1 Sat Dec 7 07:22:09 1991 John Gilmore (gnu at cygnus.com)
3 * coffcode.h, srec.c: Lint.
5 Fri Dec 6 22:58:48 1991 K. Richard Pixley (rich at rtl.cygnus.com)
7 * Makefile.in: install using INSTALL_DATA, added standards.text
10 * configure.in: mark directory as target dependent. configure
11 nows works in objdir always so make file existence checks
14 Thu Dec 5 22:46:19 1991 K. Richard Pixley (rich at rtl.cygnus.com)
16 * Makefile.in: idestdir and ddestdir go away. Added copyrights
17 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
18 and mandir now keyed off datadir by default.
20 Wed Dec 4 10:14:17 1991 Steve Chamberlain (sac at rtl.cygnus.com)
22 * aoutf1.h (sunos_<size>_object_p, sunos4_callback): moved the
23 computation of arch and machine type so it's worked out before
24 some_aout_object_p is called.
25 * aoutx.h: (some_aout_object_p): don't set arch and mach to
27 * archures.c: add extra field 'section_align_power' to hold
28 default section alignment in object files.
29 * cpu-a29k.c, cpu-h8300.c, cpu-i386.c, cpu-i960.c, cpu-m68k.c,
30 cpu-m88k.c, cpu-mips.c, cpu-rs6000.c, cpu-sparc.c, cpu-vax.c:
31 initialize the new field.
32 * bout.c (b_out_callback): replace the text size, since aout
34 * aoutx.h: Documentation in the new style
36 Wed Dec 4 02:00:30 1991 John Gilmore (gnu at cygnus.com)
38 * bfd.c (bfd_get_mtime): Don't cache mtime any more; only
39 use the saved value if mtime_set is already set (intended
40 for archive files, though apparently not used yet).
42 Tue Dec 3 22:54:50 1991 John Gilmore (gnu at cygnus.com)
44 * targets.c: Revise comments about how to configure the target
45 vector, to match reality. Remove mention of obsolete methods.
46 Remove long lists of capitalized macros that turn into the same
47 thing in lowercase. Normal vector simply lists all known
48 lowercase xvec names; all other cases are handled by SELECT_VECS.
50 * config/mt-i386-coff: Set DEFAULT_VECTOR to real identifier,
53 * config/mt-i960-{coff,bout}: Use SELECT_VECS to make a short
54 list of supported targets.
56 Tue Dec 3 14:06:15 1991 Per Bothner (bothner at cygnus.com)
58 * archive.c (bsd_write_armap): The pad byte sometimes added to
59 the string table in a __.SYMDEF member is now
60 counted as part of the size of the string table.
61 This is compatible with the old ranlib, as well as Sun's.
63 Tue Dec 3 10:53:30 1991 Steve Chamberlain (sac at rtl.cygnus.com)
65 * srec.c: Rewrote to fix many bugs; now gets the record type
66 right, doesn't choke on input, sets the start address in an S9 and
67 fills in the filename on an S0.
69 Sat Nov 30 21:19:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
71 * cpu-h8300.c: Add support for MEMIND addressing mode
73 * coff-a29k.c: defined RELOC_PROCESSING to take the #ifdef out of
75 * coffcode.h: use the new macro if available
77 * elf.c (elf_corefile_note): cast malloc to avoid warning.
78 * Makefile.in: Fixed dependencies due to file rename
80 * aout-encap.c, aoutf1.h, aoutx.h, archive.c, bout.c, coff-a29k.c,
81 coff-h8300.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
82 coff-mips.c, coff-rs6000.c, cpu-h300.c, elf.c, i386aout.c,
83 newos3.c, stab-syms.c, syms.c: All these files have had their
84 #includes altered to point to the new places.
86 Fri Nov 29 20:04:49 1991 Fred Fish (fnf at cygnus.com)
88 * config/mh-i386v4, config/mh-i386-elf, hosts/h-i386v4.h: New files.
90 * configure.in: Add vendor "ncr" as supported per-target vendor.
91 Add svr4 case for i386 per-host case.
93 * elf.c (elf_object_p, elf_core_file_p): Add missing "break" to
96 Fri Nov 29 12:16:51 1991 Per Bothner (bothner at cygnus.com)
98 * syms.c (bfd_decode_symclass): Return 'A'
99 for symbols that are both absolute and global.
100 * archive.c (bfd_special_undocumented_glue): Return NULL
101 if bfd_ar_hdr_from_filesystem returns NULL.
