113 for first character in an extended name.
114 (_bfd_write_archive_contents): If ar_padchar == '/', then use
115 "//" as the name of the special archive member holding the
118 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
120 Support for link_order types which generate relocs in order to
121 support -Ur in the linker.

123 from call to _bfd_generic_link_add_one_symbol.
124 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
125 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
126 instead of bitsize to add_to_set call back.
127 (_bfd_generic_final_link): Account for link_order relocs when
128 allocating space for relocations. Handle them in link_order loop.
129 (_bfd_generic_reloc_link_order): New function.

165 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
167 * som.c (bfd_section_from_som_symbol): Only to do the value
168 comparison for function symbols within executables.
170 * som.c (bfd_section_from_som_symbol): Renamed from
171 som_section_from_subspace_index. Pass in a native SOM symbol.
172 For executables, iterate through the sections to find out
173 which contains the symbol's address rather than using the
174 symbol_info field. (symbol_info has a different meaning for
175 dynamicly linked executables.)
177 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
180 * som.c (som_begin_writing): Fix braino (one call to align
181 space/subspace data was done unconditionally rather than
182 just for executables.)
184 * som.c (som_begin_writing): Align text in all executables to
185 make HPUX kernel happy. Fixes strip/objcopy for shared
188 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
190 * som.c (som_begin_writing): Account for alignment needs of
191 subspaces too when writing executables. Never request a negative
192 bss size. Fixes some problems with demand paged executables,
193 still having problems with pure executables and shared executables.
195 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
197 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
198 bfd_zalloc for rawptr, because later on we may call free, not
201 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
202 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
203 * cisco-core.c: New file.

208 * bfd-in2.h: Rebuilt.
210 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
212 * som.h (som_copyable_section_data_struct): New structure
213 containing all the private section information which needs
214 to be copied from input section to output section during
216 (som_section_data_struct): Remove several fields now in
217 som_copyable_section_data_struct. Make the space and
218 subspace dictionaries be pointers (to save space when
219 only reading objects).
221 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
222 some references changed. Allocate a copyable data stucture if
223 none exists. Store info into the copyable data structure.
224 (bfd_som_set_subsection_attributes): Likewise.
225 (som_is_space, som_is_subspace, som_is_container): New functions.
226 Use these instead of directly accessing private data.
227 (som_prep_headers): Allocate space and subspace headers here.
228 Fill in some fields in the space/subspace headers from the
230 (som_bfd_copy_private_section_data): Only copy the stuff
231 that we really need to make objcopy and strip work. Allocate
232 the copy_data structure for the output bfd before copying.
234 * som.h (struct som_exec_data): New structure to hold exec
235 info that must be preserved when running objcopy/strip.
236 (struct somdata): Add new "exec_data" field and accessor
237 macro. Add some comments on how the various fields are used.
238 (som_section_data_struct): Make is_space and is_subspace bitfields.
239 Delete unused subspace_index. All references now use the
240 target_index field within the section structure itself.
242 * som.c (make_unique_section): Delete unused declaration.
243 (som_bfd_copy_private_bfd_data): New function.
244 (som_object_setup): Allocate space for and save exec information
245 that needs to be copied during objcopy/strip.
246 (som_mkobject): Do not allocate space for a file header here.
247 It is not used when only reading SOM objects.
248 (som_prep_headers): Allocate space for and attach a file header
249 to the output bfd. For executables, use the saved system_id
250 value rather than trying to guess the right value. Do not abort
251 wwhen setting file_hdr->entry* for executables.
252 (som_begin_writing): For executables, set the exec_entry and
254 (som_copy_private_backend_section_data): Always return a value.
256 * libhppa.h (PA_PAGESIZE): Define.
258 * som.c (SOM_ALIGN): Define.
259 (som_begin_writing): If writing an executable, initialize all
260 fields in the exec header to zero. Update fields in the exec
261 header as sizes of loadable subspaces are computed. Carefully
262 preserve alignments when building executables. Actually write the
263 exec after all the fields are filled in.
265 * Better long-filename handling. Reads SOM ABI compliant extended
266 names, but doesn't quite write compliant extended names yet.
267 * som.c (som_slurp_extended_name_table): Delete function. The
268 generic code will handle things correctly.
269 (som_slurp_armap): Seek to the beginning of the next member.
270 (normalize): New function.
271 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
272 name table into account when computing the file offsets in the
273 SOM dictionary. Make sure to align to an even boundary.
274 (som_write_armap): Initialize the checksum to zero.
275 (ar_maxchars): Fix. Opps.
277 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
279 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
280 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
282 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
284 * bfd-in.h (BFD_VERSION): Use @VERSION@.
285 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
286 * bfd-in2.h: Regenerated.
288 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
289 this was also named trad_unix_bfd_copy_private_bfd_data.
291 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
293 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
294 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
295 returns NULL, it is not an error. It's possible that some of
296 these checks are not necessary (because the size can never be
297 zero), but putting in the checks is the conservative thing to do
298 in light of the fact that some of these malloc calls replaced
299 unchecked alloca calls, in which a zero argument would work fine.
301 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
303 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
304 duplicate definition.
305 (osf_core_bfd_is_local_label): Define.
307 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
308 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
309 failure indication, it merely means there are no relocs.
311 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
312 after NAME, since SunOS /bin/cc can't handle it.
314 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
316 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
317 From sukes@glue.umd.edu (Tasuki Hirata).
319 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
321 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
322 all that convoluted stuff with NAME, CAT3, etc. The convoluted
323 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
325 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
327 * som.c (som_prep_for_fixups): Detect section symbols based
328 on either the lack of private data or the symbol flags. Do not
329 munge section symbol names anymore -- they no longer confuse GDB.
330 (som_begin_writing): Leave space for an exec header if writing
332 (som_slurp_symbol_table): Recognize both forms of section symbol
333 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
334 section symbols to be the name of the section they represent.
335 Debugging symbols begin with "L$0\001", not just "L$".
337 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
339 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
341 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
342 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
343 and bfd_is_local_label.
345 * targets.c: Add new entries to the bfd_target structure.
347 * bfd.c (bfd_copy_private_bfd_data): New definition.
349 * section.c (bfd_copy_private_section_data): New definition.
351 * syms.c (bfd_is_local_label): New definition.

