1 Fri Nov 22 08:11:42 1991 John Gilmore (gnu at cygnus.com)
3 * aoutx.h (some_aout_object_p): Set the `executable' bit
4 if the entry point is contained in the text segment, even if the
5 text segment is at location 0.
7 * coff-mips.c, coffcode.h: Peter Schauer's patch to kludge in
8 nonstandard MIPS sections (.rdata, .sdata, etc).
10 * aoutx.h, bfd.c, coffcode.h, ieee.c, oasys.c, targets.c: CONST lint.
11 * libbfd-in.h, libbfd.h, aoutx.h, coffcode.h, elf.c, libaout.h:
12 Rename ALIGN to BFD_ALIGN to avoid conflict with BSD <sys/param.h>.
14 * host-aout.c, trad-core.c: Fix write_armap prototypes. Lint.
16 Thu Nov 21 19:56:40 1991 Per Bothner (bothner at cygnus.com)
18 * stab-syms.c, syms.c: Moved bfd_stab_name() and bfd_stab_names[]
19 from syms.c to new file stab-syms.c. Also, since GNU extended
20 type codes such as N_SETT are no longer in ../include/stab.def,
21 include them manually.
22 * stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
23 bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
24 * libaout.h: Added prototype for aout_stab_name().
25 * Makefile.in: Update Makefile for new stab-syms.[co].
27 Thu Nov 21 11:50:49 1991 John Gilmore (gnu at cygnus.com)
29 * libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this
30 rather complicated seeming problem. Eliminate LOGICAL_ versions,
31 just make N_XXX work by excluding the header from the text segment.
32 * aoutx.h: Fix comments to match.
34 Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
36 * libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
37 LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
38 for the "logical" text segment (i.e. never consider the exec
39 header to be part of the text segment). This change is
40 needed for consistency with various other parts of bfd and ld.
41 * aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
42 and move calculation of obj_textsec(abfd)->size to libaout.h.
43 * bfd-in.h: Removed bogus ';'.
45 * Makefile.in: Add MINIMIZE flag to select lean
46 or bloated target_vector.
47 * targets.c: Use new MINIMIZE macro, and add trad_core if needed.
48 * newsos3.c: Fixes to ../include/aout64.h remove need
49 for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
51 Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
53 * aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h
54 handle both little and big-endian targets, with little
55 the default unless TARGET_IS_BIG_ENDIAN_P is defined.
56 * host-aout.c: Add FIXME note.
58 Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
60 * targets.c: Make the default target_vector contain
61 just &DEFAULT_VECTOR. This makes executables a lot smaller.
62 Old behavior can be gotten by defining ALL_TARGETS.
63 * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
64 Factored out common code into new file aout-target.h.
65 Saves a lot of duplicate code for a.out variants.
67 Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)
69 Get 'make headers' to work when configured with +subdirs.
70 * Makefile.in: Add $(subdir) to docdir path.
71 * doc/Makefile.in (protos): Add $(srcdir) prefix
72 to name of sed scripts.
74 Thu Nov 14 19:49:10 1991 Per Bothner (bothner at cygnus.com)
76 * aoutx.h (NAME(aout,print_symbol)): Fix thinko.
77 * syms.c (bfd_stab_names): Turn on new GNU_EXTRA_STABS macro
78 to include names of N_SETT etc.
80 Thu Nov 14 19:11:13 1991 Fred Fish (fnf at cygnus.com)
82 * elf.c: Add minimal support for ELF symbol tables. Generates
83 canonical bfd symbol tables from ELF symbol tables. Change the
84 name of some functions from bfd_<name> to elf_<name>.
86 * syms.c: Trivial fix to comment to remove a redundant "to".
88 Wed Nov 13 17:02:01 1991 John Gilmore (gnu at cygnus.com)
90 * coff-{i386,m68k,m88k}.c: Change name of file format to standard
91 form that GDB recognizes as COFF.
93 Wed Nov 13 09:09:41 1991 Steve Chamberlain (sac at cygnus.com)
95 * ieee.c (ieee_object_p): cast NULL correctly.
96 * configure.in: added harris host