103 Tue Nov 26 09:10:55 1991 Steve Chamberlain (sac at cygnus.com)
105 * Makefile.in: added coff-h8300
106 * configure.in: now h8 is a coff target
107 * cpu-h8300.c: fix various disassembly problems
108 * libcoff.h: took out some code which has been #0ed for a long
110 * targets.c: added h8 coff
111 * coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c
112 added new macro RTYPE2HOWTO to take a load of #ifdefs out of
114 * coffcode.h: Started to change the way machine dependencies are
115 handled, from the nest of #ifdefs to macros defined in the
116 including coff-<foo>.c
118 Fri Nov 22 08:11:42 1991 John Gilmore (gnu at cygnus.com)
120 * aoutx.h (some_aout_object_p): Set the `executable' bit
121 if the entry point is contained in the text segment, even if the
122 text segment is at location 0.
124 * coff-mips.c, coffcode.h: Peter Schauer's patch to kludge in
125 nonstandard MIPS sections (.rdata, .sdata, etc).
127 * aoutx.h, bfd.c, coffcode.h, ieee.c, oasys.c, targets.c: CONST lint.
128 * libbfd-in.h, libbfd.h, aoutx.h, coffcode.h, elf.c, libaout.h:
129 Rename ALIGN to BFD_ALIGN to avoid conflict with BSD <sys/param.h>.
131 * host-aout.c, trad-core.c: Fix write_armap prototypes. Lint.
133 Thu Nov 21 19:56:40 1991 Per Bothner (bothner at cygnus.com)
135 * stab-syms.c, syms.c: Moved bfd_stab_name() and bfd_stab_names[]
136 from syms.c to new file stab-syms.c. Also, since GNU extended
137 type codes such as N_SETT are no longer in ../include/stab.def,
138 include them manually.
139 * stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
140 bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
141 * libaout.h: Added prototype for aout_stab_name().
142 * Makefile.in: Update Makefile for new stab-syms.[co].
144 Thu Nov 21 11:50:49 1991 John Gilmore (gnu at cygnus.com)
146 * libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this
147 rather complicated seeming problem. Eliminate LOGICAL_ versions,
148 just make N_XXX work by excluding the header from the text segment.
149 * aoutx.h: Fix comments to match.
151 Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
153 * libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
154 LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
155 for the "logical" text segment (i.e. never consider the exec
156 header to be part of the text segment). This change is
157 needed for consistency with various other parts of bfd and ld.
158 * aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
159 and move calculation of obj_textsec(abfd)->size to libaout.h.
160 * bfd-in.h: Removed bogus ';'.
162 * Makefile.in: Add MINIMIZE flag to select lean
163 or bloated target_vector.
164 * targets.c: Use new MINIMIZE macro, and add trad_core if needed.
165 * newsos3.c: Fixes to ../include/aout64.h remove need
166 for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
168 Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
170 * aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h
171 handle both little and big-endian targets, with little
172 the default unless TARGET_IS_BIG_ENDIAN_P is defined.
173 * host-aout.c: Add FIXME note.
175 Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
177 * targets.c: Make the default target_vector contain
178 just &DEFAULT_VECTOR. This makes executables a lot smaller.
179 Old behavior can be gotten by defining ALL_TARGETS.
180 * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
181 Factored out common code into new file aout-target.h.
182 Saves a lot of duplicate code for a.out variants.
184 Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)
186 Get 'make headers' to work when configured with +subdirs.
187 * Makefile.in: Add $(subdir) to docdir path.
188 * doc/Makefile.in (protos): Add $(srcdir) prefix
189 to name of sed scripts.
191 Thu Nov 14 19:49:10 1991 Per Bothner (bothner at cygnus.com)
193 * aoutx.h (NAME(aout,print_symbol)): Fix thinko.
194 * syms.c (bfd_stab_names): Turn on new GNU_EXTRA_STABS macro
195 to include names of N_SETT etc.
197 Thu Nov 14 19:11:13 1991 Fred Fish (fnf at cygnus.com)
199 * elf.c: Add minimal support for ELF symbol tables. Generates
200 canonical bfd symbol tables from ELF symbol tables. Change the
201 name of some functions from bfd_<name> to elf_<name>.
203 * syms.c: Trivial fix to comment to remove a redundant "to".
205 Wed Nov 13 17:02:01 1991 John Gilmore (gnu at cygnus.com)
207 * coff-{i386,m68k,m88k}.c: Change name of file format to standard
208 form that GDB recognizes as COFF.
210 Wed Nov 13 09:09:41 1991 Steve Chamberlain (sac at cygnus.com)
212 * ieee.c (ieee_object_p): cast NULL correctly.
213 * configure.in: added harris host
215 * coff-a29k.c: Lots of changes, most from David Wood.
217 Tue Nov 12 07:21:41 1991 John Gilmore (gnu at cygnus.com)
219 * coff-m88k.c (coff_write_armap): Just #undef it.
221 Mon Nov 11 20:30:18 1991 Steve Chamberlain (sac at cygnus.com)
223 * Makefile.in: standardize on MINUS_G to disable debugging
224 * coff-m88k.c: create coff armaps instead of bsd ones.
