   3         * cplus-dem.c: yet another copy of this - maybe it should go into
   4         libiberty ?
   5         * ldgram.y: now -V and -v have different actions
   6         * ldver.c: if -V, prints list of emulations compiled in
   7         * ldmisc.c: support for cplus demangling

  10 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
  11
  12         * Makefile.in:  Change mkscript rule into one for ./mkscript
  13         (for the sake of makes that don't realize they're the same).
  14         * PORTING:  Add more details.
  15         * genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.
  16
  17 Mon Feb 17 12:04:36 1992  Per Bothner  (bothner at cygnus.com)
  18
  19         * Makefile.in, and new files hp300bsd.sh, config/mh-hp300bsd,
  20         config/mt-hp300bsd:  New port to hp300 running BSD.

  23
  24         Major rewrite of how ld is configured.  The major idea
  25         is to use shell scripts to generate everything.
  26         * generic.em replaces ldtemplate.
  27         * Other *.em files replace various *.c files.
  28         A *.em file is a shell script that generates the corresponding
  29         ld__*.c file that implements an emulation.  This is usually
  30         a straight 'cat' of a here-document, possibly with substitutions.
  31         * Script files (*.sc) are places by *.sc-sh scripts.
  32         Again, these are simple shell scripts that 'cat'
  33         here-documents, usually with some substitutions.
  34         The output a *.sc-sh is a script file.
  35         * Each emulation is defined by a short shell script with
  36         extension *.sh that specifies the emulation-specific
  37         parameters (such as the name of the *.sh-sc and *.em
  38         files to use).
  39         * genscript.sh is the master shell script used to generate
  40         an emulation.  It is passed various argument, including
  41         the name a the emulation-speciic *.sh file that it
  42         "sources" to set variables to emulation-specifc parameters.
  43         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
  44         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
  45         * config/mh-foo:  Rename LDEMULATION names as appropriate
  46         (usually 'gldfoo' -> plain 'foo').
  47         * ldwrite.c:  Fixed a typo in a comment.
  48         * Makefile.in:  Major changes.  Removed some the sed
  49         magic to converts scripts, since that is now handled
  50         by genscripts.sh and the *.sc-sh scipt generators.
  51         * config.h:  Remove a bunch of macros defining emulations
  52         and targets.  This becomes one less file to edit when
  53         adding emulations or targets.
  54         * ldemul.h (struct ld_emulation_xfer_struct):  Add
  55         emulation_name and target_name fields.
  56         * ldemul.c, ldemul.h:  Define some default functions used
  57         by most emulations (and remove from the *.em scripts).
  58         * ldemul.c (ldemul_choose_target):  Search the new
  59         ld_emulations array using a loop (instead of a hardwired
  60         nested if statement).
  61         Define the ld_emulation from the automatically-geenrated
  62         ldemul-list.h.  This means you no longer have to edit ldemul.c
  63         to add a new emulation.
  64         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
  65         their expansions, since the former no longer exist.
  66         * PORTING:  A very rough first draft of a porting guide.
  67
  68         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
  69         to be terminated by a new-line (instead of requiring a semicolon).
  70
  71 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
  72
  73         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
  74         tests for NULL pointers all over the place.
  75         * ldlang.c (lang_process): remember to relocate global symbols
  76         *after* relaxing has done it stuff.
  77
  78 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
  79
  80         * config/mt-coff-h8300: use EMUL like everything else
  81         * ldlang.c: (print_padding_statement): print the right address.
  82         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms
  83
  84
  85 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
  86
  87         * ldlex.l: Put pack -noinhibit-exec and -sort-common
  88         * ldlang.c (print_data_statement): print the right address.
  89
  90 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
  91
  92         * Makefile.in:  The rule for testing ld by re-linking itself
  93         via an intermediate -r link was moved to the ld1 rule
  94         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
  95         which allows the bootstrap rule to work.
  96         * ldctor.c (find_constructors):  Don't create a constructor
  97         list if it is already defined (as would happen if ld is
  98         invoked by collect).
  99
 100 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 101
 102         * config/mh-sparc.h: now uses libgcc.a
 103         * ldmain.c: quit using exit
 104         * *sc: use *(COMMON) rather than [COMMON]
 105         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 106         to allow preprocessing of .l file.
