2002-11-07 Michal Ludvig <mludvig@suse.cz>
* dwarf2.c (read_indirect_string, read_abbrevs, decode_line_info,
_bfd_dwarf2_find_nearest_line): Use
bfd_simple_get_relocated_section_contents() instead of
bfd_get_section_contents().
* reloc.c (bfd_perform_relocation): Add sanity check.
* simple.c (simple_get_relocated_section_contents): If the section
does not have any relocs associated with it, just return the
unadjusted contents.
