1 Fri Nov 22 08:11:42 1991 John Gilmore (gnu at cygnus.com)
4 * host-aout.c, trad-core.c: Fix write_armap prototypes. Lint.
6 Thu Nov 21 19:56:40 1991 Per Bothner (bothner at cygnus.com)
8 * stab-syms.c, syms.c: Moved bfd_stab_name() and bfd_stab_names[]
9 from syms.c to new file stab-syms.c. Also, since GNU extended
10 type codes such as N_SETT are no longer in ../include/stab.def,
11 include them manually.
12 * stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
13 bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
14 * libaout.h: Added prototype for aout_stab_name().
15 * Makefile.in: Update Makefile for new stab-syms.[co].
17 Thu Nov 21 11:50:49 1991 John Gilmore (gnu at cygnus.com)
19 * libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this
20 rather complicated seeming problem. Eliminate LOGICAL_ versions,
21 just make N_XXX work by excluding the header from the text segment.
22 * aoutx.h: Fix comments to match.
24 Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
26 * libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
27 LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
28 for the "logical" text segment (i.e. never consider the exec
29 header to be part of the text segment). This change is
30 needed for consistency with various other parts of bfd and ld.
31 * aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
32 and move calculation of obj_textsec(abfd)->size to libaout.h.
33 * bfd-in.h: Removed bogus ';'.
35 * Makefile.in: Add MINIMIZE flag to select lean
36 or bloated target_vector.
37 * targets.c: Use new MINIMIZE macro, and add trad_core if needed.
38 * newsos3.c: Fixes to ../include/aout64.h remove need
39 for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
41 Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
43 * aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h
44 handle both little and big-endian targets, with little
45 the default unless TARGET_IS_BIG_ENDIAN_P is defined.
46 * host-aout.c: Add FIXME note.
48 Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
50 * targets.c: Make the default target_vector contain
51 just &DEFAULT_VECTOR. This makes executables a lot smaller.
52 Old behavior can be gotten by defining ALL_TARGETS.
53 * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
54 Factored out common code into new file aout-target.h.
55 Saves a lot of duplicate code for a.out variants.
57 Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)
59 Get 'make headers' to work when configured with +subdirs.
60 * Makefile.in: Add $(subdir) to docdir path.
61 * doc/Makefile.in (protos): Add $(srcdir) prefix
62 to name of sed scripts.
64 Thu Nov 14 19:49:10 1991 Per Bothner (bothner at cygnus.com)
66 * aoutx.h (NAME(aout,print_symbol)): Fix thinko.
67 * syms.c (bfd_stab_names): Turn on new GNU_EXTRA_STABS macro
68 to include names of N_SETT etc.
70 Thu Nov 14 19:11:13 1991 Fred Fish (fnf at cygnus.com)
72 * elf.c: Add minimal support for ELF symbol tables. Generates
73 canonical bfd symbol tables from ELF symbol tables. Change the
74 name of some functions from bfd_<name> to elf_<name>.
76 * syms.c: Trivial fix to comment to remove a redundant "to".
78 Wed Nov 13 17:02:01 1991 John Gilmore (gnu at cygnus.com)
80 * coff-{i386,m68k,m88k}.c: Change name of file format to standard
81 form that GDB recognizes as COFF.
83 Wed Nov 13 09:09:41 1991 Steve Chamberlain (sac at cygnus.com)
85 * ieee.c (ieee_object_p): cast NULL correctly.
86 * configure.in: added harris host
88 * coff-a29k.c: Lots of changes, most from David Wood.
90 Tue Nov 12 07:21:41 1991 John Gilmore (gnu at cygnus.com)
92 * coff-m88k.c (coff_write_armap): Just #undef it.
94 Mon Nov 11 20:30:18 1991 Steve Chamberlain (sac at cygnus.com)
96 * Makefile.in: standardize on MINUS_G to disable debugging
97 * coff-m88k.c: create coff armaps instead of bsd ones.
98 * opncls.c (bfd_close_all_done), (bfd_close): Mask out random bits
101 Mon Nov 11 19:07:32 1991 Fred Fish (fnf at cygnus.com)
103 * elf.c: Additions to support ELF format core files.
104 * config/mh-amix: Add -DHAVE_PROCFS to HDEFINES, since host
105 has support for /proc (all the include files in particular).
107 Mon Nov 11 18:36:47 1991 Per Bothner (bothner at cygnus.com)
109 * aoutx.h (NAME(aout,find_nearest_line)): Handle the case
110 of two N_SO stabs, one for directory, and one for filename.
112 * bfd-in.h (print_vma): Factor out duplicate definition.
114 Exit a little more gracefully when malloc returns NULL.
115 * libbfd.c: New function bfd_xmalloc (malloc wrapper).
116 * opncls.c, syms.c, bout.c, aoutx.h: Replace malloc by bfd_xmalloc.
117 * libbfd.h: Rre-generated due to libbfd.c update.
119 Sat Nov 9 13:45:01 1991 Fred Fish (fnf at cygnus.com)
121 * config/mt-m68k-elf: Define DEFAULT_VECTOR as elf_big_vec.
123 * elf.c (elf_object_p): Don't try to create a bfd section for
124 the first ELF section header. It is just a placeholder.
126 Sat Nov 9 03:04:26 1991 John Gilmore (gnu at cygnus.com)
128 * coff-rs6000.c, config/mh-rs6000: Make it work on archive and
129 core files, when compiling native.
130 * hosts/h-rs6000.h: Define FASCIST_FDOPEN for bfd_fdopenr.
132 FIXME: The aoutf1.h change below needs to be reversed back
135 Thu Nov 7 11:03:55 1991 Steve Chamberlain (sac at rtl.cygnus.com)
137 * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
138 manipulation of lnno fields in lineno structs in a coff-<f>.h
139 independent way. Override it in coff-<f>.h to your favourite
140 number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
141 (coff_swap_lineno_out): modified to use the new macros.
143 Mon Nov 4 11:38:33 1991 Steve Chamberlain (sac at cygnus.com)
145 * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
146 unknown arch when the magic number doesn't specify the
147 architecture, since some OSs (eg old sun3s) don't set the number, and
148 020 is probably the right answer anyway.
