94
  95         * Resolve the use of no_error and system_call_error.
  96           The bfd library itself now will never set bfd_error to
  97           no_error.
  98
  99           The code still needs to be combed to make sure all the error
 100           codes are correct.  I suspect they are not always set correctly.
 101
 102         * The names of all the messages have _ prepended because the sun
 103           bundled compiler can't distinguish from a macro which takes an
 104           argument and the same identifier in a non-macro context.
 105
 106         * The reason for the above being that entry points which used to
 107           be trampoline functions are now just macros which expand to a
 108           direct call through the bfd's xfer vector.
 109
 110         * (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
 111           must gas have its own version of everything (the gas version
 112           had the correct value)
 113
 114 Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
 115
 116         * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
 117         properly support i960 architecture and output correct reloc stuff.
 118
 119         * bfd.h: added prototype for bfd_printable_arch_mach, added
 120         BFD_FAIL
 121
 122         * coff-code.h: Applied patches from chrisb to support i960
 123         architecture, zero relocs and swap them correcly and conditionally
 124         compiled the timestamp.
 125
 126         * sunos.c: Made the default section alignment 2^3 so that doubles
 127         are done properly. Fixed the same reloc bug that was in b.out.c
 128
 129         * sysdep.h: Now compiles on a Posix box
 130
 131 Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
 132
 133         * icoff.c:  Fix comment on big-endian version.
 134         * coff-code.h:  Make HAS_RELOC really work (it's backwards from
 135         F_RELFLG).  Set F_AR32WR in output files if little endian
 136         architecture.
 137
 138 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
 139
 140         * archures.c fixed =/== typo
 141
 142         * sunos.c added architecture stuff for output. Fixed
 143         bug where files where vma(data) != size(text)
 144         were processed wrong.
 145
 146         * coff-code.h added a lint cast
 147
 148         * (../include/a.out.sun4.h) fixed it so zmagic
 149         worked
 150
 151 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
 152
 153         * archive.c removed loads of includes, and fixed bug where string
 154         table didn't have a null at the end.
 155
 156         * bfd.c fixed includes, added symbols argument to
 157         canonicalize_reloc entry point.
 158
 159         * libbfd.c fixed includes and added some lint patches.
 160
 161         * targets.c added both sorts of intel coff.
 162
 163         * b.out.c fixed included, changed was the canonical
 164         relocs were done.
 165
 166         * icoff.c added support for callj and big and little
 167         enidian tables.
 168
 169         * opncls.c added chmod+xing for files with EXEC_P set.
 170
 171         * sunos.c fixed includes. Changed default section
 172         alignement to words. Fixed relocation stuff to work with
 173         new scheme
 174
 175         * bfd.h various new types added, prototype for new
 176         reloc calls, changed bfd->iostream to a void *
 177         to including files don't need stdio.h.
 178
 179         * libcoff.h added conversion table to tie relocs to
 180         canonical symbols
 181
 182         * sysdep.h created
 183
 184         * coff-code.h fixed includes. Added code to support
 185         big and little endian formats. Various lints. Better
 186         processing of symbols. Changed reloc stuff to new
 187         order
 188
 189         * libbfd.h fixed includes
 190
 191
 192 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
 193
 194         * bfd.h changed name of alignment entry in sec_struct to
 195         alignment_power, because of conflicting uses within bfd.
 196         Now it should be obvious that it's a 2**n alignment
 197         specifier. Removed start_pad, end_alignment, block, minsize,
 198         output_file_alignment, subsection_alignment and original_vma fields.
 199         Added align_power() macro. Fixed bfd_section_alignment
 200         acessor macros. Added bfd_symbol_same_target macro.
 201
 202         * b.out.c (b_out_write_object_contents) fixed to use
 203         new alignment member. Fixed (callj_callback) to use section
 204         relative symbols properly.
 205
 206         * sunos.c (sunos4_object_p) fixed to use new alignment_power.
 207         Fixed (translate_from_native_sym_flags) to correctly make
 208         symbols section relative.
 209
 210         * bfd.c (bfd_errmsg) fixed various enum cast problems.
 211         (bfd_make_section) took out initialization of obsolete members.
 212         (bfd_print_symbol_vandf) added
 213
 214         * opncls.c (bfd_create) created.
