9 obsolete make_unique_section.

34 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
36 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
37 cruft (like the #pragma alloca for AIX).
38 In addition to that problem, the C alloca calls xmalloc, which

40 following changes remove all uses of alloca from BFD.

388 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
390 (aligncode): When shrinking, the addend should be set to the
391 current offset in the section plus the number of bytes of padding
392 that will actually be retained.
393 (b_out_relax_section): If a section contains no relocations, don't
394 bother processing them.
395 (b_out_get_relocated_section_contents): Set reloc_done. Assert

479 Make all callers of malloc or realloc (including via obstacks)
480 check the result for NULL. Most set bfd_error to no_memory and
481 return in that case; a few are harder to fix, and are marked
482 with "FIXME <return type>".

960 bfd_som_set_subsection_attributes): Change parameters from char

1027 .pdata section to 3.

1045 * elfcode.h (swap_out_syms): Use elf_section_from_bfd_section to
1046 get the index of a common section, rather than always using

1068 use get_value to get the symbol value and check for undefined
1070 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1071 undefined, look it up in the linker hash table.
1073 * aoutx.h (translate_symbol_table): The string index 0 has a
1074 special meaning for normal symbols, but not for dynamic symbols.

1098 The sparc (and possibly other?) NLM format requires a different
1099 way to write exports, so add a write_export field to the backend
1100 data (and set it to NULL for everything but the sparc).

1208 the DYNAMIC flag for the BFD.

1261 * ecofflink.c: Extensive changes to compress and merge debugging

1266 sym_filepos as well.
1267 (ecoff_get_extr): Use ifdmap instead of ifdbase.

1339 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

1344 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
1345 different, so there is no point to providing a generic one.
1346 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
1347 in the backend accessor macros; that should no longer be possible.