150 Sun Nov 3 12:07:08 1991 Per Bothner (bothner at cygnus.com)
152 * hosts/h-news.h, hosts/h-rtbsd.h:
153 Get rid of MISSING_VFPRINTF, since libiberty provides one.
154 * bfd-in.h (bfd_print_symbol_type_hopw enum): Add new option
155 bfd_print_symbol_nm, for use by nm.
156 * aoutx.h (NAME(aout,print_symbol)): Add code for new
157 bfd_print_symbol_nm option, to print in nm format.
158 * coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
159 oasys.c (oasys_print_symbol): Provide stub implementations
160 for bfd_print_symbol_nm.
161 * syms.c: New function bfd_decode_symclass, used by nm printer.
162 New function bfd_stab_name to look up string name of stab code.
164 Sat Nov 2 14:26:03 1991 Steve Chamberlain (steve at cygnus.com)
166 * Makefile.in: Added ctor.c
167 * archures.c (bfd_default_arch_struct) added
168 bfd_default_reloc_type_lookup.
169 * coffcode.h: removed a load of #if 0ed code.
170 (coff_compute_file_section_positions): now works out the section
171 alignment and size correctly in all cases.
172 (coff_get_symtab): looks for constructor symbols and calls the
173 right function when they're found. (coff_canonicalize_reloc):
174 knows when a section is full of constructors and does the right
176 * cpu-m88k.c: Added default_reloc_type lookup to the architecture
178 * libbfd-in.h: (bfd_default_reloc_type_lookup) defun added.
179 * libcoff.h: removed #if 0ed code
180 * reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
181 arch independent constructor relocation type.
182 (bfd_reloc_type_lookup): removed the comment "this will go away"
183 since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
184 reloc which is used when BFD_RELOC_CTOR falls through to give a
185 default 32bit reloc for constructors.
186 (bfd_default_reloc_type_lookup): added.
187 * aoutf1.h: fixed SEGMENT_SIZE typo.
189 Thu Oct 31 18:23:06 1991 John Gilmore (gnu at cygnus.com)
191 * coff-rs6000.c: Change name to "aixcoff-rs6000", to avoid
192 matching prefix "coff".
193 * coffcode.h (coff_swap_aux_in, coff_swap_aux_out): Handle
194 rs/6000 csect records.
196 Sun Oct 27 16:56:58 1991 Steve Chamberlain (steve at cygnus.com)
198 * coff-m88k.c, targets.c: change name of m88k_bcs to m88kbcs
199 * configure.in: add motorola delta88 cases
200 * libbfd.h, libbfd-in.h, archive.c, ieee.c, elf.c, srec.c: fix
201 write_armap prototype
202 * libbfd.c: add doc on bfd_write_bigendian_4byte_int
204 Fri Oct 25 02:48:19 1991 John Gilmore (gnu at cygnus.com)
206 * Rename COFF-related files in `coff-ARCH.c' form.
207 coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
208 coff-mips.c, coff-rs6000.c to be exact.
210 * Makefile.in: Only supply TARGET_DEFAULTS to targets.c, reducing
212 * config/mt-*: Ditto.
214 Thu Oct 24 22:40:07 1991 John Gilmore (gnu at cygnus.com)
216 RS/6000 support, by Metin G. Ozisik, Mimi Phûông-Thåo Võ, and
217 John Gilmore. Archive support from Damon A. Permezel.
219 * Makefile.in: Add cpu-rs6000.c and rs6000coff.c.
220 * configure.in: Add rs6000 case.
221 * targets.c: Add rs6000 vector.

225 * bfd.c (bfd_errmsgs): Add no_debug_section error message.
226 * section.c (bfd_make_section): Return NULL on attempt to create
228 * coffcode.h (bfd_swap_reloc_in): Handle r_type and r_size.
229 (bfd_swap_aouthdr_in): Handle lots more members.
230 (make_a_section_from_file): If section has already been seen,
231 just return false rather than overwriting it.
232 (coff_real_object_p): Understand incoming magic numbers.
233 (coff_set_flags): Understand outgoing magic numbers.
234 (coff_compute_section_file_positions): outgoing aouthdr magic #.
235 (build_debug_section): Add fn for reading debug string section.
236 (get_normalized_symtab): Handle symbol names in debug string section.
237 Remove unused obj_string_table.
238 (coff_slurp_symbol_table): Handle rs6000-specific storage classes.
239 * aoutx.h (translate_from_native_sym_flags, N_SET*): Check for
240 existing section before making one.
241 * cpu-rs6000.c: New file.
242 * rs6000coff.c: New file.
244 Thu Oct 24 02:03:24 1991 Fred Fish (fnf at cygnus.com)
246 * elf.c: Add partial support for ELF format corefiles. Still needs
247 support for extracting registers from corefiles.
249 * config/t-m68k-elf: Set DEFAULT_VECTOR to elf_big_vec.
251 * config/{h-amix,h-dgux,h-irix3,h-ultra3}: For systems where
252 RANLIB is defined as echo, send the output to /dev/null to help
253 reduce clutter in the output from doing a make.
255 Mon Oct 21 17:48:48 1991 John Gilmore (gnu at cygnus.com)
257 * hosts/h-vaxult.h: Remove malloc/free decls covered in stdlib.h.
258 Fix HOST_PAGE_SIZE and HOST_SEGMENT_SIZE. From David Taylor.
260 Mon Oct 21 09:34:11 1991 Steve Chamberlain (steve at rtl.cygnus.com)
262 * coffcode.h (coff_compute_section_file_positions): make it pad
263 section size out if there are alignment restrictions so that the
264 image will be ok on a system where section positions are worked
265 out by accumulating sizes rather than from the section headers.
266 * targets.c (proto write_armap). Changed orl_count to unsigned.
267 * opncls.c (bfd_close_all_done). Added so that generative
268 programs like gas can close a bfd without causing bfd confusion.
269 * libbfd.h (changed becuase of protos)
270 * amdcoff.c: messed with the way that jmp displacements are
271 calcualated. This may not yet be totally correct.
