This patch adds a number of new test cases that cover various llvm-objcopy and llvm-strip features that had missing test coverage of various descriptions: * --add-section - checked the shdr properties, not just the content. * Dedicated test case for --add-symbol when there are many sections. * Show that --change-start accepts negative values without overflow. This was previously present but got lost between review versions. * --dump-section - show that multiple sections can be dumped simultaneously to different files, and that an error is reported when a section cannot be found. * --globalize-symbol(s) - show that symbols that are not mentioned are not globalized, if they would otherwise be, and that missing symbols from the list do not cause problems. * --keep-global-symbol - show that the --regex option can be used in conjunction with this option. * --keep-symbol - show that the --regex option can be used in conjunction with this option. * --localize-symbol(s) - show that symbols that are not mentioned are not localized, if they would otherwise be, and that missing symbols from the list do not cause problems. * --prefix-alloc-sections - show the behaviour of an empty string argument and multiple arguments. * --prefix-symbols - show the behaviour of an empty string argument and multiple arguments. Also show the option applies to undefined symbols. * --redefine-symbol - show that symbols with no name can be renamed, that it is not an error if a symbol is not specified, and that the option doesn't chain (i.e. --redefine-sym a=b --redefine-sym b=c does not redefine a as c). * --rename-section - show that all section flags are preserved if none are specified. Also show that the option does not chain. * --set-section-alignment - show that only specified sections have their alignments changed. * --set-section-flags - show which section flags are preserved when this option is used. Also show that unspecified sections are not affected. * --preserve-dates - show that -p is an alias of --preserve-dates. * --strip-symbol - show that --regex works with this option for llvm-objcopy as well as llvm-strip. * --strip-unneeded-symbol(s) - show more clearly that needed symbols are not stripped even if requested by this option. * --allow-broken-links - show the sh_link of a symbol table is set to 0 when its string table has been removed when this option is specified. * --weaken-symbol(s) - show that symbols that are not mentioned are not weakened, if they would otherwise be, and that missing symbols from the list do not cause problems. * --wildcard - show the wildcard behaviour for several options that were previously unchecked.
