127
128 * section.c (bfd_get_section_contents): Since this function reads
129 unrelocated contents, the section's raw size is always the one to
130 use for bounds checking.
131

142 bother processing them.

147 that reloc->addend falls between the current source offset and the
148 raw size of the input section.
149
150 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
151 bout. Default with no version number is still bout. Support

155 fixed some comments, removed some "#if 1" lines.

563
564 * aoutx.h (aout_link_check_ar_symbols): Correct test for whether

845 * nlmcode.h, liblnm.h, nlm32-alpha.c nlm32-i386.c nlm32-sparc.c:
846 The sparc (and possibly other?) NLM format requires a different
847 way to write exports, so add a write_export field to the backend
848 data (and set it to NULL for everything but the sparc).
849
850 Fri Jan 21 14:11:16 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
851
852 * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,
853 not (struct external_nlist *) NULL. info->dynrel is a PTR, not

864 to be unused.
865 * bfd-in2.h: Regenerated.
866

895 are already in the .text section and we wouldn't know where to
896 write them anyhow.

898 read_dynamic_relocs fields.
899 * aout-target.h (MY(backend_data)): Initialize

903
904 * hosts/alphaosf.h (uint64e_type, uint64_type, int64_type): Delete

940 output the calculated value and don't output the target symbol.
941
942 Tue Jan 18 03:54:59 1994 David J. Mackenzie (djm@thepub.cygnus.com)
943
944 * aoutx.h (translate_from_native_sym_flags): Give warning symbols
945 an (unused) nonzero section value, needed for check below.
946

954
955 * elfcode.h (elf_object_p): If there is a SHT_DYNAMIC section, set
956 the DYNAMIC flag for the BFD.
957 (NAME(bfd_elf,write_object_contents)): Don't try to write out a
958 BFD with the DYNAMIC flag set, since we don't generate the program
959 header table correctly.

1008
1009 * ecofflink.c: Extensive changes to compress and merge debugging

1080
1081 * nlmcode.h (nlm_object_p): If we can't read the fixed header,

1086 BFD64.
1087 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.
1088 (BFD64_BACKENDS): Add nlm32-alpha.o. It depends on 64 bit

1090 * configure.in (nlm32_alpha_vec): Set target64 to true.
1091
1092 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
1093 different, so there is no point to providing a generic one.
1094 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
1095 in the backend accessor macros; that should no longer be possible.
1096 * targets.c (target_vector): Removed nlm32_big_generic_vec,

1187 external symbols.
1188

1230 * aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
1231 and do the swapping here rather than calling ntohl from the N_*
1232 macros. This cleans up assumptions about the size of a host long,