272 * archive.c (coff_write_armap): rewrote the way that ranlibs are
274 * coffcode.h (fixup_symbol_value): now doesn't core dump if a non
275 abs symbol has no section (like a register symbol).
276 (coff_write_symbol) now zeros auxent before filling it up to help
277 with sensitive applications.
278 * libbfd.c (bfd_write_bigendian_4byte_int): added.
280 Wed Oct 16 22:58:45 1991 John Gilmore (gnu at cygnus.com)
282 * bfd.c: Make sure we don't get a macro strerror().
283 * opncls.c (bfd_fdopenr): If FASCIST_FDOPEN, use "r", not "r+".
284 * trad-core.c (trad_unix_core_file_failing_command): Suppress
285 attempt to recover command, ifdef NO_CORE_COMMAND.
286 * hosts/h-tahoe.h: Add FASCIST_FDOPEN and NO_CORE_COMMAND;
288 * hosts/h-i386v.h: Use <utime.h>, not <sys/utime.h>, unlike POSIX.
290 Wed Oct 16 12:43:49 1991 Per Bothner (bothner at cygnus.com)
292 * archive.c (bsd_write_argmap): The size of the ranlib structures
293 should not include the size field itself.
294 * aoutx.h, libaout.h (NAME(aout, sizeof_headers)): Use
295 adata(abfd)->exec_bytes_size field instead of constant macro,
296 because aoutx.h compiles to a simple .o file shared by
297 all 32-bits a.out targets.
299 Wed Oct 16 11:11:05 1991 John Gilmore (gnu at cygnus.com)
301 * configure.in: Allow i386-sco-sysv.
302 * bout.c: Remove unused i960_align; lint dummy core file handlers.
305 * host-aout.c: New strategy. We use common code, include files,
306 and data structures to handle the file, but set a few parameters
307 from the host's config file (page size, text start addr, etc).
308 * libaout.h: Define HP BSD machine types.
309 * aoutf1.h: Handle reading a.outs with these types.
311 * trad-core.c: Pass the u.u_ar0 value as the negative of the
312 virtual-memory-address of the .reg section. We can't just make a
313 section for "all the regs and nothing else" because only GDB knows
314 exactly where the regs are (scattered around the upage and stack).
315 Clean up memory allocation. Remove big- and little-endian
316 vectors, replace with single vector; this only runs on the host,
317 in host byte order. Replace byteswap routines with aborts in case
319 * targets.c: There's only one trad_core_vec now.
320 * aoutf1.h (sunos_core_file_p): VMA of .reg* now needs to be 0.
322 Tue Oct 15 08:29:03 1991 John Gilmore (gnu at cygnus.com)
324 * hosts/h-amix.h (free): Fix prototype.
326 * aoutx.h: Don't use NULL as an integer, for braindead systems
327 that declare it as (void *)0. (From Peter Schauer.)
329 Mon Oct 14 17:20:47 1991 Per Bothner (bothner at cygnus.com)
331 * opncls.c (bfd_fdopenr): Add parentheses to avoid reported
332 problem with bad Ultrix system headers.
333 * aoutx.h (NAME(aout,set_section_contents)): Try to handle the
334 various kinds of alignments for the various kinds of
337 Mon Oct 14 14:23:10 1991 John Gilmore (gnu at cygnus.com)
339 * doc/Makefile: Don't assume . is on the path (from James Clark).
341 Fri Oct 11 22:45:14 1991 John Gilmore (gnu at cygnus.com)
343 * Makefile.in: Avoid Sun Make VPATH bugs.
344 * targets.c: Declare trad_core vectors extern.
346 Fri Oct 11 13:03:02 1991 Per Bothner (bothner at cygnus.com)
348 * coffcode.h: Moved ALIGN macro to libbfd.h. Removed i960_align.
349 * libbfd.h: Moved ALIGN macro here.
350 * bout.c (b_out_callback): Replace i960_align by align_power.
352 * libaout.h (struct aoutdata): Added fields page_size,
353 segment_size and exec_bytes_size. These help generic code
354 (in aoutx.h and libaout.h) to figure out where to align
355 the various segments in a demand paged file.
356 * libaout.h (WRITE_HEADER): Use new (struct aoutdata) fields
357 to decide if the exec header counts in a_text (text segment size).
358 Also, assume D_PAGED flag is set; don't set it here.
359 * bout.c (b_out_callback): Add initialization of
360 adata fields page_size, segment_size, and exec_bytes_size.
361 * host-aout.c (NAME(host_aout, callback) and
362 NAME(host_aout,mkobject): Ditto.
363 * i386aout.c (aout386_callback) and new aout386_mkobject): Ditto.
364 * newos3.c (newsos3_callback) and new newsos_mkobject): Ditto.
365 * aoutf1.c (sunos4_callback) and new sunos_mkobject): Ditto.
366 * aoutx.h (NAME(aout,some_aout_object_p)): Don't subtract
367 EXEC_BYTES_SIZE from the a_test size; this is only appropriate
368 for some systems (mainly sunos), so do it in the callback instead.
369 Same routine: Add stuff to the THIS_IS_ONLY_DOCUMENTATION comment.
370 * aoutx.h (NAME(aout,set_section_contents): Change the way
371 filepos and size of sections are carried out to support
372 older styles of demand paged executables.
375 Fri Oct 11 12:33:36 1991 Steve Chamberlain (steve at cygnus.com)
377 * bfd-in.h: Added more macros to COFF_SWAP_TABLE.
378 * bfd.c: Added macros to enable gas to swap coff records.
379 * coffcode.h: Make the coff_swap_*_out routines return the number
380 of bytes swapped, and cleaned up their prototypes.
381 * configure.in: Added ebmon/coff support
382 * ecoff.c: Changed null definitions of coff_swap_*_out to conform
384 * targets.c: Added new entry points for coff swapping
386 Fri Oct 11 03:01:52 1991 John Gilmore (gnu at cygnus.com)
388 Restructure configuration scheme for bfd, binutils, ld.
390 * include/sys/h-*.h: Move to bfd/hosts/h-*.h.
391 * configure.in: Revise to symlink sysdep.h to hosts/h-xxx.h.
