3 Support for link_order types which generate relocs in order to
4 support -Ur in the linker.
5 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
6 from call to _bfd_generic_link_add_one_symbol.
7 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
8 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
9 instead of bitsize to add_to_set call back.
10 (_bfd_generic_final_link): Account for link_order relocs when
11 allocating space for relocations. Handle them in link_order loop.
12 (_bfd_generic_reloc_link_order): New function.
13 (_bfd_default_link_order): If a reloc_link_order is seen here,
15 (_bfd_count_link_order_relocs): New function.
16 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
17 argument from declaration.
18 (_bfd_generic_reloc_link_order): Declare.
19 (_bfd_count_link_order_relocs): Declare.
21 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
22 call to _bfd_generic_link_add_one_symbol.
23 (NAME(aout,final_link)): Account for link_order relocs when
24 allocating space for relocations. Handle them after handling all
26 (aout_link_reloc_link_order): New function.
27 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
28 call to _bfd_generic_link_add_one_symbol.
29 (ecoff_bfd_final_link): Account for link_order relocs when
30 allocating space for relocations. Handle them in link_order loop.
31 (ecoff_link_write_external): Set the storage class of a defined
32 linker created symbol based on the section it is in. Correct
33 bfd_link_hash_weak case to use .sc rather than .st.
34 (ecoff_reloc_link_order): New function.
35 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
37 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
39 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
42 * cisco-core.c (cisco_core_file_p): Only pass one argument to
43 bfd_zmalloc. Free a pointer, not a union.
44 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
46 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
48 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
50 * som.c (bfd_section_from_som_symbol): Only to do the value
51 comparison for function symbols within executables.
53 * som.c (bfd_section_from_som_symbol): Renamed from
54 som_section_from_subspace_index. Pass in a native SOM symbol.
55 For executables, iterate through the sections to find out
56 which contains the symbol's address rather than using the
57 symbol_info field. (symbol_info has a different meaning for
58 dynamicly linked executables.)
60 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
63 * som.c (som_begin_writing): Fix braino (one call to align
64 space/subspace data was done unconditionally rather than
65 just for executables.)
67 * som.c (som_begin_writing): Align text in all executables to
68 make HPUX kernel happy. Fixes strip/objcopy for shared
71 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
73 * som.c (som_begin_writing): Account for alignment needs of
74 subspaces too when writing executables. Never request a negative
75 bss size. Fixes some problems with demand paged executables,
76 still having problems with pure executables and shared executables.
78 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
80 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
81 bfd_zalloc for rawptr, because later on we may call free, not
84 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
85 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
86 * cisco-core.c: New file.
87 * Makefile.in: Change accordingly.
88 * configure.in: Recognize cisco_core_vec.
89 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
90 * targets.c: Add cisco_core_vec.
93 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
95 * som.h (som_copyable_section_data_struct): New structure
96 containing all the private section information which needs
97 to be copied from input section to output section during
99 (som_section_data_struct): Remove several fields now in
100 som_copyable_section_data_struct. Make the space and
101 subspace dictionaries be pointers (to save space when
102 only reading objects).
104 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
105 some references changed. Allocate a copyable data stucture if
106 none exists. Store info into the copyable data structure.
107 (bfd_som_set_subsection_attributes): Likewise.
108 (som_is_space, som_is_subspace, som_is_container): New functions.
109 Use these instead of directly accessing private data.
110 (som_prep_headers): Allocate space and subspace headers here.
111 Fill in some fields in the space/subspace headers from the
113 (som_bfd_copy_private_section_data): Only copy the stuff
114 that we really need to make objcopy and strip work. Allocate
115 the copy_data structure for the output bfd before copying.
117 * som.h (struct som_exec_data): New structure to hold exec
118 info that must be preserved when running objcopy/strip.
119 (struct somdata): Add new "exec_data" field and accessor
120 macro. Add some comments on how the various fields are used.
121 (som_section_data_struct): Make is_space and is_subspace bitfields.
122 Delete unused subspace_index. All references now use the
123 target_index field within the section structure itself.
125 * som.c (make_unique_section): Delete unused declaration.
126 (som_bfd_copy_private_bfd_data): New function.
127 (som_object_setup): Allocate space for and save exec information
128 that needs to be copied during objcopy/strip.
129 (som_mkobject): Do not allocate space for a file header here.
130 It is not used when only reading SOM objects.
131 (som_prep_headers): Allocate space for and attach a file header
132 to the output bfd. For executables, use the saved system_id
133 value rather than trying to guess the right value. Do not abort
134 wwhen setting file_hdr->entry* for executables.
135 (som_begin_writing): For executables, set the exec_entry and
137 (som_copy_private_backend_section_data): Always return a value.
139 * libhppa.h (PA_PAGESIZE): Define.
141 * som.c (SOM_ALIGN): Define.
142 (som_begin_writing): If writing an executable, initialize all
143 fields in the exec header to zero. Update fields in the exec
