   6
   7         * relax.c (build_it): don't allocate space in the output file for
   8         stuff if -R flag applys to it.
   9         * ldfile.c: merge in VMS filename support
  10         * ldmain.c (main): take out ./ from library path, and close file

  35         * ldexp.c, ldlang.c: now build memory shape tree in obstacks
  36         rather than with raw malloc, makes it easier to track where memory
  37         is going.
  38         * ldsym.h, ldsym.c: create obstack for all global symbols too.
  39         * ldwrite.c (ldwrite): moved malloc so only used when needed.

  62
  63         * Makefile.in: rework CFLAGS so that they can be passed on the

  83
  84         * Makefile.in (install): Install second copy in $(tooldir)/bin

  88
  89         * ldlex.l, ldgram.y, ldlex.h: Rewrote lexer. Now it's much nicer.

 142         * cplus-dem.c: yet another copy of this - maybe it should go into
 143         libiberty ?
 144         * ldgram.y: now -V and -v have different actions

 153           copyrights to '92, changed some from Cygnus to FSF.
 154
 155 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
 156
 157         * Makefile.in:  Change mkscript rule into one for ./mkscript
 158         (for the sake of makes that don't realize they're the same).

 160         * genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.
 161
 162 Mon Feb 17 12:04:36 1992  Per Bothner  (bothner at cygnus.com)
 163
 164         * Makefile.in, and new files hp300bsd.sh, config/mh-hp300bsd,

 166
 167 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 168
 169         Major rewrite of how ld is configured.  The major idea
 170         is to use shell scripts to generate everything.
 171         * generic.em replaces ldtemplate.
 172         * Other *.em files replace various *.c files.
 173         A *.em file is a shell script that generates the corresponding
 174         ld__*.c file that implements an emulation.  This is usually
 175         a straight 'cat' of a here-document, possibly with substitutions.
 176         * Script files (*.sc) are places by *.sc-sh scripts.
 177         Again, these are simple shell scripts that 'cat'
 178         here-documents, usually with some substitutions.
 179         The output a *.sc-sh is a script file.
 180         * Each emulation is defined by a short shell script with
 181         extension *.sh that specifies the emulation-specific
 182         parameters (such as the name of the *.sh-sc and *.em
 183         files to use).
 184         * genscript.sh is the master shell script used to generate
 185         an emulation.  It is passed various argument, including
 186         the name a the emulation-speciic *.sh file that it
 187         "sources" to set variables to emulation-specifc parameters.
 188         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 189         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 190         * config/mh-foo:  Rename LDEMULATION names as appropriate
 191         (usually 'gldfoo' -> plain 'foo').
 192         * ldwrite.c:  Fixed a typo in a comment.
 193         * Makefile.in:  Major changes.  Removed some the sed
 194         magic to converts scripts, since that is now handled
 195         by genscripts.sh and the *.sc-sh scipt generators.
 196         * config.h:  Remove a bunch of macros defining emulations
 197         and targets.  This becomes one less file to edit when
 198         adding emulations or targets.
 199         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 200         emulation_name and target_name fields.
 201         * ldemul.c, ldemul.h:  Define some default functions used
 202         by most emulations (and remove from the *.em scripts).
 203         * ldemul.c (ldemul_choose_target):  Search the new
 204         ld_emulations array using a loop (instead of a hardwired
 205         nested if statement).
 206         Define the ld_emulation from the automatically-geenrated
 207         ldemul-list.h.  This means you no longer have to edit ldemul.c
 208         to add a new emulation.
 209         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 210         their expansions, since the former no longer exist.
 211         * PORTING:  A very rough first draft of a porting guide.
 212
 213         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 214         to be terminated by a new-line (instead of requiring a semicolon).
 215
 216 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 217
 218         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 219         tests for NULL pointers all over the place.
 220         * ldlang.c (lang_process): remember to relocate global symbols
 221         *after* relaxing has done it stuff.
 222
 223 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 224
 225         * config/mt-coff-h8300: use EMUL like everything else
 226         * ldlang.c: (print_padding_statement): print the right address.
 227         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms
 228
 229
 230 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 231
 232         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 233         * ldlang.c (print_data_statement): print the right address.
 234
 235 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 236
 237         * Makefile.in:  The rule for testing ld by re-linking itself
 238         via an intermediate -r link was moved to the ld1 rule
 239         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 240         which allows the bootstrap rule to work.
 241         * ldctor.c (find_constructors):  Don't create a constructor
 242         list if it is already defined (as would happen if ld is
 243         invoked by collect).
 244
 245 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 246
 247         * config/mh-sparc.h: now uses libgcc.a
 248         * ldmain.c: quit using exit
 249         * *sc: use *(COMMON) rather than [COMMON]
 250         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 251         to allow preprocessing of .l file.
 252         * Makefile.in: New ldlex.l mangling
 253         * ldexp.c (fold_binary): perform expressions with % and / in
 254         integer.
 255         * ldfile.c (open_a): open archives on VMS in a special way
 256
 257
 258 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 259
 260         * ldgram.y: map -M behave in the same way as -Map (sets file name
 261         to be "-".
 262         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 263         whether or not relaxing has been done.
 264         * ldmain.c: don't open a map file if it doesn't have a name
 265         * relax.c: all the brains have moved into bfd.
 266         * ldwrite.c: ammend comment
 267
 268 Fri Jan 24 14:23:46 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 269
 270         * Makefile.in: added relax, also made three stage go through a
 271         partial link stage.
 272         * relax.c : added
 273         * config.h: if GNU960 defined, then default emulation mode is
 274         GLD960
 275         * ldexp.h, ldexp.c: map to file hooks
 276         * ldlang.c: map to file hooks
 277         * ldgram.y: added -Map -relax
 278         * ldlex.l: added -relax, -Map
 279         * ldmain.c: open map file
 280         * ldmisc.c: support for map file
 281         * ldwrite.c: new relax magic
 282
 283 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)
 284
 285         * Makefile.in, config/tm-*.h:  Clean up make output, only
 286         pass DEFAULT_EMULATION to ldmain.c.
 287
 288 Wed Dec 18 15:02:47 1991  Per Bothner  (bothner at cygnus.com)
 289
 290         * ldver.c:  Bump to version 1.94.
 291
 292 Tue Dec 10 04:07:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 293
 294         * Makefile.in: infodir belongs in datadir.
 295
 296 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
 297
 298         * Makefile.in:  Pass -y to bison.  (Again;
 299         accidentally deleted by Rich.)
 300         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 301
 302 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 303
 304         * ldindr.h: added to contain prototypes of ldindr.c
 305         * ldfile.c: include ctype.h
 306         * ldmain.c: include the requried prototype headers
 307         * ldwrite.c: get_reloc_upper_bound has been renamed

