3025 (_bfd_generic_final_link): Likewise.
3026 (_bfd_generic_link_output_symbols): Likewise.

3029 in asymbol udata field.
3031 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3033 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3034 reloc, used in embedded PIC code.
3035 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

3042 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3043 add_symbls entry point.
3045 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3046 counting relocs. Set SEC_RELOC flag for any section which has

3051 * linker.c (_bfd_generic_link_add_symbols): Just call
3052 generic_link_add_symbols.
3053 (_bfd_generic_link_add_symbols_collect): New function, like
3054 _bfd_generic_link_add_symbols but also collect constructors and
3055 destructors by name as collect2 does.
3056 (generic_link_add_symbols): New function, like old
3057 _bfd_generic_link_add_symbols but with collect argument.
3058 (generic_link_add_object_symbols): Take collect argument.

3070 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
3071 for first character in an extended name.
3072 (_bfd_write_archive_contents): If ar_padchar == '/', then use
3073 "//" as the name of the special archive member holding the
3074 extended name table.
3076 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3078 Support for link_order types which generate relocs in order to
3079 support -Ur in the linker.
3080 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3081 from call to _bfd_generic_link_add_one_symbol.
3082 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3083 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3084 instead of bitsize to add_to_set call back.
3085 (_bfd_generic_final_link): Account for link_order relocs when
3086 allocating space for relocations. Handle them in link_order loop.
3087 (_bfd_generic_reloc_link_order): New function.
3088 (_bfd_default_link_order): If a reloc_link_order is seen here,
3090 (_bfd_count_link_order_relocs): New function.
3091 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3092 argument from declaration.
3093 (_bfd_generic_reloc_link_order): Declare.
3094 (_bfd_count_link_order_relocs): Declare.

3096 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3097 call to _bfd_generic_link_add_one_symbol.

