3894 in asymbol udata field.
3896 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3898 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3899 reloc, used in embedded PIC code.
3900 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

3908 add_symbls entry point.
3910 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3911 counting relocs. Set SEC_RELOC flag for any section which has

3917 generic_link_add_symbols.
3918 (_bfd_generic_link_add_symbols_collect): New function, like
3919 _bfd_generic_link_add_symbols but also collect constructors and
3920 destructors by name as collect2 does.
3921 (generic_link_add_symbols): New function, like old
3922 _bfd_generic_link_add_symbols but with collect argument.
3923 (generic_link_add_object_symbols): Take collect argument.

3935 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
3936 for first character in an extended name.
3937 (_bfd_write_archive_contents): If ar_padchar == '/', then use
3938 "//" as the name of the special archive member holding the
3939 extended name table.
3941 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3943 Support for link_order types which generate relocs in order to
3944 support -Ur in the linker.
3945 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3946 from call to _bfd_generic_link_add_one_symbol.
3947 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3948 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3949 instead of bitsize to add_to_set call back.
3950 (_bfd_generic_final_link): Account for link_order relocs when
3951 allocating space for relocations. Handle them in link_order loop.
3952 (_bfd_generic_reloc_link_order): New function.

3957 argument from declaration.
3958 (_bfd_generic_reloc_link_order): Declare.

3968 call to _bfd_generic_link_add_one_symbol.
3969 (ecoff_bfd_final_link): Account for link_order relocs when
3970 allocating space for relocations. Handle them in link_order loop.
3971 (ecoff_link_write_external): Set the storage class of a defined
3972 linker created symbol based on the section it is in. Correct
3973 bfd_link_hash_weak case to use .sc rather than .st.
3974 (ecoff_reloc_link_order): New function.
3975 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3977 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3986 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3988 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3990 * som.c (bfd_section_from_som_symbol): Only to do the value
3991 comparison for function symbols within executables.
3993 * som.c (bfd_section_from_som_symbol): Renamed from
3994 som_section_from_subspace_index. Pass in a native SOM symbol.
3995 For executables, iterate through the sections to find out
3996 which contains the symbol's address rather than using the
3997 symbol_info field. (symbol_info has a different meaning for
3998 dynamicly linked executables.)
4000 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4003 * som.c (som_begin_writing): Fix braino (one call to align
4004 space/subspace data was done unconditionally rather than
4005 just for executables.)
4007 * som.c (som_begin_writing): Align text in all executables to
4008 make HPUX kernel happy. Fixes strip/objcopy for shared
4011 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4013 * som.c (som_begin_writing): Account for alignment needs of
4014 subspaces too when writing executables. Never request a negative
4015 bss size. Fixes some problems with demand paged executables,
4016 still having problems with pure executables and shared executables.
4018 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4020 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4021 bfd_zalloc for rawptr, because later on we may call free, not
4024 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4025 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4026 * cisco-core.c: New file.
4027 * Makefile.in: Change accordingly.
4028 * configure.in: Recognize cisco_core_vec.
4029 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4030 * targets.c: Add cisco_core_vec.
4031 * bfd-in2.h: Rebuilt.
4033 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4035 * som.h (som_copyable_section_data_struct): New structure
4036 containing all the private section information which needs
4037 to be copied from input section to output section during
4039 (som_section_data_struct): Remove several fields now in
4040 som_copyable_section_data_struct. Make the space and
4041 subspace dictionaries be pointers (to save space when
4042 only reading objects).
4044 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4045 some references changed. Allocate a copyable data stucture if
4046 none exists. Store info into the copyable data structure.
4047 (bfd_som_set_subsection_attributes): Likewise.
4048 (som_is_space, som_is_subspace, som_is_container): New functions.
4049 Use these instead of directly accessing private data.
4050 (som_prep_headers): Allocate space and subspace headers here.
4051 Fill in some fields in the space/subspace headers from the
4053 (som_bfd_copy_private_section_data): Only copy the stuff
4054 that we really need to make objcopy and strip work. Allocate
4055 the copy_data structure for the output bfd before copying.
4057 * som.h (struct som_exec_data): New structure to hold exec
4058 info that must be preserved when running objcopy/strip.
4059 (struct somdata): Add new "exec_data" field and accessor
4060 macro. Add some comments on how the various fields are used.
4061 (som_section_data_struct): Make is_space and is_subspace bitfields.
4062 Delete unused subspace_index. All references now use the
4063 target_index field within the section structure itself.
4065 * som.c (make_unique_section): Delete unused declaration.
4066 (som_bfd_copy_private_bfd_data): New function.
4067 (som_object_setup): Allocate space for and save exec information
4068 that needs to be copied during objcopy/strip.
4069 (som_mkobject): Do not allocate space for a file header here.
4070 It is not used when only reading SOM objects.
4071 (som_prep_headers): Allocate space for and attach a file header
4072 to the output bfd. For executables, use the saved system_id
4073 value rather than trying to guess the right value. Do not abort
4074 wwhen setting file_hdr->entry* for executables.
4075 (som_begin_writing): For executables, set the exec_entry and
4077 (som_copy_private_backend_section_data): Always return a value.
4079 * libhppa.h (PA_PAGESIZE): Define.
4081 * som.c (SOM_ALIGN): Define.
4082 (som_begin_writing): If writing an executable, initialize all
4083 fields in the exec header to zero. Update fields in the exec
4084 header as sizes of loadable subspaces are computed. Carefully
4085 preserve alignments when building executables. Actually write the
4086 exec after all the fields are filled in.
4088 * Better long-filename handling. Reads SOM ABI compliant extended
4089 names, but doesn't quite write compliant extended names yet.
4090 * som.c (som_slurp_extended_name_table): Delete function. The
4091 generic code will handle things correctly.
4092 (som_slurp_armap): Seek to the beginning of the next member.
4093 (normalize): New function.
4094 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4095 name table into account when computing the file offsets in the
4096 SOM dictionary. Make sure to align to an even boundary.
4097 (som_write_armap): Initialize the checksum to zero.
4098 (ar_maxchars): Fix. Opps.
4100 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4102 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4103 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4105 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4107 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4108 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4109 * bfd-in2.h: Regenerated.
4111 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4112 this was also named trad_unix_bfd_copy_private_bfd_data.
4114 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4116 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4117 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4118 returns NULL, it is not an error. It's possible that some of
4119 these checks are not necessary (because the size can never be
4120 zero), but putting in the checks is the conservative thing to do
4121 in light of the fact that some of these malloc calls replaced
4122 unchecked alloca calls, in which a zero argument would work fine.
4124 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4126 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4127 duplicate definition.
4128 (osf_core_bfd_is_local_label): Define.
4130 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4131 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4132 failure indication, it merely means there are no relocs.
4134 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4135 after NAME, since SunOS /bin/cc can't handle it.
4137 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4139 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4140 From sukes@glue.umd.edu (Tasuki Hirata).
4142 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4144 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4145 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4146 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4148 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4150 * som.c (som_prep_for_fixups): Detect section symbols based
4151 on either the lack of private data or the symbol flags. Do not
4152 munge section symbol names anymore -- they no longer confuse GDB.
4153 (som_begin_writing): Leave space for an exec header if writing
4155 (som_slurp_symbol_table): Recognize both forms of section symbol
4156 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4157 section symbols to be the name of the section they represent.
4158 Debugging symbols begin with "L$0\001", not just "L$".
4160 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4162 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4164 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4165 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4166 and bfd_is_local_label.
4168 * targets.c: Add new entries to the bfd_target structure.
4170 * bfd.c (bfd_copy_private_bfd_data): New definition.
4172 * section.c (bfd_copy_private_section_data): New definition.