225 * opncls.c (bfd_close_all_done), (bfd_close): Mask out random bits
228 Mon Nov 11 19:07:32 1991 Fred Fish (fnf at cygnus.com)
230 * elf.c: Additions to support ELF format core files.
231 * config/mh-amix: Add -DHAVE_PROCFS to HDEFINES, since host
232 has support for /proc (all the include files in particular).
234 Mon Nov 11 18:36:47 1991 Per Bothner (bothner at cygnus.com)
236 * aoutx.h (NAME(aout,find_nearest_line)): Handle the case
237 of two N_SO stabs, one for directory, and one for filename.
239 * bfd-in.h (print_vma): Factor out duplicate definition.
241 Exit a little more gracefully when malloc returns NULL.
242 * libbfd.c: New function bfd_xmalloc (malloc wrapper).
243 * opncls.c, syms.c, bout.c, aoutx.h: Replace malloc by bfd_xmalloc.
244 * libbfd.h: Rre-generated due to libbfd.c update.
246 Sat Nov 9 13:45:01 1991 Fred Fish (fnf at cygnus.com)
248 * config/mt-m68k-elf: Define DEFAULT_VECTOR as elf_big_vec.
250 * elf.c (elf_object_p): Don't try to create a bfd section for
251 the first ELF section header. It is just a placeholder.
253 Sat Nov 9 03:04:26 1991 John Gilmore (gnu at cygnus.com)
255 * coff-rs6000.c, config/mh-rs6000: Make it work on archive and
256 core files, when compiling native.
257 * hosts/h-rs6000.h: Define FASCIST_FDOPEN for bfd_fdopenr.
259 FIXME: The aoutf1.h change below needs to be reversed back
262 Thu Nov 7 11:03:55 1991 Steve Chamberlain (sac at rtl.cygnus.com)
264 * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
265 manipulation of lnno fields in lineno structs in a coff-<f>.h
266 independent way. Override it in coff-<f>.h to your favourite
267 number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
268 (coff_swap_lineno_out): modified to use the new macros.
270 Mon Nov 4 11:38:33 1991 Steve Chamberlain (sac at cygnus.com)
272 * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
273 unknown arch when the magic number doesn't specify the
274 architecture, since some OSs (eg old sun3s) don't set the number, and
275 020 is probably the right answer anyway.
277 Sun Nov 3 12:07:08 1991 Per Bothner (bothner at cygnus.com)
279 * hosts/h-news.h, hosts/h-rtbsd.h:
280 Get rid of MISSING_VFPRINTF, since libiberty provides one.
281 * bfd-in.h (bfd_print_symbol_type_hopw enum): Add new option
282 bfd_print_symbol_nm, for use by nm.
283 * aoutx.h (NAME(aout,print_symbol)): Add code for new
284 bfd_print_symbol_nm option, to print in nm format.
285 * coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
286 oasys.c (oasys_print_symbol): Provide stub implementations
287 for bfd_print_symbol_nm.
288 * syms.c: New function bfd_decode_symclass, used by nm printer.
289 New function bfd_stab_name to look up string name of stab code.
291 Sat Nov 2 14:26:03 1991 Steve Chamberlain (steve at cygnus.com)
293 * Makefile.in: Added ctor.c
294 * archures.c (bfd_default_arch_struct) added
295 bfd_default_reloc_type_lookup.
296 * coffcode.h: removed a load of #if 0ed code.
297 (coff_compute_file_section_positions): now works out the section
298 alignment and size correctly in all cases.
299 (coff_get_symtab): looks for constructor symbols and calls the
300 right function when they're found. (coff_canonicalize_reloc):
301 knows when a section is full of constructors and does the right
303 * cpu-m88k.c: Added default_reloc_type lookup to the architecture
305 * libbfd-in.h: (bfd_default_reloc_type_lookup) defun added.
306 * libcoff.h: removed #if 0ed code
307 * reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
308 arch independent constructor relocation type.
309 (bfd_reloc_type_lookup): removed the comment "this will go away"
310 since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
311 reloc which is used when BFD_RELOC_CTOR falls through to give a
312 default 32bit reloc for constructors.
313 (bfd_default_reloc_type_lookup): added.
314 * aoutf1.h: fixed SEGMENT_SIZE typo.
316 Thu Oct 31 18:23:06 1991 John Gilmore (gnu at cygnus.com)
318 * coff-rs6000.c: Change name to "aixcoff-rs6000", to avoid
319 matching prefix "coff".
320 * coffcode.h (coff_swap_aux_in, coff_swap_aux_out): Handle
321 rs/6000 csect records.
323 Sun Oct 27 16:56:58 1991 Steve Chamberlain (steve at cygnus.com)
325 * coff-m88k.c, targets.c: change name of m88k_bcs to m88kbcs
326 * configure.in: add motorola delta88 cases
327 * libbfd.h, libbfd-in.h, archive.c, ieee.c, elf.c, srec.c: fix
328 write_armap prototype
329 * libbfd.c: add doc on bfd_write_bigendian_4byte_int
331 Fri Oct 25 02:48:19 1991 John Gilmore (gnu at cygnus.com)
333 * Rename COFF-related files in `coff-ARCH.c' form.
