3 *../include/i386coff.h : fixed typo in type field with size
5 * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
6 support in the jump table for the swapping routines exported to
7 gdb. Now gdb works with the 386.
9 Tue May 28 17:21:43 1991 John Gilmore (gnu at cygint.cygnus.com)
11 * Merge in changes from gdb-3.95 release.
12 Makefile.in: Allow hmake and tmake files to add OFILES.
14 bfd.c: support specific targets as well as searching. When
15 searching, take default target in preference to others.
17 ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
18 liba.out.h: Don't hard-code file offsets; use N_ macros for them.
19 libbfd.h: Support specific targets as well as searching.
20 opncls.c: Support specific targets as well as searching.
21 targets.c: Search is short-circuited if default target matches.
22 liboasys.c, libieee.c: Undo bothner changes that make macros
23 work to the left of assignment, but which depend on the
24 representations of different pointer types being the same.
26 Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
28 * i386coff.c: created.
29 * coffcode.h: added support for 386.
30 * Makefile.in: added support for 386.
31 * ../include/i386coff.h: created
33 Wed May 22 07:26:38 1991 Steve Chamberlain (steve at cygint.cygnus.com)
35 * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
39 Tue May 21 08:58:58 1991 Steve Chamberlain (steve at cygint.cygnus.com)
41 * opncls.c: Changed obstack_chunk_alloc use xmalloc
43 Mon May 20 17:12:17 1991 Steve Chamberlain (steve at cygint.cygnus.com)
45 * everything: Removed sysdep.h from bfd.h and put back into files
46 from which it was split out. Now 64 bit version is built with a
47 -DHOST_64_BIT="long long" on the compile line.
50 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
52 Changed all the [get|put][name] routines to use [get|put]_[size
55 Put in support for 64 bit work. Now two versions of bfd may be
56 generated, according to the state of TARGET_64_BIT, one which is
57 32 bit only, and one which is 64/32 bits.
58 Created new back end 'demo64' to test 64 bit functionality.
60 Renamed some files to work on DOS.
62 * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
63 64bit transfer * icoff.c: added 64bit transfer * ieee.c: name
64 chage, 64 bit transfer. * liba.out.h: Split out common code from
65 sunos and newsos into liba.out. Name changes and prototype mods. *
66 libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
67 prototypes for new functions. * libcoff.h: lint * libieee.h: make
68 work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name

72 Added demo * aout32, aout64.c include aoutx.h * bout.c: used to
73 be called b.out.c * coffcode.h: used to be called coff-code.h, now
74 64bit ized. * demo64.c: 64 bit a.out back end
80 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
82 * libieee.h: Make ieee_data and ieee_ar_data macros usable
83 on LHS of assignment, even when using old compilers.
84 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
85 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
86 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
87 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
88 * targets.c: Add declaration of newsos3_vec.
91 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
93 * aout.c: fixxed some of the problems with filepos calculation.
94 (swap_ext_reloc): fixed problem with creation of relocs.
95 (aout_set_section_contents): fixed filepos problem
97 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
98 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
99 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
100 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
101 cleaned up. (coff_write_object_contents) cleaned up.
103 * ecoff.c: Totally different. Now supports ecoff fully.
105 * icoff.c: fixed problems in relocation callout.
107 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
109 * m68kcoff.c: updated target vector.
111 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
112 choose_reloc_size. (sunos4_write_object_contents) now calls
113 choose_reloc_size so outputs relocs correctly, also calculates the
114 size of the sections correctly.
118 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
120 Merge Per Bothner's changes to modularize BFD a.out a bit.
122 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
123 * ieee.c: Cast enums to int before comparing them, for brain-
125 * coff-code.h: Remove coff_get_section_contents, and use the
128 * aout.c: Derive new module from sunos.c, containing generic
129 support code for all kinds of a.out files.
