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

186 * libbfd-in.h (bfd_generic_is_local_label): Declare.
188 * libbfd.c (bfd_generic_is_local_label): New function.
190 * *-core.c: Provide default definitions for new functions in
191 the target vector which all point to bfd_false.
193 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
194 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
195 Default new vectors for copying private backend data to bfd_true.
196 Default new vector for determining if a symbol is a local label
197 to bfd_generic_is_local_label.
199 * som.c (som_bfd_copy_private_section_data): New function.
200 (som_bfd_is_local_label): New function.
201 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
203 * elf32-hppa.c (hppa_elf_is_local_label): New function.
205 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
207 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
209 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
212 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
213 Indent some of them to GNU standards.
215 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
216 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
217 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
218 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
219 Update copyright years.
221 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
223 * som.c (som_prep_for_fixups): A relocation involving the section
224 symbol for the *ABS* section is really a relocation involving
226 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
227 undefined symbols. Correctly distinguish between debugger symbols
230 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
231 for spaces and subspaces.
233 * som.c (som_bfd_count_ar_symbols): Fix typo.
235 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
236 HAS_RELOC based on the object's magic number.
237 (make_unique_section): Delete function. BFD and its users are
238 prepared to handle multiple sections with the same name.
239 (setup_sections): Allocate space on the BFD's obstack to hold
240 section names. Use bfd_make_setion_anyway rather than the
241 obsolete make_unique_section.
242 (som_prep_headers): Choose the correct SOM magic number based
244 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
246 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
248 * elf32-ppc.c: Renamed from elf32-powerpc.c.

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

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

303 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
304 return from bfd_seek indicates an error.
305 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
306 TRAD_CORE_STACK_OFFSET.
307 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
308 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
310 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
312 * som.[ch]: Do not include libhppa.h in som.c, instead include
315 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
316 include it in elf32-hppa.h.
318 * som.c (log2): Return -1 on error rather than aborting.
319 (setup_sections): Bubble up an error from log2.
321 * Changes to make HP C compiler happy in both traditional
323 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
325 (bfd_som_set_section_attributes): Use unsigned int rather than
326 unsigned char to avoid GNU-C extensions.
327 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
328 or failure rather than aborting on failure.
330 * som.h (bfd_som_set_section_attributes): Fix prototype to match
332 (bfd_som_attach_aux_hdr): Add prototype.
333 (hppa_som-gen_reloc_type): Likewise.
335 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
336 (hppa_look_for_stubs_in_section): Do not return false on failure

339 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
341 * bfd-in2.h: Rebuilt.

372 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
373 (hppa_elf_look_for_stubs_in_section): No longer need symbols
374 argument. Use the output symbols when canonicalizing the relocs,
375 creating them if necessary.
377 * linker.c (_bfd_generic_link_output_symbols): Do not
378 rebuild/clobber the output symbols if they already exist.
380 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
382 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
383 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
384 * bfd-in2.h: Rebuilt.
386 * srec.c (hex_value): Always set to a size of 256 bytes.
387 (srec_init): Cosmetic changes.
389 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
391 * elf32-hppa.c: Second half of major cleanup. More comments,
392 PARAMize and staticize rest of functions. Delete unused
393 functions. Delete unused/unnecessary arguments to some functions.
394 Group static vars together. Abort for bad errors until we have
395 error code propogation working. Work on spacing and indention.
396 Add FIXMEs for unresolved problems. Use enums rather than
397 #defines for lots of things. Merge two functions which build
398 linker stubs into a single function (so they can easily share a
401 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
403 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
404 avoid depending upon right shifts of signed numbers, and to
405 correct handling of src_mask with lower bits zero.

440 comments. PARAMize some static functions. Delete unused functions.
441 Delete unused/unnecessary arguments to many functions. Group
442 static vars together. Collapse common case statements together
443 in many places. Use default case when possible instead of listing
444 each case separately. Abort for bad errors until we get error
445 code propogation working. Work on spacing and indention problems.
446 Add FIXMEs for some unresolved problems. Delete hopelessly broken
447 COMPLEX relocation support (it's never used anyway).
448 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
449 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
450 (elf_hppa_tc_make_sections): Likewise.
452 * format.c (bfd_check_format_matches): Initialize matching_vector
453 to keep gcc -Wall quiet.

1192 bfd_som_set_subsection_attributes): Change parameters from char
1193 to int. Following a prototype with an old-style function definition

1300 use get_value to get the symbol value and check for undefined
1302 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1303 undefined, look it up in the linker hash table.
1305 * aoutx.h (translate_symbol_table): The string index 0 has a

1330 The sparc (and possibly other?) NLM format requires a different
1331 way to write exports, so add a write_export field to the backend
1332 data (and set it to NULL for everything but the sparc).

1382 read_dynamic_relocs fields.
1383 * aout-target.h (MY(backend_data)): Initialize