334 coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
335 coff-mips.c, coff-rs6000.c to be exact.
337 * Makefile.in: Only supply TARGET_DEFAULTS to targets.c, reducing
339 * config/mt-*: Ditto.
341 Thu Oct 24 22:40:07 1991 John Gilmore (gnu at cygnus.com)
343 RS/6000 support, by Metin G. Ozisik, Mimi Phûông-Thåo Võ, and
344 John Gilmore. Archive support from Damon A. Permezel.
346 * Makefile.in: Add cpu-rs6000.c and rs6000coff.c.
347 * configure.in: Add rs6000 case.

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

817 * bout.c, icoff.c, ieee.c, libbfd.c, oasys.c: gcc -O -W lint.
819 Wed Sep 4 00:44:52 1991 John Gilmore (gnu at cygint.cygnus.com)
821 Allow GDB to patch object files.
823 * aoutf1.h (sunos_core_file_p): Set SEC_HAS_CONTENTS on all sections.
824 * trad-core.h (trad_unix_core_file_p): Ditto.
825 * aoutx.h (aout_set_section_contents): On first output, check
826 abfd->direction and complain if erroneous.
828 * Makefile.in: Add crude dependencies.
830 Tue Sep 3 13:46:19 1991 Steve Chamberlain (steve at cygint.cygnus.com)
832 * config/* aoutx.h configure* shortened all the h/tmake-xxxx
833 to h/t-xxxx files so that everything will work on System V.
835 Fri Aug 23 13:51:06 1991 John Gilmore (gnu at cygint.cygnus.com)
837 * aoutx.h: Add information on host-aout.c and how to configure
838 to use it, to the manual.
839 * configure.in: Tix typo.
840 * ecoff.c: If compiling for DEC3100, use trad_unix core files,
841 else dummy out the core file support.
842 * trad-core.c (trad_unix_core_file_p): If HOST_DATA_START_ADDR is
843 specified, use it to locate the data section.
844 * coffcode.h (coff_write_symbols): Declare buffer as bfd_bytes
845 rather than as chars (lint).
847 Thu Aug 22 22:20:19 1991 Stu Grossman (grossman at cygint.cygnus.com)
849 * aoutx.h, coffcode.h: saberized.
851 Thu Aug 22 11:27:06 1991 Roland H. Pesch (pesch at cygint.cygnus.com)

858 Wed Aug 21 19:13:22 1991 John Gilmore (gnu at cygint.cygnus.com)
860 * trad-core.c (trad_unix_core_file_p): Use HOST_TEXT_START_ADDR,
861 etc, rather than TEXT_START_ADDR.
862 * host-aout.c: Remove #if 0 around whole thing.
863 Update to modern (32/64-bit) a.out naming conventions.
864 Include a large chunk of ../include/a.out.gnu.h to get macros that
865 are not defined by the system include files.
866 (host_aout_{32,64}_write_object_contents): Use the WRITE_HEADERS
867 macro used by the other a.out implementations.
868 * Makefile.in: Give dependencies to OPTIONAL_BACKENDS.
870 Wed Aug 21 14:33:06 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
872 * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of
873 texdoc and psdoc; make these depend on generated .texi's
875 * scanit, (new) unPROTO: turn PROTO macros into ANSI declarations in
878 * bfd.c, reloc.c, syms.c: minor spelling/wording fixes in doc
881 * Makefile.in, awkscan-ip, awkscan-p, intobfd,
882 libbfd.h, libcoff.h, tolibcoff; new bfd-in.h, libbfd-in.h,
883 libcoff-in.h: (a) use separate files for invariant parts of bfd.h,
884 libbfd.h, and libcoff.h; (b) in generated parts of same, use less
885 obtrusive marks indicating .c origins.
887 * bfd.texinfo: generalize most references to linker
889 Tue Aug 20 15:18:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)

914 * syms.c: added BSF_CONSTRUCTOR, BSF_WARNING and BSF_INDIRECT
915 flags. (bfd_print_symbol_vandf) now knows what to do with the
918 * aoutx.h: made translate_from_native_sym_flags and
919 translate_to_native_sym_flags produce the above flags.
922 Wed Jul 31 09:53:52 1991 John Gilmore (gnu at cygint.cygnus.com)
924 * all files: update copyright notices for GPL version 2.
925 Install header comments and attribute most modules to their
926 authors. BFD's name is now officially "Binary File Descriptor",
927 so remove any conflicting pejoratives.
928 archures.h: Consists solely of comments; remove it.
930 Fri Jul 26 18:11:34 1991 Steve Chamberlain (steve at cygint.cygnus.com)

945 * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
946 29k coff by David Wood (wood@lab.ultra.nyu.edu).
