5116 dynamicly linked executables.)
5118 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5121 * som.c (som_begin_writing): Fix braino (one call to align

5159 subspace dictionaries be pointers (to save space when
5160 only reading objects).
5162 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5163 some references changed. Allocate a copyable data stucture if
5164 none exists. Store info into the copyable data structure.

5166 (som_is_space, som_is_subspace, som_is_container): New functions.
5167 Use these instead of directly accessing private data.

5169 Fill in some fields in the space/subspace headers from the
5171 (som_bfd_copy_private_section_data): Only copy the stuff
5172 that we really need to make objcopy and strip work. Allocate
5173 the copy_data structure for the output bfd before copying.

5176 info that must be preserved when running objcopy/strip.

5178 macro. Add some comments on how the various fields are used.
5179 (som_section_data_struct): Make is_space and is_subspace bitfields.

5188 It is not used when only reading SOM objects.
5189 (som_prep_headers): Allocate space for and attach a file header
5190 to the output bfd. For executables, use the saved system_id
5191 value rather than trying to guess the right value. Do not abort
5192 wwhen setting file_hdr->entry* for executables.
5193 (som_begin_writing): For executables, set the exec_entry and
5195 (som_copy_private_backend_section_data): Always return a value.
5197 * libhppa.h (PA_PAGESIZE): Define.

5200 (som_begin_writing): If writing an executable, initialize all
5201 fields in the exec header to zero. Update fields in the exec
5202 header as sizes of loadable subspaces are computed. Carefully
5203 preserve alignments when building executables. Actually write the
5204 exec after all the fields are filled in.
5206 * Better long-filename handling. Reads SOM ABI compliant extended
5207 names, but doesn't quite write compliant extended names yet.
5208 * som.c (som_slurp_extended_name_table): Delete function. The
5209 generic code will handle things correctly.
5210 (som_slurp_armap): Seek to the beginning of the next member.
5211 (normalize): New function.
5212 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5213 name table into account when computing the file offsets in the
5214 SOM dictionary. Make sure to align to an even boundary.
5215 (som_write_armap): Initialize the checksum to zero.

5226 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5227 * bfd-in2.h: Regenerated.
5229 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5230 this was also named trad_unix_bfd_copy_private_bfd_data.
5232 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5234 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5235 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5236 returns NULL, it is not an error. It's possible that some of
5237 these checks are not necessary (because the size can never be
5238 zero), but putting in the checks is the conservative thing to do
5239 in light of the fact that some of these malloc calls replaced
5240 unchecked alloca calls, in which a zero argument would work fine.
5242 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5244 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5245 duplicate definition.
5246 (osf_core_bfd_is_local_label): Define.
5248 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5249 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5250 failure indication, it merely means there are no relocs.
5252 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5253 after NAME, since SunOS /bin/cc can't handle it.
5255 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5257 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5258 From sukes@glue.umd.edu (Tasuki Hirata).
5260 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5262 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5263 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5264 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5266 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5268 * som.c (som_prep_for_fixups): Detect section symbols based
5269 on either the lack of private data or the symbol flags. Do not
5270 munge section symbol names anymore -- they no longer confuse GDB.
5271 (som_begin_writing): Leave space for an exec header if writing
5273 (som_slurp_symbol_table): Recognize both forms of section symbol
5274 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5275 section symbols to be the name of the section they represent.
5276 Debugging symbols begin with "L$0\001", not just "L$".
5278 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5283 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5284 and bfd_is_local_label.

5299 the target vector which all point to bfd_false.
5301 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5302 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5303 Default new vectors for copying private backend data to bfd_true.
5304 Default new vector for determining if a symbol is a local label
5305 to bfd_generic_is_local_label.
5307 * som.c (som_bfd_copy_private_section_data): New function.
5308 (som_bfd_is_local_label): New function.
5309 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5311 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5313 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5315 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5317 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5320 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5321 Indent some of them to GNU standards.
5323 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5324 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5325 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5326 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5327 Update copyright years.
5329 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5331 * som.c (som_prep_for_fixups): A relocation involving the section
5332 symbol for the *ABS* section is really a relocation involving
5334 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5335 undefined symbols. Correctly distinguish between debugger symbols
5336 and section symbols.
5338 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5339 for spaces and subspaces.
5341 * som.c (som_bfd_count_ar_symbols): Fix typo.
5343 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5344 HAS_RELOC based on the object's magic number.
5345 (make_unique_section): Delete function. BFD and its users are
5346 prepared to handle multiple sections with the same name.
5347 (setup_sections): Allocate space on the BFD's obstack to hold
5348 section names. Use bfd_make_setion_anyway rather than the
5349 obsolete make_unique_section.
5350 (som_prep_headers): Choose the correct SOM magic number based
5352 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

5372 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5374 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5375 cruft (like the #pragma alloca for AIX).
5376 In addition to that problem, the C alloca calls xmalloc, which
5377 means checking for being out of memory can't work right. The
5378 following changes remove all uses of alloca from BFD.
5379 * hosts/solaris2.h: Remove alloca cruft.
5380 * som.c: Replace alloca with a fixed size auto array.

5393 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5395 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5396 Elf*_Off typedefs by their expansion, the typedefs have been
5397 removed from include/elf/internal.h.
5398 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5399 SHT_PROGBITS section.

5412 TRAD_CORE_STACK_OFFSET.
5413 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5414 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

5418 * som.[ch]: Do not include libhppa.h in som.c, instead include
5421 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5422 include it in elf32-hppa.h.
5424 * som.c (log2): Return -1 on error rather than aborting.
5425 (setup_sections): Bubble up an error from log2.
5427 * Changes to make HP C compiler happy in both traditional
5429 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5431 (bfd_som_set_section_attributes): Use unsigned int rather than
5432 unsigned char to avoid GNU-C extensions.
5433 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5434 or failure rather than aborting on failure.
5436 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5438 (bfd_som_attach_aux_hdr): Add prototype.
5439 (hppa_som-gen_reloc_type): Likewise.

5479 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5480 argument. Use the output symbols when canonicalizing the relocs,
5481 creating them if necessary.
5483 * linker.c (_bfd_generic_link_output_symbols): Do not
5484 rebuild/clobber the output symbols if they already exist.

5502 Add FIXMEs for unresolved problems. Use enums rather than
5503 #defines for lots of things. Merge two functions which build
5504 linker stubs into a single function (so they can easily share a
5505 ton of common code).
5507 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5509 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5510 avoid depending upon right shifts of signed numbers, and to
5511 correct handling of src_mask with lower bits zero.

5543 (elf_hppa_final_processing): Add extern decl.
5545 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of

5550 each case separately. Abort for bad errors until we get error
5551 code propogation working. Work on spacing and indention problems.

5553 COMPLEX relocation support (it's never used anyway).
5554 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5555 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5556 (elf_hppa_tc_make_sections): Likewise.

5601 to make sure CPU_PA_RISC1_0 is always defined.
5603 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5605 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

6263 (only testing for m68k and vax at the moment); do verify that the
6264 preprocessor didn't trash the arch name inside the string version.

6295 bfd_som_set_subsection_attributes): Change parameters from char
6296 to int. Following a prototype with an old-style function definition

6403 use get_value to get the symbol value and check for undefined
6405 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6406 undefined, look it up in the linker hash table.
6408 * aoutx.h (translate_symbol_table): The string index 0 has a

6433 The sparc (and possibly other?) NLM format requires a different
6434 way to write exports, so add a write_export field to the backend
6435 data (and set it to NULL for everything but the sparc).
