3 * Merge in changes from gdb-3.95 release.
4 Makefile.in: Allow hmake and tmake files to add OFILES.
6 bfd.c: support specific targets as well as searching. When
7 searching, take default target in preference to others.
9 ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
10 liba.out.h: Don't hard-code file offsets; use N_ macros for them.
11 libbfd.h: Support specific targets as well as searching.
12 opncls.c: Support specific targets as well as searching.
13 targets.c: Search is short-circuited if default target matches.
14 liboasys.c, libieee.c: Undo bothner changes that make macros
15 work to the left of assignment, but which depend on the
16 representations of different pointer types being the same.
18 Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
20 * i386coff.c: created.
21 * coffcode.h: added support for 386.
22 * Makefile.in: added support for 386.

31 Tue May 21 08:58:58 1991 Steve Chamberlain (steve at cygint.cygnus.com)
33 * opncls.c: Changed obstack_chunk_alloc use xmalloc
35 Mon May 20 17:12:17 1991 Steve Chamberlain (steve at cygint.cygnus.com)
37 * everything: Removed sysdep.h from bfd.h and put back into files
38 from which it was split out. Now 64 bit version is built with a
39 -DHOST_64_BIT="long long" on the compile line.
42 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
44 Changed all the [get|put][name] routines to use [get|put]_[size
47 Put in support for 64 bit work. Now two versions of bfd may be
48 generated, according to the state of TARGET_64_BIT, one which is
49 32 bit only, and one which is 64/32 bits.
50 Created new back end 'demo64' to test 64 bit functionality.
52 Renamed some files to work on DOS.
54 * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
55 64bit transfer * icoff.c: added 64bit transfer * ieee.c: name
56 chage, 64 bit transfer. * liba.out.h: Split out common code from
57 sunos and newsos into liba.out. Name changes and prototype mods. *

64 Added demo * aout32, aout64.c include aoutx.h * bout.c: used to
65 be called b.out.c * coffcode.h: used to be called coff-code.h, now
66 64bit ized. * demo64.c: 64 bit a.out back end
72 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
74 * libieee.h: Make ieee_data and ieee_ar_data macros usable
75 on LHS of assignment, even when using old compilers.
76 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
77 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
78 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
79 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
80 * targets.c: Add declaration of newsos3_vec.
83 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
85 * aout.c: fixxed some of the problems with filepos calculation.
86 (swap_ext_reloc): fixed problem with creation of relocs.
87 (aout_set_section_contents): fixed filepos problem
89 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
90 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
91 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
92 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
93 cleaned up. (coff_write_object_contents) cleaned up.
95 * ecoff.c: Totally different. Now supports ecoff fully.
97 * icoff.c: fixed problems in relocation callout.
99 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
101 * m68kcoff.c: updated target vector.
103 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
104 choose_reloc_size. (sunos4_write_object_contents) now calls
105 choose_reloc_size so outputs relocs correctly, also calculates the
106 size of the sections correctly.
110 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
112 Merge Per Bothner's changes to modularize BFD a.out a bit.
114 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
115 * ieee.c: Cast enums to int before comparing them, for brain-
117 * coff-code.h: Remove coff_get_section_contents, and use the
120 * aout.c: Derive new module from sunos.c, containing generic
121 support code for all kinds of a.out files.
123 * sunos.c: Remove all code that goes in aout.c. Split out
124 machine dependent followup in sunos4_object_p into
125 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
126 and redefine only the names we CHANGE, not all the names. Drop
127 the little-endian vector, and rename the vector as sunos4 rather
130 * b.out.c: Use aout.c routines for most of the work. Slight
131 changes for the new regime. Remove close_and_cleanup and
132 get_section_contents in favor of generics. New transfer vector
135 * newsos.c: New support for Sony NEWS, another a.out format.
137 * ecoff.c: Remove close_and_cleanup. New tvec regime.
138 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
139 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
141 * opncls.c (bfd_close): Call format-dependent write_contents
142 routine, if writing, before calling target-dependent
143 close_and_cleanup routine (which is now always generic, I think).
144 * srec.c: Use bfd_alloc instead of malloc. Remove
145 close_and_cleanup and move code from it to
146 srec_write_object_contents. Add write_contents to tvec.
147 * targets.c: Remove a.out little vector, replace a.out big
148 vector with SunOS vector. FIXME: Need Vax support again now.
150 * libbfd.h: Add write_contents format-dependent-vector to the
151 bfd_target vector. Supply a generic close_and_cleanup routine.
152 * liba.out.h: Handle the new aout.c split. Add prototypes for
153 all routines defined in aout.c. Rename "sunos" things to "aout"
154 things. Add a few fields where needed for various formats.
155 * Makefile.in: Add aout.c and newsos.c.
157 * archive.c, ieee.c, oasys.c: Lint.
159 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
162 changed forward declaration struct stat; to reduce warnings. Changed
163 comment on bfd_h_<x>_x.