144 header as sizes of loadable subspaces are computed. Carefully
145 preserve alignments when building executables. Actually write the
146 exec after all the fields are filled in.
148 * Better long-filename handling. Reads SOM ABI compliant extended
149 names, but doesn't quite write compliant extended names yet.
150 * som.c (som_slurp_extended_name_table): Delete function. The
151 generic code will handle things correctly.
152 (som_slurp_armap): Seek to the beginning of the next member.
153 (normalize): New function.
154 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
155 name table into account when computing the file offsets in the
156 SOM dictionary. Make sure to align to an even boundary.
157 (som_write_armap): Initialize the checksum to zero.
158 (ar_maxchars): Fix. Opps.
160 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
162 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
163 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
165 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
167 * bfd-in.h (BFD_VERSION): Use @VERSION@.
168 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
169 * bfd-in2.h: Regenerated.
171 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
172 this was also named trad_unix_bfd_copy_private_bfd_data.
174 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
176 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
177 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
178 returns NULL, it is not an error. It's possible that some of
179 these checks are not necessary (because the size can never be
180 zero), but putting in the checks is the conservative thing to do
181 in light of the fact that some of these malloc calls replaced
182 unchecked alloca calls, in which a zero argument would work fine.
184 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
186 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
187 duplicate definition.
188 (osf_core_bfd_is_local_label): Define.
190 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
191 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
192 failure indication, it merely means there are no relocs.
194 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
195 after NAME, since SunOS /bin/cc can't handle it.
197 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
199 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
200 From sukes@glue.umd.edu (Tasuki Hirata).
202 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
204 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
205 all that convoluted stuff with NAME, CAT3, etc. The convoluted
206 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
208 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
210 * som.c (som_prep_for_fixups): Detect section symbols based
211 on either the lack of private data or the symbol flags. Do not
212 munge section symbol names anymore -- they no longer confuse GDB.
213 (som_begin_writing): Leave space for an exec header if writing
215 (som_slurp_symbol_table): Recognize both forms of section symbol
216 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
217 section symbols to be the name of the section they represent.
218 Debugging symbols begin with "L$0\001", not just "L$".
220 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
222 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
224 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
225 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
226 and bfd_is_local_label.
228 * targets.c: Add new entries to the bfd_target structure.
230 * bfd.c (bfd_copy_private_bfd_data): New definition.
232 * section.c (bfd_copy_private_section_data): New definition.
234 * syms.c (bfd_is_local_label): New definition.
236 * libbfd-in.h (bfd_generic_is_local_label): Declare.
238 * libbfd.c (bfd_generic_is_local_label): New function.
240 * *-core.c: Provide default definitions for new functions in
241 the target vector which all point to bfd_false.
243 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
244 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
245 Default new vectors for copying private backend data to bfd_true.
246 Default new vector for determining if a symbol is a local label
247 to bfd_generic_is_local_label.
249 * som.c (som_bfd_copy_private_section_data): New function.
250 (som_bfd_is_local_label): New function.
251 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
253 * elf32-hppa.c (hppa_elf_is_local_label): New function.
255 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
257 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
259 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
262 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
263 Indent some of them to GNU standards.
265 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
266 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
267 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
268 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
269 Update copyright years.
271 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
273 * som.c (som_prep_for_fixups): A relocation involving the section
274 symbol for the *ABS* section is really a relocation involving
276 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
277 undefined symbols. Correctly distinguish between debugger symbols
280 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
281 for spaces and subspaces.
283 * som.c (som_bfd_count_ar_symbols): Fix typo.
285 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
286 HAS_RELOC based on the object's magic number.
287 (make_unique_section): Delete function. BFD and its users are
288 prepared to handle multiple sections with the same name.
289 (setup_sections): Allocate space on the BFD's obstack to hold
290 section names. Use bfd_make_setion_anyway rather than the
291 obsolete make_unique_section.
292 (som_prep_headers): Choose the correct SOM magic number based
294 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
296 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
298 * elf32-ppc.c: Renamed from elf32-powerpc.c.

