  69
  70         * Makefile.in (install): Install second copy in $(tooldir)/bin

  74
  75         * ldlex.l, ldgram.y, ldlex.h: Rewrote lexer. Now it's much nicer.

 140
 141 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
 142
 143         * Makefile.in:  Change mkscript rule into one for ./mkscript
 144         (for the sake of makes that don't realize they're the same).

 146         * genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.
 147
 148 Mon Feb 17 12:04:36 1992  Per Bothner  (bothner at cygnus.com)
 149
 150         * Makefile.in, and new files hp300bsd.sh, config/mh-hp300bsd,

 153 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 154
 155         Major rewrite of how ld is configured.  The major idea
 156         is to use shell scripts to generate everything.
 157         * generic.em replaces ldtemplate.
 158         * Other *.em files replace various *.c files.
 159         A *.em file is a shell script that generates the corresponding
 160         ld__*.c file that implements an emulation.  This is usually
 161         a straight 'cat' of a here-document, possibly with substitutions.
 162         * Script files (*.sc) are places by *.sc-sh scripts.
 163         Again, these are simple shell scripts that 'cat'
 164         here-documents, usually with some substitutions.
 165         The output a *.sc-sh is a script file.
 166         * Each emulation is defined by a short shell script with
 167         extension *.sh that specifies the emulation-specific
 168         parameters (such as the name of the *.sh-sc and *.em
 169         files to use).
 170         * genscript.sh is the master shell script used to generate
 171         an emulation.  It is passed various argument, including
 172         the name a the emulation-speciic *.sh file that it
 173         "sources" to set variables to emulation-specifc parameters.
 174         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 175         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 176         * config/mh-foo:  Rename LDEMULATION names as appropriate
 177         (usually 'gldfoo' -> plain 'foo').
 178         * ldwrite.c:  Fixed a typo in a comment.
 179         * Makefile.in:  Major changes.  Removed some the sed
 180         magic to converts scripts, since that is now handled
 181         by genscripts.sh and the *.sc-sh scipt generators.
 182         * config.h:  Remove a bunch of macros defining emulations
 183         and targets.  This becomes one less file to edit when
 184         adding emulations or targets.
 185         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 186         emulation_name and target_name fields.
 187         * ldemul.c, ldemul.h:  Define some default functions used
 188         by most emulations (and remove from the *.em scripts).
 189         * ldemul.c (ldemul_choose_target):  Search the new
 190         ld_emulations array using a loop (instead of a hardwired
 191         nested if statement).
 192         Define the ld_emulation from the automatically-geenrated
 193         ldemul-list.h.  This means you no longer have to edit ldemul.c
 194         to add a new emulation.
 195         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 196         their expansions, since the former no longer exist.
 197         * PORTING:  A very rough first draft of a porting guide.
 198
 199         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 200         to be terminated by a new-line (instead of requiring a semicolon).
 201
 202 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 203
 204         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 205         tests for NULL pointers all over the place.
 206         * ldlang.c (lang_process): remember to relocate global symbols
 207         *after* relaxing has done it stuff.
 208
 209 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 210
 211         * config/mt-coff-h8300: use EMUL like everything else
 212         * ldlang.c: (print_padding_statement): print the right address.
 213         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms
 214
 215
 216 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 217
 218         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 219         * ldlang.c (print_data_statement): print the right address.
 220
 221 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 222
 223         * Makefile.in:  The rule for testing ld by re-linking itself
 224         via an intermediate -r link was moved to the ld1 rule
 225         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 226         which allows the bootstrap rule to work.
 227         * ldctor.c (find_constructors):  Don't create a constructor
 228         list if it is already defined (as would happen if ld is
 229         invoked by collect).
 230
 231 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 232
 233         * config/mh-sparc.h: now uses libgcc.a
 234         * ldmain.c: quit using exit
 235         * *sc: use *(COMMON) rather than [COMMON]
 236         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 237         to allow preprocessing of .l file.
 238         * Makefile.in: New ldlex.l mangling
 239         * ldexp.c (fold_binary): perform expressions with % and / in
 240         integer.
 241         * ldfile.c (open_a): open archives on VMS in a special way
 242
 243
 244 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 245
 246         * ldgram.y: map -M behave in the same way as -Map (sets file name
 247         to be "-".
 248         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 249         whether or not relaxing has been done.
 250         * ldmain.c: don't open a map file if it doesn't have a name
 251         * relax.c: all the brains have moved into bfd.
 252         * ldwrite.c: ammend comment
 253
 254 Fri Jan 24 14:23:46 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 255
 256         * Makefile.in: added relax, also made three stage go through a
 257         partial link stage.
 258         * relax.c : added
 259         * config.h: if GNU960 defined, then default emulation mode is
 260         GLD960
 261         * ldexp.h, ldexp.c: map to file hooks
 262         * ldlang.c: map to file hooks
 263         * ldgram.y: added -Map -relax
 264         * ldlex.l: added -relax, -Map
 265         * ldmain.c: open map file
 266         * ldmisc.c: support for map file
 267         * ldwrite.c: new relax magic
 268
 269 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)
 270
 271         * Makefile.in, config/tm-*.h:  Clean up make output, only
 272         pass DEFAULT_EMULATION to ldmain.c.
 273
 274 Wed Dec 18 15:02:47 1991  Per Bothner  (bothner at cygnus.com)
 275
 276         * ldver.c:  Bump to version 1.94.
 277
 278 Tue Dec 10 04:07:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 279
 280         * Makefile.in: infodir belongs in datadir.
 281
 282 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
 283
 284         * Makefile.in:  Pass -y to bison.  (Again;
 285         accidentally deleted by Rich.)
 286         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 287
 288 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 289
 290         * ldindr.h: added to contain prototypes of ldindr.c
 291         * ldfile.c: include ctype.h
 292         * ldmain.c: include the requried prototype headers

