       GNU strip discards all symbols from object files objfile.  The list of object files may
       include archives.  At least one object file must be given.

       strip modifies the files named in its argument, rather than writing modified copies under
       different names.


       -F bfdname
           Treat the original objfile as a file with the object code format bfdname, and rewrite
           it in the same format.

           Show a summary of the options to strip and exit.

           Display a list showing all architectures and object formats available.

       -I bfdname
           Treat the original objfile as a file with the object code format bfdname.

       -O bfdname
           Replace objfile with a file in the output format bfdname.

       -R sectionname
           Remove any section named sectionname from the output file.  This option may be given
           more than once.  Note that using this option inappropriately may make the output file
           unusable.  The wildcard character * may be given at the end of sectionname.  If so,
           then any section starting with sectionname will be removed.

           Remove all symbols.

           Remove debugging symbols only.

           Remove the contents of all DWARF .dwo sections, leaving the remaining debugging
           sections and all symbols intact.  See the description of this option in the objcopy
           section for more information.

           Remove all symbols that are not needed for relocation processing.

       -K symbolname
           When stripping symbols, keep symbol symbolname even if it would normally be stripped.
           This option may be given more than once.

       -N symbolname
           Remove symbol symbolname from the source file. This option may be given more than
           once, and may be combined with strip options other than -K.

       -o file
           Put the stripped output in file, rather than replacing the existing file.  When this
           argument is used, only one objfile argument may be specified.

           Preserve the access and modification dates of the file.

           Operate in deterministic mode.  When copying archive members and writing the archive
           index, use zero for UIDs, GIDs, timestamps, and use consistent file modes for all

           If binutils was configured with --enable-deterministic-archives, then this mode is on
           by default.  It can be disabled with the -U option, below.

           Do not operate in deterministic mode.  This is the inverse of the -D option, above:
           when copying archive members and writing the archive index, use their actual UID, GID,
           timestamp, and file mode values.

           This is the default unless binutils was configured with

           Permit regular expressions in symbolnames used in other command line options.  The
           question mark (?), asterisk (*), backslash (\) and square brackets ([]) operators can
           be used anywhere in the symbol name.  If the first character of the symbol name is the
           exclamation point (!) then the sense of the switch is reversed for that symbol.  For

                     -w -K !foo -K fo*

           would cause strip to only keep symbols that start with the letters "fo", but to
           discard the symbol "foo".

           Remove non-global symbols.

           Remove compiler-generated local symbols.  (These usually start with L or ..)

           When stripping a file, perhaps with --strip-debug or --strip-unneeded, retain any
           symbols specifying source file names, which would otherwise get stripped.

           Strip a file, removing contents of any sections that would not be stripped by
           --strip-debug and leaving the debugging sections intact.  In ELF files, this preserves
           all note sections in the output.

           The intention is that this option will be used in conjunction with --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:

           1.<Link the executable as normal.  Assuming that is is called>
               "foo" then...

           1.<Run "objcopy --only-keep-debug foo foo.dbg" to>
               create a file containing the debugging info.

           1.<Run "objcopy --strip-debug foo" to create a>
               stripped executable.

           1.<Run "objcopy --add-gnu-debuglink=foo.dbg foo">
               to add a link to the debugging info into the stripped executable.

           Note---the choice of ".dbg" as an extension for the debug info file is arbitrary.
           Also the "--only-keep-debug" step is optional.  You could instead do this:

           1.<Link the executable as normal.>
           1.<Copy "foo" to "foo.full">
           1.<Run "strip --strip-debug foo">
           1.<Run "objcopy --add-gnu-debuglink=foo.full foo">

           i.e., the file pointed to by the --add-gnu-debuglink can be the full executable.  It
           does not have to be a file created by the --only-keep-debug switch.

           Note---this switch is only intended for use on fully linked files.  It does not make
           sense to use it on object files where the debugging information may be incomplete.
           Besides the gnu_debuglink feature currently only supports the presence of one filename
           containing debugging information, not multiple filenames on a one-per-object-file

           Show the version number for strip.

           Verbose output: list all object files modified.  In the case of archives, strip -v
           lists all members of the archive.

           Read command-line options from file.  The options read are inserted in place of the
           original @file option.  If file does not exist, or cannot be read, then the option
           will be treated literally, and not removed.

           Options in file are separated by whitespace.  A whitespace character may be included
           in an option by surrounding the entire option in either single or double quotes.  Any
           character (including a backslash) may be included by prefixing the character to be
           included with a backslash.  The file may itself contain additional @file options; any
           such options will be processed recursively.