948 Thu Jul 4 09:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
950 * Everything: created some new files, core.c format.c, reloc.c,
951 section.c and syms.c to split the functionality a bit better.
952 Cleaned up the rest of the files a bit, and added some
956 Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu)
958 * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
959 really takes 3 arguments, patched code and ammended prototypes.
961 Fri Jun 14 13:19:40 1991 Steve Chamberlain (steve at cygint.cygnus.com)
963 * ../include/bfd.h (struct bfd_target): Added new field
964 "align_power_min" which contains the minimum alignment for a
965 section. This is used in coff_new_section_hook. The field
966 insertion necessitates an update of all backends..
968 * aoutf1.h jump table field inserted
970 * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
973 * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
974 table field inserted.
976 * coffcode.h(just about everything) Now patches up symbol tables
977 using a different mechanism. The Intel major bug has been fixed,
978 and the linker can self host on the Aviion and be debugged with
981 * ecoff.c: new include and jump table patch, i386coff.c: new
982 include and jump table patch, icoff.c: new include and jump table
983 patch, ieee.c: can now read archives containing ieee modules.,
984 libcoff.h: added (combined_entry_type), libieee.h: uped max
985 sections to 20, m68kcoff.c: new include and jump table patch,
986 m88kbcs.c: new include and jump table patch, oasys.c: various bugs
987 fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.
988 srec.c: jump table patch. trad-code.c fixed #IF typeo
990 Fri Jun 7 12:35:46 1991 Sean Fagan (sef at cygint.cygnus.com)
992 * coffcode.h (coff_swap_aux_in): added else case to deal with
993 filenames less than 9 characters.
996 Thu Jun 6 18:27:38 1991 Steve Chamberlain (steve at cygint.cygnus.com)
998 * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
1000 * srec.c: now allows any number of sections to be created in a
1001 file. Outputs addresses of the right length.
1003 Thu May 30 15:30:10 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1005 * bfd.c (bfd_check_format): Fixed problem where when a defaulted
1006 target didn't match, the format got set to the attempted match,
1007 breaking a future test.
1009 *../include/i386coff.h : fixed typo in type field with size
1011 * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
1012 support in the jump table for the swapping routines exported to
1013 gdb. Now gdb works with the 386.
1015 Tue May 28 17:21:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1017 * Merge in changes from gdb-3.95 release.
1018 Makefile.in: Allow hmake and tmake files to add OFILES.
1020 bfd.c: support specific targets as well as searching. When
1021 searching, take default target in preference to others.
1023 ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
1024 liba.out.h: Don't hard-code file offsets; use N_ macros for them.
1025 libbfd.h: Support specific targets as well as searching.
1026 opncls.c: Support specific targets as well as searching.
1027 targets.c: Search is short-circuited if default target matches.
1028 liboasys.c, libieee.c: Undo bothner changes that make macros
1029 work to the left of assignment, but which depend on the
1030 representations of different pointer types being the same.
1032 Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1034 * i386coff.c: created.
1035 * coffcode.h: added support for 386.
1036 * Makefile.in: added support for 386.
1037 * ../include/i386coff.h: created
1039 Wed May 22 07:26:38 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1041 * coffcode.h: removed all put_x_<sizes>
1042 * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
1046 Tue May 21 08:58:58 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1048 * opncls.c: Changed obstack_chunk_alloc use xmalloc
1050 Mon May 20 17:12:17 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1052 * everything: Removed sysdep.h from bfd.h and put back into files
1053 from which it was split out. Now 64 bit version is built with a
1054 -DHOST_64_BIT="long long" on the compile line.
1057 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1059 Changed all the [get|put][name] routines to use [get|put]_[size
1062 Put in support for 64 bit work. Now two versions of bfd may be
1063 generated, according to the state of TARGET_64_BIT, one which is
1064 32 bit only, and one which is 64/32 bits.
1065 Created new back end 'demo64' to test 64 bit functionality.
1067 Renamed some files to work on DOS.
1069 * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
1070 64bit transfer * icoff.c: added 64bit transfer * ieee.c: name
1071 chage, 64 bit transfer. * liba.out.h: Split out common code from
1072 sunos and newsos into liba.out. Name changes and prototype mods. *
1073 libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
1074 prototypes for new functions. * libcoff.h: lint * libieee.h: make
1075 work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
1076 change and 64bit stuff.* newsos3.c: common code removed, new jump
1077 table. * oasys.c: Name change * opncls.c: Portability fixes *
1078 srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
1079 Added demo * aout32, aout64.c include aoutx.h * bout.c: used to
1080 be called b.out.c * coffcode.h: used to be called coff-code.h, now
1081 64bit ized. * demo64.c: 64 bit a.out back end
1087 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1089 * libieee.h: Make ieee_data and ieee_ar_data macros usable
1090 on LHS of assignment, even when using old compilers.
