-----------
:program:`llvm-symbolizer` reads object file names and addresses from standard
-input and prints corresponding source code locations to standard output. This
+input and prints corresponding source code locations to standard output.
+If object file is specified in command line, :program:`llvm-symbolizer` reads
+only addresses from standard input. This
program uses debug info sections and symbol table in the object files.

OPTIONS
-------
-.. option:: -functions
+.. option:: -obj
- Print function names as well as source file/line locations. Defaults to true.
+ Path to object file to be symbolized.
+
+.. option:: -functions=[none|short|linkage]
+
+ Specify the way function names are printed (omit function name,
+ print short function name, or print full linkage name, respectively).
+ Defaults to ``linkage``.
.. option:: -use-symbol-table
If a source code location is in an inlined function, prints all the
inlnied frames. Defaults to true.
+.. option:: -default-arch
+
+ If a binary contains object files for multiple architectures (e.g. it is a
+ Mach-O universal binary), symbolize the object file for a given architecture.
+ You can also specify architecture by writing ``binary_name:arch_name`` in the
+ input (see example above). If architecture is not specified in either way,
+ address will not be symbolized. Defaults to empty string.