 215
 216         * coff-code.h (coff_new_section_hook) took away refs
 217         to obsolete members. (make_a_section_from_file) added
 218         conversion between alignment types. (coff_symbol_from)
 219         added. (coff_count_linenumbers) only counts linenumbers
 220         if symbol is of coff-type. (coff_mangle_symbols) only
 221         heavily mangles symbols if symbol is coff-type.
 222         (coff_write_symbols) various lints. (coff_write_object_contents)
 223         various lints and modification for alignment conversion.
 224         (coff_slurp_relocs) fixed for use with new asection shape.
 225
 226 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
 227
 228         * archive.c lots of lint
 229
 230         * b.out.c added callj relocation support, upgrated reloc howto.
 231         Fixed so that asymbol and reloc records are output
 232         correctly.
 233
 234         * bfd.c lots of lint, support for new bfd entry point
 235         bfd_print_symbol.
 236
 237         * bfd.h changed definition of asymbol to contain pointer to
 238         owning bfd, removed target dependencies.
 239
 240         * cache.c took out print statements, put in BFD_ASSERT calls.
 241
 242         * coff-code.h various lints, corrected linenumber output
 243         functionality. Added support for new style asymbols and
 244         bfd_print_symbol. Fixed so that asymbol and
 245         reloc records are handled correctly. Added timestamp.
 246
 247         * icoff.c Added support for new howto shape.
 248
 249         * liba.out.h Added support for new asymbol shape
 250
 251         * libbfd.c various lints

 256
 257         * sunos.c  various lints. Added support for new asymbol shape
 258         and bfd_print_symbol.
 259
 260 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
 261
 262         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
 263         pointer lint. Added support for callj relocation. Fixed bug where
 264         the last 32 bytes of the text section were overwritten by data. Fixed bug
 265         where archives of b.out didn't work due bfd_slurp_extended_name_table
 266         returning false.
 267
 268         * sunos.c added support for n_other field. Braced the howto table so
 269         that it won't be affected by any lengthing of the howto struct typedef.
 270         Various lints
 271
 272         * bfd.h added support for n_other field, added special_function
 273         reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x

 277
 278 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
 279
 280         * ChangeLog:  Started ChangeLog for BFD.
 281         * ToDo:  Create file for suggestions.
 282
 283         * Makefile:  Support easy loading into Saber C.
 284         Add dependencies for icoff.o and bcs88kcoff.o.
 285         Rename coff.c to coff-code.h.  Change callers.
 286
 287         * bfd.c (bfd_check_format):  Allow the check_format routines
 288         to return the desired target vector, rather than just a Boolean.
 289         bfd.h (bfd_check_format):  Change function pointer return type.
 290         archive.c (bfd_generic_archive_p):  change callee.
 291         b.out.c (b_out_little_object_p, b_out_big_object_p,
 292         b_out_real_object_p):  change callee.
 293         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
 294         in check_format transfer vectors that need a filler.
 295         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
 296         bcs88kcoff.c:  change callee.
 297         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
 298         icoff.c:  change callee.
 299         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
 300
 301         * libbfd.c (zalloc):  It should actually zero the storage!
 302         This was commented out for some reason.
 303
 304         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
 305         This is so callers can avoid <stdlib.h> which doesn't exist
 306         on older systems.
 307
 308         * bfd.c (map_over_sections):  Add debugging code, since I
 309         noticed the section count for sunos core files was bad, but only
 310         GDB had detected the problem.
 311         (bfd_set_section_lineno_size, bfd_set_section_linenos,
 312         bfd_get_section_linenos):  Remove obsolete functions.
 313         (bfd_apply_relocations):  Use longs, not ints, for the math.
 314
 315         * bfd.h:  Declare enum boolean and struct bfd_target as well
 316         as typedefs for them.  Remove obsolete
 317         bfd_get_section_lineno_size.
 318
 319         * cache.c:  Make the "fdopen" support work.  Keep better track
 320         of how many files are open.  Centralize the opening of files
 321         and be sure bfd_open[rw] actually try to open the file.  Evade
 322         linked list initialization problems.
 323
 324         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
 325
 326         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
 327
 328         * cplus-dem.c:  Delete file, since it is not part of BFD.
 329
 330         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
 331         (bfd_openr, bfd_openw):  Actually open the file, give error now.
 332
 333         * sunos.c (sunos4_core_file_p):  Set section count.
 334         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
 335         obsolete definitions.
 336         (_write_symbol_table):  Initialize <idx> counter.
 337         (foop):  Eliminate debugging code.
 338
 339
 340
 341