392 Change some config names to match other dirs.
393 * *.c: Include bfd.h before sysdep.h, so ansidecl and PROTO()
395 * Makefile.in: Use -I. to get sysdep.h. Remove refs to
397 * cpu-i960.c: Strncmp needed a length arg.
398 * ecoff.c: Don't ever call trad_unix_core_file_p from here.
399 * i386aout.c: Remove dead N_TXTOFF override.
400 * trad-core.c: Don't disable the whole file if SUN4_SYS.
401 * config/: Rename some config files to match up h-*.h names.
402 Remove all the HOST_SYS definitions from the config files.
403 * hosts/h-amix.h, h-i386v.h: Define POSIX_UTIME, not USG.
404 * hosts/h-hp9000.h: Remove USG comment.
405 * hosts/h-rs6000.h: Include <stdlib.h> for malloc.
406 * hosts/h-news.h, h-sparc-64.h: New config files that had
407 previously been kludged in the <sysdep.h> file.
409 Thu Oct 10 17:54:08 1991 John Gilmore (gnu at cygnus.com)
411 * config/*: trad-core support is HOST dependent, not target
412 dependent. Target config files only set DEFAULT_VECTOR and/or
413 other vector elements. Exception: when host-aout.c is in use,
414 in which case we're forced to assume we're native (hp, vax,
415 tahoe). Rename XDEPFILES to HDEPFILES.
416 * Makefile.in: Rename XDEPFILES.
417 * config/h-sun*: Don't force static linking.
418 * trad-core.c: Document how to use it nowadays.
419 * i386aout.c, newsos3.c: Clean up.
420 * i386coff.c: Allow 386 coff files to be used as core files too
421 (for reading core files from embedded systems).
423 Tue Oct 8 15:30:39 1991 John Gilmore (gnu at cygnus.com)
425 * Add i386aout.c for a.out support on the i386.
427 Tue Oct 8 12:18:54 1991 Roland H. Pesch (pesch at cygnus.com)
429 * reloc.c, section.c, syms.c, targets.c: correct info-node
430 structure in *doc* comments.
431 doc/Makefile: stop hiding complaints from makeinfo.
433 Sun Oct 6 19:10:06 1991 John Gilmore (gnu at cygnus.com)
435 * aoutx.h (...some_aout_object_p): Take a third parameter,
436 the internal_exec struct, and avoid ever looking at an
437 external_exec. All callers changed to read the entire
438 external_exec struct, swap and check its magic number,
439 swap in the whole structure, and pass the swapped-in version to
441 * bout.c: Bring into modern era. Use single _object_p routine
442 for big- aand little-endian. Provide internal and external
443 exec header structs. Use separate swap-in and swap-out routines.
445 * libaout.h: Move struct internal_exec from ../include/aout64.h
446 to here. Add obj_symbol_entry_size to struct aoutdata.
447 * aoutx.h (...some_aout_object_p): Set obj_symbol_entry_size.
449 * ../include/aout64.h: Change EXTERNAL_LIST_SIZE to
450 EXTERNAL_NLIST_SIZE. Callers changed.
452 Fri Oct 4 18:18:46 1991 John Gilmore (gnu at cygnus.com)
454 * bfd.c: Remove strerror() to libiberty.
456 * elf.c: Remove elf_set_section_contents, use generic one. Lint.

463 * archures.c: Rename `struct bfd_arch_info_struct' to `struct
464 bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
465 `bfd_arch_info_type'. All uses changed.
466 * reloc.c: Rename `bfd_reloc_status_enum_type' to
467 `bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
468 to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
469 it needs a better name.) All uses changed.
470 * targets.c: Rename `enum target_flavour_enum' to `enum
471 target_flavour', and remove the `_enum' from all of the enum
472 values themselves. All uses changed.

489 Thu Oct 3 19:39:55 1991 John Gilmore (gnu at cygnus.com)
491 * bfd-in.h: enum boolean => enum bfd_boolean for SVR4. Gumby's
492 prediction is vindicated!
494 * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
495 Remove refs to howto.c, since Steve forgot.
497 Thu Oct 3 07:49:21 1991 Steve Chamberlain (steve at cygnus.com)
499 * elf.c: took the abort out of set_arch_mach so that objdump -i will
500 still work. Now allows any architecture/machine to be set.
502 Wed Oct 2 13:50:35 1991 Steve Chamberlain (steve at cygnus.com)
504 * howto.c deleted and moved code to reloc.c
506 * libbfd.h, libbfd-in.h removed $id stuff for real
508 * cpu-h8300.c Made it match various different spellings of h8300.
510 * archures.c: Took out the first char filter which made it only
511 look for a cpu/arch match when the first chars of supplied and
512 tested names were the same.
514 * targets.c removed oasys stuff, pending someone to fix the bugs
518 Tue Oct 1 12:29:44 1991 John Gilmore (gnu at cygnus.com)
520 * Makefile.in, configure.in, targets.c, elf.c: Add preliminary
521 ELF support good enough for GDB.
522 * configure.in, config/h-amix, config/t-m68k-elf: Handle
523 m68k-cbm-svr4 host and target.
524 * config/t-m68k-coff, t-m88k-coff, t-m88k-aout: Make files nonempty
525 so `diff' and `patch' can cope.
527 Tue Oct 1 11:24:31 1991 Steve Chamberlain (steve at cygnus.com)
529 * archures.c: removed texinfo error
531 * init.c: added texinfo hooks, and removed initialization error
534 * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
537 Tue Oct 1 05:02:53 1991 John Gilmore (gnu at cygnus.com)
539 * cpu-i960.c: Avoid numerical count of initializers.
541 Vax Ultrix changes from David Taylor <taylor@think.com>:
542 * host-aout.c: Make little-endian vector really little-endian.
543 * configure.in: Separate vax and tahoe cases, handle ultrix.
544 * config/t-vax: Add trad-core.o.
545 * config/h-vaxult: New host system.
547 Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
549 * bfd-in.h VERSION, change version number to 0.18, this makes a
550 gap, but now is the same as the linker version number.
