1 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
6 * som.c (som_begin_writing): Fix braino (one call to align
7 space/subspace data was done unconditionally rather than
10 * som.c (som_begin_writing): Align text in all executables to
11 make HPUX kernel happy. Fixes strip/objcopy for shared
14 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
16 * som.c (som_begin_writing): Account for alignment needs of
17 subspaces too when writing executables. Never request a negative
18 bss size. Fixes some problems with demand paged executables,
19 still having problems with pure executables and shared executables.
21 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
23 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
24 bfd_zalloc for rawptr, because later on we may call free, not
27 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
28 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
29 * cisco-core.c: New file.
30 * Makefile.in: Change accordingly.
31 * configure.in: Recognize cisco_core_vec.
32 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
33 * targets.c: Add cisco_core_vec.
36 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
38 * som.h (som_copyable_section_data_struct): New structure
39 containing all the private section information which needs
40 to be copied from input section to output section during
42 (som_section_data_struct): Remove several fields now in
43 som_copyable_section_data_struct. Make the space and
44 subspace dictionaries be pointers (to save space when
45 only reading objects).
47 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
48 some references changed. Allocate a copyable data stucture if
49 none exists. Store info into the copyable data structure.
50 (bfd_som_set_subsection_attributes): Likewise.
51 (som_is_space, som_is_subspace, som_is_container): New functions.
52 Use these instead of directly accessing private data.
53 (som_prep_headers): Allocate space and subspace headers here.
54 Fill in some fields in the space/subspace headers from the
56 (som_bfd_copy_private_section_data): Only copy the stuff
57 that we really need to make objcopy and strip work. Allocate
58 the copy_data structure for the output bfd before copying.
60 * som.h (struct som_exec_data): New structure to hold exec
61 info that must be preserved when running objcopy/strip.
62 (struct somdata): Add new "exec_data" field and accessor
63 macro. Add some comments on how the various fields are used.
64 (som_section_data_struct): Make is_space and is_subspace bitfields.
65 Delete unused subspace_index. All references now use the
66 target_index field within the section structure itself.
68 * som.c (make_unique_section): Delete unused declaration.
69 (som_bfd_copy_private_bfd_data): New function.
70 (som_object_setup): Allocate space for and save exec information
71 that needs to be copied during objcopy/strip.
72 (som_mkobject): Do not allocate space for a file header here.
73 It is not used when only reading SOM objects.
74 (som_prep_headers): Allocate space for and attach a file header
75 to the output bfd. For executables, use the saved system_id
76 value rather than trying to guess the right value. Do not abort
77 wwhen setting file_hdr->entry* for executables.
78 (som_begin_writing): For executables, set the exec_entry and
80 (som_copy_private_backend_section_data): Always return a value.
82 * libhppa.h (PA_PAGESIZE): Define.
84 * som.c (SOM_ALIGN): Define.
85 (som_begin_writing): If writing an executable, initialize all
86 fields in the exec header to zero. Update fields in the exec
87 header as sizes of loadable subspaces are computed. Carefully
88 preserve alignments when building executables. Actually write the
89 exec after all the fields are filled in.
91 * Better long-filename handling. Reads SOM ABI compliant extended
92 names, but doesn't quite write compliant extended names yet.
93 * som.c (som_slurp_extended_name_table): Delete function. The
94 generic code will handle things correctly.
95 (som_slurp_armap): Seek to the beginning of the next member.
96 (normalize): New function.
97 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
98 name table into account when computing the file offsets in the
99 SOM dictionary. Make sure to align to an even boundary.
100 (som_write_armap): Initialize the checksum to zero.
101 (ar_maxchars): Fix. Opps.
103 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
105 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
106 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
108 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
110 * bfd-in.h (BFD_VERSION): Use @VERSION@.
111 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
112 * bfd-in2.h: Regenerated.
114 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
115 this was also named trad_unix_bfd_copy_private_bfd_data.
117 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
119 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
120 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
121 returns NULL, it is not an error. It's possible that some of
122 these checks are not necessary (because the size can never be
123 zero), but putting in the checks is the conservative thing to do
124 in light of the fact that some of these malloc calls replaced
125 unchecked alloca calls, in which a zero argument would work fine.
127 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
129 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
130 duplicate definition.
131 (osf_core_bfd_is_local_label): Define.
133 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
134 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
135 failure indication, it merely means there are no relocs.
137 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
138 after NAME, since SunOS /bin/cc can't handle it.
140 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
142 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
143 From sukes@glue.umd.edu (Tasuki Hirata).
145 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
147 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
148 all that convoluted stuff with NAME, CAT3, etc. The convoluted
149 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
151 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
153 * som.c (som_prep_for_fixups): Detect section symbols based
154 on either the lack of private data or the symbol flags. Do not
155 munge section symbol names anymore -- they no longer confuse GDB.
156 (som_begin_writing): Leave space for an exec header if writing
158 (som_slurp_symbol_table): Recognize both forms of section symbol
159 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
160 section symbols to be the name of the section they represent.
161 Debugging symbols begin with "L$0\001", not just "L$".
163 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
165 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
167 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
168 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
169 and bfd_is_local_label.
171 * targets.c: Add new entries to the bfd_target structure.
173 * bfd.c (bfd_copy_private_bfd_data): New definition.
175 * section.c (bfd_copy_private_section_data): New definition.
177 * syms.c (bfd_is_local_label): New definition.
179 * libbfd-in.h (bfd_generic_is_local_label): Declare.
181 * libbfd.c (bfd_generic_is_local_label): New function.
183 * *-core.c: Provide default definitions for new functions in
184 the target vector which all point to bfd_false.

