3030 _bfd_generic_link_get_symbols and _bfd_generic_link_get_symcount
3031 to get the symbols from the BFD.
3032 (generic_link_check_archive_element): Likewise.
3033 (_bfd_generic_final_link): Likewise.
3034 (_bfd_generic_link_output_symbols): Likewise.

3037 in asymbol udata field.
3039 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3041 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3042 reloc, used in embedded PIC code.
3043 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

3048 relocs when allocating space for relocations. Set SEC_RELOC flag
3049 for any section which has relocs. Handle link_order relocs in
3050 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3051 add_symbls entry point.
3053 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3054 counting relocs. Set SEC_RELOC flag for any section which has

3059 * linker.c (_bfd_generic_link_add_symbols): Just call
3060 generic_link_add_symbols.
3061 (_bfd_generic_link_add_symbols_collect): New function, like
3062 _bfd_generic_link_add_symbols but also collect constructors and
3063 destructors by name as collect2 does.
3064 (generic_link_add_symbols): New function, like old
3065 _bfd_generic_link_add_symbols but with collect argument.
3066 (generic_link_add_object_symbols): Take collect argument.

3078 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
3079 for first character in an extended name.
3080 (_bfd_write_archive_contents): If ar_padchar == '/', then use
3081 "//" as the name of the special archive member holding the
3082 extended name table.
3084 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3086 Support for link_order types which generate relocs in order to
3087 support -Ur in the linker.
3088 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3089 from call to _bfd_generic_link_add_one_symbol.
3090 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3091 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3092 instead of bitsize to add_to_set call back.
3093 (_bfd_generic_final_link): Account for link_order relocs when
3094 allocating space for relocations. Handle them in link_order loop.
3095 (_bfd_generic_reloc_link_order): New function.
3096 (_bfd_default_link_order): If a reloc_link_order is seen here,
3098 (_bfd_count_link_order_relocs): New function.
3099 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3100 argument from declaration.
3101 (_bfd_generic_reloc_link_order): Declare.
3102 (_bfd_count_link_order_relocs): Declare.
3103 * libbfd.h: Rebuilt.
3104 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3105 call to _bfd_generic_link_add_one_symbol.