 309
 310 Fri Dec  6 23:29:26 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 311
 312         * Makefile.in: punt "fundamental" mode because it breaks my emacs
 313           macros.  install using INSTALL_PROGRAM and INSTALL_DATA.  remove
 314           spaces following hyphens, bsd make can't cope.  added
 315           standards.text support and made it look like all the other
 316           makefiles.
 317
 318         * configure.in: configure now runs entirely in objdir so make file
 319           existence checks against ${srcdir}.  Mark this directory as
 320           target dependent.
 321
 322 Thu Dec  5 22:46:16 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 323
 324         * Makefile.in: idestdir and ddestdir go away.  Added copyrights
 325           and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
 326           and mandir now keyed off datadir by default.
 327
 328 Wed Dec  4 23:36:55 1991  Per Bothner  (bothner at cygnus.com)
 329
 330         * ldver.c:  Bumped version to 1.93.
 331         * Makefile.in:  Pass -y to bison.
 332
 333 Mon Nov 25 18:28:40 1991  Steve Chamberlain  (sac at cygnus.com)
 334
 335         * config.h: h8 is now coff, not ieee
 336         * h8300hds.sc: reflect the same
 337
 338 Thu Nov 14 19:55:09 1991  Per Bothner  (bothner at cygnus.com)
 339
 340         * ldver.c (ldversion()):  Update to 1.92.
 341         * ldctor.c: There are two places constructor sets
 342         can be defined.  One of them checked for an existing
 343         duplicate, the other didn't.  Unfortunately, the latter
 344         was called after the former ...
 345         So, factor out code for inserting a new element into
 346         constructor_name_list (after checking for a duplicate)
 347         into a new function add_constructor_name, and call
 348         it from both aforementioned places (ldlang_add_constructor
 349         and ldlang_check_for_constructors).
 350
 351 Wed Nov 13 15:17:43 1991  Per Bothner  (bothner at cygnus.com)
 352
 353         * Makefile.in:  Rename .c files generated from ldtemplate
 354         to have names starting with ld__.  This helps 'make clean'.

