   2
   3         * relax.c (build_it): don't allocate space in the output file for
   4         stuff if -R flag applys to it.
   5         * ldfile.c: merge in VMS filename support
   6         * ldmain.c (main): take out ./ from library path, and close file
   7         before unlinking. Make multiple defs of a symbol create an
   8         unexecable file.
   9         * ldmisc.c: fatal errosrs delete output file

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

  58
  59         * Makefile.in: rework CFLAGS so that they can be passed on the

  79
  80         * Makefile.in (install): Install second copy in $(tooldir)/bin

  84
  85         * ldlex.l, ldgram.y, ldlex.h: Rewrote lexer. Now it's much nicer.

 150
 151 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
 152
 153         * Makefile.in:  Change mkscript rule into one for ./mkscript
 154         (for the sake of makes that don't realize they're the same).

 156         * genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.
 157
 158 Mon Feb 17 12:04:36 1992  Per Bothner  (bothner at cygnus.com)
 159
 160         * Makefile.in, and new files hp300bsd.sh, config/mh-hp300bsd,

 162
 163 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 164
 165         Major rewrite of how ld is configured.  The major idea
 166         is to use shell scripts to generate everything.
 167         * generic.em replaces ldtemplate.
 168         * Other *.em files replace various *.c files.
 169         A *.em file is a shell script that generates the corresponding
 170         ld__*.c file that implements an emulation.  This is usually
 171         a straight 'cat' of a here-document, possibly with substitutions.
 172         * Script files (*.sc) are places by *.sc-sh scripts.
 173         Again, these are simple shell scripts that 'cat'
 174         here-documents, usually with some substitutions.
 175         The output a *.sc-sh is a script file.
 176         * Each emulation is defined by a short shell script with
 177         extension *.sh that specifies the emulation-specific
 178         parameters (such as the name of the *.sh-sc and *.em
 179         files to use).
 180         * genscript.sh is the master shell script used to generate
 181         an emulation.  It is passed various argument, including
 182         the name a the emulation-speciic *.sh file that it
 183         "sources" to set variables to emulation-specifc parameters.
 184         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 185         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 186         * config/mh-foo:  Rename LDEMULATION names as appropriate
 187         (usually 'gldfoo' -> plain 'foo').
 188         * ldwrite.c:  Fixed a typo in a comment.
 189         * Makefile.in:  Major changes.  Removed some the sed
 190         magic to converts scripts, since that is now handled
 191         by genscripts.sh and the *.sc-sh scipt generators.
 192         * config.h:  Remove a bunch of macros defining emulations
 193         and targets.  This becomes one less file to edit when
 194         adding emulations or targets.
 195         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 196         emulation_name and target_name fields.
 197         * ldemul.c, ldemul.h:  Define some default functions used
 198         by most emulations (and remove from the *.em scripts).
 199         * ldemul.c (ldemul_choose_target):  Search the new
 200         ld_emulations array using a loop (instead of a hardwired
 201         nested if statement).
 202         Define the ld_emulation from the automatically-geenrated
 203         ldemul-list.h.  This means you no longer have to edit ldemul.c
 204         to add a new emulation.
 205         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 206         their expansions, since the former no longer exist.
 207         * PORTING:  A very rough first draft of a porting guide.
 208
 209         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 210         to be terminated by a new-line (instead of requiring a semicolon).
 211
 212 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 213
 214         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 215         tests for NULL pointers all over the place.
 216         * ldlang.c (lang_process): remember to relocate global symbols
 217         *after* relaxing has done it stuff.
 218
 219 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 220
 221         * config/mt-coff-h8300: use EMUL like everything else
 222         * ldlang.c: (print_padding_statement): print the right address.
 223         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms
 224
 225
 226 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 227
 228         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 229         * ldlang.c (print_data_statement): print the right address.
 230
 231 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 232
 233         * Makefile.in:  The rule for testing ld by re-linking itself
 234         via an intermediate -r link was moved to the ld1 rule
 235         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 236         which allows the bootstrap rule to work.
 237         * ldctor.c (find_constructors):  Don't create a constructor
 238         list if it is already defined (as would happen if ld is
 239         invoked by collect).
 240
 241 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 242
 243         * config/mh-sparc.h: now uses libgcc.a
 244         * ldmain.c: quit using exit
 245         * *sc: use *(COMMON) rather than [COMMON]
 246         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 247         to allow preprocessing of .l file.
 248         * Makefile.in: New ldlex.l mangling
 249         * ldexp.c (fold_binary): perform expressions with % and / in
 250         integer.
 251         * ldfile.c (open_a): open archives on VMS in a special way
 252
 253
 254 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 255
 256         * ldgram.y: map -M behave in the same way as -Map (sets file name
 257         to be "-".
 258         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 259         whether or not relaxing has been done.
 260         * ldmain.c: don't open a map file if it doesn't have a name
 261         * relax.c: all the brains have moved into bfd.
 262         * ldwrite.c: ammend comment
 263
 264 Fri Jan 24 14:23:46 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 265
 266         * Makefile.in: added relax, also made three stage go through a
 267         partial link stage.
 268         * relax.c : added
 269         * config.h: if GNU960 defined, then default emulation mode is
 270         GLD960
 271         * ldexp.h, ldexp.c: map to file hooks
 272         * ldlang.c: map to file hooks
 273         * ldgram.y: added -Map -relax
 274         * ldlex.l: added -relax, -Map
 275         * ldmain.c: open map file
 276         * ldmisc.c: support for map file
 277         * ldwrite.c: new relax magic
 278
 279 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)
 280
 281         * Makefile.in, config/tm-*.h:  Clean up make output, only
 282         pass DEFAULT_EMULATION to ldmain.c.
 283
 284 Wed Dec 18 15:02:47 1991  Per Bothner  (bothner at cygnus.com)
 285
 286         * ldver.c:  Bump to version 1.94.
 287
 288 Tue Dec 10 04:07:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 289
 290         * Makefile.in: infodir belongs in datadir.
 291
 292 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
 293
 294         * Makefile.in:  Pass -y to bison.  (Again;
 295         accidentally deleted by Rich.)
 296         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 297
 298 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 299
 300         * ldindr.h: added to contain prototypes of ldindr.c
 301         * ldfile.c: include ctype.h
 302         * ldmain.c: include the requried prototype headers
 303         * ldwrite.c: get_reloc_upper_bound has been renamed

