   5         * ldexp.c, ldlang.c: now build memory shape tree in obstacks
   6         rather than with raw malloc, makes it easier to track where memory
   7         is going.

  53
  54         * Makefile.in (install): Install second copy in $(tooldir)/bin

 125 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
 126
 127         * Makefile.in:  Change mkscript rule into one for ./mkscript
 128         (for the sake of makes that don't realize they're the same).

 130         * genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.
 131
 132 Mon Feb 17 12:04:36 1992  Per Bothner  (bothner at cygnus.com)
 133
 134         * Makefile.in, and new files hp300bsd.sh, config/mh-hp300bsd,

 137 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 138
 139         Major rewrite of how ld is configured.  The major idea
 140         is to use shell scripts to generate everything.
 141         * generic.em replaces ldtemplate.
 142         * Other *.em files replace various *.c files.
 143         A *.em file is a shell script that generates the corresponding
 144         ld__*.c file that implements an emulation.  This is usually
 145         a straight 'cat' of a here-document, possibly with substitutions.
 146         * Script files (*.sc) are places by *.sc-sh scripts.
 147         Again, these are simple shell scripts that 'cat'
 148         here-documents, usually with some substitutions.
 149         The output a *.sc-sh is a script file.
 150         * Each emulation is defined by a short shell script with
 151         extension *.sh that specifies the emulation-specific
 152         parameters (such as the name of the *.sh-sc and *.em
 153         files to use).
 154         * genscript.sh is the master shell script used to generate
 155         an emulation.  It is passed various argument, including
 156         the name a the emulation-speciic *.sh file that it
 157         "sources" to set variables to emulation-specifc parameters.
 158         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 159         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 160         * config/mh-foo:  Rename LDEMULATION names as appropriate
 161         (usually 'gldfoo' -> plain 'foo').
 162         * ldwrite.c:  Fixed a typo in a comment.
 163         * Makefile.in:  Major changes.  Removed some the sed
 164         magic to converts scripts, since that is now handled
 165         by genscripts.sh and the *.sc-sh scipt generators.
 166         * config.h:  Remove a bunch of macros defining emulations
 167         and targets.  This becomes one less file to edit when
 168         adding emulations or targets.
 169         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 170         emulation_name and target_name fields.
 171         * ldemul.c, ldemul.h:  Define some default functions used
 172         by most emulations (and remove from the *.em scripts).
 173         * ldemul.c (ldemul_choose_target):  Search the new
 174         ld_emulations array using a loop (instead of a hardwired
 175         nested if statement).
 176         Define the ld_emulation from the automatically-geenrated
 177         ldemul-list.h.  This means you no longer have to edit ldemul.c
 178         to add a new emulation.
 179         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 180         their expansions, since the former no longer exist.
 181         * PORTING:  A very rough first draft of a porting guide.
 182
 183         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 184         to be terminated by a new-line (instead of requiring a semicolon).
 185
 186 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 187
 188         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 189         tests for NULL pointers all over the place.
 190         * ldlang.c (lang_process): remember to relocate global symbols
 191         *after* relaxing has done it stuff.
 192
 193 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 194
 195         * config/mt-coff-h8300: use EMUL like everything else
 196         * ldlang.c: (print_padding_statement): print the right address.
 197         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms
 198
 199
 200 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 201
 202         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 203         * ldlang.c (print_data_statement): print the right address.
 204
 205 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 206
 207         * Makefile.in:  The rule for testing ld by re-linking itself
 208         via an intermediate -r link was moved to the ld1 rule
 209         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 210         which allows the bootstrap rule to work.
 211         * ldctor.c (find_constructors):  Don't create a constructor
 212         list if it is already defined (as would happen if ld is
 213         invoked by collect).
 214
 215 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 216
 217         * config/mh-sparc.h: now uses libgcc.a
 218         * ldmain.c: quit using exit
 219         * *sc: use *(COMMON) rather than [COMMON]
 220         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 221         to allow preprocessing of .l file.
 222         * Makefile.in: New ldlex.l mangling
 223         * ldexp.c (fold_binary): perform expressions with % and / in
 224         integer.
 225         * ldfile.c (open_a): open archives on VMS in a special way
 226
 227
 228 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 229
 230         * ldgram.y: map -M behave in the same way as -Map (sets file name
 231         to be "-".
 232         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 233         whether or not relaxing has been done.
 234         * ldmain.c: don't open a map file if it doesn't have a name
 235         * relax.c: all the brains have moved into bfd.
 236         * ldwrite.c: ammend comment
 237
 238 Fri Jan 24 14:23:46 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 239
 240         * Makefile.in: added relax, also made three stage go through a
 241         partial link stage.
 242         * relax.c : added
 243         * config.h: if GNU960 defined, then default emulation mode is
 244         GLD960
 245         * ldexp.h, ldexp.c: map to file hooks
 246         * ldlang.c: map to file hooks
 247         * ldgram.y: added -Map -relax
 248         * ldlex.l: added -relax, -Map
 249         * ldmain.c: open map file
 250         * ldmisc.c: support for map file
 251         * ldwrite.c: new relax magic
 252
 253 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)
 254
 255         * Makefile.in, config/tm-*.h:  Clean up make output, only
 256         pass DEFAULT_EMULATION to ldmain.c.
 257

