36
37 Sat Feb 5 05:32:44 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
38
39 * srec.c (srec_write_record): Put CONST keyword for "src" before
40 "unsigned", some compilers don't like it after "unsigned".
41 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to
42 "val" in prototype declaration because some compilers don't like
43 arguments whose names are the same as types.
44
45 Sat Feb 5 01:14:38 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
46
47 * aoutx.h (aout_link_check_ar_symbols): Correct test for whether

52
53 Add basic support for writing RS/6000 XCOFF files.
54 * coff-rs6000.c (dummy_reloc): Removed.
55 (rs6000coff_howto_table): Defined XCOFF relocs.
56 (RTYPE2HOWTO): Defined to use rs6000coff_rtype2howto.
57 (rs6000coff_rtype2howto): New function.
58 (coff_bfd_reloc_type_lookup): Defined to use
59 rs6000coff_reloc_type_lookup.
60 (rs6000coff_reloc_type_lookup): New function.
61 (SELECT_RELOC): Defined to set r_type and r_size fields.
62 (COFF_LONG_FILENAMES): Defined.
63 * coffcode.h (combined_entry_type): Changed fix_tag and fix_end
64 fields to bitfields. Added fields fix_value and fix_scnlen.
65 (sec_to_styp_flags): If STYP_DEBUG is defined, use it rather than
66 STYP_INFO for the type of a section named .debug.
67 (coff_add_missing_symbols): Don't define if RS6000COFF_C.
68 (coff_write_object_contents): If RS6000COFF_C, don't call
69 coff_add_missing_symbols.
70 (coff_slurp_symbol_table): If RS6000COFF_C, then if the last aux
71 entry has type STY_LD change the x_scnlen into a pointer to a
72 symbol and set fix_scnlen. Also, for a C_BSTAT symbol, change the
73 value into a pointer to a symbol and set fix_value.
74 * libcoff.h: Rebuilt.
75 * coffgen.c (coff_mangle_symbols): Reindent. If fix_value is set,
76 get the symbol offset. Likewise for fix_scnlen.
77 (string_size): Change type to bfd_size_type.
78 (debug_string_size, debug_string_section): New static variables.
79 (coff_fix_symbol_name): If bfd_coff_symname_in_debug returns true,
80 write the symbol name into the .debug section; assume that the
81 section has already been created with the right size.
82 (coff_write_symbols): Initialize debug_string_size to 0. If
83 bfd_coff_symname_in_debug returns true, don't put symbol name in
84 usual string table. After writing out all symbols, if
85 debug_string_size is not 0, check that it matches the size of the
86 .debug section.
87 (coff_get_normalized_symtab): Clear new fix_value and fix_scnlen
88 fields. If the string offset is 0, always use an empty string as
89 the name.
90 (coff_make_empty_symbol): Zero out the symbol structure.
91 * reloc.c (bfd_perform_relocation): Work around one gross hack
92 with another: actually look at the target name to avoid the broken
93 COFF check.
94 (bfd_reloc_code_real_type): Add BFD_RELOC_PPC_B26,
95 BFD_RELOC_PPC_BA26 and BFD_RELOC_PPC_TOC16.

101 (bfd_xmalloc, bfd_xmalloc_by_size_t): Functions deleted.
102 * libbfd-in.h: Define them as macros calling xmalloc and declare
103 xmalloc.
104 * libbfd.h: Rebuilt.

107
108 * ecofflink.c (bfd_ecoff_debug_externals): If a small undefined
109 symbol has a value in the ECOFF symbol but not in the BFD symbol,
110 keep the value in the ECOFF symbol. This helps gas.
111
112 * linker.c (_bfd_generic_link_output_symbols,
113 _bfd_generic_link_write_global_symbol): Don't require that all
114 references to a common symbol be themselves common symbols.

127 and size correctly.
128 (coff_swap_aux_in): If RS6000COFF_C, change x_csect.x_scnlen to
129 x_csect.x_scnlen.l to match change in coff/internal.h.
130 (coff_swap_aux_out): Likewise.
131
132 * coff-mips.c (mips_ecoff_backend_data), coff-alpha.c
133 (alpha_ecoff_backend_data): Change casts of aux_in and aux_out
134 fields to match yesterday's changes.
135
136 * coffcode.h (coff_write_relocs): If SELECT_RELOC is defined, pass
137 in the internal_reloc itself, not the type.
138 * coff-apollo.c, coff-h8300.c, coff-h8500.c, coff-i386.c,
139 coff-m68k.c, coff-sh.c, coff-we32k.c, coff-z8k.c: Changed