131 * sunos.c: Remove all code that goes in aout.c. Split out
132 machine dependent followup in sunos4_object_p into
133 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
134 and redefine only the names we CHANGE, not all the names. Drop
135 the little-endian vector, and rename the vector as sunos4 rather
138 * b.out.c: Use aout.c routines for most of the work. Slight
139 changes for the new regime. Remove close_and_cleanup and
140 get_section_contents in favor of generics. New transfer vector
143 * newsos.c: New support for Sony NEWS, another a.out format.
145 * ecoff.c: Remove close_and_cleanup. New tvec regime.
146 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
147 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
149 * opncls.c (bfd_close): Call format-dependent write_contents
150 routine, if writing, before calling target-dependent
151 close_and_cleanup routine (which is now always generic, I think).
152 * srec.c: Use bfd_alloc instead of malloc. Remove
153 close_and_cleanup and move code from it to
154 srec_write_object_contents. Add write_contents to tvec.
155 * targets.c: Remove a.out little vector, replace a.out big
156 vector with SunOS vector. FIXME: Need Vax support again now.
158 * libbfd.h: Add write_contents format-dependent-vector to the
159 bfd_target vector. Supply a generic close_and_cleanup routine.
160 * liba.out.h: Handle the new aout.c split. Add prototypes for
161 all routines defined in aout.c. Rename "sunos" things to "aout"
162 things. Add a few fields where needed for various formats.
163 * Makefile.in: Add aout.c and newsos.c.
165 * archive.c, ieee.c, oasys.c: Lint.
167 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
170 changed forward declaration struct stat; to reduce warnings. Changed
171 comment on bfd_h_<x>_x.
173 * ../include/m68kcoff.h, ../include/intel-coff.h,
174 ../include/m88k-bcs.h
175 Now there are two incarnations of relocs, linenos and syments. One for
176 internal digestion, and one full of char arrays for I/O. The original
177 names have gone to detect errors.
179 * Makefile.in, m68kcoff.c, targets.c
180 Test new structure code with a 68k coff implementaion
182 * coff-code.h, icoff.c, coffswap.c, libcoff.h
183 Fixed all the places where there were problems with the size and
184 alignments of structures on disk and structures in memory. #ifed out
185 all the code in coffswap.c, since it should be done using the target
188 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
190 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
191 multiple reloc command.
193 * sunos.c (sunos4_set_section_contents): Made it so that sections
194 are always padded to their alignment size.
196 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
198 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
199 Clean up types and such (saber C problems).
200 * ecoff.c: Clean up types and such. Remove routines that are
201 not used. Fix up reading and swapping of shorts from files.
203 Notes on bfd-0.5.2-patch1a, from Per Bothner:
205 * a.out.vax.c: Remove two bogus "static" from prototypes.
207 * ecoff.c: Got rid of lots of non-working junk (that had
208 been copied directly from coff-code.h).
209 Updated to be consistent with updates to icoff.c and coff-code.h.
211 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
212 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
214 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
215 but until the target_vector is automatically generated,
216 it's as good as any. Note that the text offset is the only
217 difference between NewsOS and SunOs (including magic numbers).
218 (Most of the sunos_* routines should to renamed bsd_*
219 and move to a bsd.c file. Then (and when the target_vector
220 is automatically generated) it might make sense to create
221 a separate Sony target.)
223 * sysdep.h: Don't declare fread and fwrite. Causes trouble
224 on some systems, and doesn't help on others.
225 Similarly, only define X_OK if not already defined.
227 * trad-core.c: Don't include sys/stat.h - at least
228 on NewsOS 3, it has already been included.
230 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
232 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
233 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
234 symbol tables if necessary when reading them in, so gdb can use
235 them. Add "bfd_coff_" to the names so they won't conflict with
236 names in calling programs. FIXME-soon: if coff-code.h is
237 included in two BFD modules, this will cause duplicate
238 definitions; the routines should be exported to a separate,
239 common, module (probably along with a mess of other ones).
241 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
243 Improve modtime support.
245 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
246 Remove #define for bfd_get_mtime. Remove gratuitous comment.
247 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
248 BUG: archive members still do not get correct mod times.
250 Improve floating point support for core files.
252 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
253 (sunos4_core_file_p): Create a second registers section in the
254 core file, called ".reg2", for the float registers.