 107         * Makefile.in: New ldlex.l mangling
 108         * ldexp.c (fold_binary): perform expressions with % and / in
 109         integer.
 110         * ldfile.c (open_a): open archives on VMS in a special way
 111
 112
 113 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 114
 115         * ldgram.y: map -M behave in the same way as -Map (sets file name
 116         to be "-".
 117         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 118         whether or not relaxing has been done.
 119         * ldmain.c: don't open a map file if it doesn't have a name
 120         * relax.c: all the brains have moved into bfd.
 121         * ldwrite.c: ammend comment
 122
 123 Fri Jan 24 14:23:46 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 124

 126         partial link stage.
 127         * relax.c : added
 128         * config.h: if GNU960 defined, then default emulation mode is
 129         GLD960
 130         * ldexp.h, ldexp.c: map to file hooks
 131         * ldlang.c: map to file hooks
 132         * ldgram.y: added -Map -relax
 133         * ldlex.l: added -relax, -Map
 134         * ldmain.c: open map file
 135         * ldmisc.c: support for map file
 136         * ldwrite.c: new relax magic
 137
 138 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)
 139
 140         * Makefile.in, config/tm-*.h:  Clean up make output, only
 141         pass DEFAULT_EMULATION to ldmain.c.
 142
 143 Wed Dec 18 15:02:47 1991  Per Bothner  (bothner at cygnus.com)
 144
 145         * ldver.c:  Bump to version 1.94.
 146
 147 Tue Dec 10 04:07:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 148
 149         * Makefile.in: infodir belongs in datadir.
 150
 151 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
 152
 153         * Makefile.in:  Pass -y to bison.  (Again;
 154         accidentally deleted by Rich.)
 155         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 156
 157 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 158
 159         * ldindr.h: added to contain prototypes of ldindr.c
 160         * ldfile.c: include ctype.h
 161         * ldmain.c: include the requried prototype headers
 162         * ldwrite.c: get_reloc_upper_bound has been renamed
 163         bfd_get_reloc_upper_bound
 164
 165 Fri Dec  6 23:29:26 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 166
 167         * Makefile.in: punt "fundamental" mode because it breaks my emacs
 168           macros.  install using INSTALL_PROGRAM and INSTALL_DATA.  remove
 169           spaces following hyphens, bsd make can't cope.  added
 170           standards.text support and made it look like all the other
 171           makefiles.
 172
 173         * configure.in: configure now runs entirely in objdir so make file
 174           existence checks against ${srcdir}.  Mark this directory as
 175           target dependent.
 176
 177 Thu Dec  5 22:46:16 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 178
 179         * Makefile.in: idestdir and ddestdir go away.  Added copyrights
 180           and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
 181           and mandir now keyed off datadir by default.
 182
 183 Wed Dec  4 23:36:55 1991  Per Bothner  (bothner at cygnus.com)
 184
 185         * ldver.c:  Bumped version to 1.93.
 186         * Makefile.in:  Pass -y to bison.
 187
 188 Mon Nov 25 18:28:40 1991  Steve Chamberlain  (sac at cygnus.com)
 189
 190         * config.h: h8 is now coff, not ieee
 191         * h8300hds.sc: reflect the same
 192
 193 Thu Nov 14 19:55:09 1991  Per Bothner  (bothner at cygnus.com)
 194
 195         * ldver.c (ldversion()):  Update to 1.92.
 196         * ldctor.c: There are two places constructor sets
 197         can be defined.  One of them checked for an existing
 198         duplicate, the other didn't.  Unfortunately, the latter
 199         was called after the former ...
 200         So, factor out code for inserting a new element into
 201         constructor_name_list (after checking for a duplicate)
 202         into a new function add_constructor_name, and call
 203         it from both aforementioned places (ldlang_add_constructor
 204         and ldlang_check_for_constructors).
 205
 206 Wed Nov 13 15:17:43 1991  Per Bothner  (bothner at cygnus.com)
 207
 208         * Makefile.in:  Rename .c files generated from ldtemplate
 209         to have names starting with ld__.  This helps 'make clean'.
 210
 211 Tue Nov 12 18:36:50 1991  Steve Chamberlain  (sac at cygnus.com)
 212
 213         * Makefile.in: Take out the version number for install
 214         * m88kbcs.sc: put in contructor blocks.
