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

193 * *-core.c: Provide default definitions for new functions in
194 the target vector which all point to bfd_false.

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

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

292 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
293 Elf*_Off typedefs by their expansion, the typedefs have been
294 removed from include/elf/internal.h.
295 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
296 SHT_PROGBITS section.

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

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

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

1117 _bfd_generic_link_write_global_symbol): Don't require that all

1195 bfd_som_set_subsection_attributes): Change parameters from char
1196 to int. Following a prototype with an old-style function definition

1303 use get_value to get the symbol value and check for undefined
1305 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1306 undefined, look it up in the linker hash table.
1308 * aoutx.h (translate_symbol_table): The string index 0 has a

1333 The sparc (and possibly other?) NLM format requires a different
1334 way to write exports, so add a write_export field to the backend
1335 data (and set it to NULL for everything but the sparc).

1385 read_dynamic_relocs fields.
1386 * aout-target.h (MY(backend_data)): Initialize
