3093 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3095 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3096 reloc, used in embedded PIC code.
3097 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

3116 _bfd_generic_link_add_symbols but also collect constructors and
3117 destructors by name as collect2 does.
3118 (generic_link_add_symbols): New function, like old
3119 _bfd_generic_link_add_symbols but with collect argument.

3136 extended name table.
3138 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3140 Support for link_order types which generate relocs in order to
3141 support -Ur in the linker.
3142 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3143 from call to _bfd_generic_link_add_one_symbol.
3144 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3145 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3146 instead of bitsize to add_to_set call back.
3147 (_bfd_generic_final_link): Account for link_order relocs when
3148 allocating space for relocations. Handle them in link_order loop.
3149 (_bfd_generic_reloc_link_order): New function.

3167 allocating space for relocations. Handle them in link_order loop.
3168 (ecoff_link_write_external): Set the storage class of a defined
3169 linker created symbol based on the section it is in. Correct
3170 bfd_link_hash_weak case to use .sc rather than .st.

3183 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3185 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3187 * som.c (bfd_section_from_som_symbol): Only to do the value
3188 comparison for function symbols within executables.
3190 * som.c (bfd_section_from_som_symbol): Renamed from
3191 som_section_from_subspace_index. Pass in a native SOM symbol.
3192 For executables, iterate through the sections to find out
3193 which contains the symbol's address rather than using the
3194 symbol_info field. (symbol_info has a different meaning for
3195 dynamicly linked executables.)
3197 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3200 * som.c (som_begin_writing): Fix braino (one call to align
3201 space/subspace data was done unconditionally rather than
3202 just for executables.)
3204 * som.c (som_begin_writing): Align text in all executables to
3205 make HPUX kernel happy. Fixes strip/objcopy for shared
3208 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3210 * som.c (som_begin_writing): Account for alignment needs of
3211 subspaces too when writing executables. Never request a negative
3212 bss size. Fixes some problems with demand paged executables,
3213 still having problems with pure executables and shared executables.
3215 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3217 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3218 bfd_zalloc for rawptr, because later on we may call free, not
3221 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3222 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3223 * cisco-core.c: New file.
3224 * Makefile.in: Change accordingly.
3225 * configure.in: Recognize cisco_core_vec.
3226 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3227 * targets.c: Add cisco_core_vec.
3228 * bfd-in2.h: Rebuilt.
3230 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3232 * som.h (som_copyable_section_data_struct): New structure
3233 containing all the private section information which needs
3234 to be copied from input section to output section during
3236 (som_section_data_struct): Remove several fields now in
3237 som_copyable_section_data_struct. Make the space and
3238 subspace dictionaries be pointers (to save space when
3239 only reading objects).
3241 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3242 some references changed. Allocate a copyable data stucture if
3243 none exists. Store info into the copyable data structure.
3244 (bfd_som_set_subsection_attributes): Likewise.
3245 (som_is_space, som_is_subspace, som_is_container): New functions.
3246 Use these instead of directly accessing private data.
3247 (som_prep_headers): Allocate space and subspace headers here.
3248 Fill in some fields in the space/subspace headers from the
3250 (som_bfd_copy_private_section_data): Only copy the stuff
3251 that we really need to make objcopy and strip work. Allocate
3252 the copy_data structure for the output bfd before copying.
3254 * som.h (struct som_exec_data): New structure to hold exec
3255 info that must be preserved when running objcopy/strip.
3256 (struct somdata): Add new "exec_data" field and accessor
3257 macro. Add some comments on how the various fields are used.
3258 (som_section_data_struct): Make is_space and is_subspace bitfields.
3259 Delete unused subspace_index. All references now use the
3260 target_index field within the section structure itself.
3262 * som.c (make_unique_section): Delete unused declaration.
3263 (som_bfd_copy_private_bfd_data): New function.
3264 (som_object_setup): Allocate space for and save exec information
3265 that needs to be copied during objcopy/strip.
3266 (som_mkobject): Do not allocate space for a file header here.
3267 It is not used when only reading SOM objects.
3268 (som_prep_headers): Allocate space for and attach a file header
3269 to the output bfd. For executables, use the saved system_id
3270 value rather than trying to guess the right value. Do not abort
3271 wwhen setting file_hdr->entry* for executables.
3272 (som_begin_writing): For executables, set the exec_entry and
3274 (som_copy_private_backend_section_data): Always return a value.
3276 * libhppa.h (PA_PAGESIZE): Define.
3278 * som.c (SOM_ALIGN): Define.
3279 (som_begin_writing): If writing an executable, initialize all
3280 fields in the exec header to zero. Update fields in the exec
3281 header as sizes of loadable subspaces are computed. Carefully
3282 preserve alignments when building executables. Actually write the
3283 exec after all the fields are filled in.
3285 * Better long-filename handling. Reads SOM ABI compliant extended
3286 names, but doesn't quite write compliant extended names yet.
3287 * som.c (som_slurp_extended_name_table): Delete function. The
3288 generic code will handle things correctly.
3289 (som_slurp_armap): Seek to the beginning of the next member.
3290 (normalize): New function.
3291 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3292 name table into account when computing the file offsets in the
3293 SOM dictionary. Make sure to align to an even boundary.
3294 (som_write_armap): Initialize the checksum to zero.
3295 (ar_maxchars): Fix. Opps.