308 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
310 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
311 is always located at the start of the data section to allow
312 recovery of the dynamic info from a stripped executable.
313 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
316 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
318 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
319 cruft (like the #pragma alloca for AIX).
320 In addition to that problem, the C alloca calls xmalloc, which
321 means checking for being out of memory can't work right. The
322 following changes remove all uses of alloca from BFD.
323 * hosts/solaris2.h: Remove alloca cruft.
324 * som.c: Replace alloca with a fixed size auto array.
325 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
326 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,

337 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
339 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
340 Elf*_Off typedefs by their expansion, the typedefs have been
341 removed from include/elf/internal.h.
342 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
343 SHT_PROGBITS section.
345 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
347 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
349 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
351 * configure.host: Recognize i[34]86-sequent-*.
353 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
354 return from bfd_seek indicates an error.
355 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
356 TRAD_CORE_STACK_OFFSET.
357 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
358 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
360 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
362 * som.[ch]: Do not include libhppa.h in som.c, instead include
365 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
366 include it in elf32-hppa.h.
368 * som.c (log2): Return -1 on error rather than aborting.
369 (setup_sections): Bubble up an error from log2.
371 * Changes to make HP C compiler happy in both traditional
373 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
375 (bfd_som_set_section_attributes): Use unsigned int rather than
376 unsigned char to avoid GNU-C extensions.
377 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
378 or failure rather than aborting on failure.
380 * som.h (bfd_som_set_section_attributes): Fix prototype to match
382 (bfd_som_attach_aux_hdr): Add prototype.
383 (hppa_som-gen_reloc_type): Likewise.
385 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
386 (hppa_look_for_stubs_in_section): Do not return false on failure

389 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
391 * bfd-in2.h: Rebuilt.
393 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

417 unused symbols argument.
419 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
420 than asymbol * for original target symbol. All callers changed.
421 Set reloc->sym_ptr_ptr appropriately.
422 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
423 (hppa_elf_look_for_stubs_in_section): No longer need symbols
424 argument. Use the output symbols when canonicalizing the relocs,
425 creating them if necessary.
427 * linker.c (_bfd_generic_link_output_symbols): Do not
428 rebuild/clobber the output symbols if they already exist.
430 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
432 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
433 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
434 * bfd-in2.h: Rebuilt.
436 * srec.c (hex_value): Always set to a size of 256 bytes.
437 (srec_init): Cosmetic changes.
439 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
441 * elf32-hppa.c: Second half of major cleanup. More comments,
442 PARAMize and staticize rest of functions. Delete unused
443 functions. Delete unused/unnecessary arguments to some functions.
444 Group static vars together. Abort for bad errors until we have
445 error code propogation working. Work on spacing and indention.
446 Add FIXMEs for unresolved problems. Use enums rather than
447 #defines for lots of things. Merge two functions which build
448 linker stubs into a single function (so they can easily share a
451 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
453 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
454 avoid depending upon right shifts of signed numbers, and to
455 correct handling of src_mask with lower bits zero.
457 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
458 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

1347 (get_value): If the symbol is undefined, look it up in the linker
1349 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
1350 use get_value to get the symbol value and check for undefined
1352 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1353 undefined, look it up in the linker hash table.
1355 * aoutx.h (translate_symbol_table): The string index 0 has a

1380 The sparc (and possibly other?) NLM format requires a different
1381 way to write exports, so add a write_export field to the backend
1382 data (and set it to NULL for everything but the sparc).