1091 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
1092 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
1093 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
1094 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
1095 * targets.c: Add declaration of newsos3_vec.
1098 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1100 * aout.c: fixxed some of the problems with filepos calculation.
1101 (swap_ext_reloc): fixed problem with creation of relocs.
1102 (aout_set_section_contents): fixed filepos problem
1104 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
1105 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
1106 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
1107 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
1108 cleaned up. (coff_write_object_contents) cleaned up.
1110 * ecoff.c: Totally different. Now supports ecoff fully.
1112 * icoff.c: fixed problems in relocation callout.
1114 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
1116 * m68kcoff.c: updated target vector.
1118 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
1119 choose_reloc_size. (sunos4_write_object_contents) now calls
1120 choose_reloc_size so outputs relocs correctly, also calculates the
1121 size of the sections correctly.
1125 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1127 Merge Per Bothner's changes to modularize BFD a.out a bit.
1129 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
1130 * ieee.c: Cast enums to int before comparing them, for brain-
1132 * coff-code.h: Remove coff_get_section_contents, and use the
1133 generic one instead.
1135 * aout.c: Derive new module from sunos.c, containing generic
1136 support code for all kinds of a.out files.
1138 * sunos.c: Remove all code that goes in aout.c. Split out
1139 machine dependent followup in sunos4_object_p into
1140 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
1141 and redefine only the names we CHANGE, not all the names. Drop
1142 the little-endian vector, and rename the vector as sunos4 rather
1145 * b.out.c: Use aout.c routines for most of the work. Slight
1146 changes for the new regime. Remove close_and_cleanup and
1147 get_section_contents in favor of generics. New transfer vector
1150 * newsos.c: New support for Sony NEWS, another a.out format.
1152 * ecoff.c: Remove close_and_cleanup. New tvec regime.
1153 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
1154 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
1156 * opncls.c (bfd_close): Call format-dependent write_contents
1157 routine, if writing, before calling target-dependent
1158 close_and_cleanup routine (which is now always generic, I think).
1159 * srec.c: Use bfd_alloc instead of malloc. Remove
1160 close_and_cleanup and move code from it to
1161 srec_write_object_contents. Add write_contents to tvec.
1162 * targets.c: Remove a.out little vector, replace a.out big
1163 vector with SunOS vector. FIXME: Need Vax support again now.
1165 * libbfd.h: Add write_contents format-dependent-vector to the
1166 bfd_target vector. Supply a generic close_and_cleanup routine.
1167 * liba.out.h: Handle the new aout.c split. Add prototypes for
1168 all routines defined in aout.c. Rename "sunos" things to "aout"
1169 things. Add a few fields where needed for various formats.
1170 * Makefile.in: Add aout.c and newsos.c.
1172 * archive.c, ieee.c, oasys.c: Lint.
1174 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1177 changed forward declaration struct stat; to reduce warnings. Changed
1178 comment on bfd_h_<x>_x.
1180 * ../include/m68kcoff.h, ../include/intel-coff.h,
1181 ../include/m88k-bcs.h
1182 Now there are two incarnations of relocs, linenos and syments. One for
1183 internal digestion, and one full of char arrays for I/O. The original
1184 names have gone to detect errors.
1186 * Makefile.in, m68kcoff.c, targets.c
1187 Test new structure code with a 68k coff implementaion
1189 * coff-code.h, icoff.c, coffswap.c, libcoff.h
1190 Fixed all the places where there were problems with the size and
1191 alignments of structures on disk and structures in memory. #ifed out
1192 all the code in coffswap.c, since it should be done using the target
1195 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1197 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
1198 multiple reloc command.
1200 * sunos.c (sunos4_set_section_contents): Made it so that sections
1201 are always padded to their alignment size.
1203 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1205 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
1206 Clean up types and such (saber C problems).
1207 * ecoff.c: Clean up types and such. Remove routines that are
1208 not used. Fix up reading and swapping of shorts from files.
1210 Notes on bfd-0.5.2-patch1a, from Per Bothner:
1212 * a.out.vax.c: Remove two bogus "static" from prototypes.
1214 * ecoff.c: Got rid of lots of non-working junk (that had
1215 been copied directly from coff-code.h).
1216 Updated to be consistent with updates to icoff.c and coff-code.h.
1218 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
1219 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
1221 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
1222 but until the target_vector is automatically generated,
1223 it's as good as any. Note that the text offset is the only
1224 difference between NewsOS and SunOs (including magic numbers).
1225 (Most of the sunos_* routines should to renamed bsd_*
1226 and move to a bsd.c file. Then (and when the target_vector
1227 is automatically generated) it might make sense to create
1228 a separate Sony target.)
1230 * sysdep.h: Don't declare fread and fwrite. Causes trouble
1231 on some systems, and doesn't help on others.
