1 Thu Nov 21 19:56:40 1991 Per Bothner (bothner at cygnus.com)
3 * stab-syms.c, syms.c: Moved bfd_stab_name() and bfd_stab_names[]
4 from syms.c to new file stab-syms.c. Also, since GNU extended
5 type codes such as N_SETT are no longer in ../include/stab.def,
7 * stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
8 bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
9 * libaout.h: Added prototype for aout_stab_name().
10 * Makefile.in: Update Makefile for new stab-syms.[co].
12 Thu Nov 21 11:50:49 1991 John Gilmore (gnu at cygnus.com)
14 * libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this
15 rather complicated seeming problem. Eliminate LOGICAL_ versions,
16 just make N_XXX work by excluding the header from the text segment.
17 * aoutx.h: Fix comments to match.
19 Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
21 * libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
22 LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
23 for the "logical" text segment (i.e. never consider the exec
24 header to be part of the text segment). This change is
25 needed for consistency with various other parts of bfd and ld.
26 * aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
27 and move calculation of obj_textsec(abfd)->size to libaout.h.
28 * bfd-in.h: Removed bogus ';'.
30 * Makefile.in: Add MINIMIZE flag to select lean
31 or bloated target_vector.
32 * targets.c: Use new MINIMIZE macro, and add trad_core if needed.
33 * newsos3.c: Fixes to ../include/aout64.h remove need
34 for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
36 Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
38 * aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h
39 handle both little and big-endian targets, with little
40 the default unless TARGET_IS_BIG_ENDIAN_P is defined.
41 * host-aout.c: Add FIXME note.
43 Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
45 * targets.c: Make the default target_vector contain
46 just &DEFAULT_VECTOR. This makes executables a lot smaller.
47 Old behavior can be gotten by defining ALL_TARGETS.
48 * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
49 Factored out common code into new file aout-target.h.
50 Saves a lot of duplicate code for a.out variants.
52 Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)
54 Get 'make headers' to work when configured with +subdirs.
55 * Makefile.in: Add $(subdir) to docdir path.
56 * doc/Makefile.in (protos): Add $(srcdir) prefix
57 to name of sed scripts.
59 Thu Nov 14 19:49:10 1991 Per Bothner (bothner at cygnus.com)
61 * aoutx.h (NAME(aout,print_symbol)): Fix thinko.
62 * syms.c (bfd_stab_names): Turn on new GNU_EXTRA_STABS macro
63 to include names of N_SETT etc.
65 Thu Nov 14 19:11:13 1991 Fred Fish (fnf at cygnus.com)
67 * elf.c: Add minimal support for ELF symbol tables. Generates
68 canonical bfd symbol tables from ELF symbol tables. Change the
69 name of some functions from bfd_<name> to elf_<name>.
71 * syms.c: Trivial fix to comment to remove a redundant "to".
73 Wed Nov 13 17:02:01 1991 John Gilmore (gnu at cygnus.com)
75 * coff-{i386,m68k,m88k}.c: Change name of file format to standard
76 form that GDB recognizes as COFF.
78 Wed Nov 13 09:09:41 1991 Steve Chamberlain (sac at cygnus.com)
80 * ieee.c (ieee_object_p): cast NULL correctly.
81 * configure.in: added harris host

85 Tue Nov 12 07:21:41 1991 John Gilmore (gnu at cygnus.com)
87 * coff-m88k.c (coff_write_armap): Just #undef it.
89 Mon Nov 11 20:30:18 1991 Steve Chamberlain (sac at cygnus.com)
91 * Makefile.in: standardize on MINUS_G to disable debugging
92 * coff-m88k.c: create coff armaps instead of bsd ones.
93 * opncls.c (bfd_close_all_done), (bfd_close): Mask out random bits
96 Mon Nov 11 19:07:32 1991 Fred Fish (fnf at cygnus.com)
98 * elf.c: Additions to support ELF format core files.
99 * config/mh-amix: Add -DHAVE_PROCFS to HDEFINES, since host
100 has support for /proc (all the include files in particular).
