3901 in asymbol udata field.
3903 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3905 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3906 reloc, used in embedded PIC code.
3907 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

3914 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3915 add_symbls entry point.
3917 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3918 counting relocs. Set SEC_RELOC flag for any section which has

3924 generic_link_add_symbols.
3925 (_bfd_generic_link_add_symbols_collect): New function, like
3926 _bfd_generic_link_add_symbols but also collect constructors and
3927 destructors by name as collect2 does.
3928 (generic_link_add_symbols): New function, like old
3929 _bfd_generic_link_add_symbols but with collect argument.
3930 (generic_link_add_object_symbols): Take collect argument.

3942 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
3943 for first character in an extended name.
3944 (_bfd_write_archive_contents): If ar_padchar == '/', then use
3945 "//" as the name of the special archive member holding the
3946 extended name table.
3948 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3950 Support for link_order types which generate relocs in order to
3951 support -Ur in the linker.
3952 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3953 from call to _bfd_generic_link_add_one_symbol.
3954 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3955 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3956 instead of bitsize to add_to_set call back.
3957 (_bfd_generic_final_link): Account for link_order relocs when
3958 allocating space for relocations. Handle them in link_order loop.
3959 (_bfd_generic_reloc_link_order): New function.

3962 (_bfd_count_link_order_relocs): New function.
3963 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3964 argument from declaration.
3965 (_bfd_generic_reloc_link_order): Declare.
3966 (_bfd_count_link_order_relocs): Declare.

3977 allocating space for relocations. Handle them in link_order loop.
3978 (ecoff_link_write_external): Set the storage class of a defined
3979 linker created symbol based on the section it is in. Correct
3980 bfd_link_hash_weak case to use .sc rather than .st.
3981 (ecoff_reloc_link_order): New function.
3982 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3984 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3993 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3995 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3997 * som.c (bfd_section_from_som_symbol): Only to do the value
3998 comparison for function symbols within executables.
4000 * som.c (bfd_section_from_som_symbol): Renamed from
4001 som_section_from_subspace_index. Pass in a native SOM symbol.
4002 For executables, iterate through the sections to find out
4003 which contains the symbol's address rather than using the
4004 symbol_info field. (symbol_info has a different meaning for
4005 dynamicly linked executables.)
4007 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4010 * som.c (som_begin_writing): Fix braino (one call to align
4011 space/subspace data was done unconditionally rather than
4012 just for executables.)
4014 * som.c (som_begin_writing): Align text in all executables to
4015 make HPUX kernel happy. Fixes strip/objcopy for shared
4018 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4020 * som.c (som_begin_writing): Account for alignment needs of
4021 subspaces too when writing executables. Never request a negative
4022 bss size. Fixes some problems with demand paged executables,
4023 still having problems with pure executables and shared executables.
4025 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4027 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4028 bfd_zalloc for rawptr, because later on we may call free, not
4031 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4032 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4033 * cisco-core.c: New file.
4034 * Makefile.in: Change accordingly.
4035 * configure.in: Recognize cisco_core_vec.
4036 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4037 * targets.c: Add cisco_core_vec.
4038 * bfd-in2.h: Rebuilt.
4040 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4042 * som.h (som_copyable_section_data_struct): New structure
4043 containing all the private section information which needs
4044 to be copied from input section to output section during
4046 (som_section_data_struct): Remove several fields now in
4047 som_copyable_section_data_struct. Make the space and
4048 subspace dictionaries be pointers (to save space when
4049 only reading objects).
4051 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4052 some references changed. Allocate a copyable data stucture if
4053 none exists. Store info into the copyable data structure.
4054 (bfd_som_set_subsection_attributes): Likewise.
4055 (som_is_space, som_is_subspace, som_is_container): New functions.
4056 Use these instead of directly accessing private data.
4057 (som_prep_headers): Allocate space and subspace headers here.
4058 Fill in some fields in the space/subspace headers from the
4060 (som_bfd_copy_private_section_data): Only copy the stuff
4061 that we really need to make objcopy and strip work. Allocate
4062 the copy_data structure for the output bfd before copying.
4064 * som.h (struct som_exec_data): New structure to hold exec
4065 info that must be preserved when running objcopy/strip.
4066 (struct somdata): Add new "exec_data" field and accessor
4067 macro. Add some comments on how the various fields are used.
4068 (som_section_data_struct): Make is_space and is_subspace bitfields.
4069 Delete unused subspace_index. All references now use the
4070 target_index field within the section structure itself.
4072 * som.c (make_unique_section): Delete unused declaration.
4073 (som_bfd_copy_private_bfd_data): New function.
4074 (som_object_setup): Allocate space for and save exec information
4075 that needs to be copied during objcopy/strip.
4076 (som_mkobject): Do not allocate space for a file header here.
4077 It is not used when only reading SOM objects.
4078 (som_prep_headers): Allocate space for and attach a file header
4079 to the output bfd. For executables, use the saved system_id
4080 value rather than trying to guess the right value. Do not abort
4081 wwhen setting file_hdr->entry* for executables.
4082 (som_begin_writing): For executables, set the exec_entry and
4084 (som_copy_private_backend_section_data): Always return a value.
4086 * libhppa.h (PA_PAGESIZE): Define.
4088 * som.c (SOM_ALIGN): Define.
4089 (som_begin_writing): If writing an executable, initialize all
4090 fields in the exec header to zero. Update fields in the exec
4091 header as sizes of loadable subspaces are computed. Carefully
4092 preserve alignments when building executables. Actually write the
4093 exec after all the fields are filled in.
4095 * Better long-filename handling. Reads SOM ABI compliant extended
4096 names, but doesn't quite write compliant extended names yet.
4097 * som.c (som_slurp_extended_name_table): Delete function. The
4098 generic code will handle things correctly.
4099 (som_slurp_armap): Seek to the beginning of the next member.
4100 (normalize): New function.
4101 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4102 name table into account when computing the file offsets in the
4103 SOM dictionary. Make sure to align to an even boundary.
4104 (som_write_armap): Initialize the checksum to zero.
4105 (ar_maxchars): Fix. Opps.
4107 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4109 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4110 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4112 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4114 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4115 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4116 * bfd-in2.h: Regenerated.
4118 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4119 this was also named trad_unix_bfd_copy_private_bfd_data.
4121 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4123 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4124 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4125 returns NULL, it is not an error. It's possible that some of
4126 these checks are not necessary (because the size can never be
4127 zero), but putting in the checks is the conservative thing to do
4128 in light of the fact that some of these malloc calls replaced
4129 unchecked alloca calls, in which a zero argument would work fine.
4131 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4133 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4134 duplicate definition.
4135 (osf_core_bfd_is_local_label): Define.
4137 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4138 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4139 failure indication, it merely means there are no relocs.
4141 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4142 after NAME, since SunOS /bin/cc can't handle it.
4144 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4146 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4147 From sukes@glue.umd.edu (Tasuki Hirata).
4149 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4151 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4152 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4153 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4155 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4157 * som.c (som_prep_for_fixups): Detect section symbols based
4158 on either the lack of private data or the symbol flags. Do not
4159 munge section symbol names anymore -- they no longer confuse GDB.
4160 (som_begin_writing): Leave space for an exec header if writing
4162 (som_slurp_symbol_table): Recognize both forms of section symbol
4163 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4164 section symbols to be the name of the section they represent.
4165 Debugging symbols begin with "L$0\001", not just "L$".
4167 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4169 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4171 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4172 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4173 and bfd_is_local_label.
4175 * targets.c: Add new entries to the bfd_target structure.
4177 * bfd.c (bfd_copy_private_bfd_data): New definition.

