2004-12-15 Jan Beulich <jbeulich@novell.com> * doc/binutils.texi: Document --strip-unneeded-symbol and --strip-unneeded-symbols. * objcopy.c (strip_unneeded_list): New. (enum command_line_switch): Add OPTION_STRIP_UNNEEDED_SYMBOL and OPTION_STRIP_UNNEEDED_SYMBOLS. (copy_options): Add --strip-unneeded-symbol and --strip-unneeded-symbols. (copy_usage): Likewise. (filter_symbols): Suppress copying of symbol if in strip_unneeded_list and the symbol is not needed. (copy_main): Handle OPTION_STRIP_UNNEEDED_SYMBOL and OPTION_STRIP_UNNEEDED_SYMBOLS.