3111 call to _bfd_generic_link_add_one_symbol.
3112 (ecoff_bfd_final_link): Account for link_order relocs when
3113 allocating space for relocations. Handle them in link_order loop.
3114 (ecoff_link_write_external): Set the storage class of a defined
3115 linker created symbol based on the section it is in. Correct
3116 bfd_link_hash_weak case to use .sc rather than .st.
3117 (ecoff_reloc_link_order): New function.
3118 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3120 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3125 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3126 bfd_zmalloc. Free a pointer, not a union.
3127 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3129 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3131 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3133 * som.c (bfd_section_from_som_symbol): Only to do the value
3134 comparison for function symbols within executables.
3136 * som.c (bfd_section_from_som_symbol): Renamed from
3137 som_section_from_subspace_index. Pass in a native SOM symbol.
3138 For executables, iterate through the sections to find out
3139 which contains the symbol's address rather than using the
3140 symbol_info field. (symbol_info has a different meaning for
3141 dynamicly linked executables.)
3143 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3146 * som.c (som_begin_writing): Fix braino (one call to align
3147 space/subspace data was done unconditionally rather than
3148 just for executables.)
3150 * som.c (som_begin_writing): Align text in all executables to
3151 make HPUX kernel happy. Fixes strip/objcopy for shared
3154 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3156 * som.c (som_begin_writing): Account for alignment needs of
3157 subspaces too when writing executables. Never request a negative
3158 bss size. Fixes some problems with demand paged executables,
3159 still having problems with pure executables and shared executables.
3161 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3163 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3164 bfd_zalloc for rawptr, because later on we may call free, not
3167 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3168 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3169 * cisco-core.c: New file.
3170 * Makefile.in: Change accordingly.
3171 * configure.in: Recognize cisco_core_vec.
3172 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3173 * targets.c: Add cisco_core_vec.
3174 * bfd-in2.h: Rebuilt.
3176 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3178 * som.h (som_copyable_section_data_struct): New structure
3179 containing all the private section information which needs
3180 to be copied from input section to output section during
3182 (som_section_data_struct): Remove several fields now in
3183 som_copyable_section_data_struct. Make the space and
3184 subspace dictionaries be pointers (to save space when
3185 only reading objects).
3187 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3188 some references changed. Allocate a copyable data stucture if
3189 none exists. Store info into the copyable data structure.
3190 (bfd_som_set_subsection_attributes): Likewise.
3191 (som_is_space, som_is_subspace, som_is_container): New functions.
3192 Use these instead of directly accessing private data.
3193 (som_prep_headers): Allocate space and subspace headers here.
3194 Fill in some fields in the space/subspace headers from the
3196 (som_bfd_copy_private_section_data): Only copy the stuff
3197 that we really need to make objcopy and strip work. Allocate
3198 the copy_data structure for the output bfd before copying.
3200 * som.h (struct som_exec_data): New structure to hold exec
3201 info that must be preserved when running objcopy/strip.
3202 (struct somdata): Add new "exec_data" field and accessor
3203 macro. Add some comments on how the various fields are used.
3204 (som_section_data_struct): Make is_space and is_subspace bitfields.
3205 Delete unused subspace_index. All references now use the
3206 target_index field within the section structure itself.
3208 * som.c (make_unique_section): Delete unused declaration.
3209 (som_bfd_copy_private_bfd_data): New function.
3210 (som_object_setup): Allocate space for and save exec information
3211 that needs to be copied during objcopy/strip.
3212 (som_mkobject): Do not allocate space for a file header here.
3213 It is not used when only reading SOM objects.
3214 (som_prep_headers): Allocate space for and attach a file header
3215 to the output bfd. For executables, use the saved system_id
3216 value rather than trying to guess the right value. Do not abort
3217 wwhen setting file_hdr->entry* for executables.
3218 (som_begin_writing): For executables, set the exec_entry and
3220 (som_copy_private_backend_section_data): Always return a value.
3222 * libhppa.h (PA_PAGESIZE): Define.
3224 * som.c (SOM_ALIGN): Define.
3225 (som_begin_writing): If writing an executable, initialize all
3226 fields in the exec header to zero. Update fields in the exec
3227 header as sizes of loadable subspaces are computed. Carefully
3228 preserve alignments when building executables. Actually write the
3229 exec after all the fields are filled in.
3231 * Better long-filename handling. Reads SOM ABI compliant extended
3232 names, but doesn't quite write compliant extended names yet.
3233 * som.c (som_slurp_extended_name_table): Delete function. The
3234 generic code will handle things correctly.
3235 (som_slurp_armap): Seek to the beginning of the next member.
3236 (normalize): New function.
3237 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3238 name table into account when computing the file offsets in the
3239 SOM dictionary. Make sure to align to an even boundary.
3240 (som_write_armap): Initialize the checksum to zero.
3241 (ar_maxchars): Fix. Opps.
3243 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3245 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3246 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3248 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3250 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3251 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3252 * bfd-in2.h: Regenerated.
3254 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3255 this was also named trad_unix_bfd_copy_private_bfd_data.
3257 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3259 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3260 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3261 returns NULL, it is not an error. It's possible that some of
3262 these checks are not necessary (because the size can never be
3263 zero), but putting in the checks is the conservative thing to do
3264 in light of the fact that some of these malloc calls replaced
3265 unchecked alloca calls, in which a zero argument would work fine.
3267 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3269 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3270 duplicate definition.
3271 (osf_core_bfd_is_local_label): Define.
3273 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3274 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3275 failure indication, it merely means there are no relocs.
3277 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3278 after NAME, since SunOS /bin/cc can't handle it.
3280 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3282 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3283 From sukes@glue.umd.edu (Tasuki Hirata).
3285 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3287 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3288 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3289 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3291 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3293 * som.c (som_prep_for_fixups): Detect section symbols based
3294 on either the lack of private data or the symbol flags. Do not
3295 munge section symbol names anymore -- they no longer confuse GDB.
3296 (som_begin_writing): Leave space for an exec header if writing
3298 (som_slurp_symbol_table): Recognize both forms of section symbol
3299 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3300 section symbols to be the name of the section they represent.
3301 Debugging symbols begin with "L$0\001", not just "L$".
3303 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3305 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3307 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3308 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3309 and bfd_is_local_label.
3311 * targets.c: Add new entries to the bfd_target structure.
3313 * bfd.c (bfd_copy_private_bfd_data): New definition.
3315 * section.c (bfd_copy_private_section_data): New definition.
3317 * syms.c (bfd_is_local_label): New definition.
3319 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3321 * libbfd.c (bfd_generic_is_local_label): New function.
3323 * *-core.c: Provide default definitions for new functions in
3324 the target vector which all point to bfd_false.
3326 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3327 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3328 Default new vectors for copying private backend data to bfd_true.
3329 Default new vector for determining if a symbol is a local label
3330 to bfd_generic_is_local_label.
3332 * som.c (som_bfd_copy_private_section_data): New function.
3333 (som_bfd_is_local_label): New function.
3334 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3336 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3338 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3340 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3342 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3345 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3346 Indent some of them to GNU standards.
3348 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3349 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3350 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3351 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3352 Update copyright years.
3354 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3356 * som.c (som_prep_for_fixups): A relocation involving the section
3357 symbol for the *ABS* section is really a relocation involving
3359 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3360 undefined symbols. Correctly distinguish between debugger symbols
3361 and section symbols.
3363 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3364 for spaces and subspaces.
3366 * som.c (som_bfd_count_ar_symbols): Fix typo.
3368 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3369 HAS_RELOC based on the object's magic number.
3370 (make_unique_section): Delete function. BFD and its users are
3371 prepared to handle multiple sections with the same name.
3372 (setup_sections): Allocate space on the BFD's obstack to hold
3373 section names. Use bfd_make_setion_anyway rather than the
3374 obsolete make_unique_section.
3375 (som_prep_headers): Choose the correct SOM magic number based
3377 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3379 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3381 * elf32-ppc.c: Renamed from elf32-powerpc.c.

