1 Fri Dec 6 22:58:48 1991 K. Richard Pixley (rich at rtl.cygnus.com)
3 * Makefile.in: install using INSTALL_DATA, added standards.text
6 * configure.in: mark directory as target dependent. configure
7 nows works in objdir always so make file existence checks
10 Thu Dec 5 22:46:19 1991 K. Richard Pixley (rich at rtl.cygnus.com)
12 * Makefile.in: idestdir and ddestdir go away. Added copyrights
13 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
14 and mandir now keyed off datadir by default.
16 Wed Dec 4 10:14:17 1991 Steve Chamberlain (sac at rtl.cygnus.com)
17 * aoutf1.h (sunos_<size>_object_p, sunos4_callback): moved the
18 computation of arch and machine type so it's worked out before
19 some_aout_object_p is called.
20 * aoutx.h: (some_aout_object_p): don't set arch and mach to
22 * archures.c: add extra field 'section_align_power' to hold
23 default section alignment in object files.
24 * cpu-a29k.c, cpu-h8300.c, cpu-i386.c, cpu-i960.c, cpu-m68k.c,
25 cpu-m88k.c, cpu-mips.c, cpu-rs6000.c, cpu-sparc.c, cpu-vax.c:
26 initialize the new field.
27 * bout.c (b_out_callback): replace the text size, since aout
29 * aoutx.h: Documentation in the new style
31 Wed Dec 4 02:00:30 1991 John Gilmore (gnu at cygnus.com)
33 * bfd.c (bfd_get_mtime): Don't cache mtime any more; only
34 use the saved value if mtime_set is already set (intended
35 for archive files, though apparently not used yet).
37 Tue Dec 3 22:54:50 1991 John Gilmore (gnu at cygnus.com)
39 * targets.c: Revise comments about how to configure the target
40 vector, to match reality. Remove mention of obsolete methods.
41 Remove long lists of capitalized macros that turn into the same
42 thing in lowercase. Normal vector simply lists all known
43 lowercase xvec names; all other cases are handled by SELECT_VECS.
45 * config/mt-i386-coff: Set DEFAULT_VECTOR to real identifier,
48 * config/mt-i960-{coff,bout}: Use SELECT_VECS to make a short
49 list of supported targets.
51 Tue Dec 3 14:06:15 1991 Per Bothner (bothner at cygnus.com)
53 * archive.c (bsd_write_armap): The pad byte sometimes added to
54 the string table in a __.SYMDEF member is now
55 counted as part of the size of the string table.
56 This is compatible with the old ranlib, as well as Sun's.
58 Tue Dec 3 10:53:30 1991 Steve Chamberlain (sac at rtl.cygnus.com)
60 * srec.c: Rewrote to fix many bugs; now gets the record type
61 right, doesn't choke on input, sets the start address in an S9 and
62 fills in the filename on an S0.
64 Sat Nov 30 21:19:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
66 * cpu-h8300.c: Add support for MEMIND addressing mode
68 * coff-a29k.c: defined RELOC_PROCESSING to take the #ifdef out of
70 * coffcode.h: use the new macro if available
72 * elf.c (elf_corefile_note): cast malloc to avoid warning.
73 * Makefile.in: Fixed dependencies due to file rename
75 * aout-encap.c, aoutf1.h, aoutx.h, archive.c, bout.c, coff-a29k.c,
76 coff-h8300.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
77 coff-mips.c, coff-rs6000.c, cpu-h300.c, elf.c, i386aout.c,
78 newos3.c, stab-syms.c, syms.c: All these files have had their
79 #includes altered to point to the new places.
81 Fri Nov 29 20:04:49 1991 Fred Fish (fnf at cygnus.com)
83 * config/mh-i386v4, config/mh-i386-elf, hosts/h-i386v4.h: New files.
85 * configure.in: Add vendor "ncr" as supported per-target vendor.
86 Add svr4 case for i386 per-host case.
88 * elf.c (elf_object_p, elf_core_file_p): Add missing "break" to
91 Fri Nov 29 12:16:51 1991 Per Bothner (bothner at cygnus.com)
93 * syms.c (bfd_decode_symclass): Return 'A'
94 for symbols that are both absolute and global.
95 * archive.c (bfd_special_undocumented_glue): Return NULL
96 if bfd_ar_hdr_from_filesystem returns NULL.
98 Tue Nov 26 09:10:55 1991 Steve Chamberlain (sac at cygnus.com)
100 * Makefile.in: added coff-h8300
101 * configure.in: now h8 is a coff target
102 * cpu-h8300.c: fix various disassembly problems
103 * libcoff.h: took out some code which has been #0ed for a long
105 * targets.c: added h8 coff
106 * coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c
107 added new macro RTYPE2HOWTO to take a load of #ifdefs out of
109 * coffcode.h: Started to change the way machine dependencies are
110 handled, from the nest of #ifdefs to macros defined in the
111 including coff-<foo>.c
113 Fri Nov 22 08:11:42 1991 John Gilmore (gnu at cygnus.com)
115 * aoutx.h (some_aout_object_p): Set the `executable' bit
116 if the entry point is contained in the text segment, even if the
117 text segment is at location 0.
119 * coff-mips.c, coffcode.h: Peter Schauer's patch to kludge in
120 nonstandard MIPS sections (.rdata, .sdata, etc).
122 * aoutx.h, bfd.c, coffcode.h, ieee.c, oasys.c, targets.c: CONST lint.
123 * libbfd-in.h, libbfd.h, aoutx.h, coffcode.h, elf.c, libaout.h:
124 Rename ALIGN to BFD_ALIGN to avoid conflict with BSD <sys/param.h>.
126 * host-aout.c, trad-core.c: Fix write_armap prototypes. Lint.
128 Thu Nov 21 19:56:40 1991 Per Bothner (bothner at cygnus.com)
130 * stab-syms.c, syms.c: Moved bfd_stab_name() and bfd_stab_names[]
131 from syms.c to new file stab-syms.c. Also, since GNU extended
132 type codes such as N_SETT are no longer in ../include/stab.def,
133 include them manually.
134 * stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
135 bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
136 * libaout.h: Added prototype for aout_stab_name().
137 * Makefile.in: Update Makefile for new stab-syms.[co].
139 Thu Nov 21 11:50:49 1991 John Gilmore (gnu at cygnus.com)
141 * libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this
142 rather complicated seeming problem. Eliminate LOGICAL_ versions,
143 just make N_XXX work by excluding the header from the text segment.
144 * aoutx.h: Fix comments to match.
146 Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
148 * libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
149 LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
150 for the "logical" text segment (i.e. never consider the exec
151 header to be part of the text segment). This change is
152 needed for consistency with various other parts of bfd and ld.
153 * aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
154 and move calculation of obj_textsec(abfd)->size to libaout.h.
155 * bfd-in.h: Removed bogus ';'.
157 * Makefile.in: Add MINIMIZE flag to select lean
158 or bloated target_vector.
159 * targets.c: Use new MINIMIZE macro, and add trad_core if needed.
160 * newsos3.c: Fixes to ../include/aout64.h remove need
161 for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
163 Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
165 * aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h
166 handle both little and big-endian targets, with little
167 the default unless TARGET_IS_BIG_ENDIAN_P is defined.