100 Tue Nov 12 07:21:41 1991 John Gilmore (gnu at cygnus.com)
102 * coff-m88k.c (coff_write_armap): Just #undef it.
104 Mon Nov 11 20:30:18 1991 Steve Chamberlain (sac at cygnus.com)
106 * Makefile.in: standardize on MINUS_G to disable debugging
107 * coff-m88k.c: create coff armaps instead of bsd ones.
108 * opncls.c (bfd_close_all_done), (bfd_close): Mask out random bits
111 Mon Nov 11 19:07:32 1991 Fred Fish (fnf at cygnus.com)
113 * elf.c: Additions to support ELF format core files.
114 * config/mh-amix: Add -DHAVE_PROCFS to HDEFINES, since host
115 has support for /proc (all the include files in particular).
117 Mon Nov 11 18:36:47 1991 Per Bothner (bothner at cygnus.com)
119 * aoutx.h (NAME(aout,find_nearest_line)): Handle the case
120 of two N_SO stabs, one for directory, and one for filename.
122 * bfd-in.h (print_vma): Factor out duplicate definition.
124 Exit a little more gracefully when malloc returns NULL.
125 * libbfd.c: New function bfd_xmalloc (malloc wrapper).
126 * opncls.c, syms.c, bout.c, aoutx.h: Replace malloc by bfd_xmalloc.
127 * libbfd.h: Rre-generated due to libbfd.c update.
129 Sat Nov 9 13:45:01 1991 Fred Fish (fnf at cygnus.com)
131 * config/mt-m68k-elf: Define DEFAULT_VECTOR as elf_big_vec.
133 * elf.c (elf_object_p): Don't try to create a bfd section for
134 the first ELF section header. It is just a placeholder.
136 Sat Nov 9 03:04:26 1991 John Gilmore (gnu at cygnus.com)
138 * coff-rs6000.c, config/mh-rs6000: Make it work on archive and
139 core files, when compiling native.
140 * hosts/h-rs6000.h: Define FASCIST_FDOPEN for bfd_fdopenr.
142 FIXME: The aoutf1.h change below needs to be reversed back
145 Thu Nov 7 11:03:55 1991 Steve Chamberlain (sac at rtl.cygnus.com)
147 * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
148 manipulation of lnno fields in lineno structs in a coff-<f>.h
149 independent way. Override it in coff-<f>.h to your favourite
150 number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
151 (coff_swap_lineno_out): modified to use the new macros.
153 Mon Nov 4 11:38:33 1991 Steve Chamberlain (sac at cygnus.com)
155 * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
156 unknown arch when the magic number doesn't specify the
157 architecture, since some OSs (eg old sun3s) don't set the number, and
158 020 is probably the right answer anyway.
160 Sun Nov 3 12:07:08 1991 Per Bothner (bothner at cygnus.com)
162 * hosts/h-news.h, hosts/h-rtbsd.h:
163 Get rid of MISSING_VFPRINTF, since libiberty provides one.
164 * bfd-in.h (bfd_print_symbol_type_hopw enum): Add new option
165 bfd_print_symbol_nm, for use by nm.
166 * aoutx.h (NAME(aout,print_symbol)): Add code for new
167 bfd_print_symbol_nm option, to print in nm format.
168 * coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
169 oasys.c (oasys_print_symbol): Provide stub implementations
170 for bfd_print_symbol_nm.
171 * syms.c: New function bfd_decode_symclass, used by nm printer.
172 New function bfd_stab_name to look up string name of stab code.
174 Sat Nov 2 14:26:03 1991 Steve Chamberlain (steve at cygnus.com)
176 * Makefile.in: Added ctor.c
177 * archures.c (bfd_default_arch_struct) added
178 bfd_default_reloc_type_lookup.
179 * coffcode.h: removed a load of #if 0ed code.
180 (coff_compute_file_section_positions): now works out the section
181 alignment and size correctly in all cases.
182 (coff_get_symtab): looks for constructor symbols and calls the
183 right function when they're found. (coff_canonicalize_reloc):
184 knows when a section is full of constructors and does the right
186 * cpu-m88k.c: Added default_reloc_type lookup to the architecture
188 * libbfd-in.h: (bfd_default_reloc_type_lookup) defun added.
189 * libcoff.h: removed #if 0ed code
190 * reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
191 arch independent constructor relocation type.
192 (bfd_reloc_type_lookup): removed the comment "this will go away"
193 since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
194 reloc which is used when BFD_RELOC_CTOR falls through to give a
195 default 32bit reloc for constructors.
196 (bfd_default_reloc_type_lookup): added.
197 * aoutf1.h: fixed SEGMENT_SIZE typo.
199 Thu Oct 31 18:23:06 1991 John Gilmore (gnu at cygnus.com)
201 * coff-rs6000.c: Change name to "aixcoff-rs6000", to avoid
202 matching prefix "coff".
203 * coffcode.h (coff_swap_aux_in, coff_swap_aux_out): Handle
204 rs/6000 csect records.
206 Sun Oct 27 16:56:58 1991 Steve Chamberlain (steve at cygnus.com)
208 * coff-m88k.c, targets.c: change name of m88k_bcs to m88kbcs
209 * configure.in: add motorola delta88 cases
210 * libbfd.h, libbfd-in.h, archive.c, ieee.c, elf.c, srec.c: fix
211 write_armap prototype
212 * libbfd.c: add doc on bfd_write_bigendian_4byte_int
214 Fri Oct 25 02:48:19 1991 John Gilmore (gnu at cygnus.com)
216 * Rename COFF-related files in `coff-ARCH.c' form.
217 coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
218 coff-mips.c, coff-rs6000.c to be exact.
220 * Makefile.in: Only supply TARGET_DEFAULTS to targets.c, reducing
222 * config/mt-*: Ditto.
224 Thu Oct 24 22:40:07 1991 John Gilmore (gnu at cygnus.com)
226 RS/6000 support, by Metin G. Ozisik, Mimi Phûông-Thåo Võ, and
227 John Gilmore. Archive support from Damon A. Permezel.
229 * Makefile.in: Add cpu-rs6000.c and rs6000coff.c.
230 * configure.in: Add rs6000 case.
231 * targets.c: Add rs6000 vector.