3103 call to _bfd_generic_link_add_one_symbol.
3104 (ecoff_bfd_final_link): Account for link_order relocs when
3105 allocating space for relocations. Handle them in link_order loop.
3106 (ecoff_link_write_external): Set the storage class of a defined
3107 linker created symbol based on the section it is in. Correct
3108 bfd_link_hash_weak case to use .sc rather than .st.
3109 (ecoff_reloc_link_order): New function.
3110 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3112 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3121 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3123 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3125 * som.c (bfd_section_from_som_symbol): Only to do the value
3126 comparison for function symbols within executables.
3128 * som.c (bfd_section_from_som_symbol): Renamed from
3129 som_section_from_subspace_index. Pass in a native SOM symbol.
3130 For executables, iterate through the sections to find out
3131 which contains the symbol's address rather than using the
3132 symbol_info field. (symbol_info has a different meaning for
3133 dynamicly linked executables.)
3135 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3138 * som.c (som_begin_writing): Fix braino (one call to align
3139 space/subspace data was done unconditionally rather than
3140 just for executables.)
3142 * som.c (som_begin_writing): Align text in all executables to
3143 make HPUX kernel happy. Fixes strip/objcopy for shared
3146 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3148 * som.c (som_begin_writing): Account for alignment needs of
3149 subspaces too when writing executables. Never request a negative
3150 bss size. Fixes some problems with demand paged executables,
3151 still having problems with pure executables and shared executables.
3153 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3155 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3156 bfd_zalloc for rawptr, because later on we may call free, not
3159 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3160 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3161 * cisco-core.c: New file.
3162 * Makefile.in: Change accordingly.
3163 * configure.in: Recognize cisco_core_vec.
3164 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3165 * targets.c: Add cisco_core_vec.
3166 * bfd-in2.h: Rebuilt.
3168 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3170 * som.h (som_copyable_section_data_struct): New structure
3171 containing all the private section information which needs
3172 to be copied from input section to output section during
3174 (som_section_data_struct): Remove several fields now in
3175 som_copyable_section_data_struct. Make the space and
3176 subspace dictionaries be pointers (to save space when
3177 only reading objects).
3179 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3180 some references changed. Allocate a copyable data stucture if
3181 none exists. Store info into the copyable data structure.
3182 (bfd_som_set_subsection_attributes): Likewise.
3183 (som_is_space, som_is_subspace, som_is_container): New functions.
3184 Use these instead of directly accessing private data.
3185 (som_prep_headers): Allocate space and subspace headers here.
3186 Fill in some fields in the space/subspace headers from the
3188 (som_bfd_copy_private_section_data): Only copy the stuff
3189 that we really need to make objcopy and strip work. Allocate
3190 the copy_data structure for the output bfd before copying.
3192 * som.h (struct som_exec_data): New structure to hold exec
3193 info that must be preserved when running objcopy/strip.
3194 (struct somdata): Add new "exec_data" field and accessor
3195 macro. Add some comments on how the various fields are used.
3196 (som_section_data_struct): Make is_space and is_subspace bitfields.
3197 Delete unused subspace_index. All references now use the
3198 target_index field within the section structure itself.
3200 * som.c (make_unique_section): Delete unused declaration.
3201 (som_bfd_copy_private_bfd_data): New function.
3202 (som_object_setup): Allocate space for and save exec information
3203 that needs to be copied during objcopy/strip.
3204 (som_mkobject): Do not allocate space for a file header here.
3205 It is not used when only reading SOM objects.
3206 (som_prep_headers): Allocate space for and attach a file header
3207 to the output bfd. For executables, use the saved system_id
3208 value rather than trying to guess the right value. Do not abort
3209 wwhen setting file_hdr->entry* for executables.
3210 (som_begin_writing): For executables, set the exec_entry and
3212 (som_copy_private_backend_section_data): Always return a value.
3214 * libhppa.h (PA_PAGESIZE): Define.
3216 * som.c (SOM_ALIGN): Define.
3217 (som_begin_writing): If writing an executable, initialize all
3218 fields in the exec header to zero. Update fields in the exec
3219 header as sizes of loadable subspaces are computed. Carefully
3220 preserve alignments when building executables. Actually write the
3221 exec after all the fields are filled in.
3223 * Better long-filename handling. Reads SOM ABI compliant extended
3224 names, but doesn't quite write compliant extended names yet.
3225 * som.c (som_slurp_extended_name_table): Delete function. The
3226 generic code will handle things correctly.
3227 (som_slurp_armap): Seek to the beginning of the next member.
3228 (normalize): New function.
3229 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3230 name table into account when computing the file offsets in the
3231 SOM dictionary. Make sure to align to an even boundary.
3232 (som_write_armap): Initialize the checksum to zero.
3233 (ar_maxchars): Fix. Opps.
3235 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3237 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3238 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3240 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3242 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3243 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3244 * bfd-in2.h: Regenerated.
3246 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3247 this was also named trad_unix_bfd_copy_private_bfd_data.
3249 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3251 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3252 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3253 returns NULL, it is not an error. It's possible that some of
3254 these checks are not necessary (because the size can never be
3255 zero), but putting in the checks is the conservative thing to do
3256 in light of the fact that some of these malloc calls replaced
3257 unchecked alloca calls, in which a zero argument would work fine.
3259 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3261 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3262 duplicate definition.
3263 (osf_core_bfd_is_local_label): Define.
3265 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3266 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3267 failure indication, it merely means there are no relocs.
3269 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3270 after NAME, since SunOS /bin/cc can't handle it.
3272 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3274 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3275 From sukes@glue.umd.edu (Tasuki Hirata).
3277 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3279 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3280 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3281 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3283 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3285 * som.c (som_prep_for_fixups): Detect section symbols based
3286 on either the lack of private data or the symbol flags. Do not
3287 munge section symbol names anymore -- they no longer confuse GDB.
3288 (som_begin_writing): Leave space for an exec header if writing
3290 (som_slurp_symbol_table): Recognize both forms of section symbol
3291 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3292 section symbols to be the name of the section they represent.
3293 Debugging symbols begin with "L$0\001", not just "L$".
3295 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3297 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3299 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3300 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3301 and bfd_is_local_label.
3303 * targets.c: Add new entries to the bfd_target structure.
3305 * bfd.c (bfd_copy_private_bfd_data): New definition.
3307 * section.c (bfd_copy_private_section_data): New definition.
3309 * syms.c (bfd_is_local_label): New definition.
3311 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3313 * libbfd.c (bfd_generic_is_local_label): New function.
3315 * *-core.c: Provide default definitions for new functions in
3316 the target vector which all point to bfd_false.
3318 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3319 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3320 Default new vectors for copying private backend data to bfd_true.
3321 Default new vector for determining if a symbol is a local label
3322 to bfd_generic_is_local_label.
3324 * som.c (som_bfd_copy_private_section_data): New function.
3325 (som_bfd_is_local_label): New function.
3326 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3328 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3330 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3332 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3334 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3337 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3338 Indent some of them to GNU standards.
3340 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3341 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3342 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3343 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3344 Update copyright years.
3346 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3348 * som.c (som_prep_for_fixups): A relocation involving the section
3349 symbol for the *ABS* section is really a relocation involving
3351 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3352 undefined symbols. Correctly distinguish between debugger symbols
3353 and section symbols.
3355 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3356 for spaces and subspaces.
3358 * som.c (som_bfd_count_ar_symbols): Fix typo.
3360 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3361 HAS_RELOC based on the object's magic number.
3362 (make_unique_section): Delete function. BFD and its users are
3363 prepared to handle multiple sections with the same name.
3364 (setup_sections): Allocate space on the BFD's obstack to hold
3365 section names. Use bfd_make_setion_anyway rather than the
3366 obsolete make_unique_section.
3367 (som_prep_headers): Choose the correct SOM magic number based
3369 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3371 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3373 * elf32-ppc.c: Renamed from elf32-powerpc.c.

