17 Sat Dec 7 16:39:23 1991 Steve Chamberlain (sac at rtl.cygnus.com)
19 * Makefile.in: fix where docdir lives
21 * aoutx.h, archive.c, archures.c, bfd.c, cache.c, coff-m88k.c,
22 coffcode.h, core.c, ctor.c, elf.c, format.c, ieee.c, init.c,
23 libbfd.c, libbfd.h, libcoff.h, opncls.c, reloc.c, section.c,
24 srec.c, syms.c, targets.c : all new documentation and lint
28 Sat Dec 7 07:22:09 1991 John Gilmore (gnu at cygnus.com)
30 * coffcode.h, srec.c: Lint.
32 Fri Dec 6 22:58:48 1991 K. Richard Pixley (rich at rtl.cygnus.com)
34 * Makefile.in: install using INSTALL_DATA, added standards.text
37 * configure.in: mark directory as target dependent. configure
38 nows works in objdir always so make file existence checks
41 Thu Dec 5 22:46:19 1991 K. Richard Pixley (rich at rtl.cygnus.com)
43 * Makefile.in: idestdir and ddestdir go away. Added copyrights
44 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
45 and mandir now keyed off datadir by default.
47 Wed Dec 4 10:14:17 1991 Steve Chamberlain (sac at rtl.cygnus.com)
49 * aoutf1.h (sunos_<size>_object_p, sunos4_callback): moved the
50 computation of arch and machine type so it's worked out before
51 some_aout_object_p is called.
52 * aoutx.h: (some_aout_object_p): don't set arch and mach to
54 * archures.c: add extra field 'section_align_power' to hold
55 default section alignment in object files.
56 * cpu-a29k.c, cpu-h8300.c, cpu-i386.c, cpu-i960.c, cpu-m68k.c,
57 cpu-m88k.c, cpu-mips.c, cpu-rs6000.c, cpu-sparc.c, cpu-vax.c:
58 initialize the new field.
59 * bout.c (b_out_callback): replace the text size, since aout
61 * aoutx.h: Documentation in the new style
63 Wed Dec 4 02:00:30 1991 John Gilmore (gnu at cygnus.com)
65 * bfd.c (bfd_get_mtime): Don't cache mtime any more; only
66 use the saved value if mtime_set is already set (intended
67 for archive files, though apparently not used yet).
69 Tue Dec 3 22:54:50 1991 John Gilmore (gnu at cygnus.com)
71 * targets.c: Revise comments about how to configure the target
72 vector, to match reality. Remove mention of obsolete methods.
73 Remove long lists of capitalized macros that turn into the same
74 thing in lowercase. Normal vector simply lists all known
75 lowercase xvec names; all other cases are handled by SELECT_VECS.
77 * config/mt-i386-coff: Set DEFAULT_VECTOR to real identifier,
80 * config/mt-i960-{coff,bout}: Use SELECT_VECS to make a short
81 list of supported targets.
83 Tue Dec 3 14:06:15 1991 Per Bothner (bothner at cygnus.com)
85 * archive.c (bsd_write_armap): The pad byte sometimes added to
86 the string table in a __.SYMDEF member is now
87 counted as part of the size of the string table.
88 This is compatible with the old ranlib, as well as Sun's.
90 Tue Dec 3 10:53:30 1991 Steve Chamberlain (sac at rtl.cygnus.com)
92 * srec.c: Rewrote to fix many bugs; now gets the record type
93 right, doesn't choke on input, sets the start address in an S9 and
94 fills in the filename on an S0.
96 Sat Nov 30 21:19:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
98 * cpu-h8300.c: Add support for MEMIND addressing mode
100 * coff-a29k.c: defined RELOC_PROCESSING to take the #ifdef out of
102 * coffcode.h: use the new macro if available
104 * elf.c (elf_corefile_note): cast malloc to avoid warning.
105 * Makefile.in: Fixed dependencies due to file rename
107 * aout-encap.c, aoutf1.h, aoutx.h, archive.c, bout.c, coff-a29k.c,
108 coff-h8300.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
109 coff-mips.c, coff-rs6000.c, cpu-h300.c, elf.c, i386aout.c,
110 newos3.c, stab-syms.c, syms.c: All these files have had their
111 #includes altered to point to the new places.
113 Fri Nov 29 20:04:49 1991 Fred Fish (fnf at cygnus.com)
115 * config/mh-i386v4, config/mh-i386-elf, hosts/h-i386v4.h: New files.
117 * configure.in: Add vendor "ncr" as supported per-target vendor.
118 Add svr4 case for i386 per-host case.

123 Fri Nov 29 12:16:51 1991 Per Bothner (bothner at cygnus.com)
125 * syms.c (bfd_decode_symclass): Return 'A'
126 for symbols that are both absolute and global.
127 * archive.c (bfd_special_undocumented_glue): Return NULL
128 if bfd_ar_hdr_from_filesystem returns NULL.
130 Tue Nov 26 09:10:55 1991 Steve Chamberlain (sac at cygnus.com)
132 * Makefile.in: added coff-h8300
133 * configure.in: now h8 is a coff target
134 * cpu-h8300.c: fix various disassembly problems
135 * libcoff.h: took out some code which has been #0ed for a long
137 * targets.c: added h8 coff
138 * coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c
139 added new macro RTYPE2HOWTO to take a load of #ifdefs out of
141 * coffcode.h: Started to change the way machine dependencies are
142 handled, from the nest of #ifdefs to macros defined in the
143 including coff-<foo>.c
145 Fri Nov 22 08:11:42 1991 John Gilmore (gnu at cygnus.com)
147 * aoutx.h (some_aout_object_p): Set the `executable' bit
148 if the entry point is contained in the text segment, even if the
149 text segment is at location 0.
151 * coff-mips.c, coffcode.h: Peter Schauer's patch to kludge in
152 nonstandard MIPS sections (.rdata, .sdata, etc).
154 * aoutx.h, bfd.c, coffcode.h, ieee.c, oasys.c, targets.c: CONST lint.
155 * libbfd-in.h, libbfd.h, aoutx.h, coffcode.h, elf.c, libaout.h:
156 Rename ALIGN to BFD_ALIGN to avoid conflict with BSD <sys/param.h>.
158 * host-aout.c, trad-core.c: Fix write_armap prototypes. Lint.
160 Thu Nov 21 19:56:40 1991 Per Bothner (bothner at cygnus.com)
162 * stab-syms.c, syms.c: Moved bfd_stab_name() and bfd_stab_names[]
163 from syms.c to new file stab-syms.c. Also, since GNU extended
164 type codes such as N_SETT are no longer in ../include/stab.def,
165 include them manually.
166 * stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
167 bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
168 * libaout.h: Added prototype for aout_stab_name().
169 * Makefile.in: Update Makefile for new stab-syms.[co].
171 Thu Nov 21 11:50:49 1991 John Gilmore (gnu at cygnus.com)
173 * libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this
174 rather complicated seeming problem. Eliminate LOGICAL_ versions,
175 just make N_XXX work by excluding the header from the text segment.
176 * aoutx.h: Fix comments to match.
178 Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
180 * libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
181 LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
182 for the "logical" text segment (i.e. never consider the exec
183 header to be part of the text segment). This change is
184 needed for consistency with various other parts of bfd and ld.
