208 "//" as the name of the special archive member holding the
211 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
213 Support for link_order types which generate relocs in order to
214 support -Ur in the linker.

216 from call to _bfd_generic_link_add_one_symbol.
217 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.

219 instead of bitsize to add_to_set call back.
220 (_bfd_generic_final_link): Account for link_order relocs when
221 allocating space for relocations. Handle them in link_order loop.
222 (_bfd_generic_reloc_link_order): New function.

258 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
260 * som.c (bfd_section_from_som_symbol): Only to do the value
261 comparison for function symbols within executables.
263 * som.c (bfd_section_from_som_symbol): Renamed from
264 som_section_from_subspace_index. Pass in a native SOM symbol.
265 For executables, iterate through the sections to find out
266 which contains the symbol's address rather than using the
267 symbol_info field. (symbol_info has a different meaning for
268 dynamicly linked executables.)
270 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
273 * som.c (som_begin_writing): Fix braino (one call to align
274 space/subspace data was done unconditionally rather than
275 just for executables.)
277 * som.c (som_begin_writing): Align text in all executables to
278 make HPUX kernel happy. Fixes strip/objcopy for shared
281 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
283 * som.c (som_begin_writing): Account for alignment needs of
284 subspaces too when writing executables. Never request a negative
285 bss size. Fixes some problems with demand paged executables,
286 still having problems with pure executables and shared executables.
288 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
290 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
291 bfd_zalloc for rawptr, because later on we may call free, not

296 * cisco-core.c: New file.

301 * bfd-in2.h: Rebuilt.
303 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
305 * som.h (som_copyable_section_data_struct): New structure
306 containing all the private section information which needs
307 to be copied from input section to output section during
309 (som_section_data_struct): Remove several fields now in
310 som_copyable_section_data_struct. Make the space and
311 subspace dictionaries be pointers (to save space when
312 only reading objects).
314 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
315 some references changed. Allocate a copyable data stucture if
316 none exists. Store info into the copyable data structure.
317 (bfd_som_set_subsection_attributes): Likewise.
318 (som_is_space, som_is_subspace, som_is_container): New functions.
319 Use these instead of directly accessing private data.
320 (som_prep_headers): Allocate space and subspace headers here.
321 Fill in some fields in the space/subspace headers from the
323 (som_bfd_copy_private_section_data): Only copy the stuff
324 that we really need to make objcopy and strip work. Allocate
325 the copy_data structure for the output bfd before copying.
327 * som.h (struct som_exec_data): New structure to hold exec
328 info that must be preserved when running objcopy/strip.
329 (struct somdata): Add new "exec_data" field and accessor
330 macro. Add some comments on how the various fields are used.
331 (som_section_data_struct): Make is_space and is_subspace bitfields.
332 Delete unused subspace_index. All references now use the
333 target_index field within the section structure itself.
335 * som.c (make_unique_section): Delete unused declaration.
336 (som_bfd_copy_private_bfd_data): New function.
337 (som_object_setup): Allocate space for and save exec information
338 that needs to be copied during objcopy/strip.
339 (som_mkobject): Do not allocate space for a file header here.
340 It is not used when only reading SOM objects.
341 (som_prep_headers): Allocate space for and attach a file header
342 to the output bfd. For executables, use the saved system_id
343 value rather than trying to guess the right value. Do not abort
344 wwhen setting file_hdr->entry* for executables.
345 (som_begin_writing): For executables, set the exec_entry and
347 (som_copy_private_backend_section_data): Always return a value.
349 * libhppa.h (PA_PAGESIZE): Define.
351 * som.c (SOM_ALIGN): Define.
352 (som_begin_writing): If writing an executable, initialize all
353 fields in the exec header to zero. Update fields in the exec
354 header as sizes of loadable subspaces are computed. Carefully
355 preserve alignments when building executables. Actually write the
356 exec after all the fields are filled in.
358 * Better long-filename handling. Reads SOM ABI compliant extended
359 names, but doesn't quite write compliant extended names yet.
360 * som.c (som_slurp_extended_name_table): Delete function. The
361 generic code will handle things correctly.
362 (som_slurp_armap): Seek to the beginning of the next member.
363 (normalize): New function.
364 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
365 name table into account when computing the file offsets in the
366 SOM dictionary. Make sure to align to an even boundary.
367 (som_write_armap): Initialize the checksum to zero.
368 (ar_maxchars): Fix. Opps.
370 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
372 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
373 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
375 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
377 * bfd-in.h (BFD_VERSION): Use @VERSION@.
378 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
379 * bfd-in2.h: Regenerated.
381 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
382 this was also named trad_unix_bfd_copy_private_bfd_data.
384 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
386 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
387 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
388 returns NULL, it is not an error. It's possible that some of
389 these checks are not necessary (because the size can never be
390 zero), but putting in the checks is the conservative thing to do
391 in light of the fact that some of these malloc calls replaced
392 unchecked alloca calls, in which a zero argument would work fine.
394 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
396 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
397 duplicate definition.
398 (osf_core_bfd_is_local_label): Define.
400 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
401 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
402 failure indication, it merely means there are no relocs.
404 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
405 after NAME, since SunOS /bin/cc can't handle it.
407 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
409 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
410 From sukes@glue.umd.edu (Tasuki Hirata).
412 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
414 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
415 all that convoluted stuff with NAME, CAT3, etc. The convoluted
416 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
418 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
420 * som.c (som_prep_for_fixups): Detect section symbols based
421 on either the lack of private data or the symbol flags. Do not
422 munge section symbol names anymore -- they no longer confuse GDB.
423 (som_begin_writing): Leave space for an exec header if writing
425 (som_slurp_symbol_table): Recognize both forms of section symbol
426 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
427 section symbols to be the name of the section they represent.
428 Debugging symbols begin with "L$0\001", not just "L$".
430 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
432 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
434 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
435 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
436 and bfd_is_local_label.
438 * targets.c: Add new entries to the bfd_target structure.

451 the target vector which all point to bfd_false.
453 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
454 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
455 Default new vectors for copying private backend data to bfd_true.
456 Default new vector for determining if a symbol is a local label
457 to bfd_generic_is_local_label.
459 * som.c (som_bfd_copy_private_section_data): New function.
460 (som_bfd_is_local_label): New function.
461 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
463 * elf32-hppa.c (hppa_elf_is_local_label): New function.
465 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
467 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
469 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)

1590 The sparc (and possibly other?) NLM format requires a different
1591 way to write exports, so add a write_export field to the backend
1592 data (and set it to NULL for everything but the sparc).

2728 * elfcode.h (elf_object_p): Rather than looking through an array
2729 of architectures, get the ELF EM_xxx code from the backend
2730 information. Let the generic ELF target match any EM_xxx code not
