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

 246         and bfd_print_symbol.
 247
 248 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
 249
 250         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
 251         pointer lint. Added support for callj relocation. Fixed bug where
 252         the last 32 bytes of the text section were overwritten by data. Fixed bug
 253         where archives of b.out didn't work due bfd_slurp_extended_name_table
 254         returning false.
 255
 256         * sunos.c added support for n_other field. Braced the howto table so
 257         that it won't be affected by any lengthing of the howto struct typedef.
 258         Various lints
 259
 260         * bfd.h added support for n_other field, added special_function
 261         reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x

 265
 266 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
 267
 268         * ChangeLog:  Started ChangeLog for BFD.
 269         * ToDo:  Create file for suggestions.
 270
 271         * Makefile:  Support easy loading into Saber C.
 272         Add dependencies for icoff.o and bcs88kcoff.o.
 273         Rename coff.c to coff-code.h.  Change callers.
 274
 275         * bfd.c (bfd_check_format):  Allow the check_format routines
 276         to return the desired target vector, rather than just a Boolean.
 277         bfd.h (bfd_check_format):  Change function pointer return type.
 278         archive.c (bfd_generic_archive_p):  change callee.
 279         b.out.c (b_out_little_object_p, b_out_big_object_p,
 280         b_out_real_object_p):  change callee.
 281         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
 282         in check_format transfer vectors that need a filler.
 283         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
 284         bcs88kcoff.c:  change callee.
 285         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
 286         icoff.c:  change callee.
 287         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
 288
 289         * libbfd.c (zalloc):  It should actually zero the storage!
 290         This was commented out for some reason.
 291
 292         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
 293         This is so callers can avoid <stdlib.h> which doesn't exist
 294         on older systems.
 295
 296         * bfd.c (map_over_sections):  Add debugging code, since I
 297         noticed the section count for sunos core files was bad, but only
 298         GDB had detected the problem.
 299         (bfd_set_section_lineno_size, bfd_set_section_linenos,
 300         bfd_get_section_linenos):  Remove obsolete functions.
 301         (bfd_apply_relocations):  Use longs, not ints, for the math.
 302
 303         * bfd.h:  Declare enum boolean and struct bfd_target as well
 304         as typedefs for them.  Remove obsolete
 305         bfd_get_section_lineno_size.
 306
 307         * cache.c:  Make the "fdopen" support work.  Keep better track
 308         of how many files are open.  Centralize the opening of files
 309         and be sure bfd_open[rw] actually try to open the file.  Evade
 310         linked list initialization problems.
 311
 312         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
 313
 314         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
 315
 316         * cplus-dem.c:  Delete file, since it is not part of BFD.
 317
 318         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
 319         (bfd_openr, bfd_openw):  Actually open the file, give error now.
 320
 321         * sunos.c (sunos4_core_file_p):  Set section count.
 322         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
 323         obsolete definitions.
 324         (_write_symbol_table):  Initialize <idx> counter.
 325         (foop):  Eliminate debugging code.
 326
 327
 328
 329
