+Do not copy debugging symbols or sections from the source file.
@item --strip-unneeded
Strip all symbols that are not needed for relocation processing.
@itemx --weaken-symbol=@var{symbolname}
Make symbol @var{symbolname} weak. This option may be given more than once.
+@item -w
+@itemx --wildcard
+Permit regular expressions in @var{symbolname}s used in other command

+point (!) then the sense of the switch is reversed for that symbol.
+For example:
+
+@smallexample
+ -w -W !foo -W fo*
+@end smallexample
+
+would cause objcopy to weaken all symbols that start with ``fo''
+except for the symbol ``foo''.

+@item --redefine-syms=@var{filename}
+Apply @option{--redefine-sym} to each symbol pair "@var{old} @var{new}"
+listed in the file @var{filename}. @var{filename} is simply a flat file,
+with one symbol pair per line. Line comments may be introduced by the hash
+character. This option may be given more than once.
+
@item --weaken
Change all global symbols in the file to be weak. This can be useful
when building an object which will be linked against other objects using
new code, but other applications still depend on the original code
being used.
+@item --writable-text
+Mark the output text as writable. This option isn't meaningful for all
+object file formats.
+
+@item --readonly-text
+Make the output text write protected. This option isn't meaningful for all

@var{string}.
+@item --add-gnu-debuglink=@var{path-to-file}
+Creates a .gnu_debuglink section which contains a reference to @var{path-to-file}
+and adds it to the output file.
+
+@item --only-keep-debug
+Strip a file, removing any sections that would be stripped by
+@option{--strip-debug} and leaving the debugging sections.
+
+The intention is that this option will be used in conjunction with
+@option{--add-gnu-debuglink} to create a two part executable. One a
+stripped binary which will occupy less space in RAM and in a
+distribution and the second a debugging information file which is only
+needed if debugging abilities are required. The suggested procedure
+to create these files is as follows:
+
+@enumerate
+@item Link the executable as normal. Assuming that is is called
+@code{foo} then...
+@item Run @code{objcopy --only-keep-debug foo foo.dbg} to
+create a file containing the debugging info.
+@item Run @code{objcopy --strip-debug foo} to create a
+stripped executable.
+@item Run @code{objcopy --add-gnu-debuglink=foo.dbg foo}
+to add a link to the debugging info into the stripped executable.
+@end enumerate
+
+Note - the choice of @code{.dbg} as an extension for the debug info
+file is arbitrary. Also the @code{--only-keep-debug} step is
+optional. You could instead do this:
+
+@enumerate
+@item Link the executable as normal.
+@item Copy @code{foo} to @code{foo.full}
+@item Run @code{objcopy --strip-debug foo}
+@item Run @code{objcopy --add-gnu-debuglink=foo.full foo}
