3873 in asymbol udata field.
3875 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3877 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3878 reloc, used in embedded PIC code.

3886 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3887 add_symbls entry point.
3889 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3890 counting relocs. Set SEC_RELOC flag for any section which has

3895 * linker.c (_bfd_generic_link_add_symbols): Just call
3896 generic_link_add_symbols.
3897 (_bfd_generic_link_add_symbols_collect): New function, like
3898 _bfd_generic_link_add_symbols but also collect constructors and
3899 destructors by name as collect2 does.
3900 (generic_link_add_symbols): New function, like old
3901 _bfd_generic_link_add_symbols but with collect argument.
3902 (generic_link_add_object_symbols): Take collect argument.

3914 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
3915 for first character in an extended name.
3916 (_bfd_write_archive_contents): If ar_padchar == '/', then use
3917 "//" as the name of the special archive member holding the
3918 extended name table.
3920 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3922 Support for link_order types which generate relocs in order to
3923 support -Ur in the linker.
3924 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3925 from call to _bfd_generic_link_add_one_symbol.
3926 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3927 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3928 instead of bitsize to add_to_set call back.
3929 (_bfd_generic_final_link): Account for link_order relocs when
3930 allocating space for relocations. Handle them in link_order loop.
3931 (_bfd_generic_reloc_link_order): New function.
3932 (_bfd_default_link_order): If a reloc_link_order is seen here,
3934 (_bfd_count_link_order_relocs): New function.
3935 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3936 argument from declaration.
3937 (_bfd_generic_reloc_link_order): Declare.
3938 (_bfd_count_link_order_relocs): Declare.

3940 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3941 call to _bfd_generic_link_add_one_symbol.
3942 (NAME(aout,final_link)): Account for link_order relocs when