 259
 260         * ldver.c:  Bump to version 1.94.
 261
 262 Tue Dec 10 04:07:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 263
 264         * Makefile.in: infodir belongs in datadir.
 265
 266 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
 267
 268         * Makefile.in:  Pass -y to bison.  (Again;
 269         accidentally deleted by Rich.)
 270         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 271
 272 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 273
 274         * ldindr.h: added to contain prototypes of ldindr.c
 275         * ldfile.c: include ctype.h
 276         * ldmain.c: include the requried prototype headers
 277         * ldwrite.c: get_reloc_upper_bound has been renamed

 279
 280 Fri Dec  6 23:29:26 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 281
 282         * Makefile.in: punt "fundamental" mode because it breaks my emacs
 283           macros.  install using INSTALL_PROGRAM and INSTALL_DATA.  remove
 284           spaces following hyphens, bsd make can't cope.  added
 285           standards.text support and made it look like all the other
 286           makefiles.
 287
 288         * configure.in: configure now runs entirely in objdir so make file
 289           existence checks against ${srcdir}.  Mark this directory as
 290           target dependent.
 291
 292 Thu Dec  5 22:46:16 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 293
 294         * Makefile.in: idestdir and ddestdir go away.  Added copyrights
 295           and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
 296           and mandir now keyed off datadir by default.
 297
 298 Wed Dec  4 23:36:55 1991  Per Bothner  (bothner at cygnus.com)
 299
 300         * ldver.c:  Bumped version to 1.93.
 301         * Makefile.in:  Pass -y to bison.
 302
 303 Mon Nov 25 18:28:40 1991  Steve Chamberlain  (sac at cygnus.com)
 304
 305         * config.h: h8 is now coff, not ieee
 306         * h8300hds.sc: reflect the same
 307
 308 Thu Nov 14 19:55:09 1991  Per Bothner  (bothner at cygnus.com)
 309
 310         * ldver.c (ldversion()):  Update to 1.92.
 311         * ldctor.c: There are two places constructor sets
 312         can be defined.  One of them checked for an existing
 313         duplicate, the other didn't.  Unfortunately, the latter
 314         was called after the former ...
 315         So, factor out code for inserting a new element into
 316         constructor_name_list (after checking for a duplicate)
 317         into a new function add_constructor_name, and call
 318         it from both aforementioned places (ldlang_add_constructor
 319         and ldlang_check_for_constructors).
 320
 321 Wed Nov 13 15:17:43 1991  Per Bothner  (bothner at cygnus.com)
 322
 323         * Makefile.in:  Rename .c files generated from ldtemplate
 324         to have names starting with ld__.  This helps 'make clean'.
 325
 326 Tue Nov 12 18:36:50 1991  Steve Chamberlain  (sac at cygnus.com)
 327
 328         * Makefile.in: Take out the version number for install
 329         * m88kbcs.sc: put in contructor blocks.
 330
 331 Mon Nov 11 18:47:33 1991  Per Bothner  (bothner at cygnus.com)
 332
 333         * ldmisc.c, ldmisc.h:  Re-write info() to take a filename
 334         parameter, a format, and an arg pointer, and rename it to
 335         vfinfo().  Write info() in terms of new vfinfo().
 336         New einfo() is the same as info(), except it writes to stderr.
 337         * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
 338         ldmisc.c:  Replace "error" calls to info() by new einfo().
 339
 340 Mon Nov 11 09:57:32 1991  Steve Chamberlain  (steve at cygnus.com)
 341
 342         * ldlex.l ldgram.y: made -V option do same as -v
 343         * Makefile.in: Added $(MINUS_G) flag so debugging can be
 344         turned off
 345
 346 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
 347          i386 aout changes from Bob Kukura
 348         * Makefile.in, config.h: added i386aout support
 349         * configure.in: fixed /h-{myhost} typo
 350         * ldgram.y: -MM now gives more boring map.
 351         * ldlang.c: now does D_PAGED flag the right way.
 352         * ldsym.c: -MM flags does the right thing.