552 * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
553 cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
554 files will eventually contain processor specific bits for bfd,
555 like strange relocation information and dis/assembly. So far only
556 the H8 has been even partially done. This work also ties in with
557 the change in handling architectures.
559 * amdcoff.c: (a29k_reloc) fix error message.
561 * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
562 discover the architecture of the bfd. (sunos4_callback) calls the
563 function bfd_set_arch_mach rather than stuffing stuff directly
564 into the bfd. (sunos4_write_object_contents), changed names of
567 * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
568 setup the environment.
570 * archive.c: (bfd_slurp_coff_armap) coff archives always have the
571 headers in big endian format, regardless of the endianess of the
574 * archures.c: totally changed. Now an architecture is represented
575 with a pointer to an info structure rather than an enumerated type
576 and a long. The old info is available as two elements in the
577 structure. Future enhancements to architecure support will
578 involve pointers to methods being placed into the info structure.
580 * bfd.c: changed the definition of the bfd structure for the new
583 * bout.c: (b_out_set_arch_mach) changed to use the new
584 architecture mechanism.
586 * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
587 the new architecture mechanism.
589 * configure.in: added h8 stuff.
591 * ieee.c: too many changes to note. Now ieee files written with
592 bfd gas and ld can be read by gld and ieee only linkers and
595 * libbfd.c, libbfd.h: changed prototype of bfd_write.
597 * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
598 than fixing the structure directly.
600 * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
601 than fixing the structure directly.
603 * opncls.c: (new_bfd) makes sure that bfd_init has been called
604 before opening a bfd.
606 * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
607 rather than fixing the structure directly.
609 * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
610 in the t/hmake file) a user can select which backends they want
611 linked with bfd without changing the source.
613 * init.c: new, looks after initializing modules.
615 * howto.c: for future use, will allow an application to work out
616 what cookie to use as a handle on a relcoatio howto.
618 Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
620 * srec.c: Better error checking, partly from Peter Schauer.
621 (srec_object_p): Avoid assuming any file that starts with 'S' is
622 an S-record file! (Check for 3 uppercase-hex digits after it.)
623 (ISHEX): Define new macro for checking supposedly hex characters.
624 (pass_over): Treat as EOF any S-record line that:
625 * doesn't have hex in either size character
626 * produces a size larger than 0x7F
627 * has an unrecognized type number
629 Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
631 * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
632 opncls.c: Lint (saber actually).
634 Thu Sep 26 11:24:24 1991 Per Bothner (bothner at cygnus.com)
636 * libaout.h (WRITE_HEADERS): Set header's a_text field always.
637 * newsos3.c: Fixed two types: newos3 -> newsos3.
638 * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
639 to use correct segment.
641 Mon Sep 23 18:24:34 1991 Per Bothner (bothner at cygnus.com)
643 * aoutx.h (print_symbol): Handle missing symbol->name.
645 Fri Sep 20 12:26:01 1991 Stu Grossman (grossman at cygnus.com)
647 * aoutf1.h (swapcore_sparc): Change name of USRSTACK, fix comment
650 Tue Sep 17 17:23:49 1991 Stu Grossman (grossman at cygnus.com)
652 * oasys.c, configure.in, config/h-irix3, config/t-irix3:
653 add sgi/irix support.
655 Thu Sep 12 14:29:09 1991 John Gilmore (gnu at cygint.cygnus.com)
657 Changes for the AMD 29000 Ultracomputer port from David Wood.
660 * opncls.c (bfd_fdopenr): Handle NO_FCNTL.
662 * Makefile.in: Make subdirs work by using $(INCDIR) in the
665 * coffcode.h (coff_real_object_p): Pass information about the
666 current file's coff symbol format to BFD via the coff_data struct.
667 (coff_find_nearest_line): obj_icof => coff_data.
668 (coff_swap_sym_{in,out}): Check that SYMNMLEN == E_SYMNMLEN.
669 (coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
670 and DIMNUM == E_DIMNUM.
671 * configure.in: Handle a29k-*-* hosts, and targets
672 a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
673 * libcoff-in.h: Add local_n_btmask, local_n_btshft,
674 local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
675 local_linesz to `coff_data' (tdata) struct.
676 (coff_data, coff_data_type, coff_tdata): Rename struct icofdata.
677 * config/h-ultra3: Handle a29k-*-* hosts as Ultracomputers.
679 Thu Sep 12 14:07:22 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
681 * Makefile.in: $(MAKE) for make, $(docdir) for doc
682 * doc/Makefile: redundant dependencies for Sun-make VPATH bug
684 Tue Sep 10 20:34:12 1991 John Gilmore (gnu at cygint.cygnus.com)
686 * aoutf1.h (sunos4_core_file_p): Release the right storage in

698 * aoutx.h (aout_set_section_contents): On first output, check
699 abfd->direction and complain if erroneous.
701 * Makefile.in: Add crude dependencies.
703 Tue Sep 3 13:46:19 1991 Steve Chamberlain (steve at cygint.cygnus.com)
705 * config/* aoutx.h configure* shortened all the h/tmake-xxxx
706 to h/t-xxxx files so that everything will work on System V.
708 Fri Aug 23 13:51:06 1991 John Gilmore (gnu at cygint.cygnus.com)
710 * aoutx.h: Add information on host-aout.c and how to configure
711 to use it, to the manual.
712 * configure.in: Tix typo.
713 * ecoff.c: If compiling for DEC3100, use trad_unix core files,
714 else dummy out the core file support.
715 * trad-core.c (trad_unix_core_file_p): If HOST_DATA_START_ADDR is
716 specified, use it to locate the data section.
717 * coffcode.h (coff_write_symbols): Declare buffer as bfd_bytes

733 * trad-core.c (trad_unix_core_file_p): Use HOST_TEXT_START_ADDR,
734 etc, rather than TEXT_START_ADDR.
735 * host-aout.c: Remove #if 0 around whole thing.
736 Update to modern (32/64-bit) a.out naming conventions.
737 Include a large chunk of ../include/a.out.gnu.h to get macros that
738 are not defined by the system include files.
739 (host_aout_{32,64}_write_object_contents): Use the WRITE_HEADERS
740 macro used by the other a.out implementations.
