Xing GUO 12224162a1 [dsymutil][doc] Improve documentation.
This change helps improve `dsymutil` documentation.

- Add missing options
- Re-arrange options in alphabetical order
- Wrap inline options in double-back-quote
- `-v` is for `--version` not `--verbose`

dsymutil - manipulate archived DWARF debug symbol files
=======================================================
.. program:: dsymutil
SYNOPSIS
--------
| :program:`dsymutil` [*options*] *executable*
DESCRIPTION
-----------
:program:`dsymutil` links the DWARF debug information found in the object files
for an executable *executable* by using debug symbols information contained in
its symbol table. By default, the linked debug information is placed in a
``.dSYM`` bundle with the same name as the executable.
OPTIONS
-------
.. option:: --accelerator=<accelerator type>
Specify the desired type of accelerator table. Valid options are 'Apple',
'Dwarf' and 'Default'.
.. option:: --arch=<arch>
Link DWARF debug information only for specified CPU architecture types.
Architectures may be specified by name. When using this option, an error will
be returned if any architectures can not be properly linked. This option can
be specified multiple times, once for each desired architecture. All CPU
architectures will be linked by default and any architectures that can't be
properly linked will cause :program:`dsymutil` to return an error.
.. option:: --dump-debug-map
Dump the *executable*'s debug-map (the list of the object files containing the
debug information) in YAML format and exit. Not DWARF link will take place.
.. option:: -f, --flat
Produce a flat dSYM file. A ``.dwarf`` extension will be appended to the
executable name unless the output file is specified using the ``-o`` option.
.. option:: -h, --help
Print this help output.
.. option:: -j <n>, --num-threads=<n>
Specifies the maximum number (``n``) of simultaneous threads to use when
linking multiple architectures.
.. option:: --no-odr
Do not use ODR (One Definition Rule) for uniquing C++ types.
.. option:: --no-output
Do the link in memory, but do not emit the result file.
.. option:: --no-swiftmodule-timestamp
Don't check the timestamp for swiftmodule files.
.. option:: --object-prefix-map=<prefix=remapped>
Remap object file paths (but no source paths) before processing. Use
this for Clang objects where the module cache location was remapped using
``-fdebug-prefix-map``; to help dsymutil find the Clang module cache.
.. option:: --oso-prepend-path=<path>
Specifies a ``path`` to prepend to all debug symbol object file paths.
.. option:: -o <filename>, --out <filename>
Specifies an alternate ``path`` to place the dSYM bundle. The default dSYM
bundle path is created by appending ``.dSYM`` to the executable name.
.. option:: --papertrail
When running dsymutil as part of your build system, it can be desirable for
warnings to be part of the end product, rather than just being emitted to the
output stream. When enabled warnings are embedded in the linked DWARF debug
information.
.. option:: --remarks-output-format <format>
Specify the format to be used when serializing the linked remarks.
.. option:: --remarks-prepend-path <path>
Specify a directory to prepend the paths of the external remark files.
.. option:: --symbol-map <bcsymbolmap>
Update the existing dSYMs inplace using symbol map specified.
.. option:: -s, --symtab
Dumps the symbol table found in *executable* or object file(s) and exits.
.. option:: -S
Output textual assembly instead of a binary dSYM companion file.
.. option:: --toolchain <toolchain>
Embed the toolchain in the dSYM bundle's property list.
.. option:: -u, --update
Update an existing dSYM file to contain the latest accelerator tables and
other DWARF optimizations. This option will rebuild the '.apple_names' and
'.apple_types' hashed accelerator tables.
.. option:: --verbose
Display verbose information when linking.
.. option:: --verify
Run the DWARF verifier on the linked DWARF debug info.
.. option:: -v, --version
Display the version of the tool.
.. option:: -y
Treat *executable* as a YAML debug-map rather than an executable.
.. option:: -z, --minimize
When used when creating a dSYM file, this option will suppress the emission of
the .debug_inlines, .debug_pubnames, and .debug_pubtypes sections since
dsymutil currently has better equivalents: .apple_names and .apple_types. When
used in conjunction with ``--update`` option, this option will cause redundant
accelerator tables to be removed.
EXIT STATUS
-----------
:program:`dsymutil` returns 0 if the DWARF debug information was linked
successfully. Otherwise, it returns 1.
