126 Support for link_order types which generate relocs in order to
127 support -Ur in the linker.

129 from call to _bfd_generic_link_add_one_symbol.
130 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
131 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
132 instead of bitsize to add_to_set call back.

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

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

361 * libbfd.c (bfd_generic_is_local_label): New function.
363 * *-core.c: Provide default definitions for new functions in
364 the target vector which all point to bfd_false.
366 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
367 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
368 Default new vectors for copying private backend data to bfd_true.
369 Default new vector for determining if a symbol is a local label
370 to bfd_generic_is_local_label.
372 * som.c (som_bfd_copy_private_section_data): New function.
373 (som_bfd_is_local_label): New function.
374 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
376 * elf32-hppa.c (hppa_elf_is_local_label): New function.
378 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
380 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
382 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
385 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
386 Indent some of them to GNU standards.
388 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
389 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
390 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
391 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
392 Update copyright years.
394 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
396 * som.c (som_prep_for_fixups): A relocation involving the section
397 symbol for the *ABS* section is really a relocation involving
399 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
400 undefined symbols. Correctly distinguish between debugger symbols
403 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
404 for spaces and subspaces.
406 * som.c (som_bfd_count_ar_symbols): Fix typo.

409 HAS_RELOC based on the object's magic number.
410 (make_unique_section): Delete function. BFD and its users are
411 prepared to handle multiple sections with the same name.
412 (setup_sections): Allocate space on the BFD's obstack to hold
413 section names. Use bfd_make_setion_anyway rather than the
414 obsolete make_unique_section.
415 (som_prep_headers): Choose the correct SOM magic number based
417 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
419 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
421 * elf32-ppc.c: Renamed from elf32-powerpc.c.

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

457 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
460 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
462 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
463 Elf*_Off typedefs by their expansion, the typedefs have been
464 removed from include/elf/internal.h.
465 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
466 SHT_PROGBITS section.
468 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
470 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
472 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
474 * configure.host: Recognize i[34]86-sequent-*.
476 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
477 return from bfd_seek indicates an error.
478 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace

885 check the result for NULL. Most set bfd_error to no_memory and

1287 _bfd_generic_link_write_global_symbol): Don't require that all

1503 The sparc (and possibly other?) NLM format requires a different
1504 way to write exports, so add a write_export field to the backend
1505 data (and set it to NULL for everything but the sparc).
