  64
  65         * Makefile.in (install): Install second copy in $(tooldir)/bin

 135
 136 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
 137
 138         * Makefile.in:  Change mkscript rule into one for ./mkscript
 139         (for the sake of makes that don't realize they're the same).

 141         * genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.
 142
 143 Mon Feb 17 12:04:36 1992  Per Bothner  (bothner at cygnus.com)
 144
 145         * Makefile.in, and new files hp300bsd.sh, config/mh-hp300bsd,

 148 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 149
 150         Major rewrite of how ld is configured.  The major idea
 151         is to use shell scripts to generate everything.
 152         * generic.em replaces ldtemplate.
 153         * Other *.em files replace various *.c files.
 154         A *.em file is a shell script that generates the corresponding
 155         ld__*.c file that implements an emulation.  This is usually
 156         a straight 'cat' of a here-document, possibly with substitutions.
 157         * Script files (*.sc) are places by *.sc-sh scripts.
 158         Again, these are simple shell scripts that 'cat'
 159         here-documents, usually with some substitutions.
 160         The output a *.sc-sh is a script file.
 161         * Each emulation is defined by a short shell script with
 162         extension *.sh that specifies the emulation-specific
 163         parameters (such as the name of the *.sh-sc and *.em
 164         files to use).
 165         * genscript.sh is the master shell script used to generate
 166         an emulation.  It is passed various argument, including
 167         the name a the emulation-speciic *.sh file that it
 168         "sources" to set variables to emulation-specifc parameters.
 169         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 170         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 171         * config/mh-foo:  Rename LDEMULATION names as appropriate
 172         (usually 'gldfoo' -> plain 'foo').
 173         * ldwrite.c:  Fixed a typo in a comment.
 174         * Makefile.in:  Major changes.  Removed some the sed
 175         magic to converts scripts, since that is now handled
 176         by genscripts.sh and the *.sc-sh scipt generators.
 177         * config.h:  Remove a bunch of macros defining emulations
 178         and targets.  This becomes one less file to edit when
 179         adding emulations or targets.
 180         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 181         emulation_name and target_name fields.
 182         * ldemul.c, ldemul.h:  Define some default functions used
 183         by most emulations (and remove from the *.em scripts).
 184         * ldemul.c (ldemul_choose_target):  Search the new
 185         ld_emulations array using a loop (instead of a hardwired
 186         nested if statement).
 187         Define the ld_emulation from the automatically-geenrated
 188         ldemul-list.h.  This means you no longer have to edit ldemul.c
 189         to add a new emulation.
 190         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 191         their expansions, since the former no longer exist.
 192         * PORTING:  A very rough first draft of a porting guide.
 193
 194         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 195         to be terminated by a new-line (instead of requiring a semicolon).
 196
 197 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 198
 199         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 200         tests for NULL pointers all over the place.
 201         * ldlang.c (lang_process): remember to relocate global symbols
 202         *after* relaxing has done it stuff.
 203
 204 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 205
 206         * config/mt-coff-h8300: use EMUL like everything else
 207         * ldlang.c: (print_padding_statement): print the right address.
 208         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms
 209
 210
 211 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 212
 213         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 214         * ldlang.c (print_data_statement): print the right address.
 215
 216 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 217
 218         * Makefile.in:  The rule for testing ld by re-linking itself
 219         via an intermediate -r link was moved to the ld1 rule
 220         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 221         which allows the bootstrap rule to work.
 222         * ldctor.c (find_constructors):  Don't create a constructor
 223         list if it is already defined (as would happen if ld is
 224         invoked by collect).
 225
 226 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 227
 228         * config/mh-sparc.h: now uses libgcc.a
 229         * ldmain.c: quit using exit
 230         * *sc: use *(COMMON) rather than [COMMON]
 231         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 232         to allow preprocessing of .l file.
 233         * Makefile.in: New ldlex.l mangling
 234         * ldexp.c (fold_binary): perform expressions with % and / in
 235         integer.
 236         * ldfile.c (open_a): open archives on VMS in a special way
 237
 238
 239 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 240
 241         * ldgram.y: map -M behave in the same way as -Map (sets file name
 242         to be "-".
 243         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 244         whether or not relaxing has been done.
 245         * ldmain.c: don't open a map file if it doesn't have a name
 246         * relax.c: all the brains have moved into bfd.
 247         * ldwrite.c: ammend comment
 248
 249 Fri Jan 24 14:23:46 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 250
 251         * Makefile.in: added relax, also made three stage go through a
 252         partial link stage.
 253         * relax.c : added
 254         * config.h: if GNU960 defined, then default emulation mode is
 255         GLD960
 256         * ldexp.h, ldexp.c: map to file hooks
 257         * ldlang.c: map to file hooks
 258         * ldgram.y: added -Map -relax
 259         * ldlex.l: added -relax, -Map
 260         * ldmain.c: open map file
 261         * ldmisc.c: support for map file
 262         * ldwrite.c: new relax magic
 263
 264 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)
 265
 266         * Makefile.in, config/tm-*.h:  Clean up make output, only
 267         pass DEFAULT_EMULATION to ldmain.c.
 268
 269 Wed Dec 18 15:02:47 1991  Per Bothner  (bothner at cygnus.com)
 270
 271         * ldver.c:  Bump to version 1.94.
 272
 273 Tue Dec 10 04:07:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 274
 275         * Makefile.in: infodir belongs in datadir.
 276
 277 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
 278
 279         * Makefile.in:  Pass -y to bison.  (Again;
 280         accidentally deleted by Rich.)
 281         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 282
 283 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 284
 285         * ldindr.h: added to contain prototypes of ldindr.c
 286         * ldfile.c: include ctype.h
 287         * ldmain.c: include the requried prototype headers

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

 357 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
 358          i386 aout changes from Bob Kukura
 359         * Makefile.in, config.h: added i386aout support
 360         * configure.in: fixed /h-{myhost} typo
 361         * ldgram.y: -MM now gives more boring map.
 362         * ldlang.c: now does D_PAGED flag the right way.
 363         * ldsym.c: -MM flags does the right thing.
 364
 365 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
 366
 367         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 368         * ldlang.c (init_os):  Compensate for BFD change,
 369         where bfd_make_section now returns NULL for a duplicate
 370         section request, instead of the old section.

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