19 linker stubs into a single function (so they can easily share a

114 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
115 number rather than HP9000S800_ID. Note som.c is careful

234 use for bounds checking.
236 * linker.c (default_indirect_link_order): In assertion, compare
237 link_order size field against cooked size, not raw size, of input
240 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
242 (aligncode): When shrinking, the addend should be set to the
243 current offset in the section plus the number of bytes of padding
244 that will actually be retained.
245 (b_out_relax_section): If a section contains no relocations, don't
246 bother processing them.

331 Make all callers of malloc or realloc (including via obstacks)
332 check the result for NULL. Most set bfd_error to no_memory and
333 return in that case; a few are harder to fix, and are marked

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

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

812 bfd_som_set_subsection_attributes): Change parameters from char

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

1002 read_dynamic_relocs fields.
1003 * aout-target.h (MY(backend_data)): Initialize

1113 * ecofflink.c: Extensive changes to compress and merge debugging
1114 information, and to write some of out directly rather than saving

1118 sym_filepos as well.
1119 (ecoff_get_extr): Use ifdmap instead of ifdbase.

1181 there is no output section.
1183 Thu Jan 6 14:37:42 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1185 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
1186 count it as a wrong format error, not a system call error, since

1191 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

1196 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
1197 different, so there is no point to providing a generic one.

1199 in the backend accessor macros; that should no longer be possible.

1257 against a section symbol, subtract the VMA of the input section.
1258 (aout_link_input_section_ext): Likewise.

1293 * bfd-in.h, hash.c: Change bfd_hash_allocate argument from size_t
1294 to unsigned int, because size_t may not be defined in bfd.h.
1295 * bfd-in2.h: Rebuilt.

1335 and do the swapping here rather than calling ntohl from the N_*
1336 macros. This cleans up assumptions about the size of a host long,
1337 the existence to ntohl, etc.
1339 Sat Jan 1 13:50:05 1994 Rob Savoye (rob@darkstar.cygnus.com)