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

469 last byte of transfer, not first byte, is within the section.
471 * host-aout.c: Remove `BSD' archive support. Lint.
473 * archures.c: Rename `struct bfd_arch_info_struct' to `struct
474 bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
475 `bfd_arch_info_type'. All uses changed.
476 * reloc.c: Rename `bfd_reloc_status_enum_type' to
477 `bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
478 to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
479 it needs a better name.) All uses changed.
480 * targets.c: Rename `enum target_flavour_enum' to `enum
481 target_flavour', and remove the `_enum' from all of the enum
482 values themselves. All uses changed.

499 Thu Oct 3 19:39:55 1991 John Gilmore (gnu at cygnus.com)
501 * bfd-in.h: enum boolean => enum bfd_boolean for SVR4. Gumby's
502 prediction is vindicated!
504 * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
505 Remove refs to howto.c, since Steve forgot.
507 Thu Oct 3 07:49:21 1991 Steve Chamberlain (steve at cygnus.com)
509 * elf.c: took the abort out of set_arch_mach so that objdump -i will
510 still work. Now allows any architecture/machine to be set.
512 Wed Oct 2 13:50:35 1991 Steve Chamberlain (steve at cygnus.com)
514 * howto.c deleted and moved code to reloc.c
516 * libbfd.h, libbfd-in.h removed $id stuff for real
518 * cpu-h8300.c Made it match various different spellings of h8300.
520 * archures.c: Took out the first char filter which made it only
521 look for a cpu/arch match when the first chars of supplied and
522 tested names were the same.
524 * targets.c removed oasys stuff, pending someone to fix the bugs
528 Tue Oct 1 12:29:44 1991 John Gilmore (gnu at cygnus.com)
530 * Makefile.in, configure.in, targets.c, elf.c: Add preliminary
531 ELF support good enough for GDB.
532 * configure.in, config/h-amix, config/t-m68k-elf: Handle
533 m68k-cbm-svr4 host and target.
534 * config/t-m68k-coff, t-m88k-coff, t-m88k-aout: Make files nonempty
535 so `diff' and `patch' can cope.
537 Tue Oct 1 11:24:31 1991 Steve Chamberlain (steve at cygnus.com)
539 * archures.c: removed texinfo error
541 * init.c: added texinfo hooks, and removed initialization error
544 * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
547 Tue Oct 1 05:02:53 1991 John Gilmore (gnu at cygnus.com)
549 * cpu-i960.c: Avoid numerical count of initializers.
551 Vax Ultrix changes from David Taylor <taylor@think.com>:

557 Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
559 * bfd-in.h VERSION, change version number to 0.18, this makes a
560 gap, but now is the same as the linker version number.
562 * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
563 cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
564 files will eventually contain processor specific bits for bfd,
565 like strange relocation information and dis/assembly. So far only
566 the H8 has been even partially done. This work also ties in with
567 the change in handling architectures.
569 * amdcoff.c: (a29k_reloc) fix error message.
571 * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
572 discover the architecture of the bfd. (sunos4_callback) calls the
573 function bfd_set_arch_mach rather than stuffing stuff directly
574 into the bfd. (sunos4_write_object_contents), changed names of
577 * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
578 setup the environment.
580 * archive.c: (bfd_slurp_coff_armap) coff archives always have the
581 headers in big endian format, regardless of the endianess of the
584 * archures.c: totally changed. Now an architecture is represented
585 with a pointer to an info structure rather than an enumerated type
586 and a long. The old info is available as two elements in the
587 structure. Future enhancements to architecure support will
588 involve pointers to methods being placed into the info structure.
590 * bfd.c: changed the definition of the bfd structure for the new
593 * bout.c: (b_out_set_arch_mach) changed to use the new
594 architecture mechanism.
596 * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
597 the new architecture mechanism.
599 * configure.in: added h8 stuff.
601 * ieee.c: too many changes to note. Now ieee files written with
602 bfd gas and ld can be read by gld and ieee only linkers and
605 * libbfd.c, libbfd.h: changed prototype of bfd_write.
607 * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
608 than fixing the structure directly.
610 * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
611 than fixing the structure directly.
613 * opncls.c: (new_bfd) makes sure that bfd_init has been called
614 before opening a bfd.
616 * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
617 rather than fixing the structure directly.
619 * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
620 in the t/hmake file) a user can select which backends they want
621 linked with bfd without changing the source.
623 * init.c: new, looks after initializing modules.
625 * howto.c: for future use, will allow an application to work out
626 what cookie to use as a handle on a relcoatio howto.
628 Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
630 * srec.c: Better error checking, partly from Peter Schauer.
631 (srec_object_p): Avoid assuming any file that starts with 'S' is
632 an S-record file! (Check for 3 uppercase-hex digits after it.)
633 (ISHEX): Define new macro for checking supposedly hex characters.
634 (pass_over): Treat as EOF any S-record line that:
635 * doesn't have hex in either size character
636 * produces a size larger than 0x7F
637 * has an unrecognized type number
639 Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
641 * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
642 opncls.c: Lint (saber actually).
644 Thu Sep 26 11:24:24 1991 Per Bothner (bothner at cygnus.com)
646 * libaout.h (WRITE_HEADERS): Set header's a_text field always.
647 * newsos3.c: Fixed two types: newos3 -> newsos3.
648 * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
649 to use correct segment.
651 Mon Sep 23 18:24:34 1991 Per Bothner (bothner at cygnus.com)
653 * aoutx.h (print_symbol): Handle missing symbol->name.
655 Fri Sep 20 12:26:01 1991 Stu Grossman (grossman at cygnus.com)
657 * aoutf1.h (swapcore_sparc): Change name of USRSTACK, fix comment
660 Tue Sep 17 17:23:49 1991 Stu Grossman (grossman at cygnus.com)
662 * oasys.c, configure.in, config/h-irix3, config/t-irix3:
663 add sgi/irix support.
665 Thu Sep 12 14:29:09 1991 John Gilmore (gnu at cygint.cygnus.com)

670 * opncls.c (bfd_fdopenr): Handle NO_FCNTL.
672 * Makefile.in: Make subdirs work by using $(INCDIR) in the
675 * coffcode.h (coff_real_object_p): Pass information about the
676 current file's coff symbol format to BFD via the coff_data struct.
677 (coff_find_nearest_line): obj_icof => coff_data.
678 (coff_swap_sym_{in,out}): Check that SYMNMLEN == E_SYMNMLEN.
679 (coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
680 and DIMNUM == E_DIMNUM.
681 * configure.in: Handle a29k-*-* hosts, and targets
682 a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
683 * libcoff-in.h: Add local_n_btmask, local_n_btshft,
684 local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
685 local_linesz to `coff_data' (tdata) struct.
686 (coff_data, coff_data_type, coff_tdata): Rename struct icofdata.
687 * config/h-ultra3: Handle a29k-*-* hosts as Ultracomputers.
689 Thu Sep 12 14:07:22 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
691 * Makefile.in: $(MAKE) for make, $(docdir) for doc
692 * doc/Makefile: redundant dependencies for Sun-make VPATH bug
694 Tue Sep 10 20:34:12 1991 John Gilmore (gnu at cygint.cygnus.com)
696 * aoutf1.h (sunos4_core_file_p): Release the right storage in