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

 357
 358         * ldlex.l ldgram.y: made -V option do same as -v
 359         * Makefile.in: Added $(MINUS_G) flag so debugging can be
 360         turned off
 361
 362 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
 363          i386 aout changes from Bob Kukura
 364         * Makefile.in, config.h: added i386aout support
 365         * configure.in: fixed /h-{myhost} typo
 366         * ldgram.y: -MM now gives more boring map.
 367         * ldlang.c: now does D_PAGED flag the right way.
 368         * ldsym.c: -MM flags does the right thing.
 369
 370 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
 371
 372         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 373         * ldlang.c (init_os):  Compensate for BFD change,
 374         where bfd_make_section now returns NULL for a duplicate
 375         section request, instead of the old section.
 376
 377 Thu Oct 17 15:27:13 1991  Per Bothner  (bothner at cygnus.com)
 378
 379         * ldver.c: Bump to version 1.91 (consistent with binutils).
 380
 381 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)
 382
 383         * Makefile.in, config.h, ld.h, ldemul.c, ldexp.c, ldexp.h,
 384         ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
 385         ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
 386         ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
 387         Add or update copyright notices.
 388
 389 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 390
 391         * README: New file.
 392         * Makefile.in:  Changed installation directory name scheme
 393         to be consistent with gcc.  Also changed 'install'.
 394
 395 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 396
 397         * Makefile.in: new targets ld.mm, ld.me
 398
 399 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 400
 401         * Makefile.in, ldtemplate:  Need to use separate scripts
 402         for -n and -N options.  Yet more complication.
 403
 404 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 405
 406         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 407         work).  Add some lines to avoid Sun Make VPATH bugs.
 408
 409 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 410
 411         * news.sc: Add alignment for data segment.
 412         * ldtemplate: Add (yet another) script to get for -n or -N
 413         options.  (These need different alignment than ZMAGIC files.)
 414         * Makefile.in:  Add stuff for new foo.xn scripts.
 415         These are generated by replacing "ALIGN(0x...00)" by ".".
 416
 417 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 418
 419         * Makefile.in: new targets ld.ms, ld-index.ms
 420         ld.texinfo: remove tabs, other cleanups for texi2roff
 421
 422 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 423
 424         * ldmain.c (main): Make config.magic_demand_paged be true
 425         by default.  Don't the WP_TEXT and D_PAGED flags of
 426         output_bfd here; it's too late, so set it when output_bfd
 427         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 428         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 429         * ldlang.c: Remove some duplicate extern declarations.
 430         * ldgram.y: Fixes to -N and -n options.
 431         * Makefile.in:  Recognize upper case letters in sed script
 432         to remove assignments from script files.
 433         * ldtemplate:  Don't assukme that -N or -n options
 434         imply use of -r script.
 435         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 436
 437 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 438
 439         * ldtemplate: include bfd.h before sysdep.h.
 440
 441 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 442
 443         Restructure configuration scheme for bfd, binutils, ld.
 444
 445         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 446         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 447         Change some config names to match other dirs.
 448         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 449         get defined first.
 450         * config/:  Rename some config files to match up h-*.h names.
 451         Remove all the HOST_SYS definitions from the config files.
 452
 453 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 454
 455         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 456         * ldtemplate: Remove ldfile_add_library_path calls;
 457         just use the SEARCH_DIR commands in the script files.
 458         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 459         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 460         This is primarily intended for cross-linking, where you would
 461         place libaries in a different place than native libraries.
 462         Also, emulations made from ldtemplate now use $(srcdir).
 463         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 464         form; people can use the Makefile's LIB_PATH to override.
 465
 466 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 467
 468         * Makefile.in: fix target ld.dvi, add target ld.info
 469         ld.texinfo: make info filename ld.info
 470
 471 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
 472
 473         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
 474         Make).
 475         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
 476         few BFD types & enums.