102 Mon Nov 11 18:36:47 1991 Per Bothner (bothner at cygnus.com)
104 * aoutx.h (NAME(aout,find_nearest_line)): Handle the case
105 of two N_SO stabs, one for directory, and one for filename.
107 * bfd-in.h (print_vma): Factor out duplicate definition.
109 Exit a little more gracefully when malloc returns NULL.
110 * libbfd.c: New function bfd_xmalloc (malloc wrapper).
111 * opncls.c, syms.c, bout.c, aoutx.h: Replace malloc by bfd_xmalloc.
112 * libbfd.h: Rre-generated due to libbfd.c update.
114 Sat Nov 9 13:45:01 1991 Fred Fish (fnf at cygnus.com)
116 * config/mt-m68k-elf: Define DEFAULT_VECTOR as elf_big_vec.
118 * elf.c (elf_object_p): Don't try to create a bfd section for
119 the first ELF section header. It is just a placeholder.
121 Sat Nov 9 03:04:26 1991 John Gilmore (gnu at cygnus.com)
123 * coff-rs6000.c, config/mh-rs6000: Make it work on archive and
124 core files, when compiling native.
125 * hosts/h-rs6000.h: Define FASCIST_FDOPEN for bfd_fdopenr.
127 FIXME: The aoutf1.h change below needs to be reversed back
130 Thu Nov 7 11:03:55 1991 Steve Chamberlain (sac at rtl.cygnus.com)
132 * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
133 manipulation of lnno fields in lineno structs in a coff-<f>.h
134 independent way. Override it in coff-<f>.h to your favourite
135 number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
136 (coff_swap_lineno_out): modified to use the new macros.
138 Mon Nov 4 11:38:33 1991 Steve Chamberlain (sac at cygnus.com)
140 * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
141 unknown arch when the magic number doesn't specify the
142 architecture, since some OSs (eg old sun3s) don't set the number, and
143 020 is probably the right answer anyway.
145 Sun Nov 3 12:07:08 1991 Per Bothner (bothner at cygnus.com)
147 * hosts/h-news.h, hosts/h-rtbsd.h:
148 Get rid of MISSING_VFPRINTF, since libiberty provides one.
149 * bfd-in.h (bfd_print_symbol_type_hopw enum): Add new option
150 bfd_print_symbol_nm, for use by nm.
151 * aoutx.h (NAME(aout,print_symbol)): Add code for new
152 bfd_print_symbol_nm option, to print in nm format.
153 * coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
154 oasys.c (oasys_print_symbol): Provide stub implementations
155 for bfd_print_symbol_nm.
156 * syms.c: New function bfd_decode_symclass, used by nm printer.
157 New function bfd_stab_name to look up string name of stab code.
159 Sat Nov 2 14:26:03 1991 Steve Chamberlain (steve at cygnus.com)
161 * Makefile.in: Added ctor.c
162 * archures.c (bfd_default_arch_struct) added
163 bfd_default_reloc_type_lookup.
164 * coffcode.h: removed a load of #if 0ed code.
165 (coff_compute_file_section_positions): now works out the section
166 alignment and size correctly in all cases.
167 (coff_get_symtab): looks for constructor symbols and calls the
168 right function when they're found. (coff_canonicalize_reloc):
169 knows when a section is full of constructors and does the right
171 * cpu-m88k.c: Added default_reloc_type lookup to the architecture
173 * libbfd-in.h: (bfd_default_reloc_type_lookup) defun added.
174 * libcoff.h: removed #if 0ed code
175 * reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
176 arch independent constructor relocation type.
177 (bfd_reloc_type_lookup): removed the comment "this will go away"
178 since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
179 reloc which is used when BFD_RELOC_CTOR falls through to give a
180 default 32bit reloc for constructors.
181 (bfd_default_reloc_type_lookup): added.
182 * aoutf1.h: fixed SEGMENT_SIZE typo.
184 Thu Oct 31 18:23:06 1991 John Gilmore (gnu at cygnus.com)
186 * coff-rs6000.c: Change name to "aixcoff-rs6000", to avoid
187 matching prefix "coff".
188 * coffcode.h (coff_swap_aux_in, coff_swap_aux_out): Handle
189 rs/6000 csect records.