185 * aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
186 and move calculation of obj_textsec(abfd)->size to libaout.h.
187 * bfd-in.h: Removed bogus ';'.
189 * Makefile.in: Add MINIMIZE flag to select lean
190 or bloated target_vector.
191 * targets.c: Use new MINIMIZE macro, and add trad_core if needed.
192 * newsos3.c: Fixes to ../include/aout64.h remove need
193 for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
195 Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
197 * aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h
198 handle both little and big-endian targets, with little
199 the default unless TARGET_IS_BIG_ENDIAN_P is defined.
200 * host-aout.c: Add FIXME note.
202 Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
204 * targets.c: Make the default target_vector contain
205 just &DEFAULT_VECTOR. This makes executables a lot smaller.
206 Old behavior can be gotten by defining ALL_TARGETS.
207 * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
208 Factored out common code into new file aout-target.h.
209 Saves a lot of duplicate code for a.out variants.
211 Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)
213 Get 'make headers' to work when configured with +subdirs.
214 * Makefile.in: Add $(subdir) to docdir path.
215 * doc/Makefile.in (protos): Add $(srcdir) prefix
216 to name of sed scripts.
218 Thu Nov 14 19:49:10 1991 Per Bothner (bothner at cygnus.com)
220 * aoutx.h (NAME(aout,print_symbol)): Fix thinko.
221 * syms.c (bfd_stab_names): Turn on new GNU_EXTRA_STABS macro
222 to include names of N_SETT etc.
224 Thu Nov 14 19:11:13 1991 Fred Fish (fnf at cygnus.com)
226 * elf.c: Add minimal support for ELF symbol tables. Generates
227 canonical bfd symbol tables from ELF symbol tables. Change the
228 name of some functions from bfd_<name> to elf_<name>.
230 * syms.c: Trivial fix to comment to remove a redundant "to".
232 Wed Nov 13 17:02:01 1991 John Gilmore (gnu at cygnus.com)
234 * coff-{i386,m68k,m88k}.c: Change name of file format to standard
235 form that GDB recognizes as COFF.
237 Wed Nov 13 09:09:41 1991 Steve Chamberlain (sac at cygnus.com)
239 * ieee.c (ieee_object_p): cast NULL correctly.
240 * configure.in: added harris host

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

257 * elf.c: Additions to support ELF format core files.
258 * config/mh-amix: Add -DHAVE_PROCFS to HDEFINES, since host
259 has support for /proc (all the include files in particular).
261 Mon Nov 11 18:36:47 1991 Per Bothner (bothner at cygnus.com)
263 * aoutx.h (NAME(aout,find_nearest_line)): Handle the case
264 of two N_SO stabs, one for directory, and one for filename.
266 * bfd-in.h (print_vma): Factor out duplicate definition.
268 Exit a little more gracefully when malloc returns NULL.
269 * libbfd.c: New function bfd_xmalloc (malloc wrapper).
270 * opncls.c, syms.c, bout.c, aoutx.h: Replace malloc by bfd_xmalloc.
271 * libbfd.h: Rre-generated due to libbfd.c update.
273 Sat Nov 9 13:45:01 1991 Fred Fish (fnf at cygnus.com)
275 * config/mt-m68k-elf: Define DEFAULT_VECTOR as elf_big_vec.
277 * elf.c (elf_object_p): Don't try to create a bfd section for
278 the first ELF section header. It is just a placeholder.

282 * coff-rs6000.c, config/mh-rs6000: Make it work on archive and
283 core files, when compiling native.
284 * hosts/h-rs6000.h: Define FASCIST_FDOPEN for bfd_fdopenr.
286 FIXME: The aoutf1.h change below needs to be reversed back
289 Thu Nov 7 11:03:55 1991 Steve Chamberlain (sac at rtl.cygnus.com)
291 * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
292 manipulation of lnno fields in lineno structs in a coff-<f>.h
293 independent way. Override it in coff-<f>.h to your favourite
294 number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
295 (coff_swap_lineno_out): modified to use the new macros.
297 Mon Nov 4 11:38:33 1991 Steve Chamberlain (sac at cygnus.com)
299 * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
300 unknown arch when the magic number doesn't specify the
301 architecture, since some OSs (eg old sun3s) don't set the number, and
302 020 is probably the right answer anyway.
304 Sun Nov 3 12:07:08 1991 Per Bothner (bothner at cygnus.com)
306 * hosts/h-news.h, hosts/h-rtbsd.h:
307 Get rid of MISSING_VFPRINTF, since libiberty provides one.
308 * bfd-in.h (bfd_print_symbol_type_hopw enum): Add new option
309 bfd_print_symbol_nm, for use by nm.
310 * aoutx.h (NAME(aout,print_symbol)): Add code for new
311 bfd_print_symbol_nm option, to print in nm format.
312 * coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
313 oasys.c (oasys_print_symbol): Provide stub implementations
314 for bfd_print_symbol_nm.
315 * syms.c: New function bfd_decode_symclass, used by nm printer.
316 New function bfd_stab_name to look up string name of stab code.
318 Sat Nov 2 14:26:03 1991 Steve Chamberlain (steve at cygnus.com)
320 * Makefile.in: Added ctor.c
321 * archures.c (bfd_default_arch_struct) added
322 bfd_default_reloc_type_lookup.
323 * coffcode.h: removed a load of #if 0ed code.
324 (coff_compute_file_section_positions): now works out the section
325 alignment and size correctly in all cases.
326 (coff_get_symtab): looks for constructor symbols and calls the
327 right function when they're found. (coff_canonicalize_reloc):
328 knows when a section is full of constructors and does the right
330 * cpu-m88k.c: Added default_reloc_type lookup to the architecture
332 * libbfd-in.h: (bfd_default_reloc_type_lookup) defun added.
333 * libcoff.h: removed #if 0ed code
334 * reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
335 arch independent constructor relocation type.
336 (bfd_reloc_type_lookup): removed the comment "this will go away"
337 since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
338 reloc which is used when BFD_RELOC_CTOR falls through to give a
339 default 32bit reloc for constructors.
340 (bfd_default_reloc_type_lookup): added.
341 * aoutf1.h: fixed SEGMENT_SIZE typo.
343 Thu Oct 31 18:23:06 1991 John Gilmore (gnu at cygnus.com)
345 * coff-rs6000.c: Change name to "aixcoff-rs6000", to avoid
346 matching prefix "coff".
347 * coffcode.h (coff_swap_aux_in, coff_swap_aux_out): Handle
348 rs/6000 csect records.
350 Sun Oct 27 16:56:58 1991 Steve Chamberlain (steve at cygnus.com)
352 * coff-m88k.c, targets.c: change name of m88k_bcs to m88kbcs

394 existing section before making one.
395 * cpu-rs6000.c: New file.
396 * rs6000coff.c: New file.
398 Thu Oct 24 02:03:24 1991 Fred Fish (fnf at cygnus.com)
400 * elf.c: Add partial support for ELF format corefiles. Still needs
401 support for extracting registers from corefiles.
403 * config/t-m68k-elf: Set DEFAULT_VECTOR to elf_big_vec.
