bfd/ChangeLog

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

 232
 233 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
 234
 235         * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
 236         pointer lint. Added support for callj relocation. Fixed bug where
 237         the last 32 bytes of the text section were overwritten by data. Fixed bug
 238         where archives of b.out didn't work due bfd_slurp_extended_name_table
 239         returning false.
 240
 241         * sunos.c added support for n_other field. Braced the howto table so
 242         that it won't be affected by any lengthing of the howto struct typedef.
 243         Various lints
 244
 245         * bfd.h added support for n_other field, added special_function

 250
 251 Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)
 252
 253         * ChangeLog:  Started ChangeLog for BFD.
 254         * ToDo:  Create file for suggestions.
 255
 256         * Makefile:  Support easy loading into Saber C.
 257         Add dependencies for icoff.o and bcs88kcoff.o.
 258         Rename coff.c to coff-code.h.  Change callers.
 259
 260         * bfd.c (bfd_check_format):  Allow the check_format routines
 261         to return the desired target vector, rather than just a Boolean.
 262         bfd.h (bfd_check_format):  Change function pointer return type.
 263         archive.c (bfd_generic_archive_p):  change callee.
 264         b.out.c (b_out_little_object_p, b_out_big_object_p,
 265         b_out_real_object_p):  change callee.
 266         libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
 267         in check_format transfer vectors that need a filler.
 268         libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
 269         bcs88kcoff.c:  change callee.
 270         coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
 271         icoff.c:  change callee.
 272         sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.
 273
 274         * libbfd.c (zalloc):  It should actually zero the storage!
 275         This was commented out for some reason.
 276
 277         * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
 278         This is so callers can avoid <stdlib.h> which doesn't exist
 279         on older systems.
 280
 281         * bfd.c (map_over_sections):  Add debugging code, since I
 282         noticed the section count for sunos core files was bad, but only
 283         GDB had detected the problem.
 284         (bfd_set_section_lineno_size, bfd_set_section_linenos,
 285         bfd_get_section_linenos):  Remove obsolete functions.
 286         (bfd_apply_relocations):  Use longs, not ints, for the math.
 287
 288         * bfd.h:  Declare enum boolean and struct bfd_target as well
 289         as typedefs for them.  Remove obsolete
 290         bfd_get_section_lineno_size.
 291
 292         * cache.c:  Make the "fdopen" support work.  Keep better track
 293         of how many files are open.  Centralize the opening of files
 294         and be sure bfd_open[rw] actually try to open the file.  Evade
 295         linked list initialization problems.
 296
 297         * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.
 298
 299         * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.
 300
 301         * cplus-dem.c:  Delete file, since it is not part of BFD.
 302
 303         * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
 304         (bfd_openr, bfd_openw):  Actually open the file, give error now.
 305
 306         * sunos.c (sunos4_core_file_p):  Set section count.
 307         (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
 308         obsolete definitions.
 309         (_write_symbol_table):  Initialize <idx> counter.
 310         (foop):  Eliminate debugging code.
 311
 312
 313
 314