191 Sun Oct 27 16:56:58 1991 Steve Chamberlain (steve at cygnus.com)
193 * coff-m88k.c, targets.c: change name of m88k_bcs to m88kbcs
194 * configure.in: add motorola delta88 cases
195 * libbfd.h, libbfd-in.h, archive.c, ieee.c, elf.c, srec.c: fix
196 write_armap prototype
197 * libbfd.c: add doc on bfd_write_bigendian_4byte_int
199 Fri Oct 25 02:48:19 1991 John Gilmore (gnu at cygnus.com)
201 * Rename COFF-related files in `coff-ARCH.c' form.
202 coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
203 coff-mips.c, coff-rs6000.c to be exact.
205 * Makefile.in: Only supply TARGET_DEFAULTS to targets.c, reducing
207 * config/mt-*: Ditto.
209 Thu Oct 24 22:40:07 1991 John Gilmore (gnu at cygnus.com)
211 RS/6000 support, by Metin G. Ozisik, Mimi Phûông-Thåo Võ, and
212 John Gilmore. Archive support from Damon A. Permezel.
214 * Makefile.in: Add cpu-rs6000.c and rs6000coff.c.
215 * configure.in: Add rs6000 case.

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

480 * reloc.c: Extended NEWHOWTO macro
481 * ieee.c: Changed the way 8bit pcrel is done
482 * cpu-h8300.c: got the registers in the right order
484 Thu Oct 3 19:39:55 1991 John Gilmore (gnu at cygnus.com)
486 * bfd-in.h: enum boolean => enum bfd_boolean for SVR4. Gumby's
487 prediction is vindicated!
489 * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
490 Remove refs to howto.c, since Steve forgot.
492 Thu Oct 3 07:49:21 1991 Steve Chamberlain (steve at cygnus.com)
494 * elf.c: took the abort out of set_arch_mach so that objdump -i will
495 still work. Now allows any architecture/machine to be set.
497 Wed Oct 2 13:50:35 1991 Steve Chamberlain (steve at cygnus.com)
499 * howto.c deleted and moved code to reloc.c
501 * libbfd.h, libbfd-in.h removed $id stuff for real
503 * cpu-h8300.c Made it match various different spellings of h8300.
505 * archures.c: Took out the first char filter which made it only
506 look for a cpu/arch match when the first chars of supplied and
507 tested names were the same.
509 * targets.c removed oasys stuff, pending someone to fix the bugs
513 Tue Oct 1 12:29:44 1991 John Gilmore (gnu at cygnus.com)
515 * Makefile.in, configure.in, targets.c, elf.c: Add preliminary
516 ELF support good enough for GDB.
517 * configure.in, config/h-amix, config/t-m68k-elf: Handle
518 m68k-cbm-svr4 host and target.
519 * config/t-m68k-coff, t-m88k-coff, t-m88k-aout: Make files nonempty
520 so `diff' and `patch' can cope.
522 Tue Oct 1 11:24:31 1991 Steve Chamberlain (steve at cygnus.com)
524 * archures.c: removed texinfo error
526 * init.c: added texinfo hooks, and removed initialization error
529 * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
532 Tue Oct 1 05:02:53 1991 John Gilmore (gnu at cygnus.com)
534 * cpu-i960.c: Avoid numerical count of initializers.
536 Vax Ultrix changes from David Taylor <taylor@think.com>:
537 * host-aout.c: Make little-endian vector really little-endian.
538 * configure.in: Separate vax and tahoe cases, handle ultrix.
539 * config/t-vax: Add trad-core.o.
540 * config/h-vaxult: New host system.
542 Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
544 * bfd-in.h VERSION, change version number to 0.18, this makes a
545 gap, but now is the same as the linker version number.
547 * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
548 cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
549 files will eventually contain processor specific bits for bfd,
550 like strange relocation information and dis/assembly. So far only
551 the H8 has been even partially done. This work also ties in with
552 the change in handling architectures.
554 * amdcoff.c: (a29k_reloc) fix error message.