168 * host-aout.c: Add FIXME note.
170 Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
172 * targets.c: Make the default target_vector contain
173 just &DEFAULT_VECTOR. This makes executables a lot smaller.
174 Old behavior can be gotten by defining ALL_TARGETS.
175 * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
176 Factored out common code into new file aout-target.h.
177 Saves a lot of duplicate code for a.out variants.
179 Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)
181 Get 'make headers' to work when configured with +subdirs.
182 * Makefile.in: Add $(subdir) to docdir path.
183 * doc/Makefile.in (protos): Add $(srcdir) prefix
184 to name of sed scripts.
186 Thu Nov 14 19:49:10 1991 Per Bothner (bothner at cygnus.com)
188 * aoutx.h (NAME(aout,print_symbol)): Fix thinko.
189 * syms.c (bfd_stab_names): Turn on new GNU_EXTRA_STABS macro
190 to include names of N_SETT etc.
192 Thu Nov 14 19:11:13 1991 Fred Fish (fnf at cygnus.com)
194 * elf.c: Add minimal support for ELF symbol tables. Generates
195 canonical bfd symbol tables from ELF symbol tables. Change the
196 name of some functions from bfd_<name> to elf_<name>.
198 * syms.c: Trivial fix to comment to remove a redundant "to".
200 Wed Nov 13 17:02:01 1991 John Gilmore (gnu at cygnus.com)
202 * coff-{i386,m68k,m88k}.c: Change name of file format to standard
203 form that GDB recognizes as COFF.
205 Wed Nov 13 09:09:41 1991 Steve Chamberlain (sac at cygnus.com)
207 * ieee.c (ieee_object_p): cast NULL correctly.
208 * configure.in: added harris host

212 Tue Nov 12 07:21:41 1991 John Gilmore (gnu at cygnus.com)
214 * coff-m88k.c (coff_write_armap): Just #undef it.
216 Mon Nov 11 20:30:18 1991 Steve Chamberlain (sac at cygnus.com)
218 * Makefile.in: standardize on MINUS_G to disable debugging
219 * coff-m88k.c: create coff armaps instead of bsd ones.
220 * opncls.c (bfd_close_all_done), (bfd_close): Mask out random bits

225 * elf.c: Additions to support ELF format core files.
226 * config/mh-amix: Add -DHAVE_PROCFS to HDEFINES, since host
227 has support for /proc (all the include files in particular).
229 Mon Nov 11 18:36:47 1991 Per Bothner (bothner at cygnus.com)
231 * aoutx.h (NAME(aout,find_nearest_line)): Handle the case
232 of two N_SO stabs, one for directory, and one for filename.
234 * bfd-in.h (print_vma): Factor out duplicate definition.
236 Exit a little more gracefully when malloc returns NULL.
237 * libbfd.c: New function bfd_xmalloc (malloc wrapper).
238 * opncls.c, syms.c, bout.c, aoutx.h: Replace malloc by bfd_xmalloc.
239 * libbfd.h: Rre-generated due to libbfd.c update.
241 Sat Nov 9 13:45:01 1991 Fred Fish (fnf at cygnus.com)
243 * config/mt-m68k-elf: Define DEFAULT_VECTOR as elf_big_vec.
245 * elf.c (elf_object_p): Don't try to create a bfd section for
246 the first ELF section header. It is just a placeholder.
248 Sat Nov 9 03:04:26 1991 John Gilmore (gnu at cygnus.com)
250 * coff-rs6000.c, config/mh-rs6000: Make it work on archive and
251 core files, when compiling native.
252 * hosts/h-rs6000.h: Define FASCIST_FDOPEN for bfd_fdopenr.
254 FIXME: The aoutf1.h change below needs to be reversed back
257 Thu Nov 7 11:03:55 1991 Steve Chamberlain (sac at rtl.cygnus.com)
259 * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
260 manipulation of lnno fields in lineno structs in a coff-<f>.h
261 independent way. Override it in coff-<f>.h to your favourite
262 number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
263 (coff_swap_lineno_out): modified to use the new macros.
265 Mon Nov 4 11:38:33 1991 Steve Chamberlain (sac at cygnus.com)
267 * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
268 unknown arch when the magic number doesn't specify the
269 architecture, since some OSs (eg old sun3s) don't set the number, and
270 020 is probably the right answer anyway.
272 Sun Nov 3 12:07:08 1991 Per Bothner (bothner at cygnus.com)
274 * hosts/h-news.h, hosts/h-rtbsd.h:
275 Get rid of MISSING_VFPRINTF, since libiberty provides one.
276 * bfd-in.h (bfd_print_symbol_type_hopw enum): Add new option
277 bfd_print_symbol_nm, for use by nm.
278 * aoutx.h (NAME(aout,print_symbol)): Add code for new
279 bfd_print_symbol_nm option, to print in nm format.
280 * coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
281 oasys.c (oasys_print_symbol): Provide stub implementations
282 for bfd_print_symbol_nm.
283 * syms.c: New function bfd_decode_symclass, used by nm printer.
284 New function bfd_stab_name to look up string name of stab code.
286 Sat Nov 2 14:26:03 1991 Steve Chamberlain (steve at cygnus.com)
288 * Makefile.in: Added ctor.c
289 * archures.c (bfd_default_arch_struct) added
290 bfd_default_reloc_type_lookup.
291 * coffcode.h: removed a load of #if 0ed code.
292 (coff_compute_file_section_positions): now works out the section
293 alignment and size correctly in all cases.
294 (coff_get_symtab): looks for constructor symbols and calls the
295 right function when they're found. (coff_canonicalize_reloc):
296 knows when a section is full of constructors and does the right
298 * cpu-m88k.c: Added default_reloc_type lookup to the architecture
300 * libbfd-in.h: (bfd_default_reloc_type_lookup) defun added.
301 * libcoff.h: removed #if 0ed code
302 * reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
303 arch independent constructor relocation type.
304 (bfd_reloc_type_lookup): removed the comment "this will go away"
305 since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
306 reloc which is used when BFD_RELOC_CTOR falls through to give a
307 default 32bit reloc for constructors.
308 (bfd_default_reloc_type_lookup): added.
309 * aoutf1.h: fixed SEGMENT_SIZE typo.
311 Thu Oct 31 18:23:06 1991 John Gilmore (gnu at cygnus.com)
313 * coff-rs6000.c: Change name to "aixcoff-rs6000", to avoid
314 matching prefix "coff".
315 * coffcode.h (coff_swap_aux_in, coff_swap_aux_out): Handle
316 rs/6000 csect records.
318 Sun Oct 27 16:56:58 1991 Steve Chamberlain (steve at cygnus.com)
320 * coff-m88k.c, targets.c: change name of m88k_bcs to m88kbcs
321 * configure.in: add motorola delta88 cases
322 * libbfd.h, libbfd-in.h, archive.c, ieee.c, elf.c, srec.c: fix
323 write_armap prototype
324 * libbfd.c: add doc on bfd_write_bigendian_4byte_int
326 Fri Oct 25 02:48:19 1991 John Gilmore (gnu at cygnus.com)
328 * Rename COFF-related files in `coff-ARCH.c' form.
