  58
  59         * Makefile.in (install): Install second copy in $(tooldir)/bin

  63
  64         * ldlex.l, ldgram.y, ldlex.h: Rewrote lexer. Now it's much nicer.

 129
 130 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
 131
 132         * Makefile.in:  Change mkscript rule into one for ./mkscript
 133         (for the sake of makes that don't realize they're the same).
 134         * PORTING:  Add more details.
 135         * genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.
 136
 137 Mon Feb 17 12:04:36 1992  Per Bothner  (bothner at cygnus.com)
 138
 139         * Makefile.in, and new files hp300bsd.sh, config/mh-hp300bsd,

 141
 142 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 143
 144         Major rewrite of how ld is configured.  The major idea
 145         is to use shell scripts to generate everything.
 146         * generic.em replaces ldtemplate.
 147         * Other *.em files replace various *.c files.
 148         A *.em file is a shell script that generates the corresponding
 149         ld__*.c file that implements an emulation.  This is usually
 150         a straight 'cat' of a here-document, possibly with substitutions.
 151         * Script files (*.sc) are places by *.sc-sh scripts.
 152         Again, these are simple shell scripts that 'cat'
 153         here-documents, usually with some substitutions.
 154         The output a *.sc-sh is a script file.
 155         * Each emulation is defined by a short shell script with
 156         extension *.sh that specifies the emulation-specific
 157         parameters (such as the name of the *.sh-sc and *.em
 158         files to use).
 159         * genscript.sh is the master shell script used to generate
 160         an emulation.  It is passed various argument, including
 161         the name a the emulation-speciic *.sh file that it
 162         "sources" to set variables to emulation-specifc parameters.
 163         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 164         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 165         * config/mh-foo:  Rename LDEMULATION names as appropriate
 166         (usually 'gldfoo' -> plain 'foo').
 167         * ldwrite.c:  Fixed a typo in a comment.
 168         * Makefile.in:  Major changes.  Removed some the sed
 169         magic to converts scripts, since that is now handled
 170         by genscripts.sh and the *.sc-sh scipt generators.
 171         * config.h:  Remove a bunch of macros defining emulations
 172         and targets.  This becomes one less file to edit when
 173         adding emulations or targets.
 174         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 175         emulation_name and target_name fields.
 176         * ldemul.c, ldemul.h:  Define some default functions used
 177         by most emulations (and remove from the *.em scripts).
 178         * ldemul.c (ldemul_choose_target):  Search the new
 179         ld_emulations array using a loop (instead of a hardwired
 180         nested if statement).
 181         Define the ld_emulation from the automatically-geenrated
 182         ldemul-list.h.  This means you no longer have to edit ldemul.c
 183         to add a new emulation.
 184         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 185         their expansions, since the former no longer exist.
 186         * PORTING:  A very rough first draft of a porting guide.
 187
 188         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 189         to be terminated by a new-line (instead of requiring a semicolon).
 190
 191 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 192
 193         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 194         tests for NULL pointers all over the place.
 195         * ldlang.c (lang_process): remember to relocate global symbols
 196         *after* relaxing has done it stuff.
 197
 198 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 199
 200         * config/mt-coff-h8300: use EMUL like everything else
 201         * ldlang.c: (print_padding_statement): print the right address.
 202         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms
 203
 204
 205 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 206
 207         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 208         * ldlang.c (print_data_statement): print the right address.
 209
 210 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 211
 212         * Makefile.in:  The rule for testing ld by re-linking itself
 213         via an intermediate -r link was moved to the ld1 rule
 214         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 215         which allows the bootstrap rule to work.
 216         * ldctor.c (find_constructors):  Don't create a constructor
 217         list if it is already defined (as would happen if ld is
 218         invoked by collect).
 219
 220 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 221
 222         * config/mh-sparc.h: now uses libgcc.a
 223         * ldmain.c: quit using exit
 224         * *sc: use *(COMMON) rather than [COMMON]
 225         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 226         to allow preprocessing of .l file.
 227         * Makefile.in: New ldlex.l mangling
 228         * ldexp.c (fold_binary): perform expressions with % and / in
 229         integer.
 230         * ldfile.c (open_a): open archives on VMS in a special way
 231
 232
 233 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 234
 235         * ldgram.y: map -M behave in the same way as -Map (sets file name
 236         to be "-".
 237         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 238         whether or not relaxing has been done.
 239         * ldmain.c: don't open a map file if it doesn't have a name
 240         * relax.c: all the brains have moved into bfd.
 241         * ldwrite.c: ammend comment
 242
 243 Fri Jan 24 14:23:46 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 244
 245         * Makefile.in: added relax, also made three stage go through a
 246         partial link stage.
 247         * relax.c : added
 248         * config.h: if GNU960 defined, then default emulation mode is
 249         GLD960
 250         * ldexp.h, ldexp.c: map to file hooks
 251         * ldlang.c: map to file hooks
 252         * ldgram.y: added -Map -relax
 253         * ldlex.l: added -relax, -Map
 254         * ldmain.c: open map file
 255         * ldmisc.c: support for map file
 256         * ldwrite.c: new relax magic
 257
 258 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)
 259
 260         * Makefile.in, config/tm-*.h:  Clean up make output, only
 261         pass DEFAULT_EMULATION to ldmain.c.
 262
 263 Wed Dec 18 15:02:47 1991  Per Bothner  (bothner at cygnus.com)
 264
 265         * ldver.c:  Bump to version 1.94.
 266
 267 Tue Dec 10 04:07:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 268
 269         * Makefile.in: infodir belongs in datadir.
 270
 271 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
 272
 273         * Makefile.in:  Pass -y to bison.  (Again;
 274         accidentally deleted by Rich.)
 275         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 276
 277 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 278
 279         * ldindr.h: added to contain prototypes of ldindr.c
 280         * ldfile.c: include ctype.h
 281         * ldmain.c: include the requried prototype headers
 282         * ldwrite.c: get_reloc_upper_bound has been renamed