556 * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
557 discover the architecture of the bfd. (sunos4_callback) calls the
558 function bfd_set_arch_mach rather than stuffing stuff directly
559 into the bfd. (sunos4_write_object_contents), changed names of
562 * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
563 setup the environment.
565 * archive.c: (bfd_slurp_coff_armap) coff archives always have the
566 headers in big endian format, regardless of the endianess of the
569 * archures.c: totally changed. Now an architecture is represented
570 with a pointer to an info structure rather than an enumerated type
571 and a long. The old info is available as two elements in the
572 structure. Future enhancements to architecure support will
573 involve pointers to methods being placed into the info structure.
575 * bfd.c: changed the definition of the bfd structure for the new
578 * bout.c: (b_out_set_arch_mach) changed to use the new
579 architecture mechanism.
581 * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
582 the new architecture mechanism.
584 * configure.in: added h8 stuff.
586 * ieee.c: too many changes to note. Now ieee files written with
587 bfd gas and ld can be read by gld and ieee only linkers and
590 * libbfd.c, libbfd.h: changed prototype of bfd_write.
592 * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
593 than fixing the structure directly.
595 * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
596 than fixing the structure directly.
598 * opncls.c: (new_bfd) makes sure that bfd_init has been called
599 before opening a bfd.
601 * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
602 rather than fixing the structure directly.
604 * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
605 in the t/hmake file) a user can select which backends they want
606 linked with bfd without changing the source.
608 * init.c: new, looks after initializing modules.
610 * howto.c: for future use, will allow an application to work out
611 what cookie to use as a handle on a relcoatio howto.
613 Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
615 * srec.c: Better error checking, partly from Peter Schauer.
616 (srec_object_p): Avoid assuming any file that starts with 'S' is
617 an S-record file! (Check for 3 uppercase-hex digits after it.)
618 (ISHEX): Define new macro for checking supposedly hex characters.
619 (pass_over): Treat as EOF any S-record line that:
620 * doesn't have hex in either size character
621 * produces a size larger than 0x7F
622 * has an unrecognized type number
624 Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
626 * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
627 opncls.c: Lint (saber actually).
629 Thu Sep 26 11:24:24 1991 Per Bothner (bothner at cygnus.com)
631 * libaout.h (WRITE_HEADERS): Set header's a_text field always.
632 * newsos3.c: Fixed two types: newos3 -> newsos3.
633 * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
634 to use correct segment.
636 Mon Sep 23 18:24:34 1991 Per Bothner (bothner at cygnus.com)
638 * aoutx.h (print_symbol): Handle missing symbol->name.
640 Fri Sep 20 12:26:01 1991 Stu Grossman (grossman at cygnus.com)
642 * aoutf1.h (swapcore_sparc): Change name of USRSTACK, fix comment
645 Tue Sep 17 17:23:49 1991 Stu Grossman (grossman at cygnus.com)
647 * oasys.c, configure.in, config/h-irix3, config/t-irix3:
648 add sgi/irix support.
650 Thu Sep 12 14:29:09 1991 John Gilmore (gnu at cygint.cygnus.com)
652 Changes for the AMD 29000 Ultracomputer port from David Wood.
655 * opncls.c (bfd_fdopenr): Handle NO_FCNTL.
657 * Makefile.in: Make subdirs work by using $(INCDIR) in the
660 * coffcode.h (coff_real_object_p): Pass information about the
661 current file's coff symbol format to BFD via the coff_data struct.
662 (coff_find_nearest_line): obj_icof => coff_data.
663 (coff_swap_sym_{in,out}): Check that SYMNMLEN == E_SYMNMLEN.
664 (coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
665 and DIMNUM == E_DIMNUM.
666 * configure.in: Handle a29k-*-* hosts, and targets
667 a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
668 * libcoff-in.h: Add local_n_btmask, local_n_btshft,
669 local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
670 local_linesz to `coff_data' (tdata) struct.
671 (coff_data, coff_data_type, coff_tdata): Rename struct icofdata.
672 * config/h-ultra3: Handle a29k-*-* hosts as Ultracomputers.