329 coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
330 coff-mips.c, coff-rs6000.c to be exact.
332 * Makefile.in: Only supply TARGET_DEFAULTS to targets.c, reducing
334 * config/mt-*: Ditto.
336 Thu Oct 24 22:40:07 1991 John Gilmore (gnu at cygnus.com)
338 RS/6000 support, by Metin G. Ozisik, Mimi Phûông-Thåo Võ, and
339 John Gilmore. Archive support from Damon A. Permezel.

351 (bfd_swap_aouthdr_in): Handle lots more members.
352 (make_a_section_from_file): If section has already been seen,
353 just return false rather than overwriting it.
354 (coff_real_object_p): Understand incoming magic numbers.
355 (coff_set_flags): Understand outgoing magic numbers.
356 (coff_compute_section_file_positions): outgoing aouthdr magic #.
357 (build_debug_section): Add fn for reading debug string section.
358 (get_normalized_symtab): Handle symbol names in debug string section.
359 Remove unused obj_string_table.
360 (coff_slurp_symbol_table): Handle rs6000-specific storage classes.
361 * aoutx.h (translate_from_native_sym_flags, N_SET*): Check for
362 existing section before making one.
363 * cpu-rs6000.c: New file.
364 * rs6000coff.c: New file.
366 Thu Oct 24 02:03:24 1991 Fred Fish (fnf at cygnus.com)
368 * elf.c: Add partial support for ELF format corefiles. Still needs
369 support for extracting registers from corefiles.
371 * config/t-m68k-elf: Set DEFAULT_VECTOR to elf_big_vec.
373 * config/{h-amix,h-dgux,h-irix3,h-ultra3}: For systems where
374 RANLIB is defined as echo, send the output to /dev/null to help
375 reduce clutter in the output from doing a make.
377 Mon Oct 21 17:48:48 1991 John Gilmore (gnu at cygnus.com)
379 * hosts/h-vaxult.h: Remove malloc/free decls covered in stdlib.h.
380 Fix HOST_PAGE_SIZE and HOST_SEGMENT_SIZE. From David Taylor.
382 Mon Oct 21 09:34:11 1991 Steve Chamberlain (steve at rtl.cygnus.com)
384 * coffcode.h (coff_compute_section_file_positions): make it pad
385 section size out if there are alignment restrictions so that the
386 image will be ok on a system where section positions are worked
387 out by accumulating sizes rather than from the section headers.
388 * targets.c (proto write_armap). Changed orl_count to unsigned.
389 * opncls.c (bfd_close_all_done). Added so that generative
390 programs like gas can close a bfd without causing bfd confusion.
391 * libbfd.h (changed becuase of protos)
392 * amdcoff.c: messed with the way that jmp displacements are
393 calcualated. This may not yet be totally correct.
394 * archive.c (coff_write_armap): rewrote the way that ranlibs are
396 * coffcode.h (fixup_symbol_value): now doesn't core dump if a non
397 abs symbol has no section (like a register symbol).
398 (coff_write_symbol) now zeros auxent before filling it up to help
399 with sensitive applications.
400 * libbfd.c (bfd_write_bigendian_4byte_int): added.
402 Wed Oct 16 22:58:45 1991 John Gilmore (gnu at cygnus.com)
404 * bfd.c: Make sure we don't get a macro strerror().
405 * opncls.c (bfd_fdopenr): If FASCIST_FDOPEN, use "r", not "r+".
406 * trad-core.c (trad_unix_core_file_failing_command): Suppress
407 attempt to recover command, ifdef NO_CORE_COMMAND.
408 * hosts/h-tahoe.h: Add FASCIST_FDOPEN and NO_CORE_COMMAND;
410 * hosts/h-i386v.h: Use <utime.h>, not <sys/utime.h>, unlike POSIX.
412 Wed Oct 16 12:43:49 1991 Per Bothner (bothner at cygnus.com)
414 * archive.c (bsd_write_argmap): The size of the ranlib structures
415 should not include the size field itself.
416 * aoutx.h, libaout.h (NAME(aout, sizeof_headers)): Use
417 adata(abfd)->exec_bytes_size field instead of constant macro,
418 because aoutx.h compiles to a simple .o file shared by
419 all 32-bits a.out targets.
421 Wed Oct 16 11:11:05 1991 John Gilmore (gnu at cygnus.com)
423 * configure.in: Allow i386-sco-sysv.
424 * bout.c: Remove unused i960_align; lint dummy core file handlers.
427 * host-aout.c: New strategy. We use common code, include files,
428 and data structures to handle the file, but set a few parameters
429 from the host's config file (page size, text start addr, etc).
430 * libaout.h: Define HP BSD machine types.
431 * aoutf1.h: Handle reading a.outs with these types.
433 * trad-core.c: Pass the u.u_ar0 value as the negative of the
434 virtual-memory-address of the .reg section. We can't just make a
435 section for "all the regs and nothing else" because only GDB knows
436 exactly where the regs are (scattered around the upage and stack).
437 Clean up memory allocation. Remove big- and little-endian
438 vectors, replace with single vector; this only runs on the host,
439 in host byte order. Replace byteswap routines with aborts in case
441 * targets.c: There's only one trad_core_vec now.
442 * aoutf1.h (sunos_core_file_p): VMA of .reg* now needs to be 0.
444 Tue Oct 15 08:29:03 1991 John Gilmore (gnu at cygnus.com)
446 * hosts/h-amix.h (free): Fix prototype.
448 * aoutx.h: Don't use NULL as an integer, for braindead systems
449 that declare it as (void *)0. (From Peter Schauer.)
451 Mon Oct 14 17:20:47 1991 Per Bothner (bothner at cygnus.com)
453 * opncls.c (bfd_fdopenr): Add parentheses to avoid reported
454 problem with bad Ultrix system headers.
455 * aoutx.h (NAME(aout,set_section_contents)): Try to handle the
456 various kinds of alignments for the various kinds of
459 Mon Oct 14 14:23:10 1991 John Gilmore (gnu at cygnus.com)
461 * doc/Makefile: Don't assume . is on the path (from James Clark).
463 Fri Oct 11 22:45:14 1991 John Gilmore (gnu at cygnus.com)
465 * Makefile.in: Avoid Sun Make VPATH bugs.
466 * targets.c: Declare trad_core vectors extern.
468 Fri Oct 11 13:03:02 1991 Per Bothner (bothner at cygnus.com)
470 * coffcode.h: Moved ALIGN macro to libbfd.h. Removed i960_align.
471 * libbfd.h: Moved ALIGN macro here.
472 * bout.c (b_out_callback): Replace i960_align by align_power.
474 * libaout.h (struct aoutdata): Added fields page_size,
475 segment_size and exec_bytes_size. These help generic code
476 (in aoutx.h and libaout.h) to figure out where to align
477 the various segments in a demand paged file.
478 * libaout.h (WRITE_HEADER): Use new (struct aoutdata) fields
479 to decide if the exec header counts in a_text (text segment size).