187 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
188 Default new vectors for copying private backend data to bfd_true.
189 Default new vector for determining if a symbol is a local label
190 to bfd_generic_is_local_label.
192 * som.c (som_bfd_copy_private_section_data): New function.
193 (som_bfd_is_local_label): New function.
194 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
196 * elf32-hppa.c (hppa_elf_is_local_label): New function.
198 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
200 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
202 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
205 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
206 Indent some of them to GNU standards.
208 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
209 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
210 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
211 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
212 Update copyright years.
214 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
216 * som.c (som_prep_for_fixups): A relocation involving the section
217 symbol for the *ABS* section is really a relocation involving
219 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
220 undefined symbols. Correctly distinguish between debugger symbols
223 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
224 for spaces and subspaces.
226 * som.c (som_bfd_count_ar_symbols): Fix typo.
228 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
229 HAS_RELOC based on the object's magic number.
230 (make_unique_section): Delete function. BFD and its users are
231 prepared to handle multiple sections with the same name.
232 (setup_sections): Allocate space on the BFD's obstack to hold
233 section names. Use bfd_make_setion_anyway rather than the
234 obsolete make_unique_section.
235 (som_prep_headers): Choose the correct SOM magic number based
237 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
239 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
241 * elf32-ppc.c: Renamed from elf32-powerpc.c.

259 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
261 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
262 cruft (like the #pragma alloca for AIX).
263 In addition to that problem, the C alloca calls xmalloc, which
264 means checking for being out of memory can't work right. The
265 following changes remove all uses of alloca from BFD.
266 * hosts/solaris2.h: Remove alloca cruft.
267 * som.c: Replace alloca with a fixed size auto array.
268 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

282 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
283 Elf*_Off typedefs by their expansion, the typedefs have been
284 removed from include/elf/internal.h.
285 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
286 SHT_PROGBITS section.
288 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

296 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
297 return from bfd_seek indicates an error.
298 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
299 TRAD_CORE_STACK_OFFSET.
300 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
301 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
303 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
305 * som.[ch]: Do not include libhppa.h in som.c, instead include
308 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
309 include it in elf32-hppa.h.
311 * som.c (log2): Return -1 on error rather than aborting.
312 (setup_sections): Bubble up an error from log2.
314 * Changes to make HP C compiler happy in both traditional
316 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
318 (bfd_som_set_section_attributes): Use unsigned int rather than
319 unsigned char to avoid GNU-C extensions.
320 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
321 or failure rather than aborting on failure.
323 * som.h (bfd_som_set_section_attributes): Fix prototype to match
325 (bfd_som_attach_aux_hdr): Add prototype.
326 (hppa_som-gen_reloc_type): Likewise.
328 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
329 (hppa_look_for_stubs_in_section): Do not return false on failure
330 until rest of code is ready to handle it. Abort for now.
332 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
334 * bfd-in2.h: Rebuilt.

366 (hppa_elf_look_for_stubs_in_section): No longer need symbols
367 argument. Use the output symbols when canonicalizing the relocs,

370 * linker.c (_bfd_generic_link_output_symbols): Do not
371 rebuild/clobber the output symbols if they already exist.
373 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
375 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
376 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
377 * bfd-in2.h: Rebuilt.
379 * srec.c (hex_value): Always set to a size of 256 bytes.
380 (srec_init): Cosmetic changes.
382 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
384 * elf32-hppa.c: Second half of major cleanup. More comments,
385 PARAMize and staticize rest of functions. Delete unused
386 functions. Delete unused/unnecessary arguments to some functions.
387 Group static vars together. Abort for bad errors until we have
388 error code propogation working. Work on spacing and indention.
389 Add FIXMEs for unresolved problems. Use enums rather than
390 #defines for lots of things. Merge two functions which build
391 linker stubs into a single function (so they can easily share a
394 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
396 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
397 avoid depending upon right shifts of signed numbers, and to
398 correct handling of src_mask with lower bits zero.

433 comments. PARAMize some static functions. Delete unused functions.
434 Delete unused/unnecessary arguments to many functions. Group
435 static vars together. Collapse common case statements together
436 in many places. Use default case when possible instead of listing
437 each case separately. Abort for bad errors until we get error
438 code propogation working. Work on spacing and indention problems.
439 Add FIXMEs for some unresolved problems. Delete hopelessly broken
440 COMPLEX relocation support (it's never used anyway).
441 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
442 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
443 (elf_hppa_tc_make_sections): Likewise.

486 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
487 number rather than HP9000S800_ID. Note som.c is careful
488 to make sure CPU_PA_RISC1_0 is always defined.

1033 * srec.c (srec_write_record): Put CONST keyword for "src" before
1034 "unsigned", some compilers don't like it after "unsigned".
1035 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

1107 _bfd_generic_link_write_global_symbol): Don't require that all

1185 bfd_som_set_subsection_attributes): Change parameters from char
1186 to int. Following a prototype with an old-style function definition

1290 (get_value): If the symbol is undefined, look it up in the linker
1292 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
1293 use get_value to get the symbol value and check for undefined
1295 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1296 undefined, look it up in the linker hash table.
1298 * aoutx.h (translate_symbol_table): The string index 0 has a

1323 The sparc (and possibly other?) NLM format requires a different
1324 way to write exports, so add a write_export field to the backend
1325 data (and set it to NULL for everything but the sparc).

1375 read_dynamic_relocs fields.
1376 * aout-target.h (MY(backend_data)): Initialize