674 Thu Sep 12 14:07:22 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
676 * Makefile.in: $(MAKE) for make, $(docdir) for doc
677 * doc/Makefile: redundant dependencies for Sun-make VPATH bug
679 Tue Sep 10 20:34:12 1991 John Gilmore (gnu at cygint.cygnus.com)
681 * aoutf1.h (sunos4_core_file_p): Release the right storage in

694 abfd->direction and complain if erroneous.
696 * Makefile.in: Add crude dependencies.
698 Tue Sep 3 13:46:19 1991 Steve Chamberlain (steve at cygint.cygnus.com)
700 * config/* aoutx.h configure* shortened all the h/tmake-xxxx
701 to h/t-xxxx files so that everything will work on System V.
703 Fri Aug 23 13:51:06 1991 John Gilmore (gnu at cygint.cygnus.com)
705 * aoutx.h: Add information on host-aout.c and how to configure
706 to use it, to the manual.
707 * configure.in: Tix typo.
708 * ecoff.c: If compiling for DEC3100, use trad_unix core files,
709 else dummy out the core file support.

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

792 * all files: update copyright notices for GPL version 2.
793 Install header comments and attribute most modules to their
794 authors. BFD's name is now officially "Binary File Descriptor",
795 so remove any conflicting pejoratives.
796 archures.h: Consists solely of comments; remove it.
798 Fri Jul 26 18:11:34 1991 Steve Chamberlain (steve at cygint.cygnus.com)

814 29k coff by David Wood (wood@lab.ultra.nyu.edu).
816 Thu Jul 4 09:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
818 * Everything: created some new files, core.c format.c, reloc.c,
819 section.c and syms.c to split the functionality a bit better.
820 Cleaned up the rest of the files a bit, and added some
824 Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu)

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

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

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

948 be called b.out.c * coffcode.h: used to be called coff-code.h, now
949 64bit ized. * demo64.c: 64 bit a.out back end
955 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
957 * libieee.h: Make ieee_data and ieee_ar_data macros usable
958 on LHS of assignment, even when using old compilers.
959 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
960 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
961 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
962 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
963 * targets.c: Add declaration of newsos3_vec.
966 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
968 * aout.c: fixxed some of the problems with filepos calculation.
969 (swap_ext_reloc): fixed problem with creation of relocs.
970 (aout_set_section_contents): fixed filepos problem
972 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
973 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
974 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
975 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
976 cleaned up. (coff_write_object_contents) cleaned up.
978 * ecoff.c: Totally different. Now supports ecoff fully.
980 * icoff.c: fixed problems in relocation callout.
982 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
984 * m68kcoff.c: updated target vector.
986 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
987 choose_reloc_size. (sunos4_write_object_contents) now calls
988 choose_reloc_size so outputs relocs correctly, also calculates the
989 size of the sections correctly.
993 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
995 Merge Per Bothner's changes to modularize BFD a.out a bit.
997 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
998 * ieee.c: Cast enums to int before comparing them, for brain-
1000 * coff-code.h: Remove coff_get_section_contents, and use the
1001 generic one instead.
1003 * aout.c: Derive new module from sunos.c, containing generic
1004 support code for all kinds of a.out files.
1006 * sunos.c: Remove all code that goes in aout.c. Split out
1007 machine dependent followup in sunos4_object_p into
1008 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
1009 and redefine only the names we CHANGE, not all the names. Drop
1010 the little-endian vector, and rename the vector as sunos4 rather
1013 * b.out.c: Use aout.c routines for most of the work. Slight
1014 changes for the new regime. Remove close_and_cleanup and
1015 get_section_contents in favor of generics. New transfer vector
1018 * newsos.c: New support for Sony NEWS, another a.out format.
1020 * ecoff.c: Remove close_and_cleanup. New tvec regime.
1021 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
1022 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
1024 * opncls.c (bfd_close): Call format-dependent write_contents
1025 routine, if writing, before calling target-dependent
1026 close_and_cleanup routine (which is now always generic, I think).
1027 * srec.c: Use bfd_alloc instead of malloc. Remove
1028 close_and_cleanup and move code from it to
1029 srec_write_object_contents. Add write_contents to tvec.
