49 cruft (like the #pragma alloca for AIX).

864 bfd_coff_symname_in_debug returns true, don't put symbol name in

913 * coff-mips.c (mips_ecoff_backend_data), coff-alpha.c
914 (alpha_ecoff_backend_data): Change casts of aux_in and aux_out

939 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
940 (only testing for m68k and vax at the moment); do verify that the

972 bfd_som_set_subsection_attributes): Change parameters from char

1080 use get_value to get the symbol value and check for undefined

1083 undefined, look it up in the linker hash table.
1085 * aoutx.h (translate_symbol_table): The string index 0 has a

1110 The sparc (and possibly other?) NLM format requires a different
1111 way to write exports, so add a write_export field to the backend
1112 data (and set it to NULL for everything but the sparc).

1162 read_dynamic_relocs fields.

1220 the DYNAMIC flag for the BFD.
1221 (NAME(bfd_elf,write_object_contents)): Don't try to write out a

1273 * ecofflink.c: Extensive changes to compress and merge debugging
1274 information, and to write some of out directly rather than saving

1278 sym_filepos as well.
1279 (ecoff_get_extr): Use ifdmap instead of ifdbase.

1349 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
1351 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

1354 * configure.in (nlm32_alpha_vec): Set target64 to true.
1356 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
1357 different, so there is no point to providing a generic one.
1358 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
1359 in the backend accessor macros; that should no longer be possible.
1360 * targets.c (target_vector): Removed nlm32_big_generic_vec,
1361 nlm64_big_generic_vec, nlm64_little_generic_vec.
