 771
 772         * Makefile.in:  Use srcdir instead of VPATH in ldgram/ldlex
 773         rules, since these are used when building a distribution.

 968 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 969
 970         Major rewrite of how ld is configured.  The major idea
 971         is to use shell scripts to generate everything.
 972         * generic.em replaces ldtemplate.
 973         * Other *.em files replace various *.c files.
 974         A *.em file is a shell script that generates the corresponding
 975         ld__*.c file that implements an emulation.  This is usually
 976         a straight 'cat' of a here-document, possibly with substitutions.
 977         * Script files (*.sc) are places by *.sc-sh scripts.
 978         Again, these are simple shell scripts that 'cat'
 979         here-documents, usually with some substitutions.
 980         The output a *.sc-sh is a script file.
 981         * Each emulation is defined by a short shell script with
 982         extension *.sh that specifies the emulation-specific
 983         parameters (such as the name of the *.sh-sc and *.em
 984         files to use).
 985         * genscript.sh is the master shell script used to generate
 986         an emulation.  It is passed various argument, including
 987         the name a the emulation-speciic *.sh file that it
 988         "sources" to set variables to emulation-specifc parameters.
 989         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 990         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 991         * config/mh-foo:  Rename LDEMULATION names as appropriate
 992         (usually 'gldfoo' -> plain 'foo').
 993         * ldwrite.c:  Fixed a typo in a comment.
 994         * Makefile.in:  Major changes.  Removed some the sed
 995         magic to converts scripts, since that is now handled
 996         by genscripts.sh and the *.sc-sh scipt generators.
 997         * config.h:  Remove a bunch of macros defining emulations
 998         and targets.  This becomes one less file to edit when
 999         adding emulations or targets.
1000         * ldemul.h (struct ld_emulation_xfer_struct):  Add
1001         emulation_name and target_name fields.
1002         * ldemul.c, ldemul.h:  Define some default functions used
1003         by most emulations (and remove from the *.em scripts).
1004         * ldemul.c (ldemul_choose_target):  Search the new
1005         ld_emulations array using a loop (instead of a hardwired
1006         nested if statement).
1007         Define the ld_emulation from the automatically-geenrated
1008         ldemul-list.h.  This means you no longer have to edit ldemul.c
1009         to add a new emulation.
1010         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
1011         their expansions, since the former no longer exist.
1012         * PORTING:  A very rough first draft of a porting guide.
1013
1014         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
1015         to be terminated by a new-line (instead of requiring a semicolon).
1016
1017 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1018
1019         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
1020         tests for NULL pointers all over the place.
1021         * ldlang.c (lang_process): remember to relocate global symbols
1022         *after* relaxing has done it stuff.
1023
1024 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1025
1026         * config/mt-coff-h8300: use EMUL like everything else
1027         * ldlang.c: (print_padding_statement): print the right address.
1028         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms

1031 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1032
1033         * ldlex.l: Put pack -noinhibit-exec and -sort-common
1034         * ldlang.c (print_data_statement): print the right address.
1035
1036 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
1037
1038         * Makefile.in:  The rule for testing ld by re-linking itself
1039         via an intermediate -r link was moved to the ld1 rule
1040         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
1041         which allows the bootstrap rule to work.
1042         * ldctor.c (find_constructors):  Don't create a constructor
1043         list if it is already defined (as would happen if ld is

1047
1048         * config/mh-sparc.h: now uses libgcc.a
1049         * ldmain.c: quit using exit
1050         * *sc: use *(COMMON) rather than [COMMON]
1051         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
1052         to allow preprocessing of .l file.
1053         * Makefile.in: New ldlex.l mangling
1054         * ldexp.c (fold_binary): perform expressions with % and / in
1055         integer.
1056         * ldfile.c (open_a): open archives on VMS in a special way

1059 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
1060
1061         * ldgram.y: map -M behave in the same way as -Map (sets file name
1062         to be "-".
1063         * ldsym.c, ldlang.c: remember that size of a section is dependent on
1064         whether or not relaxing has been done.
1065         * ldmain.c: don't open a map file if it doesn't have a name
1066         * relax.c: all the brains have moved into bfd.

1072         partial link stage.
1073         * relax.c : added
1074         * config.h: if GNU960 defined, then default emulation mode is
1075         GLD960
1076         * ldexp.h, ldexp.c: map to file hooks
1077         * ldlang.c: map to file hooks

1090
1091         * ldver.c:  Bump to version 1.94.
1092
1093 Tue Dec 10 04:07:23 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
1094
1095         * Makefile.in: infodir belongs in datadir.
1096
1097 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
1098
1099         * Makefile.in:  Pass -y to bison.  (Again;
1100         accidentally deleted by Rich.)
1101         * news.sc, ldgld68k.sc:  Define __end as well as _end.
1102
1103 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
1104
1105         * ldindr.h: added to contain prototypes of ldindr.c
1106         * ldfile.c: include ctype.h
1107         * ldmain.c: include the requried prototype headers
1108         * ldwrite.c: get_reloc_upper_bound has been renamed
1109         bfd_get_reloc_upper_bound
1110
1111 Fri Dec  6 23:29:26 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
1112
1113         * Makefile.in: punt "fundamental" mode because it breaks my emacs
1114           macros.  install using INSTALL_PROGRAM and INSTALL_DATA.  remove
1115           spaces following hyphens, bsd make can't cope.  added
1116           standards.text support and made it look like all the other
1117           makefiles.
1118
1119         * configure.in: configure now runs entirely in objdir so make file
1120           existence checks against ${srcdir}.  Mark this directory as
1121           target dependent.
1122
1123 Thu Dec  5 22:46:16 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
1124
1125         * Makefile.in: idestdir and ddestdir go away.  Added copyrights
1126           and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
1127           and mandir now keyed off datadir by default.
1128
1129 Wed Dec  4 23:36:55 1991  Per Bothner  (bothner at cygnus.com)
1130