3947 call to _bfd_generic_link_add_one_symbol.
3948 (ecoff_bfd_final_link): Account for link_order relocs when
3949 allocating space for relocations. Handle them in link_order loop.
3950 (ecoff_link_write_external): Set the storage class of a defined
3951 linker created symbol based on the section it is in. Correct
3952 bfd_link_hash_weak case to use .sc rather than .st.
3953 (ecoff_reloc_link_order): New function.
3954 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3956 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3965 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3967 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3969 * som.c (bfd_section_from_som_symbol): Only to do the value
3970 comparison for function symbols within executables.
3972 * som.c (bfd_section_from_som_symbol): Renamed from
3973 som_section_from_subspace_index. Pass in a native SOM symbol.
3974 For executables, iterate through the sections to find out
3975 which contains the symbol's address rather than using the
3976 symbol_info field. (symbol_info has a different meaning for
3977 dynamicly linked executables.)
3979 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3982 * som.c (som_begin_writing): Fix braino (one call to align
3983 space/subspace data was done unconditionally rather than
3984 just for executables.)
3986 * som.c (som_begin_writing): Align text in all executables to
3987 make HPUX kernel happy. Fixes strip/objcopy for shared
3990 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3992 * som.c (som_begin_writing): Account for alignment needs of
3993 subspaces too when writing executables. Never request a negative
3994 bss size. Fixes some problems with demand paged executables,
3995 still having problems with pure executables and shared executables.
3997 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3999 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4000 bfd_zalloc for rawptr, because later on we may call free, not
4003 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4004 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4005 * cisco-core.c: New file.
4006 * Makefile.in: Change accordingly.
4007 * configure.in: Recognize cisco_core_vec.
4008 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4009 * targets.c: Add cisco_core_vec.
4010 * bfd-in2.h: Rebuilt.
4012 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4014 * som.h (som_copyable_section_data_struct): New structure
4015 containing all the private section information which needs
4016 to be copied from input section to output section during
4018 (som_section_data_struct): Remove several fields now in
4019 som_copyable_section_data_struct. Make the space and
4020 subspace dictionaries be pointers (to save space when
4021 only reading objects).
4023 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4024 some references changed. Allocate a copyable data stucture if
4025 none exists. Store info into the copyable data structure.
4026 (bfd_som_set_subsection_attributes): Likewise.
4027 (som_is_space, som_is_subspace, som_is_container): New functions.
4028 Use these instead of directly accessing private data.
4029 (som_prep_headers): Allocate space and subspace headers here.
4030 Fill in some fields in the space/subspace headers from the
4032 (som_bfd_copy_private_section_data): Only copy the stuff
4033 that we really need to make objcopy and strip work. Allocate
4034 the copy_data structure for the output bfd before copying.
4036 * som.h (struct som_exec_data): New structure to hold exec
4037 info that must be preserved when running objcopy/strip.
4038 (struct somdata): Add new "exec_data" field and accessor
4039 macro. Add some comments on how the various fields are used.
4040 (som_section_data_struct): Make is_space and is_subspace bitfields.
4041 Delete unused subspace_index. All references now use the
4042 target_index field within the section structure itself.
4044 * som.c (make_unique_section): Delete unused declaration.
4045 (som_bfd_copy_private_bfd_data): New function.
4046 (som_object_setup): Allocate space for and save exec information
4047 that needs to be copied during objcopy/strip.
4048 (som_mkobject): Do not allocate space for a file header here.
4049 It is not used when only reading SOM objects.
4050 (som_prep_headers): Allocate space for and attach a file header
4051 to the output bfd. For executables, use the saved system_id
4052 value rather than trying to guess the right value. Do not abort
4053 wwhen setting file_hdr->entry* for executables.
4054 (som_begin_writing): For executables, set the exec_entry and
4056 (som_copy_private_backend_section_data): Always return a value.
4058 * libhppa.h (PA_PAGESIZE): Define.
4060 * som.c (SOM_ALIGN): Define.
4061 (som_begin_writing): If writing an executable, initialize all
4062 fields in the exec header to zero. Update fields in the exec
4063 header as sizes of loadable subspaces are computed. Carefully
4064 preserve alignments when building executables. Actually write the
4065 exec after all the fields are filled in.
4067 * Better long-filename handling. Reads SOM ABI compliant extended
4068 names, but doesn't quite write compliant extended names yet.
4069 * som.c (som_slurp_extended_name_table): Delete function. The
4070 generic code will handle things correctly.
4071 (som_slurp_armap): Seek to the beginning of the next member.
4072 (normalize): New function.
4073 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4074 name table into account when computing the file offsets in the
4075 SOM dictionary. Make sure to align to an even boundary.
4076 (som_write_armap): Initialize the checksum to zero.
4077 (ar_maxchars): Fix. Opps.
4079 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4081 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4082 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4084 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4086 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4087 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4088 * bfd-in2.h: Regenerated.
4090 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4091 this was also named trad_unix_bfd_copy_private_bfd_data.
4093 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4095 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4096 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4097 returns NULL, it is not an error. It's possible that some of
4098 these checks are not necessary (because the size can never be
4099 zero), but putting in the checks is the conservative thing to do
4100 in light of the fact that some of these malloc calls replaced
4101 unchecked alloca calls, in which a zero argument would work fine.
4103 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4105 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4106 duplicate definition.
4107 (osf_core_bfd_is_local_label): Define.
4109 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4110 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4111 failure indication, it merely means there are no relocs.
4113 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4114 after NAME, since SunOS /bin/cc can't handle it.
4116 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4118 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4119 From sukes@glue.umd.edu (Tasuki Hirata).
4121 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4123 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4124 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4125 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4127 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4129 * som.c (som_prep_for_fixups): Detect section symbols based
4130 on either the lack of private data or the symbol flags. Do not
4131 munge section symbol names anymore -- they no longer confuse GDB.
4132 (som_begin_writing): Leave space for an exec header if writing
4134 (som_slurp_symbol_table): Recognize both forms of section symbol
4135 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4136 section symbols to be the name of the section they represent.
4137 Debugging symbols begin with "L$0\001", not just "L$".
4139 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4141 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4143 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4144 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4145 and bfd_is_local_label.
4147 * targets.c: Add new entries to the bfd_target structure.
4149 * bfd.c (bfd_copy_private_bfd_data): New definition.
4151 * section.c (bfd_copy_private_section_data): New definition.
4153 * syms.c (bfd_is_local_label): New definition.