405 * config/{h-amix,h-dgux,h-irix3,h-ultra3}: For systems where
406 RANLIB is defined as echo, send the output to /dev/null to help
407 reduce clutter in the output from doing a make.
409 Mon Oct 21 17:48:48 1991 John Gilmore (gnu at cygnus.com)
411 * hosts/h-vaxult.h: Remove malloc/free decls covered in stdlib.h.
412 Fix HOST_PAGE_SIZE and HOST_SEGMENT_SIZE. From David Taylor.
414 Mon Oct 21 09:34:11 1991 Steve Chamberlain (steve at rtl.cygnus.com)
416 * coffcode.h (coff_compute_section_file_positions): make it pad
417 section size out if there are alignment restrictions so that the
418 image will be ok on a system where section positions are worked
419 out by accumulating sizes rather than from the section headers.
420 * targets.c (proto write_armap). Changed orl_count to unsigned.
421 * opncls.c (bfd_close_all_done). Added so that generative
422 programs like gas can close a bfd without causing bfd confusion.
423 * libbfd.h (changed becuase of protos)
424 * amdcoff.c: messed with the way that jmp displacements are
425 calcualated. This may not yet be totally correct.
426 * archive.c (coff_write_armap): rewrote the way that ranlibs are
428 * coffcode.h (fixup_symbol_value): now doesn't core dump if a non
429 abs symbol has no section (like a register symbol).
430 (coff_write_symbol) now zeros auxent before filling it up to help
431 with sensitive applications.
432 * libbfd.c (bfd_write_bigendian_4byte_int): added.
434 Wed Oct 16 22:58:45 1991 John Gilmore (gnu at cygnus.com)

437 * opncls.c (bfd_fdopenr): If FASCIST_FDOPEN, use "r", not "r+".
438 * trad-core.c (trad_unix_core_file_failing_command): Suppress
439 attempt to recover command, ifdef NO_CORE_COMMAND.
440 * hosts/h-tahoe.h: Add FASCIST_FDOPEN and NO_CORE_COMMAND;
442 * hosts/h-i386v.h: Use <utime.h>, not <sys/utime.h>, unlike POSIX.
444 Wed Oct 16 12:43:49 1991 Per Bothner (bothner at cygnus.com)
446 * archive.c (bsd_write_argmap): The size of the ranlib structures
447 should not include the size field itself.
448 * aoutx.h, libaout.h (NAME(aout, sizeof_headers)): Use
449 adata(abfd)->exec_bytes_size field instead of constant macro,
450 because aoutx.h compiles to a simple .o file shared by
451 all 32-bits a.out targets.
453 Wed Oct 16 11:11:05 1991 John Gilmore (gnu at cygnus.com)
455 * configure.in: Allow i386-sco-sysv.
456 * bout.c: Remove unused i960_align; lint dummy core file handlers.
459 * host-aout.c: New strategy. We use common code, include files,
460 and data structures to handle the file, but set a few parameters
461 from the host's config file (page size, text start addr, etc).
462 * libaout.h: Define HP BSD machine types.
463 * aoutf1.h: Handle reading a.outs with these types.
465 * trad-core.c: Pass the u.u_ar0 value as the negative of the
466 virtual-memory-address of the .reg section. We can't just make a
467 section for "all the regs and nothing else" because only GDB knows
468 exactly where the regs are (scattered around the upage and stack).
469 Clean up memory allocation. Remove big- and little-endian
470 vectors, replace with single vector; this only runs on the host,
471 in host byte order. Replace byteswap routines with aborts in case
473 * targets.c: There's only one trad_core_vec now.
474 * aoutf1.h (sunos_core_file_p): VMA of .reg* now needs to be 0.
476 Tue Oct 15 08:29:03 1991 John Gilmore (gnu at cygnus.com)
478 * hosts/h-amix.h (free): Fix prototype.
480 * aoutx.h: Don't use NULL as an integer, for braindead systems
481 that declare it as (void *)0. (From Peter Schauer.)
483 Mon Oct 14 17:20:47 1991 Per Bothner (bothner at cygnus.com)
485 * opncls.c (bfd_fdopenr): Add parentheses to avoid reported
486 problem with bad Ultrix system headers.
487 * aoutx.h (NAME(aout,set_section_contents)): Try to handle the
488 various kinds of alignments for the various kinds of
491 Mon Oct 14 14:23:10 1991 John Gilmore (gnu at cygnus.com)
493 * doc/Makefile: Don't assume . is on the path (from James Clark).
495 Fri Oct 11 22:45:14 1991 John Gilmore (gnu at cygnus.com)
497 * Makefile.in: Avoid Sun Make VPATH bugs.
498 * targets.c: Declare trad_core vectors extern.
500 Fri Oct 11 13:03:02 1991 Per Bothner (bothner at cygnus.com)
502 * coffcode.h: Moved ALIGN macro to libbfd.h. Removed i960_align.
503 * libbfd.h: Moved ALIGN macro here.
504 * bout.c (b_out_callback): Replace i960_align by align_power.
506 * libaout.h (struct aoutdata): Added fields page_size,
507 segment_size and exec_bytes_size. These help generic code
508 (in aoutx.h and libaout.h) to figure out where to align
509 the various segments in a demand paged file.
510 * libaout.h (WRITE_HEADER): Use new (struct aoutdata) fields
511 to decide if the exec header counts in a_text (text segment size).
512 Also, assume D_PAGED flag is set; don't set it here.
513 * bout.c (b_out_callback): Add initialization of
514 adata fields page_size, segment_size, and exec_bytes_size.
515 * host-aout.c (NAME(host_aout, callback) and
516 NAME(host_aout,mkobject): Ditto.
517 * i386aout.c (aout386_callback) and new aout386_mkobject): Ditto.
518 * newos3.c (newsos3_callback) and new newsos_mkobject): Ditto.
519 * aoutf1.c (sunos4_callback) and new sunos_mkobject): Ditto.
520 * aoutx.h (NAME(aout,some_aout_object_p)): Don't subtract
521 EXEC_BYTES_SIZE from the a_test size; this is only appropriate
522 for some systems (mainly sunos), so do it in the callback instead.
523 Same routine: Add stuff to the THIS_IS_ONLY_DOCUMENTATION comment.
524 * aoutx.h (NAME(aout,set_section_contents): Change the way
525 filepos and size of sections are carried out to support
526 older styles of demand paged executables.
529 Fri Oct 11 12:33:36 1991 Steve Chamberlain (steve at cygnus.com)
531 * bfd-in.h: Added more macros to COFF_SWAP_TABLE.
532 * bfd.c: Added macros to enable gas to swap coff records.
533 * coffcode.h: Make the coff_swap_*_out routines return the number
534 of bytes swapped, and cleaned up their prototypes.
535 * configure.in: Added ebmon/coff support
536 * ecoff.c: Changed null definitions of coff_swap_*_out to conform
538 * targets.c: Added new entry points for coff swapping
540 Fri Oct 11 03:01:52 1991 John Gilmore (gnu at cygnus.com)
542 Restructure configuration scheme for bfd, binutils, ld.
544 * include/sys/h-*.h: Move to bfd/hosts/h-*.h.