256 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
258 * many changes to improve archive handling; found a logic flaw in
259 bfd_check_format which only just happened to work by cooncidence.
261 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
263 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
266 * bfd.h: changed type of udata in asymbol to void *, like it
267 should be. Added bfd_reloc_dangerous enum member.
269 * coff-code.h: Fixed it so that internally generated symbols get
270 their values relocated correctly in all cases. Removed calls to
273 * icoff.c: Not understanding the destination symbol of a reloc is
274 not a failure any more, just 'dangerous'. This allows linking of
275 b.out and coff images.
277 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
281 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
283 * sunos.c (translate_to_native_sym_flags): fixed
284 sym_pointer->n_value so that symbols on the way out get their
285 section relative values calculated correctly.
287 * coff-code.h (mangle_symbols): fixed problem where tags were not
288 being relocated for structs, enums, unions. Also various lints.
290 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
292 * archive.c (get_elt_at_filepos): system_call_error returned
295 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
297 * Resolve the use of no_error and system_call_error.
298 The bfd library itself now will never set bfd_error to
301 The code still needs to be combed to make sure all the error
302 codes are correct. I suspect they are not always set correctly.
304 * The names of all the messages have _ prepended because the sun
305 bundled compiler can't distinguish from a macro which takes an
306 argument and the same identifier in a non-macro context.
308 * The reason for the above being that entry points which used to
309 be trampoline functions are now just macros which expand to a
310 direct call through the bfd's xfer vector.
312 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
313 must gas have its own version of everything (the gas version
314 had the correct value)
316 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
318 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
319 properly support i960 architecture and output correct reloc stuff.
321 * bfd.h: added prototype for bfd_printable_arch_mach, added
324 * coff-code.h: Applied patches from chrisb to support i960
325 architecture, zero relocs and swap them correcly and conditionally
326 compiled the timestamp.
328 * sunos.c: Made the default section alignment 2^3 so that doubles
329 are done properly. Fixed the same reloc bug that was in b.out.c
331 * sysdep.h: Now compiles on a Posix box
333 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
335 * icoff.c: Fix comment on big-endian version.
336 * coff-code.h: Make HAS_RELOC really work (it's backwards from
337 F_RELFLG). Set F_AR32WR in output files if little endian
340 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
342 * archures.c fixed =/== typo
344 * sunos.c added architecture stuff for output. Fixed
345 bug where files where vma(data) != size(text)
346 were processed wrong.
348 * coff-code.h added a lint cast
350 * (../include/a.out.sun4.h) fixed it so zmagic
353 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
355 * archive.c removed loads of includes, and fixed bug where string
356 table didn't have a null at the end.
358 * bfd.c fixed includes, added symbols argument to
359 canonicalize_reloc entry point.
361 * libbfd.c fixed includes and added some lint patches.
363 * targets.c added both sorts of intel coff.
365 * b.out.c fixed included, changed was the canonical
368 * icoff.c added support for callj and big and little
371 * opncls.c added chmod+xing for files with EXEC_P set.
373 * sunos.c fixed includes. Changed default section
374 alignement to words. Fixed relocation stuff to work with
377 * bfd.h various new types added, prototype for new
378 reloc calls, changed bfd->iostream to a void *
379 to including files don't need stdio.h.
381 * libcoff.h added conversion table to tie relocs to
386 * coff-code.h fixed includes. Added code to support
387 big and little endian formats. Various lints. Better
388 processing of symbols. Changed reloc stuff to new
391 * libbfd.h fixed includes
394 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
396 * bfd.h changed name of alignment entry in sec_struct to
397 alignment_power, because of conflicting uses within bfd.
398 Now it should be obvious that it's a 2**n alignment
399 specifier. Removed start_pad, end_alignment, block, minsize,
400 output_file_alignment, subsection_alignment and original_vma fields.
401 Added align_power() macro. Fixed bfd_section_alignment
402 acessor macros. Added bfd_symbol_same_target macro.
