+==============================================
+
+.. program:: llvm-objcopy
+
+SYNOPSIS
+--------
+
+:program:`llvm-objcopy` *input* [*output*] [*options*]
+
+DESCRIPTION
+-----------
+
+:program:`llvm-objcopy` is a tool to copy and manipulate objects. In basic
+usage, it makes a semantic copy of the input to the output. If any options are
+specified, the output may be modified along the way, e.g. by removing sections.
+
+If no output file is specified, the input file is modified in-place. If "-" is
+specified for the input file, the input is read from the program's standard
+input stream. If "-" is specified for the output file, the output is written to
+the standard output stream of the program.
+
+If the input is an archive, any requested operations will be applied to each
+archive member individually.
+
+The tool is still in active development, but in most scenarios it works as a
+drop-in replacement for GNU's :program:`objcopy`.
+
+GENERIC AND CROSS-PLATFORM OPTIONS
+----------------------------------
+
+The following options are either agnostic of the file format, or apply to
+multiple file formats.
+
+.. option:: --add-gnu-debuglink <debug-file>
+
+ Add a .gnu_debuglink section for ``<debug-file>`` to the output.
+
+.. option:: --disable-deterministic-archives, -U
+
+ Use real values for UIDs, GIDs and timestamps when updating archive member
+ headers.
+
+.. option:: --discard-all, -x
+
+ Remove most local symbols from the output. Different file formats may limit
+ this to a subset of the local symbols. For example, file and section symbols in
+ ELF objects will not be discarded.
+
+.. option:: --enable-deterministic-archives, -D
+
+ Enable deterministic mode when copying archives, i.e. use 0 for archive member
+ header UIDs, GIDs and timestamp fields. On by default.
+
+.. option:: --help, -h
+
+ Print a summary of command line options.
+
+.. option:: --only-section <section>, -j
+
+ Remove all sections from the output, except for sections named ``<section>``.
+ Can be specified multiple times to keep multiple sections.
+
+.. option:: --regex
+
+ If specified, symbol and section names specified by other switches are treated
+ as extended POSIX regular expression patterns.
+
+.. option:: --remove-section <section>, -R
+
+ Remove the specified section from the output. Can be specified multiple times
+ to remove multiple sections simultaneously.
+
+.. option:: --strip-all-gnu
+
+ Remove all symbols, debug sections and relocations from the output. This option
+ is equivalent to GNU :program:`objcopy`'s ``--strip-all`` switch.
+
+.. option:: --strip-all, -S
+
+ For ELF objects, remove all symbols and non-alloc sections not within segments
+ from the output.
+
+ For COFF objects, remove all symbols, debug sections, and relocations from the
+ output.
+
+.. option:: --strip-debug, -g
+
+ Remove all debug sections from the output.
+
+.. option:: --strip-symbol <symbol>, -N
+
+ Remove all symbols named ``<symbol>`` from the output. Can be specified
+ multiple times to remove multiple symbols.
+
+.. option:: --strip-symbols <filename>
+
+ Remove all symbols whose names appear in the file ``<filename>``, from the
+ output. In the file, each line represents a single symbol name, with leading
+ and trailing whitespace ignored, as is anything following a '#'. Can be
+ specified multiple times to read names from multiple files.
+
+.. option:: --strip-unneeded-symbol <symbol>
+
+ Remove from the output all symbols named ``<symbol>`` that are local or
+ undefined and are not required by any relocation.
+
+.. option:: --strip-unneeded-symbols <filename>
+
+ Remove all symbols whose names appear in the file ``<filename>``, from the
+ output, if they are local or undefined and are not required by any relocation.
+ In the file, each line represents a single symbol name, with leading and
+ trailing whitespace ignored, as is anything following a '#'. Can be specified
+ multiple times to read names from multiple files.
+
+.. option:: --strip-unneeded
+
+ Remove from the output all local or undefined symbols that are not required by
+ relocations.
+
+.. option:: --version, -V
+
+  Display the version of this program.
+
+COFF-SPECIFIC OPTIONS
+---------------------
+
+The following options are implemented only for COFF objects.
+
+.. option:: --only-keep-debug
+
+ Remove the contents of non-debug sections from the output, but keep the section
+ headers.
+
+ELF-SPECIFIC OPTIONS
+--------------------
+
+The following options are implemented only for ELF objects.
+
+.. option:: --add-section <section=file>
+
+ Add a section named ``<section>`` with the contents of ``<file>`` to the
+ output. The section will be of type `SHT_NOTE`, if the name starts with
+ ".note". Otherwise, it will have type `SHT_PROGBITS`. Can be specified multiple
+ times to add multiple sections.
+
+.. option:: --add-symbol <name>=[<section>:]<value>[,<flags>]
+
+ Add to the output a new symbol called ``<name>`` to the symbol table, in the
+ section named ``<section>``, with value ``<value>``. If ``<section>`` is not
+ specified, the symbol is added as an absolute symbol. The ``<flags>`` affect
+ the symbol properties. Accepted values are:
+
+ - `global` = the symbol will have global binding.
+ - `local` = the symbol will have local binding.
+ - `weak` = the symbol will have weak binding.
+ - `default` = the symbol will have default visibility.
+ - `hidden` = the symbol will have hidden visibility.
+ - `file` = the symbol will be an `STT_FILE` symbol.
+ - `section` = the symbol will be an `STT_SECTION` symbol.
+ - `object` = the symbol will be an `STT_OBJECT` symbol.
+ - `function` = the symbol will be an `STT_FUNC` symbol.
+ - `indirect-function` = the symbol will be an `STT_GNU_IFUNC` symbol.
+
+ Additionally, the following flags are accepted but ignored: `debug`,
+ `constructor`, `warning`, `indirect`, `synthetic`, `unique-object`, `before`.
+
+ Can be specified multiple times to add multiple symbols.

+EXIT STATUS
+-----------
+
+:program:`llvm-objcopy` exits with a non-zero exit code if there is an error.
+Otherwise, it exits with code 0.
+
+BUGS
+----
+
+To report bugs, please visit <http://llvm.org/bugs/>.
+
+There is a known issue with :option:`--input-target` and :option:`--target`
+causing only ``binary`` and ``ihex`` formats to have any effect. Other values
+will be ignored and :program:`llvm-objcopy` will attempt to guess the input
+format.