3391 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3392 is always located at the start of the data section to allow
3393 recovery of the dynamic info from a stripped executable.
3394 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3397 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3399 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3400 cruft (like the #pragma alloca for AIX).
3401 In addition to that problem, the C alloca calls xmalloc, which
3402 means checking for being out of memory can't work right. The
3403 following changes remove all uses of alloca from BFD.
3404 * hosts/solaris2.h: Remove alloca cruft.
3405 * som.c: Replace alloca with a fixed size auto array.

3410 * linker.c: Replace alloca with obstack_alloc.
3411 * libbfd.h: Rebuilt.
3413 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3415 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3418 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3420 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3421 Elf*_Off typedefs by their expansion, the typedefs have been
3422 removed from include/elf/internal.h.
3423 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3424 SHT_PROGBITS section.
3426 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3428 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3432 * configure.host: Recognize i[34]86-sequent-*.
3434 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3435 return from bfd_seek indicates an error.
3436 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3437 TRAD_CORE_STACK_OFFSET.
3438 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3439 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3441 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3443 * som.[ch]: Do not include libhppa.h in som.c, instead include
3446 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3447 include it in elf32-hppa.h.
3449 * som.c (log2): Return -1 on error rather than aborting.
3450 (setup_sections): Bubble up an error from log2.
3452 * Changes to make HP C compiler happy in both traditional
3454 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3456 (bfd_som_set_section_attributes): Use unsigned int rather than
3457 unsigned char to avoid GNU-C extensions.
3458 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3459 or failure rather than aborting on failure.
3461 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3463 (bfd_som_attach_aux_hdr): Add prototype.
3464 (hppa_som-gen_reloc_type): Likewise.
3466 * elf32-hppa.c: Add a couple casts to make HP compiler happy.

3753 (b_out_relax_section): If a section contains no relocations, don't
3754 bother processing them.
3755 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4458 The sparc (and possibly other?) NLM format requires a different
4459 way to write exports, so add a write_export field to the backend
4460 data (and set it to NULL for everything but the sparc).
