  53
  54         * Makefile.in: rework CFLAGS so that they can be passed on the

  74
  75         * Makefile.in (install): Install second copy in $(tooldir)/bin

 145
 146 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
 147
 148         * Makefile.in:  Change mkscript rule into one for ./mkscript
 149         (for the sake of makes that don't realize they're the same).

 151         * genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.
 152
 153 Mon Feb 17 12:04:36 1992  Per Bothner  (bothner at cygnus.com)
 154

 158 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 159
 160         Major rewrite of how ld is configured.  The major idea
 161         is to use shell scripts to generate everything.
 162         * generic.em replaces ldtemplate.
 163         * Other *.em files replace various *.c files.
 164         A *.em file is a shell script that generates the corresponding
 165         ld__*.c file that implements an emulation.  This is usually
 166         a straight 'cat' of a here-document, possibly with substitutions.
 167         * Script files (*.sc) are places by *.sc-sh scripts.
 168         Again, these are simple shell scripts that 'cat'
 169         here-documents, usually with some substitutions.
 170         The output a *.sc-sh is a script file.
 171         * Each emulation is defined by a short shell script with
 172         extension *.sh that specifies the emulation-specific
 173         parameters (such as the name of the *.sh-sc and *.em
 174         files to use).
 175         * genscript.sh is the master shell script used to generate
 176         an emulation.  It is passed various argument, including
 177         the name a the emulation-speciic *.sh file that it
 178         "sources" to set variables to emulation-specifc parameters.
 179         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 180         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 181         * config/mh-foo:  Rename LDEMULATION names as appropriate
 182         (usually 'gldfoo' -> plain 'foo').
 183         * ldwrite.c:  Fixed a typo in a comment.
 184         * Makefile.in:  Major changes.  Removed some the sed
 185         magic to converts scripts, since that is now handled
 186         by genscripts.sh and the *.sc-sh scipt generators.
 187         * config.h:  Remove a bunch of macros defining emulations
 188         and targets.  This becomes one less file to edit when
 189         adding emulations or targets.
 190         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 191         emulation_name and target_name fields.
 192         * ldemul.c, ldemul.h:  Define some default functions used
 193         by most emulations (and remove from the *.em scripts).
 194         * ldemul.c (ldemul_choose_target):  Search the new
 195         ld_emulations array using a loop (instead of a hardwired
 196         nested if statement).
 197         Define the ld_emulation from the automatically-geenrated
 198         ldemul-list.h.  This means you no longer have to edit ldemul.c
 199         to add a new emulation.
 200         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 201         their expansions, since the former no longer exist.
 202         * PORTING:  A very rough first draft of a porting guide.
 203
 204         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 205         to be terminated by a new-line (instead of requiring a semicolon).
 206
 207 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 208
 209         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 210         tests for NULL pointers all over the place.
 211         * ldlang.c (lang_process): remember to relocate global symbols
 212         *after* relaxing has done it stuff.
 213
 214 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 215
 216         * config/mt-coff-h8300: use EMUL like everything else
 217         * ldlang.c: (print_padding_statement): print the right address.
 218         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms
 219
 220
 221 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 222
 223         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 224         * ldlang.c (print_data_statement): print the right address.
 225
 226 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 227
 228         * Makefile.in:  The rule for testing ld by re-linking itself
 229         via an intermediate -r link was moved to the ld1 rule
 230         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 231         which allows the bootstrap rule to work.
 232         * ldctor.c (find_constructors):  Don't create a constructor
 233         list if it is already defined (as would happen if ld is
 234         invoked by collect).
 235
 236 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 237
 238         * config/mh-sparc.h: now uses libgcc.a
 239         * ldmain.c: quit using exit
 240         * *sc: use *(COMMON) rather than [COMMON]
 241         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 242         to allow preprocessing of .l file.
 243         * Makefile.in: New ldlex.l mangling
 244         * ldexp.c (fold_binary): perform expressions with % and / in
 245         integer.
 246         * ldfile.c (open_a): open archives on VMS in a special way
 247
 248
 249 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 250
 251         * ldgram.y: map -M behave in the same way as -Map (sets file name
 252         to be "-".
 253         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 254         whether or not relaxing has been done.
 255         * ldmain.c: don't open a map file if it doesn't have a name
 256         * relax.c: all the brains have moved into bfd.
 257         * ldwrite.c: ammend comment
 258
 259 Fri Jan 24 14:23:46 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 260
 261         * Makefile.in: added relax, also made three stage go through a
 262         partial link stage.
 263         * relax.c : added
 264         * config.h: if GNU960 defined, then default emulation mode is
 265         GLD960
 266         * ldexp.h, ldexp.c: map to file hooks
 267         * ldlang.c: map to file hooks
 268         * ldgram.y: added -Map -relax
 269         * ldlex.l: added -relax, -Map
 270         * ldmain.c: open map file
 271         * ldmisc.c: support for map file
 272         * ldwrite.c: new relax magic
 273
 274 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)
 275
 276         * Makefile.in, config/tm-*.h:  Clean up make output, only
 277         pass DEFAULT_EMULATION to ldmain.c.
 278
 279 Wed Dec 18 15:02:47 1991  Per Bothner  (bothner at cygnus.com)
 280
 281         * ldver.c:  Bump to version 1.94.
 282
 283 Tue Dec 10 04:07:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 284
 285         * Makefile.in: infodir belongs in datadir.
 286
 287 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
 288
 289         * Makefile.in:  Pass -y to bison.  (Again;
 290         accidentally deleted by Rich.)
 291         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 292
 293 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 294
 295         * ldindr.h: added to contain prototypes of ldindr.c