1232 Similarly, only define X_OK if not already defined.
1234 * trad-core.c: Don't include sys/stat.h - at least
1235 on NewsOS 3, it has already been included.
1237 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1239 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
1240 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
1241 symbol tables if necessary when reading them in, so gdb can use
1242 them. Add "bfd_coff_" to the names so they won't conflict with
1243 names in calling programs. FIXME-soon: if coff-code.h is
1244 included in two BFD modules, this will cause duplicate
1245 definitions; the routines should be exported to a separate,
1246 common, module (probably along with a mess of other ones).
1248 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1250 Improve modtime support.
1252 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
1253 Remove #define for bfd_get_mtime. Remove gratuitous comment.
1254 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
1255 BUG: archive members still do not get correct mod times.
1257 Improve floating point support for core files.
1259 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
1260 (sunos4_core_file_p): Create a second registers section in the
1261 core file, called ".reg2", for the float registers.
1263 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1265 * many changes to improve archive handling; found a logic flaw in
1266 bfd_check_format which only just happened to work by cooncidence.
1268 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1270 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
1273 * bfd.h: changed type of udata in asymbol to void *, like it
1274 should be. Added bfd_reloc_dangerous enum member.
1276 * coff-code.h: Fixed it so that internally generated symbols get
1277 their values relocated correctly in all cases. Removed calls to
1280 * icoff.c: Not understanding the destination symbol of a reloc is
1281 not a failure any more, just 'dangerous'. This allows linking of
1282 b.out and coff images.
1284 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
1288 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1290 * sunos.c (translate_to_native_sym_flags): fixed
1291 sym_pointer->n_value so that symbols on the way out get their
1292 section relative values calculated correctly.
1294 * coff-code.h (mangle_symbols): fixed problem where tags were not
1295 being relocated for structs, enums, unions. Also various lints.
1297 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1299 * archive.c (get_elt_at_filepos): system_call_error returned
1302 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1304 * Resolve the use of no_error and system_call_error.
1305 The bfd library itself now will never set bfd_error to
1308 The code still needs to be combed to make sure all the error
1309 codes are correct. I suspect they are not always set correctly.
1311 * The names of all the messages have _ prepended because the sun
1312 bundled compiler can't distinguish from a macro which takes an
1313 argument and the same identifier in a non-macro context.
1315 * The reason for the above being that entry points which used to
1316 be trampoline functions are now just macros which expand to a
1317 direct call through the bfd's xfer vector.
1319 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
1320 must gas have its own version of everything (the gas version
1321 had the correct value)
1323 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1325 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
1326 properly support i960 architecture and output correct reloc stuff.
1328 * bfd.h: added prototype for bfd_printable_arch_mach, added
1331 * coff-code.h: Applied patches from chrisb to support i960
1332 architecture, zero relocs and swap them correcly and conditionally
1333 compiled the timestamp.
1335 * sunos.c: Made the default section alignment 2^3 so that doubles
1336 are done properly. Fixed the same reloc bug that was in b.out.c
1338 * sysdep.h: Now compiles on a Posix box
1340 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1342 * icoff.c: Fix comment on big-endian version.
1343 * coff-code.h: Make HAS_RELOC really work (it's backwards from
1344 F_RELFLG). Set F_AR32WR in output files if little endian
1347 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
1349 * archures.c fixed =/== typo
1351 * sunos.c added architecture stuff for output. Fixed
1352 bug where files where vma(data) != size(text)
1353 were processed wrong.
1355 * coff-code.h added a lint cast
1357 * (../include/a.out.sun4.h) fixed it so zmagic
1360 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
1362 * archive.c removed loads of includes, and fixed bug where string
1363 table didn't have a null at the end.
1365 * bfd.c fixed includes, added symbols argument to
1366 canonicalize_reloc entry point.
1368 * libbfd.c fixed includes and added some lint patches.
1370 * targets.c added both sorts of intel coff.
1372 * b.out.c fixed included, changed was the canonical
1375 * icoff.c added support for callj and big and little
1378 * opncls.c added chmod+xing for files with EXEC_P set.
1380 * sunos.c fixed includes. Changed default section
1381 alignement to words. Fixed relocation stuff to work with
1384 * bfd.h various new types added, prototype for new
1385 reloc calls, changed bfd->iostream to a void *
1386 to including files don't need stdio.h.
1388 * libcoff.h added conversion table to tie relocs to
1393 * coff-code.h fixed includes. Added code to support
1394 big and little endian formats. Various lints. Better
1395 processing of symbols. Changed reloc stuff to new
1398 * libbfd.h fixed includes
1401 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
1403 * bfd.h changed name of alignment entry in sec_struct to
1404 alignment_power, because of conflicting uses within bfd.
1405 Now it should be obvious that it's a 2**n alignment
1406 specifier. Removed start_pad, end_alignment, block, minsize,
1407 output_file_alignment, subsection_alignment and original_vma fields.