545 * configure.in: Revise to symlink sysdep.h to hosts/h-xxx.h.
546 Change some config names to match other dirs.
547 * *.c: Include bfd.h before sysdep.h, so ansidecl and PROTO()
549 * Makefile.in: Use -I. to get sysdep.h. Remove refs to
551 * cpu-i960.c: Strncmp needed a length arg.
552 * ecoff.c: Don't ever call trad_unix_core_file_p from here.
553 * i386aout.c: Remove dead N_TXTOFF override.
554 * trad-core.c: Don't disable the whole file if SUN4_SYS.
555 * config/: Rename some config files to match up h-*.h names.
556 Remove all the HOST_SYS definitions from the config files.
557 * hosts/h-amix.h, h-i386v.h: Define POSIX_UTIME, not USG.
558 * hosts/h-hp9000.h: Remove USG comment.
559 * hosts/h-rs6000.h: Include <stdlib.h> for malloc.
560 * hosts/h-news.h, h-sparc-64.h: New config files that had
561 previously been kludged in the <sysdep.h> file.
563 Thu Oct 10 17:54:08 1991 John Gilmore (gnu at cygnus.com)
565 * config/*: trad-core support is HOST dependent, not target
566 dependent. Target config files only set DEFAULT_VECTOR and/or
567 other vector elements. Exception: when host-aout.c is in use,
568 in which case we're forced to assume we're native (hp, vax,
569 tahoe). Rename XDEPFILES to HDEPFILES.
570 * Makefile.in: Rename XDEPFILES.
571 * config/h-sun*: Don't force static linking.
572 * trad-core.c: Document how to use it nowadays.
573 * i386aout.c, newsos3.c: Clean up.
574 * i386coff.c: Allow 386 coff files to be used as core files too
575 (for reading core files from embedded systems).
577 Tue Oct 8 15:30:39 1991 John Gilmore (gnu at cygnus.com)
579 * Add i386aout.c for a.out support on the i386.
581 Tue Oct 8 12:18:54 1991 Roland H. Pesch (pesch at cygnus.com)
583 * reloc.c, section.c, syms.c, targets.c: correct info-node
584 structure in *doc* comments.
585 doc/Makefile: stop hiding complaints from makeinfo.
587 Sun Oct 6 19:10:06 1991 John Gilmore (gnu at cygnus.com)
589 * aoutx.h (...some_aout_object_p): Take a third parameter,
590 the internal_exec struct, and avoid ever looking at an
591 external_exec. All callers changed to read the entire
592 external_exec struct, swap and check its magic number,
593 swap in the whole structure, and pass the swapped-in version to
595 * bout.c: Bring into modern era. Use single _object_p routine
596 for big- aand little-endian. Provide internal and external
597 exec header structs. Use separate swap-in and swap-out routines.
599 * libaout.h: Move struct internal_exec from ../include/aout64.h
600 to here. Add obj_symbol_entry_size to struct aoutdata.
601 * aoutx.h (...some_aout_object_p): Set obj_symbol_entry_size.
603 * ../include/aout64.h: Change EXTERNAL_LIST_SIZE to
604 EXTERNAL_NLIST_SIZE. Callers changed.
606 Fri Oct 4 18:18:46 1991 John Gilmore (gnu at cygnus.com)
608 * bfd.c: Remove strerror() to libiberty.
610 * elf.c: Remove elf_set_section_contents, use generic one. Lint.
611 * libbfd-in.h, libbfd.c: Add bfd_generic_set_section_contents.
612 * libbfd.c (bfd_generic_{get,set}_section_contents): Check that
613 last byte of transfer, not first byte, is within the section.
615 * host-aout.c: Remove `BSD' archive support. Lint.
617 * archures.c: Rename `struct bfd_arch_info_struct' to `struct
618 bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
619 `bfd_arch_info_type'. All uses changed.
620 * reloc.c: Rename `bfd_reloc_status_enum_type' to
621 `bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
622 to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
623 it needs a better name.) All uses changed.
624 * targets.c: Rename `enum target_flavour_enum' to `enum
625 target_flavour', and remove the `_enum' from all of the enum
626 values themselves. All uses changed.
628 * configure.in, config/h-i386mach: i386 mach host.
629 * config/t-i386-aout: Use host-aout.c.
631 * trad-core.c: Give it its own xvec's to make it independent
632 of other file formats.
633 * ecoff.c, host-aout.c: Remove refs to trad-core.
634 * config/t-dec3100, t-hp300bsd, t-tahoe, t-vax: Define TRAD_CORE.
635 * targets.c: #ifdef TRAD_CORE, include it in the vector.
637 Fri Oct 4 17:38:03 1991 Steve Chamberlain (steve at cygnus.com)
639 * reloc.c: Extended NEWHOWTO macro
640 * ieee.c: Changed the way 8bit pcrel is done
641 * cpu-h8300.c: got the registers in the right order
643 Thu Oct 3 19:39:55 1991 John Gilmore (gnu at cygnus.com)
645 * bfd-in.h: enum boolean => enum bfd_boolean for SVR4. Gumby's
646 prediction is vindicated!
648 * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
649 Remove refs to howto.c, since Steve forgot.
651 Thu Oct 3 07:49:21 1991 Steve Chamberlain (steve at cygnus.com)
653 * elf.c: took the abort out of set_arch_mach so that objdump -i will
654 still work. Now allows any architecture/machine to be set.
656 Wed Oct 2 13:50:35 1991 Steve Chamberlain (steve at cygnus.com)
658 * howto.c deleted and moved code to reloc.c
660 * libbfd.h, libbfd-in.h removed $id stuff for real
662 * cpu-h8300.c Made it match various different spellings of h8300.
664 * archures.c: Took out the first char filter which made it only
665 look for a cpu/arch match when the first chars of supplied and
666 tested names were the same.
668 * targets.c removed oasys stuff, pending someone to fix the bugs
672 Tue Oct 1 12:29:44 1991 John Gilmore (gnu at cygnus.com)
674 * Makefile.in, configure.in, targets.c, elf.c: Add preliminary
675 ELF support good enough for GDB.
676 * configure.in, config/h-amix, config/t-m68k-elf: Handle
677 m68k-cbm-svr4 host and target.
678 * config/t-m68k-coff, t-m88k-coff, t-m88k-aout: Make files nonempty
679 so `diff' and `patch' can cope.
681 Tue Oct 1 11:24:31 1991 Steve Chamberlain (steve at cygnus.com)
683 * archures.c: removed texinfo error
685 * init.c: added texinfo hooks, and removed initialization error
688 * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
691 Tue Oct 1 05:02:53 1991 John Gilmore (gnu at cygnus.com)
693 * cpu-i960.c: Avoid numerical count of initializers.
695 Vax Ultrix changes from David Taylor <taylor@think.com>:
696 * host-aout.c: Make little-endian vector really little-endian.
697 * configure.in: Separate vax and tahoe cases, handle ultrix.
698 * config/t-vax: Add trad-core.o.
699 * config/h-vaxult: New host system.
701 Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
703 * bfd-in.h VERSION, change version number to 0.18, this makes a
704 gap, but now is the same as the linker version number.
