63 * elfcode.h (bfd_section_from_shdr): Get vma and alignment_power
64 of an SHT_STRTAB section from sh_addr and sh_addralign, rather

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

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

137 entry has type STY_LD change the x_scnlen into a pointer to a
138 symbol and set fix_scnlen. Also, for a C_BSTAT symbol, change the
139 value into a pointer to a symbol and set fix_value.

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

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

174 * ecofflink.c (bfd_ecoff_debug_externals): If a small undefined
175 symbol has a value in the ECOFF symbol but not in the BFD symbol,
176 keep the value in the ECOFF symbol. This helps gas.
178 * linker.c (_bfd_generic_link_output_symbols,
179 _bfd_generic_link_write_global_symbol): Don't require that all
180 references to a common symbol be themselves common symbols.

220 new arguments to swap_aux functions.

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

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

246 * linker.c (generic_link_add_symbol_list): If symbol is common,

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

325 (ecoff_compute_section_file_positions): Save the size of the

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

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

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

447 read_dynamic_relocs fields.
448 * aout-target.h (MY(backend_data)): Initialize

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