165 * ../include/m68kcoff.h, ../include/intel-coff.h,
166 ../include/m88k-bcs.h
167 Now there are two incarnations of relocs, linenos and syments. One for
168 internal digestion, and one full of char arrays for I/O. The original
169 names have gone to detect errors.
171 * Makefile.in, m68kcoff.c, targets.c
172 Test new structure code with a 68k coff implementaion
174 * coff-code.h, icoff.c, coffswap.c, libcoff.h
175 Fixed all the places where there were problems with the size and
176 alignments of structures on disk and structures in memory. #ifed out
177 all the code in coffswap.c, since it should be done using the target
180 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
182 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
183 multiple reloc command.
185 * sunos.c (sunos4_set_section_contents): Made it so that sections
186 are always padded to their alignment size.
188 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
190 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
191 Clean up types and such (saber C problems).
192 * ecoff.c: Clean up types and such. Remove routines that are
193 not used. Fix up reading and swapping of shorts from files.
195 Notes on bfd-0.5.2-patch1a, from Per Bothner:
197 * a.out.vax.c: Remove two bogus "static" from prototypes.
199 * ecoff.c: Got rid of lots of non-working junk (that had
200 been copied directly from coff-code.h).
201 Updated to be consistent with updates to icoff.c and coff-code.h.
203 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
204 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
206 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
207 but until the target_vector is automatically generated,
208 it's as good as any. Note that the text offset is the only
209 difference between NewsOS and SunOs (including magic numbers).
210 (Most of the sunos_* routines should to renamed bsd_*
211 and move to a bsd.c file. Then (and when the target_vector
212 is automatically generated) it might make sense to create
213 a separate Sony target.)
215 * sysdep.h: Don't declare fread and fwrite. Causes trouble
216 on some systems, and doesn't help on others.
217 Similarly, only define X_OK if not already defined.
219 * trad-core.c: Don't include sys/stat.h - at least
220 on NewsOS 3, it has already been included.
222 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
224 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
225 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
226 symbol tables if necessary when reading them in, so gdb can use
227 them. Add "bfd_coff_" to the names so they won't conflict with
228 names in calling programs. FIXME-soon: if coff-code.h is
229 included in two BFD modules, this will cause duplicate
230 definitions; the routines should be exported to a separate,
231 common, module (probably along with a mess of other ones).
233 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
235 Improve modtime support.
237 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
238 Remove #define for bfd_get_mtime. Remove gratuitous comment.
239 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
240 BUG: archive members still do not get correct mod times.
242 Improve floating point support for core files.
244 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
245 (sunos4_core_file_p): Create a second registers section in the
246 core file, called ".reg2", for the float registers.
248 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
250 * many changes to improve archive handling; found a logic flaw in
251 bfd_check_format which only just happened to work by cooncidence.
253 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
255 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
258 * bfd.h: changed type of udata in asymbol to void *, like it
259 should be. Added bfd_reloc_dangerous enum member.
261 * coff-code.h: Fixed it so that internally generated symbols get
262 their values relocated correctly in all cases. Removed calls to
265 * icoff.c: Not understanding the destination symbol of a reloc is
266 not a failure any more, just 'dangerous'. This allows linking of
267 b.out and coff images.
269 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
273 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
275 * sunos.c (translate_to_native_sym_flags): fixed
276 sym_pointer->n_value so that symbols on the way out get their
277 section relative values calculated correctly.
279 * coff-code.h (mangle_symbols): fixed problem where tags were not
280 being relocated for structs, enums, unions. Also various lints.
282 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
284 * archive.c (get_elt_at_filepos): system_call_error returned
287 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
289 * Resolve the use of no_error and system_call_error.
290 The bfd library itself now will never set bfd_error to
293 The code still needs to be combed to make sure all the error
294 codes are correct. I suspect they are not always set correctly.
296 * The names of all the messages have _ prepended because the sun
297 bundled compiler can't distinguish from a macro which takes an
298 argument and the same identifier in a non-macro context.
300 * The reason for the above being that entry points which used to
301 be trampoline functions are now just macros which expand to a
302 direct call through the bfd's xfer vector.
304 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
305 must gas have its own version of everything (the gas version
306 had the correct value)
308 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
310 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
311 properly support i960 architecture and output correct reloc stuff.
313 * bfd.h: added prototype for bfd_printable_arch_mach, added
316 * coff-code.h: Applied patches from chrisb to support i960
317 architecture, zero relocs and swap them correcly and conditionally
318 compiled the timestamp.
320 * sunos.c: Made the default section alignment 2^3 so that doubles
321 are done properly. Fixed the same reloc bug that was in b.out.c
323 * sysdep.h: Now compiles on a Posix box
325 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
327 * icoff.c: Fix comment on big-endian version.
328 * coff-code.h: Make HAS_RELOC really work (it's backwards from
329 F_RELFLG). Set F_AR32WR in output files if little endian
332 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
334 * archures.c fixed =/== typo
336 * sunos.c added architecture stuff for output. Fixed
337 bug where files where vma(data) != size(text)
338 were processed wrong.
