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

152 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
154 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
155 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
156 and bfd_is_local_label.
158 * targets.c: Add new entries to the bfd_target structure.
160 * bfd.c (bfd_copy_private_bfd_data): New definition.

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

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

246 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
248 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
249 cruft (like the #pragma alloca for AIX).
250 In addition to that problem, the C alloca calls xmalloc, which
251 means checking for being out of memory can't work right. The
252 following changes remove all uses of alloca from BFD.
253 * hosts/solaris2.h: Remove alloca cruft.
254 * som.c: Replace alloca with a fixed size auto array.

269 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
270 Elf*_Off typedefs by their expansion, the typedefs have been
271 removed from include/elf/internal.h.
272 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
273 SHT_PROGBITS section.

283 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
284 return from bfd_seek indicates an error.
285 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
286 TRAD_CORE_STACK_OFFSET.
287 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
288 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
290 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
292 * som.[ch]: Do not include libhppa.h in som.c, instead include
295 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
296 include it in elf32-hppa.h.

299 (setup_sections): Bubble up an error from log2.
301 * Changes to make HP C compiler happy in both traditional
303 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
305 (bfd_som_set_section_attributes): Use unsigned int rather than
306 unsigned char to avoid GNU-C extensions.
307 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
308 or failure rather than aborting on failure.
310 * som.h (bfd_som_set_section_attributes): Fix prototype to match
312 (bfd_som_attach_aux_hdr): Add prototype.
313 (hppa_som-gen_reloc_type): Likewise.

372 PARAMize and staticize rest of functions. Delete unused
373 functions. Delete unused/unnecessary arguments to some functions.
374 Group static vars together. Abort for bad errors until we have
375 error code propogation working. Work on spacing and indention.
376 Add FIXMEs for unresolved problems. Use enums rather than
377 #defines for lots of things. Merge two functions which build
378 linker stubs into a single function (so they can easily share a

421 Delete unused/unnecessary arguments to many functions. Group
422 static vars together. Collapse common case statements together
423 in many places. Use default case when possible instead of listing
424 each case separately. Abort for bad errors until we get error
425 code propogation working. Work on spacing and indention problems.
426 Add FIXMEs for some unresolved problems. Delete hopelessly broken
427 COMPLEX relocation support (it's never used anyway).
428 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
429 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).

1094 _bfd_generic_link_write_global_symbol): Don't require that all

1172 bfd_som_set_subsection_attributes): Change parameters from char
1173 to int. Following a prototype with an old-style function definition

1280 use get_value to get the symbol value and check for undefined
1282 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1283 undefined, look it up in the linker hash table.
1285 * aoutx.h (translate_symbol_table): The string index 0 has a

1310 The sparc (and possibly other?) NLM format requires a different
1311 way to write exports, so add a write_export field to the backend
1312 data (and set it to NULL for everything but the sparc).

1362 read_dynamic_relocs fields.
1363 * aout-target.h (MY(backend_data)): Initialize