148 accordingly.
149 * libcoff.h: Rebuilt.
150 * coffswap.h (coff_swap_aux_in, coff_swap_aux_out): Accept new
151 arguments. If RS6000COFF_C, only treat C_EXT and C_HIDEXT
152 specially if this is the last aux entry.
153 * coffgen.c (coff_write_symbol, coff_get_normalized_symtab): Pass
154 new arguments to swap_aux functions.
155

157
158 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
159 (only testing for m68k and vax at the moment); do verify that the
160 preprocessor didn't trash the arch name inside the string version.
161 Don't print out "pagesize =" line that prevents output from
162 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
163 results.

174
175 * hosts/vaxbsd.h (HOST_STACK_END_ADDR): Vax BSD doesn't define

177
178 Thu Jan 27 13:54:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

189
190 * som.c, som.h (bfd_som_set_section_attributes,
191 bfd_som_set_subsection_attributes): Change parameters from char
192 to int. Following a prototype with an old-style function definition
193 in the presence of widened parameters is a GCC-ism not supported
194 by the HP compiler in ANSI mode.
195
196 Tue Jan 25 11:46:46 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

202 are used.
203
204 * archive.c (do_slurp_bsd_armap, bfd_slurp_bsd_armap_f2): Do not
205 try to overlay the internal carsyms on the external symdefs. That
206 can not work if the size of a host pointer is larger than 4 bytes.

209 bfd_xmalloc_by_size_t.
210 * opncls.c (_bfd_new_bfd): Avoid ANSI C prototype.
211

252 .pdata section based on lnnoptr field, not section header.
253 (alpha_relocate_section): Don't bother to check if r_symndx >= 0,
254 since it is unsigned.

256 coff_object_p.
257 * ecoff.c (ecoff_new_section_hook): Set alignment_power field of
258 .pdata section to 3.
259 (ecoff_compute_section_file_positions): Save the size of the

263 calling ecoff_compute_section_file_positions.
264 (ecoff_write_object_contents): Set s_lnnoptr for the .pdata
265 section from the line_filepos field. Set vstamp for the optional
266 header from the vstamp of the symbolic header.

275
276 * elfcode.h (swap_out_syms): Use elf_section_from_bfd_section to
277 get the index of a common section, rather than always using
278 SHN_COMMON (MIPS has multiple common sections).
279

281
282 * bfd/aoutx.h (aout_link_input_section_std,

293
294 * bout.c (calljx_callback, callj_callback): Use get_value to get
295 the symbol value and check for undefined symbols.
296 (get_value): If the symbol is undefined, look it up in the linker
297 hash table.
298 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
299 use get_value to get the symbol value and check for undefined

302 undefined, look it up in the linker hash table.
303

305 special meaning for normal symbols, but not for dynamic symbols.
306
307 Sat Jan 22 12:26:01 1994 Stu Grossman (grossman at cygnus.com)
308
309 * sparclynx.c: Setup appropriate macros to enable core file

326 Fri Jan 21 14:11:16 1994 Sean Fagan (sef@cygnus.com)
327
328 * nlmcode.h, liblnm.h, nlm32-alpha.c nlm32-i386.c nlm32-sparc.c:
329 The sparc (and possibly other?) NLM format requires a different
330 way to write exports, so add a write_export field to the backend
331 data (and set it to NULL for everything but the sparc).
332
333 Fri Jan 21 14:11:16 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
334
335 * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,
336 not (struct external_nlist *) NULL. info->dynrel is a PTR, not
337 a struct external_nlist *.
338
339 Fri Jan 21 09:29:01 1994 David J. Mackenzie (djm@thepub.cygnus.com)

347 to be unused.
348 * bfd-in2.h: Regenerated.

375 return value.
376 * aoutf1.h (NAME(aout,sunos4_write_object_contents)): Don't write
377 out dynamic symbols or relocs against reloc symbols, since they
378 are already in the .text section and we wouldn't know where to
379 write them anyhow.
380 (sunos4_aout_backend): Initialize read_dynamic_symbols and
381 read_dynamic_relocs fields.
382 * aout-target.h (MY(backend_data)): Initialize
383 read_dynamic_symbols and read_dynamic_relocs fields.
384

386
387 * hosts/alphaosf.h (uint64e_type, uint64_type, int64_type): Delete

410 already defined.
411
412 Wed Jan 19 00:02:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

569 BFD64.
570 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

670 external symbols.