4178 * libbfd.c (bfd_generic_is_local_label): New function.
4180 * *-core.c: Provide default definitions for new functions in
4181 the target vector which all point to bfd_false.
4183 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4184 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4185 Default new vectors for copying private backend data to bfd_true.
4186 Default new vector for determining if a symbol is a local label
4187 to bfd_generic_is_local_label.
4189 * som.c (som_bfd_copy_private_section_data): New function.
4190 (som_bfd_is_local_label): New function.
4191 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4193 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4195 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4197 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4199 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4202 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4203 Indent some of them to GNU standards.
4205 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4206 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4207 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4208 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4209 Update copyright years.
4211 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4213 * som.c (som_prep_for_fixups): A relocation involving the section
4214 symbol for the *ABS* section is really a relocation involving
4216 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4217 undefined symbols. Correctly distinguish between debugger symbols
4218 and section symbols.
4220 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4221 for spaces and subspaces.
4223 * som.c (som_bfd_count_ar_symbols): Fix typo.
4225 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4226 HAS_RELOC based on the object's magic number.
4227 (make_unique_section): Delete function. BFD and its users are
4228 prepared to handle multiple sections with the same name.
4229 (setup_sections): Allocate space on the BFD's obstack to hold
4230 section names. Use bfd_make_setion_anyway rather than the
4231 obsolete make_unique_section.
4232 (som_prep_headers): Choose the correct SOM magic number based
4234 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4236 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4238 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4248 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4249 is always located at the start of the data section to allow
4250 recovery of the dynamic info from a stripped executable.
4251 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4254 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4256 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4257 cruft (like the #pragma alloca for AIX).
4258 In addition to that problem, the C alloca calls xmalloc, which
4259 means checking for being out of memory can't work right. The
4260 following changes remove all uses of alloca from BFD.
4261 * hosts/solaris2.h: Remove alloca cruft.
4262 * som.c: Replace alloca with a fixed size auto array.

4267 * linker.c: Replace alloca with obstack_alloc.
4268 * libbfd.h: Rebuilt.
4270 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4272 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4275 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4277 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4278 Elf*_Off typedefs by their expansion, the typedefs have been
4279 removed from include/elf/internal.h.
4280 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4281 SHT_PROGBITS section.
4283 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4285 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4289 * configure.host: Recognize i[34]86-sequent-*.
4291 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4292 return from bfd_seek indicates an error.
4293 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4294 TRAD_CORE_STACK_OFFSET.
4295 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4296 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4298 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4300 * som.[ch]: Do not include libhppa.h in som.c, instead include
4303 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4304 include it in elf32-hppa.h.
4306 * som.c (log2): Return -1 on error rather than aborting.

4611 bother processing them.
4612 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5315 The sparc (and possibly other?) NLM format requires a different
5316 way to write exports, so add a write_export field to the backend
5317 data (and set it to NULL for everything but the sparc).
