10 * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
14 Tue May 21 08:58:58 1991 Steve Chamberlain (steve at cygint.cygnus.com)
16 * opncls.c: Changed obstack_chunk_alloc use xmalloc
18 Mon May 20 17:12:17 1991 Steve Chamberlain (steve at cygint.cygnus.com)
20 * everything: Removed sysdep.h from bfd.h and put back into files
21 from which it was split out. Now 64 bit version is built with a
22 -DHOST_64_BIT="long long" on the compile line.
25 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
27 Changed all the [get|put][name] routines to use [get|put]_[size
30 Put in support for 64 bit work. Now two versions of bfd may be
31 generated, according to the state of TARGET_64_BIT, one which is
32 32 bit only, and one which is 64/32 bits.
33 Created new back end 'demo64' to test 64 bit functionality.
35 Renamed some files to work on DOS.
37 * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
38 64bit transfer * icoff.c: added 64bit transfer * ieee.c: name
39 chage, 64 bit transfer. * liba.out.h: Split out common code from
40 sunos and newsos into liba.out. Name changes and prototype mods. *

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

435 and bfd_print_symbol.
437 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
439 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
440 pointer lint. Added support for callj relocation. Fixed bug where
441 the last 32 bytes of the text section were overwritten by data. Fixed bug
442 where archives of b.out didn't work due bfd_slurp_extended_name_table
445 * sunos.c added support for n_other field. Braced the howto table so
446 that it won't be affected by any lengthing of the howto struct typedef.
449 * bfd.h added support for n_other field, added special_function
450 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x

458 * ToDo: Create file for suggestions.
460 * Makefile: Support easy loading into Saber C.
461 Add dependencies for icoff.o and bcs88kcoff.o.
462 Rename coff.c to coff-code.h. Change callers.
464 * bfd.c (bfd_check_format): Allow the check_format routines
465 to return the desired target vector, rather than just a Boolean.
466 bfd.h (bfd_check_format): Change function pointer return type.
467 archive.c (bfd_generic_archive_p): change callee.
468 b.out.c (b_out_little_object_p, b_out_big_object_p,
469 b_out_real_object_p): change callee.
470 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
471 in check_format transfer vectors that need a filler.
472 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
473 bcs88kcoff.c: change callee.
474 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
475 icoff.c: change callee.
476 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
478 * libbfd.c (zalloc): It should actually zero the storage!
479 This was commented out for some reason.
481 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
482 This is so callers can avoid <stdlib.h> which doesn't exist
485 * bfd.c (map_over_sections): Add debugging code, since I
486 noticed the section count for sunos core files was bad, but only
487 GDB had detected the problem.
488 (bfd_set_section_lineno_size, bfd_set_section_linenos,
489 bfd_get_section_linenos): Remove obsolete functions.
490 (bfd_apply_relocations): Use longs, not ints, for the math.

493 as typedefs for them. Remove obsolete
494 bfd_get_section_lineno_size.
496 * cache.c: Make the "fdopen" support work. Keep better track
497 of how many files are open. Centralize the opening of files
498 and be sure bfd_open[rw] actually try to open the file. Evade
499 linked list initialization problems.
501 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
503 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
505 * cplus-dem.c: Delete file, since it is not part of BFD.
507 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
508 (bfd_openr, bfd_openw): Actually open the file, give error now.
510 * sunos.c (sunos4_core_file_p): Set section count.
511 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
512 obsolete definitions.
513 (_write_symbol_table): Initialize <idx> counter.