404 * b.out.c (b_out_write_object_contents) fixed to use
405 new alignment member. Fixed (callj_callback) to use section
406 relative symbols properly.
408 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
409 Fixed (translate_from_native_sym_flags) to correctly make
410 symbols section relative.
412 * bfd.c (bfd_errmsg) fixed various enum cast problems.
413 (bfd_make_section) took out initialization of obsolete members.
414 (bfd_print_symbol_vandf) added
416 * opncls.c (bfd_create) created.
418 * coff-code.h (coff_new_section_hook) took away refs
419 to obsolete members. (make_a_section_from_file) added
420 conversion between alignment types. (coff_symbol_from)
421 added. (coff_count_linenumbers) only counts linenumbers
422 if symbol is of coff-type. (coff_mangle_symbols) only
423 heavily mangles symbols if symbol is coff-type.
424 (coff_write_symbols) various lints. (coff_write_object_contents)
425 various lints and modification for alignment conversion.
426 (coff_slurp_relocs) fixed for use with new asection shape.
428 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
430 * archive.c lots of lint
432 * b.out.c added callj relocation support, upgrated reloc howto.
433 Fixed so that asymbol and reloc records are output
436 * bfd.c lots of lint, support for new bfd entry point
439 * bfd.h changed definition of asymbol to contain pointer to
440 owning bfd, removed target dependencies.
442 * cache.c took out print statements, put in BFD_ASSERT calls.
444 * coff-code.h various lints, corrected linenumber output
445 functionality. Added support for new style asymbols and
446 bfd_print_symbol. Fixed so that asymbol and
447 reloc records are handled correctly. Added timestamp.

460 and bfd_print_symbol.
462 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
464 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
465 pointer lint. Added support for callj relocation. Fixed bug where
466 the last 32 bytes of the text section were overwritten by data. Fixed bug
467 where archives of b.out didn't work due bfd_slurp_extended_name_table
470 * sunos.c added support for n_other field. Braced the howto table so
471 that it won't be affected by any lengthing of the howto struct typedef.
474 * bfd.h added support for n_other field, added special_function
475 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x

483 * ToDo: Create file for suggestions.
485 * Makefile: Support easy loading into Saber C.
486 Add dependencies for icoff.o and bcs88kcoff.o.
487 Rename coff.c to coff-code.h. Change callers.
489 * bfd.c (bfd_check_format): Allow the check_format routines
490 to return the desired target vector, rather than just a Boolean.
491 bfd.h (bfd_check_format): Change function pointer return type.
492 archive.c (bfd_generic_archive_p): change callee.
493 b.out.c (b_out_little_object_p, b_out_big_object_p,
494 b_out_real_object_p): change callee.
495 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
496 in check_format transfer vectors that need a filler.
497 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
498 bcs88kcoff.c: change callee.
499 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
500 icoff.c: change callee.
501 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
503 * libbfd.c (zalloc): It should actually zero the storage!
504 This was commented out for some reason.
506 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
507 This is so callers can avoid <stdlib.h> which doesn't exist
510 * bfd.c (map_over_sections): Add debugging code, since I
511 noticed the section count for sunos core files was bad, but only
512 GDB had detected the problem.
513 (bfd_set_section_lineno_size, bfd_set_section_linenos,
514 bfd_get_section_linenos): Remove obsolete functions.
515 (bfd_apply_relocations): Use longs, not ints, for the math.

518 as typedefs for them. Remove obsolete
519 bfd_get_section_lineno_size.
521 * cache.c: Make the "fdopen" support work. Keep better track
522 of how many files are open. Centralize the opening of files
523 and be sure bfd_open[rw] actually try to open the file. Evade
524 linked list initialization problems.
526 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
528 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
530 * cplus-dem.c: Delete file, since it is not part of BFD.
532 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
533 (bfd_openr, bfd_openw): Actually open the file, give error now.
535 * sunos.c (sunos4_core_file_p): Set section count.
536 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
537 obsolete definitions.
538 (_write_symbol_table): Initialize <idx> counter.
539 (foop): Eliminate debugging code.
