DESCRIPTION
Returns the relocated contents of section @var{sec}. The symbols in
@var{symbol_table} will be used, or the symbols from @var{abfd} if
- @var{symbol_table} is NULL. The output offsets for all sections will
+ @var{symbol_table} is NULL. The output offsets for debug sections will
be temporarily reset to 0. The result will be stored at @var{outbuf}
or allocated with @code{bfd_malloc} if @var{outbuf} is @code{NULL}.
- Generally all sections in @var{abfd} should have their
- @code{output_section} pointing back to the original section.
-
Returns @code{NULL} on a fatal error; ignores errors applying
particular relocations.