706 * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
707 cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
708 files will eventually contain processor specific bits for bfd,
709 like strange relocation information and dis/assembly. So far only
710 the H8 has been even partially done. This work also ties in with
711 the change in handling architectures.
713 * amdcoff.c: (a29k_reloc) fix error message.
715 * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
716 discover the architecture of the bfd. (sunos4_callback) calls the
717 function bfd_set_arch_mach rather than stuffing stuff directly
718 into the bfd. (sunos4_write_object_contents), changed names of
721 * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
722 setup the environment.
724 * archive.c: (bfd_slurp_coff_armap) coff archives always have the
725 headers in big endian format, regardless of the endianess of the
728 * archures.c: totally changed. Now an architecture is represented
729 with a pointer to an info structure rather than an enumerated type
730 and a long. The old info is available as two elements in the
731 structure. Future enhancements to architecure support will
732 involve pointers to methods being placed into the info structure.
734 * bfd.c: changed the definition of the bfd structure for the new
737 * bout.c: (b_out_set_arch_mach) changed to use the new
738 architecture mechanism.
740 * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
741 the new architecture mechanism.
743 * configure.in: added h8 stuff.
745 * ieee.c: too many changes to note. Now ieee files written with
746 bfd gas and ld can be read by gld and ieee only linkers and
749 * libbfd.c, libbfd.h: changed prototype of bfd_write.
751 * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
752 than fixing the structure directly.
754 * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
755 than fixing the structure directly.
757 * opncls.c: (new_bfd) makes sure that bfd_init has been called
758 before opening a bfd.
760 * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
761 rather than fixing the structure directly.
763 * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
764 in the t/hmake file) a user can select which backends they want
765 linked with bfd without changing the source.
767 * init.c: new, looks after initializing modules.
769 * howto.c: for future use, will allow an application to work out
770 what cookie to use as a handle on a relcoatio howto.
772 Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
774 * srec.c: Better error checking, partly from Peter Schauer.
775 (srec_object_p): Avoid assuming any file that starts with 'S' is
776 an S-record file! (Check for 3 uppercase-hex digits after it.)
777 (ISHEX): Define new macro for checking supposedly hex characters.
778 (pass_over): Treat as EOF any S-record line that:
779 * doesn't have hex in either size character
780 * produces a size larger than 0x7F
781 * has an unrecognized type number
783 Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
785 * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
786 opncls.c: Lint (saber actually).
788 Thu Sep 26 11:24:24 1991 Per Bothner (bothner at cygnus.com)
790 * libaout.h (WRITE_HEADERS): Set header's a_text field always.
791 * newsos3.c: Fixed two types: newos3 -> newsos3.
792 * reloc.c (bfd_perform_relocation): Fix pc-relative relocation
793 to use correct segment.
795 Mon Sep 23 18:24:34 1991 Per Bothner (bothner at cygnus.com)
797 * aoutx.h (print_symbol): Handle missing symbol->name.
799 Fri Sep 20 12:26:01 1991 Stu Grossman (grossman at cygnus.com)
801 * aoutf1.h (swapcore_sparc): Change name of USRSTACK, fix comment
804 Tue Sep 17 17:23:49 1991 Stu Grossman (grossman at cygnus.com)
806 * oasys.c, configure.in, config/h-irix3, config/t-irix3:
807 add sgi/irix support.
809 Thu Sep 12 14:29:09 1991 John Gilmore (gnu at cygint.cygnus.com)
811 Changes for the AMD 29000 Ultracomputer port from David Wood.
814 * opncls.c (bfd_fdopenr): Handle NO_FCNTL.
816 * Makefile.in: Make subdirs work by using $(INCDIR) in the
819 * coffcode.h (coff_real_object_p): Pass information about the
820 current file's coff symbol format to BFD via the coff_data struct.
821 (coff_find_nearest_line): obj_icof => coff_data.
822 (coff_swap_sym_{in,out}): Check that SYMNMLEN == E_SYMNMLEN.
823 (coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
824 and DIMNUM == E_DIMNUM.
825 * configure.in: Handle a29k-*-* hosts, and targets
826 a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
827 * libcoff-in.h: Add local_n_btmask, local_n_btshft,
828 local_n_tmask, local_n_tshift, local_symesz, local_auxesz,
829 local_linesz to `coff_data' (tdata) struct.
830 (coff_data, coff_data_type, coff_tdata): Rename struct icofdata.
831 * config/h-ultra3: Handle a29k-*-* hosts as Ultracomputers.
833 Thu Sep 12 14:07:22 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
835 * Makefile.in: $(MAKE) for make, $(docdir) for doc
836 * doc/Makefile: redundant dependencies for Sun-make VPATH bug
838 Tue Sep 10 20:34:12 1991 John Gilmore (gnu at cygint.cygnus.com)
840 * aoutf1.h (sunos4_core_file_p): Release the right storage in
842 (sunos4_core_file_matches_executable_p): Fix header comparison.

844 * bout.c, icoff.c, ieee.c, libbfd.c, oasys.c: gcc -O -W lint.
846 Wed Sep 4 00:44:52 1991 John Gilmore (gnu at cygint.cygnus.com)
848 Allow GDB to patch object files.
850 * aoutf1.h (sunos_core_file_p): Set SEC_HAS_CONTENTS on all sections.
851 * trad-core.h (trad_unix_core_file_p): Ditto.
852 * aoutx.h (aout_set_section_contents): On first output, check
853 abfd->direction and complain if erroneous.
855 * Makefile.in: Add crude dependencies.
857 Tue Sep 3 13:46:19 1991 Steve Chamberlain (steve at cygint.cygnus.com)
859 * config/* aoutx.h configure* shortened all the h/tmake-xxxx
860 to h/t-xxxx files so that everything will work on System V.
862 Fri Aug 23 13:51:06 1991 John Gilmore (gnu at cygint.cygnus.com)
864 * aoutx.h: Add information on host-aout.c and how to configure
865 to use it, to the manual.
866 * configure.in: Tix typo.
867 * ecoff.c: If compiling for DEC3100, use trad_unix core files,
868 else dummy out the core file support.
869 * trad-core.c (trad_unix_core_file_p): If HOST_DATA_START_ADDR is
870 specified, use it to locate the data section.
871 * coffcode.h (coff_write_symbols): Declare buffer as bfd_bytes
872 rather than as chars (lint).
874 Thu Aug 22 22:20:19 1991 Stu Grossman (grossman at cygint.cygnus.com)
876 * aoutx.h, coffcode.h: saberized.
878 Thu Aug 22 11:27:06 1991 Roland H. Pesch (pesch at cygint.cygnus.com)

885 Wed Aug 21 19:13:22 1991 John Gilmore (gnu at cygint.cygnus.com)
887 * trad-core.c (trad_unix_core_file_p): Use HOST_TEXT_START_ADDR,
888 etc, rather than TEXT_START_ADDR.
889 * host-aout.c: Remove #if 0 around whole thing.
890 Update to modern (32/64-bit) a.out naming conventions.
891 Include a large chunk of ../include/a.out.gnu.h to get macros that
892 are not defined by the system include files.
893 (host_aout_{32,64}_write_object_contents): Use the WRITE_HEADERS
894 macro used by the other a.out implementations.
895 * Makefile.in: Give dependencies to OPTIONAL_BACKENDS.