 356 Tue Nov 12 18:36:50 1991  Steve Chamberlain  (sac at cygnus.com)
 357
 358         * Makefile.in: Take out the version number for install
 359         * m88kbcs.sc: put in contructor blocks.
 360
 361 Mon Nov 11 18:47:33 1991  Per Bothner  (bothner at cygnus.com)
 362
 363         * ldmisc.c, ldmisc.h:  Re-write info() to take a filename
 364         parameter, a format, and an arg pointer, and rename it to
 365         vfinfo().  Write info() in terms of new vfinfo().
 366         New einfo() is the same as info(), except it writes to stderr.
 367         * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
 368         ldmisc.c:  Replace "error" calls to info() by new einfo().

 370 Mon Nov 11 09:57:32 1991  Steve Chamberlain  (steve at cygnus.com)
 371
 372         * ldlex.l ldgram.y: made -V option do same as -v
 373         * Makefile.in: Added $(MINUS_G) flag so debugging can be
 374         turned off
 375
 376 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
 377          i386 aout changes from Bob Kukura
 378         * Makefile.in, config.h: added i386aout support
 379         * configure.in: fixed /h-{myhost} typo
 380         * ldgram.y: -MM now gives more boring map.
 381         * ldlang.c: now does D_PAGED flag the right way.
 382         * ldsym.c: -MM flags does the right thing.
 383
 384 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
 385
 386         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 387         * ldlang.c (init_os):  Compensate for BFD change,
 388         where bfd_make_section now returns NULL for a duplicate
 389         section request, instead of the old section.
 390
 391 Thu Oct 17 15:27:13 1991  Per Bothner  (bothner at cygnus.com)
 392
 393         * ldver.c: Bump to version 1.91 (consistent with binutils).
 394
 395 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)
 396
 397         * Makefile.in, config.h, ld.h, ldemul.c, ldexp.c, ldexp.h,
 398         ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
 399         ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
 400         ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
 401         Add or update copyright notices.
 402
 403 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 404
 405         * README: New file.
 406         * Makefile.in:  Changed installation directory name scheme
 407         to be consistent with gcc.  Also changed 'install'.
 408
 409 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 410
 411         * Makefile.in: new targets ld.mm, ld.me
 412
 413 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 414
 415         * Makefile.in, ldtemplate:  Need to use separate scripts
 416         for -n and -N options.  Yet more complication.
 417
 418 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 419
 420         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 421         work).  Add some lines to avoid Sun Make VPATH bugs.
 422
 423 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 424
 425         * news.sc: Add alignment for data segment.
 426         * ldtemplate: Add (yet another) script to get for -n or -N
 427         options.  (These need different alignment than ZMAGIC files.)
 428         * Makefile.in:  Add stuff for new foo.xn scripts.
 429         These are generated by replacing "ALIGN(0x...00)" by ".".
 430
 431 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 432
 433         * Makefile.in: new targets ld.ms, ld-index.ms
 434         ld.texinfo: remove tabs, other cleanups for texi2roff
 435
 436 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 437
 438         * ldmain.c (main): Make config.magic_demand_paged be true
 439         by default.  Don't the WP_TEXT and D_PAGED flags of
 440         output_bfd here; it's too late, so set it when output_bfd
 441         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 442         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 443         * ldlang.c: Remove some duplicate extern declarations.
 444         * ldgram.y: Fixes to -N and -n options.
 445         * Makefile.in:  Recognize upper case letters in sed script
 446         to remove assignments from script files.
 447         * ldtemplate:  Don't assukme that -N or -n options
 448         imply use of -r script.
 449         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 450
 451 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 452
 453         * ldtemplate: include bfd.h before sysdep.h.
 454
 455 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 456
 457         Restructure configuration scheme for bfd, binutils, ld.
 458
 459         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 460         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 461         Change some config names to match other dirs.
 462         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 463         get defined first.
 464         * config/:  Rename some config files to match up h-*.h names.
 465         Remove all the HOST_SYS definitions from the config files.
 466
 467 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 468
 469         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 470         * ldtemplate: Remove ldfile_add_library_path calls;
 471         just use the SEARCH_DIR commands in the script files.
 472         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 473         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 474         This is primarily intended for cross-linking, where you would
 475         place libaries in a different place than native libraries.
 476         Also, emulations made from ldtemplate now use $(srcdir).
 477         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 478         form; people can use the Makefile's LIB_PATH to override.
 479
 480 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 481
 482         * Makefile.in: fix target ld.dvi, add target ld.info
 483         ld.texinfo: make info filename ld.info
 484
 485 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
 486
 487         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
 488         Make).
 489         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
 490         few BFD types & enums.
