3 Major rewrite of how ld is configured. The major idea
4 is to use shell scripts to generate everything.
5 * generic.em replaces ldtemplate.
6 * Other *.em files replace various *.c files.
7 A *.em file is a shell script that generates the corresponding
8 ld__*.c file that implements an emulation. This is usually
9 a straight 'cat' of a here-document, possibly with substitutions.
10 * Script files (*.sc) are places by *.sc-sh scripts.
11 Again, these are simple shell scripts that 'cat'
12 here-documents, usually with some substitutions.
13 The output a *.sc-sh is a script file.
14 * Each emulation is defined by a short shell script with
15 extension *.sh that specifies the emulation-specific
16 parameters (such as the name of the *.sh-sc and *.em
18 * genscript.sh is the master shell script used to generate
19 an emulation. It is passed various argument, including
20 the name a the emulation-speciic *.sh file that it
21 "sources" to set variables to emulation-specifc parameters.
22 * config/mt-foo: Changed EMUL=GLDFOO_EMULATION_NAME
23 to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
24 * config/mh-foo: Rename LDEMULATION names as appropriate
25 (usually 'gldfoo' -> plain 'foo').
26 * ldwrite.c: Fixed a typo in a comment.
27 * Makefile.in: Major changes. Removed some the sed
28 magic to converts scripts, since that is now handled
29 by genscripts.sh and the *.sc-sh scipt generators.
30 * config.h: Remove a bunch of macros defining emulations
31 and targets. This becomes one less file to edit when
32 adding emulations or targets.
33 * ldemul.h (struct ld_emulation_xfer_struct): Add
34 emulation_name and target_name fields.
35 * ldemul.c, ldemul.h: Define some default functions used
36 by most emulations (and remove from the *.em scripts).
37 * ldemul.c (ldemul_choose_target): Search the new
38 ld_emulations array using a loop (instead of a hardwired
40 Define the ld_emulation from the automatically-geenrated
41 ldemul-list.h. This means you no longer have to edit ldemul.c
42 to add a new emulation.
43 * ldmain.c: Replace {GLD,LNK}960_EMULATION_NAME by
44 their expansions, since the former no longer exist.
45 * PORTING: A very rough first draft of a porting guide.
47 * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
48 to be terminated by a new-line (instead of requiring a semicolon).
50 Mon Feb 10 16:21:02 1992 Steve Chamberlain (sac at rtl.cygnus.com)
52 * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
53 tests for NULL pointers all over the place.
54 * ldlang.c (lang_process): remember to relocate global symbols
55 *after* relaxing has done it stuff.
57 Thu Feb 6 11:40:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
59 * config/mt-coff-h8300: use EMUL like everything else
60 * ldlang.c: (print_padding_statement): print the right address.
61 * Makefile.in, config.h, ldemul.c: renamed h8300hds to h8300hms
64 Tue Feb 4 15:28:01 1992 Steve Chamberlain (sac at rtl.cygnus.com)
66 * ldlex.l: Put pack -noinhibit-exec and -sort-common
67 * ldlang.c (print_data_statement): print the right address.
69 Thu Jan 30 17:51:53 1992 Per Bothner (bothner at cygnus.com)
71 * Makefile.in: The rule for testing ld by re-linking itself
72 via an intermediate -r link was moved to the ld1 rule
73 instead of the ld2 rule. This allows ld2 and ld3 to be identical,
74 which allows the bootstrap rule to work.
75 * ldctor.c (find_constructors): Don't create a constructor
76 list if it is already defined (as would happen if ld is
79 Wed Jan 29 08:35:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
81 * config/mh-sparc.h: now uses libgcc.a
82 * ldmain.c: quit using exit
83 * *sc: use *(COMMON) rather than [COMMON]
84 * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
85 to allow preprocessing of .l file.
86 * Makefile.in: New ldlex.l mangling
87 * ldexp.c (fold_binary): perform expressions with % and / in
89 * ldfile.c (open_a): open archives on VMS in a special way
92 Tue Jan 28 10:18:16 1992 Steve Chamberlain (sac at rtl.cygnus.com)
94 * ldgram.y: map -M behave in the same way as -Map (sets file name
96 * ldsym.c, ldlang.c: remember that size of a section is dependent on
97 whether or not relaxing has been done.
98 * ldmain.c: don't open a map file if it doesn't have a name
99 * relax.c: all the brains have moved into bfd.