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

 361 Mon Nov 11 09:57:32 1991  Steve Chamberlain  (steve at cygnus.com)
 362
 363         * ldlex.l ldgram.y: made -V option do same as -v
 364         * Makefile.in: Added $(MINUS_G) flag so debugging can be
 365         turned off
 366
 367 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
 368          i386 aout changes from Bob Kukura
 369         * Makefile.in, config.h: added i386aout support
 370         * configure.in: fixed /h-{myhost} typo
 371         * ldgram.y: -MM now gives more boring map.
 372         * ldlang.c: now does D_PAGED flag the right way.
 373         * ldsym.c: -MM flags does the right thing.
 374
 375 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
 376
 377         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 378         * ldlang.c (init_os):  Compensate for BFD change,
 379         where bfd_make_section now returns NULL for a duplicate
 380         section request, instead of the old section.
 381
 382 Thu Oct 17 15:27:13 1991  Per Bothner  (bothner at cygnus.com)
 383
 384         * ldver.c: Bump to version 1.91 (consistent with binutils).
 385
 386 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)
 387
 388         * Makefile.in, config.h, ld.h, ldemul.c, ldexp.c, ldexp.h,
 389         ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
 390         ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
 391         ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
 392         Add or update copyright notices.
 393
 394 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 395
 396         * README: New file.
 397         * Makefile.in:  Changed installation directory name scheme
 398         to be consistent with gcc.  Also changed 'install'.
 399
 400 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 401
 402         * Makefile.in: new targets ld.mm, ld.me
 403
 404 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 405
 406         * Makefile.in, ldtemplate:  Need to use separate scripts
 407         for -n and -N options.  Yet more complication.
 408
 409 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 410
 411         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 412         work).  Add some lines to avoid Sun Make VPATH bugs.
 413
 414 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 415
 416         * news.sc: Add alignment for data segment.
 417         * ldtemplate: Add (yet another) script to get for -n or -N
 418         options.  (These need different alignment than ZMAGIC files.)
 419         * Makefile.in:  Add stuff for new foo.xn scripts.
 420         These are generated by replacing "ALIGN(0x...00)" by ".".
 421
 422 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 423
 424         * Makefile.in: new targets ld.ms, ld-index.ms
 425         ld.texinfo: remove tabs, other cleanups for texi2roff
 426
 427 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 428
 429         * ldmain.c (main): Make config.magic_demand_paged be true
 430         by default.  Don't the WP_TEXT and D_PAGED flags of
 431         output_bfd here; it's too late, so set it when output_bfd
 432         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 433         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 434         * ldlang.c: Remove some duplicate extern declarations.
 435         * ldgram.y: Fixes to -N and -n options.
 436         * Makefile.in:  Recognize upper case letters in sed script
 437         to remove assignments from script files.
 438         * ldtemplate:  Don't assukme that -N or -n options
 439         imply use of -r script.
 440         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 441
 442 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 443
 444         * ldtemplate: include bfd.h before sysdep.h.
 445
 446 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 447
 448         Restructure configuration scheme for bfd, binutils, ld.
 449
 450         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 451         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 452         Change some config names to match other dirs.
 453         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 454         get defined first.
 455         * config/:  Rename some config files to match up h-*.h names.
 456         Remove all the HOST_SYS definitions from the config files.
 457
 458 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 459
 460         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 461         * ldtemplate: Remove ldfile_add_library_path calls;
 462         just use the SEARCH_DIR commands in the script files.
 463         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 464         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 465         This is primarily intended for cross-linking, where you would
 466         place libaries in a different place than native libraries.
 467         Also, emulations made from ldtemplate now use $(srcdir).
 468         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 469         form; people can use the Makefile's LIB_PATH to override.
 470
 471 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 472
 473         * Makefile.in: fix target ld.dvi, add target ld.info
 474         ld.texinfo: make info filename ld.info
 475
 476 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
 477
 478         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
 479         Make).
 480         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
 481         few BFD types & enums.