480 Also, assume D_PAGED flag is set; don't set it here.
481 * bout.c (b_out_callback): Add initialization of
482 adata fields page_size, segment_size, and exec_bytes_size.
483 * host-aout.c (NAME(host_aout, callback) and
484 NAME(host_aout,mkobject): Ditto.
485 * i386aout.c (aout386_callback) and new aout386_mkobject): Ditto.
486 * newos3.c (newsos3_callback) and new newsos_mkobject): Ditto.
487 * aoutf1.c (sunos4_callback) and new sunos_mkobject): Ditto.
488 * aoutx.h (NAME(aout,some_aout_object_p)): Don't subtract
489 EXEC_BYTES_SIZE from the a_test size; this is only appropriate
490 for some systems (mainly sunos), so do it in the callback instead.
491 Same routine: Add stuff to the THIS_IS_ONLY_DOCUMENTATION comment.
492 * aoutx.h (NAME(aout,set_section_contents): Change the way
493 filepos and size of sections are carried out to support
494 older styles of demand paged executables.
497 Fri Oct 11 12:33:36 1991 Steve Chamberlain (steve at cygnus.com)
499 * bfd-in.h: Added more macros to COFF_SWAP_TABLE.
500 * bfd.c: Added macros to enable gas to swap coff records.
501 * coffcode.h: Make the coff_swap_*_out routines return the number
502 of bytes swapped, and cleaned up their prototypes.
503 * configure.in: Added ebmon/coff support
504 * ecoff.c: Changed null definitions of coff_swap_*_out to conform
506 * targets.c: Added new entry points for coff swapping
508 Fri Oct 11 03:01:52 1991 John Gilmore (gnu at cygnus.com)
510 Restructure configuration scheme for bfd, binutils, ld.
512 * include/sys/h-*.h: Move to bfd/hosts/h-*.h.
513 * configure.in: Revise to symlink sysdep.h to hosts/h-xxx.h.
514 Change some config names to match other dirs.
515 * *.c: Include bfd.h before sysdep.h, so ansidecl and PROTO()
517 * Makefile.in: Use -I. to get sysdep.h. Remove refs to
519 * cpu-i960.c: Strncmp needed a length arg.
520 * ecoff.c: Don't ever call trad_unix_core_file_p from here.
521 * i386aout.c: Remove dead N_TXTOFF override.
522 * trad-core.c: Don't disable the whole file if SUN4_SYS.
523 * config/: Rename some config files to match up h-*.h names.
524 Remove all the HOST_SYS definitions from the config files.
525 * hosts/h-amix.h, h-i386v.h: Define POSIX_UTIME, not USG.
526 * hosts/h-hp9000.h: Remove USG comment.
527 * hosts/h-rs6000.h: Include <stdlib.h> for malloc.
528 * hosts/h-news.h, h-sparc-64.h: New config files that had
529 previously been kludged in the <sysdep.h> file.
531 Thu Oct 10 17:54:08 1991 John Gilmore (gnu at cygnus.com)
533 * config/*: trad-core support is HOST dependent, not target
534 dependent. Target config files only set DEFAULT_VECTOR and/or
535 other vector elements. Exception: when host-aout.c is in use,
536 in which case we're forced to assume we're native (hp, vax,
537 tahoe). Rename XDEPFILES to HDEPFILES.
538 * Makefile.in: Rename XDEPFILES.
539 * config/h-sun*: Don't force static linking.
540 * trad-core.c: Document how to use it nowadays.
541 * i386aout.c, newsos3.c: Clean up.
542 * i386coff.c: Allow 386 coff files to be used as core files too
543 (for reading core files from embedded systems).
545 Tue Oct 8 15:30:39 1991 John Gilmore (gnu at cygnus.com)
547 * Add i386aout.c for a.out support on the i386.
549 Tue Oct 8 12:18:54 1991 Roland H. Pesch (pesch at cygnus.com)
551 * reloc.c, section.c, syms.c, targets.c: correct info-node
552 structure in *doc* comments.
553 doc/Makefile: stop hiding complaints from makeinfo.
555 Sun Oct 6 19:10:06 1991 John Gilmore (gnu at cygnus.com)
557 * aoutx.h (...some_aout_object_p): Take a third parameter,
558 the internal_exec struct, and avoid ever looking at an
559 external_exec. All callers changed to read the entire
560 external_exec struct, swap and check its magic number,
561 swap in the whole structure, and pass the swapped-in version to
563 * bout.c: Bring into modern era. Use single _object_p routine
564 for big- aand little-endian. Provide internal and external
565 exec header structs. Use separate swap-in and swap-out routines.
567 * libaout.h: Move struct internal_exec from ../include/aout64.h
568 to here. Add obj_symbol_entry_size to struct aoutdata.
569 * aoutx.h (...some_aout_object_p): Set obj_symbol_entry_size.
571 * ../include/aout64.h: Change EXTERNAL_LIST_SIZE to
572 EXTERNAL_NLIST_SIZE. Callers changed.
574 Fri Oct 4 18:18:46 1991 John Gilmore (gnu at cygnus.com)
576 * bfd.c: Remove strerror() to libiberty.
578 * elf.c: Remove elf_set_section_contents, use generic one. Lint.
579 * libbfd-in.h, libbfd.c: Add bfd_generic_set_section_contents.
580 * libbfd.c (bfd_generic_{get,set}_section_contents): Check that
581 last byte of transfer, not first byte, is within the section.
583 * host-aout.c: Remove `BSD' archive support. Lint.
585 * archures.c: Rename `struct bfd_arch_info_struct' to `struct
586 bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
587 `bfd_arch_info_type'. All uses changed.
588 * reloc.c: Rename `bfd_reloc_status_enum_type' to
589 `bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
590 to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
591 it needs a better name.) All uses changed.
592 * targets.c: Rename `enum target_flavour_enum' to `enum
593 target_flavour', and remove the `_enum' from all of the enum
594 values themselves. All uses changed.
596 * configure.in, config/h-i386mach: i386 mach host.
597 * config/t-i386-aout: Use host-aout.c.
599 * trad-core.c: Give it its own xvec's to make it independent
600 of other file formats.
601 * ecoff.c, host-aout.c: Remove refs to trad-core.
602 * config/t-dec3100, t-hp300bsd, t-tahoe, t-vax: Define TRAD_CORE.
603 * targets.c: #ifdef TRAD_CORE, include it in the vector.
605 Fri Oct 4 17:38:03 1991 Steve Chamberlain (steve at cygnus.com)
607 * reloc.c: Extended NEWHOWTO macro
608 * ieee.c: Changed the way 8bit pcrel is done
609 * cpu-h8300.c: got the registers in the right order
611 Thu Oct 3 19:39:55 1991 John Gilmore (gnu at cygnus.com)
613 * bfd-in.h: enum boolean => enum bfd_boolean for SVR4. Gumby's
614 prediction is vindicated!
616 * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
617 Remove refs to howto.c, since Steve forgot.
619 Thu Oct 3 07:49:21 1991 Steve Chamberlain (steve at cygnus.com)
621 * elf.c: took the abort out of set_arch_mach so that objdump -i will
622 still work. Now allows any architecture/machine to be set.
