3035 fields in the exec header to zero. Update fields in the exec
3036 header as sizes of loadable subspaces are computed. Carefully
3037 preserve alignments when building executables. Actually write the
3038 exec after all the fields are filled in.
3040 * Better long-filename handling. Reads SOM ABI compliant extended
3041 names, but doesn't quite write compliant extended names yet.
3042 * som.c (som_slurp_extended_name_table): Delete function. The
3043 generic code will handle things correctly.
3044 (som_slurp_armap): Seek to the beginning of the next member.
3045 (normalize): New function.
3046 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3047 name table into account when computing the file offsets in the
3048 SOM dictionary. Make sure to align to an even boundary.
3049 (som_write_armap): Initialize the checksum to zero.
3050 (ar_maxchars): Fix. Opps.
3052 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3054 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3055 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3057 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3059 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3060 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3061 * bfd-in2.h: Regenerated.
3063 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3064 this was also named trad_unix_bfd_copy_private_bfd_data.
3066 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3068 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3069 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3070 returns NULL, it is not an error. It's possible that some of
3071 these checks are not necessary (because the size can never be
3072 zero), but putting in the checks is the conservative thing to do
3073 in light of the fact that some of these malloc calls replaced
3074 unchecked alloca calls, in which a zero argument would work fine.
3076 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3078 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3079 duplicate definition.
3080 (osf_core_bfd_is_local_label): Define.
3082 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3083 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3084 failure indication, it merely means there are no relocs.
3086 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3087 after NAME, since SunOS /bin/cc can't handle it.
3089 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3091 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3092 From sukes@glue.umd.edu (Tasuki Hirata).
3094 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3096 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3097 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3098 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3100 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3102 * som.c (som_prep_for_fixups): Detect section symbols based
3103 on either the lack of private data or the symbol flags. Do not
3104 munge section symbol names anymore -- they no longer confuse GDB.
3105 (som_begin_writing): Leave space for an exec header if writing
3107 (som_slurp_symbol_table): Recognize both forms of section symbol
3108 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3109 section symbols to be the name of the section they represent.
3110 Debugging symbols begin with "L$0\001", not just "L$".
3112 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3114 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3116 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3117 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3118 and bfd_is_local_label.
3120 * targets.c: Add new entries to the bfd_target structure.
3122 * bfd.c (bfd_copy_private_bfd_data): New definition.

3133 the target vector which all point to bfd_false.
3135 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3136 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3137 Default new vectors for copying private backend data to bfd_true.
3138 Default new vector for determining if a symbol is a local label
3139 to bfd_generic_is_local_label.
3141 * som.c (som_bfd_copy_private_section_data): New function.
3142 (som_bfd_is_local_label): New function.
3143 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3145 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3147 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3149 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3151 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3154 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3155 Indent some of them to GNU standards.
3157 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3158 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3159 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3160 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3161 Update copyright years.
3163 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3165 * som.c (som_prep_for_fixups): A relocation involving the section
3166 symbol for the *ABS* section is really a relocation involving
3168 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3169 undefined symbols. Correctly distinguish between debugger symbols
3170 and section symbols.
3172 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3173 for spaces and subspaces.
3175 * som.c (som_bfd_count_ar_symbols): Fix typo.
3177 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3178 HAS_RELOC based on the object's magic number.
3179 (make_unique_section): Delete function. BFD and its users are
3180 prepared to handle multiple sections with the same name.
3181 (setup_sections): Allocate space on the BFD's obstack to hold
3182 section names. Use bfd_make_setion_anyway rather than the
3183 obsolete make_unique_section.
3184 (som_prep_headers): Choose the correct SOM magic number based
3186 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3188 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3190 * elf32-ppc.c: Renamed from elf32-powerpc.c.

3200 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3201 is always located at the start of the data section to allow
3202 recovery of the dynamic info from a stripped executable.