709 abfd->direction and complain if erroneous.
711 * Makefile.in: Add crude dependencies.
713 Tue Sep 3 13:46:19 1991 Steve Chamberlain (steve at cygint.cygnus.com)
715 * config/* aoutx.h configure* shortened all the h/tmake-xxxx
716 to h/t-xxxx files so that everything will work on System V.
718 Fri Aug 23 13:51:06 1991 John Gilmore (gnu at cygint.cygnus.com)
720 * aoutx.h: Add information on host-aout.c and how to configure
721 to use it, to the manual.
722 * configure.in: Tix typo.
723 * ecoff.c: If compiling for DEC3100, use trad_unix core files,
724 else dummy out the core file support.
725 * trad-core.c (trad_unix_core_file_p): If HOST_DATA_START_ADDR is
726 specified, use it to locate the data section.
727 * coffcode.h (coff_write_symbols): Declare buffer as bfd_bytes

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

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

829 29k coff by David Wood (wood@lab.ultra.nyu.edu).
831 Thu Jul 4 09:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
833 * Everything: created some new files, core.c format.c, reloc.c,
834 section.c and syms.c to split the functionality a bit better.
835 Cleaned up the rest of the files a bit, and added some
839 Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu)
841 * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl

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

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

936 from which it was split out. Now 64 bit version is built with a
937 -DHOST_64_BIT="long long" on the compile line.
940 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
942 Changed all the [get|put][name] routines to use [get|put]_[size
945 Put in support for 64 bit work. Now two versions of bfd may be
946 generated, according to the state of TARGET_64_BIT, one which is
947 32 bit only, and one which is 64/32 bits.
948 Created new back end 'demo64' to test 64 bit functionality.
950 Renamed some files to work on DOS.
952 * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
953 64bit transfer * icoff.c: added 64bit transfer * ieee.c: name