 355
 356         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 357         * ldlang.c (init_os):  Compensate for BFD change,
 358         where bfd_make_section now returns NULL for a duplicate
 359         section request, instead of the old section.

 362
 363         * ldver.c: Bump to version 1.91 (consistent with binutils).
 364
 365 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)
 366

 368         ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
 369         ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
 370         ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
 371         Add or update copyright notices.
 372
 373 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 374
 375         * README: New file.
 376         * Makefile.in:  Changed installation directory name scheme
 377         to be consistent with gcc.  Also changed 'install'.
 378
 379 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 380
 381         * Makefile.in: new targets ld.mm, ld.me
 382
 383 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 384
 385         * Makefile.in, ldtemplate:  Need to use separate scripts
 386         for -n and -N options.  Yet more complication.
 387
 388 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 389
 390         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 391         work).  Add some lines to avoid Sun Make VPATH bugs.
 392
 393 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 394
 395         * news.sc: Add alignment for data segment.
 396         * ldtemplate: Add (yet another) script to get for -n or -N
 397         options.  (These need different alignment than ZMAGIC files.)
 398         * Makefile.in:  Add stuff for new foo.xn scripts.
 399         These are generated by replacing "ALIGN(0x...00)" by ".".

 401 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 402
 403         * Makefile.in: new targets ld.ms, ld-index.ms
 404         ld.texinfo: remove tabs, other cleanups for texi2roff
 405
 406 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 407
 408         * ldmain.c (main): Make config.magic_demand_paged be true
 409         by default.  Don't the WP_TEXT and D_PAGED flags of
 410         output_bfd here; it's too late, so set it when output_bfd
 411         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 412         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 413         * ldlang.c: Remove some duplicate extern declarations.
 414         * ldgram.y: Fixes to -N and -n options.
 415         * Makefile.in:  Recognize upper case letters in sed script
 416         to remove assignments from script files.
 417         * ldtemplate:  Don't assukme that -N or -n options
 418         imply use of -r script.
 419         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 420
 421 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 422
 423         * ldtemplate: include bfd.h before sysdep.h.
 424
 425 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 426
 427         Restructure configuration scheme for bfd, binutils, ld.
 428
 429         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 430         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 431         Change some config names to match other dirs.
 432         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 433         get defined first.
 434         * config/:  Rename some config files to match up h-*.h names.
 435         Remove all the HOST_SYS definitions from the config files.
 436
 437 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 438
 439         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 440         * ldtemplate: Remove ldfile_add_library_path calls;
 441         just use the SEARCH_DIR commands in the script files.
 442         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 443         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 444         This is primarily intended for cross-linking, where you would
 445         place libaries in a different place than native libraries.
 446         Also, emulations made from ldtemplate now use $(srcdir).
 447         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 448         form; people can use the Makefile's LIB_PATH to override.
 449
 450 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 451
 452         * Makefile.in: fix target ld.dvi, add target ld.info
 453         ld.texinfo: make info filename ld.info
 454
 455 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
 456
 457         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
 458         Make).
 459         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
 460         few BFD types & enums.