340 * coff-code.h added a lint cast
342 * (../include/a.out.sun4.h) fixed it so zmagic
345 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
347 * archive.c removed loads of includes, and fixed bug where string
348 table didn't have a null at the end.
350 * bfd.c fixed includes, added symbols argument to
351 canonicalize_reloc entry point.
353 * libbfd.c fixed includes and added some lint patches.
355 * targets.c added both sorts of intel coff.
357 * b.out.c fixed included, changed was the canonical
360 * icoff.c added support for callj and big and little
363 * opncls.c added chmod+xing for files with EXEC_P set.
365 * sunos.c fixed includes. Changed default section
366 alignement to words. Fixed relocation stuff to work with
369 * bfd.h various new types added, prototype for new
370 reloc calls, changed bfd->iostream to a void *
371 to including files don't need stdio.h.
373 * libcoff.h added conversion table to tie relocs to
378 * coff-code.h fixed includes. Added code to support
379 big and little endian formats. Various lints. Better
380 processing of symbols. Changed reloc stuff to new
383 * libbfd.h fixed includes
386 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
388 * bfd.h changed name of alignment entry in sec_struct to
389 alignment_power, because of conflicting uses within bfd.
390 Now it should be obvious that it's a 2**n alignment
391 specifier. Removed start_pad, end_alignment, block, minsize,
392 output_file_alignment, subsection_alignment and original_vma fields.
393 Added align_power() macro. Fixed bfd_section_alignment
394 acessor macros. Added bfd_symbol_same_target macro.
396 * b.out.c (b_out_write_object_contents) fixed to use
397 new alignment member. Fixed (callj_callback) to use section
398 relative symbols properly.
400 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
401 Fixed (translate_from_native_sym_flags) to correctly make
402 symbols section relative.
404 * bfd.c (bfd_errmsg) fixed various enum cast problems.
405 (bfd_make_section) took out initialization of obsolete members.
406 (bfd_print_symbol_vandf) added
408 * opncls.c (bfd_create) created.
410 * coff-code.h (coff_new_section_hook) took away refs
411 to obsolete members. (make_a_section_from_file) added
412 conversion between alignment types. (coff_symbol_from)
413 added. (coff_count_linenumbers) only counts linenumbers
414 if symbol is of coff-type. (coff_mangle_symbols) only
415 heavily mangles symbols if symbol is coff-type.
416 (coff_write_symbols) various lints. (coff_write_object_contents)
417 various lints and modification for alignment conversion.
418 (coff_slurp_relocs) fixed for use with new asection shape.
420 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
422 * archive.c lots of lint
424 * b.out.c added callj relocation support, upgrated reloc howto.
425 Fixed so that asymbol and reloc records are output
428 * bfd.c lots of lint, support for new bfd entry point
431 * bfd.h changed definition of asymbol to contain pointer to
432 owning bfd, removed target dependencies.
434 * cache.c took out print statements, put in BFD_ASSERT calls.
436 * coff-code.h various lints, corrected linenumber output
437 functionality. Added support for new style asymbols and
438 bfd_print_symbol. Fixed so that asymbol and
439 reloc records are handled correctly. Added timestamp.

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

475 * ToDo: Create file for suggestions.
477 * Makefile: Support easy loading into Saber C.
478 Add dependencies for icoff.o and bcs88kcoff.o.
479 Rename coff.c to coff-code.h. Change callers.
481 * bfd.c (bfd_check_format): Allow the check_format routines
482 to return the desired target vector, rather than just a Boolean.
483 bfd.h (bfd_check_format): Change function pointer return type.
484 archive.c (bfd_generic_archive_p): change callee.
485 b.out.c (b_out_little_object_p, b_out_big_object_p,
486 b_out_real_object_p): change callee.
487 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
488 in check_format transfer vectors that need a filler.
489 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
490 bcs88kcoff.c: change callee.
491 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
492 icoff.c: change callee.
493 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
495 * libbfd.c (zalloc): It should actually zero the storage!
496 This was commented out for some reason.
498 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
499 This is so callers can avoid <stdlib.h> which doesn't exist
502 * bfd.c (map_over_sections): Add debugging code, since I
503 noticed the section count for sunos core files was bad, but only
504 GDB had detected the problem.
505 (bfd_set_section_lineno_size, bfd_set_section_linenos,
506 bfd_get_section_linenos): Remove obsolete functions.
507 (bfd_apply_relocations): Use longs, not ints, for the math.
509 * bfd.h: Declare enum boolean and struct bfd_target as well
510 as typedefs for them. Remove obsolete
511 bfd_get_section_lineno_size.
513 * cache.c: Make the "fdopen" support work. Keep better track
514 of how many files are open. Centralize the opening of files
515 and be sure bfd_open[rw] actually try to open the file. Evade
516 linked list initialization problems.
518 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
520 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
522 * cplus-dem.c: Delete file, since it is not part of BFD.
524 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
525 (bfd_openr, bfd_openw): Actually open the file, give error now.
527 * sunos.c (sunos4_core_file_p): Set section count.
528 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
529 obsolete definitions.
530 (_write_symbol_table): Initialize <idx> counter.
