113 * srec.c (srec_write_record): Put CONST keyword for "src" before
114 "unsigned", some compilers don't like it after "unsigned".
115 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to
116 "val" in prototype declaration because some compilers don't like
117 arguments whose names are the same as types.

121 * aoutx.h (aout_link_check_ar_symbols): Correct test for whether

145 entry has type STY_LD change the x_scnlen into a pointer to a
146 symbol and set fix_scnlen. Also, for a C_BSTAT symbol, change the
147 value into a pointer to a symbol and set fix_value.

156 (coff_write_symbols): Initialize debug_string_size to 0. If
157 bfd_coff_symname_in_debug returns true, don't put symbol name in

159 debug_string_size is not 0, check that it matches the size of the

182 * ecofflink.c (bfd_ecoff_debug_externals): If a small undefined
183 symbol has a value in the ECOFF symbol but not in the BFD symbol,
184 keep the value in the ECOFF symbol. This helps gas.
186 * linker.c (_bfd_generic_link_output_symbols,
187 _bfd_generic_link_write_global_symbol): Don't require that all
188 references to a common symbol be themselves common symbols.

223 * libcoff.h: Rebuilt.
224 * coffswap.h (coff_swap_aux_in, coff_swap_aux_out): Accept new

228 new arguments to swap_aux functions.

232 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
233 (only testing for m68k and vax at the moment); do verify that the
234 preprocessor didn't trash the arch name inside the string version.

236 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
238 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.

265 bfd_som_set_subsection_attributes): Change parameters from char
266 to int. Following a prototype with an old-style function definition
267 in the presence of widened parameters is a GCC-ism not supported
268 by the HP compiler in ANSI mode.

333 (ecoff_compute_section_file_positions): Save the size of the

350 * elfcode.h (swap_out_syms): Use elf_section_from_bfd_section to
351 get the index of a common section, rather than always using
352 SHN_COMMON (MIPS has multiple common sections).
354 * elf32-hppa.c (hppa_elf_gen_reloc_type): Typo (== for =).
356 * bfd/aoutx.h (aout_link_input_section_std,

376 undefined, look it up in the linker hash table.
378 * aoutx.h (translate_symbol_table): The string index 0 has a
379 special meaning for normal symbols, but not for dynamic symbols.

403 The sparc (and possibly other?) NLM format requires a different
404 way to write exports, so add a write_export field to the backend
405 data (and set it to NULL for everything but the sparc).
407 Fri Jan 21 14:11:16 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
409 * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,

455 read_dynamic_relocs fields.
456 * aout-target.h (MY(backend_data)): Initialize

461 * hosts/alphaosf.h (uint64e_type, uint64_type, int64_type): Delete
462 typedefs, since HOST_64_BIT will take care of defining them in
465 Wed Jan 19 17:28:59 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
467 * config/alphaosf.mh (HDEFINES): Don't define HOST_64_BIT here;