100 * ldwrite.c: ammend comment
102 Fri Jan 24 14:23:46 1992 Steve Chamberlain (sac at rtl.cygnus.com)
104 * Makefile.in: added relax, also made three stage go through a
107 * config.h: if GNU960 defined, then default emulation mode is

110 * ldlang.c: map to file hooks
111 * ldgram.y: added -Map -relax
112 * ldlex.l: added -relax, -Map
113 * ldmain.c: open map file
114 * ldmisc.c: support for map file
115 * ldwrite.c: new relax magic
117 Thu Dec 19 18:49:51 1991 John Gilmore (gnu at cygnus.com)
119 * Makefile.in, config/tm-*.h: Clean up make output, only
120 pass DEFAULT_EMULATION to ldmain.c.
122 Wed Dec 18 15:02:47 1991 Per Bothner (bothner at cygnus.com)
124 * ldver.c: Bump to version 1.94.
126 Tue Dec 10 04:07:23 1991 K. Richard Pixley (rich at rtl.cygnus.com)
128 * Makefile.in: infodir belongs in datadir.
130 Mon Dec 9 16:26:43 1991 Per Bothner (bothner at cygnus.com)
132 * Makefile.in: Pass -y to bison. (Again;
133 accidentally deleted by Rich.)
134 * news.sc, ldgld68k.sc: Define __end as well as _end.
136 Sat Dec 7 17:19:26 1991 Steve Chamberlain (sac at rtl.cygnus.com)
138 * ldindr.h: added to contain prototypes of ldindr.c
139 * ldfile.c: include ctype.h
140 * ldmain.c: include the requried prototype headers
141 * ldwrite.c: get_reloc_upper_bound has been renamed
142 bfd_get_reloc_upper_bound
144 Fri Dec 6 23:29:26 1991 K. Richard Pixley (rich at rtl.cygnus.com)
146 * Makefile.in: punt "fundamental" mode because it breaks my emacs
147 macros. install using INSTALL_PROGRAM and INSTALL_DATA. remove
148 spaces following hyphens, bsd make can't cope. added
149 standards.text support and made it look like all the other
152 * configure.in: configure now runs entirely in objdir so make file
153 existence checks against ${srcdir}. Mark this directory as
156 Thu Dec 5 22:46:16 1991 K. Richard Pixley (rich at rtl.cygnus.com)
158 * Makefile.in: idestdir and ddestdir go away. Added copyrights
159 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
160 and mandir now keyed off datadir by default.
162 Wed Dec 4 23:36:55 1991 Per Bothner (bothner at cygnus.com)
164 * ldver.c: Bumped version to 1.93.
165 * Makefile.in: Pass -y to bison.
167 Mon Nov 25 18:28:40 1991 Steve Chamberlain (sac at cygnus.com)
169 * config.h: h8 is now coff, not ieee
170 * h8300hds.sc: reflect the same
172 Thu Nov 14 19:55:09 1991 Per Bothner (bothner at cygnus.com)
174 * ldver.c (ldversion()): Update to 1.92.
175 * ldctor.c: There are two places constructor sets
176 can be defined. One of them checked for an existing
177 duplicate, the other didn't. Unfortunately, the latter
178 was called after the former ...
179 So, factor out code for inserting a new element into
180 constructor_name_list (after checking for a duplicate)
181 into a new function add_constructor_name, and call
182 it from both aforementioned places (ldlang_add_constructor
183 and ldlang_check_for_constructors).
185 Wed Nov 13 15:17:43 1991 Per Bothner (bothner at cygnus.com)
187 * Makefile.in: Rename .c files generated from ldtemplate
188 to have names starting with ld__. This helps 'make clean'.
190 Tue Nov 12 18:36:50 1991 Steve Chamberlain (sac at cygnus.com)
192 * Makefile.in: Take out the version number for install
193 * m88kbcs.sc: put in contructor blocks.
195 Mon Nov 11 18:47:33 1991 Per Bothner (bothner at cygnus.com)
197 * ldmisc.c, ldmisc.h: Re-write info() to take a filename
198 parameter, a format, and an arg pointer, and rename it to
199 vfinfo(). Write info() in terms of new vfinfo().
200 New einfo() is the same as info(), except it writes to stderr.
201 * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
202 ldmisc.c: Replace "error" calls to info() by new einfo().
204 Mon Nov 11 09:57:32 1991 Steve Chamberlain (steve at cygnus.com)
206 * ldlex.l ldgram.y: made -V option do same as -v
207 * Makefile.in: Added $(MINUS_G) flag so debugging can be
210 Sun Nov 3 16:37:37 1991 Steve Chamberlain (steve at cygnus.com)
211 i386 aout changes from Bob Kukura
212 * Makefile.in, config.h: added i386aout support
213 * configure.in: fixed /h-{myhost} typo
214 * ldgram.y: -MM now gives more boring map.
215 * ldlang.c: now does D_PAGED flag the right way.
216 * ldsym.c: -MM flags does the right thing.
218 Sun Nov 3 15:00:03 1991 Per Bothner (bothner at cygnus.com)
220 * configure.in: Fixed typo. Also, a fix for hp300bsd.