355 * libbfd.c (bfd_generic_is_local_label): New function.
357 * *-core.c: Provide default definitions for new functions in
358 the target vector which all point to bfd_false.
360 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
361 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
362 Default new vectors for copying private backend data to bfd_true.
363 Default new vector for determining if a symbol is a local label
364 to bfd_generic_is_local_label.
366 * som.c (som_bfd_copy_private_section_data): New function.
367 (som_bfd_is_local_label): New function.
368 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
370 * elf32-hppa.c (hppa_elf_is_local_label): New function.
372 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
374 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
376 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
379 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
380 Indent some of them to GNU standards.
382 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
383 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
384 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
385 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
386 Update copyright years.
388 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
390 * som.c (som_prep_for_fixups): A relocation involving the section
391 symbol for the *ABS* section is really a relocation involving
393 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
394 undefined symbols. Correctly distinguish between debugger symbols
397 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
398 for spaces and subspaces.
400 * som.c (som_bfd_count_ar_symbols): Fix typo.
402 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
403 HAS_RELOC based on the object's magic number.
404 (make_unique_section): Delete function. BFD and its users are
405 prepared to handle multiple sections with the same name.
406 (setup_sections): Allocate space on the BFD's obstack to hold
407 section names. Use bfd_make_setion_anyway rather than the
408 obsolete make_unique_section.
409 (som_prep_headers): Choose the correct SOM magic number based
411 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
413 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
415 * elf32-ppc.c: Renamed from elf32-powerpc.c.

425 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
427 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
428 is always located at the start of the data section to allow
429 recovery of the dynamic info from a stripped executable.
430 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
433 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
435 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
436 cruft (like the #pragma alloca for AIX).
437 In addition to that problem, the C alloca calls xmalloc, which
438 means checking for being out of memory can't work right. The
439 following changes remove all uses of alloca from BFD.
440 * hosts/solaris2.h: Remove alloca cruft.
441 * som.c: Replace alloca with a fixed size auto array.
442 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
443 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,

449 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
451 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
454 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
456 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
457 Elf*_Off typedefs by their expansion, the typedefs have been
458 removed from include/elf/internal.h.
459 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
460 SHT_PROGBITS section.
462 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
464 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
466 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
468 * configure.host: Recognize i[34]86-sequent-*.
470 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
471 return from bfd_seek indicates an error.
472 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
473 TRAD_CORE_STACK_OFFSET.
474 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
475 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

1497 The sparc (and possibly other?) NLM format requires a different
1498 way to write exports, so add a write_export field to the backend
1499 data (and set it to NULL for everything but the sparc).