741 * Makefile.in: Give dependencies to OPTIONAL_BACKENDS.
743 Wed Aug 21 14:33:06 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
745 * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of
746 texdoc and psdoc; make these depend on generated .texi's
748 * scanit, (new) unPROTO: turn PROTO macros into ANSI declarations in
751 * bfd.c, reloc.c, syms.c: minor spelling/wording fixes in doc
754 * Makefile.in, awkscan-ip, awkscan-p, intobfd,

795 Wed Jul 31 09:53:52 1991 John Gilmore (gnu at cygint.cygnus.com)
797 * all files: update copyright notices for GPL version 2.
798 Install header comments and attribute most modules to their
799 authors. BFD's name is now officially "Binary File Descriptor",
800 so remove any conflicting pejoratives.
801 archures.h: Consists solely of comments; remove it.
803 Fri Jul 26 18:11:34 1991 Steve Chamberlain (steve at cygint.cygnus.com)

819 29k coff by David Wood (wood@lab.ultra.nyu.edu).
821 Thu Jul 4 09:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
823 * Everything: created some new files, core.c format.c, reloc.c,
824 section.c and syms.c to split the functionality a bit better.
825 Cleaned up the rest of the files a bit, and added some
829 Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu)

834 Fri Jun 14 13:19:40 1991 Steve Chamberlain (steve at cygint.cygnus.com)
836 * ../include/bfd.h (struct bfd_target): Added new field
837 "align_power_min" which contains the minimum alignment for a
838 section. This is used in coff_new_section_hook. The field
839 insertion necessitates an update of all backends..
841 * aoutf1.h jump table field inserted
843 * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
846 * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
847 table field inserted.
849 * coffcode.h(just about everything) Now patches up symbol tables
850 using a different mechanism. The Intel major bug has been fixed,
851 and the linker can self host on the Aviion and be debugged with

871 * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
873 * srec.c: now allows any number of sections to be created in a
874 file. Outputs addresses of the right length.
876 Thu May 30 15:30:10 1991 Steve Chamberlain (steve at cygint.cygnus.com)
878 * bfd.c (bfd_check_format): Fixed problem where when a defaulted
879 target didn't match, the format got set to the attempted match,
880 breaking a future test.
882 *../include/i386coff.h : fixed typo in type field with size
884 * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
885 support in the jump table for the swapping routines exported to
886 gdb. Now gdb works with the 386.
888 Tue May 28 17:21:43 1991 John Gilmore (gnu at cygint.cygnus.com)
890 * Merge in changes from gdb-3.95 release.
891 Makefile.in: Allow hmake and tmake files to add OFILES.
893 bfd.c: support specific targets as well as searching. When
894 searching, take default target in preference to others.
896 ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
897 liba.out.h: Don't hard-code file offsets; use N_ macros for them.
898 libbfd.h: Support specific targets as well as searching.
899 opncls.c: Support specific targets as well as searching.
900 targets.c: Search is short-circuited if default target matches.
901 liboasys.c, libieee.c: Undo bothner changes that make macros
902 work to the left of assignment, but which depend on the
903 representations of different pointer types being the same.
905 Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
907 * i386coff.c: created.
908 * coffcode.h: added support for 386.

926 from which it was split out. Now 64 bit version is built with a
927 -DHOST_64_BIT="long long" on the compile line.
930 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
932 Changed all the [get|put][name] routines to use [get|put]_[size
935 Put in support for 64 bit work. Now two versions of bfd may be
936 generated, according to the state of TARGET_64_BIT, one which is
937 32 bit only, and one which is 64/32 bits.
938 Created new back end 'demo64' to test 64 bit functionality.
940 Renamed some files to work on DOS.
942 * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added

952 Added demo * aout32, aout64.c include aoutx.h * bout.c: used to
953 be called b.out.c * coffcode.h: used to be called coff-code.h, now
954 64bit ized. * demo64.c: 64 bit a.out back end
960 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
962 * libieee.h: Make ieee_data and ieee_ar_data macros usable
963 on LHS of assignment, even when using old compilers.
964 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
965 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
966 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
967 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
968 * targets.c: Add declaration of newsos3_vec.
971 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
973 * aout.c: fixxed some of the problems with filepos calculation.
974 (swap_ext_reloc): fixed problem with creation of relocs.
975 (aout_set_section_contents): fixed filepos problem
977 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
978 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
979 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
980 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
981 cleaned up. (coff_write_object_contents) cleaned up.
983 * ecoff.c: Totally different. Now supports ecoff fully.
985 * icoff.c: fixed problems in relocation callout.
987 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
989 * m68kcoff.c: updated target vector.
991 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
992 choose_reloc_size. (sunos4_write_object_contents) now calls
993 choose_reloc_size so outputs relocs correctly, also calculates the
994 size of the sections correctly.
998 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1000 Merge Per Bothner's changes to modularize BFD a.out a bit.
1002 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
1003 * ieee.c: Cast enums to int before comparing them, for brain-
1005 * coff-code.h: Remove coff_get_section_contents, and use the
1006 generic one instead.
1008 * aout.c: Derive new module from sunos.c, containing generic
1009 support code for all kinds of a.out files.
1011 * sunos.c: Remove all code that goes in aout.c. Split out
1012 machine dependent followup in sunos4_object_p into
1013 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
1014 and redefine only the names we CHANGE, not all the names. Drop
1015 the little-endian vector, and rename the vector as sunos4 rather
1018 * b.out.c: Use aout.c routines for most of the work. Slight
1019 changes for the new regime. Remove close_and_cleanup and
1020 get_section_contents in favor of generics. New transfer vector
1023 * newsos.c: New support for Sony NEWS, another a.out format.
1025 * ecoff.c: Remove close_and_cleanup. New tvec regime.
1026 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
1027 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
1029 * opncls.c (bfd_close): Call format-dependent write_contents
1030 routine, if writing, before calling target-dependent
1031 close_and_cleanup routine (which is now always generic, I think).
1032 * srec.c: Use bfd_alloc instead of malloc. Remove
1033 close_and_cleanup and move code from it to
1034 srec_write_object_contents. Add write_contents to tvec.