897 Wed Aug 21 14:33:06 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
899 * Makefile.in: use targets "bfd.dvi" and "bfd.ps" instead of
900 texdoc and psdoc; make these depend on generated .texi's
902 * scanit, (new) unPROTO: turn PROTO macros into ANSI declarations in
905 * bfd.c, reloc.c, syms.c: minor spelling/wording fixes in doc
908 * Makefile.in, awkscan-ip, awkscan-p, intobfd,
909 libbfd.h, libcoff.h, tolibcoff; new bfd-in.h, libbfd-in.h,
910 libcoff-in.h: (a) use separate files for invariant parts of bfd.h,

951 * all files: update copyright notices for GPL version 2.
952 Install header comments and attribute most modules to their
953 authors. BFD's name is now officially "Binary File Descriptor",
954 so remove any conflicting pejoratives.
955 archures.h: Consists solely of comments; remove it.
957 Fri Jul 26 18:11:34 1991 Steve Chamberlain (steve at cygint.cygnus.com)
959 * Makefile.in, bfd.c: Made it compile again.
961 Fri Jul 19 08:17:09 1991 Steve Chamberlain (steve at cygint.cygnus.com)
963 * newsos3.c, targets.c, coffcode.h: new patches from David Wood
966 Mon Jul 15 16:27:42 1991 Steve Chamberlain (steve at cygint.cygnus.com)
968 * aoutf1.h archive.c bfd.c coffcode.h core.c ecoff.c ieee.c
969 bfd.texinfo oasys.c opncls.c reloc.c srec.c: More documentation on
972 * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd
973 29k coff by David Wood (wood@lab.ultra.nyu.edu).
975 Thu Jul 4 09:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
977 * Everything: created some new files, core.c format.c, reloc.c,
978 section.c and syms.c to split the functionality a bit better.
979 Cleaned up the rest of the files a bit, and added some
983 Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu)
985 * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
986 really takes 3 arguments, patched code and ammended prototypes.
988 Fri Jun 14 13:19:40 1991 Steve Chamberlain (steve at cygint.cygnus.com)
990 * ../include/bfd.h (struct bfd_target): Added new field
991 "align_power_min" which contains the minimum alignment for a
992 section. This is used in coff_new_section_hook. The field
993 insertion necessitates an update of all backends..
995 * aoutf1.h jump table field inserted
997 * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended
1000 * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump
1001 table field inserted.
1003 * coffcode.h(just about everything) Now patches up symbol tables
1004 using a different mechanism. The Intel major bug has been fixed,
1005 and the linker can self host on the Aviion and be debugged with
1008 * ecoff.c: new include and jump table patch, i386coff.c: new
1009 include and jump table patch, icoff.c: new include and jump table
1010 patch, ieee.c: can now read archives containing ieee modules.,
1011 libcoff.h: added (combined_entry_type), libieee.h: uped max
1012 sections to 20, m68kcoff.c: new include and jump table patch,
1013 m88kbcs.c: new include and jump table patch, oasys.c: various bugs
1014 fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish.
1015 srec.c: jump table patch. trad-code.c fixed #IF typeo
1017 Fri Jun 7 12:35:46 1991 Sean Fagan (sef at cygint.cygnus.com)
1019 * coffcode.h (coff_swap_aux_in): added else case to deal with
1020 filenames less than 9 characters.
1023 Thu Jun 6 18:27:38 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1025 * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works
1027 * srec.c: now allows any number of sections to be created in a
1028 file. Outputs addresses of the right length.
1030 Thu May 30 15:30:10 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1032 * bfd.c (bfd_check_format): Fixed problem where when a defaulted
1033 target didn't match, the format got set to the attempted match,
1034 breaking a future test.
1036 *../include/i386coff.h : fixed typo in type field with size
1038 * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
1039 support in the jump table for the swapping routines exported to
1040 gdb. Now gdb works with the 386.
1042 Tue May 28 17:21:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1044 * Merge in changes from gdb-3.95 release.
1045 Makefile.in: Allow hmake and tmake files to add OFILES.
1047 bfd.c: support specific targets as well as searching. When
1048 searching, take default target in preference to others.
1050 ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment.
1051 liba.out.h: Don't hard-code file offsets; use N_ macros for them.
1052 libbfd.h: Support specific targets as well as searching.
1053 opncls.c: Support specific targets as well as searching.
1054 targets.c: Search is short-circuited if default target matches.
1055 liboasys.c, libieee.c: Undo bothner changes that make macros
1056 work to the left of assignment, but which depend on the
1057 representations of different pointer types being the same.
1059 Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1061 * i386coff.c: created.
1062 * coffcode.h: added support for 386.
1063 * Makefile.in: added support for 386.
1064 * ../include/i386coff.h: created
1066 Wed May 22 07:26:38 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1068 * coffcode.h: removed all put_x_<sizes>
1069 * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added
1073 Tue May 21 08:58:58 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1075 * opncls.c: Changed obstack_chunk_alloc use xmalloc
1077 Mon May 20 17:12:17 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1079 * everything: Removed sysdep.h from bfd.h and put back into files
1080 from which it was split out. Now 64 bit version is built with a
1081 -DHOST_64_BIT="long long" on the compile line.
1084 Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1086 Changed all the [get|put][name] routines to use [get|put]_[size
1089 Put in support for 64 bit work. Now two versions of bfd may be
1090 generated, according to the state of TARGET_64_BIT, one which is
1091 32 bit only, and one which is 64/32 bits.
1092 Created new back end 'demo64' to test 64 bit functionality.
1094 Renamed some files to work on DOS.
1096 * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
1097 64bit transfer * icoff.c: added 64bit transfer * ieee.c: name
1098 chage, 64 bit transfer. * liba.out.h: Split out common code from
1099 sunos and newsos into liba.out. Name changes and prototype mods. *
1100 libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
1101 prototypes for new functions. * libcoff.h: lint * libieee.h: make
1102 work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
1103 change and 64bit stuff.* newsos3.c: common code removed, new jump
1104 table. * oasys.c: Name change * opncls.c: Portability fixes *
1105 srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
1106 Added demo * aout32, aout64.c include aoutx.h * bout.c: used to
1107 be called b.out.c * coffcode.h: used to be called coff-code.h, now
1108 64bit ized. * demo64.c: 64 bit a.out back end
1114 Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1116 * libieee.h: Make ieee_data and ieee_ar_data macros usable
1117 on LHS of assignment, even when using old compilers.
1118 * liboasys.h: Ditto for oasys_data and oasys_ar_data.
1119 * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
1120 * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
1121 * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
1122 * targets.c: Add declaration of newsos3_vec.
1125 Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1127 * aout.c: fixxed some of the problems with filepos calculation.
1128 (swap_ext_reloc): fixed problem with creation of relocs.
1129 (aout_set_section_contents): fixed filepos problem
1131 * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
1132 (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
1133 (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
1134 (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
1135 cleaned up. (coff_write_object_contents) cleaned up.
1137 * ecoff.c: Totally different. Now supports ecoff fully.
1139 * icoff.c: fixed problems in relocation callout.
1141 * libcoff.h: (struct icofdata) removed hdr structure from tdata.
1143 * m68kcoff.c: updated target vector.