960 table. * oasys.c: Name change * opncls.c: Portability fixes *
961 srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
962 Added demo * aout32, aout64.c include aoutx.h * bout.c: used to
963 be called b.out.c * coffcode.h: used to be called coff-code.h, now
964 64bit ized. * demo64.c: 64 bit a.out back end
970 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
972 * libieee.h: Make ieee_data and ieee_ar_data macros usable
973 on LHS of assignment, even when using old compilers.
974 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
975 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
976 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
977 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
978 * targets.c: Add declaration of newsos3_vec.
981 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
983 * aout.c: fixxed some of the problems with filepos calculation.
984 (swap_ext_reloc): fixed problem with creation of relocs.
985 (aout_set_section_contents): fixed filepos problem
987 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
988 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
989 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
990 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
991 cleaned up. (coff_write_object_contents) cleaned up.
993 * ecoff.c: Totally different. Now supports ecoff fully.
995 * icoff.c: fixed problems in relocation callout.
997 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
999 * m68kcoff.c: updated target vector.
1001 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
1002 choose_reloc_size. (sunos4_write_object_contents) now calls
1003 choose_reloc_size so outputs relocs correctly, also calculates the
1004 size of the sections correctly.
1008 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1010 Merge Per Bothner's changes to modularize BFD a.out a bit.
1012 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
1013 * ieee.c: Cast enums to int before comparing them, for brain-
1015 * coff-code.h: Remove coff_get_section_contents, and use the
1016 generic one instead.
1018 * aout.c: Derive new module from sunos.c, containing generic
1019 support code for all kinds of a.out files.
1021 * sunos.c: Remove all code that goes in aout.c. Split out
1022 machine dependent followup in sunos4_object_p into
1023 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
1024 and redefine only the names we CHANGE, not all the names. Drop
1025 the little-endian vector, and rename the vector as sunos4 rather
1028 * b.out.c: Use aout.c routines for most of the work. Slight
1029 changes for the new regime. Remove close_and_cleanup and
1030 get_section_contents in favor of generics. New transfer vector
1033 * newsos.c: New support for Sony NEWS, another a.out format.
1035 * ecoff.c: Remove close_and_cleanup. New tvec regime.
1036 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
1037 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
1039 * opncls.c (bfd_close): Call format-dependent write_contents
1040 routine, if writing, before calling target-dependent
1041 close_and_cleanup routine (which is now always generic, I think).
1042 * srec.c: Use bfd_alloc instead of malloc. Remove
1043 close_and_cleanup and move code from it to
1044 srec_write_object_contents. Add write_contents to tvec.
1045 * targets.c: Remove a.out little vector, replace a.out big
1046 vector with SunOS vector. FIXME: Need Vax support again now.
1048 * libbfd.h: Add write_contents format-dependent-vector to the
1049 bfd_target vector. Supply a generic close_and_cleanup routine.
1050 * liba.out.h: Handle the new aout.c split. Add prototypes for
1051 all routines defined in aout.c. Rename "sunos" things to "aout"
1052 things. Add a few fields where needed for various formats.
1053 * Makefile.in: Add aout.c and newsos.c.
1055 * archive.c, ieee.c, oasys.c: Lint.
1057 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1060 changed forward declaration struct stat; to reduce warnings. Changed
1061 comment on bfd_h_<x>_x.
1063 * ../include/m68kcoff.h, ../include/intel-coff.h,
1064 ../include/m88k-bcs.h
1065 Now there are two incarnations of relocs, linenos and syments. One for
1066 internal digestion, and one full of char arrays for I/O. The original
1067 names have gone to detect errors.
1069 * Makefile.in, m68kcoff.c, targets.c
1070 Test new structure code with a 68k coff implementaion
1072 * coff-code.h, icoff.c, coffswap.c, libcoff.h
1073 Fixed all the places where there were problems with the size and
1074 alignments of structures on disk and structures in memory. #ifed out
1075 all the code in coffswap.c, since it should be done using the target
1078 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1080 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
1081 multiple reloc command.
1083 * sunos.c (sunos4_set_section_contents): Made it so that sections
1084 are always padded to their alignment size.
1086 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1088 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
1089 Clean up types and such (saber C problems).
1090 * ecoff.c: Clean up types and such. Remove routines that are
1091 not used. Fix up reading and swapping of shorts from files.
1093 Notes on bfd-0.5.2-patch1a, from Per Bothner:
1095 * a.out.vax.c: Remove two bogus "static" from prototypes.
1097 * ecoff.c: Got rid of lots of non-working junk (that had
1098 been copied directly from coff-code.h).
1099 Updated to be consistent with updates to icoff.c and coff-code.h.
1101 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
1102 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
1104 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
1105 but until the target_vector is automatically generated,
1106 it's as good as any. Note that the text offset is the only
1107 difference between NewsOS and SunOs (including magic numbers).
1108 (Most of the sunos_* routines should to renamed bsd_*
1109 and move to a bsd.c file. Then (and when the target_vector
1110 is automatically generated) it might make sense to create
1111 a separate Sony target.)
1113 * sysdep.h: Don't declare fread and fwrite. Causes trouble
1114 on some systems, and doesn't help on others.
1115 Similarly, only define X_OK if not already defined.
1117 * trad-core.c: Don't include sys/stat.h - at least
1118 on NewsOS 3, it has already been included.
1120 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1122 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
1123 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
1124 symbol tables if necessary when reading them in, so gdb can use
1125 them. Add "bfd_coff_" to the names so they won't conflict with
1126 names in calling programs. FIXME-soon: if coff-code.h is
1127 included in two BFD modules, this will cause duplicate
1128 definitions; the routines should be exported to a separate,
1129 common, module (probably along with a mess of other ones).
1131 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1133 Improve modtime support.
1135 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
1136 Remove #define for bfd_get_mtime. Remove gratuitous comment.
1137 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
1138 BUG: archive members still do not get correct mod times.
1140 Improve floating point support for core files.
1142 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
1143 (sunos4_core_file_p): Create a second registers section in the
1144 core file, called ".reg2", for the float registers.