624 Wed Oct 2 13:50:35 1991 Steve Chamberlain (steve at cygnus.com)
626 * howto.c deleted and moved code to reloc.c
628 * libbfd.h, libbfd-in.h removed $id stuff for real
630 * cpu-h8300.c Made it match various different spellings of h8300.
632 * archures.c: Took out the first char filter which made it only
633 look for a cpu/arch match when the first chars of supplied and
634 tested names were the same.
636 * targets.c removed oasys stuff, pending someone to fix the bugs
640 Tue Oct 1 12:29:44 1991 John Gilmore (gnu at cygnus.com)
642 * Makefile.in, configure.in, targets.c, elf.c: Add preliminary
643 ELF support good enough for GDB.
644 * configure.in, config/h-amix, config/t-m68k-elf: Handle
645 m68k-cbm-svr4 host and target.
646 * config/t-m68k-coff, t-m88k-coff, t-m88k-aout: Make files nonempty
647 so `diff' and `patch' can cope.
649 Tue Oct 1 11:24:31 1991 Steve Chamberlain (steve at cygnus.com)
651 * archures.c: removed texinfo error
653 * init.c: added texinfo hooks, and removed initialization error
656 * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
659 Tue Oct 1 05:02:53 1991 John Gilmore (gnu at cygnus.com)
661 * cpu-i960.c: Avoid numerical count of initializers.
663 Vax Ultrix changes from David Taylor <taylor@think.com>:
664 * host-aout.c: Make little-endian vector really little-endian.
665 * configure.in: Separate vax and tahoe cases, handle ultrix.
666 * config/t-vax: Add trad-core.o.
667 * config/h-vaxult: New host system.
669 Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
671 * bfd-in.h VERSION, change version number to 0.18, this makes a
672 gap, but now is the same as the linker version number.
674 * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
675 cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
676 files will eventually contain processor specific bits for bfd,
677 like strange relocation information and dis/assembly. So far only
678 the H8 has been even partially done. This work also ties in with
679 the change in handling architectures.
681 * amdcoff.c: (a29k_reloc) fix error message.
683 * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
684 discover the architecture of the bfd. (sunos4_callback) calls the
685 function bfd_set_arch_mach rather than stuffing stuff directly
686 into the bfd. (sunos4_write_object_contents), changed names of
689 * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
690 setup the environment.
692 * archive.c: (bfd_slurp_coff_armap) coff archives always have the
693 headers in big endian format, regardless of the endianess of the
696 * archures.c: totally changed. Now an architecture is represented
697 with a pointer to an info structure rather than an enumerated type
698 and a long. The old info is available as two elements in the
699 structure. Future enhancements to architecure support will
700 involve pointers to methods being placed into the info structure.
702 * bfd.c: changed the definition of the bfd structure for the new
705 * bout.c: (b_out_set_arch_mach) changed to use the new
706 architecture mechanism.
708 * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
709 the new architecture mechanism.
711 * configure.in: added h8 stuff.
713 * ieee.c: too many changes to note. Now ieee files written with
714 bfd gas and ld can be read by gld and ieee only linkers and
717 * libbfd.c, libbfd.h: changed prototype of bfd_write.
719 * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
720 than fixing the structure directly.
722 * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
723 than fixing the structure directly.
725 * opncls.c: (new_bfd) makes sure that bfd_init has been called
726 before opening a bfd.
728 * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
729 rather than fixing the structure directly.
731 * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
732 in the t/hmake file) a user can select which backends they want
733 linked with bfd without changing the source.
735 * init.c: new, looks after initializing modules.
737 * howto.c: for future use, will allow an application to work out
738 what cookie to use as a handle on a relcoatio howto.
740 Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
742 * srec.c: Better error checking, partly from Peter Schauer.
743 (srec_object_p): Avoid assuming any file that starts with 'S' is
744 an S-record file! (Check for 3 uppercase-hex digits after it.)
745 (ISHEX): Define new macro for checking supposedly hex characters.
746 (pass_over): Treat as EOF any S-record line that:
747 * doesn't have hex in either size character
748 * produces a size larger than 0x7F
749 * has an unrecognized type number
751 Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
753 * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
754 opncls.c: Lint (saber actually).
756 Thu Sep 26 11:24:24 1991 Per Bothner (bothner at cygnus.com)
758 * libaout.h (WRITE_HEADERS): Set header's a_text field always.
759 * newsos3.c: Fixed two types: newos3 -> newsos3.
760 * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
761 to use correct segment.
763 Mon Sep 23 18:24:34 1991 Per Bothner (bothner at cygnus.com)
765 * aoutx.h (print_symbol): Handle missing symbol->name.
767 Fri Sep 20 12:26:01 1991 Stu Grossman (grossman at cygnus.com)
769 * aoutf1.h (swapcore_sparc): Change name of USRSTACK, fix comment
772 Tue Sep 17 17:23:49 1991 Stu Grossman (grossman at cygnus.com)
774 * oasys.c, configure.in, config/h-irix3, config/t-irix3:
775 add sgi/irix support.
777 Thu Sep 12 14:29:09 1991 John Gilmore (gnu at cygint.cygnus.com)
779 Changes for the AMD 29000 Ultracomputer port from David Wood.
782 * opncls.c (bfd_fdopenr): Handle NO_FCNTL.
784 * Makefile.in: Make subdirs work by using $(INCDIR) in the
787 * coffcode.h (coff_real_object_p): Pass information about the
788 current file's coff symbol format to BFD via the coff_data struct.
789 (coff_find_nearest_line): obj_icof => coff_data.
790 (coff_swap_sym_{in,out}): Check that SYMNMLEN == E_SYMNMLEN.
791 (coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
792 and DIMNUM == E_DIMNUM.
793 * configure.in: Handle a29k-*-* hosts, and targets
794 a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
795 * libcoff-in.h: Add local_n_btmask, local_n_btshft,
796 local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
797 local_linesz to `coff_data' (tdata) struct.
798 (coff_data, coff_data_type, coff_tdata): Rename struct icofdata.
799 * config/h-ultra3: Handle a29k-*-* hosts as Ultracomputers.
801 Thu Sep 12 14:07:22 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
803 * Makefile.in: $(MAKE) for make, $(docdir) for doc
804 * doc/Makefile: redundant dependencies for Sun-make VPATH bug
806 Tue Sep 10 20:34:12 1991 John Gilmore (gnu at cygint.cygnus.com)
808 * aoutf1.h (sunos4_core_file_p): Release the right storage in
810 (sunos4_core_file_matches_executable_p): Fix header comparison.

812 * bout.c, icoff.c, ieee.c, libbfd.c, oasys.c: gcc -O -W lint.
814 Wed Sep 4 00:44:52 1991 John Gilmore (gnu at cygint.cygnus.com)
816 Allow GDB to patch object files.
818 * aoutf1.h (sunos_core_file_p): Set SEC_HAS_CONTENTS on all sections.
819 * trad-core.h (trad_unix_core_file_p): Ditto.
820 * aoutx.h (aout_set_section_contents): On first output, check
821 abfd->direction and complain if erroneous.
823 * Makefile.in: Add crude dependencies.