 305
 306 Fri Dec  6 23:29:26 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 307
 308         * Makefile.in: punt "fundamental" mode because it breaks my emacs
 309           macros.  install using INSTALL_PROGRAM and INSTALL_DATA.  remove
 310           spaces following hyphens, bsd make can't cope.  added
 311           standards.text support and made it look like all the other
 312           makefiles.
 313
 314         * configure.in: configure now runs entirely in objdir so make file
 315           existence checks against ${srcdir}.  Mark this directory as
 316           target dependent.
 317
 318 Thu Dec  5 22:46:16 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 319
 320         * Makefile.in: idestdir and ddestdir go away.  Added copyrights
 321           and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
 322           and mandir now keyed off datadir by default.
 323
 324 Wed Dec  4 23:36:55 1991  Per Bothner  (bothner at cygnus.com)
 325
 326         * ldver.c:  Bumped version to 1.93.
 327         * Makefile.in:  Pass -y to bison.
 328
 329 Mon Nov 25 18:28:40 1991  Steve Chamberlain  (sac at cygnus.com)
 330
 331         * config.h: h8 is now coff, not ieee
 332         * h8300hds.sc: reflect the same
 333
 334 Thu Nov 14 19:55:09 1991  Per Bothner  (bothner at cygnus.com)
 335
 336         * ldver.c (ldversion()):  Update to 1.92.
 337         * ldctor.c: There are two places constructor sets
 338         can be defined.  One of them checked for an existing
 339         duplicate, the other didn't.  Unfortunately, the latter
 340         was called after the former ...
 341         So, factor out code for inserting a new element into
 342         constructor_name_list (after checking for a duplicate)
 343         into a new function add_constructor_name, and call
 344         it from both aforementioned places (ldlang_add_constructor
 345         and ldlang_check_for_constructors).
 346
 347 Wed Nov 13 15:17:43 1991  Per Bothner  (bothner at cygnus.com)
 348
 349         * Makefile.in:  Rename .c files generated from ldtemplate
 350         to have names starting with ld__.  This helps 'make clean'.
 351
 352 Tue Nov 12 18:36:50 1991  Steve Chamberlain  (sac at cygnus.com)
 353
 354         * Makefile.in: Take out the version number for install
 355         * m88kbcs.sc: put in contructor blocks.