1408 Added align_power() macro. Fixed bfd_section_alignment
1409 acessor macros. Added bfd_symbol_same_target macro.
1411 * b.out.c (b_out_write_object_contents) fixed to use
1412 new alignment member. Fixed (callj_callback) to use section
1413 relative symbols properly.
1415 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
1416 Fixed (translate_from_native_sym_flags) to correctly make
1417 symbols section relative.
1419 * bfd.c (bfd_errmsg) fixed various enum cast problems.
1420 (bfd_make_section) took out initialization of obsolete members.
1421 (bfd_print_symbol_vandf) added
1423 * opncls.c (bfd_create) created.
1425 * coff-code.h (coff_new_section_hook) took away refs
1426 to obsolete members. (make_a_section_from_file) added
1427 conversion between alignment types. (coff_symbol_from)
1428 added. (coff_count_linenumbers) only counts linenumbers
1429 if symbol is of coff-type. (coff_mangle_symbols) only
1430 heavily mangles symbols if symbol is coff-type.
1431 (coff_write_symbols) various lints. (coff_write_object_contents)
1432 various lints and modification for alignment conversion.
1433 (coff_slurp_relocs) fixed for use with new asection shape.
1435 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
1437 * archive.c lots of lint
1439 * b.out.c added callj relocation support, upgrated reloc howto.
1440 Fixed so that asymbol and reloc records are output
1443 * bfd.c lots of lint, support for new bfd entry point
1446 * bfd.h changed definition of asymbol to contain pointer to
1447 owning bfd, removed target dependencies.
1449 * cache.c took out print statements, put in BFD_ASSERT calls.
1451 * coff-code.h various lints, corrected linenumber output
1452 functionality. Added support for new style asymbols and
1453 bfd_print_symbol. Fixed so that asymbol and
1454 reloc records are handled correctly. Added timestamp.
1456 * icoff.c Added support for new howto shape.
1458 * liba.out.h Added support for new asymbol shape
1460 * libbfd.c various lints
1462 * libbfd.h various lints
1464 * libcoff.h added support for new asymbol shape.
1466 * sunos.c various lints. Added support for new asymbol shape
1467 and bfd_print_symbol.
1469 Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
1471 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
1472 pointer lint. Added support for callj relocation. Fixed bug where
1473 the last 32 bytes of the text section were overwritten by data. Fixed bug
1474 where archives of b.out didn't work due bfd_slurp_extended_name_table
1477 * sunos.c added support for n_other field. Braced the howto table so
1478 that it won't be affected by any lengthing of the howto struct typedef.
1481 * bfd.h added support for n_other field, added special_function
1482 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
1485 * bfd.c upgraded bfd_perform_relocation, various lints.

1489 * ChangeLog: Started ChangeLog for BFD.
1490 * ToDo: Create file for suggestions.
1492 * Makefile: Support easy loading into Saber C.
1493 Add dependencies for icoff.o and bcs88kcoff.o.
1494 Rename coff.c to coff-code.h. Change callers.
1496 * bfd.c (bfd_check_format): Allow the check_format routines
1497 to return the desired target vector, rather than just a Boolean.
1498 bfd.h (bfd_check_format): Change function pointer return type.
1499 archive.c (bfd_generic_archive_p): change callee.
1500 b.out.c (b_out_little_object_p, b_out_big_object_p,
1501 b_out_real_object_p): change callee.
1502 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
1503 in check_format transfer vectors that need a filler.
1504 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
1505 bcs88kcoff.c: change callee.
1506 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
1507 icoff.c: change callee.
1508 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
1510 * libbfd.c (zalloc): It should actually zero the storage!
1511 This was commented out for some reason.
1513 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
1514 This is so callers can avoid <stdlib.h> which doesn't exist
1517 * bfd.c (map_over_sections): Add debugging code, since I
1518 noticed the section count for sunos core files was bad, but only
1519 GDB had detected the problem.
1520 (bfd_set_section_lineno_size, bfd_set_section_linenos,
1521 bfd_get_section_linenos): Remove obsolete functions.
1522 (bfd_apply_relocations): Use longs, not ints, for the math.
1524 * bfd.h: Declare enum boolean and struct bfd_target as well
1525 as typedefs for them. Remove obsolete
1526 bfd_get_section_lineno_size.
1528 * cache.c: Make the "fdopen" support work. Keep better track
1529 of how many files are open. Centralize the opening of files
1530 and be sure bfd_open[rw] actually try to open the file. Evade
1531 linked list initialization problems.
1533 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
1535 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
1537 * cplus-dem.c: Delete file, since it is not part of BFD.
1539 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
1540 (bfd_openr, bfd_openw): Actually open the file, give error now.
1542 * sunos.c (sunos4_core_file_p): Set section count.
1543 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
1544 obsolete definitions.
1545 (_write_symbol_table): Initialize <idx> counter.
1546 (foop): Eliminate debugging code.