1146 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1148 * many changes to improve archive handling; found a logic flaw in
1149 bfd_check_format which only just happened to work by cooncidence.
1151 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1153 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
1156 * bfd.h: changed type of udata in asymbol to void *, like it
1157 should be. Added bfd_reloc_dangerous enum member.
1159 * coff-code.h: Fixed it so that internally generated symbols get
1160 their values relocated correctly in all cases. Removed calls to
1163 * icoff.c: Not understanding the destination symbol of a reloc is
1164 not a failure any more, just 'dangerous'. This allows linking of
1165 b.out and coff images.
1167 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
1171 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1173 * sunos.c (translate_to_native_sym_flags): fixed
1174 sym_pointer->n_value so that symbols on the way out get their
1175 section relative values calculated correctly.
1177 * coff-code.h (mangle_symbols): fixed problem where tags were not
1178 being relocated for structs, enums, unions. Also various lints.
1180 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1182 * archive.c (get_elt_at_filepos): system_call_error returned
1185 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1187 * Resolve the use of no_error and system_call_error.
1188 The bfd library itself now will never set bfd_error to
1191 The code still needs to be combed to make sure all the error
1192 codes are correct. I suspect they are not always set correctly.
1194 * The names of all the messages have _ prepended because the sun
1195 bundled compiler can't distinguish from a macro which takes an
1196 argument and the same identifier in a non-macro context.
1198 * The reason for the above being that entry points which used to
1199 be trampoline functions are now just macros which expand to a
1200 direct call through the bfd's xfer vector.
1202 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
1203 must gas have its own version of everything (the gas version
1204 had the correct value)
1206 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1208 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
1209 properly support i960 architecture and output correct reloc stuff.
1211 * bfd.h: added prototype for bfd_printable_arch_mach, added
1214 * coff-code.h: Applied patches from chrisb to support i960
1215 architecture, zero relocs and swap them correcly and conditionally
1216 compiled the timestamp.
1218 * sunos.c: Made the default section alignment 2^3 so that doubles
1219 are done properly. Fixed the same reloc bug that was in b.out.c
1221 * sysdep.h: Now compiles on a Posix box
1223 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1225 * icoff.c: Fix comment on big-endian version.
1226 * coff-code.h: Make HAS_RELOC really work (it's backwards from
1227 F_RELFLG). Set F_AR32WR in output files if little endian
1230 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
1232 * archures.c fixed =/== typo
1234 * sunos.c added architecture stuff for output. Fixed
1235 bug where files where vma(data) != size(text)
1236 were processed wrong.
1238 * coff-code.h added a lint cast
1240 * (../include/a.out.sun4.h) fixed it so zmagic
1243 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
1245 * archive.c removed loads of includes, and fixed bug where string
1246 table didn't have a null at the end.
1248 * bfd.c fixed includes, added symbols argument to
1249 canonicalize_reloc entry point.
1251 * libbfd.c fixed includes and added some lint patches.
1253 * targets.c added both sorts of intel coff.
1255 * b.out.c fixed included, changed was the canonical
1258 * icoff.c added support for callj and big and little
1261 * opncls.c added chmod+xing for files with EXEC_P set.
1263 * sunos.c fixed includes. Changed default section
1264 alignement to words. Fixed relocation stuff to work with
1267 * bfd.h various new types added, prototype for new
1268 reloc calls, changed bfd->iostream to a void *
1269 to including files don't need stdio.h.
1271 * libcoff.h added conversion table to tie relocs to
1276 * coff-code.h fixed includes. Added code to support
1277 big and little endian formats. Various lints. Better
1278 processing of symbols. Changed reloc stuff to new
1281 * libbfd.h fixed includes
1284 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
1286 * bfd.h changed name of alignment entry in sec_struct to
1287 alignment_power, because of conflicting uses within bfd.
1288 Now it should be obvious that it's a 2**n alignment
1289 specifier. Removed start_pad, end_alignment, block, minsize,
1290 output_file_alignment, subsection_alignment and original_vma fields.
1291 Added align_power() macro. Fixed bfd_section_alignment
1292 acessor macros. Added bfd_symbol_same_target macro.
1294 * b.out.c (b_out_write_object_contents) fixed to use
1295 new alignment member. Fixed (callj_callback) to use section
1296 relative symbols properly.
1298 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
1299 Fixed (translate_from_native_sym_flags) to correctly make
1300 symbols section relative.
1302 * bfd.c (bfd_errmsg) fixed various enum cast problems.
1303 (bfd_make_section) took out initialization of obsolete members.
1304 (bfd_print_symbol_vandf) added
1306 * opncls.c (bfd_create) created.
1308 * coff-code.h (coff_new_section_hook) took away refs
1309 to obsolete members. (make_a_section_from_file) added
1310 conversion between alignment types. (coff_symbol_from)
1311 added. (coff_count_linenumbers) only counts linenumbers
1312 if symbol is of coff-type. (coff_mangle_symbols) only
1313 heavily mangles symbols if symbol is coff-type.
1314 (coff_write_symbols) various lints. (coff_write_object_contents)
1315 various lints and modification for alignment conversion.
1316 (coff_slurp_relocs) fixed for use with new asection shape.
1318 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
1320 * archive.c lots of lint
1322 * b.out.c added callj relocation support, upgrated reloc howto.
1323 Fixed so that asymbol and reloc records are output
1326 * bfd.c lots of lint, support for new bfd entry point
1329 * bfd.h changed definition of asymbol to contain pointer to
1330 owning bfd, removed target dependencies.
1332 * cache.c took out print statements, put in BFD_ASSERT calls.
1334 * coff-code.h various lints, corrected linenumber output
1335 functionality. Added support for new style asymbols and
1336 bfd_print_symbol. Fixed so that asymbol and
1337 reloc records are handled correctly. Added timestamp.
1339 * icoff.c Added support for new howto shape.
1341 * liba.out.h Added support for new asymbol shape
1343 * libbfd.c various lints
1345 * libbfd.h various lints
1347 * libcoff.h added support for new asymbol shape.
1349 * sunos.c various lints. Added support for new asymbol shape
1350 and bfd_print_symbol.
1352 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
1354 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
1355 pointer lint. Added support for callj relocation. Fixed bug where
1356 the last 32 bytes of the text section were overwritten by data. Fixed bug
1357 where archives of b.out didn't work due bfd_slurp_extended_name_table
1360 * sunos.c added support for n_other field. Braced the howto table so
1361 that it won't be affected by any lengthing of the howto struct typedef.
1364 * bfd.h added support for n_other field, added special_function
1365 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x