 357 Mon Nov 11 18:47:33 1991  Per Bothner  (bothner at cygnus.com)
 358
 359         * ldmisc.c, ldmisc.h:  Re-write info() to take a filename
 360         parameter, a format, and an arg pointer, and rename it to
 361         vfinfo().  Write info() in terms of new vfinfo().
 362         New einfo() is the same as info(), except it writes to stderr.
 363         * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
 364         ldmisc.c:  Replace "error" calls to info() by new einfo().

 367
 368         * ldlex.l ldgram.y: made -V option do same as -v
 369         * Makefile.in: Added $(MINUS_G) flag so debugging can be
 370         turned off
 371
 372 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
 373          i386 aout changes from Bob Kukura
 374         * Makefile.in, config.h: added i386aout support
 375         * configure.in: fixed /h-{myhost} typo
 376         * ldgram.y: -MM now gives more boring map.
 377         * ldlang.c: now does D_PAGED flag the right way.
 378         * ldsym.c: -MM flags does the right thing.
 379
 380 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
 381
 382         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 383         * ldlang.c (init_os):  Compensate for BFD change,
 384         where bfd_make_section now returns NULL for a duplicate
 385         section request, instead of the old section.
 386
 387 Thu Oct 17 15:27:13 1991  Per Bothner  (bothner at cygnus.com)
 388
 389         * ldver.c: Bump to version 1.91 (consistent with binutils).
 390
 391 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)
 392
 393         * Makefile.in, config.h, ld.h, ldemul.c, ldexp.c, ldexp.h,
 394         ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
 395         ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
 396         ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
 397         Add or update copyright notices.
 398
 399 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 400
 401         * README: New file.
 402         * Makefile.in:  Changed installation directory name scheme
 403         to be consistent with gcc.  Also changed 'install'.
 404
 405 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 406
 407         * Makefile.in: new targets ld.mm, ld.me
 408
 409 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 410
 411         * Makefile.in, ldtemplate:  Need to use separate scripts
 412         for -n and -N options.  Yet more complication.
 413
 414 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 415
 416         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 417         work).  Add some lines to avoid Sun Make VPATH bugs.
 418
 419 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 420
 421         * news.sc: Add alignment for data segment.
 422         * ldtemplate: Add (yet another) script to get for -n or -N
 423         options.  (These need different alignment than ZMAGIC files.)
 424         * Makefile.in:  Add stuff for new foo.xn scripts.
 425         These are generated by replacing "ALIGN(0x...00)" by ".".
 426
 427 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 428
 429         * Makefile.in: new targets ld.ms, ld-index.ms
 430         ld.texinfo: remove tabs, other cleanups for texi2roff
 431
 432 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 433
 434         * ldmain.c (main): Make config.magic_demand_paged be true
 435         by default.  Don't the WP_TEXT and D_PAGED flags of
 436         output_bfd here; it's too late, so set it when output_bfd
 437         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 438         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 439         * ldlang.c: Remove some duplicate extern declarations.
 440         * ldgram.y: Fixes to -N and -n options.
 441         * Makefile.in:  Recognize upper case letters in sed script
 442         to remove assignments from script files.
 443         * ldtemplate:  Don't assukme that -N or -n options
 444         imply use of -r script.
 445         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 446
 447 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 448
 449         * ldtemplate: include bfd.h before sysdep.h.
 450
 451 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 452
 453         Restructure configuration scheme for bfd, binutils, ld.
 454
 455         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 456         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 457         Change some config names to match other dirs.
 458         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 459         get defined first.
 460         * config/:  Rename some config files to match up h-*.h names.
 461         Remove all the HOST_SYS definitions from the config files.
 462
 463 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 464
 465         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 466         * ldtemplate: Remove ldfile_add_library_path calls;
 467         just use the SEARCH_DIR commands in the script files.
 468         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 469         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 470         This is primarily intended for cross-linking, where you would
 471         place libaries in a different place than native libraries.
 472         Also, emulations made from ldtemplate now use $(srcdir).
 473         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 474         form; people can use the Makefile's LIB_PATH to override.
 475
 476 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 477
 478         * Makefile.in: fix target ld.dvi, add target ld.info
 479         ld.texinfo: make info filename ld.info
 480
 481 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
 482
 483         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
 484         Make).
 485         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
 486         few BFD types & enums.