3383 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3384 is always located at the start of the data section to allow
3385 recovery of the dynamic info from a stripped executable.
3386 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3389 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3391 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3392 cruft (like the #pragma alloca for AIX).
3393 In addition to that problem, the C alloca calls xmalloc, which
3394 means checking for being out of memory can't work right. The
3395 following changes remove all uses of alloca from BFD.
3396 * hosts/solaris2.h: Remove alloca cruft.
3397 * som.c: Replace alloca with a fixed size auto array.

3402 * linker.c: Replace alloca with obstack_alloc.
3403 * libbfd.h: Rebuilt.
3405 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3407 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3410 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3412 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3413 Elf*_Off typedefs by their expansion, the typedefs have been
3414 removed from include/elf/internal.h.
3415 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3416 SHT_PROGBITS section.
3418 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3420 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3424 * configure.host: Recognize i[34]86-sequent-*.
3426 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3427 return from bfd_seek indicates an error.
3428 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3429 TRAD_CORE_STACK_OFFSET.
3430 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3431 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3433 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3435 * som.[ch]: Do not include libhppa.h in som.c, instead include
3438 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3439 include it in elf32-hppa.h.
3441 * som.c (log2): Return -1 on error rather than aborting.
3442 (setup_sections): Bubble up an error from log2.
3444 * Changes to make HP C compiler happy in both traditional
3446 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3448 (bfd_som_set_section_attributes): Use unsigned int rather than
3449 unsigned char to avoid GNU-C extensions.
3450 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3451 or failure rather than aborting on failure.
3453 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3455 (bfd_som_attach_aux_hdr): Add prototype.
3456 (hppa_som-gen_reloc_type): Likewise.
3458 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3459 (hppa_look_for_stubs_in_section): Do not return false on failure
3460 until rest of code is ready to handle it. Abort for now.

3570 COMPLEX relocation support (it's never used anyway).
3571 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3745 (b_out_relax_section): If a section contains no relocations, don't
3746 bother processing them.
3747 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4450 The sparc (and possibly other?) NLM format requires a different
4451 way to write exports, so add a write_export field to the backend
4452 data (and set it to NULL for everything but the sparc).