825 Tue Sep 3 13:46:19 1991 Steve Chamberlain (steve at cygint.cygnus.com)
827 * config/* aoutx.h configure* shortened all the h/tmake-xxxx
828 to h/t-xxxx files so that everything will work on System V.
830 Fri Aug 23 13:51:06 1991 John Gilmore (gnu at cygint.cygnus.com)
832 * aoutx.h: Add information on host-aout.c and how to configure
833 to use it, to the manual.
834 * configure.in: Tix typo.
835 * ecoff.c: If compiling for DEC3100, use trad_unix core files,
836 else dummy out the core file support.
837 * trad-core.c (trad_unix_core_file_p): If HOST_DATA_START_ADDR is
838 specified, use it to locate the data section.
839 * coffcode.h (coff_write_symbols): Declare buffer as bfd_bytes
840 rather than as chars (lint).
842 Thu Aug 22 22:20:19 1991 Stu Grossman (grossman at cygint.cygnus.com)

855 * trad-core.c (trad_unix_core_file_p): Use HOST_TEXT_START_ADDR,
856 etc, rather than TEXT_START_ADDR.
857 * host-aout.c: Remove #if 0 around whole thing.
858 Update to modern (32/64-bit) a.out naming conventions.
859 Include a large chunk of ../include/a.out.gnu.h to get macros that
860 are not defined by the system include files.
861 (host_aout_{32,64}_write_object_contents): Use the WRITE_HEADERS
862 macro used by the other a.out implementations.
863 * Makefile.in: Give dependencies to OPTIONAL_BACKENDS.
865 Wed Aug 21 14:33:06 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
867 * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of
868 texdoc and psdoc; make these depend on generated .texi's
870 * scanit, (new) unPROTO: turn PROTO macros into ANSI declarations in
873 * bfd.c, reloc.c, syms.c: minor spelling/wording fixes in doc
876 * Makefile.in, awkscan-ip, awkscan-p, intobfd,
877 libbfd.h, libcoff.h, tolibcoff; new bfd-in.h, libbfd-in.h,
878 libcoff-in.h: (a) use separate files for invariant parts of bfd.h,
879 libbfd.h, and libcoff.h; (b) in generated parts of same, use less
880 obtrusive marks indicating .c origins.
882 * bfd.texinfo: generalize most references to linker

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

940 * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
941 29k coff by David Wood (wood@lab.ultra.nyu.edu).
943 Thu Jul 4 09:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
945 * Everything: created some new files, core.c format.c, reloc.c,
946 section.c and syms.c to split the functionality a bit better.
947 Cleaned up the rest of the files a bit, and added some
951 Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu)
953 * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
954 really takes 3 arguments, patched code and ammended prototypes.
956 Fri Jun 14 13:19:40 1991 Steve Chamberlain (steve at cygint.cygnus.com)
958 * ../include/bfd.h (struct bfd_target): Added new field
959 "align_power_min" which contains the minimum alignment for a
960 section. This is used in coff_new_section_hook. The field
961 insertion necessitates an update of all backends..
963 * aoutf1.h jump table field inserted
965 * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
968 * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
969 table field inserted.
971 * coffcode.h(just about everything) Now patches up symbol tables
972 using a different mechanism. The Intel major bug has been fixed,
973 and the linker can self host on the Aviion and be debugged with
976 * ecoff.c: new include and jump table patch, i386coff.c: new
977 include and jump table patch, icoff.c: new include and jump table
978 patch, ieee.c: can now read archives containing ieee modules.,
979 libcoff.h: added (combined_entry_type), libieee.h: uped max
980 sections to 20, m68kcoff.c: new include and jump table patch,
981 m88kbcs.c: new include and jump table patch, oasys.c: various bugs
982 fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.
983 srec.c: jump table patch. trad-code.c fixed #IF typeo
985 Fri Jun 7 12:35:46 1991 Sean Fagan (sef at cygint.cygnus.com)
987 * coffcode.h (coff_swap_aux_in): added else case to deal with
988 filenames less than 9 characters.
991 Thu Jun 6 18:27:38 1991 Steve Chamberlain (steve at cygint.cygnus.com)
993 * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
995 * srec.c: now allows any number of sections to be created in a
996 file. Outputs addresses of the right length.
998 Thu May 30 15:30:10 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1000 * bfd.c (bfd_check_format): Fixed problem where when a defaulted
1001 target didn't match, the format got set to the attempted match,
1002 breaking a future test.
1004 *../include/i386coff.h : fixed typo in type field with size
1006 * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
1007 support in the jump table for the swapping routines exported to
1008 gdb. Now gdb works with the 386.
1010 Tue May 28 17:21:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1012 * Merge in changes from gdb-3.95 release.
1013 Makefile.in: Allow hmake and tmake files to add OFILES.
1015 bfd.c: support specific targets as well as searching. When
1016 searching, take default target in preference to others.
1018 ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
1019 liba.out.h: Don't hard-code file offsets; use N_ macros for them.
1020 libbfd.h: Support specific targets as well as searching.
1021 opncls.c: Support specific targets as well as searching.
1022 targets.c: Search is short-circuited if default target matches.
1023 liboasys.c, libieee.c: Undo bothner changes that make macros
1024 work to the left of assignment, but which depend on the
1025 representations of different pointer types being the same.
1027 Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1029 * i386coff.c: created.
1030 * coffcode.h: added support for 386.
1031 * Makefile.in: added support for 386.
1032 * ../include/i386coff.h: created
1034 Wed May 22 07:26:38 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1036 * coffcode.h: removed all put_x_<sizes>
1037 * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
1041 Tue May 21 08:58:58 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1043 * opncls.c: Changed obstack_chunk_alloc use xmalloc
1045 Mon May 20 17:12:17 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1047 * everything: Removed sysdep.h from bfd.h and put back into files
1048 from which it was split out. Now 64 bit version is built with a
1049 -DHOST_64_BIT="long long" on the compile line.
1052 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1054 Changed all the [get|put][name] routines to use [get|put]_[size
1057 Put in support for 64 bit work. Now two versions of bfd may be
1058 generated, according to the state of TARGET_64_BIT, one which is
1059 32 bit only, and one which is 64/32 bits.
1060 Created new back end 'demo64' to test 64 bit functionality.
1062 Renamed some files to work on DOS.
1064 * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
1065 64bit transfer * icoff.c: added 64bit transfer * ieee.c: name
1066 chage, 64 bit transfer. * liba.out.h: Split out common code from
1067 sunos and newsos into liba.out. Name changes and prototype mods. *
1068 libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
1069 prototypes for new functions. * libcoff.h: lint * libieee.h: make
1070 work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
1071 change and 64bit stuff.* newsos3.c: common code removed, new jump
1072 table. * oasys.c: Name change * opncls.c: Portability fixes *
1073 srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
1074 Added demo * aout32, aout64.c include aoutx.h * bout.c: used to
1075 be called b.out.c * coffcode.h: used to be called coff-code.h, now
1076 64bit ized. * demo64.c: 64 bit a.out back end
1082 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1084 * libieee.h: Make ieee_data and ieee_ar_data macros usable
1085 on LHS of assignment, even when using old compilers.
1086 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
1087 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
1088 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
1089 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
1090 * targets.c: Add declaration of newsos3_vec.