4157 * libbfd.c (bfd_generic_is_local_label): New function.
4159 * *-core.c: Provide default definitions for new functions in
4160 the target vector which all point to bfd_false.
4162 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4163 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4164 Default new vectors for copying private backend data to bfd_true.
4165 Default new vector for determining if a symbol is a local label
4166 to bfd_generic_is_local_label.
4168 * som.c (som_bfd_copy_private_section_data): New function.
4169 (som_bfd_is_local_label): New function.
4170 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4172 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4174 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4176 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4178 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4181 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4182 Indent some of them to GNU standards.
4184 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4185 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4186 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4187 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4188 Update copyright years.
4190 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4192 * som.c (som_prep_for_fixups): A relocation involving the section
4193 symbol for the *ABS* section is really a relocation involving
4195 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4196 undefined symbols. Correctly distinguish between debugger symbols
4197 and section symbols.
4199 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4200 for spaces and subspaces.
4202 * som.c (som_bfd_count_ar_symbols): Fix typo.
4204 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4205 HAS_RELOC based on the object's magic number.
4206 (make_unique_section): Delete function. BFD and its users are
4207 prepared to handle multiple sections with the same name.
4208 (setup_sections): Allocate space on the BFD's obstack to hold
4209 section names. Use bfd_make_setion_anyway rather than the
4210 obsolete make_unique_section.
4211 (som_prep_headers): Choose the correct SOM magic number based
4213 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4215 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4217 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4227 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4228 is always located at the start of the data section to allow
4229 recovery of the dynamic info from a stripped executable.
4230 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4233 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4235 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4236 cruft (like the #pragma alloca for AIX).
4237 In addition to that problem, the C alloca calls xmalloc, which
4238 means checking for being out of memory can't work right. The
4239 following changes remove all uses of alloca from BFD.
4240 * hosts/solaris2.h: Remove alloca cruft.
4241 * som.c: Replace alloca with a fixed size auto array.

4246 * linker.c: Replace alloca with obstack_alloc.
4247 * libbfd.h: Rebuilt.
4249 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4251 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4254 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4256 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4257 Elf*_Off typedefs by their expansion, the typedefs have been
4258 removed from include/elf/internal.h.
4259 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4260 SHT_PROGBITS section.
4262 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4264 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4268 * configure.host: Recognize i[34]86-sequent-*.
4270 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4271 return from bfd_seek indicates an error.
4272 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4273 TRAD_CORE_STACK_OFFSET.
4274 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4275 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4277 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4279 * som.[ch]: Do not include libhppa.h in som.c, instead include
4282 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4283 include it in elf32-hppa.h.
4285 * som.c (log2): Return -1 on error rather than aborting.
4286 (setup_sections): Bubble up an error from log2.
4288 * Changes to make HP C compiler happy in both traditional
4290 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4292 (bfd_som_set_section_attributes): Use unsigned int rather than
4293 unsigned char to avoid GNU-C extensions.
4294 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4295 or failure rather than aborting on failure.
4297 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4299 (bfd_som_attach_aux_hdr): Add prototype.
4300 (hppa_som-gen_reloc_type): Likewise.
4302 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4303 (hppa_look_for_stubs_in_section): Do not return false on failure
4304 until rest of code is ready to handle it. Abort for now.
4306 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4308 * bfd-in2.h: Rebuilt.
4310 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
4312 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

4589 (b_out_relax_section): If a section contains no relocations, don't
4590 bother processing them.
4591 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5294 The sparc (and possibly other?) NLM format requires a different
5295 way to write exports, so add a write_export field to the backend
5296 data (and set it to NULL for everything but the sparc).