1030 * targets.c: Remove a.out little vector, replace a.out big
1031 vector with SunOS vector. FIXME: Need Vax support again now.
1033 * libbfd.h: Add write_contents format-dependent-vector to the
1034 bfd_target vector. Supply a generic close_and_cleanup routine.
1035 * liba.out.h: Handle the new aout.c split. Add prototypes for
1036 all routines defined in aout.c. Rename "sunos" things to "aout"
1037 things. Add a few fields where needed for various formats.
1038 * Makefile.in: Add aout.c and newsos.c.
1040 * archive.c, ieee.c, oasys.c: Lint.
1042 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1045 changed forward declaration struct stat; to reduce warnings. Changed
1046 comment on bfd_h_<x>_x.
1048 * ../include/m68kcoff.h, ../include/intel-coff.h,
1049 ../include/m88k-bcs.h
1050 Now there are two incarnations of relocs, linenos and syments. One for
1051 internal digestion, and one full of char arrays for I/O. The original
1052 names have gone to detect errors.
1054 * Makefile.in, m68kcoff.c, targets.c
1055 Test new structure code with a 68k coff implementaion
1057 * coff-code.h, icoff.c, coffswap.c, libcoff.h
1058 Fixed all the places where there were problems with the size and
1059 alignments of structures on disk and structures in memory. #ifed out
1060 all the code in coffswap.c, since it should be done using the target
1063 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1065 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
1066 multiple reloc command.
1068 * sunos.c (sunos4_set_section_contents): Made it so that sections
1069 are always padded to their alignment size.
1071 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1073 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
1074 Clean up types and such (saber C problems).
1075 * ecoff.c: Clean up types and such. Remove routines that are
1076 not used. Fix up reading and swapping of shorts from files.
1078 Notes on bfd-0.5.2-patch1a, from Per Bothner:
1080 * a.out.vax.c: Remove two bogus "static" from prototypes.
1082 * ecoff.c: Got rid of lots of non-working junk (that had
1083 been copied directly from coff-code.h).
1084 Updated to be consistent with updates to icoff.c and coff-code.h.
1086 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
1087 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
1089 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
1090 but until the target_vector is automatically generated,
1091 it's as good as any. Note that the text offset is the only
1092 difference between NewsOS and SunOs (including magic numbers).
1093 (Most of the sunos_* routines should to renamed bsd_*
1094 and move to a bsd.c file. Then (and when the target_vector
1095 is automatically generated) it might make sense to create
1096 a separate Sony target.)
1098 * sysdep.h: Don't declare fread and fwrite. Causes trouble
1099 on some systems, and doesn't help on others.
1100 Similarly, only define X_OK if not already defined.
1102 * trad-core.c: Don't include sys/stat.h - at least
1103 on NewsOS 3, it has already been included.
1105 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1107 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
1108 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
1109 symbol tables if necessary when reading them in, so gdb can use
1110 them. Add "bfd_coff_" to the names so they won't conflict with
1111 names in calling programs. FIXME-soon: if coff-code.h is
1112 included in two BFD modules, this will cause duplicate
1113 definitions; the routines should be exported to a separate,
1114 common, module (probably along with a mess of other ones).
1116 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1118 Improve modtime support.
1120 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
1121 Remove #define for bfd_get_mtime. Remove gratuitous comment.
1122 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
1123 BUG: archive members still do not get correct mod times.
1125 Improve floating point support for core files.
1127 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
1128 (sunos4_core_file_p): Create a second registers section in the
1129 core file, called ".reg2", for the float registers.
1131 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1133 * many changes to improve archive handling; found a logic flaw in
1134 bfd_check_format which only just happened to work by cooncidence.
1136 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1138 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
1141 * bfd.h: changed type of udata in asymbol to void *, like it
1142 should be. Added bfd_reloc_dangerous enum member.
1144 * coff-code.h: Fixed it so that internally generated symbols get
1145 their values relocated correctly in all cases. Removed calls to
1148 * icoff.c: Not understanding the destination symbol of a reloc is
1149 not a failure any more, just 'dangerous'. This allows linking of
1150 b.out and coff images.