4185 * libbfd.c (bfd_generic_is_local_label): New function.
4187 * *-core.c: Provide default definitions for new functions in
4188 the target vector which all point to bfd_false.
4190 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4191 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4192 Default new vectors for copying private backend data to bfd_true.
4193 Default new vector for determining if a symbol is a local label
4194 to bfd_generic_is_local_label.
4196 * som.c (som_bfd_copy_private_section_data): New function.
4197 (som_bfd_is_local_label): New function.
4198 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4200 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4202 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4204 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4206 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4209 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4210 Indent some of them to GNU standards.
4212 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4213 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4214 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4215 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4216 Update copyright years.
4218 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4220 * som.c (som_prep_for_fixups): A relocation involving the section
4221 symbol for the *ABS* section is really a relocation involving
4223 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4224 undefined symbols. Correctly distinguish between debugger symbols
4225 and section symbols.
4227 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4228 for spaces and subspaces.
4230 * som.c (som_bfd_count_ar_symbols): Fix typo.
4232 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4233 HAS_RELOC based on the object's magic number.
4234 (make_unique_section): Delete function. BFD and its users are
4235 prepared to handle multiple sections with the same name.
4236 (setup_sections): Allocate space on the BFD's obstack to hold
4237 section names. Use bfd_make_setion_anyway rather than the
4238 obsolete make_unique_section.
4239 (som_prep_headers): Choose the correct SOM magic number based
4241 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4243 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4245 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4255 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4256 is always located at the start of the data section to allow
4257 recovery of the dynamic info from a stripped executable.
4258 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4261 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4263 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4264 cruft (like the #pragma alloca for AIX).
4265 In addition to that problem, the C alloca calls xmalloc, which
4266 means checking for being out of memory can't work right. The
4267 following changes remove all uses of alloca from BFD.
4268 * hosts/solaris2.h: Remove alloca cruft.
4269 * som.c: Replace alloca with a fixed size auto array.

4274 * linker.c: Replace alloca with obstack_alloc.
4275 * libbfd.h: Rebuilt.
4277 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4279 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4282 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4284 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4285 Elf*_Off typedefs by their expansion, the typedefs have been
4286 removed from include/elf/internal.h.
4287 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4288 SHT_PROGBITS section.
4290 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4292 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
4294 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4296 * configure.host: Recognize i[34]86-sequent-*.
4298 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4299 return from bfd_seek indicates an error.
4300 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4301 TRAD_CORE_STACK_OFFSET.
4302 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4303 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4305 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4307 * som.[ch]: Do not include libhppa.h in som.c, instead include

4618 bother processing them.
4619 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5106 _bfd_generic_link_write_global_symbol): Don't require that all

5322 The sparc (and possibly other?) NLM format requires a different
5323 way to write exports, so add a write_export field to the backend
5324 data (and set it to NULL for everything but the sparc).