221 * ldlang.c (init_os): Compensate for BFD change,
222 where bfd_make_section now returns NULL for a duplicate
223 section request, instead of the old section.
225 Thu Oct 17 15:27:13 1991 Per Bothner (bothner at cygnus.com)
227 * ldver.c: Bump to version 1.91 (consistent with binutils).
229 Wed Oct 16 12:27:08 1991 Per Bothner (bothner at cygnus.com)
231 * Makefile.in, config.h, ld.h, ldemul.c, ldexp.c, ldexp.h,
232 ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
233 ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
234 ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
235 Add or update copyright notices.
237 Mon Oct 14 23:55:27 1991 Per Bothner (bothner at cygnus.com)
240 * Makefile.in: Changed installation directory name scheme
241 to be consistent with gcc. Also changed 'install'.

245 * Makefile.in: new targets ld.mm, ld.me
247 Mon Oct 14 17:27:24 1991 Per Bothner (bothner at cygnus.com)
249 * Makefile.in, ldtemplate: Need to use separate scripts
250 for -n and -N options. Yet more complication.
252 Fri Oct 11 22:40:46 1991 John Gilmore (gnu at cygnus.com)
254 * Makefile.in: Avoid using $< in explicit Make rules (it doesn't
255 work). Add some lines to avoid Sun Make VPATH bugs.
257 Fri Oct 11 16:42:22 1991 Per Bothner (bothner at cygnus.com)
259 * news.sc: Add alignment for data segment.
260 * ldtemplate: Add (yet another) script to get for -n or -N
261 options. (These need different alignment than ZMAGIC files.)
262 * Makefile.in: Add stuff for new foo.xn scripts.
263 These are generated by replacing "ALIGN(0x...00)" by ".".
265 Fri Oct 11 15:43:04 1991 Roland H. Pesch (pesch at cygnus.com)
267 * Makefile.in: new targets ld.ms, ld-index.ms
268 ld.texinfo: remove tabs, other cleanups for texi2roff
270 Fri Oct 11 13:51:54 1991 Per Bothner (bothner at cygnus.com)
272 * ldmain.c (main): Make config.magic_demand_paged be true
273 by default. Don't the WP_TEXT and D_PAGED flags of
274 output_bfd here; it's too late, so set it when output_bfd
275 is created (in ldlang.c). Also fix setting of EXEC_P flag
276 * ldlang.c (ldlang_open_output): Set output_bfd->flags here.
277 * ldlang.c: Remove some duplicate extern declarations.
278 * ldgram.y: Fixes to -N and -n options.
279 * Makefile.in: Recognize upper case letters in sed script
280 to remove assignments from script files.
281 * ldtemplate: Don't assukme that -N or -n options
282 imply use of -r script.
283 * mkscript.c: Tweaking to correctly handle \n and \\ in input.
285 Fri Oct 11 10:29:27 1991 Steve Chamberlain (steve at cygnus.com)
287 * ldtemplate: include bfd.h before sysdep.h.
289 Fri Oct 11 04:24:45 1991 John Gilmore (gnu at cygnus.com)
291 Restructure configuration scheme for bfd, binutils, ld.
293 * include/sys/h-*.h: Move to bfd/hosts/h-*.h.
294 * configure.in: Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
295 Change some config names to match other dirs.
296 * *.c: Include bfd.h before sysdep.h, so ansidecl and PROTO()
298 * config/: Rename some config files to match up h-*.h names.
299 Remove all the HOST_SYS definitions from the config files.
301 Tue Oct 8 16:00:57 1991 Per Bothner (bothner at cygnus.com)
303 * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
304 * ldtemplate: Remove ldfile_add_library_path calls;
305 just use the SEARCH_DIR commands in the script files.
306 * Makefile.in: Add LIB_PATH macro, which if set is used to replace
307 the SEARCH_DIR commands in the scripts (using ugly sed magic).
308 This is primarily intended for cross-linking, where you would
309 place libaries in a different place than native libraries.
310 Also, emulations made from ldtemplate now use $(srcdir).
311 * ldglda29k.sc: Change SEARCH_DIR commands to a conventional
312 form; people can use the Makefile's LIB_PATH to override.
314 Tue Oct 8 14:51:21 1991 Roland H. Pesch (pesch at cygnus.com)
316 * Makefile.in: fix target ld.dvi, add target ld.info
317 ld.texinfo: make info filename ld.info
319 Fri Oct 4 21:51:58 1991 John Gilmore (gnu at cygnus.com)
321 * Makefile.in: Avoid using $< in non-suffix rules (breaks on Sun
323 * ldfile.c, ldlang.c, ldmain.c, ldwrite.c: Cope with renames of a
324 few BFD types & enums.