1093 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1095 * aout.c: fixxed some of the problems with filepos calculation.
1096 (swap_ext_reloc): fixed problem with creation of relocs.
1097 (aout_set_section_contents): fixed filepos problem
1099 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
1100 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
1101 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
1102 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
1103 cleaned up. (coff_write_object_contents) cleaned up.
1105 * ecoff.c: Totally different. Now supports ecoff fully.
1107 * icoff.c: fixed problems in relocation callout.
1109 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
1111 * m68kcoff.c: updated target vector.
1113 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
1114 choose_reloc_size. (sunos4_write_object_contents) now calls
1115 choose_reloc_size so outputs relocs correctly, also calculates the
1116 size of the sections correctly.
1120 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1122 Merge Per Bothner's changes to modularize BFD a.out a bit.
1124 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
1125 * ieee.c: Cast enums to int before comparing them, for brain-
1127 * coff-code.h: Remove coff_get_section_contents, and use the
1128 generic one instead.
1130 * aout.c: Derive new module from sunos.c, containing generic
1131 support code for all kinds of a.out files.
1133 * sunos.c: Remove all code that goes in aout.c. Split out
1134 machine dependent followup in sunos4_object_p into
1135 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
1136 and redefine only the names we CHANGE, not all the names. Drop
1137 the little-endian vector, and rename the vector as sunos4 rather
1140 * b.out.c: Use aout.c routines for most of the work. Slight
1141 changes for the new regime. Remove close_and_cleanup and
1142 get_section_contents in favor of generics. New transfer vector
1145 * newsos.c: New support for Sony NEWS, another a.out format.
1147 * ecoff.c: Remove close_and_cleanup. New tvec regime.
1148 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
1149 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
1151 * opncls.c (bfd_close): Call format-dependent write_contents
1152 routine, if writing, before calling target-dependent
1153 close_and_cleanup routine (which is now always generic, I think).
1154 * srec.c: Use bfd_alloc instead of malloc. Remove
1155 close_and_cleanup and move code from it to
1156 srec_write_object_contents. Add write_contents to tvec.
1157 * targets.c: Remove a.out little vector, replace a.out big
1158 vector with SunOS vector. FIXME: Need Vax support again now.
1160 * libbfd.h: Add write_contents format-dependent-vector to the
1161 bfd_target vector. Supply a generic close_and_cleanup routine.
1162 * liba.out.h: Handle the new aout.c split. Add prototypes for
1163 all routines defined in aout.c. Rename "sunos" things to "aout"
1164 things. Add a few fields where needed for various formats.
1165 * Makefile.in: Add aout.c and newsos.c.
1167 * archive.c, ieee.c, oasys.c: Lint.
1169 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1172 changed forward declaration struct stat; to reduce warnings. Changed
1173 comment on bfd_h_<x>_x.
1175 * ../include/m68kcoff.h, ../include/intel-coff.h,
1176 ../include/m88k-bcs.h
1177 Now there are two incarnations of relocs, linenos and syments. One for
1178 internal digestion, and one full of char arrays for I/O. The original
1179 names have gone to detect errors.
1181 * Makefile.in, m68kcoff.c, targets.c
1182 Test new structure code with a 68k coff implementaion
1184 * coff-code.h, icoff.c, coffswap.c, libcoff.h
1185 Fixed all the places where there were problems with the size and
1186 alignments of structures on disk and structures in memory. #ifed out
1187 all the code in coffswap.c, since it should be done using the target
1190 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1192 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
1193 multiple reloc command.
1195 * sunos.c (sunos4_set_section_contents): Made it so that sections
1196 are always padded to their alignment size.
1198 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1200 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
1201 Clean up types and such (saber C problems).
1202 * ecoff.c: Clean up types and such. Remove routines that are
1203 not used. Fix up reading and swapping of shorts from files.
1205 Notes on bfd-0.5.2-patch1a, from Per Bothner:
1207 * a.out.vax.c: Remove two bogus "static" from prototypes.
1209 * ecoff.c: Got rid of lots of non-working junk (that had
1210 been copied directly from coff-code.h).
1211 Updated to be consistent with updates to icoff.c and coff-code.h.
1213 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
1214 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
1216 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
1217 but until the target_vector is automatically generated,
1218 it's as good as any. Note that the text offset is the only
1219 difference between NewsOS and SunOs (including magic numbers).
1220 (Most of the sunos_* routines should to renamed bsd_*
1221 and move to a bsd.c file. Then (and when the target_vector
1222 is automatically generated) it might make sense to create
1223 a separate Sony target.)
1225 * sysdep.h: Don't declare fread and fwrite. Causes trouble
1226 on some systems, and doesn't help on others.
1227 Similarly, only define X_OK if not already defined.
1229 * trad-core.c: Don't include sys/stat.h - at least
1230 on NewsOS 3, it has already been included.
1232 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1234 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
1235 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
1236 symbol tables if necessary when reading them in, so gdb can use
1237 them. Add "bfd_coff_" to the names so they won't conflict with
1238 names in calling programs. FIXME-soon: if coff-code.h is
1239 included in two BFD modules, this will cause duplicate
1240 definitions; the routines should be exported to a separate,
1241 common, module (probably along with a mess of other ones).
1243 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1245 Improve modtime support.
1247 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
1248 Remove #define for bfd_get_mtime. Remove gratuitous comment.
1249 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
1250 BUG: archive members still do not get correct mod times.
1252 Improve floating point support for core files.
1254 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
1255 (sunos4_core_file_p): Create a second registers section in the
1256 core file, called ".reg2", for the float registers.
1258 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1260 * many changes to improve archive handling; found a logic flaw in
1261 bfd_check_format which only just happened to work by cooncidence.
1263 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1265 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
1268 * bfd.h: changed type of udata in asymbol to void *, like it
1269 should be. Added bfd_reloc_dangerous enum member.
1271 * coff-code.h: Fixed it so that internally generated symbols get
1272 their values relocated correctly in all cases. Removed calls to
1275 * icoff.c: Not understanding the destination symbol of a reloc is
1276 not a failure any more, just 'dangerous'. This allows linking of
1277 b.out and coff images.
1279 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
1283 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1285 * sunos.c (translate_to_native_sym_flags): fixed
1286 sym_pointer->n_value so that symbols on the way out get their
1287 section relative values calculated correctly.
1289 * coff-code.h (mangle_symbols): fixed problem where tags were not
1290 being relocated for structs, enums, unions. Also various lints.
1292 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1294 * archive.c (get_elt_at_filepos): system_call_error returned
1297 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1299 * Resolve the use of no_error and system_call_error.
1300 The bfd library itself now will never set bfd_error to
1303 The code still needs to be combed to make sure all the error
1304 codes are correct. I suspect they are not always set correctly.
1306 * The names of all the messages have _ prepended because the sun
1307 bundled compiler can't distinguish from a macro which takes an
1308 argument and the same identifier in a non-macro context.
1310 * The reason for the above being that entry points which used to
1311 be trampoline functions are now just macros which expand to a
1312 direct call through the bfd's xfer vector.