1370 Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl)
1372 * ChangeLog: Started ChangeLog for BFD.
1373 * ToDo: Create file for suggestions.
1375 * Makefile: Support easy loading into Saber C.
1376 Add dependencies for icoff.o and bcs88kcoff.o.
1377 Rename coff.c to coff-code.h. Change callers.
1379 * bfd.c (bfd_check_format): Allow the check_format routines
1380 to return the desired target vector, rather than just a Boolean.
1381 bfd.h (bfd_check_format): Change function pointer return type.
1382 archive.c (bfd_generic_archive_p): change callee.
1383 b.out.c (b_out_little_object_p, b_out_big_object_p,
1384 b_out_real_object_p): change callee.
1385 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
1386 in check_format transfer vectors that need a filler.
1387 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
1388 bcs88kcoff.c: change callee.
1389 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
1390 icoff.c: change callee.
1391 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
1393 * libbfd.c (zalloc): It should actually zero the storage!
1394 This was commented out for some reason.
1396 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
1397 This is so callers can avoid <stdlib.h> which doesn't exist
1400 * bfd.c (map_over_sections): Add debugging code, since I
1401 noticed the section count for sunos core files was bad, but only
1402 GDB had detected the problem.
1403 (bfd_set_section_lineno_size, bfd_set_section_linenos,
1404 bfd_get_section_linenos): Remove obsolete functions.
1405 (bfd_apply_relocations): Use longs, not ints, for the math.
1407 * bfd.h: Declare enum boolean and struct bfd_target as well
1408 as typedefs for them. Remove obsolete
1409 bfd_get_section_lineno_size.
1411 * cache.c: Make the "fdopen" support work. Keep better track
1412 of how many files are open. Centralize the opening of files
1413 and be sure bfd_open[rw] actually try to open the file. Evade
1414 linked list initialization problems.
1416 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
1418 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
1420 * cplus-dem.c: Delete file, since it is not part of BFD.
1422 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
1423 (bfd_openr, bfd_openw): Actually open the file, give error now.
1425 * sunos.c (sunos4_core_file_p): Set section count.
1426 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
1427 obsolete definitions.
1428 (_write_symbol_table): Initialize <idx> counter.
1429 (foop): Eliminate debugging code.