 215
 216 Mon Nov 11 18:47:33 1991  Per Bothner  (bothner at cygnus.com)
 217
 218         * ldmisc.c, ldmisc.h:  Re-write info() to take a filename
 219         parameter, a format, and an arg pointer, and rename it to
 220         vfinfo().  Write info() in terms of new vfinfo().
 221         New einfo() is the same as info(), except it writes to stderr.
 222         * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
 223         ldmisc.c:  Replace "error" calls to info() by new einfo().
 224
 225 Mon Nov 11 09:57:32 1991  Steve Chamberlain  (steve at cygnus.com)
 226
 227         * ldlex.l ldgram.y: made -V option do same as -v
 228         * Makefile.in: Added $(MINUS_G) flag so debugging can be
 229         turned off
 230
 231 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
 232          i386 aout changes from Bob Kukura
 233         * Makefile.in, config.h: added i386aout support
 234         * configure.in: fixed /h-{myhost} typo
 235         * ldgram.y: -MM now gives more boring map.
 236         * ldlang.c: now does D_PAGED flag the right way.
 237         * ldsym.c: -MM flags does the right thing.
 238
 239 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
 240
 241         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 242         * ldlang.c (init_os):  Compensate for BFD change,
 243         where bfd_make_section now returns NULL for a duplicate
 244         section request, instead of the old section.
 245
 246 Thu Oct 17 15:27:13 1991  Per Bothner  (bothner at cygnus.com)
 247
 248         * ldver.c: Bump to version 1.91 (consistent with binutils).
 249
 250 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)
 251
 252         * Makefile.in, config.h, ld.h, ldemul.c, ldexp.c, ldexp.h,
 253         ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
 254         ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
 255         ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
 256         Add or update copyright notices.
 257
 258 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 259
 260         * README: New file.
 261         * Makefile.in:  Changed installation directory name scheme
 262         to be consistent with gcc.  Also changed 'install'.
 263
 264 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 265
 266         * Makefile.in: new targets ld.mm, ld.me
 267
 268 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 269
 270         * Makefile.in, ldtemplate:  Need to use separate scripts
 271         for -n and -N options.  Yet more complication.
 272
 273 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 274
 275         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 276         work).  Add some lines to avoid Sun Make VPATH bugs.
 277
 278 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 279
 280         * news.sc: Add alignment for data segment.
 281         * ldtemplate: Add (yet another) script to get for -n or -N
 282         options.  (These need different alignment than ZMAGIC files.)
 283         * Makefile.in:  Add stuff for new foo.xn scripts.
 284         These are generated by replacing "ALIGN(0x...00)" by ".".
 285
 286 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 287
 288         * Makefile.in: new targets ld.ms, ld-index.ms
 289         ld.texinfo: remove tabs, other cleanups for texi2roff
 290
 291 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 292
 293         * ldmain.c (main): Make config.magic_demand_paged be true
 294         by default.  Don't the WP_TEXT and D_PAGED flags of
 295         output_bfd here; it's too late, so set it when output_bfd
 296         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 297         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 298         * ldlang.c: Remove some duplicate extern declarations.
 299         * ldgram.y: Fixes to -N and -n options.
 300         * Makefile.in:  Recognize upper case letters in sed script
 301         to remove assignments from script files.
 302         * ldtemplate:  Don't assukme that -N or -n options
 303         imply use of -r script.
 304         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 305
 306 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 307
 308         * ldtemplate: include bfd.h before sysdep.h.
 309
 310 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 311
 312         Restructure configuration scheme for bfd, binutils, ld.
 313
 314         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 315         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 316         Change some config names to match other dirs.
 317         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 318         get defined first.
 319         * config/:  Rename some config files to match up h-*.h names.
 320         Remove all the HOST_SYS definitions from the config files.
 321
 322 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 323
 324         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 325         * ldtemplate: Remove ldfile_add_library_path calls;
 326         just use the SEARCH_DIR commands in the script files.
 327         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 328         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 329         This is primarily intended for cross-linking, where you would
 330         place libaries in a different place than native libraries.
 331         Also, emulations made from ldtemplate now use $(srcdir).
 332         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 333         form; people can use the Makefile's LIB_PATH to override.
 334
 335 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 336
 337         * Makefile.in: fix target ld.dvi, add target ld.info