1145 * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
1146 choose_reloc_size. (sunos4_write_object_contents) now calls
1147 choose_reloc_size so outputs relocs correctly, also calculates the
1148 size of the sections correctly.
1152 Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1154 Merge Per Bothner's changes to modularize BFD a.out a bit.
1156 * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
1157 * ieee.c: Cast enums to int before comparing them, for brain-
1159 * coff-code.h: Remove coff_get_section_contents, and use the
1160 generic one instead.
1162 * aout.c: Derive new module from sunos.c, containing generic
1163 support code for all kinds of a.out files.
1165 * sunos.c: Remove all code that goes in aout.c. Split out
1166 machine dependent followup in sunos4_object_p into
1167 sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
1168 and redefine only the names we CHANGE, not all the names. Drop
1169 the little-endian vector, and rename the vector as sunos4 rather
1172 * b.out.c: Use aout.c routines for most of the work. Slight
1173 changes for the new regime. Remove close_and_cleanup and
1174 get_section_contents in favor of generics. New transfer vector
1177 * newsos.c: New support for Sony NEWS, another a.out format.
1179 * ecoff.c: Remove close_and_cleanup. New tvec regime.
1180 * icoff.c, m88k-bcs.c: Add write_contents to tvec.
1181 * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
1183 * opncls.c (bfd_close): Call format-dependent write_contents
1184 routine, if writing, before calling target-dependent
1185 close_and_cleanup routine (which is now always generic, I think).
1186 * srec.c: Use bfd_alloc instead of malloc. Remove
1187 close_and_cleanup and move code from it to
1188 srec_write_object_contents. Add write_contents to tvec.
1189 * targets.c: Remove a.out little vector, replace a.out big
1190 vector with SunOS vector. FIXME: Need Vax support again now.
1192 * libbfd.h: Add write_contents format-dependent-vector to the
1193 bfd_target vector. Supply a generic close_and_cleanup routine.
1194 * liba.out.h: Handle the new aout.c split. Add prototypes for
1195 all routines defined in aout.c. Rename "sunos" things to "aout"
1196 things. Add a few fields where needed for various formats.
1197 * Makefile.in: Add aout.c and newsos.c.
1199 * archive.c, ieee.c, oasys.c: Lint.
1201 Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1204 changed forward declaration struct stat; to reduce warnings. Changed
1205 comment on bfd_h_<x>_x.
1207 * ../include/m68kcoff.h, ../include/intel-coff.h,
1208 ../include/m88k-bcs.h
1209 Now there are two incarnations of relocs, linenos and syments. One for
1210 internal digestion, and one full of char arrays for I/O. The original
1211 names have gone to detect errors.
1213 * Makefile.in, m68kcoff.c, targets.c
1214 Test new structure code with a 68k coff implementaion
1216 * coff-code.h, icoff.c, coffswap.c, libcoff.h
1217 Fixed all the places where there were problems with the size and
1218 alignments of structures on disk and structures in memory. #ifed out
1219 all the code in coffswap.c, since it should be done using the target
1222 Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1224 * ieee.c (do_one, ieee_slurp_section_data): now supports the load
1225 multiple reloc command.
1227 * sunos.c (sunos4_set_section_contents): Made it so that sections
1228 are always padded to their alignment size.
1230 Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1232 * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
1233 Clean up types and such (saber C problems).
1234 * ecoff.c: Clean up types and such. Remove routines that are
1235 not used. Fix up reading and swapping of shorts from files.
1237 Notes on bfd-0.5.2-patch1a, from Per Bothner:
1239 * a.out.vax.c: Remove two bogus "static" from prototypes.
1241 * ecoff.c: Got rid of lots of non-working junk (that had
1242 been copied directly from coff-code.h).
1243 Updated to be consistent with updates to icoff.c and coff-code.h.
1245 * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
1246 if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
1248 * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
1249 but until the target_vector is automatically generated,
1250 it's as good as any. Note that the text offset is the only
1251 difference between NewsOS and SunOs (including magic numbers).
1252 (Most of the sunos_* routines should to renamed bsd_*
1253 and move to a bsd.c file. Then (and when the target_vector
1254 is automatically generated) it might make sense to create
1255 a separate Sony target.)
1257 * sysdep.h: Don't declare fread and fwrite. Causes trouble
1258 on some systems, and doesn't help on others.
1259 Similarly, only define X_OK if not already defined.
1261 * trad-core.c: Don't include sys/stat.h - at least
1262 on NewsOS 3, it has already been included.
1264 Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1266 * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
1267 bfd_coff_swap_lineno): Export the routines that byte-swap COFF
1268 symbol tables if necessary when reading them in, so gdb can use
1269 them. Add "bfd_coff_" to the names so they won't conflict with
1270 names in calling programs. FIXME-soon: if coff-code.h is
1271 included in two BFD modules, this will cause duplicate
1272 definitions; the routines should be exported to a separate,
1273 common, module (probably along with a mess of other ones).
1275 Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1277 Improve modtime support.
1279 * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
1280 Remove #define for bfd_get_mtime. Remove gratuitous comment.
1281 * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
1282 BUG: archive members still do not get correct mod times.
1284 Improve floating point support for core files.
1286 * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
1287 (sunos4_core_file_p): Create a second registers section in the
1288 core file, called ".reg2", for the float registers.
1290 Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1292 * many changes to improve archive handling; found a logic flaw in
1293 bfd_check_format which only just happened to work by cooncidence.
1295 Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1297 * bfd.c (bfd_perform_relocation): fixed to use output_offsets
1300 * bfd.h: changed type of udata in asymbol to void *, like it
1301 should be. Added bfd_reloc_dangerous enum member.
1303 * coff-code.h: Fixed it so that internally generated symbols get
1304 their values relocated correctly in all cases. Removed calls to
1307 * icoff.c: Not understanding the destination symbol of a reloc is
1308 not a failure any more, just 'dangerous'. This allows linking of
1309 b.out and coff images.
1311 * sunos.c: Cleaned up the way that ZMAGIC section sizes are
1315 Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1317 * sunos.c (translate_to_native_sym_flags): fixed
1318 sym_pointer->n_value so that symbols on the way out get their
1319 section relative values calculated correctly.
1321 * coff-code.h (mangle_symbols): fixed problem where tags were not
1322 being relocated for structs, enums, unions. Also various lints.
1324 Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1326 * archive.c (get_elt_at_filepos): system_call_error returned
1329 Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
1331 * Resolve the use of no_error and system_call_error.
1332 The bfd library itself now will never set bfd_error to
1335 The code still needs to be combed to make sure all the error
1336 codes are correct. I suspect they are not always set correctly.
1338 * The names of all the messages have _ prepended because the sun
1339 bundled compiler can't distinguish from a macro which takes an
1340 argument and the same identifier in a non-macro context.
1342 * The reason for the above being that entry points which used to
1343 be trampoline functions are now just macros which expand to a
1344 direct call through the bfd's xfer vector.
1346 * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
1347 must gas have its own version of everything (the gas version
1348 had the correct value)
1350 Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
1352 * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
1353 properly support i960 architecture and output correct reloc stuff.