3297 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3299 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3300 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3302 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3304 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3305 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3306 * bfd-in2.h: Regenerated.
3308 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3309 this was also named trad_unix_bfd_copy_private_bfd_data.
3311 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3313 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3314 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3315 returns NULL, it is not an error. It's possible that some of
3316 these checks are not necessary (because the size can never be
3317 zero), but putting in the checks is the conservative thing to do
3318 in light of the fact that some of these malloc calls replaced
3319 unchecked alloca calls, in which a zero argument would work fine.
3321 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3323 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3324 duplicate definition.
3325 (osf_core_bfd_is_local_label): Define.
3327 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3328 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3329 failure indication, it merely means there are no relocs.
3331 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3332 after NAME, since SunOS /bin/cc can't handle it.
3334 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3336 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3337 From sukes@glue.umd.edu (Tasuki Hirata).
3339 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3341 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3342 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3343 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3345 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3347 * som.c (som_prep_for_fixups): Detect section symbols based
3348 on either the lack of private data or the symbol flags. Do not
3349 munge section symbol names anymore -- they no longer confuse GDB.
3350 (som_begin_writing): Leave space for an exec header if writing
3352 (som_slurp_symbol_table): Recognize both forms of section symbol
3353 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3354 section symbols to be the name of the section they represent.
3355 Debugging symbols begin with "L$0\001", not just "L$".
3357 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3359 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3361 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3362 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3363 and bfd_is_local_label.
3365 * targets.c: Add new entries to the bfd_target structure.
3367 * bfd.c (bfd_copy_private_bfd_data): New definition.
3369 * section.c (bfd_copy_private_section_data): New definition.
3371 * syms.c (bfd_is_local_label): New definition.
3373 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3375 * libbfd.c (bfd_generic_is_local_label): New function.
3377 * *-core.c: Provide default definitions for new functions in
3378 the target vector which all point to bfd_false.
3380 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3381 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3382 Default new vectors for copying private backend data to bfd_true.
3383 Default new vector for determining if a symbol is a local label
3384 to bfd_generic_is_local_label.
3386 * som.c (som_bfd_copy_private_section_data): New function.
3387 (som_bfd_is_local_label): New function.
3388 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3390 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3392 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3394 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3396 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3399 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3400 Indent some of them to GNU standards.
3402 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3403 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3404 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3405 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3406 Update copyright years.
3408 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3410 * som.c (som_prep_for_fixups): A relocation involving the section
3411 symbol for the *ABS* section is really a relocation involving
3413 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3414 undefined symbols. Correctly distinguish between debugger symbols
3415 and section symbols.
3417 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3418 for spaces and subspaces.
3420 * som.c (som_bfd_count_ar_symbols): Fix typo.
3422 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3423 HAS_RELOC based on the object's magic number.
3424 (make_unique_section): Delete function. BFD and its users are
3425 prepared to handle multiple sections with the same name.
3426 (setup_sections): Allocate space on the BFD's obstack to hold
3427 section names. Use bfd_make_setion_anyway rather than the
3428 obsolete make_unique_section.
3429 (som_prep_headers): Choose the correct SOM magic number based
3431 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3433 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3435 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3436 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3437 * Makefile.in, configure.in: Corresponding changes.

3441 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3443 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3445 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3446 is always located at the start of the data section to allow
3447 recovery of the dynamic info from a stripped executable.
3448 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3451 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3453 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3454 cruft (like the #pragma alloca for AIX).
3455 In addition to that problem, the C alloca calls xmalloc, which
3456 means checking for being out of memory can't work right. The
3457 following changes remove all uses of alloca from BFD.
3458 * hosts/solaris2.h: Remove alloca cruft.

3808 bother processing them.
3809 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4512 The sparc (and possibly other?) NLM format requires a different
4513 way to write exports, so add a write_export field to the backend
4514 data (and set it to NULL for everything but the sparc).

4753 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

4758 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
4759 different, so there is no point to providing a generic one.
4760 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
4761 in the backend accessor macros; that should no longer be possible.