1035 * targets.c: Remove a.out little vector, replace a.out big
1036 vector with SunOS vector. FIXME: Need Vax support again now.
1038 * libbfd.h: Add write_contents format-dependent-vector to the
1039 bfd_target vector. Supply a generic close_and_cleanup routine.
1040 * liba.out.h: Handle the new aout.c split. Add prototypes for
1041 all routines defined in aout.c. Rename "sunos" things to "aout"
1042 things. Add a few fields where needed for various formats.
1043 * Makefile.in: Add aout.c and newsos.c.
1045 * archive.c, ieee.c, oasys.c: Lint.
1047 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1050 changed forward declaration struct stat; to reduce warnings. Changed
1051 comment on bfd_h_<x>_x.
1053 * ../include/m68kcoff.h, ../include/intel-coff.h,
1054 ../include/m88k-bcs.h
1055 Now there are two incarnations of relocs, linenos and syments. One for
1056 internal digestion, and one full of char arrays for I/O. The original
1057 names have gone to detect errors.
1059 * Makefile.in, m68kcoff.c, targets.c
1060 Test new structure code with a 68k coff implementaion
1062 * coff-code.h, icoff.c, coffswap.c, libcoff.h
1063 Fixed all the places where there were problems with the size and
1064 alignments of structures on disk and structures in memory. #ifed out
1065 all the code in coffswap.c, since it should be done using the target
1068 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1070 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
1071 multiple reloc command.
1073 * sunos.c (sunos4_set_section_contents): Made it so that sections
1074 are always padded to their alignment size.
1076 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1078 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
1079 Clean up types and such (saber C problems).
1080 * ecoff.c: Clean up types and such. Remove routines that are
1081 not used. Fix up reading and swapping of shorts from files.
1083 Notes on bfd-0.5.2-patch1a, from Per Bothner:
1085 * a.out.vax.c: Remove two bogus "static" from prototypes.
1087 * ecoff.c: Got rid of lots of non-working junk (that had
1088 been copied directly from coff-code.h).
1089 Updated to be consistent with updates to icoff.c and coff-code.h.
1091 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
1092 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
1094 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
1095 but until the target_vector is automatically generated,
1096 it's as good as any. Note that the text offset is the only
1097 difference between NewsOS and SunOs (including magic numbers).
1098 (Most of the sunos_* routines should to renamed bsd_*
1099 and move to a bsd.c file. Then (and when the target_vector
1100 is automatically generated) it might make sense to create
1101 a separate Sony target.)
1103 * sysdep.h: Don't declare fread and fwrite. Causes trouble
1104 on some systems, and doesn't help on others.
1105 Similarly, only define X_OK if not already defined.
1107 * trad-core.c: Don't include sys/stat.h - at least
1108 on NewsOS 3, it has already been included.
1110 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1112 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
1113 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
1114 symbol tables if necessary when reading them in, so gdb can use
1115 them. Add "bfd_coff_" to the names so they won't conflict with
1116 names in calling programs. FIXME-soon: if coff-code.h is
1117 included in two BFD modules, this will cause duplicate
1118 definitions; the routines should be exported to a separate,
1119 common, module (probably along with a mess of other ones).
1121 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1123 Improve modtime support.
1125 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
1126 Remove #define for bfd_get_mtime. Remove gratuitous comment.
1127 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
1128 BUG: archive members still do not get correct mod times.
1130 Improve floating point support for core files.
1132 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
1133 (sunos4_core_file_p): Create a second registers section in the
1134 core file, called ".reg2", for the float registers.
1136 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1138 * many changes to improve archive handling; found a logic flaw in
1139 bfd_check_format which only just happened to work by cooncidence.
1141 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1143 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
1146 * bfd.h: changed type of udata in asymbol to void *, like it
1147 should be. Added bfd_reloc_dangerous enum member.
1149 * coff-code.h: Fixed it so that internally generated symbols get
1150 their values relocated correctly in all cases. Removed calls to
1153 * icoff.c: Not understanding the destination symbol of a reloc is
1154 not a failure any more, just 'dangerous'. This allows linking of
1155 b.out and coff images.
1157 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
1161 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1163 * sunos.c (translate_to_native_sym_flags): fixed
1164 sym_pointer->n_value so that symbols on the way out get their
1165 section relative values calculated correctly.
1167 * coff-code.h (mangle_symbols): fixed problem where tags were not
1168 being relocated for structs, enums, unions. Also various lints.
1170 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1172 * archive.c (get_elt_at_filepos): system_call_error returned
1175 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1177 * Resolve the use of no_error and system_call_error.
1178 The bfd library itself now will never set bfd_error to
1181 The code still needs to be combed to make sure all the error
1182 codes are correct. I suspect they are not always set correctly.
1184 * The names of all the messages have _ prepended because the sun
1185 bundled compiler can't distinguish from a macro which takes an
1186 argument and the same identifier in a non-macro context.
1188 * The reason for the above being that entry points which used to
1189 be trampoline functions are now just macros which expand to a
1190 direct call through the bfd's xfer vector.
1192 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
1193 must gas have its own version of everything (the gas version
1194 had the correct value)
1196 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1198 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
1199 properly support i960 architecture and output correct reloc stuff.
1201 * bfd.h: added prototype for bfd_printable_arch_mach, added
1204 * coff-code.h: Applied patches from chrisb to support i960
1205 architecture, zero relocs and swap them correcly and conditionally
1206 compiled the timestamp.
1208 * sunos.c: Made the default section alignment 2^3 so that doubles
1209 are done properly. Fixed the same reloc bug that was in b.out.c
1211 * sysdep.h: Now compiles on a Posix box
1213 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1215 * icoff.c: Fix comment on big-endian version.
1216 * coff-code.h: Make HAS_RELOC really work (it's backwards from
1217 F_RELFLG). Set F_AR32WR in output files if little endian
1220 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
1222 * archures.c fixed =/== typo
1224 * sunos.c added architecture stuff for output. Fixed
1225 bug where files where vma(data) != size(text)
1226 were processed wrong.
1228 * coff-code.h added a lint cast
1230 * (../include/a.out.sun4.h) fixed it so zmagic
1233 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
1235 * archive.c removed loads of includes, and fixed bug where string
1236 table didn't have a null at the end.
