3088 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3090 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3091 reloc, used in embedded PIC code.
3092 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

3111 _bfd_generic_link_add_symbols but also collect constructors and
3112 destructors by name as collect2 does.

3131 extended name table.
3133 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3135 Support for link_order types which generate relocs in order to
3136 support -Ur in the linker.
3137 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3138 from call to _bfd_generic_link_add_one_symbol.
3139 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3140 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3141 instead of bitsize to add_to_set call back.
3142 (_bfd_generic_final_link): Account for link_order relocs when
3143 allocating space for relocations. Handle them in link_order loop.
3144 (_bfd_generic_reloc_link_order): New function.

3162 allocating space for relocations. Handle them in link_order loop.
3163 (ecoff_link_write_external): Set the storage class of a defined
3164 linker created symbol based on the section it is in. Correct
3165 bfd_link_hash_weak case to use .sc rather than .st.

3178 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3180 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3182 * som.c (bfd_section_from_som_symbol): Only to do the value
3183 comparison for function symbols within executables.
3185 * som.c (bfd_section_from_som_symbol): Renamed from
3186 som_section_from_subspace_index. Pass in a native SOM symbol.
3187 For executables, iterate through the sections to find out
3188 which contains the symbol's address rather than using the
3189 symbol_info field. (symbol_info has a different meaning for
3190 dynamicly linked executables.)
3192 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3195 * som.c (som_begin_writing): Fix braino (one call to align
3196 space/subspace data was done unconditionally rather than
3197 just for executables.)
3199 * som.c (som_begin_writing): Align text in all executables to
3200 make HPUX kernel happy. Fixes strip/objcopy for shared
3203 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3205 * som.c (som_begin_writing): Account for alignment needs of
3206 subspaces too when writing executables. Never request a negative
3207 bss size. Fixes some problems with demand paged executables,
3208 still having problems with pure executables and shared executables.
3210 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3212 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3213 bfd_zalloc for rawptr, because later on we may call free, not
3216 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3217 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3218 * cisco-core.c: New file.
3219 * Makefile.in: Change accordingly.
3220 * configure.in: Recognize cisco_core_vec.
3221 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3222 * targets.c: Add cisco_core_vec.
3223 * bfd-in2.h: Rebuilt.
3225 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3227 * som.h (som_copyable_section_data_struct): New structure
3228 containing all the private section information which needs
3229 to be copied from input section to output section during
3231 (som_section_data_struct): Remove several fields now in
3232 som_copyable_section_data_struct. Make the space and
3233 subspace dictionaries be pointers (to save space when
3234 only reading objects).
3236 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3237 some references changed. Allocate a copyable data stucture if
3238 none exists. Store info into the copyable data structure.
3239 (bfd_som_set_subsection_attributes): Likewise.
3240 (som_is_space, som_is_subspace, som_is_container): New functions.
3241 Use these instead of directly accessing private data.
3242 (som_prep_headers): Allocate space and subspace headers here.
3243 Fill in some fields in the space/subspace headers from the
3245 (som_bfd_copy_private_section_data): Only copy the stuff
3246 that we really need to make objcopy and strip work. Allocate
3247 the copy_data structure for the output bfd before copying.
3249 * som.h (struct som_exec_data): New structure to hold exec
3250 info that must be preserved when running objcopy/strip.
3251 (struct somdata): Add new "exec_data" field and accessor
3252 macro. Add some comments on how the various fields are used.
3253 (som_section_data_struct): Make is_space and is_subspace bitfields.
3254 Delete unused subspace_index. All references now use the
3255 target_index field within the section structure itself.
3257 * som.c (make_unique_section): Delete unused declaration.
3258 (som_bfd_copy_private_bfd_data): New function.
3259 (som_object_setup): Allocate space for and save exec information
3260 that needs to be copied during objcopy/strip.
3261 (som_mkobject): Do not allocate space for a file header here.
3262 It is not used when only reading SOM objects.
3263 (som_prep_headers): Allocate space for and attach a file header
3264 to the output bfd. For executables, use the saved system_id
3265 value rather than trying to guess the right value. Do not abort
3266 wwhen setting file_hdr->entry* for executables.
3267 (som_begin_writing): For executables, set the exec_entry and
3269 (som_copy_private_backend_section_data): Always return a value.
3271 * libhppa.h (PA_PAGESIZE): Define.
3273 * som.c (SOM_ALIGN): Define.
3274 (som_begin_writing): If writing an executable, initialize all
3275 fields in the exec header to zero. Update fields in the exec
3276 header as sizes of loadable subspaces are computed. Carefully
3277 preserve alignments when building executables. Actually write the
3278 exec after all the fields are filled in.
3280 * Better long-filename handling. Reads SOM ABI compliant extended
3281 names, but doesn't quite write compliant extended names yet.
3282 * som.c (som_slurp_extended_name_table): Delete function. The
3283 generic code will handle things correctly.
3284 (som_slurp_armap): Seek to the beginning of the next member.
3285 (normalize): New function.
3286 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3287 name table into account when computing the file offsets in the
3288 SOM dictionary. Make sure to align to an even boundary.
3289 (som_write_armap): Initialize the checksum to zero.
3290 (ar_maxchars): Fix. Opps.
3292 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3294 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3295 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3297 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3299 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3300 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3301 * bfd-in2.h: Regenerated.