1314 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
1315 must gas have its own version of everything (the gas version
1316 had the correct value)
1318 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1320 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
1321 properly support i960 architecture and output correct reloc stuff.
1323 * bfd.h: added prototype for bfd_printable_arch_mach, added
1326 * coff-code.h: Applied patches from chrisb to support i960
1327 architecture, zero relocs and swap them correcly and conditionally
1328 compiled the timestamp.
1330 * sunos.c: Made the default section alignment 2^3 so that doubles
1331 are done properly. Fixed the same reloc bug that was in b.out.c
1333 * sysdep.h: Now compiles on a Posix box
1335 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1337 * icoff.c: Fix comment on big-endian version.
1338 * coff-code.h: Make HAS_RELOC really work (it's backwards from
1339 F_RELFLG). Set F_AR32WR in output files if little endian
1342 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
1344 * archures.c fixed =/== typo
1346 * sunos.c added architecture stuff for output. Fixed
1347 bug where files where vma(data) != size(text)
1348 were processed wrong.
1350 * coff-code.h added a lint cast
1352 * (../include/a.out.sun4.h) fixed it so zmagic
1355 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
1357 * archive.c removed loads of includes, and fixed bug where string
1358 table didn't have a null at the end.
1360 * bfd.c fixed includes, added symbols argument to
1361 canonicalize_reloc entry point.
1363 * libbfd.c fixed includes and added some lint patches.
1365 * targets.c added both sorts of intel coff.
1367 * b.out.c fixed included, changed was the canonical

1373 * opncls.c added chmod+xing for files with EXEC_P set.
1375 * sunos.c fixed includes. Changed default section
1376 alignement to words. Fixed relocation stuff to work with
1379 * bfd.h various new types added, prototype for new
1380 reloc calls, changed bfd->iostream to a void *
1381 to including files don't need stdio.h.
1383 * libcoff.h added conversion table to tie relocs to
1388 * coff-code.h fixed includes. Added code to support
1389 big and little endian formats. Various lints. Better
1390 processing of symbols. Changed reloc stuff to new
1393 * libbfd.h fixed includes
1396 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
1398 * bfd.h changed name of alignment entry in sec_struct to
1399 alignment_power, because of conflicting uses within bfd.
1400 Now it should be obvious that it's a 2**n alignment
1401 specifier. Removed start_pad, end_alignment, block, minsize,
1402 output_file_alignment, subsection_alignment and original_vma fields.
1403 Added align_power() macro. Fixed bfd_section_alignment
1404 acessor macros. Added bfd_symbol_same_target macro.
1406 * b.out.c (b_out_write_object_contents) fixed to use
1407 new alignment member. Fixed (callj_callback) to use section
1408 relative symbols properly.
1410 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
1411 Fixed (translate_from_native_sym_flags) to correctly make
1412 symbols section relative.
1414 * bfd.c (bfd_errmsg) fixed various enum cast problems.
1415 (bfd_make_section) took out initialization of obsolete members.
1416 (bfd_print_symbol_vandf) added
1418 * opncls.c (bfd_create) created.
1420 * coff-code.h (coff_new_section_hook) took away refs
1421 to obsolete members. (make_a_section_from_file) added
1422 conversion between alignment types. (coff_symbol_from)
1423 added. (coff_count_linenumbers) only counts linenumbers
1424 if symbol is of coff-type. (coff_mangle_symbols) only
1425 heavily mangles symbols if symbol is coff-type.
1426 (coff_write_symbols) various lints. (coff_write_object_contents)
1427 various lints and modification for alignment conversion.
1428 (coff_slurp_relocs) fixed for use with new asection shape.
1430 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
1432 * archive.c lots of lint
1434 * b.out.c added callj relocation support, upgrated reloc howto.
1435 Fixed so that asymbol and reloc records are output
1438 * bfd.c lots of lint, support for new bfd entry point
1441 * bfd.h changed definition of asymbol to contain pointer to
1442 owning bfd, removed target dependencies.
1444 * cache.c took out print statements, put in BFD_ASSERT calls.
1446 * coff-code.h various lints, corrected linenumber output
1447 functionality. Added support for new style asymbols and
1448 bfd_print_symbol. Fixed so that asymbol and
1449 reloc records are handled correctly. Added timestamp.
1451 * icoff.c Added support for new howto shape.
1453 * liba.out.h Added support for new asymbol shape
1455 * libbfd.c various lints
1457 * libbfd.h various lints

1461 * sunos.c various lints. Added support for new asymbol shape
1462 and bfd_print_symbol.
1464 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
1466 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
1467 pointer lint. Added support for callj relocation. Fixed bug where
1468 the last 32 bytes of the text section were overwritten by data. Fixed bug
1469 where archives of b.out didn't work due bfd_slurp_extended_name_table
1472 * sunos.c added support for n_other field. Braced the howto table so
1473 that it won't be affected by any lengthing of the howto struct typedef.
1476 * bfd.h added support for n_other field, added special_function
1477 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
1480 * bfd.c upgraded bfd_perform_relocation, various lints.

1484 * ChangeLog: Started ChangeLog for BFD.
1485 * ToDo: Create file for suggestions.
1487 * Makefile: Support easy loading into Saber C.
1488 Add dependencies for icoff.o and bcs88kcoff.o.
1489 Rename coff.c to coff-code.h. Change callers.
1491 * bfd.c (bfd_check_format): Allow the check_format routines
1492 to return the desired target vector, rather than just a Boolean.
1493 bfd.h (bfd_check_format): Change function pointer return type.
1494 archive.c (bfd_generic_archive_p): change callee.
1495 b.out.c (b_out_little_object_p, b_out_big_object_p,
1496 b_out_real_object_p): change callee.
1497 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
1498 in check_format transfer vectors that need a filler.
1499 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
1500 bcs88kcoff.c: change callee.
1501 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
1502 icoff.c: change callee.
1503 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
1505 * libbfd.c (zalloc): It should actually zero the storage!
1506 This was commented out for some reason.
1508 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
1509 This is so callers can avoid <stdlib.h> which doesn't exist
1512 * bfd.c (map_over_sections): Add debugging code, since I
1513 noticed the section count for sunos core files was bad, but only
1514 GDB had detected the problem.
1515 (bfd_set_section_lineno_size, bfd_set_section_linenos,
1516 bfd_get_section_linenos): Remove obsolete functions.
1517 (bfd_apply_relocations): Use longs, not ints, for the math.
1519 * bfd.h: Declare enum boolean and struct bfd_target as well
1520 as typedefs for them. Remove obsolete
1521 bfd_get_section_lineno_size.
1523 * cache.c: Make the "fdopen" support work. Keep better track
1524 of how many files are open. Centralize the opening of files
1525 and be sure bfd_open[rw] actually try to open the file. Evade
1526 linked list initialization problems.
1528 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
1530 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
1532 * cplus-dem.c: Delete file, since it is not part of BFD.
1534 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
1535 (bfd_openr, bfd_openw): Actually open the file, give error now.
1537 * sunos.c (sunos4_core_file_p): Set section count.
1538 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
1539 obsolete definitions.
1540 (_write_symbol_table): Initialize <idx> counter.
1541 (foop): Eliminate debugging code.