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

 352          i386 aout changes from Bob Kukura
 353         * Makefile.in, config.h: added i386aout support
 354         * configure.in: fixed /h-{myhost} typo
 355         * ldgram.y: -MM now gives more boring map.
 356         * ldlang.c: now does D_PAGED flag the right way.
 357         * ldsym.c: -MM flags does the right thing.

 359 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
 360
 361         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 362         * ldlang.c (init_os):  Compensate for BFD change,
 363         where bfd_make_section now returns NULL for a duplicate
 364         section request, instead of the old section.

 366 Thu Oct 17 15:27:13 1991  Per Bothner  (bothner at cygnus.com)
 367
 368         * ldver.c: Bump to version 1.91 (consistent with binutils).
 369

 377
 378 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 379
 380         * README: New file.
 381         * Makefile.in:  Changed installation directory name scheme
 382         to be consistent with gcc.  Also changed 'install'.
 383
 384 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 385
 386         * Makefile.in: new targets ld.mm, ld.me
 387
 388 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 389
 390         * Makefile.in, ldtemplate:  Need to use separate scripts
 391         for -n and -N options.  Yet more complication.
 392
 393 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 394
 395         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 396         work).  Add some lines to avoid Sun Make VPATH bugs.
 397
 398 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 399
 400         * news.sc: Add alignment for data segment.
 401         * ldtemplate: Add (yet another) script to get for -n or -N
 402         options.  (These need different alignment than ZMAGIC files.)
 403         * Makefile.in:  Add stuff for new foo.xn scripts.
 404         These are generated by replacing "ALIGN(0x...00)" by ".".
 405
 406 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 407
 408         * Makefile.in: new targets ld.ms, ld-index.ms
 409         ld.texinfo: remove tabs, other cleanups for texi2roff
 410
 411 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 412
 413         * ldmain.c (main): Make config.magic_demand_paged be true
 414         by default.  Don't the WP_TEXT and D_PAGED flags of
 415         output_bfd here; it's too late, so set it when output_bfd
 416         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 417         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 418         * ldlang.c: Remove some duplicate extern declarations.
 419         * ldgram.y: Fixes to -N and -n options.
 420         * Makefile.in:  Recognize upper case letters in sed script
 421         to remove assignments from script files.
 422         * ldtemplate:  Don't assukme that -N or -n options
 423         imply use of -r script.
 424         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 425
 426 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 427
 428         * ldtemplate: include bfd.h before sysdep.h.
 429
 430 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 431
 432         Restructure configuration scheme for bfd, binutils, ld.
 433
 434         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 435         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 436         Change some config names to match other dirs.
 437         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 438         get defined first.
 439         * config/:  Rename some config files to match up h-*.h names.
 440         Remove all the HOST_SYS definitions from the config files.
 441
 442 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 443
 444         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 445         * ldtemplate: Remove ldfile_add_library_path calls;
 446         just use the SEARCH_DIR commands in the script files.
 447         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 448         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 449         This is primarily intended for cross-linking, where you would
 450         place libaries in a different place than native libraries.
 451         Also, emulations made from ldtemplate now use $(srcdir).
 452         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 453         form; people can use the Makefile's LIB_PATH to override.
 454
 455 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 456
 457         * Makefile.in: fix target ld.dvi, add target ld.info
 458         ld.texinfo: make info filename ld.info
 459
 460 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
 461
 462         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
 463         Make).
 464         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
 465         few BFD types & enums.