1238 * bfd.c fixed includes, added symbols argument to
1239 canonicalize_reloc entry point.
1241 * libbfd.c fixed includes and added some lint patches.
1243 * targets.c added both sorts of intel coff.
1245 * b.out.c fixed included, changed was the canonical
1248 * icoff.c added support for callj and big and little
1251 * opncls.c added chmod+xing for files with EXEC_P set.
1253 * sunos.c fixed includes. Changed default section
1254 alignement to words. Fixed relocation stuff to work with
1257 * bfd.h various new types added, prototype for new
1258 reloc calls, changed bfd->iostream to a void *
1259 to including files don't need stdio.h.
1261 * libcoff.h added conversion table to tie relocs to
1266 * coff-code.h fixed includes. Added code to support
1267 big and little endian formats. Various lints. Better
1268 processing of symbols. Changed reloc stuff to new
1271 * libbfd.h fixed includes
1274 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
1276 * bfd.h changed name of alignment entry in sec_struct to
1277 alignment_power, because of conflicting uses within bfd.
1278 Now it should be obvious that it's a 2**n alignment
1279 specifier. Removed start_pad, end_alignment, block, minsize,
1280 output_file_alignment, subsection_alignment and original_vma fields.
1281 Added align_power() macro. Fixed bfd_section_alignment
1282 acessor macros. Added bfd_symbol_same_target macro.
1284 * b.out.c (b_out_write_object_contents) fixed to use
1285 new alignment member. Fixed (callj_callback) to use section
1286 relative symbols properly.
1288 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
1289 Fixed (translate_from_native_sym_flags) to correctly make
1290 symbols section relative.
1292 * bfd.c (bfd_errmsg) fixed various enum cast problems.
1293 (bfd_make_section) took out initialization of obsolete members.
1294 (bfd_print_symbol_vandf) added
1296 * opncls.c (bfd_create) created.
1298 * coff-code.h (coff_new_section_hook) took away refs
1299 to obsolete members. (make_a_section_from_file) added
1300 conversion between alignment types. (coff_symbol_from)
1301 added. (coff_count_linenumbers) only counts linenumbers
1302 if symbol is of coff-type. (coff_mangle_symbols) only
1303 heavily mangles symbols if symbol is coff-type.
1304 (coff_write_symbols) various lints. (coff_write_object_contents)
1305 various lints and modification for alignment conversion.
1306 (coff_slurp_relocs) fixed for use with new asection shape.
1308 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
1310 * archive.c lots of lint
1312 * b.out.c added callj relocation support, upgrated reloc howto.
1313 Fixed so that asymbol and reloc records are output
1316 * bfd.c lots of lint, support for new bfd entry point
1319 * bfd.h changed definition of asymbol to contain pointer to
1320 owning bfd, removed target dependencies.
1322 * cache.c took out print statements, put in BFD_ASSERT calls.
1324 * coff-code.h various lints, corrected linenumber output
1325 functionality. Added support for new style asymbols and
1326 bfd_print_symbol. Fixed so that asymbol and
1327 reloc records are handled correctly. Added timestamp.
1329 * icoff.c Added support for new howto shape.
1331 * liba.out.h Added support for new asymbol shape
1333 * libbfd.c various lints
1335 * libbfd.h various lints
1337 * libcoff.h added support for new asymbol shape.
1339 * sunos.c various lints. Added support for new asymbol shape
1340 and bfd_print_symbol.
1342 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
1344 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
1345 pointer lint. Added support for callj relocation. Fixed bug where
1346 the last 32 bytes of the text section were overwritten by data. Fixed bug
1347 where archives of b.out didn't work due bfd_slurp_extended_name_table
1350 * sunos.c added support for n_other field. Braced the howto table so
1351 that it won't be affected by any lengthing of the howto struct typedef.
1354 * bfd.h added support for n_other field, added special_function
1355 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x

1360 Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl)
1362 * ChangeLog: Started ChangeLog for BFD.
1363 * ToDo: Create file for suggestions.
1365 * Makefile: Support easy loading into Saber C.
1366 Add dependencies for icoff.o and bcs88kcoff.o.
1367 Rename coff.c to coff-code.h. Change callers.
1369 * bfd.c (bfd_check_format): Allow the check_format routines
1370 to return the desired target vector, rather than just a Boolean.
1371 bfd.h (bfd_check_format): Change function pointer return type.
1372 archive.c (bfd_generic_archive_p): change callee.
1373 b.out.c (b_out_little_object_p, b_out_big_object_p,
1374 b_out_real_object_p): change callee.
1375 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
1376 in check_format transfer vectors that need a filler.
1377 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
1378 bcs88kcoff.c: change callee.
1379 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
1380 icoff.c: change callee.
1381 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
1383 * libbfd.c (zalloc): It should actually zero the storage!
1384 This was commented out for some reason.
1386 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
1387 This is so callers can avoid <stdlib.h> which doesn't exist
1390 * bfd.c (map_over_sections): Add debugging code, since I
1391 noticed the section count for sunos core files was bad, but only
1392 GDB had detected the problem.
1393 (bfd_set_section_lineno_size, bfd_set_section_linenos,
1394 bfd_get_section_linenos): Remove obsolete functions.
1395 (bfd_apply_relocations): Use longs, not ints, for the math.
1397 * bfd.h: Declare enum boolean and struct bfd_target as well
1398 as typedefs for them. Remove obsolete
1399 bfd_get_section_lineno_size.
1401 * cache.c: Make the "fdopen" support work. Keep better track
1402 of how many files are open. Centralize the opening of files
1403 and be sure bfd_open[rw] actually try to open the file. Evade
1404 linked list initialization problems.
1406 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
1408 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
1410 * cplus-dem.c: Delete file, since it is not part of BFD.
1412 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
1413 (bfd_openr, bfd_openw): Actually open the file, give error now.
1415 * sunos.c (sunos4_core_file_p): Set section count.
1416 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
1417 obsolete definitions.
1418 (_write_symbol_table): Initialize <idx> counter.
1419 (foop): Eliminate debugging code.