1134 Mon Nov 25 18:28:40 1991  Steve Chamberlain  (sac at cygnus.com)
1135

1137         * h8300hds.sc: reflect the same
1138
1139 Thu Nov 14 19:55:09 1991  Per Bothner  (bothner at cygnus.com)
1140
1141         * ldver.c (ldversion()):  Update to 1.92.
1142         * ldctor.c: There are two places constructor sets
1143         can be defined.  One of them checked for an existing
1144         duplicate, the other didn't.  Unfortunately, the latter
1145         was called after the former ...
1146         So, factor out code for inserting a new element into
1147         constructor_name_list (after checking for a duplicate)
1148         into a new function add_constructor_name, and call
1149         it from both aforementioned places (ldlang_add_constructor
1150         and ldlang_check_for_constructors).
1151
1152 Wed Nov 13 15:17:43 1991  Per Bothner  (bothner at cygnus.com)
1153
1154         * Makefile.in:  Rename .c files generated from ldtemplate
1155         to have names starting with ld__.  This helps 'make clean'.
1156
1157 Tue Nov 12 18:36:50 1991  Steve Chamberlain  (sac at cygnus.com)
1158
1159         * Makefile.in: Take out the version number for install
1160         * m88kbcs.sc: put in contructor blocks.
1161
1162 Mon Nov 11 18:47:33 1991  Per Bothner  (bothner at cygnus.com)
1163
1164         * ldmisc.c, ldmisc.h:  Re-write info() to take a filename
1165         parameter, a format, and an arg pointer, and rename it to
1166         vfinfo().  Write info() in terms of new vfinfo().
1167         New einfo() is the same as info(), except it writes to stderr.
1168         * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
1169         ldmisc.c:  Replace "error" calls to info() by new einfo().

1172
1173         * ldlex.l ldgram.y: made -V option do same as -v
1174         * Makefile.in: Added $(MINUS_G) flag so debugging can be
1175         turned off
1176
1177 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
1178          i386 aout changes from Bob Kukura
1179         * Makefile.in, config.h: added i386aout support
1180         * configure.in: fixed /h-{myhost} typo
1181         * ldgram.y: -MM now gives more boring map.
1182         * ldlang.c: now does D_PAGED flag the right way.
1183         * ldsym.c: -MM flags does the right thing.
1184
1185 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
1186
1187         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
1188         * ldlang.c (init_os):  Compensate for BFD change,
1189         where bfd_make_section now returns NULL for a duplicate
1190         section request, instead of the old section.
1191
1192 Thu Oct 17 15:27:13 1991  Per Bothner  (bothner at cygnus.com)
1193
1194         * ldver.c: Bump to version 1.91 (consistent with binutils).
1195
1196 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)
1197

1204 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
1205
1206         * README: New file.
1207         * Makefile.in:  Changed installation directory name scheme
1208         to be consistent with gcc.  Also changed 'install'.
1209

1211
1212         * Makefile.in: new targets ld.mm, ld.me
1213
1214 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
1215
1216         * Makefile.in, ldtemplate:  Need to use separate scripts
1217         for -n and -N options.  Yet more complication.
1218
1219 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
1220
1221         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
1222         work).  Add some lines to avoid Sun Make VPATH bugs.
1223
1224 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
1225
1226         * news.sc: Add alignment for data segment.
1227         * ldtemplate: Add (yet another) script to get for -n or -N
1228         options.  (These need different alignment than ZMAGIC files.)
1229         * Makefile.in:  Add stuff for new foo.xn scripts.
1230         These are generated by replacing "ALIGN(0x...00)" by ".".
1231
1232 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
1233
1234         * Makefile.in: new targets ld.ms, ld-index.ms
1235         ld.texinfo: remove tabs, other cleanups for texi2roff
1236
1237 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
1238
1239         * ldmain.c (main): Make config.magic_demand_paged be true
1240         by default.  Don't the WP_TEXT and D_PAGED flags of
1241         output_bfd here; it's too late, so set it when output_bfd
1242         is created (in ldlang.c).  Also fix setting of EXEC_P flag
1243         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
1244         * ldlang.c: Remove some duplicate extern declarations.
1245         * ldgram.y: Fixes to -N and -n options.
1246         * Makefile.in:  Recognize upper case letters in sed script
1247         to remove assignments from script files.
1248         * ldtemplate:  Don't assukme that -N or -n options
1249         imply use of -r script.
1250         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
1251
1252 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
1253
1254         * ldtemplate: include bfd.h before sysdep.h.
1255
1256 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
1257
1258         Restructure configuration scheme for bfd, binutils, ld.
1259
1260         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
1261         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
1262         Change some config names to match other dirs.
1263         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
1264         get defined first.
1265         * config/:  Rename some config files to match up h-*.h names.
1266         Remove all the HOST_SYS definitions from the config files.
1267
1268 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
1269
1270         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
1271         * ldtemplate: Remove ldfile_add_library_path calls;
1272         just use the SEARCH_DIR commands in the script files.
1273         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
1274         the SEARCH_DIR commands in the scripts (using ugly sed magic).
1275         This is primarily intended for cross-linking, where you would
1276         place libaries in a different place than native libraries.
1277         Also, emulations made from ldtemplate now use $(srcdir).
1278         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
1279         form; people can use the Makefile's LIB_PATH to override.
1280
1281 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
1282
1283         * Makefile.in: fix target ld.dvi, add target ld.info
1284         ld.texinfo: make info filename ld.info
1285
1286 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
1287
1288         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
1289         Make).
1290         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
1291         few BFD types & enums.
1292