3206 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3208 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3209 cruft (like the #pragma alloca for AIX).
3210 In addition to that problem, the C alloca calls xmalloc, which
3211 means checking for being out of memory can't work right. The
3212 following changes remove all uses of alloca from BFD.
3213 * hosts/solaris2.h: Remove alloca cruft.
3214 * som.c: Replace alloca with a fixed size auto array.
3215 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

3217 sunos.c: Replace alloca with malloc and appropriate error checking and
3219 * linker.c: Replace alloca with obstack_alloc.
3220 * libbfd.h: Rebuilt.
3222 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3224 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3227 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3229 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3230 Elf*_Off typedefs by their expansion, the typedefs have been
3231 removed from include/elf/internal.h.
3232 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3233 SHT_PROGBITS section.
3235 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3237 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3244 return from bfd_seek indicates an error.
3245 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3246 TRAD_CORE_STACK_OFFSET.
3247 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3248 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3250 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3252 * som.[ch]: Do not include libhppa.h in som.c, instead include
3255 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3256 include it in elf32-hppa.h.
3258 * som.c (log2): Return -1 on error rather than aborting.
3259 (setup_sections): Bubble up an error from log2.
3261 * Changes to make HP C compiler happy in both traditional
3263 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3265 (bfd_som_set_section_attributes): Use unsigned int rather than
3266 unsigned char to avoid GNU-C extensions.
3267 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3268 or failure rather than aborting on failure.
3270 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3272 (bfd_som_attach_aux_hdr): Add prototype.
3273 (hppa_som-gen_reloc_type): Likewise.

3311 Set reloc->sym_ptr_ptr appropriately.
3312 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3313 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3314 argument. Use the output symbols when canonicalizing the relocs,
3315 creating them if necessary.
3317 * linker.c (_bfd_generic_link_output_symbols): Do not
3318 rebuild/clobber the output symbols if they already exist.
3320 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3322 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

3332 PARAMize and staticize rest of functions. Delete unused
3333 functions. Delete unused/unnecessary arguments to some functions.

3335 error code propogation working. Work on spacing and indention.
3336 Add FIXMEs for unresolved problems. Use enums rather than
3337 #defines for lots of things. Merge two functions which build
3338 linker stubs into a single function (so they can easily share a
3339 ton of common code).
3341 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3343 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3344 avoid depending upon right shifts of signed numbers, and to
3345 correct handling of src_mask with lower bits zero.

3376 (elf_hppa_tc_make_sections): Likewise.
3377 (elf_hppa_final_processing): Add extern decl.
3379 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3380 comments. PARAMize some static functions. Delete unused functions.

3382 static vars together. Collapse common case statements together
3383 in many places. Use default case when possible instead of listing
3384 each case separately. Abort for bad errors until we get error
3385 code propogation working. Work on spacing and indention problems.
3386 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3387 COMPLEX relocation support (it's never used anyway).
3388 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3389 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3390 (elf_hppa_tc_make_sections): Likewise.

3431 * elfcode.h (alloca): Delete declaration.
3433 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
3434 number rather than HP9000S800_ID. Note som.c is careful
3435 to make sure CPU_PA_RISC1_0 is always defined.
3437 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
3439 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

3456 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
3457 operation to avoid OSF 1.3 cc bug.
3458 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
3459 and bss_size bfd_size_type instead of unsigned long. Make
3460 text_start and data_start bfd_vma instead of unsigned long.

4129 bfd_som_set_subsection_attributes): Change parameters from char
4130 to int. Following a prototype with an old-style function definition

4237 use get_value to get the symbol value and check for undefined
4239 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4240 undefined, look it up in the linker hash table.
4242 * aoutx.h (translate_symbol_table): The string index 0 has a

4267 The sparc (and possibly other?) NLM format requires a different
4268 way to write exports, so add a write_export field to the backend
4269 data (and set it to NULL for everything but the sparc).

4319 read_dynamic_relocs fields.
4320 * aout-target.h (MY(backend_data)): Initialize