1355 * bfd.h: added prototype for bfd_printable_arch_mach, added
1358 * coff-code.h: Applied patches from chrisb to support i960
1359 architecture, zero relocs and swap them correcly and conditionally
1360 compiled the timestamp.
1362 * sunos.c: Made the default section alignment 2^3 so that doubles
1363 are done properly. Fixed the same reloc bug that was in b.out.c
1365 * sysdep.h: Now compiles on a Posix box
1367 Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1369 * icoff.c: Fix comment on big-endian version.
1370 * coff-code.h: Make HAS_RELOC really work (it's backwards from
1371 F_RELFLG). Set F_AR32WR in output files if little endian
1374 Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
1376 * archures.c fixed =/== typo
1378 * sunos.c added architecture stuff for output. Fixed
1379 bug where files where vma(data) != size(text)
1380 were processed wrong.
1382 * coff-code.h added a lint cast
1384 * (../include/a.out.sun4.h) fixed it so zmagic
1387 Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
1389 * archive.c removed loads of includes, and fixed bug where string
1390 table didn't have a null at the end.
1392 * bfd.c fixed includes, added symbols argument to
1393 canonicalize_reloc entry point.
1395 * libbfd.c fixed includes and added some lint patches.
1397 * targets.c added both sorts of intel coff.
1399 * b.out.c fixed included, changed was the canonical
1402 * icoff.c added support for callj and big and little
1405 * opncls.c added chmod+xing for files with EXEC_P set.
1407 * sunos.c fixed includes. Changed default section
1408 alignement to words. Fixed relocation stuff to work with
1411 * bfd.h various new types added, prototype for new
1412 reloc calls, changed bfd->iostream to a void *
1413 to including files don't need stdio.h.
1415 * libcoff.h added conversion table to tie relocs to
1420 * coff-code.h fixed includes. Added code to support
1421 big and little endian formats. Various lints. Better
1422 processing of symbols. Changed reloc stuff to new
1425 * libbfd.h fixed includes
1428 Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
1430 * bfd.h changed name of alignment entry in sec_struct to
1431 alignment_power, because of conflicting uses within bfd.
1432 Now it should be obvious that it's a 2**n alignment
1433 specifier. Removed start_pad, end_alignment, block, minsize,
1434 output_file_alignment, subsection_alignment and original_vma fields.
1435 Added align_power() macro. Fixed bfd_section_alignment
1436 acessor macros. Added bfd_symbol_same_target macro.
1438 * b.out.c (b_out_write_object_contents) fixed to use
1439 new alignment member. Fixed (callj_callback) to use section
1440 relative symbols properly.
1442 * sunos.c (sunos4_object_p) fixed to use new alignment_power.
1443 Fixed (translate_from_native_sym_flags) to correctly make
1444 symbols section relative.
1446 * bfd.c (bfd_errmsg) fixed various enum cast problems.
1447 (bfd_make_section) took out initialization of obsolete members.
1448 (bfd_print_symbol_vandf) added
1450 * opncls.c (bfd_create) created.
1452 * coff-code.h (coff_new_section_hook) took away refs
1453 to obsolete members. (make_a_section_from_file) added
1454 conversion between alignment types. (coff_symbol_from)
1455 added. (coff_count_linenumbers) only counts linenumbers
1456 if symbol is of coff-type. (coff_mangle_symbols) only
1457 heavily mangles symbols if symbol is coff-type.
1458 (coff_write_symbols) various lints. (coff_write_object_contents)
1459 various lints and modification for alignment conversion.
1460 (coff_slurp_relocs) fixed for use with new asection shape.
1462 Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
1464 * archive.c lots of lint
1466 * b.out.c added callj relocation support, upgrated reloc howto.
1467 Fixed so that asymbol and reloc records are output
1470 * bfd.c lots of lint, support for new bfd entry point
1473 * bfd.h changed definition of asymbol to contain pointer to
1474 owning bfd, removed target dependencies.
1476 * cache.c took out print statements, put in BFD_ASSERT calls.
1478 * coff-code.h various lints, corrected linenumber output
1479 functionality. Added support for new style asymbols and
1480 bfd_print_symbol. Fixed so that asymbol and
1481 reloc records are handled correctly. Added timestamp.
1483 * icoff.c Added support for new howto shape.
1485 * liba.out.h Added support for new asymbol shape
1487 * libbfd.c various lints
1489 * libbfd.h various lints
1491 * libcoff.h added support for new asymbol shape.
1493 * sunos.c various lints. Added support for new asymbol shape
1494 and bfd_print_symbol.

1498 * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
1499 pointer lint. Added support for callj relocation. Fixed bug where
1500 the last 32 bytes of the text section were overwritten by data. Fixed bug
1501 where archives of b.out didn't work due bfd_slurp_extended_name_table
1504 * sunos.c added support for n_other field. Braced the howto table so
1505 that it won't be affected by any lengthing of the howto struct typedef.
1508 * bfd.h added support for n_other field, added special_function
1509 reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
1512 * bfd.c upgraded bfd_perform_relocation, various lints.

1516 * ChangeLog: Started ChangeLog for BFD.
1517 * ToDo: Create file for suggestions.
1519 * Makefile: Support easy loading into Saber C.
1520 Add dependencies for icoff.o and bcs88kcoff.o.
1521 Rename coff.c to coff-code.h. Change callers.
1523 * bfd.c (bfd_check_format): Allow the check_format routines
1524 to return the desired target vector, rather than just a Boolean.
1525 bfd.h (bfd_check_format): Change function pointer return type.
1526 archive.c (bfd_generic_archive_p): change callee.
1527 b.out.c (b_out_little_object_p, b_out_big_object_p,
1528 b_out_real_object_p): change callee.
1529 libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
1530 in check_format transfer vectors that need a filler.
1531 libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
1532 bcs88kcoff.c: change callee.
1533 coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
1534 icoff.c: change callee.
1535 sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
1537 * libbfd.c (zalloc): It should actually zero the storage!
1538 This was commented out for some reason.
1540 * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
1541 This is so callers can avoid <stdlib.h> which doesn't exist
1544 * bfd.c (map_over_sections): Add debugging code, since I
1545 noticed the section count for sunos core files was bad, but only
1546 GDB had detected the problem.
1547 (bfd_set_section_lineno_size, bfd_set_section_linenos,
1548 bfd_get_section_linenos): Remove obsolete functions.
1549 (bfd_apply_relocations): Use longs, not ints, for the math.
1551 * bfd.h: Declare enum boolean and struct bfd_target as well
1552 as typedefs for them. Remove obsolete
1553 bfd_get_section_lineno_size.
1555 * cache.c: Make the "fdopen" support work. Keep better track
1556 of how many files are open. Centralize the opening of files
1557 and be sure bfd_open[rw] actually try to open the file. Evade
1558 linked list initialization problems.
1560 * b.out.c, coff-code.h, opncls.c, sunos.c: lint.
1562 * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
1564 * cplus-dem.c: Delete file, since it is not part of BFD.
1566 * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
1567 (bfd_openr, bfd_openw): Actually open the file, give error now.
1569 * sunos.c (sunos4_core_file_p): Set section count.
1570 (sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
1571 obsolete definitions.
1572 (_write_symbol_table): Initialize <idx> counter.
1573 (foop): Eliminate debugging code.