3303 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3304 this was also named trad_unix_bfd_copy_private_bfd_data.
3306 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3308 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3309 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3310 returns NULL, it is not an error. It's possible that some of
3311 these checks are not necessary (because the size can never be
3312 zero), but putting in the checks is the conservative thing to do
3313 in light of the fact that some of these malloc calls replaced
3314 unchecked alloca calls, in which a zero argument would work fine.
3316 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3318 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3319 duplicate definition.
3320 (osf_core_bfd_is_local_label): Define.
3322 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3323 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3324 failure indication, it merely means there are no relocs.
3326 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3327 after NAME, since SunOS /bin/cc can't handle it.
3329 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3331 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3332 From sukes@glue.umd.edu (Tasuki Hirata).
3334 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3336 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3337 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3338 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3340 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3342 * som.c (som_prep_for_fixups): Detect section symbols based
3343 on either the lack of private data or the symbol flags. Do not
3344 munge section symbol names anymore -- they no longer confuse GDB.
3345 (som_begin_writing): Leave space for an exec header if writing
3347 (som_slurp_symbol_table): Recognize both forms of section symbol
3348 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3349 section symbols to be the name of the section they represent.
3350 Debugging symbols begin with "L$0\001", not just "L$".
3352 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3354 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3356 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3357 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3358 and bfd_is_local_label.
3360 * targets.c: Add new entries to the bfd_target structure.
3362 * bfd.c (bfd_copy_private_bfd_data): New definition.
3364 * section.c (bfd_copy_private_section_data): New definition.
3366 * syms.c (bfd_is_local_label): New definition.
3368 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3370 * libbfd.c (bfd_generic_is_local_label): New function.
3372 * *-core.c: Provide default definitions for new functions in
3373 the target vector which all point to bfd_false.
3375 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3376 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3377 Default new vectors for copying private backend data to bfd_true.
3378 Default new vector for determining if a symbol is a local label
3379 to bfd_generic_is_local_label.
3381 * som.c (som_bfd_copy_private_section_data): New function.
3382 (som_bfd_is_local_label): New function.
3383 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3385 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3387 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3389 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3391 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3394 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3395 Indent some of them to GNU standards.
3397 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3398 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3399 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3400 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3401 Update copyright years.
3403 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3405 * som.c (som_prep_for_fixups): A relocation involving the section
3406 symbol for the *ABS* section is really a relocation involving
3408 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3409 undefined symbols. Correctly distinguish between debugger symbols
3410 and section symbols.
3412 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3413 for spaces and subspaces.
3415 * som.c (som_bfd_count_ar_symbols): Fix typo.
3417 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3418 HAS_RELOC based on the object's magic number.
3419 (make_unique_section): Delete function. BFD and its users are
3420 prepared to handle multiple sections with the same name.
3421 (setup_sections): Allocate space on the BFD's obstack to hold
3422 section names. Use bfd_make_setion_anyway rather than the
3423 obsolete make_unique_section.
3424 (som_prep_headers): Choose the correct SOM magic number based
3426 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3428 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3430 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3431 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3432 * Makefile.in, configure.in: Corresponding changes.

3436 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3438 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3440 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3441 is always located at the start of the data section to allow
3442 recovery of the dynamic info from a stripped executable.
3443 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3446 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3448 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3449 cruft (like the #pragma alloca for AIX).
3450 In addition to that problem, the C alloca calls xmalloc, which
3451 means checking for being out of memory can't work right. The
3452 following changes remove all uses of alloca from BFD.
3453 * hosts/solaris2.h: Remove alloca cruft.
3454 * som.c: Replace alloca with a fixed size auto array.
3455 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3456 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3457 sunos.c: Replace alloca with malloc and appropriate error checking and

3803 bother processing them.

4507 The sparc (and possibly other?) NLM format requires a different
4508 way to write exports, so add a write_export field to the backend
4509 data (and set it to NULL for everything but the sparc).

4675 sym_filepos as well.
4676 (ecoff_get_extr): Use ifdmap instead of ifdbase.

4753 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
4754 different, so there is no point to providing a generic one.
4755 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
4756 in the backend accessor macros; that should no longer be possible.