1152 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
1156 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1158 * sunos.c (translate_to_native_sym_flags): fixed
1159 sym_pointer->n_value so that symbols on the way out get their
1160 section relative values calculated correctly.
1162 * coff-code.h (mangle_symbols): fixed problem where tags were not
1163 being relocated for structs, enums, unions. Also various lints.
1165 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1167 * archive.c (get_elt_at_filepos): system_call_error returned
1170 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1172 * Resolve the use of no_error and system_call_error.
1173 The bfd library itself now will never set bfd_error to
1176 The code still needs to be combed to make sure all the error
1177 codes are correct. I suspect they are not always set correctly.
1179 * The names of all the messages have _ prepended because the sun
1180 bundled compiler can't distinguish from a macro which takes an
1181 argument and the same identifier in a non-macro context.
1183 * The reason for the above being that entry points which used to
1184 be trampoline functions are now just macros which expand to a
1185 direct call through the bfd's xfer vector.
1187 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
1188 must gas have its own version of everything (the gas version
1189 had the correct value)
1191 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1193 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
1194 properly support i960 architecture and output correct reloc stuff.
1196 * bfd.h: added prototype for bfd_printable_arch_mach, added
1199 * coff-code.h: Applied patches from chrisb to support i960
1200 architecture, zero relocs and swap them correcly and conditionally
1201 compiled the timestamp.
1203 * sunos.c: Made the default section alignment 2^3 so that doubles
1204 are done properly. Fixed the same reloc bug that was in b.out.c
1206 * sysdep.h: Now compiles on a Posix box
1208 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1210 * icoff.c: Fix comment on big-endian version.
1211 * coff-code.h: Make HAS_RELOC really work (it's backwards from
1212 F_RELFLG). Set F_AR32WR in output files if little endian
1215 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
1217 * archures.c fixed =/== typo
1219 * sunos.c added architecture stuff for output. Fixed
1220 bug where files where vma(data) != size(text)
1221 were processed wrong.
1223 * coff-code.h added a lint cast
1225 * (../include/a.out.sun4.h) fixed it so zmagic
1228 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
1230 * archive.c removed loads of includes, and fixed bug where string
1231 table didn't have a null at the end.
1233 * bfd.c fixed includes, added symbols argument to
1234 canonicalize_reloc entry point.
1236 * libbfd.c fixed includes and added some lint patches.
1238 * targets.c added both sorts of intel coff.
1240 * b.out.c fixed included, changed was the canonical
1243 * icoff.c added support for callj and big and little
1246 * opncls.c added chmod+xing for files with EXEC_P set.
1248 * sunos.c fixed includes. Changed default section
1249 alignement to words. Fixed relocation stuff to work with
1252 * bfd.h various new types added, prototype for new
1253 reloc calls, changed bfd->iostream to a void *
1254 to including files don't need stdio.h.
1256 * libcoff.h added conversion table to tie relocs to
1261 * coff-code.h fixed includes. Added code to support
1262 big and little endian formats. Various lints. Better
1263 processing of symbols. Changed reloc stuff to new
1266 * libbfd.h fixed includes
1269 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
1271 * bfd.h changed name of alignment entry in sec_struct to
1272 alignment_power, because of conflicting uses within bfd.
1273 Now it should be obvious that it's a 2**n alignment
1274 specifier. Removed start_pad, end_alignment, block, minsize,
1275 output_file_alignment, subsection_alignment and original_vma fields.
1276 Added align_power() macro. Fixed bfd_section_alignment
1277 acessor macros. Added bfd_symbol_same_target macro.
1279 * b.out.c (b_out_write_object_contents) fixed to use
1280 new alignment member. Fixed (callj_callback) to use section
1281 relative symbols properly.
1283 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
1284 Fixed (translate_from_native_sym_flags) to correctly make
1285 symbols section relative.
1287 * bfd.c (bfd_errmsg) fixed various enum cast problems.
1288 (bfd_make_section) took out initialization of obsolete members.
1289 (bfd_print_symbol_vandf) added
1291 * opncls.c (bfd_create) created.
1293 * coff-code.h (coff_new_section_hook) took away refs
1294 to obsolete members. (make_a_section_from_file) added
1295 conversion between alignment types. (coff_symbol_from)
1296 added. (coff_count_linenumbers) only counts linenumbers
1297 if symbol is of coff-type. (coff_mangle_symbols) only
1298 heavily mangles symbols if symbol is coff-type.
1299 (coff_write_symbols) various lints. (coff_write_object_contents)
1300 various lints and modification for alignment conversion.
1301 (coff_slurp_relocs) fixed for use with new asection shape.
1303 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
1305 * archive.c lots of lint
1307 * b.out.c added callj relocation support, upgrated reloc howto.
1308 Fixed so that asymbol and reloc records are output
1311 * bfd.c lots of lint, support for new bfd entry point
1314 * bfd.h changed definition of asymbol to contain pointer to
1315 owning bfd, removed target dependencies.
1317 * cache.c took out print statements, put in BFD_ASSERT calls.
1319 * coff-code.h various lints, corrected linenumber output
1320 functionality. Added support for new style asymbols and
1321 bfd_print_symbol. Fixed so that asymbol and
1322 reloc records are handled correctly. Added timestamp.
1324 * icoff.c Added support for new howto shape.
1326 * liba.out.h Added support for new asymbol shape
1328 * libbfd.c various lints
1330 * libbfd.h various lints
1332 * libcoff.h added support for new asymbol shape.
1334 * sunos.c various lints. Added support for new asymbol shape
1335 and bfd_print_symbol.
1337 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
1339 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
1340 pointer lint. Added support for callj relocation. Fixed bug where
1341 the last 32 bytes of the text section were overwritten by data. Fixed bug
1342 where archives of b.out didn't work due bfd_slurp_extended_name_table
1345 * sunos.c added support for n_other field. Braced the howto table so
1346 that it won't be affected by any lengthing of the howto struct typedef.
1349 * bfd.h added support for n_other field, added special_function
1350 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x

1355 Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl)
1357 * ChangeLog: Started ChangeLog for BFD.
1358 * ToDo: Create file for suggestions.
1360 * Makefile: Support easy loading into Saber C.
1361 Add dependencies for icoff.o and bcs88kcoff.o.
1362 Rename coff.c to coff-code.h. Change callers.
1364 * bfd.c (bfd_check_format): Allow the check_format routines
1365 to return the desired target vector, rather than just a Boolean.
1366 bfd.h (bfd_check_format): Change function pointer return type.
1367 archive.c (bfd_generic_archive_p): change callee.
1368 b.out.c (b_out_little_object_p, b_out_big_object_p,
1369 b_out_real_object_p): change callee.
1370 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
1371 in check_format transfer vectors that need a filler.
1372 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
1373 bcs88kcoff.c: change callee.
1374 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
1375 icoff.c: change callee.
1376 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
1378 * libbfd.c (zalloc): It should actually zero the storage!
1379 This was commented out for some reason.
1381 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
1382 This is so callers can avoid <stdlib.h> which doesn't exist
1385 * bfd.c (map_over_sections): Add debugging code, since I
1386 noticed the section count for sunos core files was bad, but only
1387 GDB had detected the problem.
1388 (bfd_set_section_lineno_size, bfd_set_section_linenos,
1389 bfd_get_section_linenos): Remove obsolete functions.
1390 (bfd_apply_relocations): Use longs, not ints, for the math.
1392 * bfd.h: Declare enum boolean and struct bfd_target as well
1393 as typedefs for them. Remove obsolete
1394 bfd_get_section_lineno_size.
1396 * cache.c: Make the "fdopen" support work. Keep better track
1397 of how many files are open. Centralize the opening of files
1398 and be sure bfd_open[rw] actually try to open the file. Evade
1399 linked list initialization problems.
1401 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
1403 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
1405 * cplus-dem.c: Delete file, since it is not part of BFD.
1407 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
1408 (bfd_openr, bfd_openw): Actually open the file, give error now.
1410 * sunos.c (sunos4_core_file_p): Set section count.
1411 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
1412 obsolete definitions.
1413 (_write_symbol_table): Initialize <idx> counter.
1414 (foop): Eliminate debugging code.
